Report on treatability test of groundwater by ultraviolet (uv)/oxidation, Umatilla Depot Activity, Hermiston, Oregon. Final report, July 1991-June 1995  

SciTech Connect

The Report on the Treatability Test of Groundwater by Ultraviolet (UV)/Oxidation has been prepared for the U.S. Army Environmental Center (USAEC), to document the results of the treatability test performed at Umatilla Depot Activity (UMDA), Hermiston, Oregon, during the Site 4 (Explosive Washout Lagoons) pumping tests. The objective of the treatability test was to gather data to evaluate whether UV/ozone is a feasible alternative for effectively removing explosives from groundwater at Site 4. The report presents discussions on the treatment technology, field setup, sampling/analyses, results, and useability. The results indicate that most explosives were effectively treated by UV/ozone, but that 1,3,5-trinitrobenzene (1,3,5-TNB) was difficult to treat. Projected costs for a full-scale treatment system are provided. In addition, an evaluation of a field method for analyzing explosives in groundwater which was performed in conjunction with the treatability testis presented.

Resource Contingency Program - Oregon : Final Environmental Impact Statement, Hermiston Power Project.  

SciTech Connect

The Bonneville Power Administration (BPA) has statutory responsibilities to supply electrical power to its utility, industrial, and other customers in the Pacific Northwest. In 1990, to cover the outer range of potential load growth with new resources, BPA embarked upon the Resource Contingency Program (RCP). Instead of buying or building generating plants now, BPA has purchased options to acquire power later, if and when it is needed. The decision to acquire any of these option energy projects to fulfill statutory supply obligations will be influenced by Federal system load growth, the outcome of BPA`s Business Plan, required operational changes in Columbia-Snake River Hydroelectric facilities, and the loss of major generating resources. In September 1993, three option development agreements were signed with three proposed natural gas-fired, combined cycle combustion turbine CT projects near Chehalis and Satsop, Washington, and near Hermiston, Oregon. Together these three projects could supply BPA with 1,090 average megawatts (aMW) of power. Under these agreements, sponsors are obtaining permits and conducting project design work, and BPA is completing this EIS process. In September 1993, BPA published a Notice of Intent to prepare an environmental impact statement (EIS) on these three proposed gas-fired combustion turbine projects and held public scoping meetings in October 1993 at each site. In February 1994, BPA released an Implementation Plan on the proposed scope of the EIS. A draft EIS on the three proposed projects was published in February 1995. The impacts of the Chehalis and Satsop projects located in Washington State will be covered in one EIS document, while the impacts of the Hermiston project located in Oregon are covered in this final EIS document. It is BPA`s intent to continue to base the analysis of impacts on the assumption that all three projects may be constructed at some point in the future.

Physical activity as a trigger of sudden cardiac arrest: The Oregon Sudden Unexpected Death Study?  

PubMed Central

Background Sudden cardiac arrest (SCA) is a significant public health problem and better understanding of triggers could enhance prevention. Vigorous physical activity has been suggested as a prominent trigger but has not been welcvaluated in the general population. We performed a community-based study to analyze the role of physical activity as a potential trigger of SCA. Methods Medical records of 1180 subjects who sustained SCA during the ongoing Oregon Sudden Unexpected Death Study (Multnomah County, Oregon, USA; 2002–05) were reviewed. Analysis was limited to first responder and hospital records of patients who experienced witnessed SCA, with information available regarding physical activity immediately prior to SCA. An estimated metabolic equivalent (MET) score was used to classify levels of physical activity. Results A total of 304 adults met criteria for analysis (mean age 69 years, 67% male). The majority (n=193, 63%) were performing light activities, 51 (17%) subjects were sleeping, 39 (13%) were performing moderate activities, 14 (5%) were performing heavy activities, and 7 (2%) were engaged in sexual activity. Light activities were associated with older age (72 years) and heavy activities with the youngest (51 years, p<0.001). Males were more likely to be involved in heavy activity (93% male) and the sexual activity group was exclusively male ( p=0.04). Conclusion Vigorous physical activity was a potential trigger of SCA in a minority (5%). The vast majority (80%) of subjects were asleep or were performing light activities. The traditional view of SCA triggers may have to be re-visited, with renewed focus on factors such as emotional stress and sleep-related disorders.

Integrating computational activities into the upper-level Paradigms in Physics curriculum at Oregon State University  

NASA Astrophysics Data System (ADS)

The Paradigms in Physics project at Oregon State University has reformed the entire upper-level physics curriculum. The reform has involved a rearrangement of content to better reflect the way physicists think about the field and the use of several new pedagogies that place responsibility for learning more firmly in the hands of the students. In particular, we employ a wide variety of computational examples and problems throughout the courses. Students use MAPLE, MATHEMATICA, JAVA, and other software packages to do calculations, visualizations, and simulations that develop their intuition and physical reasoning. These computational activities are indispensable to the success of the curriculum.

Bat activity in thinned, unthinned, and old-growth forests in western Oregon  

USGS Publications Warehouse

Many aspects of the influences of forest management activities on bats (Chiroptera) in the Pacific Northwest are poorly known. We compared thinned and unthinned forest stands of the same age and old-growth forest stands to determine potential differences in structure and amount of use by bats. We hypothesized that activity levels of bats would differ in stands differing in structure as a result of management history and that activity of bats would be similar in stands of similar structure. We used automated ultrasonic detectors (Anabat II) to record calls of bats in 50-100-year-old thinned and unthinned stands, and in old-growth (a?Y200 yr old) stands in the Oregon Coast Range during the summers of 1994 and 1995. Our median index of bat activity was higher in old-growth than in unthinned stands and higher in thinned than in unthinned stands. We were not able to detect a significant difference between the index of median bat activity for old-growth and thinned stands. More than 90% of identifiable passes were identified as calls from Myotis species. The 3 stand types we examined differed in certain structural characteristics such as density and size of trees, and amount of overstory and understory cover. We concluded that the structural changes caused by thinning may benefit bats by creating habitat structure in young stands that bats are able to use more effectively.

PURPOSE. To identify environmental barriers and facilitators of children's physical activity and healthy eating in a rural county. DESIGN. Community-based participatory research using mixed methods, primarily qualitative. SETTING. A rural Oregon county. SUBJECTS. Ninety-five adults, 6 high school students, and 41 fifth-grade students. MEASURES. In-depth interviews, focus groups, Photovoice, and structured observations using the Physical Activity Resource Assessment, System for Observing Play and Leisure Activity, Community Food Security Assessment Toolkit, and School Food and Beverage Marketing Assessment Tool. ANALYSIS. Qualitative data were coded by investigators; observational data were analyzed using descriptive statistics. The findings were triangulated to produce a composite of environmental barriers and assets. RESULTS. Limited recreational resources, street-related hazards, fear of strangers, inadequate physical education, and denial of recess hindered physical activity, whereas popularity of youth sports and proximity to natural areas promoted physical activity. Limited availability and high cost of healthy food, busy lifestyles, convenience stores near schools, few healthy meal choices at school, children's being permitted to bring snacks to school, candy used as incentives, and teachers' modeling unhealthy eating habits hindered healthy eating, whereas the agricultural setting and popularity of gardening promoted healthy eating. CONCLUSIONS. This study provides data on a neglected area of research, namely environmental determinants of rural childhood obesity, and points to the need for multifaceted and multilevel environmental change interventions.

Laboratory-based educational and outreach activities in the framework of a CAREER award at the University of Oregon  

NASA Astrophysics Data System (ADS)

The Stable Isotope Laboratory at the University of Oregon has been used as a learning and outreach center in the framework of the 09 award entitled "Stable isotope insights into large-volume volcanic eruptions". The PI and other members of the group have actively recruitted undergraduate students, summer session and catalytic outreach undergraduates, and hosted international students, visitors, and collaborators from Russia, Iceland, France, the UK, Australia, and Switzerland. We also integrated closely with the Oregon-wide summer program that brings community college students to the University of Oregon for 2.5 months summer research residence (UCORE). In total we gave supervised five undergraduate students and three UCORE students. Additionally, we recruited undergraduates from U of Chicago, Colorado and Pomona Colleges to spend summers in the lab and in the field. In conjunction with the NSF funded PIRE program, two female graduate and one female undergraduate students participated in fieldwork in Kamchatka, and three Kamchatka undergraduates, and one Moscow graduate student visited the University Oregon. Students performed their own projects or Senior Theses and reported their results locally and at AGU conferences. We developed a management structure in which graduate students, a postdoc, and lab technician co-supervised students and visitors and this exposed them into the supervisory roles, contributed to the project progress, and liberated PI from micromanagement duties. The talk will present our experience with this management concept of a lab-based-learning initiative, which defines roles for each member of the lab. Our outreach activities included public lectures at community colleges by PI and a graduate student, and the topical Penrose conference co-organized by the PI, which attracted many students and visitors who collected their data in the lab. PI has introduced a voluntary fieldtrip as a part of his Volcanoes and Earthquake large enrollment class for non-majors. PI had less success in an attempt to involve non-geoscience majors into an optional satellite class due to the low interest among non-majors to explore geological and volcanological topics. Students in the Isotope Geochemistry and General Geochemistry classes used the Stable Isotope laboratory for their course papers, mostly related to the analyses of carbonate for isotopes of carbon and oxygen (paleoclimate projects), and using oxygen and hydrogen isotopes for sources of precipitation. Overall CAREER award provided excellent chance for multi-dimensional research that cross cut international boundaries, brings new projects in and contributes to the educational development of the PI and his group.

Activity patterns of marbled murrelets in Douglas-fir old-growth forests of the Oregon Coast Range  

USGS Publications Warehouse

We monitored activity patterns of Marbled Murrelets (Brachyramphus marmoratus) on a near-dailyb asisu singa udio-visuasl urveys during three breeding seasons at five forest stands in the Oregon Coast Range. Three measures of activity were recorded: number of daily detections, number of daily vocalizations, and duration of daily activity. Each measure was highly variable within and among stands and years, and we recorded greater variability than has been previously reported for this species. The three measures of activity were strongly correlated within a day at each survey station, but correlative relationships at temporal and spatial scales greater than this were inconsistent. Activity varied greatly from one day to the next during all portions of the breeding season, and we did not identify any month when variability in activity was consistently higher or lower than any other month. Multivariate analyses revealed that weather and date variates explained little of the variability in daily activity. Given the extreme levels of variability in Marbled Murrelet activity and our lack of understanding as to which factors drive that variability, it is critical that conclusions about activity or behavior not be drawn from data sets not specifically designed to answer the questions of interest.

Stratigraphic development and hydrothermal activity in the Central Western Cascade Range, Oregon  

NASA Astrophysics Data System (ADS)

Two volcanic sequences bounded by erosional unconformities compose the stratigraphy of the North Santiam mining district, Western Cascade Range, Oregon. Diorite, granodiorite, and leucocratic quartz porphyry dikes, stocks, and sills intrude the breccias, flows, and tuffs of a volcanic center in the older Sardine Formation. Tourmaline-bearing breccia pipes are associated with the porphyritic granodiorite intrusions. An erosional unconformity separates the Sardine Formation from the overlying Elk Lake formation. The alteration patterns in the two formations are consistent with the development of hydrothermal systems during the eruption of each formation. However, the development of the two hydrothermal systems is separated by a period of erosion of the older volcanic pile. Early formation of mineralization that resembles porphyry copper deposits occurred within the Sardine Formation, and later, after eruption of the Elk Lake formation, epithermal veins and alteration developed along faults, fractures, and the margins of dikes in the Sardine Formation.

A major goal of this experiment is to detect kilometersize magma chambers in the upper crust below Newberry Volcano (Figure 1). The planned experiment is a small-scale version of one type of seismic-imaging experiment proposed by the Program for Array Seismic Studies of the Continental Lithosphere (PASSCL). Because of the required density of the recording array, the USGS recording effort will be concentrated in and around the summit caldera and leave ample opportunity for additional recording of the large shots, by interested parties, to study the rest of the volcano and surrounding geologic provinces.

