    The objective of this study is to provide accurate, georeferenced maps of benthic habitats to assist in the siting of a new wastewater treatment plant outfall and the assessment of habitats of endangered, threatened, and economically important species. The mapping was conducted in the fall of 1999 using two complementary techniques: side-scan sonar and underwater videography. Products derived from these techniques include geographic information system (GIS) compatible polygon data of substrate type and vegetation cover, including eelgrass and kelp. Additional GIS overlays include underwater video track line data of total macroalgae, selected macroalgal species, fish, and macroinvertebrates. The combined tools of geo-referenced side-scan sonar and underwater video is a powerful technique for assessing and mapping of nearshore habitat in Puget Sound. Side-scan sonar offers the ability to map eelgrass with high spatial accuracy and resolution, and provides information on patch size, shape, and coverage. It also provides information on substrate change and location of specific targets (e.g., piers, docks, pilings, large boulders, debris piles). The addition of underwater video is a complementary tool providing both groundtruthing for the sonar and additional information on macro fauna and flora. As a groundtruthing technique, the video was able to confirm differences between substrate types, as well as detect subtle spatial changes in substrate. It also verified information related to eelgrass, including the density classification categories and the type of substrate associated with eelgrass, which could not be determined easily with side- scan sonar. Video is also a powerful tool for mapping the location of macroalgae, (including kelp and Ulva), fish and macroinvertebrates. The ability to geo-locate these resources in their functional habitat provides an added layer of information and analytical potential.

  3. King County Earthworks: Land Reclamation as Sculpture

    NSDL National Science Digital Library

    2013-11-04

    Can land reclamation be public art? It most certainly can and large scale installations can be found in abundance from California to Maine. This rather wonderful project appeared in Washington's King County in the summer of 1979. The King County Archives brought together original interviews, photos, and other documents for this marvelous exploration of a unique and trend-setting endeavor. The intent of the project was to have artists create various earthworks on land that had been environmentally damaged. The first phase was a demonstration project, then other artists moved on to create six different sites. The first demonstration project was crafted by well-known artist Robert Morris and there are a number of videos, explanatory essays, and diagrams documenting this crafty and fascinating experiment in public art.

  4. History and hydrologic effects of ground water use in Kings, Queens, and western Nassau counties, Long Island, New York

    Ground-water withdrawals from the aquifers underlying Kings and Queens Counties varied temporally and spatially during the 20th century and caused extreme changes in water levels. The resultant lowering of water levels during periods of heavy pumping caused saltwater intrusion in nearshore areas and the migration of contaminants from land surface into deep aquifers. The recovery of water levels in response to countywide curtailment of pumping has resulted in the flooding of underground structures. Combined withdrawals for public and industrial supply in Kings and Queens Counties were greatest during the 1930's--about 130 million gallons per day. During this period, a large cone of depression developed in the water table in Kings County; within this depression, water levels were about 45 feet lower than in 1903. All pumping for public supply was halted in Kings County in 1947, and in Jamaica (in Queens County) in 1974. Water levels in Kings County had recovered by 1974 and have remained similar to those of 1903 since then, except for minor localized drawdowns due to industrial-supply or dewatering withdrawals. A large cone of depression that had formed in southeastern Queens County before 1974 has now (1997) disappeared. The estimated combined withdrawal for public supply and industrial supply in Kings and Queens Counties in 1996 was only about 50 million gallons per day. The water-level recoveries in the water-table and confined aquifers generally have resulted in the dilution and dispersion of residual salty and nitrate-contaminated ground water. The majority of recently sampled wells indicate stable or decreasing chloride and nitrate concentrations in all aquifers since 1983. Organic contaminants remain in ground water in Kings, Queens, and Nassau Counties, however; the most commonly detected compounds in 1992-96 were tetrachloroethene, trichloroethene, chloroform, and total trihalomethanes. Water samples from monitoring wells in Kings County indicate a greater number of occurrences of these compounds in the upper glacial aquifer than in the Jameco-Magothy aquifer, whereas samples from public-supply wells in Queens County indicated a greater number of occurrences in the Jameco- Magothy aquifer than in the upper glacial aquifer. This distribution suggests that organic contaminants were not drawn into the deeper aquifers in Kings County before 1947, when their use was limited and deep withdrawals were greatest, and (or) that the longer period of waterlevel recovery in Kings County than in Queens has allowed greater degradation, dilution, and dispersion of any organic contaminants that might have entered the deep aquifers before the cessation of pumping in 1947.

    We studied productivity of great blue herons (Ardea herodias) at their nesting colonies in King County, western Washington in the 2000 breeding season. Rapid urbanization has been hypothesized to have limited heron population growth in recent years. Of the 354 active nests in 2000, 260 (74%) nests produced fledglings. Mean productivity for all active nests was 1.77 (SD = 1.37).

  11. Radiological Risk Assessment for King County Wastewater Treatment Division

    SciTech Connect

    Strom, Daniel J.

    2005-08-05

    Staff of the King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into the combined sanitary and storm sewer system in King County, Washington. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include "dirty bombs" that are not nuclear detonations but are explosives designed to spread radioactive material (National Council on Radiation Protection and Measurements (NCRP) 2001). Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. This document develops plausible and/or likely scenarios, including the identification of likely radioactive materials and quantities of those radioactive materials to be involved. These include 60Co, 90Sr, 137Cs, 192Ir, 226Ra, plutonium, and 241Am. Two broad categories of scenarios are considered. The first category includes events that may be suspected from the outset, such as an explosion of a "dirty bomb" in downtown Seattle. The explosion would most likely be heard, but the type of explosion (e.g., sewer methane gas or RDD) may not be immediately known. Emergency first responders must be able to quickly detect the radioisotopes previously listed, assess the situation, and deploy a response to contain and mitigate (if possible) detrimental effects resulting from the incident. In such scenarios, advance notice of about an hour or two might be available before any contaminated wastewater reaches a treatment plant. The second category includes events that could go initially undetected by emergency personnel. Examples of such a scenario would be the inadvertent or surreptitious introduction of radioactive material into the sewer system. Intact rogue radioactive sources from industrial radiography devices, well-logging apparatus, or moisture density gages may get into wastewater and be carried to a treatment plant. Other scenarios might include a terrorist deliberately putting a dispersible radioactive material into wastewater. Alternatively, a botched terrorism preparation of an RDD may result in radioactive material entering wastewater without anyone's knowledge. Drinking water supplies may also be contaminated, with the result that some or most of the radioactivity ends up in wastewater.

    This is the fifth and final report in a series documenting progress of the pre-construction eelgrass restoration and mitigation activities for the proposed King County Brightwater marine outfall, discharging to Puget Sound near Point Wells, Washington. King County began implementing a multiyear eelgrass monitoring and restoration program in 2004, with the primary goal of returning intertidal and shallow subtidal habitat and eelgrass to pre-construction conditions, after construction of the outfall. Major eelgrass mitigation program elements include: a) pre-construction monitoring, i.e., documenting initial eelgrass conditions and degree of fluctuation over a 5 year period prior to construction, b) eelgrass transplanting, including harvesting, offsite propagation and stockpiling of local plants for post-construction planting, and c) post-construction planting and subsequent monitoring, occurring in 2009 and beyond. The overall program is detailed in the Eelgrass Restoration and Biological Resources Implementation Workplan (King County 2008).

  13. Radiological Instrumentation Assessment for King County Wastewater Treatment Division

    2005-05-19

    The King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into its combined sanitary and storm sewer system. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include "dirty bombs" that are not nuclear detonations but are explosives designed to spread radioactive material. Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. Volume 2 of PNNL-15163 assesses the radiological instrumentation needs for detection of radiological or nuclear terrorism, in support of decisions to treat contaminated wastewater or to bypass the West Point Treatment Plant (WPTP), and in support of radiation protection of the workforce, the public, and the infrastructure of the WPTP. Fixed radiation detection instrumentation should be deployed in a defense-in-depth system that provides 1) early warning of significant radioactive material on the way to the WPTP, including identification of the radionuclide(s) and estimates of the soluble concentrations, with a floating detector located in the wet well at the Interbay Pump Station and telemetered via the internet to all authorized locations; 2) monitoring at strategic locations within the plant, including 2a) the pipe beyond the hydraulic ram in the bar screen room; 2b) above the collection funnels in the fine grit facility; 2c) in the sampling tank in the raw sewage pump room; and 2d) downstream of the concentration facilities that produce 6% blended and concentrated biosolids. Engineering challenges exist for these applications. It is necessary to deploy both ultra-sensitive detectors to provide early warning and identification and detectors capable of functioning in high-dose rate environments that are likely under some scenarios, capable of functioning from 10 microrems per hour (background) up to 1000 rems per hour. Software supporting fixed spectroscopic detectors is needed to provide prompt, reliable, and simple interpretations of spectroscopic outputs that are of use to operators and decision-makers. Software to provide scientists and homeland security personnel with sufficient technical detail for identification, quantification, waste management decisions, and for the inevitable forensic and attribution needs must be developed. Computational modeling using MCNP software has demonstrated that useful detection capabilities can be deployed. In particular, any of the isotopes examined can be detected at levels between 0.01 and 0.1 ?Ci per gallon. General purpose instruments that can be used to determine the nature and extent of radioactive contamination and measure radiation levels for purposes of protecting personnel and members of the public should be available. One or more portable radioisotope identifiers (RIIDs) should be available to WTD personnel. Small, portable battery-powered personal radiation monitors should be widely available WTD personnel. The personal monitors can be used for personal and group radiation protection decisions, and to alert management to the need to get expert backup. All considerations of radiological instrumentation require considerations of training and periodic retraining of personnel, as well as periodic calibration and maintenance of instruments. Routine “innocent” alarms will occur due to medical radionuclides that are legally discharged into sanitary sewers on a daily basis.

  16. Geology of the Copper King Mine area, Prairie Divide, Larimer County, Colorado (Part 1)

    1952-01-01

    The Copper King mine, in Larimer County, Colo., in the northern part of the Front Range of Colorado, was operated for a short time prior to World War II for copper and zino, but since 1949, when pitchblende was discovered on the mine dump, it has been worked for uranium. The bedrock in the mine area consists predominantly of pre-Cambrian (Silver Plums) granite with minor migmatite and metasediments--biotite-quartz-plagioclase gneiss, biotite schist, quartzite, amphibolite, amphibole skarn, and biotite skols. The metasediments occur as inclusions that trend northeast in the granite. This trend is essentially parallel to the prevailing foliation in the granite. At places the metasediments are crosscut sharply by the granite to form angular, partly discordant, steep-walled bodies in the granite. Faults, confined to a narrow zone that extends through the mine, cut both the pre-Cambrian rocks and the contained sulfide deposits. The Copper King fault, a breccia zone, contains a deposit of pitchblende; the other faults are believed to be later than the ore. The two types of mineral deposits--massive sulfide and pitchblende deposits--in the mine area, are of widely different mineralogy, age, and origin. The massive sulfide deposits are small and consist of pyrite, sphalerite, chalcopyrite, pyrrhotite, and in places magnetite in amphibole skarn, mice skols, and quartzite. The deposit at the Copper King mine has yielded small quantities of high-grade sphalerite ore. The massive sulfides are pyrometasomatic deposits of pre-Cambrian age. The pitchblende at the Copper King mine is principally in the Copper King vein, a tight, hard breccia zone that cuts through both granite and the massive sulfide deposit. A small part of the pitchblende is in small fractures near the vein and in boxwork pyrite adjacent to the vein; the post-ore faults, close to their intersection with the Copper King vein, contain some radioactive material, but elsewhere, so far as is known, they are barren. The pitchblende in the deposit forms a steeply plunging ore shoot that has a horizontal length of more than 50 feet and a vertical height of about 85 feet. The thickness of the ore shoot averages about 2 feet, but it ranges from a feather edge to about 4 feet. The hard pitch-blende is intimately intergrown with siderite; other gangue minerals include pyrite, quartz, and finely comminuted fragments of the wall rocks. The vein was repeatedly reopened during mineral deposition as shown by several stages of brecciation and recommended by the vein matter. The pitchblende deposit probably formed at intermediate temperatures and depths and, according to the Pb/U ratio, is about 60 million years old--an early Tertiary age.

    Pedestrian fatalities caused by motor vehicles in King County, WA, over a 12-month period were reviewed to examine the potential for prevention by various strategies. Cases were identified through the King County Medical Examiner's Office. Between April 1, 1985, and March 31, 1986, a total of 38 pedestrians died of motor vehicle injuries. The victims were generally children (N = 11), the elderly (N = 13), or intoxicated adults (N = 9). Supervision of the child was inadequate in 64 percent of the children's deaths. The driver was at fault in deaths of seven children, five adults, and three elderly persons. None of the children and only one of the elderly victims was injured at night. The majority of injuries occurred on major thorough-fares; only 16 percent occurred on residential streets. Possible strategies for prevention appear to include improved enforcement of pedestrian right-of-way laws, changes in vehicle design, modification of the environment (particularly in urban areas), and improved training programs for children.

    Objectives. We explored new ways to identify food deserts. Methods. We estimated physical and economic access to supermarkets for 5 low-income groups in Seattle–King County, Washington. We used geographic information system data to measure physical access: service areas around each supermarket were delineated by ability to walk, bicycle, ride transit, or drive within 10 minutes. We assessed economic access by stratifying supermarkets into low, medium, and high cost. Combining income and access criteria generated multiple ways to estimate food deserts. Results. The 5 low-income group definitions yielded total vulnerable populations ranging from 4% to 33% of the county’s population. Almost all of the vulnerable populations lived within a 10-minute drive or bus ride of a low- or medium-cost supermarket. Yet at most 34% of the vulnerable populations could walk to any supermarket, and as few as 3% could walk to a low-cost supermarket. Conclusions. The criteria used to define low-income status and access to supermarkets greatly affect estimates of populations living in food deserts. Measures of access to food must include travel duration and mode and supermarket food costs. PMID:22897554

  2. Uranium in the Copper King Mine, Black Hawk No. 1 Claim, Larimer County, Colorado

    Radioactive rock was discovered on the dump of the Copper King mine, sec. 8, T. 10 N., R. 72 W., Larirrier County, Colo., in the summer of 1949. The mine had been prospected intermittently for copper and zinc since 1,916, but there is no record that ore was produced. The country rock is pre-Cambrian granite containing many schist inclusions and narrow pegmatite dikes. Pitchblende disseminated in chlorite and sulfides was deposited in an obscure vein system during an intermediate stage of mineralization. This stage was preceded by biotitic alteration of amphiboles and sulfide deposition. The latest stage of mineralization is represented-by the limonitic dense quartz vein followed during mining. The uranium-bearing vein is about 2-3 feet wide and the dense quartz vein is less than 6 inches wide. Both veins are bordered by 1-3 feet of biotite- and sulfide-bearing granite and arriphibole schist. The uranium content of 26 samples taken in the mine and on the dump ranges from 0.002 to 1.40 percent. These samples contained as much as 2.97 percent copper and 5.96 percent zinc. The general outlook for further prospecting near the Copper King shaft is not favorable, because much of the 'immediately surrounding area has been thoroughly investigated without finding abnormal radioactivity. The most favorable environment for concentration of uranium minerals appears to have been in or near schist inclusions in granite, and further exploration in nearby prospects may result in the discovery of other uranium-bearing deposits. In the Copper King mine, additional exploration would aid in determining the extent of the uranium-bearing material.

  3. Tumbleweed Delta-Lower Tannehill Point Bars, geochemistry and dipmeter logs of Dickens and King Counties, Texas

    1990-02-01

    The oil-prone Tannehill sandstone trend is an extensive Eastern Shelf clastic depositional system derived from an ancient uplift located several counties away to the east-northeast of Dickens and King counties. The older 100-mi-long lower Tannehill system, preceding the upper Tannehill (Frye) system, trended east-west into King and Dickens counties, where it lies in the domain of the shallow-water-shelf delta distributary, situated between the well-documented prolific point-bar (fluvial) deposits of Baylor, Knox, and eastern King counties, and the massive nonproductive slope-mouth bar (deeper water) deposits of western Kent and western Dickens counties. The individual prolific and shallow sand bodies in the shelf distributary of Dickens and King counties are shelf delta point-bars, with some reworking. Geologists for years have erroneously played the sands and interpreted dipmeter logs in this area as fluvial point-bars. Case histories illustrate the complex stratigraphic traps of varying sizes that are formed, and the problems with dipmeter interpretations. Prospecting techniques involving subsurface geology and soil-gas geochemistry have resulted in wildcat success ratios in excess of 25% and development well success in excess of 85%. Numerous fields with proven total recoverable reserves in excess of 800,000 bbl of oil have been found over the last 10 yr. The premise central to modern-day geochemical soil gas prospecting is that very small amounts (parts per million) of light hydrocarbons move upward continuously (but not always vertically) over time from subsurface hydrocarbon reservoirs toward the ground surface, and such microseepage is detectable by modern instruments sensitive to parts per billion. Case histories illustrate that such unconventional techniques are very successful only in certain geologic provinces, and are to be integrated with subsurface geology and other conventional methods.

    Human T-cell lymphotropic virus type 2 (HTLV-2) is endemic in injection drug users (IDU), and native American populations in the Americas. Transmission is associated with high-risk injection and sexual practices. A cohort of 2561 IDU in King County, Washington completed 2 study visits over 1 y. HTLV-2 infection was detected in 190 (7.4%) of 2561 IDU, and 13 (7.8 cases per 1000 person-y) incident infections occurred during the study. Prevalent infection was associated with female gender, non-white race, longer duration as IDU, having a tattoo, combined injection of heroin and cocaine, and with serologic evidence of hepatitis B and C infection. Seroconversion was more common in women, and was associated with African American race, heterosexual identity and longer duration as IDU. In conclusion, increased risk of HTLV-2 infection was associated with non-white race, and injection drug of choice, suggesting injection networks may play an important role in transmission of HTLV-2. The high correlation of HTLV-2 infection with HCV infection suggests the major route of transmission in IDU is via injection practices. Additional studies are needed to examine the clinical manifestations of HTLV-2 infection, as well as the clinical and virological manifestations of HTLV-2/HCV coinfection. PMID:16857611

    Although most studies have concentrated on fatal residential fire injuries, which are a leading cause of fatal injuries in the United States, few investigators have examined in detail nonfatal injuries as a consequence of residential fires. This population-based study used the Washington State Fire Incident Reporting System to assess the incidence and descriptive epidemiology of fatal and nonfatal burns or respiratory tract damage resulting from unintentional residential fires. For the 2-year period 1984-85 in King County, WA, the mortality rate due to injury in a residential fire was 0.7 per 100,000 per year, and the incidence of nonfatal injuries was 5.6 per 100,000 per year. Of 17 fatalities, 59 percent of the deaths occurred at the scene of the fire. Of 128 persons with nonfatal injuries, 19 percent were hospitalized; although the 55 percent seen as outpatients and the 26 percent treated by the fire department or paramedics at the fire scene usually had minor injuries, they would not have been captured if only traditional data sources had been employed. Those injured averaged 2.8 days of restricted activity, but the range was from less than 1 day to 1 year. Injuries were more common in the households with a low socioeconomic status and among nonwhites, especially American Indians. Variation in incidence by age, sex, and source of ignition for deaths and nonfatal injuries suggests appropriate targets for future fire injury prevention programs. PMID:1641436

    OBJECTIVES. Tuberculosis has become a resurgent public health problem in the United States. Because resources are limited, control programs frequently must target populations at greatest risk. The purpose of the study was to examine risk factors for tuberculosis in adults. METHODS. In King County, Washington State, from 1988 through 1990, the characteristics of patients with tuberculosis were compared with census data, and a case-control study was conducted. Self-administered questionnaires were completed by 151 patients with active tuberculosis and 545 control subjects. RESULTS. Infection with the human immunodeficiency virus, non-White race/ethnicity, and foreign birthplace were each associated with a sixfold or greater increase in risk. Each of the following was associated with at least a doubled risk: history of selected underlying medical conditions; low weight for height; low socioeconomic status; and age 70 years or older. Men had 1.9 times the risk of women, smokers of 20 years' or more duration had 2.6 times the risk of nonsmokers, and heavy alcohol consumers had 2.0 times the risk of nondrinkers. CONCLUSIONS. Intervention targeting easily identified groups may be an effective way to reduce the incidence of tuberculosis. PMID:7977912

    From December, 1987 to September, 1990, 16 prospects within the current confines of the Lower King (Upper Pennsylvanian Cisco age) Sand Play in Concho County, Texas, were tested by several operators on locations found by various combinations of subsurface geology, reconnaissance surface radiometrics, and soil gas hydrocarbon leads A 37.5% exploratory success rate has resulted in six new field discoveries or extensions with a total exploration and development cost of less than $0.50 per barrel of proven oil reserves. The average recoverable reserves per new field discovery are estimated to be 2.6 Mbbl of oil, and the average recoverable reserves per well are estimated to be 285,000 bbl at a depth of 2200 ft. Five of the six new field discoveries were based primarily on surface geochemical data. The sixth discovery, a southeast extension to the Lonesome Dove II field, was found on the basis of subsurface geology. The Agaritta field is one of the two largest of the new field discoveries with estimated proven (producing and undeveloped) recoverable reserves of 6 Mbbl of oil as of September, 1990. Its discovery was based on a combination of (1) detailed interstitial soil gas hydrocarbon data, (2) soil magnetic susceptibility measurements, and (3) surface potassium and uranium concentrations measured by gamma-ray spectrometry applied over two leads based on reconnaissance radiometrics. What initially appeared to be two separate prospects spaced over 7000 ft apart has since developed into one large field.

    Kings Bay is an estuary on the gulf coast of peninsular Florida with a surface area of less than one square mile. It is a unique estuarine system with no significant inflowing rivers or streams. As much as 99 percent of the freshwater entering the bay originates from multiple spring vents at the bottom of the estuary. The circulation and flushing characteristics of Kings Bay were evaluated by applying SIMSYS2D, a two-dimensional numerical model. Field data were used to calibrate and verify the model. Lagrangian particle simulations were used to determine the circulation characteristics for three hydrologic conditions: low inflow, typical inflow, and low inflow with reduced friction from aquatic vegetation. Spring discharge transported the particles from Kings Bay through Crystal River and out of the model domain. Tidal effects added an oscillatory component to the particle paths. The mean particle residence time was 59 hours for low inflow with reduced friction; therefore, particle residence time is affected more by spring discharge than by bottom friction. Circulation patterns were virtually identical for the three simulated hydroloigc conditions. Simulated particles introduced in the southern part of Kings Bay traveled along the eastern side of Buzzard Island before entering Crystal River and existing the model domain. The flushing characteristics of Kings Bay for the three hydrodynamic conditions were determined by simulating the injection of conservative dye constituents. The average concentration of dye initially injected in Kings Bay decreased asymptotically because of spring discharge, and the tide caused some oscillation in the average dye concentration. Ninety-five percent of the injected dye exited Kings Bay and Crystal River with 94 hours for low inflow, 71 hours for typical inflow, and 94 hours for low inflow with reduced bottom friction. Simulation results indicate that all of the open waters of Kings Bay are flushed by the spring discharge. Reduced bottom friction has little effect on flushing.

    Objectives. We examined population-level impact on customer awareness and use and explored potential disparities in outcomes regarding the King County, Washington, regulation requiring chain restaurants to provide calorie information. Methods. We analyzed 2008 to 2010 Behavioral Risk Factor Surveillance System data from 3132 English-speaking King County residents aged 18 years and older who reported eating at a regulated chain. We used regression models to assess changes in calorie information awareness and use from prepolicy to postpolicy implementation by customer demographics, health status, and restaurant type. Results. Calorie information awareness and use increased significantly from 2008 to 2010. Unadjusted analyses indicated that the proportion who saw and used calorie information tripled, from 8.1% to 24.8%. Fully adjusted analyses confirmed significant increases. After policy implementation, White, higher income, and obese respondents had greater odds of seeing calorie information. Women, higher income groups, and those eating at a fast-food versus a sit-down chain restaurant were more likely to use this information. Conclusions. Significant increases in calorie information awareness and use following regulation support the population-wide value of this policy. However, improvements varied across race, income, and gender.

    Introduction This study investigated facilitators and barriers to adoption of an at-scene patient education program by firefighter emergency medical technicians (EMTs) in King County, Washington. Methods We consulted providers of emergency medical services (EMS) to develop a patient education pamphlet in the form of a tear-off sheet that could be attached to the EMT medical incident report. The pamphlet included resources for at-scene patient education on high blood pressure, blood glucose, falls, and social services. The program was launched in 29 fire departments in King County, Washington, on January 1, 2010, and a formal evaluation was conducted in late 2011. We developed a survey based on diffusion theory to assess 1) awareness of the pamphlet, 2) evaluation of the pamphlet attributes, 3) encouragement by peers and superiors for handing out the pamphlet, 4) perceived behavioral norms, and 5) demographic variables associated with self-reported adoption of the at-scene patient education program. The survey was completed by 822 (40.1%) of 2,047 firefighter emergency medical technicians. We conducted bivariate and multivariable analyses to assess associations between independent variables and self-reported adoption of the program. Results Adoption of the at-scene patient education intervention was significantly associated with positive evaluation of the pamphlet, encouragement from peers and superiors, and perceived behavioral norms. EMS providers reported they were most likely to hand out the pamphlet to patients in private residences who were treated and left at the scene. Conclusion Attributes of chronic disease prevention programs and encouragement from peers and supervisors are necessary in diffusion of patient education interventions in the prehospital care setting.

    The Olalla 7.5' quadrangle, which lies almost in the center of the Puget Lowland, displays the broad range of geologic environments typical of the region. The upland plain is fluted by the passage of the great continental ice sheet that last covered the area about 17,000 (14,000 radiocarbon) years ago. The plain is cut by channel deposits, both late glacial and postglacial in age, and it is cleaved even more deeply by one of the major arms of Puget Sound, Colvos Passage, which here separates the west coast of Vashon Island from the Kitsap Peninsula. Beneath the deposits of the last ice sheet is a complex sequence of older Quaternary-age sediments that extends about 400 m below the modern ground surface. These older sediments are best exposed along the shorelines and beach cliffs of Puget Sound, where wave action and landslides maintain relatively fresh exposures. The older sediments typically are compact, having been loaded by ice during one or more episodes of glaciation subsequent to their deposition. Locally these sediments are also cemented by iron and manganese oxides and hydroxides, a consequence of many tens or hundreds of thousands of years of weathering and groundwater movement. Our map is an interpretation of a 6-ft resolution lidar-derived digital elevation model combined with the geology depicted on the "Geologic map of the Olalla 7.5' quadrangle, King, Kitsap, and Pierce Counties, Washington," by Booth and Troost (2005), which was described, interpreted, and located on the 1953 1:24,000-scale topographic map of the Olalla 7.5-minute quadrangle. The original topographic base map, derived from 1951 aerial photographs, has 20-ft contours, nominal horizontal resolution of circa 40 ft (12 m), and nominal mean vertical accuracy of circa 13 ft (4 m). This new DEM has a horizontal resolution of 6 ft (2 m) and mean vertical accuracy circa 1 ft (0.3 m). The greater resolution and accuracy of the lidar DEM facilitated a much-improved interpretation of many aspects of the surficial geology, especially the distribution and relative age of landforms and the materials inferred to comprise them.

    A new Middle Permian plant assemblage from South Ash Pasture in King County, Texas, may be the youngest and is certainly the most unusual flora known from the Permian of either West Texas or adjoining north-central Texas. Found serendipitously in the evaporite-rich upper Blaine Formation (Pease River Group, Guadalupian Series), the flora is of very low diversity despite intensive collecting efforts, and the affinities of nearly all taxa are enigmatic. The most common elements are parallel-veined leaves that resemble cordaites but that could be isolated pinnules of a pinnate leaf. Gigantopterid foliage is present but not assignable to any known taxon. A single foliar conifer specimen is too incomplete for assignment. Numerous reproductive organs, however, and an abundance of axes may represent conifers. Conchostracans, palaeoniscoid fish scales, and small heteropolar coprolites also occur in the deposit, which originated as a small, claystone-dominated channel fill in a coastal plain setting.

    Wind- and current-driven flotsam, oil spills, pollutants, and nutrients, approaching the nearshore will frequently appear to slow down/park just beyond the break zone, where waves break. Moreover, the portion of these tracers that beach will do so only after a long time. Explaining why these tracers park and at what rate they reach the shore has important implications on a variety of different nearshore environmental issues, including the determination of what subscale processes are essential in computer models for the simulation of pollutant transport in the nearshore. Using a simple model we provide an explanation for the underlying mechanism responsible for the parking of tracers, not subject to inertial effects, the role played by the bottom topography, and the non-uniform dispersion which leads, in some circumstances, to the eventual landing of all or a portion of the tracers. We refer to the parking phenomenon in this environment as nearshore sticky waters.

    The stratigraphic occurrences and interpreted biostratigraphy of invertebrate fossil taxa in the upper San Joaquin Formation and lower-most Tulare Formation encountered at the Chemical Waste Management Kettleman Hills waste disposal facility on the North Dome of the Kettleman Hills, Kings County, California are documented. Significant new findings include (1) a detailed biostratigraphy of the upper San Joaquin Formation; (2) the first fossil occurrence of Modiolus neglectus; (3) distinguishing Ostrea sequens from Myrakeena veatchii (Ostrea vespertina of authors) in the Central Valley of California; (4) differentiating two taxa previously attributed to Pteropurpura festivus; (5) finding a stratigraphic succession between Caesia coalingensis (lower in the section) and Catilon iniquus (higher in the section); and (6) recognizing Pliocene-age fossils from around Santa Barbara. In addition, the presence of the bivalves Anodonta and Gonidea in the San Joaquin Formation, both restricted to fresh water and common in the Tulare Formation, confirm periods of fresh water or very close fresh-water environments during deposition of the San Joaquin Formation.

    This study examined the correlates of injury severity using police records of pedestrian-motor-vehicle collisions on state routes and city streets in King County, Washington. Levels of influence on collision outcome considered (1) the characteristics of individual pedestrians and drivers and their actions; (2) the road environment; and (3) the neighborhood environment. Binary logistic regressions served to estimate the risk of a pedestrian being severely injured or dying versus suffering minor or no injury. Significant individual-level influences on injury severity were confirmed for both types of roads: pedestrians being older or younger; the vehicle moving straight on the roadway. New variables associated with increased risk of severe injury or death included: having more than two pedestrians involved in a collision; and on city streets, the driver being inebriated. Road intersection design was significant only in the state route models, with pedestrians crossing at intersections without signals increasing the risk of being injured or dying. Adjusting for pedestrians' and drivers' characteristics and actions, neighborhood medium home values and higher residential densities increased the risk of injury or death. No other road or neighborhood environment variable remained significant, suggesting that pedestrians were not safer in areas with high pedestrian activity. PMID:21094292

    Trace element and major ion concentrations were measured in water samples collected monthly between March 1985 and March 1986 at the MD-1 pumping station at the Tulare Lake Drainage District evaporation ponds, Kings County, California. Samples were analyzed for selected pesticides several times during the year. Salinity, as measured by specific conductance, ranged from 11,500 to 37,600 microsiemens/centimeter; total recoverable boron ranged from 4,000 to 16,000 micrg/L; and total recoverable molybdenum ranged from 630 to 2,600 microg/L. Median concentrations of total arsenic and total selenium were 97 and 2 microg/L. Atrazine, prometone, propazine, and simazine were the only pesticides detected in water samples collected at the MD-1 pumping station. Major ions, trace elements, and selected pesticides also were analyzed in water and bottom-sediment samples from five of the southern evaporation ponds at Tulare Lake Drainage District. Water enters the ponds from the MD-1 pumping station at pond 1 and flows through the system terminating at pond 10. The water samples increased in specific conductance (21,700 to 90,200 microsiemens/centimeter) and concentrations of total arsenic (110 to 420 microg/L), total recoverable boron (12,000 to 80,000 microg/L) and total recoverable molybdenum (1,200 to 5,500 microg/L) going from pond 1 to pond 10, respectively. Pesticides were not detected in water from any of the ponds sampled. Median concentrations of total arsenic and total selenium in the bottom sediments were 4.0 and 0.9 microg/g, respectively. The only pesticides detected in bottom sediment samples from the evaporation ponds were DDD and DDE, with maximum concentration of 0.8 microg/kilogram. (Author 's abstract)

    Pediatric asthma is a growing public health issue, disproportionately affecting low-income people and people of color. Exposure to indoor asthma triggers plays an important role in the development and exacerbation of asthma. We describe the implementation of the Seattle-King County Healthy Homes Project, a randomized, controlled trial of an outreach/education intervention to improve asthma-related health status by reducing exposure to allergens and irritants in the home. We randomly assigned 274 low-income children with asthma ages 4-12 to either a high- or a low-intensity group. In the high-intensity group, community health workers called Community Home Environmental Specialists (CHES) conducted initial home environmental assessments, provided individualized action plans, and made additional visits over a 12-month period to provide education and social support, encouragement of participant actions, provision of materials to reduce exposures (including bedding encasements), assistance with roach and rodent eradication, and advocacy for improved housing conditions. Members of the low-intensity group received the initial assessment, home action plan, limited education during the assessment visit, and bedding encasements. We describe the recruitment and training of CHES and challenges they faced and explain the assessment and exposure reduction protocols addressing dust mites, mold, tobacco smoke, pets, cockroaches, rodents, dust, moisture, and toxic or hazardous chemicals. We also discuss the gap between the practices recommended in the literature and what is feasible in the home. We accomplished home interventions and participants found the project very useful. The project was limited in resolving structural housing quality issues that contributed to exposure to indoor triggers. PMID:11929743

    Ocean waves near shore impact public safety, commerce, navigation, and, of course recreation. Predicting these waves has driven efforts to model them for more than two decades. This module introduces forecasters to different nearshore wave models, including phase-resolving and 1- and 2-dimensional spectral models. It describes the processes that wave models simulate, the assumptions they make, the initial and boundary conditions required to run the models, and potential sources of error in model forecasts. While focusing on SWAN, the module also examines the Navy Standard surf Model and Bouss-2D.

  4. Soil chemistry and ground-water quality of the water-table zone of the surficial aquifer, Naval Submarine Base Kings Bay, Camden County, Georgia, 1998 and 1999

    2002-01-01

    In 1998, the U.S. Geological Survey, in cooperation with the U.S. Department of the Navy, began an investigation to determine background ground-water quality of the water-table zone of the surficial aquifer and soil chemistry at Naval Submarine Base Kings Bay, Camden County, Georgia, and to compare these data to two abandoned solid- waste disposal areas (referred to by the U.S. Navy as Sites 5 and 16). The quality of water in the water-table zone generally is within the U.S. Environmental Protection Agency (USEPA) drinking-water regulation. The pH of ground water in the study area ranged from 4.0 to 7.6 standard units, with a median value of 5.4. Water from 29 wells is above the pH range and 3 wells are within the range of the USEPA secondary drinking-water regulation (formerly known as the Secondary Maximum Contaminant Level or SMCL) of 6.5 to 8.5 standard units. Also, water from one well at Site 5 had a chloride concentration of 570 milligrams per liter (mg/L,), which is above the USEPA secondary drinking-water regulation of 250 mg/L. Sulfate concentrations in water from two wells at Site 5 are above the USEPA secondary drinking-water regulation of 250 mg/L. Of 22 soil-sampling locations for this study, 4 locations had concentrations above the detection limit for either volatile organic compounds (VOCs), base-neutral acids (BNAs), or pesticides. VOCs detected in the study area include toluene in one background sample; and acetone in one background sample and one sample from Site 16--however, detection of these two compounds may be a laboratory artifact. Pesticides detected in soil at the Submarine Base include two degradates of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT): 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane (4,4'-DDD) in one background sample, 1,1-dichloro-2,2-bis(p-chlorophenyl)ethene (4,4'-DDE) in one background sample and one sample from Site 16; and dibenzofuran in one sample from Site 16. BNAs were detected in one background sample and in two samples from Site 16. Hypothesis testing, using the Wilcoxon rank-sum test (also known as the Mann-Whitney test), indicates no statistical difference between ground-water constituent concentrations from Sites 5 and 16, and background concentrations. Hypothesis testing, however, indicates the concentration of barium in background ground-water samples is greater than in ground-water samples collected at Site 16.

  5. The Nearshore Canyon Experiment

    2002-12-01

    Observations collected in Fall 2003 during the Nearshore Canyon Experiment (NCEX) will be used to test hypotheses about the effect of complex continental-shelf bathymetry on surface gravity waves and on wave-driven circulation. Refraction, diffraction, reflection, scattering, and trapping by abrupt shelf bathymetry can result in dramatic alongshore variations in wave height and direction. Onshore of the irregular bathymetry, alongcoast changes in breaking waves can force complicated circulation, including alongshore flows that reverse direction across the surf zone and along the shoreline, and strong offshore-directed rip currents that may be an important mechanism for transport of water, sediment, and pollution between the surf zone and inner shelf. Observations for NCEX will be obtained along the southern California coast near two steep submarine canyons (separated alongshore by a few km) that cross the shelf from about 300-m water depth to just seaward of the surfzone near Black's Beach (famous for large waves) and La Jolla Shores (well known as a calm area with small waves). Frequency-directional spectra of incident waves estimated from observations offshore of the canyons will be used to initialize models that predict the effect of the canyons on infragravity waves, swell, sea, and wave-driven circulation. Model predictions will be tested with observations from alongshore arrays deployed near, between, and onshore (including the surf and swash zones) of the canyons. Arrays also will be deployed to investigate wave reflection and scattering from the steep canyon walls, and cross-shore changes in surf and swash zone circulation. Additional instrumentation will be used to study alongcoast changes in wave breaking and set-up, details of surface currents in the surf and swash, and breaking-induced turbulence and dissipation. The NCEX instrument arrays will be designed in collaboration with modelers, and near-real time data will be used to initialize and test model predictions. In addition, model forecasts will be used to guide placement of movable sensors, allowing predictions of nearshore waves and currents to be tested during the observational period.

    The author has identified the following significant results. Remote sensor aircraft flights took place simultaneously with ERTS-1 overpasses at the San Francisco, Monterey Bay, and Santa Barbara test cells. The cameras and scanners used were configured for detecting suspended sediment and for maximum water penetration. The Ektachrome/Wratten 12 photographs which were intentionally overexposed 1-1/2 stops were found to show the most extensive sediment transport detail. Minus blue/K 2 photographs illustrate nearshore underwater bottom detail including the head of the Mugu submarine canyon. The EMSIDE 9 channel scanner was employed to classify and differentiate suspended sediment, oil, kelp, and other materials found in the nearshore area. Processing of bulk ERTS-1 computer compatible tapes was utilized to enhance and analyze nearshore sediments. This technique was most successful in enhancing subtle nearshore features found to be faint or invisible on prints made from the supplied negatives. In addition to this continuing computer process, an effort was initiated to interface density values from the bulk tapes into contouring and mapping software.

    The author has identified the following significant results. This report contains the techniques used for enhancing and analyzing nearshore processes from ERTS-1 and aircraft data. Four California nearshore sites are used as test cells including the San Francisco area, Monterey Bay, Santa Barbara Channel, and Los Angeles area. Techniques used for analyzing the test cells included direct photographic processing, computer compatible tape gain change enhancement, discrete point density analysis and plotting, and densitometer enhancement. Using these methods, it is possible to measure the seaward extent of the suspended sediment transport and to differentiate sediment levels within the individual sediment lobes. The movement of riverine discharged suspensates and coastal sediments by currents was an intricate part of the sediment transport analysis. The larger estuaries in the test cell areas were also studied for flushing characteristics.

    The Wyckoff/Eagle Harbor site is a National Priorities List (NPL) site located on the east side of Bainbridge Island, Kitsap County, Washington. The harbor has become contaminated with heavy metals, polychlorinated biphenyls (PCBs), and polynuclear aromatic hydrocarbons (PAHs) from the many years of ship repair and painting as well as from the application of creosote, pentachlorophenol, and other wood preservatives to pilings. The Remedial Investigation and Feasibility Study (RI/FS) states that the major human health concern is consumption of clam meat contaminated with PAHs. The public health assessment has determined that exposure to contaminants found in Eagle Harbor sediments, shellfish, fish, and crab is a health hazard for those people who ignore warnings.

    The shallow waters of the nearshore ocean are popular, dynamic, and often hostile. Prediction in this domain is usually limited less by our understanding of the physics or by the power of our models than by the availability of input data, such as bathymetry and wave conditions. It is a challenge for traditional in situ instruments to provide these inputs with the appropriate temporal or spatial density or at reasonable logistical or financial costs. Remote sensing provides an attractive alternative. We discuss the range of different sensors that are available and the differing physical manifestations of their interactions with the ocean surface. We then present existing algorithms by which the most important geophysical variables can be estimated from remote sensing measurements. Future directions and opportunities will depend on expected developments in sensors and platforms and on improving processing algorithms, including data assimilation formalisms. PMID:22809186

The primary duty of the ancient “crowner” or “King's man” was to support the interests of the King of England by investigating violent deaths. The modern counterpart of this royal officer has a much broader range of duties in the interests of justice and the state. Not only do today's coroners act as “ombudsmen for the dead”, but they also are becoming increasingly involved in medico-legal investigations of service to the living. PMID:21263903

  11. Microwave radar observations of nearshore ocean dynamics

    NASA Astrophysics Data System (ADS)

    Farquharson, Gordon

    2005-12-01

    The relationship between microwave imaging radar measurements of the nearshore ocean region and nearshore dynamics is studied. Normalized radar cross section and Doppler velocity are estimated from radar measurements of nearshore waves at near-grazing angles. Radar scattering is classified using joint histograms of radar cross section and Doppler velocities. Scattering in these distributions is investigated through comparisons with theoretical wave predictions, video particle image velocimetry (PIV), and in situ acoustic Doppler velocimeter (ADV) measurements. This analysis shows that shoaling and breaking waves measured through radar grating lobes significantly affect Doppler velocities near the edges of the images and also scattering from the back faces of waves. Doppler velocities from breaking waves are found to agree well with wave phase velocity predictions in the surf zone (the rms difference is 0.14 m/s), and large radar cross section features are correlated with breaking waves and the motion of surf-zone bores in video imagery. Differences in inter-bore velocities are expected, since the measurements are not collocated. However; Doppler inter-bore velocities are found to correlate well with fluid velocities (the correlation coefficient is 0.65), but are offset by around 0.8 m/s. This offset may be due to a combination of the Bragg wave phase velocities, radar sensitivity to short wavelength waves in the nearshore which is limited by the spatial resolution of the radar, and inherent biasing of Doppler velocities towards velocities of large NRCS scattering. In low-wind conditions, radar measurements of the nearshore show patches of increased backscatter. Animation of sequences of the images shows movement of these patches. A feature-tracking algorithm based on PIV is presented to quantify the velocities of the observed features. The nature of the patches is also investigated through comparison with video images. It is concluded that the patches of backscatter are due to low-grazing angle scattering from streaks of foam, however contributions from mechanically-generated surface roughness are not ruled out. Comparisons between surface velocities derived from the feature-tracking algorithm and subsurface velocities measured by in situ current meters show best agreement for sensors beyond the surf zone. It is concluded that the estimated velocity fields are related to nearshore flows such as wave-induced cell circulations and longshore currents.

    1983-01-01

    To predict the effects of increased nutrient loading on nearshore phytoplankton populations in northern Lake Huron, we collected phytoplankton from a small, nearshore water intake at Hammond Bay four times per week from August 1973 to July 1975. Phytoplankton density, taxonomic composition, and biomass in the nearshore waters followed predictable, seasonal fluctuations during each of two 12-month periods. The density of total phytoplankton was high (450600 cells/mL) in June and low (60 to 210 cells/mL) from January to April each year. The mean annual composition of the phytoplankton assemblage by number for the study period was 33% cryptomonads, 24% diatoms, 16% chrysophytes, 16% blue-green algae, and 10% green algae. Phytoplankton biomass was low through each year (range, 0.09 to 0.66 g/m3), resembling values previously reported from Lake Superior. Pennate diatoms contributed 60 to 80% of the total biomass from December to April and in July. Phytoflagellates consisting of chrysophytes and cryptomonads accounted for 35% of the biomass throughout the 2-year study.

  15. An evaluation of effects of groundwater exchange on nearshore habitats and water quality of western Lake Erie

    USGS Publications Warehouse

    Haack, Sheridan K.; Neff, Brian P.; Rosenberry, Donald O.; Savino, Jacqueline F.; Lundstrom, Scott C.

    2005-01-01

    Historically, the high potentiometric surface of groundwater in the Silurian/Devonian carbonate aquifer in Monroe County, MI resulted in discharge of highly mineralized, SO4-rich groundwater to the Lake Erie shoreline near both Erie State Game Area (ESGA) and Pointe Mouillee State Game Area (PMSGA). Recently, regional groundwater levels near PMSGA have been drawn down as much as 45 m below lake level in apparent response to quarry dewatering. From August to November of 2003, we conducted preliminary studies of groundwater flow dynamics and chemistry, shallow lake water chemistry, and fish and invertebrate communities at both sites. Consistent with regional observations, groundwater flow direction in the nearshore at ESGA was upward, or toward Lake Erie, and shallow nearshore groundwater chemistry was influenced by regional groundwater chemistry. In contrast, at PMSGA, the groundwater flow potential was downward and lake water, influenced by quarry discharge seeping downward into nearshore sediments, produced a different lake and shallow groundwater chemistry than at ESGA. Although the invertebrate and young fish community was similar at the two sites, taxonomic groups tolerant of degraded water quality were more prevalent at PMSGA. Sensitive taxa were more prevalent at ESGA. We propose a conceptual model, based on well-described models of groundwater/seawater interaction along coastal margins, to describe the interconnection among geologic, hydrologic, chemical, and biological processes in the different nearshore habitats of Lake Erie, and we identify processes that warrant further detailed study in the Great Lakes.

    2006-01-01

    A process-based model is compared with field measurements to test and improve our ability to predict nearshore morphological change at seasonal time scales. The field experiment, along the dissipative beaches adjacent to Grays Harbor, Washington USA, successfully captured the transition between the high-energy erosive conditions of winter and the low-energy beach-building conditions typical of summer. The experiment documented shoreline progradation on the order of 20 m and as much as 175 m of onshore bar migration. Significant alongshore variability was observed in the morphological response of the sandbars over a 4 km reach of coast. A detailed sensitivity analysis suggests that the model results are more sensitive to adjusting the sediment transport associated with asymmetric oscillatory wave motions than to adjusting the transport due to mean currents. Initial results suggest that alongshore variations in the initial bathymetry are partially responsible for the observed alongshore variable morphological response during the experiment.

    This image from the Mars Exploration Rover Opportunity's panoramic camera shows one octant of a larger panoramic image which has not yet been fully processed. The full panorama, dubbed 'Lion King' was obtained on sols 58 and 60 of the mission as the rover was perched at the lip of Eagle Crater, majestically looking down into its former home. It is the largest panorama yet obtained by either rover. The octant, which faces directly into the crater, shows features as small as a few millimeters across in the field near the rover arm, to features a few meters across or larger on the horizon.

    The full panoramic image was taken in eight segments using six filters per segment, for a total of 558 images and more than 75 megabytes of data. This enhanced color composite was assembled from the infrared (750 nanometer), green (530 nanometer), and violet (430 nanometer) filters. Additional lower elevation tiers were added relative to other panoramas to ensure that the entire crater was covered in the mosaic.

  5. A real-time nearshore wave and current prediction system

    Allard, Richard; Dykes, James; Hsu, Y. L.; Kaihatu, James; Conley, Daniel

    A nearshore wave, tide and current prediction system was demonstrated during the MREA04 Trial in the Portuguese coastal waters near Pinheiro da Cruz during the early spring of 2004. Daily forecasts of regional scale wave and tidal information and nearshore waves and currents were generated in DIOPS utilizing a suite of regional and nearshore models forced with data from meteorological and oceanographic production centers. A limited beach experiment was conducted with three Nortek current meters deployed in the surf zone and a video imagery system to generate 10-min time exposures used to identify the locations of wave breaking. In this study, Delft3D, a coastal hydrodynamic modeling system, capable of simulating hydrodynamic processes due to waves, tides, rivers, winds and coastal currents, is used to predict the nearshore wave and longshore currents near Pinheiro da Cruz. The nearshore bathymetry used in this study was based on LIDAR data collected in February 2000. Delft3D shows mixed results when compared with the measured wave height and nearshore currents. Improved Delft3D results can be achieved in the future if migrating sand bars can be measured and included in the modeling.

  6. A spatial framework for representing nearshore ecosystems

    NASA Astrophysics Data System (ADS)

    Gregr, Edward J.; Lessard, Joanne; Harper, John

    2013-08-01

    The shallow, coastal regions of the world's oceans are highly productive ecosystems providing important habitat for commercial, forage, endangered, and iconic species. Given the diversity of ecosystem services produced or supported by this ecosystem, a better understanding of its structure and function is central to developing an ecosystem-based approach to management. However this region - termed the ‘white strip' by marine geologists because of the general lack of high-resolution bathymetric data - is dynamic, highly variable, and difficult to access making data collection challenging and expensive. Since substrate is a key indicator of habitat in this important ecosystem, our objective was to create a continuous substrate map from the best available bottom type data. Such data are critical to assessments of species distributions and anthropogenic risk. Using the Strait of Georgia in coastal British Columbia, Canada, as a case study, we demonstrate how such a map can be created from a diversity of sources. Our approach is simple, quantitative, and transparent making it amenable to iterative improvement as data quality and availability improve. We evaluated the ecological performance of our bottom patches using observed shellfish distributions. We found that observations of geoduck clam, an infaunal species, and red urchins, a species preferentially associated with hard bottom, were strongly and significantly associated with our soft and hard patches respectively. Our description of bottom patches also corresponded well with a more traditional, morphological classification of a portion of the study area. To provide subsequent analyses (such as habitat models) with some confidence in the defined bottom type values, we developed a corresponding confidence surface based on the agreement of, and distance between observations. Our continuous map of nearshore bottom patches thus provides a spatial framework to which other types of data, both abiotic (e.g., energy) and biotic, can be attached. As more data are associated with the bottom patches, we anticipate they will become increasingly useful for representing and developing species-habitat relationships, ultimately leading to a comprehensive representation of the nearshore ecosystem.

  8. Impacts of Cyclone Yasi on nearshore, terrigenous sediment-dominated reefs of the central Great Barrier Reef, Australia

    NASA Astrophysics Data System (ADS)

    Perry, C. T.; Smithers, S. G.; Kench, P. S.; Pears, B.

    2014-10-01

    Tropical Cyclone (TC) Yasi (Category 5) was a large (~ 700 km across) cyclone that crossed Australia's Queensland coast on the 3rd of February 2011. TC Yasi was one of the region's most powerful recorded cyclones, with winds gusting to 290 km/h and wave heights exceeding 7 m. Here we describe the impacts of TC Yasi on a number of nearshore, turbid-zone coral reefs, that include several in the immediate vicinity of the cyclone's landfall path (King Reef, Lugger Shoal and Dunk Island), as well as a more distally located reef (Paluma Shoals) ~ 150 km to the south in Halifax Bay. These reefs were the focus of recent (between 2006 and 2009) pre-Yasi studies into their geomorphology, sedimentology and community structure, and here we discuss data from a recent (August 2011) post-Yasi re-assessment. This provided a unique opportunity to identify and describe the impacts of an intense tropical cyclone on nearshore reefs, which are often assumed to be vulnerable to physical disturbance and reworking due to their poorly lithified framework. Observed impacts of TC Yasi were site specific and spatially highly heterogeneous, but appear to have been strongly influenced by the contemporary evolutionary stage and ecological make-up of the individual reefs, with site setting (i.e. exposure to prevailing wave action) apparently more important than proximity to the landfall path. The most significant ecological impacts occurred at King Reef (probably a result of freshwater bleaching) and at Paluma Shoals, where widespread physical destruction of branched Acropora occurred. New coral recruits are, however, common at all sites and colony re-growth clearly evident at King Reef. Only localised geomorphic change was evident, mainly in the form of coral fracturing, rubble deposition, and sediment movement, but again these impacts were highly site specific. The dominant impact at Paluma Shoals was localised storm ridge/shingle sheet deposition, at Lugger Shoal major offshore fine sediment flushing, and at Dunk Island major onshore coarse sand deposition. There was little geomorphic change evident at King Reef. Thus whilst small-scale and taxa specific impacts from Cyclone Yasi are clearly evident, geomorphological changes appear minor and ecological impacts highly variable between sites, and there is no observed evidence for major reef structural change. The study suggests that the vulnerability of reefs to major physical disturbance events can be extremely site specific and determined by interacting factors of location relative to storm path and pre-event geomorphology and ecology.

    The Commencement Bay Nearshore/Tideflats project site is located in Pierce County, Washington and includes approximately 12 square miles of shallow water, shorelines, tideflats, and upland industrial/commercial sections in and around the City of Tacoma. Since the late 1800s, industrialization of the Commencement Bay area has resulted in many metals, such as lead and arsenic, and organic compounds, such as polychlorinated bipheny (PCBs) and polynuclear aromatic hydrocarbon (PAHs), being released into the marine environment. The waterways and the shoreline are impacted by over 400 potential pollutant sources, including storm drains, pulp mills, chemical plants, and oil refineries. Levels of contaminants in bottom fish and shell fish pose a potential public health concern for those consuming local seafood. Levels of contaminants in sediment, surface water, soil, and air may also pose potential public health concerns for remedial workers and those individuals involved in recreational and commercial activities at the site.

  20. California nearshore processes - ERTS 1. [coastal currents and sediments

    NASA Technical Reports Server (NTRS)

    Steller, D. D.; Pirie, D. M.

    1974-01-01

    The detectability of many nearshore processes from ERTS is made possible due to the suspended sediment present in the coastal waters. From viewing and analyzing the California coastal imagery collected during the last year and a half, the overall current patterns and their changes have become evident. It is now possible to map monthly and seasonal changes that occur throughout the year. The original objectives of detecting currents, sediment transport, estuaries and river discharge have now been expanded to include the use of ERTS information in operational problems of the U.S. Army Corps of Engineers. This incorporates the detected nearshore features into planning and organizing shore protection facilities.

  1. Geological development of the Lonesome Dove II King Sand field

    SciTech Connect

    Powers, D.H.; Watters, G. (Marshall and Winston, Inc., Midland, TX (United States))

    1992-04-01

    In March of 1989, Marshall and Winston, Inc., drilled Petro-West Corporation's Brady Creek prospect, 5 mi southwest of Eden, Concho County, Texas, along the southern part of the eastern shelf of the Permian basin. The prospect was drilled on the basis of a subsurface, geological anomaly mapped on the lower King Sandstone. The anomaly was confirmed and enhanced by soil gas geochemistry. The McMurtrey No.1 well encountered 38 ft of sandstone, and has an estimated potential of 79 BOPD (pumping). The lower King Sandstone at Lonesome Dove II field is part of a larger northeast-southwest-trending Cisco depositional system. Data from subsequent drilling at Lonesome Dove II (including two conventional cores, samples, sidewall cores, dipmeters, and electric logs) indicates that the lower King Sandstone may have been deposited during a regressive cycles of fluvial-deltaic sedimentation. Characteristics of both fluvial point bar and distributary channel facies have been noted and the development of a distributary model of deposition led to the extension of the field beyond the limits of the original subsurface and geochemical picture. The presence of two or more separate channels or channel systems is indicated by isopach maps and by significant oil gravity, field pressure, and grain size differences. These channel systems may have been deposited on a relatively flat-lying deltaic plain as indicated by cross sections showing only slight channel downcutting.