Historic and recent patterns of dissolved oxygen in the Yaquina Estuary (Oregon, USA): Importance of anthropogenic activities and oceanic conditions  

NASA Astrophysics Data System (ADS)

Spatial and temporal patterns of dissolved oxygen (DO) in Yaquina Estuary, Oregon (USA) are examined using historic and recent data. There was a significant increasing trend in DO in the upstream portion of the estuary during the years 1960-1985. Historically, minimum dry season (May-October) DO levels occurred about 20 km from the estuary mouth at warm water temperatures, near both point source discharges and where extensive log rafting occurred. Presently, there is a trend of increasing dry season DO with increasing distance from the mouth of the estuary. Minimum DO levels occur at cool water temperatures (˜8 deg C), suggesting that recently upwelled oceanic water from the shelf is the source of the low DO water. Recent time-series data (2001-2007) demonstrates that the water advected into the estuary from the coastal ocean has DO levels < 5 mg l -1 about 13% of the time during the dry season and that water temperature is a good indicator of the oceanic source. Similarity in the flood-tide DO and water temperature relationship between recent time-series data in Yaquina and in historic data from other estuaries suggests that the hypoxic conditions observed off the Oregon coast since 2002 may have occurred previously, especially during the 1950's-1960's. It is important to characterize the natural background DO levels for estuaries in the region to be able to separate anthropogenic from natural influences on DO.

Evaluation of Malolactic Bacteria Isolated from Oregon Wines †  

PubMed Central

Oregon is a cool wine-producing region where grapes characteristically contain high concentrations of organic acids. To reduce the natural acidity and increase the microbiological stability and flavor complexity of the wine, malolactic fermentation is encouraged. In this study, strains of Leuconostoc oenos indigenous to Oregon wines were evaluated for their suitability to conduct malolactic fermentation in Oregon wines. Tests determined the malolactic activity of the Oregon isolates in comparison with commercial strains ML-34, PSU-1, MLT-kli, and ens 44-40 under various temperature and pH conditions. Sensitivities to sulfur dioxide, ethanol, and fumaric acid also were determined. Two Oregon strains, Er-1a and Ey-2d, were selected for commercial winemaking tests because they had greater malolactic activity under conditions of low pH (3.0) and low temperature (15 and 8°C), respectively.

Hottest Oregon geothermal find  

NASA Astrophysics Data System (ADS)

A geothermal test hole drilled 810 m into the summit crater of Newberry Volcano in Oregon measured 190°C, the hottest temperature measured so far in an Oregon geothermal energy prospect. What's more, a high temperature gradient discovered in the lower sixth of the test hole may point to greater potential than was previously thought for geothermal energy in the Cascade Range.Scientists from the U.S. Geological Survey found that in the hole's lower 140 m the temperature rose at a rate equivalent to about 600°C per kilometer. The worldwide continental average is about 30°C per kilometer. Edward Sammel, a USGS hydrologist, is the leader of the geothermal drilling project at Newberry. David Blackwell of the Southern Methodist University made the temperature measurements in the hole.

DIAMOND PEAK WILDERNESS, OREGON.  

USGS Publications Warehouse

No metallic mineral resources were identified during a mineral survey of the Diamond Peak Wilderness in Oregon. Cinder cones within the wilderness contain substantial cinder resources, but similar deposits that are more accessible occur outside the wilderness. The area could have geothermal resources, but available data are insufficient to evaluate their potential. Several deep holes could be drilled in areas of the High Cascades outside the wilderness, from which extrapolations of the geothermal potential of the several Cascade wilderness could be made.

Status of Oregon's Bull Trout.  

SciTech Connect

Limited historical references indicate that bull trout Salvelinus confluentus in Oregon were once widely spread throughout at least 12 basins in the Klamath River and Columbia River systems. No bull trout have been observed in Oregon's coastal systems. A total of 69 bull trout populations in 12 basins are currently identified in Oregon. A comparison of the 1991 bull trout status (Ratliff and Howell 1992) to the revised 1996 status found that 7 populations were newly discovered and 1 population showed a positive or upgraded status while 22 populations showed a negative or downgraded status. The general downgrading of 32% of Oregon's bull trout populations appears largely due to increased survey efforts and increased survey accuracy rather than reduced numbers or distribution. However, three populations in the upper Klamath Basin, two in the Walla Walla Basin, and one in the Willamette Basin showed decreases in estimated population abundance or distribution.

The Oregon Geothermal Planning Conference  

SciTech Connect

Oregon's geothermal resources represent a large portion of the nation's total geothermal potential. The State's resources are substantial in size, widespread in location, and presently in various stages of discovery and utilization. The exploration for, and development of, geothermal is presently dependent upon a mixture of engineering, economic, environmental, and legal factors. In response to the State's significant geothermal energy potential, and the emerging impediments and incentives for its development, the State of Oregon has begun a planning program intended to accelerate the environmentally prudent utilization of geothermal, while conserving the resource's long-term productivity. The program, which is based upon preliminary work performed by the Oregon Institute of Technology's Geo-Heat Center, will be managed by the Oregon Department of Energy, with the assistance of the Departments of Economic Development, Geology and Mineral Industries, and Water Resources. Funding support for the program is being provided by the US Department of Energy. The first six-month phase of the program, beginning in July 1980, will include the following five primary tasks: (1) coordination of state and local agency projects and information, in order to keep geothermal personnel abreast of the rapidly expanding resource literature, resource discoveries, technological advances, and each agency's projects. (2) Analysis of resource commercialization impediments and recommendations of incentives for accelerating resource utilization. (3) Compilation and dissemination of Oregon geothermal information, in order to create public and potential user awareness, and to publicize technical assistance programs and financial incentives. (4) Resource planning assistance for local governments in order to create local expertise and action; including a statewide workshop for local officials, and the formulation of two specific community resource development plans. (5) Formulation and implementation of various statewide incentives; emphasis will be given to the recommendations of the Oregon Alternate Energy Development Commission and its Geothermal Task Force.

Pollution prevention practices in Oregon`s electronics industry  

SciTech Connect

The purpose of this research was to identify prevention strategies that are currently being used by the electronics industry in oregon and to assess the industry`s interest in switching to less hazardous practices. A survey was distributed to 180 businesses, including all companies affiliated with the Oregon Electronics Association, and additional electronics corporations listed in Oregon phone directories. Forty-seven percent of the respondents indicated that their organization had attempted substituting less hazardous compounds for those used previously. Factors influencing the movement towards cleaner practices included the desire to find safer products that work as well as current products, ethical concerns, and long term financial benefits. Common problems that discouraged the industry from changing to less hazardous practices included: (1) the new product did not function as well as the original material; (2) the respondents did not believe current practices were harmful; and, (3) initial costs were prohibitive. Representatives from within this industry are encouraged to share information about methodologies that have been successful, as well as strategies that may not have lead to intended goals; to clarify green terminology for use in this industry; and to establish a reward system for recognizing those who have instituted pollution prevention strategies into their operations.

Early chiropractic education in Oregon  

PubMed Central

Chiropractic education in the northwestern United States has its origins in the Marsh School & Cure in 1904. Most of the early schools were located in Portland, Oregon, including the D.D. Palmer College of Chiropractic (1908-1910), and several of these had merged by 1912 or 1913 to form the Pacific Chiropractic College, forerunner of today's Western States College. The latter was organized as a non-profit institution during the Great Depression, and struggled not only to survive but to create a higher standard. The early broad-scope of chiropractic training in the state probably encouraged the liberal scope of practice enjoyed in Oregon to this day.

Newberry Volcano—Central Oregon's Sleeping Giant  

USGS Publications Warehouse

Hidden in plain sight, Oregon's massive Newberry Volcano is the largest volcano in the Cascades volcanic arc and covers an area the size of Rhode Island. Unlike familiar cone-shaped Cascades volcanoes, Newberry was built into the shape of a broad shield by repeated eruptions over 400,000 years. About 75,000 years ago a major explosion and collapse event created a large volcanic depression (caldera) at its summit. Newberry last erupted about 1,300 years ago, and present-day hot springs and geologically young lava flows indicate that it could reawaken at any time. Because of its proximity to nearby communities, frequency and size of past eruptions, and geologic youthfulness, U.S. Geological Survey scientists are working to better understand volcanic activity at Newberry and closely monitor the volcano for signs of unrest.

Impacts of multispecies parasitism on juvenile Oregon coho salmon (Oncorhynchus kisutch) in Oregon  

USGS Publications Warehouse

We are studying the impacts of parasites on threatened stocks of Oregon coastal coho salmon (Oncorhynchus kisutch). In our previous studies, we have found high infections of digeneans and myxozoans in coho salmon parr from the lower main stem of West Fork Smith River (WFSR), Oregon. In contrast parr from tributaries of this river, and outmigrating smolts, harbor considerably less parasites. Thus, we have hypothesized that heavy parasite burdens in parr from this river are associated with poor overwintering survival. The objective of the current study was to ascertain the possible effects these parasites have on smolt fitness. We captured parr from the lower main stem and tributaries of WFSR and held them in the laboratory to evaluate performance endpoints of smolts with varying degrees of infection by three digeneans (Nanophyetus salmincola, Apophallus sp., and neascus) and one myxozoan (Myxobolus insidiosus). The parameters we assessed were weight, fork length, growth, swimming stamina, and gill Na+,K+-ATPase activity. We repeated our study on the subsequent year class and with hatchery reared coho salmon experimentally infected with N. salmincola. The most significant associations between parasites and these performance or fitness endpoints were observed in the heavily infected groups from both years. We found that all parasite species, except neascus, were negatively associated with fish fitness. This was corroborated for N. salmincola causing reduced growth with our experimental infection study. Parasites were most negatively associated with growth and size, and these parameters likely influenced the secondary findings with swimming stamina and ATPase activity levels.

Oregon's Toxic Household Products Law.  

PubMed

In 1991, Oregon became the first state in the U.S. to require the addition of an aversive agent to ethylene glycol-containing antifreeze and methanol-containing windshield wiper fluid. This new law, entitled "Toxic Household Products (THP) Act," was designed to reduce pediatric and animal poisonings from accidental ingestion of these two potentially lethal consumer automotive products. While not the stated intention of the law, addition of aversive agents to consumer automotive products could also reduce adult poisonings associated with intentional (suicides or alcoholics ingesting methanol-containing windshield wiper fluid) or accidental exposures. This law went into effect April 30, 1995, following settlement of a lawsuit brought by the Chemical Manufacturing Specialties Association (CSMA), a trade group representing the five largest manufacturers of ethylene glycol-based antifreeze in the U.S. This paper discusses the major policy issues that arose following the passage of Oregon's THP Act. Major provisions of the law are provided along with a discussion of CSMA's opposition to the Act's implementation. A description of the eventual settlement that was reached with CSMA as well as the major components of Oregon Health Division's (OHD) enforcement program are also highlighted. Data are presented for 1987 through 1998 on the number of exposures and severity of effects for pediatric cases (children < 6 years old) following exposure to both of these potentially lethal automotive products. However, because of the low incidence of exposures each year, these data are insufficient to draw any conclusions on the impact of the THP Act. PMID:11021047

Landslide assessment of Newell Creek Canyon, Oregon City, Oregon  

SciTech Connect

A study has been conducted in Newell Creek Canyon near Oregon City, Oregon, T3S, T2S, R2E. A landslide inventory has located 53 landslides in the 2.8 km[sup 2] area. The landslides range in area from approximately 15,000m[sup 2] to 10m[sup 2]. Past slides cover an approximate 7% of the canyon area. Landslide processes include: slump, slump-translational, slump-earthflow and earthflow. Hard, impermeable clay-rich layers in the Troutdale Formation form the failure planes for most of the slides. Slopes composed of Troutdale material may seem to be stable, but when cuts and fills are produced, slope failure is common because of the perched water tables and impermeable failure planes. Good examples of cut and fill failures are present on Highway 213 which passes through Newell Creek Canyon. Almost every cut and fill has failed since the road construction began. The latest failure is in the fill located at mile-post 2.1. From data gathered, a slope stability risk map was generated. Stability risk ratings are divided into three groups: high, moderate and low. High risk of slope instability is designated to all landslides mapped in the slide inventory. Moderate risk is designated to slopes in the Troutdale Formation greater than 8[degree]. Low risk is designated to slopes in the Troutdale Formation less than 8[degree].