  2. Congratulations to Carey King

    NASA Astrophysics Data System (ADS)

    Hall, Charles A. S.

    2012-03-01

    I first came across Carey King when, out of the blue, he invited me to a special session of the annual meeting of the American Association for the Advancement of Science (the largest and most prestigious US scientific meeting) where he was developing a special session on energy return on investment (EROI). At that meeting and since, I have found Carey to be a refreshing new colleague, extremely intelligent, very knowledgeable about many diverse aspects of energy and other things, able to take criticism and to dish it out, and very ambitious, which is mostly a good thing. He is becoming a leader in thinking about EROI and its implications, and I am delighted to see him honored by Environmental Research Letters. This is important because in the US, there is little insight about energy or, especially, its potential physical limitations except when gas prices increase. There is also little awareness of the very strong historical connection in both the US and the world between increased affluence and increased use of energy, especially petroleum. It is not understood by all that many of the economic problems we have now (such as the budgetary problems faced by most of our State governments, pension plans and universities) have substantial origin in the fact that oil and other energy production no longer increase reliably year after year, as they once did (Murphy and Hall 2011). Many economists have argued in the past that energy is not important because it constituted only 5 per cent or so of GDP, or because they believe that market forces and innovations will substitute for any shortage (e.g. Barnett and Morse 1963, Passell et al 1972, Solow 1974, Denison 1989). One problem with that view is that if you remove that five per cent the economy comes to a dead stop, as Cuba found out in 1989 when Russia removed its oil subsidy. Additionally if that five per cent goes up to 10 or 15 per cent, as it did in the early 1980s, and again in 2008, recession steps in (Murphy and Hall 2011). In fact, the US economy and our energy use increased almost lockstep from 1900 until 1984 (Cleveland et al 1984). The economy has grown more rapidly than energy use since 1984. Most economists think that this is due to our cleverness at increasing efficiency, but Robert Kaufmann (2004) and others find that instead most of the increase has been due to, essentially, the outsourcing of our heavy industry (think steel imported from Korea or Brazil, petroleum refined in Trinidad etc). An additional issue is that there is considerable evidence (e.g. Shadow Government Statistics) that the official US government inflation corrections have been deliberately underestimated since about 1985. If this is true then GDP growth has been exaggerated and there has been little or no increase in efficiency. Thus our gain in actual national energy efficiency is probably much less than most economists believe, and may be close to zero. Obviously some few of us think a great deal about energy, and for those who are willing to undertake some personal research (for example on the ASPO (aspo-usa.com) or The Oil Drum (www.theoildrum.com) websites), there is much to be concerned about. First on the list of concerns is 'peak oil'; the concept that there comes a time over the life cycle of the extraction of a non-renewable resource when there will be maximum production. This concept, derived by geologist M K Hubbert in the 1950s, assumes that this peak will occur when roughly 50 per cent of the resource has been exploited. Hubbert famously predicted in 1955 that this would occur for the United States in 1970. Initially he was derided by most in the oil industry, but in fact peak oil for the US did occur in 1970, just as he had predicted. Oil production has declined essentially every year since then. 'Peak oil' has now occurred for something like three quarters of all oil producing nations, although not yet for most of the largest producers. Second on my list of energy concerns is declining EROI. EROI is a term I had developed in the early 1980s based on the net energy concepts of

  3. Multiple Sand Bar Formation in the Nearshore Zone

    NASA Astrophysics Data System (ADS)

    Absalonsen, L.; Dean, R.

    2011-12-01

    Sand bars are prominent features on many beaches, and can represent a major source of morphologic change in the cross-shore profile. The breaking waves are concentrated at the bar crests, resulting in reduced energy in the landward zone. Bars respond to different wave energy conditions, slowly moving shoreward with low waves and rapidly moving offshore with higher waves. However the formation and evolution of bars on multiple barred beaches is poorly understood. The presentation will describe preliminary efforts to predict the location of sand bars in the cross-shore profile, to quantify the number of sand bars under different hydrodynamic conditions and to illustrate the capability to predict profile evolution. A wave height transformation model (Dally model), a sediment transport model and conservation model are applied. The two-dimensional wave height model establishes wave height across the nearshore zone due to wave shoaling and breaking, including wave setup and bottom stress. This model utilizes two threshold values to predict the breaking position and after breaking, in the deeper water of the bar trough, the position where the waves stabilize and start to shoal again (stability criterion). Both criteria depend on the local water depth. At present, the sediment transport model consists of three components. First, the moment of momentum due to breaking waves is transferred to the bottom as a seaward shear stress concentrated somewhat landward of the bar crest. Secondly, the onshore shear stress is due to the nonlinearity of the breaking waves. Finally, the onshore transport is magnified by the proximity of turbulence to the bottom in shallow water. This model is of the "open loop" type, thus there is no guarantee of convergence to a stable profile. The capability of the model to predict bar locations on an actual profile is illustrated as follows. A profile consisting of three bars is selected from Volusia County along the northeast Florida Atlantic coastline. In the first step, the inshore and middle bars were smoothed leaving only the outer bar. The model was applied with an offshore wave height of 1.5 m which shoaled to 2.1 m where it broke on the outer bar. It was determined that the breaking on the outer bar and reformation and breaking landward of the outer bar could predict the approximate location of the middle bar. The process is repeated, now inserting the actual middle bar to verify that the model can predict the approximate correct location of the inner bar. The results obtained from this simulation and other profiles with two and three bars from Volusia County, showed similar results and are promising for the application of this model to calculate the number of inner bars. A second illustration of the model is a comparison with data of profile evolution from large wave tank experiments. Comparison of predicted profiles by the model with the measured profiles will be presented for various times during the profile evolution.

    The author has identified the following significant results. Large scale sediment plumes from intermittent streams and rivers form detectable seasonal patterns on ERTS-1 imagery. The ocean current systems, as plotted from three California coast ERTS mosaics, were identified. Offshore patterns of sediment in areas such as the Santa Barbara Channel are traceable. These patterns extend offshore to heretofore unanticipated ranges as shown on the ERTS-1 imagery. Flying spot scanner enhancements of NASA tapes resulted in details of subtle and often invisible (to the eye) nearshore features. The suspended sediments off San Francisco and in Monterey Bay are emphasized in detail. These are areas of extremely changeable offshore sediment transport patterns. Computer generated contouring of radiance levels resulted in maps that can be used in determining surface and nearsurface suspended sediment distribution. Tentative calibrations of ERTS-1 spectral brightness against sediment load have been made using shipboard measurements. Information from the combined enhancement and interpretation techniques is applicable to operational coastal engineering programs.

While each site has its own personality and delivery style, they all make an attempt to break out teacher and/or student resources by grade level. In some cases (Science, Social Studies) this is done through a search interface. In others (Language Arts, Mathematics) it is done via a browsable interface. It is this categorization, plus the fact that resources are selected, evaluated, and annotated by teachers, that is the both the power and unifying theme of the sites. Depending on the site, assessment and teacher development sections may also be available.

  3. Dynamic ice-wallow relief of northern Alaska's nearshore.

    1982-01-01

    Contour maps with 0.5m depth interval were prepared for a small area seaward of Reindeer Island, a barrier island in the Beaufort Sea, Alaska, by repeated surveys with very accurate navigation and very close trackline spacing. The maps reveal numerous closed depressions and mounds, presumably related to grounded ice floes common in the area year round. These bedforms represent erosion and deposition caused by: a) intensified flow around stationary ice floes serving as obstacles and b) pulsating currents generated by vertical oscillations or rocking motions of grounded floes in a seaway. Because sediment transport occurs around the ice, not where it directly touches the sea floor, the depressions are much larger than the base of the acting floes. Ice-wallow bedforms, are characteristic of arctic nearshore regions with non-cohesive sediments. The bedforms studied here are highly active and must be considered in planning nearshore construction activities. -from Authors

    2012-07-01

    We observed transient stratification and mixing events associated with nearshore internal bores in southern Monterey Bay using an array of instruments with high spatial and temporal resolution. The arrival of the bores is characterized by surging masses of dense (cold) water that tend to stratify the water column. The bore is followed by a gradual drop in the temperature throughout the water column over several hours (defined here as the bore period) until a sharp warm-front relaxation, followed by high frequency temperature fluctuations, returns the column back to nearly its original state (defined here as the mixing period). Mixing periods revealed increased temperature variance at high frequencies (? > N¯), as well as a greater percentage of events where dynamic instabilities may be present (Ri< 0.25), suggesting active mixing of the stratified water column. Turbulent dissipation rates in the stratified interior during the mixing period, estimated using the technique of isopycnal slope spectra, revealed mean values the same order of magnitude as near-bed bottom-generated turbulence. Observations indicate that local shear-produced turbulent kinetic energy by the warm front relaxations dominates mixing in the stratified interior. The non-canonical nature of these bore and relaxation events is also investigated with a numerical model, and the dynamics are shown to depend on the internal Iribarren number. Our results suggest that nearshore internal bores interacting with local bathymetry dramatically alter local dynamics and mixing in the nearshore with important ecological implications.

    An approach was developed for using video imagery to quantify, in terms of both spatial and temporal dimensions, a number of naturally occurring (nearshore) physical processes. The complete method is presented, including the derivation of the geometrical relationships relating image and ground coordinates, principles to be considered when working with video imagery and the two-step strategy for calibration of the camera model. The techniques are founded on the principles of photogrammetry, account for difficulties inherent in the use of video signals, and have been adapted to allow for flexibility of use in field studies. Examples from field experiments indicate that this approach is both accurate and applicable under the conditions typically experienced when sampling in coastal regions. Several applications of the camera model are discussed, including the measurement of nearshore fluid processes, sand bar length scales, foreshore topography, and drifter motions. Although we have applied this method to the measurement of nearshore processes and morphologic features, these same techniques are transferable to studies in other geophysical settings.

  12. Martin Luther King Assassination Conspiracy Verdict

    Thirty-five years ago, on December 10, 1964, Dr. Martin Luther King Junior received the prestigious Nobel Peace Prize. This week, Dr. King has again been very much in the news. On December 9th, a Memphis jury handed down a verdict that the 1968 assassination of the civil rights leader was a conspiracy rather than the act of lone gunman James Earl Ray. The verdict was the conclusion of a wrongful death suit brought by King's family against businessman Lloyd Jowers, who admitted on network television in 1993 that he was given $100,000 to arrange King's murder. King's relatives have long argued that the crime was never fully examined by the courts, and brought the lawsuit in an attempt to learn the truth. The family accepted a token settlement of $100 in damages from Jowers.

  16. Towards an Operational Nearshore Wave Data Assimilation System

    NASA Astrophysics Data System (ADS)

    Veeramony, J.; Orzech, M.; Ngodock, H. E.; Flampouris, S.

    2012-12-01

    For Navy operations, the model used for wave predictions in the nearshore is SWAN, which solves the spectral action balance equation to estimate the wave state. Boundary conditions for local (nearshore) model domains are generally obtained from regional model simulations that use either SWAN or WAVEWATCH III, which in turn gets boundary conditions from global simulations with WAVEWATCH III forced by the meteorological models. Inaccuracies in meteorological forcing and the coarse grid resolutions for the global model can lead to significant errors in SWAN's spectral estimates, particularly in shallow water. To improve the model's performance, especially for the small nearshore domains, we have developed a 4DVAR data assimilation system based on a tangent linear code and the corresponding adjoint from the numerical SWAN model. The system utilizes point measurements of 2D wave spectra, such as from a wave buoy, to improve the solution in the whole domain. Given a set of observations measured at different times and locations in the model domain, the assimilation system minimizes a cost function (representing overall error between the model and observations) and generates corrected boundary and initial conditions that optimize the fit of SWAN's output to the measurements. In addition to time dependence, the system accounts for nonlinear triad and quadruplet interactions, depth-limited breaking, wind forcing, bottom friction, and whitecapping as well as the influence of currents on waves. This presentation will review the current status of the system using simulations with data from Duck, North Carolina and the 2012 RIMPAC exercises held by the Commander, US Pacific Fleet in and around the Hawaiian Islands. Examples shown will include analysis of effects of using different background fields, and of assimilating different instruments simultaneously. Adjoint-generated sensitivity maps, which can be generated using the adjoint, will be used to demonstrate the optimal locations for deployment of instruments under varying wave conditions.

    Numerous oceanographic processes involved in the transport and survival of larval stages of marine organisms, as well as, in nutrient and phytoplankton delivery, occur in nearshore waters. Yet, while large-scale oceanographic patterns are relatively well known for central Chile, little information exists on temporal and spatial variation in the nearshore environment.

    The mean king problem is a quantum mechanical retrodiction problem, in which Alice has to name the outcome of an ideal measurement made in one of several different orthonormal bases. Alice is allowed to prepare the state of the system and to do a final measurement, possibly including an entangled copy. However, Alice gains knowledge about which basis was measured only after she no longer has access to the quantum system or its copy. We give a necessary and sufficient condition on the bases, for Alice to have a strategy to solve this problem, without assuming that the bases are mutually unbiased. The condition requires the existence of an overall joint probability distribution for random variables, whose marginal pair distributions are fixed as the transition probability matrices of the given bases. In particular, in the qubit case the problem is decided by Bell's original three variable inequality. In the standard setting of mutually unbiased bases, when they do exist, Alice can always succeed. However, for randomly chosen bases her success probability rapidly goes to zero with increasing dimension.

    Part of the continuing series of online exhibitions from the Smithsonian's Freer & Sackler Galleries, Caliphs & Kings provides a sample of the rich history of Islamic Spain, called al-Adalus, from the 8th to the 15th centuries. Online visitors can closely examine ten artworks selected from about ninety on display at the museum through October 2004. A featured work is a 10th century ivory pyxis, or cylindrical container, probably made as a special gift for the favorite concubine of the Umayyad caliph, that includes a poetic inscription in which the container speaks in the first person and describes its function as "a vessel for musk and camphor and ambergris." There are also examples of lusterware; textiles, both carpets and bed coverings; a walnut and ivory chest from Barcelona; an illuminated Hebrew bible from the second half of the 15th century; a gold coin for 50 excelentes issued in about 1497, and a map of the world drawn by Florentine cartographer Juan Vespucci, nephew of Amerigo Vespucci, in 1526 that shows Spain as a superpower at the center of all things.

    The field experiment SWASHX conducted at the Scripps Beach in 2000 has shown that there exist strong alongshore currents in the swash zone and further field measurements were carried out in the Nearshore Canyon Experiment (NCEX) in 2003. These datasets are useful for model development and verification. Although considerable effort has been devoted to the study of swash motions in the literature, phase resolving numerical models for the swash zone still needs further improvements. In particular, an accurate swash motion model is needed whenever we want to simulate, using a time dependent numerical model, both gravity waves and currents on the beach. Recent advances in Boussinesq modeling of surf zone hydrodynamics have offered a promising approach to the study of nearshore currents and swash motions observed during the NCEX. We investigate the swash motion in the presence of alongshore currents in the framework of Boussinesq type models. Two different approaches that resolve the shoreline movement have been implemented into the Boussinesq-type wave model. We test their performances in the presence of waves and currents under field conditions using the NCEX data and under idealized conditions using analytical solutions. Emphasis is given to the magnitude and structure of alongshore currents in the swash zone generated by obliquely incident waves. The study has been supported by the Office of Naval Research.

    The set of hypotheses calling for bar formation at the break point was tested with field data. During two different experiments, waves were measured across the surf zone coincident with the development of a nearshore bar. We use a criterion, based on the wave height to depth ratio, to determine the offshore limit of the inner surf zone. During the first experiment, the bar became better developed and migrated offshore while remaining well within the inner surf zone. During the second experiment, the surf zone was narrower and we cannot rule out the possibility of break point processes contributing to bar development. We conclude that bars are not necessarily coupled with the break point and can become better developed and migrate offshore while being in the inner surf zone landward from initial wave breaking in the outer surf zone. ?? 1989.

    In this paper, a systematic, overall view of theories for periodic waves of permanent form, such as Stokes and cnoidal waves, is described first with their validity ranges. To deal with random waves, a method for estimating directional spectra is given. Then, various wave equations are introduced according to the assumptions included in their derivations. The mild-slope equation is derived for combined refraction and diffraction of linear periodic waves. Various parabolic approximations and time-dependent forms are proposed to include randomness and nonlinearity of waves as well as to simplify numerical calculation. Boussinesq equations are the equations developed for calculating nonlinear wave transformations in shallow water. Nonlinear mild-slope equations are derived as a set of wave equations to predict transformation of nonlinear random waves in the nearshore region. Finally, wave equations are classified systematically for a clear theoretical understanding and appropriate selection for specific applications. PMID:23318680

    2014-06-01

    To provide coastal engineers and scientists with a quantitative evaluation of nearshore numerical wave models in reef environments, we review and compare three commonly used models with detailed laboratory observations. These models are the following: (1) SWASH (Simulating WAves till SHore) (Zijlema et al. 2011), a phase-resolving nonlinear shallow-water wave model with added nonhydrostatic terms; (2) SWAN (Simulating WAve Nearshore) (Booij et al. 1999), a phase-averaged spectral wave model; and (3) XBeach (Roelvink et al. 2009), a coupled phase-averaged spectral wave model (applied to modeling sea-swell waves) and a nonlinear shallow-water model (applied to modeling infragravity waves). A quantitative assessment was made of each model's ability to predict sea-swell (SS) wave height, infragravity (IG) wave height, wave spectra, and wave setup () at five locations across the laboratory fringing reef profile of Demirbilek et al. (2007). Simulations were performed with the "recommended" empirical coefficients as documented for each model, and then the key wave-breaking parameter for each model ( ? in SWASH and ? in both SWAN and XBeach) was optimized to most accurately reproduce the observations. SWASH, SWAN, and XBeach were found to be capable of predicting SS wave height variations across the steep fringing reef profile with reasonable accuracy using the default coefficients. Nevertheless, tuning of the key wave-breaking parameter improved the accuracy of each model's predictions. SWASH and XBeach were also able to predict IG wave height and spectral transformation. Although SWAN was capable of modeling the SS wave height, in its current form, it was not capable of modeling the spectral transformation into lower frequencies, as evident in the underprediction of the low-frequency waves.

  15. EDITORIAL: King of the elements? King of the elements?

    NASA Astrophysics Data System (ADS)

    2010-07-01

    Throughout the history of science, carbon-based research has played a defining role in the development of a range of fundamental and technological fields. It was used in Avagadro's definition of the mole in the early 18th century, it provides the 'backbone' of molecules in organic compounds, and in the environmental debate currently raging in the press and international government discussions, the 'carbon footprint' has become the metric of our species' impact on our planet. Also in nanotechnology, with the discovery of various wonder materials, carbon is once again asserting its claim as king of the elements. Until the 1980s the only known forms of carbon were diamond, graphite and amorphous carbon, as in soot or charcoal. In 1985 Robert Curl, Harold Kroto and Richard Smalley reported the existence of fullerenes, spherical structures comprising hexagonal carbon rings [1], work for which they won the Nobel Prize for Chemistry in 1996 [2]. The discovery of fullerenes was followed in 1991 by Sumio Ijima with the discovery of rolled graphite sheets, the carbon nanotube [3]. The discovery of these novel carbon nanostructures inspired researchers in a range of fields, largely as a result of the extraordinary capacity for investigations of these structures to reveal ever more intriguing properties. One of the fascinating properties attributed to carbon nanotubes is their phenomenal strength, with a Young's modulus of single walled carbon nanotubes approaching a terapascal [4]. Ingenious methods of harnessing this strength have since been developed, including bucky paper, a term used to refer to a mat of randomly self-entangled carbon nanotubes. Steven Crannford and Markus Buehler have recently reported a novel computational technique for probing the mechanical properties of these structures and show that the Young's modulus of bucky paper can be tuned by manipulation of the carbon nanotube type and density [5]. The electrical properties of carbon nanotubes, which depend on the chirality or wrapping angle of the graphite sheet with respect to the tube axis [6], have captured the imagination of researchers working in nanoelectronics. Carbon nanotubes also revealed interesting thermal properties that could lend them to the next generation of nanoscale devices. In 2000, researchers at the California Institute of Technology published the results of molecular dynamics simulations of thermal conductivity in carbon nanotubes [7]. The thermal properties predicted from this work added further promise to the potential of carbon nanotubes in micro- and nanoelectromechanical devices. More recently, researchers from the University of Columbia have studied how to exploit the thermal properties of carbon nanotubes in nanofluids. They report enhancement of heat transfer properties of carbon-nanotube-based nanofluids using a plasma treatment to aid stable dispersion of the nanotubes in water [8]. Eric Pop in Illinois has reported on the role of electrical and thermal contact resistance in Joule breakdown of single-walled carbon nanotubes, including analysis of several published data sets [9]. The work finds universal scaling rules, whereby the breakdown scales linearly with length for carbon nanotubes above a certain length, below which the breakdown is entirely limited by contact resistance. In 2004 another form of carbon came to the fore when researchers at the University of Manchester and the Institute of Microelectronics Technology isolated a single plane of graphite, that is, graphene, using a kind of scotch tape [10]. As with other forms of carbon, investigation of graphene has also revealed fascinating properties that lend the material to a number of applications, such as sensing. The electronic properties of graphene are highly sensitive to the adsorption of molecules such as CO, NO, NO2 and NH3, and a collaboration of researchers from Lanzhou University in China and the University of Sheffield in the UK have further reported on how this sensitivity can be enhanced by two orders of magnitude when the graphene is doped with an impurity s

    2004-12-01

    This research uses the tools of modern medical science to examine the ancient descriptions of the symptoms suffered by King Jehoram who was affected by some disease. The Biblical texts were examined, and passages relating to the disease that afflicted King Jehoram, who ruled in Jerusalem 843-851 B.C., were closely studied. We have not included any commentaries, but referred only to the words of the Bible exactly as written. The Passages ''...the Lord smote him in his bowels with an incurable disease in the process of time, after the end of two years, his bowels fell out by reason of his sickness: so he died of sore diseases'' indicate that the King suffered from some kind of disease which affected his bowels. Among the various diseases which may be associated with prolapse of the bowel, colorectal carcinoma is the most acceptable. It seems that the colorectal carcinoma was poorly differentiated, invaded perirectal adipose tissue, blood vessels, and/or lymphatic vessels, and/or perineural areas, was lymph node positive and reached the 4th stage with the spread of metastases to the distal organs. Viewed by a modern physician, the story of King Jehoram unfolds as possibly the earliest description of a patient afflicted by colorectal carcinoma. PMID:15785440

    Temporal and spatial variability of physical, biological, and optical properties on scales of minutes to months and meters to ˜50 km are examined using an extensive data set collected on the New York Bight continental shelf during the Hyperspectral Coastal Ocean Dynamics Experiment. Measurements from a midshelf mooring and bottom tripod (˜25 km offshore, 24 m water depth) and two nearshore profiling nodes (˜5 km offshore, 15 m water depth) are utilized to quantify and correlate midshelf and nearshore variability. Towed shipboard undulating profilers and a high-frequency radar (CODAR) array provide complementary spatial data. We show that phytoplankton and dissolved matter each accounted for roughly 50% of total absorption (440 nm) at midshelf. In contrast, particulate compared to gelbstoff absorption dominated total absorption at the nearshore location. A relatively high-salinity, low-temperature, low particulate coastal jet decreased turbidity nearshore and advected lower-salinity, higher-chlorophyll waters to the midshelf region, resulting in increased biomass at midshelf. Small-scale (order of a few kilometers) convergence and divergence zones formed from the interaction of semidiurnal tides with mean currents and a water mass/turbidity front. The front resulted in increased decorrelation scales from nearshore (˜1 day) toward midshelf (2-3 days) for optical and biological parameters. We conclude that optical and biological variability and distributions at midshelf and nearshore locations were influenced mainly by semidiurnal tides and the coastal jet. We present insights into nearshore coastal processes and their effects on biology and optics as well as for the design of future nearshore interdisciplinary coastal programs.

    2014-09-01

    The influence of oceanographic features on ichthyoplankton assemblages in the warm temperate nearshore region of Algoa Bay, South Africa, was assessed. The nearshore ichthyoplankton comprised 88 taxa from 34 families. Samples were collected at six stations between August 2010 and July 2012 using a plankton ring net of 750 mm diameter and 500 µm mesh aperture. The majority of larvae collected were in a preflexion stage, indicating the potential importance of the nearshore for newly hatched larvae. Engraulidae dominated the catch (38·4%), followed by Cynoglossidae (28·1%) and Sparidae (8·4%). Larval fish abundance was highest during austral spring and summer (September to February). Unique patterns in responses of each dominant fish species to oceanographic features in the nearshore indicate the sensitivity of the early developmental stage to environmental variables. Using generalized linear models, ichthyoplankton abundance responded positively to upwelling and when warm water plumes originating from an Agulhas Current meander entered Algoa Bay. Highest abundances of Engraulis encrasicolus and Sardinops sagax were observed during Agulhas Plume intrusions into Algoa Bay. When a mixed and stratified water column persisted in the nearshore region of Algoa Bay, larval fish abundance decreased. The nearshore region of Algoa Bay appears to serve as a favourable environment for the accumulation of ichthyoplankton. PMID:25082168

    2012-08-01

    Phytoplankton community compositions within near-shore coastal and estuarine waters of Louisiana were characterized by group diversity, evenness, relative abundance and biovolume. Sixty-six taxa were identified in addition to eight potentially harmful algal genera including Gymnodinium sp. Phytoplankton group diversity was lowest at Vermillion Bay in February 2008, but otherwise ranged between 2.16 and 3.40. Phytoplankton evenness was also lowest at Vermillion Bay in February 2008, but otherwise ranged between 0.54 and 0.77. Dissolved oxygen increased with increased biovolume (R² = 0.85, p < 0.001) and biovolume decreased with increased light attenuation (R² = 0.34, p = 0.007), which supported the importance of light in regulating oxygen dynamics. Diatoms were dominant in relative abundance and biovolume at almost all stations and all cruises. Brunt-Väisälä frequency was used as a measure of water column stratification and was negatively correlated (p = 0.02) to diatom relative percent total abundance. PMID:22498318

    Aquatic food webs that incorporate multiple energy channels (e.g., nearshore benthic and pelagic) with varying productivity and turnover rates convey stability to biological communities by providing independent energy sources. Within the Lake Michigan food web, invasive dreissenid mussels have caused rapid changes to food web structure and potentially altered the channels through which consumers acquire energy. We used stable C and N isotopes to determine how Lake Michigan food web structure has changed in the past decade, coincident with the expansion of dreissenid mussels, decreased pelagic phytoplankton production, and increased nearshore benthic algal production. Fish and invertebrate samples collected from sites around Lake Michigan were analyzed to determine taxa-specific 13C:12C (delta13C) and 15N:14N (delta15N) ratios. Sampling took place during two distinct periods, 2002-2003 and 2010-2012, that spanned the period of dreissenid expansion, and included nearshore, pelagic and profundal fish and invertebrate taxa. The magnitude and direction of the delta13C shift indicated significantly greater reliance upon nearshore benthic energy sources among nearly all fish taxa as well as profundal invertebrates following dreissenid expansion. Although the mechanisms underlying this delta13C shift likely varied among species, possible causes include the transport of benthic algal production to offshore waters and increased feeding on nearshore prey items by pelagic and profundal species. delta15N shifts were more variable and of smaller magnitude across taxa, although declines in delta15N among some pelagic fishes suggest a shift to alternative prey resources. Lake Michigan fishes and invertebrates appear to have responded to dreissenid-induced changes in nutrient and energy pathways by switching from pelagic to alternative nearshore energy subsidies. Although large shifts in energy allocation (i.e., pelagic to nearshore benthic) resulting from invasive species appear to affect total production at upper trophic levels, changes in trophic structure and utilization of novel energy pathways may help to stabilize food webs following species invasions.