Urban carbon dioxide in Portland, Oregon  

NASA Astrophysics Data System (ADS)

Ambient concentrations of atmospheric carbon dioxide (CO2) are reported for the Portland, Oregon (USA) metropolitan region since late July, 2009. Three stationary locations were established: a downtown location on the campus of Portland State University; a residential site in southeast Portland; and a rural station on Sauvie Island, located ~30km northwest of Portland in the Columbia River Gorge. Continuous measurements of CO2 at the sites average 400-410ppm and show considerable variability due to CO2 sources, sinks and meteorological drivers of ventilation. Within this variability, a marked 20-30ppm diurnal cycle is observed due to photosynthetic activity and variations in the planetary boundary layer. In-city CO2 concentrations are on average enhanced by 5-6ppm over the Sauvie Island site during upgorge wind conditions, a difference which is greatest in the afternoon. Measurements of the 13C/12C ratio of CO2 in downtown Portland are significantly depleted in 13C relative to 12C compared with background air and suggest that regional CO2 is dominated by petroleum sources (70-80%). High degrees of relationship between CO2 variability and primary air pollutants CO and NO (r2=0.70 to 0.80), measured by the Oregon Department of Environmental Quality at the Southeast Portland location, corroborate this finding and illustrate the importance of traffic emissions on elevated ambient CO2 concentrations. In addition to CO2 at the fixed sites, measurements of street-level CO2 concentrations were obtained using a mobile instrument mounted in a bike trailer. Results from these field data show relatively homogenous CO2 concentrations throughout residential Portland neighborhoods with significant enhancements in CO2 on busy roadways or near areas of traffic congestion.

Oregon Building Code Compliance Study.  

SciTech Connect

Compliance with Chapter 53 of the Oregon Building Code was studied through an examination of eight building department jurisdictions. The purpose of the study was to determine the 1983-1984 levels of residential compliance with Oregon's Energy Code (Chapter 53). Additionally, the study compares 1983-1984 compliance levels with 1980 compliance levels, analyzes factors which impact compliance, and makes recommendations for increasing levels of compliance. Eight jurisdictions were selected for the study. Through inspections of 129 completed homes and 30 partially completed homes, the level of code compliance was found to have increased since 1980 in many areas, including the application of attic and exterior wall insulation. Items in which little or no improvement was seen since a similar study in 1980 include application of underfloor insulation and the application of insulation around windows. Building officials, inspectors and plans examiners were interviewed. They identified underfloor insulation (32%), verifying the amount of attic blow-in insulation (62%) and vapor barriers (24%) as major problem areas in enforcing Chapter 53. Greatest compliance can be found in dampers, flat attics, cathedral ceilings, and exterior walls. The most poorly enforced element of the code is the posting of signs indicating the level of insulation and the type of ventilation system.

Klamath Falls geothermal field, Oregon  

SciTech Connect

Klamath Falls, Oregon, is located in a Known Geothermal Resource Area which has been used by residents, principally to obtain geothermal fluids for space heating, at least since the turn of the century. Over 500 shallow-depth wells ranging from 90 to 2,000 ft (27 to 610 m) in depth are used to heat (35 MWt) over 600 structures. This utilization includes the heating of homes, apartments, schools, commercial buildings, hospital, county jail, YMCA, and swimming pools by individual wells and three district heating systems. Geothermal well temperatures range from 100 to 230{degree}F (38 to 110{degree}C) and the most common practice is to use downhole heat exchangers with city water as the circulating fluid. Larger facilities and district heating systems use lineshaft vertical turbine pumps and plate heat exchangers. Well water chemistry indicates approximately 800 ppM dissolved solids, with sodium sulfate having the highest concentration. Some scaling and corrosion does occur on the downhole heat exchangers (black iron pipe) and on heating systems where the geo-fluid is used directly. 73 refs., 49 figs., 6 tabs.

Corrosion prevention of Oregon's reinforced coastal bridges  

SciTech Connect

The Oregon Department of Transportation (Oregon DOT) maintains more than 120 coastal bridges; many are reinforced concrete structures over 15 m (50 ft) in length. Twelve of these bridges are historic structures. Oregon DOT is concerned about the ongoing deterioration of these bridges, rising maintenance and repair costs, and the need to protect Oregon’s large investment in coastal bridges. Over 80,000 m2 (850,000 ft2) of coastal bridge surface have been repaired and protected from further chloride-induced corrosion damage by using conductive coating anodes. Most of the anode area is thermal-sprayed (TS) Zn. Other anode materials include TS Ti, Zn-hydrogel, and conductive carbon paint. TS Zn anodes are estimated to have a service life exceeding 25 years but exhibit increasing anode polarization with age. Catalyzed TS Ti anodes develop no significant anode polarization and have exhibited stable long-term performance over 8 years of service. Galvanic Zn-hydrogel anodes produce a stable protection current with no evidence of aging effects over 6 years of service. The conductive carbon paint anode operates at a low anode current density and consumption rate with a low rate of acidification at the anode-concrete interface, which has contributed to a stable protection current over 17 years of service.

Sprague River geomorphology studies, Klamath Basin, Oregon  

NASA Astrophysics Data System (ADS)

The Sprague River drains 4050 square kilometers with a mean annual discharge of 16.3 m3/s before emptying into the Williamson River and then upper Klamath Lake in southcentral Oregon. The alternating wide alluvial segments and narrow canyon reaches of this 135-km-long westward flowing river provide for a variety of valued ecologic conditions and human uses along the river corridor, notably fisheries (including two endangered species of suckers, and formerly salmon), timber harvest, agriculture, and livestock grazing. The complex history of land ownership and landuse, water control and diversion structures, and fishery alterations, provides several targets for attributing historic changes to channel and floodplain conditions. Recently, evolving societal values (as well as much outside money) are inspiring efforts by many entities to 'restore' the Sprague River watershed. In cooperation with the U.S. Fish and Wildlife Service, the Klamath Tribes, and many local landowners, we are launching an analysis of Sprague River channel and floodplain processes. The overall objective is to guide restoration activities by providing sound understanding of local geomorphic processes and conditions. To do this we are identifying key floodplain and channel processes, and investigating how they have been affected by historic floodplain activites and changes to the watershed. This is being accomplished by analysis of historic aerial photographs and maps, stratigraphic analysis of floodplain soils and geologic units, mapping of riparian vegetation conditions and changes, and quantitative analysis of high resolution LiDAR topography acquired for the entire river course in December 2004. Preliminary results indicate (1) much of the coarser (and more erodible) floodplain soils are largely composed of pumice deposited in the basin by the 7700 year BP eruption of Mount Mazama; and (2) the LiDAR digital elevation models provide a ready means of subdividing the river into segments with quantifiably different characteristics of channel width, sinuosity, slope, and incision (relative to adjacent floodplain elevations).

Petroleum potential of north-central Oregon: an overview  

SciTech Connect

Except for a few erosional inliers, north-central Oregon is covered by a blanket of tertiary volcanic and volcaniclastic rocks which had a thick sequence of Cretaceous and Tertiary sedimentary rocks that have led previous investigators to draw negative conclusions regarding the petroleum potential of the region. Present in the prevolcanic sequence are all the prerequisites for petroleum generation and accumulation: source rocks, thermal maturity, reservoir rocks, seals, and traps. Organic-rich source rocks include marine mudstones of the Lower Cretaceous Mitchell Formation black shales and coals of the Paleocene-Eocene Herren Formation, and lacustrine shales and coals of the Eocene-Oligocene Clarno Formation. The Type II and III kerogens are thermally mature. Petroleum seeps and shows are further evidence that hydrocarbons have been generated. Potential reservoir rocks include proximal fan facies and turbidite sandstones of the Mitchell Formation, fluvial channel sandstones of the Herren Formation volcaniclastic sandstones and fractured flows and ignimbrites in the Clarno and John Day Formations, and scoriaceous and brecciated flows in the Columbia River Basalt. Tuffaceous claystones form excellent seals. Traps of several kinds are present including large untested domes and anticlines, abundant fault traps, and facies traps in the interfingering sand-shale sequences. Thus, despite abundant volcanic activity and periodically rejuvenated tectonic activity, north-central Oregon has the potential to yield large quantities of both oil and gas.

Deep long-period earthquakes beneath Washington and Oregon volcanoes  

USGS Publications Warehouse

Deep long-period (DLP) earthquakes are an enigmatic type of seismicity occurring near or beneath volcanoes. They are commonly associated with the presence of magma, and found in some cases to correlate with eruptive activity. To more thoroughly understand and characterize DLP occurrence near volcanoes in Washington and Oregon, we systematically searched the Pacific Northwest Seismic Network (PNSN) triggered earthquake catalog for DLPs occurring between 1980 (when PNSN began collecting digital data) and October 2009. Through our analysis we identified 60 DLPs beneath six Cascade volcanic centers. No DLPs were associated with volcanic activity, including the 1980-1986 and 2004-2008 eruptions at Mount St. Helens. More than half of the events occurred near Mount Baker, where the background flux of magmatic gases is greatest among Washington and Oregon volcanoes. The six volcanoes with DLPs (counts in parentheses) are Mount Baker (31), Glacier Peak (9), Mount Rainier (9), Mount St. Helens (9), Three Sisters (1), and Crater Lake (1). No DLPs were identified beneath Mount Adams, Mount Hood, Mount Jefferson, or Newberry Volcano, although (except at Hood) that may be due in part to poorer network coverage. In cases where the DLPs do not occur directly beneath the volcanic edifice, the locations coincide with large structural faults that extend into the deep crust. Our observations suggest the occurrence of DLPs in these areas could represent fluid and/or magma transport along pre-existing tectonic structures in the middle crust. ?? 2010 Elsevier B.V.

Seaside, Oregon, Tsunami Vulnerability Assessment Pilot Study  

NASA Astrophysics Data System (ADS)

The results of a pilot study to assess the risk from tsunamis for the Seaside-Gearhart, Oregon region will be presented. To determine the risk from tsunamis, it is first necessary to establish the hazard or probability that a tsunami of a particular magnitude will occur within a certain period of time. Tsunami inundation maps that provide 100-year and 500-year probabilistic tsunami wave height contours for the Seaside-Gearhart, Oregon, region were developed as part of an interagency Tsunami Pilot Study(1). These maps provided the probability of the tsunami hazard. The next step in determining risk is to determine the vulnerability or degree of loss resulting from the occurrence of tsunamis due to exposure and fragility. The tsunami vulnerability assessment methodology used in this study was developed by M. Papathoma and others(2). This model incorporates multiple factors (e.g. parameters related to the natural and built environments and socio-demographics) that contribute to tsunami vulnerability. Data provided with FEMA's HAZUS loss estimation software and Clatsop County, Oregon, tax assessment data were used as input to the model. The results, presented within a geographic information system, reveal the percentage of buildings in need of reinforcement and the population density in different inundation depth zones. These results can be used for tsunami mitigation, local planning, and for determining post-tsunami disaster response by emergency services.

Abstract Data from the primarily upwelling-favorable summer seasons of 1998, 1999 and 2000 were analyzed to determine basic cross-shelf and alongshelf current characteristics of the Oregon inner shelf. Two aspects of this circulation were studied: the vertically-varyingcross-shelf circulation and its relationship to wind-driven Ekman transport, and alongshore transport and its tendency to reverse during periods of weak winds. The cross-shelf

Geothermal research, Oregon Cascades: Final technical report  

SciTech Connect

Previous USDOE-funded geothermal studies have produced an extensive temperature gradient and heat flow data base for the State of Oregon. One of the important features identified as a result of these studies is a rapid transition from heat flow values on the order of 40 mW/m/sup 2/ in the Willamette Valley and Western Cascades to values of greater than or equal to100 mW/m/sup 2/ in the High Cascades and the eastern portion of the Western Cascades. These data indicate that the Cascade Range in Oregon has potential as a major geothermal province and stimulated much of the later work completed by government agencies and private industry. Additional data generated as a result of this grant and published in DOGAMI Open-File Report 0-86-2 further define the location and magnitude of this transition zone. In addition, abundant data collected from the vicinity of Breitenbush and Austin Hot Springs have permitted the formulation of relatively detailed models of these hydrothermal systems. These models are published in DOGAMI Open-File Report 0-88-5. Task 1.2 of the Deliverables section of Amendment M001 is fulfilled by DOGAMI publication GMS-48, Geologic map of the McKenzie Bridge quadrangle, Lane County, Oregon. This map was printed in October, 1988, and is part of the final submission to USDOE. 8 refs.

The Role of Earth Science in Oregon’s Tsunami Preparedness (Invited)  

NASA Astrophysics Data System (ADS)

Earth science played a critical role in understanding the scope of Oregon’s tsunami hazard. When in the early 1990’s earth scientists communicated to stakeholders the seriousness of the threat posed by local Cascadia subduction zone tsunamis, tsunami preparedness began to rise in priority at all levels of government. Hard field evidence in the form of prehistoric tsunami deposits was a critical component in making the hazard “real” to local governments. State-produced tsunami inundation maps derived from numerical simulations gave decision makers and educators reliable tools to illustrate the spatial scope of the hazard. These maps allowed local cities to plan for evacuation and empowered the State of Oregon to begin “hard” mitigation by limiting new construction of critical facilities seaward of a regulatory inundation line. “Entering” and “Leaving” tsunami hazard zone signs were placed along the Oregon Coast Highway where it dips below this inundation line as means of raising awareness of both the local and transient populations. When detailed inundation studies and derivative evacuation maps were produced for individual communities, State scientists sought advice from local officials at every stage, giving them ownership of the final products. This sense of ownership gave decision makers much greater confidence in the maps and turned many skeptics into passionate advocates. This network of advocates has, over time, resulted in local jurisdictions taking substantive preparedness actions such as replacing critical evacuation bridges, starting networks of emergency response volunteers, and moving critical structures like schools and fire stations. One place that earth science has some difficulty is in communicating probability and uncertainty. For example, the State of Oregon is currently producing new maps that depict uncertainty of tsunami flooding from a future Cascadia subduction zone earthquake. These maps show a range of inundation lines that reflect the relative confidence level (percentage) that a local Cascadia tsunami will NOT exceed each line. In the first of these studies at Cannon Beach, Oregon (Priest et al., 2009) the 90th percentile flood level was only about half to two-thirds as high as the 99th percentile. On the northern Oregon coast Cascadia recurrence is ~500 years, so a percentile map depicts spatial uncertainty of inundation for that event. A Cascadia tsunami approximating the 99th percentile confidence level is no doubt a rare event, but how rare we really do not know. We suspect from offshore turbidite data that only one of these extreme events may have occurred in the last 10,000 years. When the map and underlying data were presented to local officials, they had some difficulty in understanding how to use the information. Erring on the side of caution, they chose the 99th percentile line for evacuation planning but this decision greatly limited available evacuation sites. Cost may make a similarly conservative decision inappropriate for use in building codes or for design of vertical evacuation structures.

Quantitative Mineralogical Characterization of Oregon Erionite  

NASA Astrophysics Data System (ADS)

Erionite has been classified as Group-I Human Carcinogen by the IARC Working Group. Fibrogenetic potential of erionite varies from low to high yield of mesothelioma. This may require quantitative characterization of physicochemical properties of erionite before any experimental design. The toxicity of the mineral is such that quantitative characterization of erionite is extremely important. Yet, often the erionite specimens were incompletely or incorrectly characterized throwing doubt on the results of the work. For example, none of the Turkish erionite published until recently had balance error (E%) less than 10%, and Mg cation of the type specimen of erionite-Ca from Maze, Niigita Prefecture, Japan is more than 0.8. In the present study, erionite sample near Rome, Oregon have been quantitatively characterized using powder x-ray diffraction, Reitveld refinement, scanning electron microscopy, energy dispersive spectroscopy, inductively coupled plasma - mass spectroscopy, and Massbauer spectroscopy. The cell parameters of the erionite-K from Oregon is computed as a=13.2217(2) Å and c=15.0671 Å; chemical composition of the erionite as major oxides, rare earth elements and other trace elements, are characterized quantitatively. Crystal chemistries of the erionite are computed based upon the quidelines of the IMAA zeolite report of 1997.

Northeast Oregon Hatchery Project, Final Siting Report.  

SciTech Connect

This report presents the results of site analysis for the Bonneville Power Administration Northeast Oregon Hatchery Project. The purpose of this project is to provide engineering services for the siting and conceptual design of hatchery facilities for the Bonneville Power Administration. The hatchery project consists of artificial production facilities for salmon and steelhead to enhance production in three adjacent tributaries to the Columbia River in northeast Oregon: the Grande Ronde, Walla Walla, and Imnaha River drainage basins. Facilities identified in the master plan include adult capture and holding facilities; spawning incubation, and early rearing facilities; full-term rearing facilities; and direct release or acclimation facilities. The evaluation includes consideration of a main production facility for one or more of the basins or several smaller satellite production facilities to be located within major subbasins. The historic and current distribution of spring and fall chinook salmon and steelhead was summarized for the Columbia River tributaries. Current and future production and release objectives were reviewed. Among the three tributaries, forty seven sites were evaluated and compared to facility requirements for water and space. Site screening was conducted to identify the sites with the most potential for facility development. Alternative sites were selected for conceptual design of each facility type. A proposed program for adult holding facilities, final rearing/acclimation, and direct release facilities was developed.

Bed-material, channel stability, and regional gravel production dynamics in Oregon coastal rivers  

NASA Astrophysics Data System (ADS)

Along the Oregon coast, gravel-bed rivers of various basin sizes and network topologies carve their way to the Pacific Ocean through a suite of geologic formations and land-use activities. To date, we have initiated assessments of bed-material condition and channel stability for seven coastal Oregon rivers (from north to south: Nehalem, Tillamook, Umpqua, Coquille, Rogue, Hunter, and Chetco). These river channels are of interest, in part, due to historic and on-going removal of gravels for commercial aggregate. Gravel extraction alone or in conjunction with the effects of other land uses may initiate a variety of channel changes, leading to channel instability. For each river, we synthesize multiple lines of evidence (including field observations, particle measurements, GIS analyses, specific gage analyses, and previous studies) to determine if the river channels are in equilibrium, degrading, or aggrading and if bed-material transport is likely limited by transport capacity or sediment supply. Initial field observations include the presence of reaches with some channel instability (mainly aggradation and channel widening) in the Hunter, Rogue, and Coquille basins. Our preliminary specific gage analyses indicate changes in the stage-discharge relationships at several gages, including a long-term gage on Rogue River near Grants Pass, where the channel has either incised or widened, resulting in a lowering of stage over time and different discharges. Building on our preliminary findings and review of the literature, we postulate that gravel production in coastal Oregon rivers is a function of the surrounding geology, basin slope, annual precipitation rates, channel bed elevation patterns (e.g., the length of the channel bed at sea level), and network structure. Bed-material supply tends to be greatest for rivers draining the Klamath terrane. Preliminary statistical analyses also show that the product of basin slope and mean annual precipitation describes 57% of the variation for specific bed-material yield measured for 20 rivers in southwest Oregon and northwest California. Laboratory experiments are underway to detect relative differences in sediment abrasion rates between the major geologic provinces of the Oregon coast so that attrition rates can be better considered in developing local bed-material sediment budgets. With this work, we aim to develop a regional understanding of gravel production and transport in these Oregon coastal rivers in order to facilitate on-going research into gravel transport and channel dynamics and, ultimately, adaptive management of gravel resources in these rivers.

Oregon Trail Mushrooms geothermal loan guaranty application, Malheur County, Oregon: Environmental assessment  

SciTech Connect

The action assessed is the guaranty of a loan by the Geothermal Loan Guaranty Office of the US Department of Energy (DOE) to finance the construction and operation of a mushroom-growing facility that will use geothermal (hot) water for process and space heat. The project consists of two separate facilities: a growing facility located just outside of the eastern limit of the city of Vale, Oregon (Malheur County, Oregon) and a composting facility located about 6.4 km (4 miles) southwest of the city limits (also in Malheur County, Oregon). Five test wells have been drilled into the geothermal resource at the growing site. Either well No. 4 or well No. 5 will serve as a production well. All geothermal fluids will be reinjected into the geothermal aquifer, so either well No. 3 will be used for this purpose, wells Nos. 1 and 2 will be deepened, or a new well will be drilled on the site. A cold-water well will be drilled at the growing site, and another will be drilled at the composting site. The environmental effects of the proposed project are not expected to be significant.

Their nest, built on a 90-foot power pole near the twin bridges over the Willamette River, could be seen by many commuters on their way in and out of town. After the 2002 nesting season, the nest was moved a short distance downriver to a constructed nesting platform because sticks sometimes dropped from the huge nest onto power lines below and caused power outages. At the new location, the pair can once again raise a family of young, their general well being monitored by the 50,000 residents of the community.

Varicella surveillance in public elementary schools--Multnomah County, Oregon, 2002-2004.  

PubMed

Varicella vaccination of school-aged children reduces the number of varicella cases and lost days of school. In 1996, the Advisory Committee on Immunization Practices (ACIP) recommended routine vaccination of all children aged 12-18 months, catch-up vaccination of all susceptible children before age 13 years, and vaccination of susceptible persons who have close contact with persons at high risk for serious complications and susceptible persons at high risk for exposure. In 1999, ACIP updated these recommendations to include vaccination requirements for child care and school entry. Since 2000, in accordance with ACIP recommendations, varicella vaccination requirements have been phased in for Oregon children who have not had varicella before starting out-of-home child care, kindergarten, or seventh grade; elementary school children will be fully covered by school year (SY) 2006-07. To monitor changes in varicella incidence, Oregon Health Services (OHS) and Multnomah Education Service District (MESD) started routine, individual, case-based varicella surveillance in Multnomah County public elementary schools (kindergarten through 5th grade) beginning SY 2002-03. This report describes the surveillance system, the incidence of varicella during SY 2002-03 and SY 2003-04, and the results of active surveillance for unidentified cases during SY 2002-03. The findings indicate that the number of varicella cases has decreased in Oregon and that establishing public elementary school-based varicella surveillance is feasible and useful. PMID:15788993

Estimating Flow-Duration and Low-Flow Frequency Statistics for Unregulated Streams in Oregon  

USGS Publications Warehouse

Flow statistical datasets, basin-characteristic datasets, and regression equations were developed to provide decision makers with surface-water information needed for activities such as water-quality regulation, water-rights adjudication, biological habitat assessment, infrastructure design, and water-supply planning and management. The flow statistics, which included annual and monthly period of record flow durations (5th, 10th, 25th, 50th, and 95th percent exceedances) and annual and monthly 7-day, 10-year (7Q10) and 7-day, 2-year (7Q2) low flows, were computed at 466 streamflow-gaging stations at sites with unregulated flow conditions throughout Oregon and adjacent areas of neighboring States. Regression equations, created from the flow statistics and basin characteristics of the stations, can be used to estimate flow statistics at ungaged stream sites in Oregon. The study area was divided into 10 regression modeling regions based on ecological, topographic, geologic, hydrologic, and climatic criteria. In total, 910 annual and monthly regression equations were created to predict the 7 flow statistics in the 10 regions. Equations to predict the five flow-duration exceedance percentages and the two low-flow frequency statistics were created with Ordinary Least Squares and Generalized Least Squares regression, respectively. The standard errors of estimate of the equations created to predict the 5th and 95th percent exceedances had medians of 42.4 and 64.4 percent, respectively. The standard errors of prediction of the equations created to predict the 7Q2 and 7Q10 low-flow statistics had medians of 51.7 and 61.2 percent, respectively. Standard errors for regression equations for sites in western Oregon were smaller than those in eastern Oregon partly because of a greater density of available streamflow-gaging stations in western Oregon than eastern Oregon. High-flow regression equations (such as the 5th and 10th percent exceedances) also generally were more accurate than the low-flow regression equations (such as the 95th percent exceedance and 7Q10 low-flow statistic). The regression equations predict unregulated flow conditions in Oregon. Flow estimates need to be adjusted if they are used at ungaged sites that are regulated by reservoirs or affected by water-supply and agricultural withdrawals if actual flow conditions are of interest. The regression equations are installed in the USGS StreamStats Web-based tool (http://water.usgs.gov/osw/streamstats/index.html, accessed July 16, 2008). StreamStats provides users with a set of annual and monthly flow-duration and low-flow frequency estimates for ungaged sites in Oregon in addition to the basin characteristics for the sites. Prediction intervals at the 90-percent confidence level also are automatically computed.