    The King's Cross fire occurred at the end of the evening rush hour, on 18 November 1987. King's Cross station is within the department's health district and we felt a responsibility to respond to the psychological aftermath. The unique features of our intervention were the degree of inter agency coordination, the use of a systematic outreach and screening programme, the collection of psychotherapy outcome measures and the development of an ongoing clinic. The work represents a sustained attempt to assess the nature and prevalence of post-traumatic reactions and the most medically and economically effective form of intervention. In this paper we describe the way our team responded to the high level of psychological distress that we found, we present some preliminary results, outline two therapeutic trials, and refer to the longterm consequences for the work of our department.

  5. Drag kings in the new wave: gender performance and participation.

    PubMed

    Surkan, Kim

    2002-01-01

    In an examination of Midwestern drag king performers and communities that have emerged since the study by Volcano and Halberstam of king cultures in London, New York, and San Francisco, this article considers traditional and alternative ways of "doing drag," both performative and participatory, as a means of interrogating the proximity of a "new wave" of king culture to academic theory. Tracing the evolution of drag king performance in the Twin Cities from the 1996 workshop by Diane Torr to the formation of two distinct king troupes in the late 1990s demonstrates a particular trajectory in kinging that reflects a new consciousness and enactment of gender theory through artistic praxis. Participation plays a key role in breaking down the distance between spectator and performer in venues such as the First International Drag King Extravaganza in Columbus, Ohio, and Melinda Hubman's art installation "Performing Masculinities: Take a Chance on Gender" in Minneapolis. By engaging the "audience" in drag, the Extravaganza "Science Fair" successfully referenced drag kings' shared history with early American freak shows in a clever and critical way. Moving beyond the contest framework of early king shows, new drag king troupes like Minneapolis' Dykes Do Drag are "mixing it up" in an attempt to complicate notions of butch/femme gender roles, sexuality, and drag stereotypes.

    The extent to which the occurrence of falls, the dominant feature of human attempts to balance a stick at their fingertip, can be predicted is examined in the context of the "Dragon-King" hypothesis. For skilled stick balancers, fluctuations in the controlled variable, namely the vertical displacement angle ?, exhibit power law behaviors. When stick balancing is made less stable by either decreasing the length of the stick or by requiring the subject to balance the stick on the surface of a table tennis racket, systematic departures from the power law behaviors are observed in the range of large ?. This observation raises the possibility that the presence of departures from the power law in the large length scale region, possibly Dragon-Kings, may identify situations in which the occurrence of a fall is more imminent. However, whether or not Dragon-Kings are observed, there is a Weibull-type survival function for stick falling. The possibility that increased risk of falling can, at least to some extent, be predicted from fluctuations in the controlled variable before the event occurs has important implications for the development of preventative strategies for the management of phenomena ranging from earthquakes to epileptic seizures to falls in the elderly.

  8. cBathy: A robust algorithm for estimating nearshore bathymetry

    Holman, Rob; Plant, Nathaniel; Holland, Todd

    2013-05-01

    A three-part algorithm is described and tested to provide robust bathymetry maps based solely on long time series observations of surface wave motions. The first phase consists of frequency-dependent characterization of the wave field in which dominant frequencies are estimated by Fourier transform while corresponding wave numbers are derived from spatial gradients in cross-spectral phase over analysis tiles that can be small, allowing high-spatial resolution. Coherent spatial structures at each frequency are extracted by frequency-dependent empirical orthogonal function (EOF). In phase two, depths are found that best fit weighted sets of frequency-wave number pairs. These are subsequently smoothed in time in phase 3 using a Kalman filter that fills gaps in coverage and objectively averages new estimates of variable quality with prior estimates. Objective confidence intervals are returned. Tests at Duck, NC, using 16 surveys collected over 2 years showed a bias and root-mean-square (RMS) error of 0.19 and 0.51 m, respectively but were largest near the offshore limits of analysis (roughly 500 m from the camera) and near the steep shoreline where analysis tiles mix information from waves, swash and static dry sand. Performance was excellent for small waves but degraded somewhat with increasing wave height. Sand bars and their small-scale alongshore variability were well resolved. A single ground truth survey from a dissipative, low-sloping beach (Agate Beach, OR) showed similar errors over a region that extended several kilometers from the camera and reached depths of 14 m. Vector wave number estimates can also be incorporated into data assimilation models of nearshore dynamics.

    2005-01-01

    [1] Evolution of a tectonically active coast is driven by geomorphically destructive energy supplied by ocean waves. Wave energy is episodic and concentrated; sea cliffs are battered by the geomorphic wrecking ball every 4-25 s. We measure the response of sea cliffs to wave assault by sensing the ground motion using near-coastal seismometers. Sea cliffs respond to waves in two distinct styles. High-frequency motion (20 Hz) reflects the natural frequency of the sea cliff as it rings in response to direct wave impact. Low-frequency motion in the 0.1-0.05 Hz (10-20 s) band consistently agrees with the dominant nearshore wave period. Integrating microseismic velocities suggests 50 ??m and 10 ??m displacements in horizontal and vertical directions, respectively. Displacement ellipsoids exhibit simultaneous downward and seaward sea cliff motion with each wave. Video footage corroborates the downward sea cliff flex in response to the imposed water load on the wave cut platform. Gradients in displacement amplitudes documented using multiple seismometers suggest longitudinal and shear strain of the flexing sea cliff on the order of 0.5-4 ?? strains during each wave loading cycle. As this sea cliff flexure occurs approximately 3 million times annually, it has the potential to fatigue the rock through cyclical loading. Local sea cliff retreat rates of 10 cm/yr imply that a given parcel of rock is flexed through roughly 109 cycles of increasing amplitude before exposure to direct wave attack at the cliff face.

  10. A High Resolution Hydrodynamic Model of Puget Sound to Support Nearshore Restoration Feasibility Analysis and Design

    Khangaonkar, Tarang; Yang, Zhaoqing

    2011-01-01

    Estuarine and coastal hydrodynamic processes are sometimes neglected in the design and planning of nearshore restoration actions. Despite best intentions, efforts to restore nearshore habitats can result in poor outcomes if circulation and transport which also affect freshwater-saltwater interactions are not properly addressed. Limitations due to current land use can lead to selection of sub-optimal restoration alternatives that may result in undesirable consequences, such as flooding, deterioration of water quality, and erosion, requiring immediate remedies and costly repairs. Uncertainty with achieving restoration goals, such as recovery of tidal exchange, supply of sediment and nutrients, and establishment of fish migration pathways, may be minimized by using numerical models designed for application to the nearshore environment. A high resolution circulation and transport model of the Puget Sound, in the state of Washington, was developed to assist with nearshore habitat restoration design and analysis, and to answer the question “can we achieve beneficial restoration outcomes at small local scale, as well as at a large estuary-wide scale?” The Puget Sound model is based on an unstructured grid framework to define the complex Puget Sound shoreline using a finite volume coastal ocean model (FVCOM). The capability of the model for simulating the important nearshore processes, such as circulation in complex multiple tidal channels, wetting and drying of tide flats, and water quality and sediment transport as part of restoration feasibility, are illustrated through examples of restoration projects in Puget Sound.

  11. A New Reading of Shakespeare's King John.

    NASA Astrophysics Data System (ADS)

    Usher, Peter D.

    1995-12-01

    Shakespeare wrote King John c.1594, six years after the defeat of the Spanish Armada, and ~ 50 years after publication of the Copernican heliocentric hypothesis. It is said to be the most unhistorical of the History Plays, ``anomalous'', ``puzzling'', and ``odd'', and as such it has engendered far more than the customary range of interpretive opinion. I suggest that the play alerts Elizabethans not just to military and political threats, but to a changing cosmic world view, all especially threatening as they arise in Catholic countries. (a) Personification characterizes the play. John personifies the old order, while Arthur and the Dauphin's armies personify the new. I suggest that Shakespeare decenters King John just as Copernicus decentered the world. (b) Hubert menaces Arthur's eyes for a whole scene (4.1), but the need for such cruelty is not explained and is especially odd as Arthur is already under sentence of death (3.3.65-66). This hitherto unexplained anomaly suggests that the old order fears what the new might see. (c) Eleanor's confession is made only to Heaven and to her son the King (1.1.42-43), yet by echoing and word play the Messenger from France later reveals to John that he is privy to it (4.2.119-124). This circumstance has not been questioned heretofore. I suggest that the Messenger is like the wily Hermes (Mercury), chief communicator of the gods and patron of the sciences; by revealing that he moves in the highest circles, he tells John that he speaks with an authority that transcends even that of a king. The message from on high presages more than political change; it warns of a new cosmic and religious world order (d) Most agree that John is a weak king, so Shakespeare must have suspected flaws in the old ways. He would have known that Tycho Brahe's new star of 1572, the comet of 1577, and the 1576 model of his compatriot Thomas Digges, were shattering old ideas. (e) The tensions of the play are not resolved because in 1594 the new order was not yet generally accepted. Instead, the new world view is announced subtly, and thereby perhaps prudently, for the onset of persecution of its advocates is only a few years away.

  15. Breakpoint-forced and bound long waves in the nearshore: A model comparison

    USGS Publications Warehouse

    List, Jeffrey H.

    1993-01-01

    A finite-difference model is used to compare long wave amplitudes arising from two-group forced generation mechanisms in the nearshore: long waves generated at a time-varying breakpoint and the shallow-water extension of the bound long wave. Plane beach results demonstrate that the strong frequency selection in the outgoing wave predicted by the breakpoint-forcing mechanism may not be observable in field data due to this wave's relatively small size and its predicted phase relation with the bound wave. Over a bar/trough nearshore, it is shown that a strong frequency selection in shoreline amplitudes is not a unique result of the time-varying breakpoint model, but a general result of the interaction between topography and any broad-banded forcing of nearshore long waves.

    2010-11-01

    We optimize groundwater management in the presence of marine consequences of submarine groundwater discharge (SGD). Concern for marine biota increases the optimal steady-state head level of the aquifer. The model is discussed in general terms for any coastal groundwater resource where SGD has a positive impact on valuable nearshore resources. Our application focuses on the Kona Coast of Hawai`i, where SGD is being actively studied and where both nearshore ecology and groundwater resources are serious sociopolitical issues. To incorporate the consequences of water extraction on nearshore resources, we impose a safe minimum standard for the quantity of SGD. Efficient pumping rates fluctuate according to various growth requirements on the keystone marine algae and different assumptions regarding recharge rates. Desalination is required under average recharge conditions and a strict minimum standard and under low recharge conditions regardless of minimum standards of growth.

  3. Dispersal of fine sediment in nearshore coastal waters

    USGS Publications Warehouse

    Warrick, Jonathan A.

    2013-01-01

    Fine sediment (silt and clay) plays an important role in the physical, ecological, and environmental conditions of coastal systems, yet little is known about the dispersal and fate of fine sediment across coastal margin settings outside of river mouths. Here I provide simple physical scaling and detailed monitoring of a beach nourishment project near Imperial Beach, California, with a high portion of fines (40% silt and clay by weight). These results provide insights into the pathways and residence times of fine sediment transport across a wave-dominated coastal margin. Monitoring of the project used physical, optical, acoustic, and remote sensing techniques to track the fine portion of the nourishment sediment. The initial transport of fine sediment from the beach was influenced strongly by longshore currents of the surf zone that were established in response to the approach angles of the waves. The mean residence time of fine sediment in the surf zone—once it was suspended—was approximately 1 hour, and rapid decreases in surf zone fine sediment concentrations along the beach resulted from mixing and offshore transport in turbid rip heads. For example, during a day with oblique wave directions and surf zone longshore currents of approximately 25 cm/s, the offshore losses of fine sediment in rips resulted in a 95% reduction in alongshore surf zone fine sediment flux within 1 km of the nourishment site. However, because of the direct placement of nourishment sediment on the beach, fine suspended-sediment concentrations in the swash zone remained elevated for several days after nourishment, while fine sediment was winnowed from the beach. Once offshore of the surf zone, fine sediment settled downward in the water column and was observed to transport along and across the inner shelf. Vertically sheared currents influenced the directions and rates of fine sediment transport on the shelf. Sedimentation of fine sediment was greatest on the seafloor directly offshore of the nourishment site. However, a mass balance of sediment suggests that the majority of the fine sediment moved far away (over 2 km) from the nourishment site or to water depths greater than 10 m, where fine sediment represents a substantial portion of the bed material. Thus, the fate of fine sediment in nearshore waters was influenced strongly by wave conditions, surf zone and rip current transport, and the vertical density and flow conditions of coastal waters.

  4. Hydrothermal influence on nearshore sediments of Kos Island, Aegean Sea

    NASA Astrophysics Data System (ADS)

    Megalovasilis, Pavlos; Godelitsas, Athanasios

    2015-04-01

    The Kos-Nisyros volcanic centre is a long-active, Plio-Pleistocene magmatic system in the subduction zone along the easternmost edge of the active Hellenic volcanic arc in the Aegean Sea. Although today there are signs of relative quiescence in volcanic activity, active onshore fumaroles and shallow-sea hydrothermal vents persist on, amongst others, the island of Kos. The present study explores the large-scale imprint of hydrothermally sourced heavy metals and nutrients on the island's coastal marine environment, based on geochemical data collected in September 2007 from hydrothermal waters and surficial nearshore sediments (<10 m water depth) at several vents in the Bros Thermi and Kephalos Bay hydrothermal fields. There were strong spatiotemporal fluctuations in gas and water flow rates at the vent sites—for example, the gas/water flux ratio varied by as much as two orders of magnitude (0.03-1.30) at Kephalos Bay vents over a 2-day measurement period on 15-16 September 2007. Confirming earlier work, hydrothermal waters had higher levels of F, Ca and Sr, and lower levels of Na, Mg and SO4 compared with ambient seawater. Moreover, there was novel evidence of strong, widespread Zn and also Mn enhancement. Cluster and factor analyses of surficial sediment data from the Bros Thermi vents (fine (mud) fractions, <63 ?m, 6N HCl dissolution) revealed distinct groups of elements such as Cu+Pb+Zn and Mn+Mg. Spatial distribution maps showed similarities in the dispersion of Cu and Pb, and of Ca and Ba. The distribution of HCl-soluble material is the inverse mirror image of the distribution of the residual (silicate and Al-silicate) phase. These findings considerably expand on existing knowledge that the coastal zone of Kos is severely influenced by ongoing submarine hydrothermal activity, and confirm that shallow-water sediment Fe, Mn, Zn and Pb levels are substantially higher than those of other islands along the Hellenic volcanic arc, and even exceed those of some deep-water hydrothermal vents in other world regions. Evidently, there may be significant metallic sulphide deposits of hydrothermal origin at depth beneath Kos.

At the nanoscale, things are so small that surface area effects impact the behavior of materials. For example, things tend to stick together and gravity plays a minor role. This activity gives students the opportunity to explore the sizes of things and scale as they investigate questions like "Could an egg ever grow to be the size of a beach ball?"

    Improvements and advances in technology permit the measurement of sediment transport and fluid dynamics at increasingly smaller temporal and spatial scales. While these studies provide greater insight about small-scale processes, it remains unclear how to transfer this improved understanding of these processes to the convergences and divergences of transport that are ultimately responsible for the evolution of nearshore, beach and dune environments. A series of field experiments are used to examine how small-scale processes and the exchange of sediment amongst the nearshore, beach and dune is dependent on the antecedent morphology. Specifically, the transport of sediment from beach to dune is shown to depend on the synchronization of sediment supply and transport potential that vary as the beach and backshore evolve. The evolution of the beach and backshore in turn depends on the transformation of the incident wave field over the nearshore profile, which is dependent on the bathymetry of the inner-shelf. In this respect, the interaction of nearshore, beach and dune systems is self-reinforcing and evidence is presented to show this interaction is responsible for the alongshore variation in barrier island morphology. It is argued that the dependency of process on morphology creates new opportunities for research in which changes in process vary with changes morphology in both space and time.

    The western arctic population of King Eiders (Somateria spectabilis) has declined by >50% in recent years. A health assessment was conducted for adult King Eiders breeding on the north slope of Alaska, USA, to evaluate body condition (n=90, 2002-2006) and baseline biochemical and hematologic values (n=20-30, 2005-2006). Body condition for males and females was excellent. Total protein, calcium, alkaline phosphatase, amylase, and globulin were significantly higher in females than in males, likely because of differences in reproductive physiology. These baseline health data can be used to promote conservation of King Eiders and other closely related species of concern. PMID:20966282

  10. Correlation of Sub-Aerial Beach Change with Numerical Model Derived Nearshore Wave Conditions

    NASA Astrophysics Data System (ADS)

    2007-12-01

    Wave-induced sediment transport on and off of beaches is difficult to understand and predict without thorough knowledge of the nearshore wave conditions. Wave data is commonly provided by a buoy located offshore in deep water that measures waves prior to shoaling and refraction. Irregular bathymetry causes dissimilar refraction and shoaling and can lead to variable wave conditions in the nearshore environment. To account for wave propagation over varying bathymetry, numerical wave models are good tools for estimating the nearshore wave climate from offshore wave data. Ocean Beach in San Francisco, CA is an energetic, intermediately sloping beach that was the subject of frequent sub-aerial topographic surveys in 2005 and 2006, with some surveys being as close as two days apart. Sediment volume change derived from these surveys was correlated to nearshore wave heights estimated from offshore buoy measurements and the application of the numerical wave model SWAN (Simulating WAves Nearshore). The SWAN model was used to create a "look-up" table of nearshore wave heights from over 4500 combinations of offshore wave heights, periods, and directions. The model was run using a nested grid scheme using three separate spatial resolutions, with the finest being closest to shore. Correlations between the sub-aerial beach volume data at five morphologically different reaches of Ocean Beach and the SWAN derived wave heights from just outside of the surf zone (in 5, 7.5, or 10 m of water depending on wave height) are generally low, with R2 values less than 0.5, with the highest being 0.61. Although the coefficients of determination are low in most instances the significance exceeds 90%. The reason for the low coefficients of determination is not known but is currently being investigated; some possible reasons are improper characterization of the lengthy time series of wave data between surveys (up to 28 days), or the ignored effect of strong along-shore directed tidal currents (O(~1m/s)) on breaking waves in the surf zone.

    2012-10-01

    The dispersants Corexit 9527 and Corexit 9500 were extensively used during the response to the Deepwater Horizon accident in 2010. In addition to the monitoring programs established by federal and state governments, local communities also conducted studies to determine if chemical constituents from these dispersants impacted nearshore and inland waters. One community (the City of Orange Beach, Alabama) collected water samples between September, 2010 and January, 2011, and found the dispersant-related chemicals propylene glycol, 2-butoxyethanol, and dioctyl sodium sulfosuccinate at nearshore and inland water sampling sites. In this paper, we examine their dataset in an attempt to discern the origin of these chemicals. Our assessment indicates that these compounds are unlikely to be present as a result of the use of Corexit dispersants; rather, they are likely related to point and non-point source stormwater discharge.

    2013-12-01

    We studied the distribution of As, Fe, Ca and Al in beach sands and near-shore surface sediments along the Brazilian coast from the equatorial zone to Rio de Janeiro state. High concentrations of As (up to 120 mg kg-1) exceeding the environmentally acceptable thresholds were found in the beach sands and near-shore surface sediment in several segments of the studied coast. That increased from north to south. The significant positive correlation (R2 = 0.58) between As and calcium carbonate in the beach sands corroborated the hypothesis that calcareous bioclasts participate in metalloid retention and its accumulation in beach sediments. Most likely, enrichment of As occurs in the oxic horizon of sediments caused by the diagenetic redistribution of various elements. Enrichment of As in beach sands occurs in the coast of Bahia and Espirito Santo states. That is facilitated by clastic material of calcareous algae.

    NASA Astrophysics Data System (ADS)

    Matzelle, A.; Helmuth, B.; Lakshmi, V.

    2011-12-01

    The physiological performance of intertidal and shallow subtidal invertebrates and algae is significantly affected by water temperature, and so the ability to measure and model onshore water temperatures is critical for ecological and biogeographic studies. Because of the localized influences of processes such as upwelling, mixing, and surface heating from solar radiation, nearshore water temperatures can differ from those measured directly offshore by buoys and satellites. It remains an open question what the magnitude of the differences in these temperatures are, and whether "large pixel" measurements can serve as an effective proxy for onshore processes, particularly when extrapolating from laboratory physiological studies to field conditions. We compared 9 years of nearshore (~10km) MODIS (Terra and Aqua overpasses) SST data against in situ measurements of water temperature conducted at two intertidal sites in central Oregon- Boiler Bay and Strawberry Hill. We collapsed data into increasingly longer temporal averages to address the correlation and absolute differences between onshore and nearshore temperatures over daily, weekly and monthly timescales. Results indicate that nearshore SST is a reasonable proxy for onshore water temperature, and that the strength of the correlation increases with decreasing temporal resolution. Correlations between differences in maxima are highest, followed by average and minima, and were lower at a site with regular upwelling. While average differences ranged from ~0.199-1.353°C, absolute differences across time scales were ~0.446-6.906°C, and were highest for cold temperatures. The results suggest that, at least at these two sites, SST can be used as a relative proxy for general trends only, especially over longer time scales.

In the case of wave breaking, there is significant mixing of air and water at the wave crest, along with relatively high kinetic energy, so prediction of the free surface is complicated. Most hydrodynamic numerical studies are derived from single-phase flow, in which the role of air is neglected. Therefore, single-phase flow modelling may not be a suitable tool for simulating nearshore hydrodynamics and, consequently, sediment transport. Two-phase flow modelling produces more realistic free-surface shapes. The two-dimensional two-phase Navier-Stokes equations, volume of fluid technique and a two-equation turbulence closure model were used to predict wave breaking and runup, and compared with experimental data. Comparison of the results with a corresponding single-phase flow model revealed that the inclusion of both air and water phases leads to an improvement in simulation of hydrodynamic characteristics especially in the vicinity of the breaking point. The results reveal that the two-phase model provides higher accuracy and reliability for the free surface prediction and flow field estimation than a 2D single-phase model.

    River discharge supplies nearshore communities with a terrestrial carbon source that is often reflected in invertebrate and fish consumers. Recent studies in the Beaufort Sea have documented widespread terrestrial carbon use among invertebrates, but only limited use among nearshore fish consumers. Here, we examine the carbon source and diet of rapidly growing young-of-year Arctic cisco (Coregonus autumnalis) using stable isotope values (?13C and ?15N) from muscle and diet analysis (stomach contents) during a critical and previously unsampled life stage. Stable isotope values (?15N and ?13C) may differentiate between terrestrial and marine sources and integrate over longer time frames (weeks). Diet analysis provides species-specific information, but only from recent foraging (days). Average ?13C for all individuals was ?25.7 ‰, with the smallest individuals possessing significantly depleted ?13C values indicative of a stronger reliance of terrestrial carbon sources as compared to larger individuals. Average ?15N for all individuals was 10.4 ‰, with little variation among individuals. As fish length increased, the proportion of offshore Calanus prey and neritic Mysis prey increased. Rapid young-of-year growth in Arctic cisco appears to use terrestrial carbon sources obtained by consuming a mixture of neritic and offshore zooplankton. Shifts in the magnitude or phenology of river discharge and the delivery of terrestrial carbon may alter the ecology of nearshore fish consumers.

  14. Impact of sea-breeze activity on nearshore and foreshore processes in southwestern Australia

    In coastal regions sheltered from the direct impact of swell- and storm-wave activity, locally generated wind waves, particularly those associated with strong sea-breeze activity, play a dominant role in controlling nearshore and foreshore processes. Field data collected from the Perth Metropolitan Coast (western Australia) during a typical summer sea-breeze cycle, are presented. It is demonstrated that the nearshore environment responds rapidly to an increase in wind speed (up to 12 m s -1) during the sea breeze, resulting in considerable changes to the nearshore hydrodynamics and morphology. Incident wave energy increased during the sea breeze and was associated with development of a wind-wave field with significant wave heights up to 0.9 m. Nearshore currents responded to this change in wave climate with the development of net offshore near-bed currents and a rapid increase in the mean longshore current from < 0.05 m s -1 to 1.0 m s -1 A 10-fold increase in suspended sediment concentration and a 100-fold increase in the longshore sand transport resulted from the effects of the sea-breeze system. Erosion of the beachface was coincident with the development of the wind-wave field. Sea breeze wave-driven water circulation also completely eroded beach cusps (wavelength 20-30 m), overwhelmed the rip current system associated with the beach cusps and suppressed the infra-gravity wave frequencies in the incident wave and swash record. The beach cusps reformed after the cessation of the sea breeze. It is demonstrated that the beachface is in a constant stage of adjustment to the incident wave energy through the diurnal sea-breeze cycle alternating between dissipative and reflective morphodynamic regimes. The results may be used to determine the impact of a medium-sized storm on the beachface. It is clear that the sea-breeze system plays a major role in controlling the nearshore and foreshore processes not only in this region, but also on other geographic locations where strong sea breezes are present.

  15. A user-friendly quantitative approach to classifying nearshore marine habitats along a heterogeneous coast

    A scheme, which can be readily used by fisheries and environmental managers and ecologists, has been developed for quantitatively classifying the different habitats found in nearshore marine waters along the heterogeneous lower west coast of Australia. Initially, 25 beach sites, representing a wide range of nearshore environments, were separated into six a priori habitat types on the basis of characteristics that could readily be observed and were likely to influence the extent to which a particular (fish) species occupies a particular habitat. Focus was thus placed on such features as the degree of exposure to wave activity and whether or not seagrass and/or reefs were present in the nearshore vicinity. Subsequently, quantitative data for 27 environmental variables, considered likely to characterise the six habitat types, were obtained for each of the 25 sites from readily accessible sources. When the latter data were subjected to multidimensional scaling (MDS) ordination, the points for the sites representing only three of those six habitat types formed discrete groups. The BVSTEP routine in the PRIMER v5.0 statistical package (Clarke & Gorley, Primer v5.0: User Manual/Tutorial, Primer-E Ltd, Plymouth, 2001) was thus used to select a subset of the 27 environmental variables that would provide a better resolution of the six a priori habitat types. This process involved matching the distance matrix constructed from the quantitative environmental data with a matrix constructed from scored data that reflected the criteria for the initial a priori classification scheme. A subset of seven environmental variables gave the best correlation between the two matrices ( ?=0.823), and thus provided the optimal set of quantitative data for discriminating between the six a priori habitat types. These variables comprised both the direct and north-westerly fetches, the minimum distance from the shoreline to the 2 m depth contour, the distance from the shoreline to the first offshore reef chain along a south-westerly transect, and the relative contributions of bare sand, subtidal reef and seagrass. Data for these characteristics at any nearshore site along the coastline can readily be recorded by managers and ecologists and subjected to the 'nearest-replicate' classification procedure developed in this study to ascertain the habitat type to which that site should be assigned. Current work is using MDS ordination, in conjunction with associated statistical tests and the BVSTEP routine, to elucidate the extent to which the compositions of assemblages of fish, benthic macroinvertebrates, meiofauna and zooplankton in nearshore waters along the lower west coast of Australia are related to habitat type(s).

    The County of Santa Cruz Department of Public Works and the County of Santa Cruz Redevelopment Agency requested the U.S. Geological Survey (USGS) Western Coastal and Marine Geology Team (WCMG) to provide baseline geologic and oceanographic information on the coast and inner shelf at Pleasure Point, Santa Cruz County, California. The rationale for this proposed work is a need to better understand the environmental consequences of a proposed bluff stabilization project on the beach, the nearshore and the surf at Pleasure Point, Santa Cruz County, California. To meet these information needs, the USGS-WCMG Team collected baseline scientific information on the morphology and waves at Pleasure Point. This study provided high-resolution topography of the coastal bluffs and bathymetry of the inner shelf off East Cliff Drive between 32nd Avenue and 41st Avenue. The spatial and temporal variation in waves and their breaking patterns at the study site were documented. Although this project did not actively investigate the impacts of the proposed bluff stabilization project, these data provide the baseline information required for future studies directed toward predicting the impacts of stabilization on the sea cliffs, beach and nearshore sediment profiles, natural rock reef structures, and offshore habitats and resources. They also provide a basis for calculating potential changes to wave transformations into the shore at Pleasure Point.