Methanogenic Diversity in Marine Sediments at Hydrate Ridge, Oregon  

NASA Astrophysics Data System (ADS)

Little is known about the mechanism of methanogenic degradation of acetate or the fate of hydrogen and formate in cold marine sediments, or the ability of methanogens to grow and produce methane there. We used cultivation and molecular techniques to examine the microbes that produce methane from these substrates in permanently cold, anoxic marine sediments at Hydrate Ridge, Oregon (44° 35'N, 125° 10'W, depth 800 m). Sediment samples (15 to 35 cm deep) were collected from areas of active methane ebullition or areas where methane hydrates occurred. The samples were anoxically diluted and inoculated into enrichment media with formate, acetate, or trimethylamine as catabolic substrate. After 2 years incubation at 4° C to 15° C, enrichment cultures grew and produced methane. DNA was extracted from the highest dilutions that grew. The sequence data suggested that each enrichment culture contained a single strain of methanogen, and many of these sequences were dissimilar to known sequences of methanogens. This level of similarity (89 to 91% similar) suggests that these methanogens belong to novel genera. A clone library of 16S rRNA genes was also created from DNA extracted from the sediment samples. Analysis of the 16S rRNA gene libraries also revealed phylotypes that were only distantly related to cultivated organisms. The sequences of the clone library and of the enrichment cultures indicate a high degree of phylogenetic diversity among the Hydrate Ridge Archaea.

Gravity model studies of Newberry Volcano, Oregon  

SciTech Connect

Newberry, Volcano, a large Quaternary volcano located about 60 km east of the axis of the High Cascades volcanoes in central Oregon, has a coincident positive residual gravity anomaly of about 12 mGals. Model calculations of the gravity anomaly field suggest that the volcano is underlain by an intrusive complex of mafic composition of about 20-km diameter and 2-km thickness, at depths above 4 km below sea level. However, uplifted basement in a northwest trending ridge may form part of the underlying excess mass, thus reducing the volume of the subvolcanic intrusive. A ring dike of mafic composition is inferred to intrude to near-surface levels along the caldera ring fractures, and low-density fill of the caldera floor probably has a thickness of 0.7--0.9 km. The gravity anomaly attributable to the volcano is reduced to the east across a north-northwest trending gravity anomaly gradient through Newberry caldera and suggests that normal, perhaps extensional, faulting has occurred subsequent to caldera formation and may have controlled the location of some late-stage basaltic and rhyolitic eruptions. Significant amounts of felsic intrusive material may exist above the mafic intrusive zone but cannot be resolved by the gravity data.

Dynamical behavior in linearly coupled Oregonators  

NASA Astrophysics Data System (ADS)

Tyson [Ann. NY Acad. Sci. 316 (1979) 279] conjectured that the stable homogeneous positive steady state may coexist with stable echo wave (meaning anti-phase wave) in linearly coupled Oregonators (and thus gave a conjecture on the bifurcation diagram of this system). In this paper, we rigorously prove stability of the in-phase wave and existence of the anti-phase wave. Our proof procedure actually gives a general method (or line) to deal with the analogous problem. For instance, to prove stability of the in-phase wave, following our line one may decompose the corresponding variational equations (a four-dimensional system) into two independent planar systems; also for instance, existence of the anti-phase wave can be concluded as existence and uniqueness of limit cycle of the associate oscillator. In addition, according to parameter regimes of existence of the anti-phase wave and the stable homogeneous positive steady state, we give their coexistence regime and specify it, and in particular give the regime of the coupled coefficient. The specified results show that the theoretical results are in good accord with Tyson's numerical results.

Development of a Bird Integrity Index: Measuring Avian Response to Disturbance in the Blue Mountains of Oregon, USA  

NASA Astrophysics Data System (ADS)

The Bird Integrity Index (BII) presented here uses bird assemblage information to assess human impacts to 28 stream reaches in the Blue Mountains of eastern Oregon. Eighty-one candidate metrics were extracted from bird survey data for testing. The metrics represented aspects of bird taxonomic richness, tolerance or intolerance to human disturbance, dietary preferences, foraging techniques, and nesting strategies that were expected to be positively or negatively affected by human activities in the region. To evaluate the responsiveness of each metric, it was plotted against an index of reach and watershed disturbance that included attributes of land use/land cover, road density, riparian cover, mining impacts, and percent area in clearcut and partial-cut logging. Nine of the 81 candidate bird metrics remained after eliminating unresponsive and highly correlated metrics. Individual metric scores ranged from 0 to 10, and BII scores varied between 0 and 100. BII scores varied from 78.6 for a minimally disturbed, reference stream reach to 30.4 for the most highly disturbed stream reach. The BII responded clearly to varying riparian conditions and to the cumulative effects of disturbances, such as logging, grazing, and mining, which are common in the mountains of eastern Oregon. This BII for eastern Oregon was compared to an earlier BII developed for the agricultural and urban disturbance regime of the Willamette Valley in western Oregon. The BII presented here was sensitive enough to distinguish differences in condition among stream riparian zones with disturbances that were not as obvious or irreversible as those in the agricultural/urban conditions of western Oregon.

Oregon Low-Temperature-Resource Assessment Program. Final technical report  

SciTech Connect

Numerous low-temperature hydrothermal systems are available for exploitation throughout the Cascades and eastern Oregon. All of these areas have heat flow significantly higher than crustal averages and many thermal aquifers. In northeastern Oregon, low temperature geothermal resources are controlled by regional stratigraphic aquifers of the Columbia River Basalt Group at shallow depths and possibly by faults at greater depths. In southeastern Oregon most hydrothermal systems are of higher temperature than those of northeastern Oregon and are controlled by high-angle fault zones and layered volcanic aquifers. The Cascades have very high heat flow but few large population centers. Direct use potential in the Cascades is therefore limited, except possibly in the cities of Oakridge and Ashland, where load may be great enough to stimulate development. Absence of large population centers also inhibits initial low temperature geothermal development in eastern Oregon. It may be that uses for the abundant low temperature geothermal resources of the state will have to be found which do not require large nearby population centers. One promising use is generation of electricity from freon-based biphase electrical generators. These generators will be installed on wells at Vale and Lakeview in the summer of 1982 to evaluate their potential use on geothermal waters with temperatures as low as 80/sup 0/C (176/sup 0/F).

Emergency Contraception in Emergency Departments in Oregon, 2003  

PubMed Central

Objectives. We sought to learn about access to emergency contraception (EC) in Oregon emergency departments, both for women who are rape patients and for women who have had consensual unprotected sexual intercourse (“nonrape patients”). Methods. We interviewed emergency department staff in 54 of Oregon’s 57 licensed emergency departments in February–March 2003 (response rate = 94.7%). Results. Only 61.1% of Oregon emergency departments routinely offered EC to rape patients. Catholic hospitals were as likely as non-Catholic hospitals to routinely offer EC to rape patients. The hospitals most likely to routinely offer EC to rape patients had a written protocol for the care of rape patients that included offering EC (P = .02) and access to staff with specialized sexual assault training (P=.002). For nonrape patients, 46.3% of emergency departments discouraged the prescribing of EC. Catholic hospitals were significantly less likely than non-Catholic hospitals to provide access to EC for nonrape patients (P=.05). Conclusions. Oregon emergency departments do not routinely offer EC to women who have been raped or to women who have had consensual unprotected sexual intercourse.

Understanding Community Wind Energy Development in Oregon: An Integrated Analysis  

NASA Astrophysics Data System (ADS)

This research intends to provide insights into community wind energy development in Oregon using an integrated analysis approach, which incorporates GIS Suitability Analysis, Socio-Political Analysis, and Empirical Case Studies. In the GIS analysis, we developed a model through a series of steps (including data acquisition, preprocessing, data management, manipulation and analysis, and output generation) to measure how suitable a location is for developing wind energy in Oregon. The socio-political analysis adopts the Socio-Political Evaluation of Energy Deployment (SPEED) framework and categorized policies and incentives that are applicable to community wind projects into three classes: strategic, tactical, and operational. The empirical case studies, focused on seven projects in Oregon, are analyzed using the actor-network theoretical framework, and their opportunities and barriers are explored as well.

Decline and present status of breeding peregrine falcons in Oregon  

USGS Publications Warehouse

In 1979, only one Peregrine Falcon pair (they fledged two young) and a single adult male were located. A population decline east of the Cascades began in rhe 1930's, probably resulting from a climatic change (drought); however, a statewide decline began in the late 1940's, accelerated in the 1950's, and by the 1960's few pairs remained. The statewide decline closely paralleled the pattern of DDT use. Furthermore, DDE was found in membranes of peregrine eggs from nearby California as early as 1948. Moreover, an unhatched Peregrine Falcon egg found at the Oregon eyrie in 1979 contained 19 ppm DDE and lesser amounts of other contaminants. The eggshell was 19% thinner than normaL The future of the nearly extirpated Peregrine Falcon in Oregon remains uncertain in spite of improved water and habitat conditions in eastern Oregon. Reintroduction of captive-bred birds seems to be the last hope.

Paleomagnetism in Central Oregon Cascade Basalts  

NASA Astrophysics Data System (ADS)

Twelve Pleistocene-aged basalt flows near McKenzie Bridge in Central Oregon were sampled and the paleomagnetic stratigraphy recorded in the rocks analyzed. The purpose of the study is to examine tectonic crustal motions since eruption of these flows, paleosecular variation during their eruption, and/or a record of a field reversal. The lavas were chosen because they appear to be the right age to record the Matuyama-Brunhes reversal and record both normal and reverse polarity fields (Conrey, pers comm). Four to six samples from each flow were analyzed using stepwise alternating field demagnetization, effecting a neutralization of any secondary magnetism the rock had recorded since its formation. Two samples from each site were heated and demagnetized in a rock oven to give clues to the magnetic mineralogy of the basalt as well as giving another look at the primary thermal remanent magnetization. Thermal demagnetization data suggests the primary source of magnetism is from titanomagnetite. Samples will be analyzed by scanning electron microscope and reflected light microscopy to determine precise magnetic mineralogy. The mean site direction from all twelve flows shows a field with D = 327.1°, I = 59.8°, and a95 = 5.36°. The Virtual Geomagnetic Pole (VGP) from this data lies in Siberia (long. 151.8°, lat. 65.5° N. The expected mean direction for the McKenzie Bridge area, assuming that all measurements of the field over time will eventually result in a magnetic pole resting at the geographical north pole, would have a declination of 0° and an inclination of 63.4°. Several possibilities could account for the declination difference and low-latitude VGP. The first is that the flows sampled do not represent a long enough period of time for the true average geomagnetic field to be measured, and the paleopole was at the resultant VGP position during the eruption of the flows. The second explanation is that the McKenzie Bridge area basalts may have been rotated counter-clockwise since their formation. Finally, the section may record a portion of a reversal. The Siberian location of the VGPs lies along a suggested longitudinal preferred path for poles during reversals (eg. Love, 1998) and in one of Hoffman's (1996) patches. A concurrent study of underlying basalt flows produced similar results (White and Valentine, this volume). Further study of the rest of this section should help determine the cause of the directional anomaly.

Electrical structure of Newberry Volcano, Oregon  

NASA Astrophysics Data System (ADS)

From the interpretation of magnetotelluric, transient electromagnetic, and Schlumberger resistivity soundings, the electrical structure of Newberry Volcano in central Oregon is found to consist of four units. From the surface downward, the geoelectrical units are (1) very resistive, young, unaltered volcanic rock, (2) a conductive layer of older volcanic material composed of altered tuffs, (3) a thick resistive layer thought to be in part intrusive rocks, and (4) a lower-crustal conductor. This model is similar to the regional geoelectrical structure found throughout the Cascade Range. Inside the caldera, the conductive second layer corresponds to the steep temperature gradient and alteration minerals observed in the USGS Newberry 2 test hole. Drill hole information on the south and north flanks of the volcano (test holes GEO N-1 and GEO N-3, respectively) indicates that outside the caldera the conductor is due to alteration minerals (primarily smectite) and not high-temperature pore fluids. On the flanks of Newberry the conductor is generally deeper than inside the caldera, and it deepens with distance from the summit. A notable exception to this pattern is seen just west of the caldera rim, where the conductive zone is shallower than at other flank locations. The volcano sits atop a rise in the resistive layer, interpreted to be due to intrusive rocks. The intrusive material has served as a heat source to produce enhanced hydrothermal alteration and, perhaps in the case of the west-flank anomaly, elevated fluid temperatures. While no public drill hole information is available to confirm this hypothesis, the west-flank anomaly appears to be a good geothermal target. In addition to the possibility that a region on the west side of the volcano could be favorable for prospecting, part of the resistive structure under the center of the volcano could be due to a vapor-dominated environment with temperatures above 300°C. In other parts of the Cascades, pervasive alteration has produced mixed layer clays and zeolites, resulting in low-resistivity anomalies. Low resistivities cannot be assumed to indicate high-temperature pore fluids. The use of electrical methods that measure resistivity as a function of excitation frequency, such as spectral induced polarization, may provide a way of obtaining information about the type and extent of alteration.

Idor Idaho-Oregon Earthscope Project: Deformation and Modification of a Steep Continental Boundary  

NASA Astrophysics Data System (ADS)

The IDOR project is an integrated study of the tectonic boundary between Precambrian North America and accreted terranes (island arcs of the Blue Mountains) in the Idaho-Oregon region. Its goal is to determine how the accretionary edge of the continental margin formed and was subsequently modified by deformation and magmatism. The margin contains unusually sharp isotopic gradients (Sr, O) representing the edge of Precambrian continental crust. This isotopic break correlates with a lithospheric-scale shear zone (western Idaho shear zone or WISZ) that formed in the mid Cretaceous in western Idaho. The WISZ is a major deformation zone characterized by a sequence of gneisses ~5 km thick and records transpressional deformation. The sharp isotopic gradient results, at least in part, from modification of the original Late Jurassic-Early Cretaceous suturing by the extreme shortening associated with the WISZ. The Idaho batholith, based on recent geochronology, was emplaced in multiple phases and is entirely east of the WISZ. The main batholith phase has no easily recognized mantle component, which contrasts markedly from other Cordilleran batholiths. Batholith emplacement occurred simultaneously with Sevier thrusting further east. Eocene (Challis) magmatism occurred throughout the region, both as localized centers and dike swarms. Miocene deformation and magmatism occurs throughout the region. A second sharp isotopic break is denoted by Miocene basaltic rocks, and is parallel to the sharp isotopic boundary in western Idaho (the exposed WISZ) but located ~120 km to the west. One hypothesis invoked to explain the repeated isotopic boundary is that a Sevier-age detachment cut and offset the WISZ, beheading it and leaving the WISZ’s root zone in eastern Oregon. Miocene magmatism, including the extrusion of the voluminous Columbia River basalts, appears localized on the sharp isotopic boundary in eastern Oregon. Extensional deformation, in contrast, appears partly localized on the WISZ in western Idaho. The IDOR project will investigate these issues through coordinated passive and active seismic (~500 km long line) deployments, geochemistry, geochronology, and structural geology.

Transverse structural trends along the Oregon convergent margin: Implications for Cascadia earthquake potential and crustal rotations  

SciTech Connect

A remarkable set of west-northwest-trending left-lateral strike-slip faults intersects the Cascadia subduction zone. Three of these faults have been mapped off northern and central Oregon by using seismic reflection, SeaMARC-1A sidescan sonar, and SeaBeam bathymetry. These faults are highly oblique to the north-south structural grain of the active accretionary wedge. One of them has 6 km of horizontal slip; the average slip rate is 7-10 mm/yr. The faults cut the subducting Juan de Fuca plate, and can be traced into the North American plate. Folds that deform late Pleistocene and Holocene sediments on the upper continental slope and shelf strike north-northwest to west-northwest. Some of the west-northwest-trending folds are associated with the throughgoing strike-slip faults, whereas other northwest-trending folds are approximately normal to the plate convergence direction. Many of these folds are mapped across the shelf, and several active shelf synclines project toward Oregon's coastal bays, where marsh subsidence events are inferred to be the result of great subduction-zone earthquakes. These subsidence events may actually record the growth of local synclines, possibly as secondary effects of slip on the megathrusts. The authors postulate that shortening of the forearc region by clockwise tectonic rotation, associated with movement of the left-lateral faults and folding of the upper plate, may accommodate a significant amount of plate convergence.

Stratigraphic and paleoecologic criteria that distinguish coseismically submerged from gradually submerged tidal wetland deposits, Oregon and Washington  

SciTech Connect

Widespread buried tidal-wetland soils exposed in outcrop in southern Washington and northern Oregon suggest that sudden coastal subsidence accompanied great (M>8) Cascadia subduction zone earthquakes at least twice in the past 2,000 years. But interpretation of the estuarine stratigraphic record along the subduction zone is complicated by the interplay of many coastal-sedimentation and sea-level factors found on passive as well as active continental margins. In this presentation, the author outlines-some simple models of sea-level and land-level change along subduction zone coasts, explain how these types of changes might be recorded in the tidal-wetland stratigraphic record, compare stratigraphies from the active-margin coasts of Oregon and Washington with stratigraphies from similar sites along passive continental margins in North America and Europe, and identify criterion that can help distinguish stratigraphic sequences produced by gradual sea-level change from those that may have been produced by coseismic subsidence. Field stratigraphic data alone are an inadequate basis for mapping the coastal extent of past great earthquakes -- only through detailed paleoecologic and dating analyses can one test proposed models of crustal subsidence and recovery during great earthquakes. Rigorous testing of such models is essential if the coastal paleoseismic record is to be used in forecasting the timing and magnitude of future subduction zone earthquakes in Oregon and Washington.

The IDES (Increasing Diversity in Earth Sciences) Program is the first partnership of its kind in the state of Oregon targeted at broadening participation in the Earth Science enterprise. Funded by the National Science Foundation Opportunities to Enhance Diversity in the Geosciences program (NSF-OEDG), this partnership involves community colleges, a research university with major strengths in Earth Science research and education and an institutionalized commitment to enhancing diversity, state and federal agencies, centers of informal education, and the Oregon Space Grant Consortium, IDES has two integrated goals: 1) to increase the number of students from under-represented groups who pursue careers in Earth Science research and education, and 2) to strengthen the understanding of Earth Sciences and their relevance to society among broad and diverse segments of the population. Built around the best practices of tiered mentoring, interactive student cohort, research and education internships, and financial support, this 4-year program recruits 10 to 12 students (mainly rising juniors) each year from science majors at Oregon State University and five Oregon community colleges. The program is reaching its goals by: a) training participants in the application of geospatial to Earth Science problems of personal relevance b) immersing participants in a two-year mentored research project that involves summer internships with academic units, state and federal agencies, and centers for informal education in Oregon. c) exposing, educating, and involving participants in the breadth of Earth Science careers through contact with Earth Science professionals through mentors, a professional internship, and a learning community that includes a speaker series. d) instilling an understanding of context and relevance of the Earth Science Enterprise to the participants, their families, their communities, and the general public. We report on the first two years of this program during which 20 participants have been involved and significant feedback has been received.

Geologic map of the Washougal quadrangle, Clark County, Washington, and Multnomah County, Oregon  

USGS Publications Warehouse

The Washougal 7.5’ quadrangle spans the boundary between the Portland Basin and the Columbia River Gorge, approximately 30 km east of Portland, Oregon. The map area contains the westernmost portion of the Columbia River Gorge National Scenic area as well as the rapidly growing areas surrounding the Clark County, Washington, cities of Camas and Washougal. The Columbia River transects the map area, and two major tributaries, the Washougal River in Washington and the Sandy River in Oregon, also flow through the quadrangle. The Columbia, Washougal, and Sandy Rivers have all cut deep valleys through hilly uplands, exposing Oligocene volcanic bedrock in the north part of the map area and lava flows of the Miocene Columbia River Basalt Group in the western Columbia River Gorge. Elsewhere in the map area, these older rocks are buried beneath weakly consolidated to well-consolidated Neogene and younger basin-fill sedimentary rocks and Quaternary volcanic and sedimentary deposits. The Portland Basin is part of the Coastal Lowland that separates the Cascade Range from the Oregon Coast Range. The basin has been interpreted as a pull-apart basin located in the releasing stepover between two en echelon, northwest-striking, right-lateral fault zones. These fault zones are thought to reflect regional transpression, transtension, and dextral shear within the forearc in response to oblique subduction of the Pacific plate along the Cascadia Subduction Zone. The southwestern margin of the Portland Basin is a well-defined topographic break along the base of the Tualatin Mountains, an asymmetric anticlinal ridge that is bounded on its northeast flank by the Portland Hills Fault Zone, which is probably an active structure. The nature of the corresponding northeastern margin of the basin is less clear, but a series of poorly defined and partially buried dextral extensional structures has been hypothesized from topography, microseismicity, potential-field anomalies, and reconnaissance geologic mapping. This map is a contribution to a program designed to improve the geologic database for the Portland Basin region of the Pacific Northwest urban corridor, the densely populated Cascadia forearc region of western Washington and Oregon. Updated, more detailed information on the bedrock and surficial geology of the basin and its surrounding area will facilitate improved assessments of seismic risk, and resource availability in this rapidly growing region.

Feasibility of a virtual health and wellness center for the Oregon Air National Guard.  

PubMed

A cross-sectional survey of members was used to examine the feasibility of developing a virtual health and wellness center in the Oregon Air National Guard. The survey asked about the health behaviors members wanted to change and explored their current access to, and potential use of, the Internet to make these changes. Surveys were mailed to 1,368 members, and 521 (38%) were returned. Most respondents (92.5%) had contemplated making one or more health behavior changes in the past year, which included becoming more physically active (94.6%), improving eating habits (86%), losing weight (81%), improving stress management (62%), and reducing tobacco use (46%). Popular sources of health behavior change information used included reading material (95.5%) and the Internet (91.3%). Many respondents had Internet access (82%), and average computer self-efficacy, rated on a scale of 1 to 5, was very high (mean = 4.05, SD = 0.91). Use of the Internet by health professionals to promote health behavior change among Oregon Air National Guard personnel seems feasible and desirable. PMID:11799811

High-resolution seismic tomography of compressional wave velocity structure at Newberry Volcano, Oregon Cascade Range  

SciTech Connect

Compressional wave velocity structure is determined for the upper crust beneath Newberry Volcano, central Oregon, using a high-resolution active-source seismic-tomography method. Newberry Volcano is a bimodal shield volcano east of the axis of the Cascade Range. It is associated both with the Cascade Range and with northwest migrating silicic volcanism in southeast Oregon. High-frequency (approx.7 Hz) crustal phases, nominally Pg and a midcrustal reflected phase, travel upward through a target volume beneath Newberry Volcano to a dense array of 120 seismographs. This arrangement is limited by station spacing to 1- to 2-km resolution in the upper 5 to 6 km of the crust beneath the volcano's summit caldera. The experiment tests the hypothesis that Cascade Range volcanoes are underlain only by small magma chambers. A small low-velocity anomaly delineated abosut 3 km below the summit caldera supports this hypothesis for Newberry Volcano and is interpreted as a possible magma chamber of a few to a few tens of km/sup 3/ in volume. A ring-shaped high-velocity anomaly nearer the surface coincides with the inner mapped ring fractures of the caldera. It also coincides with a circular gravity high, and we interpret it as largely subsolidus silicic cone sheets. The presence of this anomaly and of silicic vents along the ring fractures suggests that the fractures are a likely eruption path between the small magma chamber and the surface.