Jud came to Berkeley in 1963 as assistant professor of chemical engineering, following receipt of a doctor's degree from MIT and a subsequent short appointment as director of the MIT chemical engineering practice school station at what was then Esso (now Exxon) in New Jersey. His undergraduate degree is from Yale. Starting with his MIT doctoral dissertation on gas absorption, Jud has devoted much of his professional career to separation processes. His teaching and research activities have been primarily concerned with separation of mixtures with emphasis on liquid-liquid extraction and drying. As a consultant to Procter and Gamble, he contributed to the technology of making instant coffee. His life-long activities in hiking and camping stimulated Jud's interest in the manufacture of freeze-dried foods (e.g. turkey meat) to minimize the weight of his hiking back-pack. Jud is internationally known not only for his many research publications but even more, for his acclaimed textbook ''Separation Processses'' (McGraw-Hill, second edition 1980) that is used in standard chemical engineering courses in the US and abroad.

  20. Spatial pattern of current-driven hits to the nearshore from a major marine fairway in the Gulf of Finland

    2014-01-01

    The spatial pattern of hits to the nearshore by tracers originating in a major fairway in the Gulf of Finland and transported by surface currents is analysed based on Lagrangian trajectories of water parcels reconstructed using the TRACMASS model from three-dimensional velocity fields by the Rossby Centre circulation model RCO for 1987-1996. The probabilities for a hit to different parts of the nearshore and the ability of different sections of the fairway to serve as starting points of tracers (equivalently, certain type of nearshore pollution) have extensive seasonal variability. The potential of the fairway to impact the nearshore in this manner is roughly inversely proportional to its distance from the nearest coast. A short section of the fairway to the south of Vyborg and a segment to the west of Tallinn are the most probable starting points of tracers. The most frequently hit nearshore areas are short fragments between Hanko and Helsinki, the north-eastern coast of the gulf to the south of Vyborg, and longer segments from Tallinn to Hiiumaa on the southern coast of the gulf.

  1. Development of multi-year land cover data to assess wildfire impacts to coastal watersheds and the nearshore environment

    NASA Astrophysics Data System (ADS)

    Morrison, Katherine D.

    In the Mediterranean ecosystems of coastal California, wildfire is a common disturbance that can significantly alter vegetation in watersheds that transport sediment and nutrients to the adjacent nearshore oceanic environment. We assess the impact of two wildfires that burned in 2008 on land cover and to the nearshore environment along the Big Sur coast in central California. We created a multi-year land cover dataset to assess changes to coastal watersheds as a result of fire. This land cover dataset was then used to model changes in nonpoint source pollutants transported to the nearshore environment. Results indicate post-fire increases in percent export compared to pre-fire years and also link wildfire severity to the specific land cover changes that subsequently increase exports of pollutants and sediment to the nearshore environment. This approach is a replicable across watersheds and also provides a framework for including the nearshore environment as a value at risk terrestrial land management revolving around wildfire, including suppression, thinning, and other activities that change land cover at a landscape scale.

    Helen Dean King's scientific work focused on inbreeding using experimental data collected from standardized laboratory rats to elucidate problems in human heredity. The meticulous care with which she carried on her inbreeding experiments assured that her results were dependable and her theoretical explanations credible. By using her nearly homozygous rats as desired commodities, she also was granted access to venues and people otherwise unavailable to her as a woman. King's scientific career was made possible through her life experiences. She earned a doctorate from Bryn Mawr College under Thomas Hunt Morgan and spent a productive career at the Wistar Institute of Anatomy and Biology in Philadelphia where she had access to the experimental subjects which made her career possible. In this paper I examine King's work on inbreeding, her participation in the debates over eugenics, her position at the Wistar Institute, her status as a woman working with mostly male scientists, and her involvement with popular science.

    This report provides soil evaluation and characterization testing for the submarine bases at Kings Bay, Georgia, and Bangor, Washington, using triaxial testing at high confining pressures with different moisture contents. In general, the samples from the Bangor and Kings Bay sites appeared to be stronger than a previously used reference soil. Assuming the samples of the material were representative of the material found at the sites, they should be adequate for use in the planned construction. Since soils can vary greatly over even a small site, a soil specification for the construction contractor would be needed to insure that soil variations found at the site would meet or exceed the requirements. A suggested specification for the Bangor and Kings Bay soils was presented based on information gathered from references plus data obtained from this study, which could be used as a basis for design by the construction contractor.

    Hydrologic data collected in the Cedar and Snoqualmie River basins on the west slope of the Cascade Range have been analyzed to determine the amount of water lost by seepage from Chester Morse Lake and Masonry Pool and the. consequent gain by seepage to the Cedar and South Fork Snoqualmie Rivers. For water years 1957-64, average losses were about 220 cfs (cubic feet per second) while average gains were about 180 cfs in the Cedar River and 50 cfs in the South Fork Snoqualmie River. Streamflow and precipitation data for water years 1908-26 and 1930-F2 indicate that a change in runoff regimen occurred in Cedar and South Fork Snoqualmie Rivers after the Boxley Creek washout in December 1918. For water years 1919-26 and 1930-32, the flow of Cedar River near Landsburg averaged about 80 cfs less than it would have if the washout had not occurred. In contrast, the flow of South Fork Snoqualmie River at North Bend averaged about 60 cfs more than it would have.

    A water budget prepared for Wilderness Lake, a candidate for lake-quality restoration, indicates that of the 530 acre-feet of water that enters the lake each year, 170 acre-feet is from precipitation and 360 acre-feet is from groundwater inflow. An equal amount leaves the lake, and of this, 380 acre-feet is by surface runoff, 8 acre-feet is by groundwater seepage, and 140 acre-feet is by evaporation. Based on these amounts of inflow and outflow, the theoretical water-renewal time of the lake is calculated to be 2.6 years. The annual contributions of nitrogen and phosphorus to the lake from precipitation, natural ground water, and septic-tank leachate are about 920 kilograms nitrogen and 38 kilograms phosphorus. Nitrogen and phosphorus contributions from other sources were not assessed but could be significant. (Woodard-USGS)

A nearly equal amount of water leaves the lake and of this, 130 acre-feet is by evaporation, 659 acre-feet is by surface runoff, and less than one acre-foot is by ground-water seepage. Based on these amounts of inflow and outflow, the theoretical water-renewal time of the lake is calculated to be 2.2 years.

    Historical shoreline changes to hydrologic characteristics were studied for Lake Washington and the route of Lake Washington Ship Canal. The study is based on comparison of maps made during the period 1875-1907 and modern topographic maps, supplemented with historical documents that describe the once-natural setting of the lakes and streams in the Lake Washington drainage basin. The observed shoreline changes range from minor to substantial. The water-surface area has been historically reduced by about 6 square kilometers, and total shoreline has been reduced by 20 kilometers. Approximately 4 square kilometers of the historical wetland area has been eliminated, or about 93 percent of the natural wetland extent. The changes have resulted from construction of the Lake Washington Ship Canal and accompanying water-level adjustments, shoreline modification from urban growth of the area, and limited natural processes. The map comparison documents (1) extent of shoreline changes (2) historical loss of wetlands area, (3) loss of small streams that historically entered the lakes and bays, and (4) historical vegetation and land-use patterns around the lakeshore and canal route. The identification of historical shorelines, wetlands, and small streams that have no expression on today 's landscape is information of value to land-use planning and local engineering activities.

    Bedrock of the White River area is dominated by Miocene age volcanics of andesite to rhyolite composition, which may be in part coeval with plutonic phases of the nearby 26 - 14 m.y. Tatoosh batholith. These volcanic rocks host two spatially distinct and gold-bearing epithermal deposits of the acid-sulfate type that are structurally, temporally, and genetically related to the formation and resurgent magmatic activity at the margin of an early Miocene caldera (22.6 - 19.1 m.y.). The age of hydrothermal activity is 20.4 +/- 0.1 m.y. based on UAr/TZAr analysis of hypogene alunite from the mineralized zone. Hydrothermal alteration and metallization of both deposits is chemically and mineralogically similar and consists of a central core of pervasive silicification that grades outward into zones of advanced argillic, argillic, and propylitic alteration. The largest of the two target areas is defined by a silica capping. Sulfur isotope analyses of cogenetic alunite-pyrite-enargite demonstrate a (34)S of +28.8 per thousand for the alunite-pyrite mineral pair. This large fractionation corroborates other field and mineralogic evidence for the hypogene origin of the alunite, and provides a geologically reasonable isotopic temperature estimate of 190 C for this epithermal deposit. Fold was introduced in at least 3 distinct episodes of structural-hydrothermal activity. The highest concentration of gold is within a zone measuring 1600 by 300-600 feet, and is localized in parts of the similar capping that contain outcrops of matrix-supported explosion breccias and veins having anomalous concentrations of up to 480 ppb Au, 13.7 ppm Ag, 1900 ppm As, 213 ppm Sb, 7.5 ppm Hg, and 10 ppm Mo.

    This map shows the geology of 675 km2 (260 mi2) on the west slope of the Sierra Nevada, California, mainly in Sequoia National Park and Sequoia National Forest. It was produced by the U.S. Geological Survey (USGS) at the request of the National Park Service to complete the geologic map coverage of Kings Canyon and Sequoia National Parks. The area includes the Mineral King 15’ topographic quadrangle (sheet 1) and strips along the east and northeast edges of the Kaweah 15’ topographic quadrangle (sheet 2), both in Tulare County. Mapping was performed mainly on the 1:24,000-scale Mineral King, Silver City, Quinn Peak, Moses Mountain, Case Mountain, and Dennison Peak 7.5’ topographic quadrangle bases. Rocks within the study area are chiefly Cretaceous granites and granodiorites of the Sierra Nevada batholith that intruded coherent masses of Mesozoic metasedimentary and metavolcanic rocks. Quaternary till and talus are the principal surficial deposits, with the exception of a large bouldery alluvial apron near the southwest corner of the map area. The study area includes the headwaters of the Kaweah River (East and South Forks), Tule River (North Fork and North Fork of the Middle Fork), and the Little Kern River. Relief is considerable, with elevations spanning from 1,500 feet along the Middle Fork Kaweah River to 12,432 feet at the summit of Florence Peak along the crest of the Great Western Divide.

    This study examined echinoderm assemblages from nearshore rocky habitats for large-scale distribution patterns with specific emphasis on identifying latitudinal trends and large regional hotspots. Echinoderms were sampled from 76 globally-distributed sites within 12 ecoregions, following the standardized sampling protocol of the Census of Marine Life NaGISA project (www.nagisa.coml.org). Sample-based species richness was overall low (<1–5 species per site), with a total of 32 asteroid, 18 echinoid, 21 ophiuroid, and 15 holothuroid species. Abundance and species richness in intertidal assemblages sampled with visual methods (organisms >2 cm in 1 m2 quadrats) was highest in the Caribbean ecoregions and echinoids dominated these assemblages with an average of 5 ind m?2. In contrast, intertidal echinoderm assemblages collected from clearings of 0.0625 m2 quadrats had the highest abundance and richness in the Northeast Pacific ecoregions where asteroids and holothurians dominated with an average of 14 ind 0.0625 m?2. Distinct latitudinal trends existed for abundance and richness in intertidal assemblages with declines from peaks at high northern latitudes. No latitudinal trends were found for subtidal echinoderm assemblages with either sampling technique. Latitudinal gradients appear to be superseded by regional diversity hotspots. In these hotspots echinoderm assemblages may be driven by local and regional processes, such as overall productivity and evolutionary history. We also tested a set of 14 environmental variables (six natural and eight anthropogenic) as potential drivers of echinoderm assemblages by ecoregions. The natural variables of salinity, sea-surface temperature, chlorophyll a, and primary productivity were strongly correlated with echinoderm assemblages; the anthropogenic variables of inorganic pollution and nutrient contamination also contributed to correlations. Our results indicate that nearshore echinoderm assemblages appear to be shaped by a network of environmental and ecological processes, and by the differing responses of various echinoderm taxa, making generalizations about the patterns of nearshore rocky habitat echinoderm assemblages difficult.

  19. Modeling near-shore subsea permafrost degradation in the Laptev Sea

    NASA Astrophysics Data System (ADS)

    Kneier, F.; Langer, M.; Overduin, P. P.

    2012-12-01

    Most subsea permafrost in the Arctic Ocean shelf regions is relict terrestrial permafrost that was inundated by sea water by rising sea levels after the last glacial period. Permafrost usually degrades offshore under the influence of sea-bottom temperatures, salt infiltration and a wide range of near-shore coastal processes. Subsea permafrost instability has important potential implications due to the release of methane to the atmosphere and by increasing coastal erosion rates. Our objectives are to employ meso-scale numerical calculations (from meter to kilometer, 1000s of years) in connection with borehole data from the Laptev Sea to model the transition of permafrost from onshore to offshore conditions. The goal is to identify key processes driving permafrost degradation in the near-shore zone of the shelf. The heat transfer equation is solved numerically taking into account freeze-thaw processes in a three-phase heat capacity / conductivity model. Sediment composition and initial temperature profiles are derived from field and laboratory analysis of the borehole data. Our approach neglects some processes such as solute diffusion, but includes the effect of pore water salinity on phase state and thermal properties. Measured temperature profiles are compared to the modeled subsea soil temperature evolution over the course of the 2500 year transgression of the farthest offshore borehole in the transect. The degradation of the ice-bearing permafrost table or thaw depth is of special interest due to its direct relation to sediment stability and as the most readily discernible feature in the field observations. Temperature profiles generally agree well with model calculations reproducing the almost isothermal permafrost profiles currently observed, but show more variation potentially partially caused by drilling disturbances. The thaw depth is mainly driven by salt contamination and infiltration into deeper pore water with time. Complicating near-shore processes discussed include the occurrence of bottom-fast sea ice and marine sedimentation rates.

    Nonconservative fluxes of dissolved nutrients (Si, N and P) in groundwater and nearshore ocean water off two golf courses (Keauhou and Waikoloa) on the west coast of Hawaii were estimated using a one-dimensional mixing model. Groundwater flowing under the Keauhou course discharges into a semi-enclosed embayment with restricted circulation. Leaching of 10% of the N from golf course fertilizer accounted for an increase in groundwater N flux to the bay of 116%; leaching of 1% of the P from fertilizer accounted for an increase in groundwater P flux of 22%. Uptake of Si, N and P was not measurable within the bay; a buoyant surface layer (1 m thick) did not come into contact with benthic communities, and nutrient uptake by plankton was limited to no greater than 2% of the N and P delivered by groundwater flux. At Waikoloa, leaching of N and P from golf course fertilizers accounted for an increase in groundwater nutrient flux to brackish ponds near the coastline of 229% and 400%, respectively. Waikoloa is located on an exposed coastline with substantial turbulent mixing throughout the water column. Nutrient subsidies from golf course fertilizers were not distinguishable from natural groundwater input, and uptake of N in the nearshore zone equaled 80% of the groundwater flux at the shoreline. On a mass delivery basis, natural and anthropogenic nutrient fluxes to the nearshore ocean appear sufficient to cause alteration to community function and structure. Such effects, however, are not solely responses to nutrient loading. Consideration of physical processes, along with use of conservative tracers can provide a practical method for quantifying these effects of man's activities on the ocean.

    Shrimp trawling is common throughout the southeastern and Gulf of Mexico coasts of the USA and is the primary contributor to fisheries discards in these regions. Tens of thousands of nearshore seabirds nest near shrimp trawling grounds in the USA, but to date, there has been no assessment of the relationship between seabirds and shrimp trawlers. We examined the taxonomic composition of bycatch, rate at which seabirds scavenged bycatch, and energy density of discarded bycatch in a nearshore commercial shrimp fishery. Bycatch was primarily comprised of demersal fish that are not typically accessible to the plunge-diving and surface-feeding seabirds that occur in the area. Hence, seabird diets in the region appear to be broadened taxonomically by the availability of discards. Results from discard experiments indicated that 70% of the nearly 5,500 items discarded by hand were scavenged by seabirds and that the fate of a discarded item was most strongly predicted by its taxonomic order. Laughing gulls scavenged the greatest proportion of discards, although brown pelicans were the only species to scavenge more discards than predicted based upon their abundance. Because this is the first such study in the region, it is difficult to ascertain the extent or intensity of the impact that discards have on nearshore seabirds. Nonetheless, our results suggest that it will be difficult for managers to clearly understand fluctuations in local seabird population dynamics without first understanding the extent to which these species rely upon discards. This may be especially problematic in situations where seabird populations are recovering following natural or anthropogenic stressors. ?? 2011 Springer-Verlag.

  2. Wave-induced mass transport affects daily Escherichia coli fluctuations in nearshore water

    Characterization of diel variability of fecal indicator bacteria concentration in nearshore waters is of particular importance for development of water sampling standards and protection of public health. Significant nighttime increase in Escherichia coli (E. coli) concentration in beach water, previously observed at marine sites, has also been identified in summer 2000 from fixed locations in waist- and knee-deep waters at Chicago 63rd Street Beach, an embayed, tideless, freshwater beach with low currents at night (approximately 0.015 m s–1). A theoretical model using wave-induced mass transport velocity for advection was developed to assess the contribution of surface waves to the observed nighttime E. coli replenishment in the nearshore water. Using average wave conditions for the summer season of year 2000, the model predicted an amount of E. coli transported from water of intermediate depth, where sediment resuspension occurred intermittently, that would be sufficient to have elevated E. coli concentration in the surf and swash zones as observed. The nighttime replenishment of E. coli in the surf and swash zones revealed here is an important phase in the cycle of diel variations of E. coli concentration in nearshore water. According to previous findings in Ge et al. (Environ. Sci. Technol. 2010, 44, 6731–6737), enhanced current circulation in the embayment during the day tends to displace and deposit material offshore, which partially sets up the system by the early evening for a new period of nighttime onshore movement. This wave-induced mass transport effect, although facilitating a significant base supply of material shoreward, can be perturbed or significantly influenced by high currents (orders of magnitude larger than a typical wave-induced mass transport velocity), current-induced turbulence, and tidal forcing.

  3. Atmospheric NO2 dynamics and impact on ocean color retrievals in urban nearshore regions

    Urban nearshore regions are characterized by strong variability in atmospheric composition, associated with anthropogenic emissions and meteorological processes that influence the circulation and accumulation of atmospheric pollutants at the land-water interface. If not adequately corrected in satellite retrievals of ocean color, this atmospheric variability can impose a false impression of diurnal and seasonal changes in nearshore water quality and biogeochemical processes. Consideration of these errors is important for measurements from polar orbiting ocean color sensors but becomes critical for geostationary satellite missions having the capability for higher frequency and higher spatial resolution observations of coastal ocean dynamics. We examined variability in atmospheric NO2 over urban nearshore environments in the Eastern US, Europe, and Korea, using a new network of ground-based Pandora spectrometers and Aura-OMI satellite observations. Our measurements in the US and in Europe revealed clear diurnal and day-of-the-week patterns in total column NO2 (TCNO2), temporal changes as large as 0.8 DU within 4 h, and spatial variability as large as 0.7 DU within an area often covered by just a single OMI pixel. TCNO2 gradients were considerably stronger over the coastal cities of Korea. With a coarse resolution and an overpass at around 13:30 local time, OMI cannot detect this strong variability in NO2, missing pollution peaks from industrial and rush hour activities. Observations were combined with air quality model simulations and radiative transfer calculations to estimate the impact of atmospheric NO2 variability on satellite retrievals of coastal ocean remote sensing reflectance and biogeochemical variables (i.e., chlorophyll and CDOM).

    Over the past decade, evidence of abrupt latitudinal changes in the dynamics, structure and genetic variability of intertidal and subtidal benthic communities along central-northern Chile has been found consistently at 30–32°S. Changes in the advective and thermal environment in nearshore waters have been inferred from ecological patterns, since analyses of in situ physical data have thus far been missing. Here we analyze a unique set of shoreline temperature data, gathered over 4–10 years at 15 sites between 28–35°S, and combine it with satellite-derived winds and sea surface temperatures to investigate the latitudinal transition in nearshore oceanographic conditions suggested by recent ecological studies. Our results show a marked transition in thermal conditions at 30–31°S, superimposed on a broad latitudinal trend, and small-scale structures associated with cape-and-bay topography. The seasonal cycle dominated temperature variability throughout the region, but its relative importance decreased abruptly south of 30–31°S, as variability at synoptic and intra-seasonal scales became more important. The response of shoreline temperatures to meridional wind stress also changed abruptly at the transition, leading to a sharp drop in the occurrence of low-temperature waters at northern sites, and a concurrent decrease in corticated algal biomass. Together, these results suggest a limitation of nitrate availability in nearshore waters north of the transition. The localized alongshore change results from the interaction of latitudinal trends (e.g., wind stress, surface warming, inertial period) with a major headland-bay system (Punta Lengua de Vaca at 30.25°S), which juxtaposes a southern stretch of coast characterized by upwelling with a northern stretch of coast characterized by warm surface waters and stratification. This transition likely generates a number of latitude-dependent controls on ecological processes in the nearshore that can explain species-specific effects, and add strength to the suggestion of an oceanography-driven, major spatial transition in coastal communities at 30–31°S.

    The benthic aquatic organisms in the near-shore environment of the Columbia River are the first biological receptors that can be exposed to groundwater contaminants coming from the U.S. Department of Energy's Hanford Site. The primary contaminant of concern in the former nuclear fuels processing area at the Site, known as the 300 Area, is uranium. Currently, there are no national clean up criteria for uranium and ecological receptors. This report summarizes efforts to characterize biological uptake of uranium in the food chain of the benthic aquatic organisms and provide information to be used in future assessments of uranium and the ecosystem.

    Extreme fluctuations or events are often associated with power law statistics. Indeed, it is a popular belief that "wild randomness'' is deeply associated with distributions with power law tails characterized by small exponents. In other words, power law tails are often seen as the epitome of extreme events (the "Black Swan'' story). Here, we document in very different systems that there is life beyond power law tails: power laws can be superseded by "dragon-kings'', monster events that occur beyond (or changing) the power law tail. Dragon-kings reveal hidden mechanisms that are only transiently active and that amplify the normal fluctuations (often described by the power laws of the normal regime). The goal of this lecture is to catalyze the interest of the community of geophysicists across all fields of geosciences so that the "invisible gorilla" fallacy may be avoided. Our own research illustrates that new statistics or representation of data are often necessary to identify dragon-kings, with strategies guided by the underlying mechanisms. Paradoxically, the monsters may be ignored or hidden by the use of inappropriate analysis or statistical tools that amount to cut a mamooth in small pieces, so as to lead to the incorrect belief that only mice exist. In order to stimulate further research, we will document and discuss the dragon-king phenomenon on the statistics of financial losses, economic geography, hydrodynamic turbulence, mechanical ruptures, avalanches in complex heterogeneous media, earthquakes, and epileptic seizures. The special status of dragon-kings open a new research program on their predictability, based on the fact that they belong to a different class of their own and express specific mechanisms amplifying the normal dynamics via positive feedbacks. We will present evidence of these claims for the predictions of material rupture, financial crashes and epileptic seizures. As a bonus, a few remarks will be offered at the end on how the dragon-king phenomenon allows us to understand the present World financial crisis as underpinned in two decades of successive financial and economic bubbles, inflating the mother of all bubbles with new monster dragon-kings at the horizon. The consequences in terms of a new "normal" are eye-opening. Ref: D.

    Imogene King's Theory of Goal Attainment provides a schema for nurses interested in functional status. However, the lack of a uniform definition for functional status has hindered development of a concise understanding of this phenomenon. Functional status is particularly important to nurses who are concerned with the safety and wellbeing of clients. With healthcare's increased focus on client-family-centered care it is important to develop innovative approaches for evaluating functional status that incorporate the client-family perspective. King's focus on mutual decision-making is an underutilized resource that can provide great insight into the study and understanding of functional status. PMID:25805388

    Past operations at the Hanford Site 100-N Area reactor resulted in the release of radiological contaminants to the soil column, local groundwater, and ultimately to the near-shore environment of the Columbia River. In September 1997, the Washington State Department of Health (WDOH) and the Hanford Site Surface Environmental Surveillance Project (SESP) initiated a special study of the near-shore vicinity at the Hanford Site`s retired 100-N Area reactor. Environmental samples were collected and analyzed for radiological contaminants ({sup 3}H, {sup 90}Sr, and gamma/ emitters), with both the WDOH and SESP analyzing a portion of the samples. Samples of river water, sediment, riverbank springs, periphyton, milfoil, flying insects, clam shells, and reed canary grass were collected. External exposure rates were also measured for the near-shore environment in the vicinity of the 100-N Area. In addition, samples were collected at background locations above Vernita Bridge.

  11. Queen Conch (Strombus gigas) Testis Regresses during the Reproductive Season at Nearshore Sites in the Florida Keys

    Spade, Daniel J.; Griffitt, Robert J.; Liu, Li; Brown-Peterson, Nancy J.; Kroll, Kevin J.; Feswick, April; Glazer, Robert A.; Barber, David S.; Denslow, Nancy D.

    Background Queen conch (Strombus gigas) reproduction is inhibited in nearshore areas of the Florida Keys, relative to the offshore environment where conchs reproduce successfully. Nearshore reproductive failure is possibly a result of exposure to environmental factors, including heavy metals, which are likely to accumulate close to shore. Metals such as Cu and Zn are detrimental to reproduction in many mollusks. Methodology/Principal Findings Histology shows gonadal atrophy in nearshore conchs as compared to reproductively healthy offshore conchs. In order to determine molecular mechanisms leading to tissue changes and reproductive failure, a microarray was developed. A normalized cDNA library for queen conch was constructed and sequenced using the 454 Life Sciences GS-FLX pyrosequencer, producing 27,723 assembled contigs and 7,740 annotated transcript sequences. The resulting sequences were used to design the microarray. Microarray analysis of conch testis indicated differential regulation of 255 genes (p<0.01) in nearshore conch, relative to offshore. Changes in expression for three of four transcripts of interest were confirmed using real-time reverse transcription polymerase chain reaction. Gene Ontology enrichment analysis indicated changes in biological processes: respiratory chain (GO:0015992), spermatogenesis (GO:0007283), small GTPase-mediated signal transduction (GO:0007264), and others. Inductively coupled plasma-mass spectrometry analysis indicated that Zn and possibly Cu were elevated in some nearshore conch tissues. Conclusions/Significance Congruence between testis histology and microarray data suggests that nearshore conch testes regress during the reproductive season, while offshore conch testes develop normally. Possible mechanisms underlying the testis regression observed in queen conch in the nearshore Florida Keys include a disruption of small GTPase (Ras)-mediated signaling in testis development. Additionally, elevated tissue levels of Cu (34.77 ng/mg in testis) and Zn (831.85 ng/mg in digestive gland, 83.96 ng/mg in testis) nearshore are similar to reported levels resulting in reproductive inhibition in other gastropods, indicating that these metals possibly contribute to NS conch reproductive failure.

    1983-01-01

    Ichthyoplankton was collected at 17 nearshore (bottom depth greater than or equal to 5 m but less than or equal to 10 m) sites in western Lake Huron during 1973-75 with a 0.5-m net of 351-micron mesh towed at 99 m/min. Larvae of rainbow smelt (Osmerus mordax) dominated late spring and early summer catches and larvae of alewives (Alosa pseudoharengus) the midsummer catches. Larval yellow perch (Perca flavescens) were caught in early summer but were rarely the dominant species. The time of spawning and hatching, and thus occurrence of larvae, differed between areas but was less variable for alewives than for yellow perch. The appearance of larvae in Saginaw Bay was followed successively by their appearance in southern, central, and northern Lake Huron. Rainbow smelt were most abundant in northern Lake Huron and yellow perch and alewives in inner Saginaw Bay. Densities of either rainbow smelt or alewives occasionally exceeded 1/mA?, whereas those of yellow perch never exceeded 0.1/mA?. Abundance of alewives was usually highest 1 to 3 m beneath the surface and that of rainbow smelt 2 to at least 6 m beneath the surface. Important nursery areas of rainbow smelt were in bays and off irregular coastlines and those of yellow perch were in bays. All nearshore waters seemed equally important as nursery areas of alewives.

  14. Error Evaluation of Near-shore Bathymetry Using the Single Beam Echo Sounder

    2013-12-01

    By using the single-beam echo sounder or the multi-beam echo sounder to investigate the near-shore bathymetry, its measurement has been limited by a series of errors caused by positioning, vehicle's attitude, acoustic speed variation, and some others. The main problem of bathymetry by using single-beam echo sounder is from lack of full coverage of the sounding beams illuminating the survey area of interesting. In addition, in the every ends of the survey lines especially when approaching the coast line, the turning will cause ship tilt to one side making a predicted but uncorrectable error. It is the reason that surveyors will choose a multi-beam echo sounder for the measurement when bathymetry coverage and accuracy are considered. However, at shallow depths less than 5 meters, as example, the high risk of multi-beam's transducers colliding with the ocean bottom will lower the willingness in using a multi-beam sounder due to high-priced of the transducers. Therefore, the single beam sounders have been the main instrument to measure near-shore under water topography in the industry. This study is to understand sounding deviation causing by the turning of the survey ship, such that we can analyze and control the errors to improve the accuracy of measurement using the single beam echo sounder in the shallow waters.

    High-frequency measurements of stratified turbulence throughout the water column were collected over a 2 week period in the nearshore environment of southern Monterey Bay, CA, using a cabled observatory system and an underwater turbulence flux tower. The tower contained a vertical array of acoustic Doppler velocimeters and fast-response conductivity-temperature sensors, providing a nearly continuous data set of turbulent velocity and density fluctuations and a unique look into the stratified turbulence field. The evolution of various turbulence quantities and direct measurements of the vertical turbulent diffusivity is examined in the presence of nearshore internal bores, both in the near-bed region and in the stratified interior. We show that individual bores can drive substantial changes in local turbulence and mixing dynamics, with considerable differences between the leading and trailing edges of the bores. Using direct observations of the flux Richardson number, our measurements confirm previous observations that show the highest mixing efficiencies (?) occurring in regions of buoyancy-controlled turbulence. Parameterizations of the flux Richardson number as a function of the turbulence activity number are also presented. Finally, we demonstrate that the commonly used assumption of a constant mixing efficiency (? = 0.2) for calculating turbulent diffusivities leads to significant overestimates compared to diffusivity values calculated using the directly measured mixing efficiency. Implications of the results are discussed.

    We use detailed diet analyses of the predominant planktivorous, benthivorous and piscivorous fish species from Lake Superior to create a nearshore (bathymetric depths Mysis diluviana and Diporeia spp). Although the piscivorous fishes like lean lake trout (Salvelinus namaycush) fed to a lesser extent on Diporeia and Mysis, they were still strongly connected to these macroinvertebrates, which were consumed by their primary prey species (sculpin spp., rainbow smelt Osmerus mordax, and coregonines). The addition of Bythotrephes to summer/fall cisco and lake whitefish diets, and the decrease in rainbow smelt in lean lake trout diets (replaced by coregonines) were the largest observed differences relative to historic Lake Superior diet studies. Although the offshore food web of Lake Superior was simpler than nearshore in terms of number of fish species present, the two areas had remarkably similar food web structures, and both fish communities were primarily supported by Mysis and Diporeia. We conclude that declines in Mysis or Diporeia populations would have a significant impact on energy flow in Lake Superior. The food web information we generated can be used to better identify management strategies for Lake Superior.

    Nearshore dredge disposal was performed during the summer of 2005 at Ocean Beach, San Francisco, CA, a high energy tidal and wave environment. This trial run was an attempt to provide a buffer to a reach of coastline where wave attack during the winter months has had a severe impact on existing sewage infrastructure. Although the subsequent beach response was inconclusive, after one year the peak of the disposal mound had migrated ~100 m toward the shore, providing evidence that annual dredge disposal at this site could be beneficial over the long-term by at the very least providing: 1) additional wave dissipation during storms 2) compatible sediment to feed nearshore bars, 3) sediment cover on an exposed sewage outfall pipe, and 4) a viable alternative to the shoaling offshore disposal site. Numerical modeling suggests that despite the strong tidal currents in the region, wave forcing is the dominant factor moving the sediment slowly toward shore, and placing sediment at just slightly shallower depths (e.g. 9 m) in the future would have a more immediate impact.

  18. Determination of dominant nearshore hydrodynamic forcing adjacent to a tidal inlet and submerged artificial reef

    NASA Astrophysics Data System (ADS)

    Herrington, Thomas Oliver, Jr.

    An 18 month field monitoring program was conducted to determine the impact of a submerged narrow crested artificial reef, located seaward of the surf zone and immediately adjacent to a tidal inlet, on nearshore beach profile evolution. Observed structure settlement and scour zones adjacent to the structure are analyzed though the use of wind, wave, current, and tidal measurements obtained over two independent time periods, each of one week duration. Complex interactions of wind, wave, and tidal elevation were found to generate a flood dominated current structure in the vicinity of the reef. Due to the complexity of the forcing mechanisms a qualitative analysis of the impact of the structure on nearshore hydrodynamics was performed. The structure was found to reduce the magnitude of the near bottom cross-shore currents. However, structure-induced vertical currents combined with flood dominant tidal currents provides a mechanism to initiate near-structure scour and settlement. In an effort to quantitatively analyze the fluid-structure interactions, a methodology was developed to determine the relative magnitudes of the measured wind, wave, and tidal forcings. The frequency distribution of energy density in the tidal elevation and current records provides insight into nonlinear interactions present in the data set. Decomposing the record into independent forcing terms allowed the development of an empirical model which indicates that linear and nonlinear interactions between the wave amplitude and water depth were found to dominate the forcing of the observed currents.

    1983-01-01

    A new data-acquisition system capable of measuring waves, currents and the nearshore profile in breaking waves as high as 5 m has been developed and successfully field-tested. Components of the mechanical system are a sled carrying a vertical mast, a double-drum winch placed landward of the beach, and a line that runs from one drum of the winch around three blocks, which are the corners of a right triangle, to the other drum of the winch. The sled is attached to the shore-normal side of the triangular line arrangement and is pulled offshore by one drum of the winch and onshore by the other. The profile is measured as the sled is towed along the shore-normal transect using an infrared rangefinder mounted landward of the winch and optical prisms mounted on top of the sled's mast. A pressure sensor and two-axis electromagnetic current meter are mounted on the frame of the sled. These data are encoded on the sled and telemetered to a receiving/recording station onshore. Preliminary results suggest that near-bottom offshore-flowing currents during periods of high-energy swell are important in forcing changes to the configuration of the nearshore profile. ?? 1983.

    The North American population of king eiders (Somateria spectabilis) has declined by more than 50% since the late 1970s for unknown reasons. King eiders spend most of their lives in remote areas, forcing managers to make regulatory and conservation decisions based on very little information. We incorporated available published estimates of vital rates with new estimates to build a female, stage-based matrix population model for king eiders and examine the processes underlying population dynamics of king eiders breeding at 2 sites, Teshekpuk and Kuparuk, on the coastal plain of northern Alaska and wintering around the Bering Sea (2001–2010). We predicted a decreasing population (? = 0.981, 95% CI: 0.978–0.985), and that population growth was most sensitive to changes in adult female survival (sensitivity = 0.92). Low duckling survival may be a bottleneck to productivity (variation in ducking survival accounted for 66% of retrospective variation in ?). Adult survival was high (0.94) and invariant (? = 0.0002, 95% CI: 0.0000–0.0007); however, catastrophic events could have a major impact and we need to consider how to mitigate and manage threats to adult survival. A hypothetical oil spill affecting breeding females in a primary spring staging area resulted in a severe population decline; although, transient population dynamics were relatively stable. However, if no catastrophic events occur, the more variable reproductive parameters (duckling and nest survival) may be more responsive to management actions.

    To determine the effect of Avermectin (AVM) on inflammation damage in king pigeon brain, eighty two-month-old American king pigeons were randomly divided into four groups, and were fed with either commercial diet or AVM-supplemented diet containing 20 mg kg(-1)diet, 40 mg kg(-1)diet, and 60 mg kg(-1)diet AVM for 30, 60 and 90 d, respectively. Then, the expression level of inflammatory factors (iNOS, PTGEs, NF-?B), histological damage, and ultra-structural damage were examined. It showed that AVM caused higher expressions (P<0.05) of iNOS, PTGEs, NF-?B with disorganized histological and ultra-structural structures in cerebrum, cerebellum, and optic lobe. Meanwhile, inflammatory and histopathological damage were induced by AVM in king pigeon brains. In addition, the main targeted organelle in nervous system was mitochondria, which indicated that mitochondria may be relevant to the process of inflammation induced by AVM. To our best knowledge, this is the first report to study the toxic effect of AVM on inflammatory damage in king pigeon. Thus, the information presented in this study is believed to be helpful in supplementing data for further AVM toxicity study. PMID:24134892

    KING crabs (Family Lithodidae) are among the world's largest arthropods, having a crab-like morphology and a strongly calcified exoskeleton1-6. The hermit crabs, by contrast, have depended on gastropod shells for protection for over 150 million years5,7. Shell-living has constrained the morphological evolution of hermit crabs by requiring a decalcified asymmetrical abdomen capable of coiling into gastropod shells and by preventing crabs from growing past the size of the largest available shells1-6. Whereas reduction in shell-living and acquisition of a crab-like morphology (carcinization) has taken place independently in several hermit crab lineages, and most dramatically in king crabs1-6, the rate at which this process has occurred was entirely unknown2,7. We present molecular evidence that king crabs are not only descended from hermit crabs, but are nested within the hermit crab genus Pagurus. We estimate that loss of the shell-living habit and the complete carcinization of king crabs has taken between 13 and 25 million years.

  19. Influence of the sea-ice edge on the Arctic nearshore environment

    NASA Astrophysics Data System (ADS)

    Coasts form the dynamic interface of the terrestrial and oceanic systems. In the Arctic, and in much of the world, the coast is a zone of relatively high population, infrastructure, biodiversity, and ecosystem services. A significant difference between Arctic and temperate coasts is the presence of sea ice. Sea ice influences Arctic coasts in two main ways: (1) the length of the sea ice-free season controls the length of time over which nearshore water can interact with the land, and (2) the sea ice edge controls the fetch over which storm winds can blow over open water, resulting in changes in nearshore water level and wave field. The resulting nearshore hydrodynamic environment impacts all aspects of the coastal system. Here, we use satellite records of sea ice along with a simple model for wind-driven storm surge and waves to document how changes in the length and character of the sea ice-free season have impacted the nearshore hydrodynamic environment. For our sea ice analysis we primarily use the Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS. We make whole-Arctic maps of sea ice change in the coastal zone. In addition to evaluating changes in length of the sea ice-free season at the coast, we look at changes segmented by azimuth. This allows us to consider changes in the sea ice in the context of the wind field. For our storm surge and wave field analysis we focus on the Beaufort Sea region. This region has experienced some of the greatest changes in both sea ice cover and coastal erosion rates in the Arctic and is anticipated to experience significant change in the future. In addition, the NOAA ESRL GMD has observed the wind field at Barrow since extends to 1977. In our past work on the rapid and accelerating coastal erosion, we have shown that one may model storm surge with a 2D numerical bathystrophic model, and that waves are well represented by the Shore Protection Manual methods for shallow-water fetch-limited waves. We use these models to explore the effect of increasing fetch on water level set up and wave generation. As increasing the fetch is one of the main effects of the changing sea ice cover, this allows us to connect changes in the sea ice cover to changes in the nearshore hydrodynamic environment. The long wind record allows for us to investigate changes in extreme wind and associated storm events. Preliminary analysis of Barrow and Drew Point indicate that at Drew Point the sea ice-free season has expanded by ˜17 days/decade while at Barrow it has expanded by ˜22 days/decade. We find the increase in the number of days when the sea ice edge is far away from the coast makes up a large proportion of the total increase in the duration of the sea ice-free season. For these days the sea ice edge does not provide a limit on the fetch over which water level set up and waves are generated.

    Heng?Gu?Gu?Shang?Yu?He?Ji, also known as OsteoKing, is used as a herbal Traditional Chinese Medicine for the treatment of bone disease, including femoral head necrosis and osteoarthritis. However, whether OsteoKing has anti?osteoporotic properties has remained to be elucidated. The purpose of the present study was therefore to investigate the effects of OsteoKing on ovariectomy?induced osteoporosis in rabbits. Female New Zealand white rabbits were randomly divided into an ovariectomized (OVX) group and a sham?surgery group. The rabbits in the OVX group were subjected to an ovariectomy, while the rabbits in the sham group were subjected to the removal of an area of fat near the two ovaries. Bone mineral density, mechanical properties, serum biochemical parameters and micro?architecture were examined at 150 days post?OVX to characterize the experimental animal model. Once the osteoporotic rabbit model had been established, the rabbits in the OVX group were divided into the following groups: Model group, nilestriol group and 300 and 600 mg/kg OsteoKing groups, containing 16 rabbits in each group. OsteoKing and nilestriol were administered orally. The bone mineral density, mechanical properties, serum biochemical parameters, histology and micro?architecture were examined using dual?energy X?ray absorptiometric analysis, mechanical assessments, enzyme?linked immunosorbent assays, histopathological evaluation and micro?computerized tomography examination following 60 days and 120 days of treatment, respectively. Treatment with OsteoKing led to an elevation in the bone mineral density of the vertebra and serum phosphorus levels, reduced serum concentrations of osteocalcin, procollagen type ? N?terminal peptide, tartrate?resistant acid phosphatase 5b and cross?linked N?telopeptide of type ? collagen, improved mechanical properties (maximum load, stiffness and energy absorption capacity), and micro?architecture of the lumbar vertebra in the OVX osteoporotic rabbit model following treatment for 120 days. In conclusion, it was demonstrated that OsteoKing is effective in the prevention of estrogen deficiency?associated bone loss and may be a promising drug for the treatment of post?menopausal osteoporosis.

    Each summer, the nuisance green alga Cladophora (mostly Cladophora glomerata) amasses along Lake Michigan beaches, creating nearshore anoxia and unsightly, malodorous mats that can attract problem animals and detract from visitor enjoyment. Traditionally, elevated counts of Escherichia coli are presumed to indicate the presence of sewage, mostly derived from nearby point sources.

    The nearshore circulation induced by a focused pattern of surface gravity waves is studied at a beach adjacent to a major inlet with a large ebb tidal shoal. Using a coupled wave and wave-averaged nearshore circulation model, it is found that the nearshore circulation is significantly affected by the heterogeneous wave patterns caused by wave refraction over the ebb tidal shoal. The model is used to predict waves and currents during field experiments conducted near the mouth of San Francisco Bay and nearby Ocean Beach. The field measurements indicate strong spatial variations in current magnitude and direction and in wave height and direction along Ocean Beach and across the ebb tidal shoal. Numerical simulations suggest that wave refraction over the ebb tidal shoal causes wave focusing toward a narrow region at Ocean Beach. Due to the resulting spatial variation in nearshore wave height, wave-induced setup exhibits a strong alongshore nonuniformity, resulting in a dramatic change in the pressure field compared to a simulation with only tidal forcing. The analysis of momentum balances inside the surf zone shows that, under wave conditions with intensive wave focusing, the alongshore pressure gradient associated with alongshore nonuniform wave setup can be a dominant force driving circulation, inducing heterogeneous alongshore currents. Pressure-gradient-forced alongshore currents can exhibit flow reversals and flow convergence or divergence, in contrast to the uniform alongshore currents typically caused by tides or homogeneous waves.

    The western margin of the Gulf of Maine is a bedrock-framed, glaciated continental shelf that has only recently been geologically mapped. The bathymetry is divisible into four physiographic areas: nearshore basins, shelf valleys, rocky zones, and outer basins. The nearshore basins are largely floored by mud except near rock outcrops where shelly gravel occurs. Shelf valleys extend seaward from nearshore basins and estuaries and generally possess less sediment than nearshore basins. Abundant exposures of Pleistocene sediment with rippled substrates suggest that contemporary reworking is occurring. Rocky zones are the most abundant physiographic area and include both exposed bedrock and glacial gravel outcrops. Shell material produced by organisms living on or near rocks is common both in the rocky zones and in abutting environments. The outer basin begins at a depth of about 60 m and extends beyond the 100 m isobath. This area is occasionally bordered on its landward side by the late Quaternary lowstand shoreline. Below this shoreline thicker deposits of sediment exist, while all environments landward were reworked by a regression and transgression of the sea. ?? 1991.

    An experiment conducted in late March of 2001 along the beaches and nearshore of Santa Cruz, California consisted of three phases: pre-experiment, experiment, and post-experiment. In the pre- and post-experimental phases, high-resolution side scan sonar and multibeam bathymetry data were collected to produce maps describing surface sediments and depth changes of the seafloor near the Santa Cruz Harbor. Offshore and beach sediment samples were collected three weeks prior to and after the experiment to analyze for changes in grain size and to provide physical evidence of seafloor substrate. Experimental monitoring consisted of daily beach and offshore sediment sampling. Oceanographic data including swell direction, height, and period were obtained from buoys offshore. Rainfall and stream flow data from the nearby San Lorenzo River were recorded during all phases of the project. Our sedimentological studies of materials dredged from the upper Santa Cruz Harbor, California suggest that sediment containing approximately 40% sand and 60% mud can be disposed in the surf zone without adversely affecting the quality of neighboring beaches or offshore rocky habitats while simultaneously replenishing sand to eroding beaches downcoast. A small amount of the mud-rich material (about 2300 m3) was placed into the surf-zone during the winter of 2000-2001 to determine the retention of sands in the nearshore zone and the impact that fine-grain (mud) sediment may have on rocky habitats. The beaches and other nearshore environments near the disposal site of the Santa Cruz Small Craft Harbor appear to be unchanged by the disposed harbor sediments. The data indicates that little change in sediment grain size or distribution has occurred. This is most likely due to the high-energy nature of this coastline, which results in suspension of silts and clays until they reach lower energy, deeper water offshore outside of the study area. The sand fraction of the disposed sediment was likely transported to the southeast in littoral drift and may replenish downcoast beaches.

  2. Influence of tides and waves on the fate of nutrients in a nearshore aquifer: Numerical simulations

    A numerical investigation is presented that demonstrates the influence of tides and waves on the transport and transformation of nutrients (NO3-, NH4+, PO43-) in a homogeneous unconfined nearshore aquifer and subsequent fluxes to the sea. Simulations of an aquifer subject to semi-diurnal tides and constant waves acting on a sloping beach face were conducted using SEAWAT-2005 combined with PHT3D v2.10. Tidal amplitude (A) and wave height (Hrms) varying from 0.25 to 0.75 m and 1 to 2 m, respectively, were examined. Results show that tides and waves modify the subsurface discharge pathway of land-derived nutrients by changing the nearshore groundwater flow dynamics. More importantly, the oceanic forcing impacts nutrient cycling as it causes significant seawater exchange (along with dissolved O2 and organic matter) across the aquifer-ocean interface. Although steady wave forcing caused higher seawater influx, tides led to greater seawater-freshwater mixing in the nearshore aquifer and subsequently greater transformation of land-derived nutrients. Nutrient processing was strongly controlled by the availability and reactivity of marine dissolved organic matter (DOM) as its degradation consumed O2, released inorganic N and P, and altered redox conditions in the salt-freshwater mixing zones. For the conditions and reaction network simulated, nutrient regeneration by marine DOM degradation was independent of the seawater-freshwater mixing intensity, and therefore was greatest for the wave case due to the high seawater influx. For simulations without marine DOM considered, NO3- discharge to the sea increased by 32% for the tidal case (A = 0.5 m) compared to only 13% and 8% for the wave (Hrms = 1 m) and no oceanic forcing cases. With labile marine DOM considered, the NO3- discharge decreased by 90% relative to the land-derived flux for the tidal case (A = 0.5 m). For all simulations PO43- removal was high due to its adsorption to Fe oxide minerals. The model enables evaluation of the complex coupled physical-biogeochemical processes controlling nutrient loading to the sea via submarine groundwater discharge in dynamic coastal environments.

  3. Near-shore hypoxia in the Chesapeake Bay: Patterns and relationships among physical factors

    1990-06-01

    Near-shore, shallow waters in the Chesapeake Bay periodically experience episodes of anoxia or severe hypoxia during summer. In order to examine the severity and temporal pattern of hypoxia, and environmental factors that may lead to such episodes, dissolved oxygen, salinity and temperature were measured at 15-min intervals during the summers of 1987 and 1988 in a western shore oyster bed. Bottom dissolved oxygen concentrations averaged lower at a 4-m site than at a 2-m site. At the 4-m site, dissolved oxygen concentrations dropped below 2 mg l -1 during approximately 40% of days and below 1 mg l -1 during approximately 10% of days each summer. However, diel fluctuations in oxygen concentrations were sufficiently large that even on days of the most severe oxygen minima, dissolved oxygen concentrations always reached or exceeded a level tolerable by most estuarine organisms during some part of the day. During episodes of severe hypoxia on the western shore of the Chesapeake Bay, oxygen minima (1) coincided with increased salinities and ebb tides, (2) were preceded by winds from the S-SSE (minima of ?0·5 1 mg l -1) or SW (minima of 0·6-1·1 mg l -1), and (3) were reached during 22.00-06.00 hours. Severe hypoxia at the study site therefore appeared to result from intrusions of bottom water, which were most effectively driven by southerly winds. Tidal currents were required to provide the final force that brought deep water close to shore. The diel pattern of intrusions is most likely caused by winds, which were often either too strong or had too weak a southerly component to permit intrusions (without near-shore mixing and reaeration) to occur during afternoon-early evening hours, and the diel periodicity of tides. Short-term fluctuations in temperature and salinity were not as great as fluctuations in dissolved oxygen when compared to seasonal fluctuations of each parameter. For many organisms, short-term fluctuations in temperature and salinity may therefore be less likely to influence the habitability of areas such as the near-shore Chesapeake Bay than are similar duration fluctuations in dissolved oxygen concentrations.

  4. Southwest Washington littoral drift restoration—Beach and nearshore morphological monitoring

    A morphological monitoring program has documented the placement and initial dispersal of beach nourishment material (280,000 m3) placed between the Mouth of the Columbia River (MCR) North Jetty and North Head, at the southern end of the Long Beach Peninsula in southwestern Washington State. A total of 21 topographic surveys and 8 nearshore bathymetric surveys were performed between July 11, 2010, and November 4, 2011. During placement, southerly alongshore transport resulted in movement of nourishment material to the south towards the MCR North Jetty. Moderate wave conditions (significant wave height around 4 m) following the completion of the nourishment resulted in cross-shore sediment transport, with most of the nourishment material transported into the nearshore bars. The nourishment acted as a buffer to the more severe erosion, including dune overtopping and retreat, that was observed at the northern end of the study area throughout the winter. One year after placement of the nourishment, onshore transport and beach recovery were most pronounced within the permit area and to the south toward the MCR North Jetty. This suggests that there is some long-term benefit of the nourishment for reducing erosion rates locally, although the enhanced recovery also could be due to natural gradients in alongshore transport causing net movement of the sediment from north to south. Measurements made during the morphological monitoring program documented the seasonal movement and decay of nearshore sand bars. Low-energy conditions in late summer resulted in onshore bar migration early in the monitoring program. Moderate wave conditions in the autumn resulted in offshore movement of the middle bar and continued onshore migration of the outer bar. High-energy wave conditions early in the winter resulted in strong cross-shore transport and creation of a 3-bar system along portions of the coast. More southerly wave events occurred later in the winter and early spring and coincided with the complete loss of the outer bar and net loss of sediment from the study area. These data suggest that bar decay may be an important mechanism for exporting sediment from Benson Beach north to the Long Beach Peninsula. The measurements presented in this report represent one component of a broader monitoring program designed to track the movement of nourishment material on the beach and shoreface at this location, including continuous video monitoring (Argus), in situu measurements of hydrodynamics, and a physical tracer experiment. Field data from the monitoring program will be used to test numerical models of hydrodynamics and sediment transport and to improve the capability of numerical models to support regional sediment management.

  5. A Quick Response Forecasting Model of Pathogen Transport and Inactivation in Near-shore Regions

    Modeling methods supporting water quality assessments play a critical role by facilitating people to understand and promptly predict the potential threat of waterborne bacterial pathogens pose to human health. A mathematical model to describe and predict bacterial levels can provide foundation for water managers in making decisions on whether a water system is safe to open to the public. The inactivation (decay or die-off) rate of bacteria is critical in a bacterial model by controlling bacterial concentration in waters and depends on numerous factors of hydrodynamics, meteorology, geology, chemistry and biology. Transport and fate of waterborne pathogens in fresh water systems is an essentially three-dimensional problem, which requires a coupling of hydrodynamic equations and transport equations that describe the pathogen and suspended sediment dynamics. However, such an approach could be very demanding and time consuming from a practical point of view due to excess computational efforts. Long computation time may lead people unintentionally drinking or swimming in the contaminated water during the period before the predictive results of water quality come out. Therefore, it is very necessary to find a quick-response model to forecast bacterial concentration instantly to protect human health without any delay. Nearshore regions are the most commonly and directly used area for people in a huge water system. The prior multi-dimensional investigations of E. Coli and Enterococci inactivation in literature indicate that along-shore current predominated the nearshore region. Consequently, the complex dynamic conditions may be potentially simplified to one-dimensional scenario. In this research, a one-dimensional model system coupling both hydrodynamic and bacterial transport modules is constructed considering different complex processes to simulate the transport and fate of pathogens in nearshore regions. The quick-response model mainly focuses on promptly forecasting purpose and will be verified and calibrated with the available data collected from southern Lake Michigan. The modeling results will be compared with those from prior multi-dimensional models. This model is specifically effective for the outfall-controlled waters, where pathogens are primarily predominated by loadings from nearby tributaries and tend to show wide variations in concentrations.

    Wildfire is a common disturbance that can significantly alter vegetation in watersheds and affect the rate of sediment and nutrient transport to adjacent nearshore oceanic environments. Changes in runoff resulting from heterogeneous wildfire effects are not well-understood due to both limitations in the field measurement of runoff and temporally-limited spatial data available to parameterize runoff models. We apply replicable, scalable methods for modeling wildfire impacts on sediment and nonpoint source pollutant export into the nearshore environment, and assess relationships between wildfire severity and runoff. Nonpoint source pollutants were modeled using a GIS-based empirical deterministic model parameterized with multi-year land cover data to quantify fire-induced increases in transport to the nearshore environment. Results indicate post-fire concentration increases in phosphorus by 161 percent, sediments by 350 percent and total suspended solids (TSS) by 53 percent above pre-fire years. Higher wildfire severity was associated with the greater increase in exports of pollutants and sediment to the nearshore environment, primarily resulting from the conversion of forest and shrubland to grassland. This suggests that increasing wildfire severity with climate change will increase potential negative impacts to adjacent marine ecosystems. The approach used is replicable and can be utilized to assess the effects of other types of land cover change at landscape scales. It also provides a planning and prioritization framework for management activities associated with wildfire, including suppression, thinning, and post-fire rehabilitation, allowing for quantification of potential negative impacts to the nearshore environment in coastal basins.