A tunnel runs through it--An inside view of the Tualatin Mountains, Oregon  

USGS Publications Warehouse

The Tualatin Mountains form a northwest-striking ridge about 350 m high that separates Portland, Oregon, from the cities of the Tualatin Valley to the west. Known informally as the Portland Hills, the ridge is a late Cenozoic anticline, bounded by reverse faults that dip toward the anticlinal axis. The anticline is a broad, open fold consisting chiefly of Miocene Columbia River Basalt Group, with remnants of Miocene-Pliocene Troutdale Formation and Pleistocene basalt of the Boring Volcanic Field on the flanks of the anticline. Anticlinal structures similar to the Tualatin Mountains are characteristic of the northern Willamette Valley, where the structures accommodate margin-parallel shortening of the Cascadia fore arc. Global Positioning System (GPS) results indicate that the shortening is due to the northward motion of Oregon at several millimeters per year with respect to stable North America. Some of the uplifts may contain active faults, but the structures are poorly exposed and are overlain by thick Pleistocene loess and Missoula flood deposits. Between 1993 and 1998, construction of the 3-mile-long (4500-m-long) TriMet MAX Light Rail tunnel through the Tualatin Mountains provided an unusual opportunity to investigate the geological structure and history of the Tualatin Mountains. This report is a collaborative effort among the tunnel geologists and the U.S. Geological Survey (USGS) to document the geologic story and quantify late Cenozoic and Quaternary deformation rates of the Tualatin Mountains.

Oil and gas developments in West Coast area in 1982. [Canada, Oregon, Washington  

SciTech Connect

Activity was brisk in the onshore area of California during 1982. Four hundred and seventy-five exploratory wells (41.4% successful) were drilled, including the discovery of 2 new oil and 4 new gas fields. The number of wells drilled decreased from a record 486 in 1981 to 475 in 1982; however, the total footage drilled increased from 2,711,217 ft in 1981 to 2,910,277 ft in 1982, and the average footage per well jumped sharply from 5,579 to 6,127 ft. In addition, 2,062 development wells were drilled (97.4% successfully). At various times during the year, up to 10 drilling vessels were active in state and federal waters. Four new offshore discoveries were announced by Texaco, Atlantic Richfield, Oxy, and Union. Texaco's ''Hueso'' discovery is a probable extension of the Chevron-Phillips Point Arguello field announced in October 1981. The field is believed to be a giant oil field containing over 100 million bbl of recoverable reserves. Union, Oxy, and Atlantic Richfield struck oil in the fractured Monterey Shale. Further delineation drilling will be needed to determine field reserves. California's total oil production for 1982 was 401.4 million bbl, a 4% increase from the 1981 record of 385 million bbl. Five unsuccesful wildcats were abandoned in Washington. Although there were some encouraging shows, the accumulations were deemed noncommercial. The bulk of drilling activity in Oregon centered around the Mist gas field. There were no discoveries announced for 1982. Geothermal activity in California was concentrated in The Geysers, Imperial Valley, and Coso areas. Oregon activity continued at the Newberry caldera.

Investigating the Processes of Crust Formation and Intraplate Continental Volcanism in the High Lava Plains, Oregon  

NASA Astrophysics Data System (ADS)

East of the southern Cascades is an area of voluminous Late-Cenozoic volcanism built on an immature crustal section accreted to North America in the Mesozoic. With the exception of the Snake River Plain, the High Lava Plains (HLP) of eastern Oregon has been the most volcanically active area in the western United States in the late Cenozoic. Through much of this area, the oldest exposed basement is early Miocene intermediate composition volcanic rocks. Beginning at approximately 16.5 Ma, the HLP was blanketed with flood basalts from both the Steens and Columbia River eruptive centers. The flood basalt era was followed by a time- progressive migration of large silicic centers beginning near the Oregon-Nevada-Idaho borders and extending to the present day activity at Newberry volcano. Quaternary basaltic volcanism is scattered along this whole trend, making the HLP more of a hot-line than a hot-spot. A variety of mechanisms have been proposed to explain this activity including: outflow of the Yellowstone plume-head, back-arc spreading, lithosphere delamination, Basin and Range extension, and asthenospheric inflow around the northward migrating edge of the subducting Juan de Fuca plate. These models make distinct predictions about the flow patterns and temperature structure of the shallow mantle underlying this area, but geophysical information capable of discriminating these models is sparse to absent. To remedy this situation and better define the causes of the voluminous volcanism in this area, the HLP project, funded by the NSF Continental Dynamics program, has initiated a multi-level broadband and active-source seismic study combined with field geology, geochemistry, petrology, geochronology and 3D geodynamic modeling of an area reaching from the southern Cascades across eastern Oregon into Idaho and northernmost Nevada. The seismic part of the project employs very dense station spacing that will provide high-resolution images of the crust and upper 100 km of the mantle, where USArray has only poor resolution. The geochemistry and petrology of the HLP volcanic rocks suggest that most of the magmatism originates in this shallow portion of the mantle and has substantially added to and modified the thin crust of the HLP.

Developing the Oregon Consortium for Nursing Education: the back story.  

PubMed

The Oregon Consortium for Nursing Education (OCNE) is a collaborative partnership between community colleges and a multicampus university in Oregon that developed in response to an emerging nursing shortage and changing health needs in the population. OCNE has created a redesigned curriculum with shared agreements for academic standards, admission, and seamless transition from associate to baccalaureate programs. Although the schools share pedagogical resources, curriculum, and standards, each partner school retains autonomy and accountability for its degree program. The creation and continued development of the consortium required the participation of people from multiple organizations with diverse concerns. Through a Robert Wood Johnson Foundation-funded evaluation of OCNE, this retrospective analysis was conducted to describe the process of consensus building that resulted in OCNE and to provide an explanatory framework for the benefit of others who are seeking to redesign nursing education in their communities.

Sedimentary response to eocene tectonic rotation in western Oregon  

NASA Astrophysics Data System (ADS)

Published paleomagnetic studies have shown that the Oregon Coast Range s rotated 60 degrees clockwise since middle Eocene time, probably by pivoting either during collision of a seamount terrane or during an episode of asymmetric extension within western North America. Eocene sedimentary deposits within the Oregon Coast Range basin, in particular the Tyee Formation, document changes in basin evolution that provide geologic constraints for proposed rotation models. The Tyee Formation comprises an arkosic petrofacies which is different from underlying lithic sandstones that were derived from the adjacent Klamath Mountains. Isotopic study of sandstones of the arkosic petrofacies, including Sm-Nd, Rb-Sr, K-Ar, and O 18 analyses indicate that much of the sandstone was not derived from the Klamath Mountains or nearby Sierra Nevada. The source area most likely included S-type granites of the Idaho Batholith.

Cost of Impressed Current Cathodic Protection for Coastal Oregon Bridges  

SciTech Connect

The State of Oregon is using arc-sprayed zinc coatings for anodes in impressed current cathodic protection (ICCP) systems on reinforced concrete coastal bridges. The two lowest bids for four ICCP projects were averaged and converted to 1997 dollars. The total average cost for the ICCP projects was $51.63/ft2 ($555.51/m2) of protected concrete. The cathodic protection part of the ICCP projects average $14.08/ft2 ($151.47/m2), while zinc anode installation cost an average of $7.13/ft2 ($76.67/m2). Oregon's rugged and beautiful coastline is graced with a series of historical arched bridges designed by Conde B. McCullough. McCullough is the internationally recognized architect who designed many of the Oregon Coast Highway (U.S. 101) bridges in the 1920s and 1930s. Many are listed on the National Historic Register. After the expense ($45m) and public outcry associated with the replacement of the historic Alsea Bay Bridge in Waldport, Oregon, the Oregon Department of Transportation began using impressed current cathodic protection (ICCP) to extend the service life of reinforced concrete bridges. Figure 1 visually illustrates the need for such remediation. It shows exposed rebar from underneath the Brush Creek Bridge, which is very representative of the conditions found underneath many coastal Oregon bridges. Four ICCP projects have been funded, put out for bid, and completed. The four projects, their bid closing dates, and their completion dates are the Cape Creek Bridge (1990- 1992), the Yaquina Bay Bridge south arches (1991-1995), the Depoe Bay Bridge (1993-1997), and the Yaquina Bay Bridge south approach (1995-1997). The Cape Creek, Yaquina Bay, and Depoe Bay Bridges are shown in Figs. 2-4. Other ICCP projects are underway on the Oregon coast. In the ICCP systems, arc-sprayed zinc coatings on the concrete surface are anodes that protect the steel rebar. Accelerated laboratory studies at the Albany Research Center have predicted zinc anode service lives of approximately 27 years based on long-term bond strength measurements.1-3 Experience in California4 has documented zinc anode service lives of over 11 years. Both indicate a substantial savings in project costs compared to bridge replacement. For example, the replacement cost of the arc-sprayed sections of the three Oregon bridges is estimated to be $57m, while the four ICCP projects on those bridges have cost $20m. (The $45m to replace the Alsea Bay Bridge was more than simply the replacement cost--it included expanding the bridge to four lanes and making the bridge ''ICCP ready'' by ensuring electrically continuous rebar).

Organochlorine residues and shell thinning in Oregon seabird eggs  

USGS Publications Warehouse

A single egg was collected at 62 nests of 10 seabird species from Oregon in 1979. The eggs were analyzed for organochlorine contaminants; contemporary shell thickness was compared with eggshells collected during earlier time periods. Concentrations of DDE and PCB's in 1979 were generally low with the most contaminated species being the Double-crested Cormorant (Phalacrocorax auritus), Leach's Storm Petrel (Oceanodroma leucorhoa), and Forktailed Storm Petrel (O. furcata). Limited eggshell data provide evidence that shell thinning was more severe along the Oregon coast in the 1950's than in 1979. With the possible exception of the Fork-tailed Storm Petrel, the residues in 1979 posed no known threat to the welfare of the species.

Eocene wave-dominated deltaic sedimentation, Oregon Coast Range  

SciTech Connect

The Eocene Tyee and Coaledo Formations of southwest Oregon together illustrate vertical and lateral facies changes in delta-front and prodelta-to-shelf deposits, which prograded into a forearc basin. Prevalent coarse sandstone bodies with wood also contain large-scale, contorted cross-bedding; they show north-northwest paleocurrent transport directions. An abundance of hummocky stratification and symmetrical ripples in the prodelta and shelf sandstones indicate the dominance of wavy processes. Wave-dominated deltaic deposition was a repetitive and persisting style of sedimentation throughout much of the Eocene period in southwest Oregon. This scenario is useful for distinguishing vertical and lateral relationships applicable to other ancient wave-dominated systems and to predictions in potentially economic units of the Pacific Northwest.

Hydrology of Spring-Dominated Streams in the Oregon Cascades  

NASA Astrophysics Data System (ADS)

Spring-dominated streams in the Oregon Cascades are often characterized by nearly constant discharge and by peak flows that occur in late summer or fall, several months after the annual snowmelt. A model is presented that can account for the temporal variations of discharge and the delay between snowmelt and the period of peak streamflow. Springs are assumed to be fed by an unconfined aquifer that is recharged by the annual snowmelt. Model results depend primarily on the effective permeability and the dimensions of the aquifer. Four spring-fed streams in the Deschutes River basin in the Oregon Cascades are studied. The effective permeability of the young (<2 Ma) volcanic rocks that comprise the aquifers is inferred to be O(10-11) m2.

Public health surveillance approaches in Oregon's Medicaid population.  