    Acquisition of high resolution time series of water column and bottom dissolved oxygen (DO) concentrations inform the dynamics of oxygen depletion in St Helena Bay in the southern Benguela upwelling system at several scales of variability. The bay is characterized by seasonally recurrent hypoxia (<1.42 ml l-1) associated with a deep pool of oxygen-depleted water and episodic anoxia (<0.02 ml l-1) driven by the nearshore (<20 m isobath) decay of red tide. Coastal wind forcing influences DO concentrations in the nearshore through its influence on bay productivity and the development of red tides; through shoreward advection of the bottom pool of oxygen-depleted water as determined by the upwelling-downwelling cycle; and through its control of water column stratification and mixing. A seasonal decline in bottom DO concentrations of ˜1.2 ml l-1 occurs with a concurrent expansion of the bottom pool of oxygen depleted water in St Helena Bay. Upwelling of this water into the nearshore causes severe drops in DO concentration (<0.2 ml l-1), particularly during end-of-season upwelling, resulting in a significant narrowing of the habitable zone. Episodic anoxia through the entire water column is caused by localized degradation of red tides within the confines of the shallow nearshore environment. Oxygenation of the nearshore is achieved by ventilation of the water column particularly with the onset of winter mixing. No notable changes are evident in comparing recent measures of bottom DO concentrations in St Helena Bay to data collected in the late 1950s and early 1960s.

    The author has identified the following significant results. Winter and spring near-shore ice conditions were analyzed for the Beaufort Sea 1973-77, and the Chukchi Sea 1973-76. LANDSAT imagery was utilized to map major ice features related to regional ice morphology. Significant features from individual LANDSAT image maps were combined to yield regional maps of major ice ridge systems for each year of study and maps of flaw lead systems for representative seasons during each year. These regional maps were, in turn, used to prepare seasonal ice morphology maps. These maps showed, in terms of a zonal analysis, regions of statistically uniform ice behavior. The behavioral characteristics of each zone were described in terms of coastal processes and bathymetric configuration.

  11. Southwest Washington Littoral Drift Restoration Project: Beach and Nearshore Morphological Monitoring

    Shoreline change along the southwest Washington and northwest Oregon coast responds to both natural and anthropogenic drivers at a range of temporal and spatial scales. Within the last century, human interventions, primarily the construction of large jetties at the entrance to the Columbia River, have been the dominant driver of nearshore morphology and shoreline change in this area. These jetties caused the inlet to narrow and deepen, the ebb-tidal delta to migrate offshore into deeper water, and adjacent shorelines to first accrete then erode over distances of tens of kilometers and time scales of decades. Shoreline change modeling suggests that reduced local sediment supply owing to these morphological changes is causing a deficit of sand feeding the shoreline, especially in the region of Benson Beach, just north of the mouth of the Columbia River. One of the goals of the Southwest Washington Littoral Drift Restoration (SW LDR) project is to assess the long-term viability of placing dredged material from the mouth of the Columbia River (MCR) directly on Benson Beach to supplement the littoral sediment budget. The SW LDR will be one of the largest beach nourishment projects in the Pacific Northwest, with approximately 200,000 - 400,000 m3 of dredged material being placed on Benson Beach during the summer of 2010. Extensive monitoring and modeling efforts are underway to evaluate the effectiveness of the project and to develop morphodynamic modeling tools to inform future Regional Sediment Management decisions. Overall project components include Argus beach monitoring, measurements of nearshore waves and currents, deployment of a sand tracer, morphodynamic modeling, and a morphological monitoring program. The primary purpose of the morphological monitoring program, and the focus for this presentation, is to track the response of beach and nearshore areas during and after the sand placement. Bathymetric data, collected using Personal Watercraft (PWCs) equipped with Real-time Kinematic (RTK) GPS and single-beam sonar systems, are merged with topographic measurements made with RTK GPS mounted on backpacks and on an all-terrain vehicle. A baseline survey was performed on July 11-12, 2010 to characterize beach and nearshore morphology prior to sand placement that began on July 31, 2010. The baseline survey reveals a large outer sand bar (~ 2 m amplitude) at -5 m depth, numerous shallow sand bars and swash bars, and a broad low-sloping dissipative beach. Two subsequent surveys, collected August 10th and 25th have begun to detect both background change (onshore migration of the outer bar) and movement of the placed sand. The majority of observed changes occur on the beach and in shallow areas (> -5 m), with no significant changes offshore of the outer bar. Initial analysis suggests southerly longshore transport of the nourishment sand driven by waves predominantly from the NW during the first phase of the monitoring. Additional surveys in the fall will continue to monitor the fate of the nourishment and help to assess whether anticipated changes in wave direction and magnitude force sediment offshore and northward as expected.

  12. The Performance of Nearshore Dredge Disposal at Ocean Beach, San Francisco, California, 2005-2007

    Ocean Beach, California, contains an erosion hot spot in the shadow of the San Francisco ebb tidal delta that threatens valuable public infrastructure as well as the safe recreational use of the beach. In an effort to reduce the erosion at this location a new plan for the management of sediment dredged annually from the main shipping channel at the mouth of San Francisco Bay was implemented in May 2005 by the United States Army Corps of Engineers, San Francisco District (USACE). The USACE designated a temporary nearshore dredge disposal site for the annual disposal of about 230,000 m3 (300,000 yd3) of sand about 750 m offshore and slightly south of the erosion hot spot, in depths between approximately 9 and 14 m. The site has now been used three times for a total sediment disposal of about 690,000 m3 (about 900,000 yds3). The disposal site was chosen because it is in a location where strong tidal currents and open-ocean waves can potentially feed sediment toward the littoral zone in the reach of the beach that is experiencing critical erosion, as well as prevent further scour on an exposed outfall pipe. The onshore migration of sediment from the target disposal location might feed the primary longshore bar or the nearshore zone, and provide a buffer to erosion that peaks during winter months when large waves impact the region. The United States Geological Survey (USGS) has been monitoring and modeling the bathymetric evolution of the test dredge disposal site and the adjacent coastal region since inception in May 2005. This paper reports on the first 2.5 years of this monitoring program effort (May 2005 to December 2007) and assesses the short-term coastal response. Here are the key findings of this report: *Approximately half of the sediment that has been placed in the nearshore dredge-disposal site during the 2.5 years of this study remains within the dredge focus area. *In the winter of 2006-7, large waves transported the dredge-mound material onshore. *High rates of seasonal cross-shore sediment transport mask any potential profile change in the Coastal Profiling System data due to dredge placement. *Pockets of accretion have been recorded by topographic surveying adjacent to the dredge site, but it is unclear if the accretion is linked to the nourishment. *Cross-shore profile modeling suggests that dredge material must be placed in water depths no greater than 5 m to drive a positive shoreline response. *Area modeling demonstrates that the new dredge site increases wave dissipation and modifies local sediment-transport patterns, although the effect on the nearshore morphology is largely negligible. *Any increase in beach width or wave energy-dissipation related to the nourishment is likely to be realized only in the vicinity directly onshore of the nourishment site, which is several hundred meters south of the area of critical erosion. *Larger waves from the northwest and smaller waves from the west or southwest contribute most to the sediment transport from the dredge mound onshore.

    The author has identified the following significant results. On the basis of analysis of late winter 1973, 1974, and 1975 LANDSAT imagery of the Beaufort Sea coast of Alaska, the following conclusions regarding near-shore ice conditions were made: (1) by March, the seaward limit of contiguous ice is often beyond the 10 fathom contour. (2) During March, shearing can and does take place along a line roughly coincident with the 10 fathom contour. (3) Ice motions during these shearing events are not extremely great, generally on the order of 10 km. (4) Many large ice features have already been formed by late February. (5) Based on look-ahead at later LANDSAT imagery, it seems apparent that Beaufort Seas shore-fast ice was already formed by late February and may well be safe for exploratory activities from this data forward until the melt season.

  14. Coral bleaching: one disturbance too many for near-shore reefs of the Great Barrier Reef

    2010-09-01

    The dynamic nature of coral communities can make it difficult to judge whether a reef system is resilient to the current disturbance regime. To address this question of resilience for near-shore coral communities of the Great Barrier Reef (Australia) a data set consisting of 350 annual observations of benthic community change was compiled from existing monitoring data. These data spanned the period 1985-2007 and were derived from coral reefs within 20 km of the coast. During years without major disturbance events, cover increase of the Acroporidae was much faster than it was for other coral families; a median of 11% per annum compared to medians of less than 4% for other coral families. Conversely, Acroporidae were more severely affected by cyclones and bleaching events than most other families. A simulation model parameterised with these observations indicated that while recovery rates of hard corals were sufficient to compensate for impacts associated with cyclones and crown-of-thorns starfish, the advent of mass bleaching has lead to a significant change in the composition of the community and a rapid decline in hard coral cover. Furthermore, if bleaching events continue to occur with the same frequency and severity as in the recent past, the model predicts that the cover of Acroporidae will continue to decline. Although significant cover of live coral remains on near-shore reefs, and recovery is observed during inter-disturbance periods, it appears that this system will not be resilient to the recent disturbance regime over the long term. Conservation strategies for coral reefs should focus on both mitigating local factors that act synergistically to increase the susceptibility of Acroporidae to climate change while promoting initiatives that maximise the recovery potential from inevitable disturbances.

  15. Neutrophilic Iron-Oxidizing “Zetaproteobacteria” and Mild Steel Corrosion in Nearshore Marine Environments ? †

    2011-01-01

    Microbiologically influenced corrosion (MIC) of mild steel in seawater is an expensive and enduring problem. Little attention has been paid to the role of neutrophilic, lithotrophic, iron-oxidizing bacteria (FeOB) in MIC. The goal of this study was to determine if marine FeOB related to Mariprofundus are involved in this process. To examine this, field incubations and laboratory microcosm experiments were conducted. Mild steel samples incubated in nearshore environments were colonized by marine FeOB, as evidenced by the presence of helical iron-encrusted stalks diagnostic of the FeOB Mariprofundus ferrooxydans, a member of the candidate class “Zetaproteobacteria.” Furthermore, Mariprofundus-like cells were enriched from MIC biofilms. The presence of Zetaproteobacteria was confirmed using a Zetaproteobacteria-specific small-subunit (SSU) rRNA gene primer set to amplify sequences related to M. ferrooxydans from both enrichments and in situ samples of MIC biofilms. Temporal in situ incubation studies showed a qualitative increase in stalk distribution on mild steel, suggesting progressive colonization by stalk-forming FeOB. We also isolated a novel FeOB, designated Mariprofundus sp. strain GSB2, from an iron oxide mat in a salt marsh. Strain GSB2 enhanced uniform corrosion from mild steel in laboratory microcosm experiments conducted over 4 days. Iron concentrations (including precipitates) in the medium were used as a measure of corrosion. The corrosion in biotic samples (7.4 ± 0.1 mM) was significantly higher than that in abiotic controls (5.0 ± 0.1 mM). These results have important implications for the role of FeOB in corrosion of steel in nearshore and estuarine environments.

    Nearshore patterns of ice motion near Barrow, Alaska, were monitored between 1973 and 1979 with a sea ice radar system. Side scan sonar surveys of the seafloor were made at the same location during the summers of 1977 and 1978. The two data sets provide information on ice motion, ice gouging, and the rate and character of seabed deformation by ice. Four ice stages (open water, freeze-up, winter, and breakup) can be defined on the basis of the frequency and patterns of ice motion and ice cover processes as recorded by the radar system. In all four ice stages the dominant ice motion was nearly parallel to the coast. Side scan sonar surveys show that the principal ice gouge directions nearshore were at a high angle to the coast and to the predominant direction of ice drift in both years. Gouge density was greatest in a narrow zone centered about the 10-m isobath which reflects the distribution of deep ice keels and the pattern of reworking of the seafloor by waves and currents. We believe the majority of observed gouges were formed by keels of multiyear ice floes during an event that occurred in July 1975, 2 years before the first seabed survey. Persistence of the gouge pattern from 1975 until 1977 is attributed to persistence of the ice cover and limited reworking by waves and currents, or additional gouging. The observed decrease in gouge density between 1977 and 1978 is attributed to (1) seafloor reworking and gouge infilling by storms and (2) the absence of ice conditions that were conducive to creating fresh gouges.

    The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. To better understand present temperature regimes, we assembled a 29-year nearshore time series of mean monthly SSTs along the North Pacific coastline using remotely-sensed satellite data collected with the Advanced Very High Resolution Radiometer (AVHRR) instrument. We then used the dataset to describe nearshore (&20 km offshore) SST patterns of 16 North Pacific ecoregions delineated by the Marine Ecoregions of the World (MEOW) hierarchical schema. Annual mean temperature varied from 3.8??C along the Kamchatka ecoregion to 24.8??C in the Cortezian ecoregion. There are smaller annual ranges and less variability in SST in the Northeast Pacific relative to the Northwest Pacific. Within the 16 ecoregions, 31-94% of the variance in SST is explained by the annual cycle, with the annual cycle explaining the least variation in the Northern California ecoregion and the most variation in the Yellow Sea ecoregion. Clustering on mean monthly SSTs of each ecoregion showed a clear break between the ecoregions within the Warm and Cold Temperate provinces of the MEOW schema, though several of the ecoregions contained within the provinces did not show a significant difference in mean seasonal temperature patterns. Comparison of these temperature patterns shared some similarities and differences with previous biogeographic classifications and the Large Marine Ecosystems (LMEs). Finally, we provide a web link to the processed data for use by other researchers.

    2009-01-01

    Nest site selection is a critical component of reproduction and has presumably evolved in relation to predation, local resources, and microclimate. We investigated nest-site choice by king eiders (Somateria spectabilis) on the coastal plain of northern Alaska, USA, 2003-2005. We hypothesized that nest-site selection is driven by predator avoidance and that a variety of strategies including concealment, seclusion, and conspecific or inter-specific nest defense might lead to improved nesting success. We systematically searched wetland basins for king eider nests and measured habitat and social variables at nests (n = 212) and random locations (n = 493). King eiders made use of both secluded and concealed breeding strategies; logistic regression models revealed that females selected nests close to water, on islands, and in areas with high willow (Salix spp.) cover but did not select sites near conspecific or glaucous gull (Larus hyperboreus) nests. The most effective nest-placement strategy may vary depending on density and types of nest predators; seclusion is likely a mammalian-predator avoidance tactic whereas concealment may provide protection from avian predators. We recommend that managers in northern Alaska attempt to maintain wetland basins with islands and complex shorelines to provide potential nest sites in the vicinity of water. ??

  15. Are Regional Operational Wind-Waves Models Usable to Predict Coastal and Nearshore Wave Climate?

    NASA Astrophysics Data System (ADS)

    Lambert, A. P.; Neumeier, U.; Jacob, D.; Savard, J.

    2012-12-01

    Estuary and Gulf of Saint-Lawrence (EGSL) shores are subjected to strong erosion linked to storminess. Due to the likely presence of sea ice and to the high tidal range affecting the north shores of the EGSL, it is impossible to measure wave parameters at depth lesser than 10m from November to April, i.e. the storm period. Winter waves can be forecasted by the operational Regional Deterministic Wave Prediction System (RDWPS) from the Canadian Meteorological Center (CMC). However, spatial resolution of the RDWPS in the EGSL is 0.04°x0.06° (5x5km @ 49°N), which theoretically limits its application to areas of low bathymetric gradients and does neither destined it to the prediction of coastal nor nearshore waves. Nevertheless, given the lack of nearshore wave measurements during the late fall and winter period, it might seem wise to use the RDWPS data for operational purposes of warning and coastal structure design. This research thus evaluates the performance of the RDWPS for this period, both in the coastal and nearshore areas of a complex bathymetric domain. Our method is based on: 1. A direct comparison of RDWPS wave parameters time series to those produced from two instruments berthed in front of Sept-Iles, North Shore, Quebec (50° 10.3' N 66° 13.5' W). M1 mooring is deployed permanently throughout the year at -32m MSL, while M2 is deployed from April to November at -8m MSL. These comparisons are made from 01/10/2010 to 31/12/2011 (winter period). 2. A high-resolution (0.2x0.2km) coastal wind-wave model (SWAN v.40.85) is locally nested in the EGSL RDWPS domain in order to propagate waves from quasi-infinite depth to the shore at the site location, including moorings positions. Our implementation uses the same source terms, physics and inputs as in the RDWPS implementation of WAM. This allows producing reference time series for the winter at the M2 location. RDWPS data are thus also compared with these model outputs for the same period as 1. Our results show that the RDWPS predicted the wave parameters with a very good sensitivity, but with a strong linear overestimation of Hm02 (+45% ± 10%) and Tm0 (+45% ± 30%) at M1 location. A first implementation of SWAN (SI1) using the RDWPS wave data as boundary conditions shows that 55% of this overestimation at M1 is related to the bathymetric grid's coarse resolution. A second implementation of SWAN (SI2) with a linear reduction of 20% of the RDWPS Hm02 boundary condition and using the 10m wind components rather than the 40m as in the RDWPS shows a very good agreement with M1 measured values, demonstrating that remaining overestimation is linked to winds too strong. The comparison of SWAN SI2 results at M2 position vs. M2 measured data shows a very good fit, without overestimation. The comparison for the winter period of SWAN SI2 results at M2 position vs. RDWPS data at the three closest grid points shows that Hm02 can be reasonably assessed at this depth for operational purposes taking into account a linear reduction factor, estimated 0.6 for our site.

    Nearshore upwelling due to predictable large internal bores may be a widespread phenomenon along the west coast of North America. Internal tidal bores (breaking internal tidal waves) cause drops in surface water temperature that last for 2–9 days. Negative surface water temperature anomalies (anomaly = daily datum minus day-of-the-year average) often reflect large internal tidal bores. These anomalies are predictable

    In order to gain insight into the formation dynamics of mudbanks off the Kerala coast of India, extensive surveying of the nearshore bathymetry along with sediment characterization was undertaken. The textural and geotechnical properties of the surficial sediments of a mudbank were determined during pre-monsoon, monsoon, and post-monsoon periods. The mudbank sediments were clayey silts with high water and organic carbon contents, high Atterberg limits, and low bulk density, and therefore very susceptible to entrainment. During the monsoon, the mudbank regime was characterised by enhanced turbidity and a benthic fluff layer, triggered by the increasing swell of the early monsoon period. Re-suspension exposed a more consolidated, previously sub-bottom, layer which exhibited lower water content and greater shear strength than the pre-monsoon seabed. Texturally, the monsoon seabed was similar to the pre-monsoon seabed, with the same modal grain size, but the proportions of sand and coarse silt increased nearshore, while the proportions of fine and very fine silt increased offshore. There was a seaward-fining textural gradient at all times, but this became pronounced during the monsoon period. Paradoxically, the monsoonal seabed displayed greatly reduced wet bulk density. It is hypothesized that this was due to the presence of gas, probably methane, in the sediments (while the pre-monsoon sediments were fully saturated, the monsoon sediments were only 83% saturated). We speculate that the gas was forced into the surficial sediments either by wave pumping (at the onset of the monsoon) or by seaward-flowing subbottom freshwater (derived from monsoonal rains). With the waning of the monsoon, the benthic fluid mud layer rapidly disappeared and the seabed returned to its pre-monsoon state as suspended sediments were redeposited. The mudbank regime is therefore essentially an in situ phenomenon. It is suggested that the mudbanks are palimpsest, marshy, lagoonal deposits, rich in organic matter and derived gas, that were submerged after a marine transgression. The surficial sediment is annually entrained during the monsoon, but erosion is limited by the formation of the benthic fluid mud layer, which attenuates wave generated turbulence. Although some fine sediment disperses alongshore and offshore, most is returned to the seabed as the monsoon declines.

  1. Wind-induced nearshore sediment resuspension in a lake during a winter storm

    Sediment resuspension is the process by which sediment is entrained into the water column at the sediment-water interface. It occurs when the bottom shear stress exceeds the critical shear stress and has the potential to negatively impact water quality. Wind-induced sediment resuspension could be a factor contributing to the declining clarity of the nearshore at Lake Tahoe, California-Nevada and is therefore the subject of this study. An observational experiment included vertical profiles of water temperature using a thermistor chain; vertical profiles of water currents as well as surface wave periods and significant wave heights using a Nortek AWAC; high-frequency, near-bed measurements of water velocity using a Nortek Vector and a Sontek ADVOcean Probe; and suspended sediment concentrations using a LISST-100X. During a winter storm event we observed simultaneous peaks in wind speed, significant wave height and wave period, and suspended sediment concentration. Coincident peaks in suspended sediment concentration and wind speed strongly suggested wind-driven resuspension. During this same stormy period currents shifted to align with the wind. Total bottom shear stress was computed from the high-frequency, near-bed velocity data. During this winter storm, measured estimates of total bottom shear stress exceeded the critical shear stress for incipient motion corresponding to an average grain size of 400 ?m. Bottom shear stress was also partitioned according to its provenance (wind-waves; mean currents; and random motions). We implemented the wind-wave model STWAVE to simulate nearshore wind-wave growth and propagation, from which we derived the bottom orbital velocity to estimate bottom shear stress due to wind-waves. When wind directions favored a larger fetch, promoting full development of the wave field, the simulated bottom shear stress from STWAVE was in good agreement with the measured bottom shear stress attributed to wind-waves. We estimated bottom shear stress due to currents as a percentage of the total wind-induced shear stress at the surface of the lake, which was in turn derived from the wind record and the quadratic drag law. Simulated and measured bottom shear stress attributed to mean currents were in good agreement and remained small, which was to be expected. The wind-waves contributed far more to the development of the bottom shear stress during critical periods. For those times when the total bottom shear stress was in excess of the critical shear stress, the sediment entrainment rates were well represented by the 1991 Garcia and Parker formula.

    Great Lakes coastal wetlands provide a critical habitat for many fish species throughout their life cycles. Once home to one of the largest wetland complexes in the Great Lakes, coastal wetlands in the Huron–Erie Corridor (HEC) have decreased dramatically since the early 1900s. We characterized the nearshore fish communities at three different wetland complexes in the HEC using electrofishing, seines, and fyke nets. Species richness was highest in the Detroit River (63), followed by the St. Clair Delta (56), and Western Lake Erie (47). The nearshore fish communities in the Detroit River and St. Clair Delta consisted primarily of shiners, bluntnose minnow, centrarchids, and brook silverside, while the Western Lake Erie sites consisted of high proportions of non-native taxa including common carp, gizzard shad, goldfish, and white perch. Species richness estimates using individual-based rarefaction curves were higher when using electrofishing data compared to fyke nets or seine hauls at each wetland. Twelve fish species were captured exclusively during electrofishing assessments, while one species was captured exclusively in fyke nets, and none exclusively during seine hauls. Western Lake Erie wetlands were more indicative of degraded systems with lower species richness, lower proportion of turbidity intolerant species, and increased abundance of non-native taxa. This work highlights the importance of coastal wetlands in the HEC by capturing 69 different fish species utilizing these wetlands to fulfill life history requirements and provides insight when selecting gears to sample nearshore littoral areas.

    Doppler spectral signatures of sea echoes from two-dimensional (2-D) fetch- and depth-limited sea surfaces are investigated using the second-order small-slope approximation (SSA-II) model. For the description of 2-D nearshore sea surface, the revised choppy wave model (RCWM) is applied, which takes into account the wind fetch effect and water depth effect in nearshore marine environment. Comparisons of computed results in co-polarizations and cross polarization at various incident angles show that Doppler shift and spectral bandwidth can be greatly influenced by hydrodynamic modulation of waves in the large wind fetch and small water depth marine environment, which indicates that the hydrodynamic modulation induced by shoaling effect would be greatly enhanced in the situation of the nearshore shallow sea with a long wind fetch. The differences in variation trend between results in co-polarizations and cross polarization also reflect varying degrees of influence of aforementioned hydrodynamic modulation on different scattering mechanisms.

    Geophysics seems full of monsters like Victor Hugo's Court of Miracles and monstrous extremes have been statistically considered as outliers with respect to more normal events. However, a characteristic magnitude separating abnormal events from normal ones would be at odd with the generic scaling behaviour of nonlinear systems, contrary to "fat tailed" probability distributions and self-organized criticality. More precisely, it can be shown [1] how the apparent monsters could be mere manifestations of a singular measure mishandled as a regular measure. Monstrous fluctuations are the rule, not outliers and they are more frequent than usually thought up to the point that (theoretical) statistical moments can easily be infinite. The empirical estimates of the latter are erratic and diverge with sample size. The corresponding physics is that intense small scale events cannot be smoothed out by upscaling. However, based on a few examples, it has also been argued [2] that one should consider "genuine" outliers of fat tailed distributions so monstrous that they can be called "dragon-kings". We critically analyse these arguments, e.g. finite sample size and statistical estimates of the largest events, multifractal phase transition vs. more classical phase transition. We emphasize the fact that dragon-kings are not needed in order that the largest events become predictable. This is rather reminiscent of the Feast of Fools picturesquely described by Victor Hugo.

    Seabirds are sensitive indicators of changes in marine ecosystems and might integrate and/or amplify the effects of climate forcing on lower levels in food chains. Current knowledge on the impact of climate changes on penguins is primarily based on Antarctic birds identified by using flipper bands. Although flipper bands have helped to answer many questions about penguin biology, they were shown in some penguin species to have a detrimental effect. Here, we present for a Subantarctic species, king penguin (Aptenodytes patagonicus), reliable results on the effect of climate on survival and breeding based on unbanded birds but instead marked by subcutaneous electronic tags. We show that warm events negatively affect both breeding success and adult survival of this seabird. However, the observed effect is complex because it affects penguins at several spatio/temporal levels. Breeding reveals an immediate response to forcing during warm phases of El Niño Southern Oscillation affecting food availability close to the colony. Conversely, adult survival decreases with a remote sea-surface temperature forcing (i.e., a 2-year lag warming taking place at the northern boundary of pack ice, their winter foraging place). We suggest that this time lag may be explained by the delay between the recruitment and abundance of their prey, adjusted to the particular 1-year breeding cycle of the king penguin. The derived population dynamic model suggests a 9% decline in adult survival for a 0.26 degrees C warming. Our findings suggest that king penguin populations are at heavy extinction risk under the current global warming predictions. PMID:18268328

    Seabirds are sensitive indicators of changes in marine ecosystems and might integrate and/or amplify the effects of climate forcing on lower levels in food chains. Current knowledge on the impact of climate changes on penguins is primarily based on Antarctic birds identified by using flipper bands. Although flipper bands have helped to answer many questions about penguin biology, they were shown in some penguin species to have a detrimental effect. Here, we present for a Subantarctic species, king penguin (Aptenodytes patagonicus), reliable results on the effect of climate on survival and breeding based on unbanded birds but instead marked by subcutaneous electronic tags. We show that warm events negatively affect both breeding success and adult survival of this seabird.

    Snohomish County in western Washington State began converting its vehicle fleet to use a blend of biodiesel and petroleum diesel in 2005. As prices for biodiesel rose due to increased demand for this cleaner-burning fuel, Snohomish County looked to its farmers to ���¢��������grow���¢������� this fuel locally. Suitable seed crops that can be crushed to extract oil for use as biodiesel feedstock include canola, mustard, and camelina. The residue, or mash, has high value as an animal feed. County farmers began with 52 acres of canola and mustard crops in 2006, increasing to 250 acres and 356 tons in 2008. In 2009, this number decreased to about 150 acres and 300 tons due to increased price for mustard seed.

  16. Assessment of the changes induced by a wave energy farm in the nearshore wave conditions

    Starting from the observation that an important next stage in exploiting the ocean energy is to install large arrays of several identical devices in order to raise their overall electricity production, the present work has as objective to assess the local and coastal impact of a large wave farm that would operate in the Portuguese coastal environment. The target area is the Portuguese maritime pilot zone, São Pedro de Moel, which is located in the central part of the Portuguese continental nearshore. A generic wave farm was considered and various transmission situations were analyzed. The study started with the situation without wave farm (zero absorption) and subsequently different scenarios were considered by gradually increasing the conditions to the hypothetic case of the total absorption. For each case study, model simulations were performed covering the entire year 2009 using a wave prediction system based on Wave Watch 3, for the wave generation at the level of the entire North Atlantic Ocean, and on SWAN, for the coastal wave transformation. In this way, a comprehensive picture of the possible impact of the wave farm is provided. The results show that the presence of a wave farm operating offshore has a strong influence on the wave conditions immediately down wave. Although this influence is usually attenuated at the level of the coastline, it appears as obvious a general decrease in terms of significant wave height due to the wave farm, but also some other wave parameters are modified.

  17. Mapping of Submerged Aquatic Vegetation Using Autonomous Underwater Vehicles in Nearshore Regions

    2007-10-02

    The use of an autonomous underwater vehicle (AUV) equipped with sidescan sonar was investigated for determining the boundaries of nearshore submerged aquatic vegetation beds, specifically eelgrass (Zostera marina). Shifts in eelgrass bed morphology, size, and distribution are used as indicators in monitoring programs to measure the impacts of coastal development and environmental stressors on eelgrass and to establish the efficacy of restoration programs. However, many monitoring programs necessarily extend over multiple-year time periods. Therefore, techniques that are easily reproducible, accurate, and cost-effective can demonstrate distinct advantages over some of the more traditional and labor-intensive methods, such as diver assessments and transects of shoot counts. Remote monitoring of eelgrass beds using satellite and aerial imagery has been demonstrated with moderate success, but requires groundtruthing, which can be costly and which frequently cannot delineate the deeper boundaries of eelgrass beds. One possible means for low-cost mapping is the use of AUVs equipped with acoustic imaging hardware. AUVs provide an ideal platform, because they can be deployed by small teams (two people), they are highly maneuverable, they can cover large areas over a relatively short time period (3knot operational speed), and they are equipped with multiple oceanographic instruments for correlated data collection. This paper describes the use of sidescan-equipped AUV technology deployed over multiple time periods at the same location where imagery of eelgrass beds was obtained and analyzed for comparative purposes.

    Viruses, most of which are phage, are extremely abundant in marine sediments, yet almost nothing is known about their identity or diversity. We present the metagenomic analysis of an uncultured near-shore marine-sediment viral community. Three-quarters of the sequences in the sample were not related to anything previously reported. Among the sequences that could be identified, the majority belonged to double-stranded DNA phage. Temperate phage were more common than lytic phage, suggesting that lysogeny may be an important lifestyle for sediment viruses. Comparisons between the sediment sample and previously sequenced seawater viral communities showed that certain phage phylogenetic groups were abundant in all marine viral communities, while other phage groups were under-represented or absent. This 'marineness' suggests that marine phage are derived from a common set of ancestors. Several independent mathematical models, based on the distribution of overlapping shotgun sequence fragments from the library, were used to show that the diversity of the viral community was extremely high, with at least 10(4) viral genotypes per kilogram of sediment and a Shannon index greater than 9 nats. Based on these observations we propose that marine-sediment viral communities are one of the largest unexplored reservoirs of sequence space on the planet. PMID:15156913

    2007-01-01

    A mode-splitting method is applied to the quasi-3D nearshore circulation equations in generalized curvilinear coordinates. The gravity wave mode and the vorticity wave mode of the equations are derived using the two-step projection method. Using an implicit algorithm for the gravity mode and an explicit algorithm for the vorticity mode, we combine the two modes to derive a mixed difference–differential equation with respect to surface elevation. McKee et al.'s [McKee, S., Wall, D.P., and Wilson, S.K., 1996. An alternating direction implicit scheme for parabolic equations with mixed derivative and convective terms. J. Comput. Phys., 126, 64–76.] ADI scheme is then used to solve the parabolic-type equation in dealing with the mixed derivative and convective terms from the curvilinear coordinate transformation. Good convergence rates are found in two typical cases which represent respectively the motions dominated by the gravity mode and the vorticity mode. Time step limitations imposed by the vorticity convective Courant number in vorticity-mode-dominant cases are discussed. Model efficiency and accuracy are verified in model application to tidal current simulations in San Francisco Bight.

    Numerical modeling of a beach nourishment project is conducted to enable a detailed evaluation of the processes associated with the effects of nearshore dredge pits on nourishment evolution and formation of erosion hot spots. A process-based numerical model, Delft3D, is used for this purpose. The analysis is based on the modification of existing bathymetry to simulate "what if" scenarios with/without the bathymetric features of interest. Borrow pits dredged about 30??years ago to provide sand for the nourishment project have a significant influence on project performance and formation of erosional hot spots. It was found that the main processes controlling beach response to these offshore bathymetric features were feedbacks between wave forces (roller force or alongshore component of the radiation stress), pressure gradients due to differentials in wave set-up/set-down and bed shear stress. Modeling results also indicated that backfilling of selected borrow sites showed a net positive effect within the beach fill limits and caused a reduction in the magnitude of hot spot erosion. ?? 2008 Elsevier B.V.

    Composite, nearshore, whole fish samples of selected species, collected in fall 1983 from 13 Lake Michigan tributaries and Grand Traverse Bay, were analyzed for a wide range of pesticides and priority pollutants using gas chromatography-mass spectrometry. This study was carried out to identify existing source areas for known and previously unrecognized toxic substances. The authors strategy was to analyze those resident fish with the highest likely levels of contaminant. All fish analyzed exceeded the 2 mg/kg FDA action levels for PCBs, while 50% of the samples exceeded the DDTr IJC objective of 1 mg/kg. St. Joseph River common carp (Cyprinus carpio) carried the heaviest contaminant burden of all fish examined for PCBs (27.6 mg/kg), DDTr (10.2 kg/mg), and toxaphene (3.3 mg/kg); chlordane levels (0.85 mg/kg) were second highest to those in Kalamazoo River common carp (0.87 mg/kg). Concentrations of PCBs, toxaphene, DDT, DDE, and other pesticides were higher in bottom-feeding fish, such as common carp, than in top predators, e.g., northern pike (Esox lucius). Bottom feeders are relatively fatty fish, and live and feed near contaminated sediments, which increases their potential to bioaccumulate fat-soluble contaminants. Pesticides were also present in elevated concentrations in fish from sites with higher industrial and agricultural development. 31 references, 1 figure, 4 tables.

    The nearshore distributions of postlarval brown shrimp Farfantepenaeus aztecus (Ives, 1891) were investigated at four approximately equidistant sites along a section of Galveston Island, Texas. Simultaneous, replicate plankton samples were collected along with environmental measurements at each site during three consecutive days each week for a period of four weeks during April 1992. The data were modelled using analysis of variance and stepwise regression to evaluate the spatial, temporal and environmental factors contributing to changes in density. Postlarval densities differed significantly among the four weeks during the study, however, day was not a significant model effect. Changes in weekly distributions appeared correlated to the presence of winds favourable for onshore transport of water. The distributions of postlarvae were highly variable along the Island with significantly greater densities at sites located on sections of open beach and significantly lower densities in the vicinity of shoreline stabilization structures (groins and jetties). Turbidity, water and air temperature, salinity, and dissolved oxygen were all significantly related to postlarval density as were several interactions among environmental factors and turbidity and site. The variability observed in the study was used to estimate levels of sampling intensity required to achieve different levels of precision. Based on the high spatial and temporal variability in postlarval densities observed in this study, and our sampling effort calculations, we suggest that some of the difficulty in predicting landings of adult shrimp based on postlarval abundances may be due to insufficient sampling effort to accurately assess postlarval densities.

    The nearshore benthic environment of Lake Michigan represents a dynamic and little studied habitat. To explore the biology and response of this community to beach nourishment, Ponar samples were taken at 1.5, 3, and 6 m depths at 10 transects along the southern shore of Lake Michigan before and after beach nourishment. Forty taxa were identified, and two of these, Chaetogaster diastrophus and Nematoda, made up over 81% of all organisms collected. Shallow sites (??? 3 m) were generally dominated by C. diastrophus and Nematoda, and these sites represent communities adapted to constant wave induced sediment disturbance. Deep (6 m) sites were generally dominated by Nematoda, but fair numbers of C. diastrophus, Amphichaeta leydigi, Paracladopelma spp., and other less abundant taxa were identified. Greater diversity at deeper sites may be related to the stability resulting from reduced wave disturbance. A notable decrease in mean invertebrate density (P < 0.01) from 2001 to 2002 downdrift from the site of beach nourishment suggests that sand placement affected invertebrate populations, although a more thorough understanding of this community's response to environmental variables is required to further support this conclusion.

  4. Mechanisms of nearshore retention and offshore export of mussel larvae over the Agulhas Bank

    Ecological connectivity is critical for population dynamics but in many benthic species it is complicated by a planktonic larval phase, whose dispersal remains poorly understood. Using a plankton pump, we examine the distribution of intertidal mussel larvae along three axes: alongshore, cross-shelf and by depth during a large scale (600 km) cruise over the Agulhas Bank off southern Africa in August/September 2010. As a general pattern, higher veliger abundances were found close to the coast. Our analyses of the nearshore flow, estimated from ADCP data and the vertical distribution of larvae, show that onshore larval retention may be mediated by active vertical swimming through the water column guided by light and wind-induced turbulence. A massive offshore export of larvae off St Francis Bay was, however, observed during an Agulhas Current meander which influenced inner shelf waters. We hypothesize that, by increasing and homogenizing flow, the Agulhas Current may erase the effects of larval vertical positioning on onshore retention and transport larvae offshore. Our study highlights the need to integrate the effects of complex, region-specific physical dynamics with the swimming behaviour of larvae in order to explain their spatial distribution, population connectivity and the consequences for population dynamics.

    2009-01-01

    A coupled waves-currents-bathymetric evolution model (DELFT-3D) is compared with field measurements to test hypotheses regarding the processes responsible for alongshore varying nearshore morphological changes at seasonal time scales. A 2001 field experiment, along the beaches adjacent to Grays Harbor, Washington, USA, captured the transition between the high-energy erosive conditions of winter and the low-energy beach-building conditions typical of summer. The experiment documented shoreline progradation on the order of 10-20 m and on average approximately 70 m of onshore sandbar migration during a four-month period. Significant alongshore variability was observed in the morphological response of the sandbar over a 4 km reach of coast with sandbar movement ranging from 20 m of offshore migration to over 175 m of onshore bar migration, the largest seasonal-scale onshore migration event observed in a natural setting. Both observations and model results suggest that, in the case investigated here, alongshore variations in initial bathymetry are primarily responsible for the observed alongshore variable morphological changes. Alongshore varying incident hydrodynamic forcing, occasionally significant in this region due to a tidal inlet and associated ebb-tidal delta, was relatively minor during the study period and appears to play an insignificant role in the observed alongshore variability in sandbar behavior at kilometer-scale. The role of fully three-dimensional cell circulation patterns in explaining the observed morphological variability also appears to be minor, at least in the case investigated here. ?? 2009 Elsevier B.V.

    We previously reported that the macrophytic green alga Cladophora harbors high densities (up to 106 colony-forming units/g dry weight) of the fecal indicator bacteria, Escherichia coli and enterococci, in shoreline waters of Lake Michigan. However, the population structure and genetic relatedness of Cladophora-borne indicator bacteria remain poorly understood. In this study, 835 E. coli isolates were collected from Cladophora tufts (mats) growing on rocks from a breakwater located within the Indiana Dunes National Lakeshore in northwest Indiana. The horizontal fluorophore enhanced rep-PCR (HFERP) DNA fingerprinting technique was used to determine the genetic relatedness of the isolates to each other and to those in a library of E. coli DNA fingerprints. While the E. coli isolates from Cladophora showed a high degree of genetic relatedness (???92% similarity), in most cases, however, the isolates were genetically distinct. The Shannon diversity index for the population was very high (5.39). Both spatial and temporal influences contributed to the genetic diversity. There was a strong association of isolate genotypes by location (79% and 80% for lake- and ditch-side samplings, respectively), and isolates collected from 2002 were distinctly different from those obtained in 2003. Cladophora-borne E. coli isolates represented a unique group, which was distinct from other E. coli isolates in the DNA fingerprint library tested. Taken together, these results indicate that E. coli strains associated with Cladophora may be a recurring source of indicator bacteria to the nearshore beach. ?? 2007 Elsevier Ltd.

    The BOREAS AFM-2 team used the University of Wyoming King Air aircraft during IFCs 1, 2, and 3 in 1994 to collected pass-by-pass fluxes (and many other statistics) for the large number of level (constant altitude), straight-line passes used in a variety of flight patterns over the SSA and NSA and areas along the transect between these study areas. The data described here form a second set, namely soundings that were incorporated into nearly every research flight by the King Air in 1994. These soundings generally went from near the surface to above the inversion layer. Most were flown immediately after takeoff or immediately after finishing the last flux pattern of that particular day's flights. The parameters that were measured include wind direction, wind speed, west wind component (u), south wind component (v), static pressure, air dry bulb temperature, potential temperature, dewpoint, temperature, water vapor mixing ratio, and CO2 concentration. Data on the aircraft's location, attitude, and altitude during data collection are also provided. These data are stored in tabular ASCH files. The data files are available on a CD-ROM (see document number 20010000884) or from the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).

    1985-01-01

    Following the report of ten cases of respiratory illness in processors of frozen king crab, we investigated the conditions of work and the pulmonary and immunologic status of the workers in three crab-processing and one fish-packing (control) plant. Pulmonary function was measured before and after work, and skin tests were performed in subgroups matched for age, sex, and duration of current employment. The antibody response to king crab antigens was examined in sera from the subgroups and another (unrelated) control group. Extracts of crab meat, shell, and processing dust were used for skin testing and precipitin detection. FEV1, FVC, and MEFR decreased during the day in two crab processors, and precipitins were evident in sera from nine, but findings were normal in the fish packers. Crab meat elicited the strongest response, with multiple precipitin bands in some cases. Control sera showed no reaction. There was correlation between serology, results of skin tests, and symptoms. It is concluded that the inhalation of aerosolized crab antigen(s) may cause respiratory symptoms and can cause immunologic effects similar to those caused by other occupational respiratory allergens. We recommend preplacement and periodic medical examination of workers in crab-processing plants, improved ventilation in processing areas, and programs to discourage smoking. PMID:3976663

    King cobra (Ophiophagus hannah) serum was found to possess antihemorrhagic activity against king cobra hemorrhagin. The activity was stronger than that in commercial king cobra antivenom. An antihemorrhagin has been purified by ion exchange chromatography, affinity chromatography and gel filtration with a 22-fold purification and an overall yield of 12% of the total antihemorrhagic activity contained in crude serum. The purified antihemorrhagin was homogeneous in disc-PAGE and SDS-PAGE. Its apparent molecular weight determined by SDS-PAGE was 120 kDa. The antihemorrhagin was also active against other hemorrhagic snake venoms obtained in Thailand and Japan such as Calloselasma rhodostoma, Trimeresurus albolabris, Trimeresurus macrops and Trimeresurus flavoviridis (Japanese Habu). It inhibited the proteolytic activity of king cobra venom. It is an acid- and thermolabile protein and does not form precipitin lines against king cobra venom. PMID:12875876

  11. Dynamic temporal patterns of nearshore seepage flux in a headwater Adirondack lake

    NASA Astrophysics Data System (ADS)

    Sebestyen, Stephen D.; Schneider, Rebecca L.

    2001-07-01

    Although seepage in lakes is known to vary as a function of precipitation and watershed characteristics, temporal patterns of seepage flux over daily and weekly time scales have not been extensively studied with a concentrated effort of direct measurement of seepage in nearshore areas. In this study, seepage was intensively measured with seepage meters over two summers and during snowmelt in Lower Sylvan Pond, a small lake in the Adirondack Mountains region of New York State, USA. A consistent pattern of slight discharge (never exceeding 105 mL m -2 h -1) was observed at three stations along a segment of the shoreline near the inlet stream. A distinct temporal pattern of seepage was observed at three stations along another portion of the shoreline. Seepage discharged (>400 mL m -2 h -1) for a portion of the summer in 1998 and then shifted to recharge (<-500 mL m -2 h -1) for the remainder of the summer. A similar temporal pattern was observed again in 1999 but the transition to recharge occurred earlier and higher rates of discharge (610 mL m -2 h -1) and recharge (-608 mL m -2 h -1) were recorded. Additionally, seepage at these three stations increased after large rainfall events and a pronounced episodic increase of seepage was measured during snowmelt. Distinct seepage patterns along portions of the shoreline show that seepage can vary considerably within seasons and suggests a need to consider changes of seepage over time periods of days to weeks as well as among seasons and years. This study demonstrates that the resolution of temporal seepage data can be important to the understanding of water fluxes to aquatic ecosystems.

  12. Exploring the nearshore marine wind profile from field measurements and numerical hindcast

    NASA Astrophysics Data System (ADS)

    2012-12-01

    Wind power is the predominant offshore renewable energy resource. In the last years, offshore wind farms have become a technically feasible source of electrical power. The economic feasibility of offshore wind farms depends on the quality of the offshore wind conditions compared to that of onshore sites. Installation and maintenance costs must be balanced with more hours and a higher quality of the available resources. European offshore wind development has revealed that the optimum offshore sites are those in which the distance from the coast is limited with high available resource. Due to the growth in the height of the turbines and the complexity of the coast, with interactions between inland wind/coastal orography and ocean winds, there is a need for field measurements and validation of numerical models to understand the marine wind profile near the coast. Moreover, recent studies have pointed out that the logarithmic law describing the vertical wind profile presents limitations. The aim of this work is to characterize the nearshore vertical wind profile in the medium atmosphere boundary layer. Instrumental observations analyzed in this work come from the Idermar project (www.Idermar.es). Three floating masts deployed at different locations on the Cantabrian coast provide wind measurements from a height of 20 to 90 meters. Wind speed and direction are measured as well as several meteorological variables at different heights of the profile. The shortest wind time series has over one year of data. A 20 year high-resolution atmospheric hindcast, using the WRF-ARW model and focusing on hourly offshore wind fields, is also analyzed. Two datasets have been evaluated: a European reanalysis with a ~15 Km spatial resolution, and a hybrid downscaling of wind fields with a spatial resolution of one nautical mile over the northern coast of Spain.. These numerical hindcasts have been validated based on field measurement data. Several parameterizations of the vertical wind profile are evaluated and, based on this work, a particular parameterization of the wind profile is proposed.

    2011-01-01

    Relationships of diversity, distribution and abundance of benthic decapods in intertidal and shallow subtidal waters to 10 m depth are explored based on data obtained using a standardized protocol of globally-distributed samples. Results indicate that decapod species richness overall is low within the nearshore, typically ranging from one to six taxa per site (mean?=?4.5). Regionally the Gulf of Alaska decapod crustacean community structure was distinguishable by depth, multivariate analysis indicating increasing change with depth, where assemblages of the high and mid tide, low tide and 1 m, and 5 and 10 m strata formed three distinct groups. Univariate analysis showed species richness increasing from the high intertidal zone to 1 m subtidally, with distinct depth preferences among the 23 species. A similar depth trend but with peak richness at 5 m was observed when all global data were combined. Analysis of latitudinal trends, confined by data limitations, was equivocal on a global scale. While significant latitudinal differences existed in community structure among ecoregions, a semi-linear trend in changing community structure from the Arctic to lower latitudes did not hold when including tropical results. Among boreal regions the Canadian Atlantic was relatively species poor compared to the Gulf of Alaska, whereas the Caribbean and Sea of Japan appeared to be species hot spots. While species poor, samples from the Canadian Atlantic were the most diverse at the higher infraordinal level. Linking 11 environmental variables available for all sites to the best fit family-based biotic pattern showed a significant relationship, with the single best explanatory variable being the level of organic pollution and the best combination overall being organic pollution and primary productivity. While data limitations restrict conclusions in a global context, results are seen as a first-cut contribution useful in generating discussion and more in-depth work in the still poorly understood field of biodiversity distribution.

    A series of ambiguous features on the seafloor off the coast of Provincetown, Massachusetts USA has been identified in two bathymetric lidar surveys (2007, 2010) conducted by the US Army Corps of Engineers. Similar features in the area have been described as linear scour depressions by other investigators, but at deeper water depths. These features exhibit some of the characteristics of bedforms, they have migrated tens of meters and maintained similar 3 dimensional morphologies. However, what would be described as the slipface more closely resembles the updrift face of a linear scour depression. The features are in relatively shallow water (9 - 15 m), are 150 - 200 m long, have spacings of 100 - 150 m and are 5-6 m in height. Further investigations are being undertaken to better understand these features and nearshore sediment transport in the area. The features appear along a high energy, accreting coast with both strong wave-driven sediment flux and tidal currents. Mapping of the study area with an interferometric sonar system, which collects coincident swath bathymetry and acoustic backscatter imagery, is ongoing. Interferometric sonar increases bathymetric swath width to depth ratios, in comparison to multibeam systems, and expedites data collection by reducing costs, vessel-time and hazards associated with navigating shallow waters. In addition, sediment grab samples and a series of seismic reflection profiles will also be collected in the area to ground-truth acoustic imagery and provide a subsurface framework for the features, respectively. These datasets will allow investigators to better document bottom conditions, estimate flow velocities needed to create these features and improve our understanding of sediment transport processes and pathways in the area.

  15. Survey of the state of the art in near-shore pipeline location and burial assessment

    SciTech Connect

    1991-11-01

    Project's objective is to evaluate state-of-the-art methods for locating pipelines in shallow (less than 15 ft) water and for determining and monitoring their burial depths. The following recommendations are made on the research needed in three areas for locating near-shore, shallowly buried pipelines: (1) Sensors: The pipeline industry has selected the magnetic gradiometer array (GA) as a preferred sensor method. Other potential methods exist as backups. No additional research is recommended. (2) Remotely Operated Vehicles (ROVs): The Pipeline Research Committee is pursuing development of a prototype ROV is deliver the GA or other similar equipment to pipeline locations. (3) Phenomena: The data being collected from research on the phenomena affecting seabed conditions and the bathymetric data being collected along the Gulf Coast should be synthesized. This new effort should focus on identifying erosion-prone areas with respect to present and potential future pipeline locations. Technical approach is to get the broadest perspective on the concerns related to the determination of burial conditions for offshore pipelines, Argonne National Laboratory (ANL) contacted individuals and organizations from the gas and petroleum industries, hardware and software vendors, academicians, and representatives from the government. A literature survey yielded the names of persons within academia who are presently working on similar applications with sensors. In the oil and gas industry, individuals and organizations involved in the Pipeline Research Committee made extensive contributions to the review and also provided the names of meaningful contacts from among their vendors. Discussions were held with the various persons both on the telephone and face to face. Vendors provided background materials and overview presentations on their capabilities for ANL to review.

  16. Dynamics of a nearshore bar system in the northern Adriatic: A video-based morphological classification

    NASA Astrophysics Data System (ADS)

    Armaroli, Clara; Ciavola, Paolo

    2011-03-01

    The aim of this paper is to define a simplified morphodynamic classification suitable for low energy beaches exposed to microtidal conditions. The study site is located in the northern Adriatic (in Italy), it is an almost 2 km-long rectilinear beach bordered at the northern edge by coastal structures and at the southern end by a small river inlet. The mechanisms related to the evolution of the submerged part of the beach were derived from video-monitoring using Argus technology. The morphodynamic evolution of the system was studied using an automatic procedure on images for the characterisation of nearshore bars that showed good correspondence with hand-based (visual) interpretation. To apply this automatic procedure, the bar's plan crest shape was mapped using cross-shore pixel luminosity transects traced on time-averaged video images. A careful sensitivity analysis was undertaken to determine the best spacing between transects for the correct tracing of the shape of the bar crest. The error associated to a transect spacing every 25 m resulted in being comparable with the pixel resolution in the area and with the error found comparing the video interpretation with bathymetric surveys. From the study of a four and a half year dataset (February 2003-May 2007), the submerged beach was found to be characterised by the presence of a single bar in the area next to coastal protection structures. However, moving southwards of these, inner and outer bars were present. The morphodynamics of the outer bar and its plan shape modifications were dominated by rhythmic forms. Occasionally, after high energy events, the bar became rectilinear but during the following lower energy periods rhythmicity was re-established, supporting the hypothesis of self-organization mechanisms. The cross-shore position of the bar's crests only showed limited cross-shore mobility through time.

  17. Coral Colonisation of an Artificial Reef in a Turbid Nearshore Environment, Dampier Harbour, Western Australia

    A 0.6 hectare artificial reef of local rock and recycled concrete sleepers was constructed in December 2006 at Parker Point in the industrial port of Dampier, western Australia, with the aim of providing an environmental offset for a nearshore coral community lost to land reclamation. Corals successfully colonised the artificial reef, despite the relatively harsh environmental conditions at the site (annual water temperature range 18-32°C, intermittent high turbidity, frequent cyclones, frequent nearby ship movements). Coral settlement to the artificial reef was examined by terracotta tile deployments, and later stages of coral community development were examined by in-situ visual surveys within fixed 25 x 25 cm quadrats on the rock and concrete substrates. Mean coral density on the tiles varied from 113 ± 17 SE to 909 ± 85 SE per m2 over five deployments, whereas mean coral density in the quadrats was only 6.0 ± 1.0 SE per m2 at eight months post construction, increasing to 24.0 ± 2.1 SE per m2 at 62 months post construction. Coral taxa colonising the artificial reef were a subset of those on the surrounding natural reef, but occurred in different proportions—Pseudosiderastreatayami, Mycediumelephantotus and Leptastreapurpurea being disproportionately abundant on the artificial reef. Coral cover increased rapidly in the later stages of the study, reaching 2.3 ± 0.7 SE % at 62 months post construction. This study indicates that simple materials of opportunity can provide a suitable substrate for coral recruitment in Dampier Harbour, and that natural colonisation at the study site remains sufficient to initiate a coral community on artificial substrate despite ongoing natural and anthropogenic perturbations.

    2000-01-01

    A new remote sensing technique based on video image processing has been developed for the estimation of nearshore bathymetry. The shoreward propagation of waves is measured using pixel intensity time series collected at a cross-shore array of locations using remotely operated video cameras. The incident band is identified, and the cross-spectral matrix is calculated for this band. The cross-shore component of wavenumber is found as the gradient in phase of the first complex empirical orthogonal function of this matrix. Water depth is then inferred from linear wave theory's dispersion relationship. Full bathymetry maps may be measured by collecting data in a large array composed of both cross-shore and longshore lines. Data are collected hourly throughout the day, and a stable, daily estimate of bathymetry is calculated from the median of the hourly estimates. The technique was tested using 30 days of hourly data collected at the SandyDuck experiment in Duck, North Carolina, in October 1997. Errors calculated as the difference between estimated depth and ground truth data show a mean bias of -35 cm (rms error = 91 cm). Expressed as a fraction of the true water depth, the mean percent error was 13% (rms error = 34%). Excluding the region of known wave nonlinearities over the bar crest, the accuracy of the technique improved, and the mean (rms) error was -20 cm (75 cm). Additionally, under low-amplitude swells (wave height H ???1 m), the performance of the technique across the entire profile improved to 6% (29%) of the true water depth with a mean (rms) error of -12 cm (71 cm).

    This report presents socio-economic profiles of the counties in the Puget Sound Area of the Washington-Oregon Planning Area of the Minerals Management Service. The Puget Sound Area includes Whatcom, Skagit, Snohomish, King, Pierce, Thurston, Mason, and Kitsap counties. It presents baseline socio-economic profiles of coastal counties in Washington, Oregon, and California which may be potentially affected by offshore oil and gas development. Each profile includes socio-economic characteristics organized under the following eight headings: demographics, economics, housing, public services and facilities, public finance, energy consumption, land use, and other characteristics. The focus of each socio-economic profile is 1980, but the time period 1970 to 2000 is covered, to the extent possible with existing data, to provide a historical context and an understanding of expected trends. Each county's socio-economic profile was prepared using time-series data from secondary sources obtained primarily from federal, state, and local government agencies.