PubMed

The development of methods for public health surveillance in Medicaid populations is an important goal for public health practice. In Oregon, we developed approaches to case finding using claims and self-reported data obtained from the Medicaid beneficiary population. Disease rosters, derived from claims data, form the basis for analyses pertaining to particular health conditions. Self-reported information obtained through a telephone survey forms the basis for analyses pertaining to behavioral risk factors, disease history, and other information not available in claims data. We also describe some projects in which we plan to use combined claims and survey data. We describe our experiences with using these techniques and provide examples from projects in progress or planned. Our initial experiences suggest that these approaches enhance our ability to conduct public health surveillance in Oregon's Medicaid population. PMID:15156640

The passage and initial implementation of Oregon's Measure 44

OBJECTIVE—To prepare a history of the passage and early implementation of Ballot Measure 44, "An Act to Support the Oregon Health Plan", and tobacco control policymaking in Oregon. Measure 44 raised cigarette taxes in Oregon by US$0.30 per pack, and dedicated 10% of the revenues to tobacco control.?METHODS—Data were gathered from interviews with members of the Committee to Support the Oregon Health Plan, Measure 44's campaign committee, as well as with state and local officials, and tobacco control advocates. Additional information was obtained from public documents, internal memoranda, and news reports.?RESULTS—Although the tobacco industry outspent Measure 44's supporters 7 to 1, the initiative passed with 56% of the vote. Even before the election, tobacco control advocates were working to develop an implementation plan for the tobacco control programme. They mounted a successful lobbying campaign to see that the legislature did not divert tobacco control funds to other uses. They also stopped industry efforts to limit the scope of the programme. The one shortcoming of the tobacco control forces was not getting involved in planning the initiative early enough to influence the amount of money that was devoted to tobacco control. Although public health groups provided 37% of the money it cost to pass Measure 44, only 10% of revenues were devoted to tobacco control.?CONCLUSIONS—Proactive planning and aggressive implementation can secure passage of tobacco control initiatives and see that the associated implementing legislation follows good public health practice.???Keywords: advocacy; legislation; implementation; tobacco tax

Tectonic control of Eocene arkosic sediment deposition, Oregon and Washington  

SciTech Connect

Chronostratigraphic and geographic studies of Eocene arkosic sandstones suggest deposition during a volcanically quiet interval resulting from the westward jump of the Farallon-Kula plate subduction zone in Oregon and Washington. The Eocene arkosic sandstones were deposited as part of a broad fluvial plain-coastal plain-shelf margin basin complex extending throughout Oregon and Washington between uplands of Mesozoic rocks. Feldspathic-quartzose sediments were transported from the east by river systems draining granitic terrains perhaps as far away as the Idaho Batholith. Chronostratigraphic correlations suggest that the arkosic sandstones were deposited along the margins of the depositional system during the early Eocene, prograded westward during the middle Eocene, and then regressed during the latest Eocene and Oligocene simultaneously with the influx of abundant pyroclastic debris. During the early Eocene, a northwest-southeast seamount chain was extruded on the Farallon and Kula plates west of an eastward-dipping subduction zone. Subduction of the oceanic plates moved the seamount chain obliquely toward the subduction zone. In middle Eocene time-49 to 40 m.y.b.p-the seamount chain reached the subduction zone creating instability in the subduction system and resulting in the westward jump of the underthrust boundary between the Farallon-Kula and North American plates. Coincident with and continuing after the subduction zone jump and seamount accretion, eastwardly derived arkosic sediments prograded across Oregon and Washington spilling into the new fore-arc basin and enveloping the seamounts.

Integration of high-resolution seismic and aeromagnetic data for earthquake hazards evaluations: An example from the Willamette Valley, Oregon  

USGS Publications Warehouse

Aeromagnetic and high-resolution seismic reflection data were integrated to place constraints on the history of seismic activity and to determine the continuity of the possibly active, yet largely concealed Mount Angel fault in the Willamette Valley, Oregon. Recent seismic activity possibly related to the 20-km-long fault includes a swarm of small earthquakes near Woodburn in 1990 and the magnitude 5.6 Scotts Mills earthquake in 1993. Newly acquired aeromagnetic data show several large northwest-trending anomalies, including one associated with the Mount Angel fault. The magnetic signature indicates that the fault may actually extend 70 km across the Willamette Valley to join the Newberg and Gales Creek faults in the Oregon Coast Range. We collected 24-fold high-resolution seismic reflection data along two transects near Woodburn, Oregon, to image the offset of the Miocene-age Columbia River Basalts (CRB) and overlying sediments at and northwest of the known mapped extent of the Mount Angel fault. The seismic data show a 100-200-m offset in the CRB reflector at depths from 300 to 700 m. Folded or offset sediments appear above the CRB with decreasing amplitude to depths as shallow as were imaged (approximately 40 m). Modeling experiments based on the magnetic data indicate, however, that the anomaly associated with the Mount Angel fault is not caused solely by an offset of the CRB and overlying sediments. Underlying magnetic sources, which we presume to be volcanic rocks of the Siletz terrane, must have vertical offsets of at least 500 m to fit the observed data. We conclude that the Mount Angel fault appears to have been active since Eocene age and that the Gales Creek, Newberg, and Mount Angel faults should be considered a single potentially active fault system. This fault, as well as other parallel northwest-trending faults in the Willamette Valley, should be considered as risks for future potentially damaging earthquakes.

Geologic Map of the Camas Quadrangle, Clark County, Washington, and Multnomah County, Oregon  

USGS Publications Warehouse

The Camas 7.5' quadrangle is in southwestern Washington and northwestern Oregon approximately 20 km east of Portland. The map area, bisected by the Columbia River, lies on the eastern margin of the Portland Basin, which is part of the Puget-Willamette Lowland that separates the Cascade Range from the Oregon Coast Range. Since late Eocene time, the Cascade Range has been the locus of an episodically active volcanic arc associated with underthrusting of oceanic lithosphere beneath the North American continent along the Cascadia Subduction Zone. Bedrock consists largely of basalt and basaltic andesite flows that erupted during late Oligocene time from one or more vents located outside the map area. These rocks crop out only north of the Columbia River: at the base of Prune Hill in Camas, where they dip southward at about 5?; and east of Lacamas Creek, where they dip to the southeast at 15 to 30?. The volcanic bedrock is unconformably overlain by Neogene sediments that accumulated as the Portland Basin subsided. In the Camas quadrangle, most of these sediments consist of basaltic hyaloclastic debris generated in the volcanic arc to the east and carried into the Portland Basin by the ancestral Columbia River. The dominant structures in the map area are northwest-striking dextral strike-slip faults that offset the Paleogene basin floor as well as the lower part of the basin fill. The Oligocene rocks at Prune Hill and to the east were uplifted in late Pliocene to early Pleistocene time within a restraining bend along one of these dextral faults. In Pleistocene time, basaltic andesite flows issued from a volcano centered on the west side of Prune Hill; another flow entered the map area from the east. These flows are part of the Boring volcanic field, which comprises several dozen late Pliocene and younger monogenetic volcanoes scattered throughout the greater Portland region. In latest Pleistocene time, the Missoula floods of glacial-outburst origin inundated the Portland Basin. The floods deposited huge bars of poorly sorted gravel in the lee of Prune Hill and west of the Sandy River. Volcanic debris from Mount Hood form a prominent delta at the mouth of the Sandy River. This map is a contribution to a program designed to improve geologic knowledge of the Portland Basin region of the Pacific Northwest urban corridor, the densely populated Cascadia forearc region of western Washington and Oregon. More detailed information on the bedrock and surficial geology of the basin and its surrounding area is necessary to refine assessments of seismic risk, ground-failure hazards and resource availability in this rapidly growing region.

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.

Debating death: religion, politics, and the Oregon Death With Dignity Act.  

PubMed

In 1994, Oregon passed the Oregon Death With Dignity Act, becoming the first state in the nation to allow physician-assisted suicide (PAS). This paper compares the public discussion that occurred in 1994 and during the Act's implementation in 1997 and examines these debates in relation to health care reform under the Obama administration. I argue that the 1994 and 1997 Oregon PAS campaigns and the ensuing public debate represent the culmination of a growing lack of deference to medical authority, concerns with the doctor-patient relationship, and a desire for increased patient autonomy over decisions during death. The public debate over PAS in Oregon underscored the conflicts among competing religious, political, and personal interests. More visible and widespread than any other American debate on PAS, the conflict in Oregon marked the beginning of the now nationwide problem of determining if and when a terminally ill person can choose to die.

Legal physician-assisted suicide in Oregon and The Netherlands: evidence concerning the impact on patients in vulnerable groups--another perspective on Oregon's data.  

PubMed

Battin et al examined data on deaths from physician-assisted suicide (PAS) in Oregon and on PAS and voluntary euthanasia (VE) in The Netherlands. This paper reviews the methodology used in their examination and questions the conclusions drawn from it-namely, that there is for the most part 'no evidence of heightened risk' to vulnerable people from the legalisation of PAS or VE. This critique focuses on the evidence about PAS in Oregon. It suggests that vulnerability to PAS cannot be categorised simply by reference to race, gender or other socioeconomic status and that the impetus to seek PAS derives from factors, including emotional state, reactions to loss, personality type and situation and possibly to PAS contagion, all factors that apply across the social spectrum. It also argues, on the basis of official reports from the Oregon Health Department on the working of the Oregon Death with Dignity Act since 2008, that, contrary to the conclusions drawn by Battin et al, the highest resort to PAS in Oregon is among the elderly and, on the basis of research published since Battin et al reported, that there is reason to believe that some terminally ill patients in Oregon are taking their own lives with lethal drugs supplied by doctors despite having had depression at the time when they were assessed and cleared for PAS.

A Sediment Budget for the Deschutes River, Oregon  

NASA Astrophysics Data System (ADS)

The Deschutes River drains 28,000 km2 of north-central Oregon before joining the Columbia River 160 km east of Portland. Relicensing of Portland General Electric's Pelton-Round Butte complex, a set of three hydroelectric dams 160-180 km upstream from the Columbia River confluence, has motivated assessment of the roles of these impoundments as well as those of upstream dams on the volume of sediment available to the lower river. To accomplish this, we applied a relatively simple procedure of determining spatially explicit sediment yield by combining GIS-calculated indices of relative sediment production with sediment-yield measurements derived from reservoir surveys. Estimates of relative unit-area sediment production (sediment production index, SPI) were calculated for each of 100 similar sized subbasins on the basis of the product of the subbasin drainage density and mean hillslope gradient. Digital stream data were acquired from 1:100,000 hydrography, and mean hillslope gradients were determined from 30-meter resolution digital elevation data. Such an approach is reasonable for basins such as the Deschutes, where hillslope sediment transport is dominated by diffusive processes such as biogenic activity, rainsplash, soil creep, and freeze-thaw action, and, consequently, sediment flux per unit stream length is proportional to hillslope gradient. Calculated SPI values were empirically related to regional sediment yield by regressing against surveyed volumes of sediment accumulated in basin reservoirs, including the Deschutes and Crooked River arms of Lake Billy Chinook, Ochoco Reservoir, and Prineville Reservoir (in total, capturing sediment from about 60 percent of the entire Deschutes River watershed). The resulting regression is Qs = 3.74(SPI)2.13 (r2 = 0.98; p = 0.015), where Qs is sediment yield, in tonnes per square kilometer per year, and SPI is in units of km-1. This result is only strictly applicable to transported bedload and suspended sand and silt that drops out rapidly in these large reservoirs. Applying this relation to each of the 100 subwatersheds and cumulating the resulting estimates of sediment yield downstream allows for estimates of (1) the overall downstream sediment flux and (2) the incremental effects of impoundment in the Deschutes River basin. Under preimpoundment conditions, sediment flux at the Pelton-Round Butte Project site is estimated to be about 475,000 tonnes/yr. Downstream at the Columbia River confluence, total sediment flux was about 1,210,000 tonnes/yr, indicating that 60 percent of the preimpoundment sediment flux within the lower Deschutes River was derived from basin areas downstream of present impoundments. Of the 475,000 tonnes/yr now trapped by upstream impoundments, the Pelton-Round Butte project is responsible for about 225,000 tonnes/yr; the balance being primarily trapped in Ochoco and Prineville Reservoirs within the Crooked River drainage. This approach to determining regional sediment budgets could be easily applied to many other similar situations where changes in sediment flux due to river alterations and impoundments may have effects on river attributes and where sound mitigation strategies require quantitative understanding the magnitudes and locations of altered sediment regimes.

Relationship between carbonate deposits and fluid venting: Oregon Accretionary Prism  

NASA Astrophysics Data System (ADS)

Active fluid venting and its surface manifestations (unique animals and carbonates) occur over the accretionary prism in the Cascadia subduction zone located off central Oregon. A large variety of authigenic carbonate deposits and unique carbonate structures have been observed from submersibles and remotely operated vehicles and recovered with aid of submersibles and bottom trawls from the outermost continental shelf and lower continental slope. The carbonate deposits range from relatively thin crusts and slabs to irregular edifices and well-formed circular chimneys that rise from 1 to 2 m above the seafloor. Mineralogically, the carbonate cement consists of aragonite, calcite, Mg-calcite, or dolomite with varying amounts of detrital constituents. Stable carbon and oxygen isotope data identify four distinct subgroups of methane-derived carbonates from several different vent sites and different fluid source zones. Subgroup I represents one vent site on the lower slope and is characterized by oxygen isotope values ranging from +6.8‰ to +4.7‰ PDB. Subgroup II represents another vent site about 1 km away and exhibits oxygen values of +3.4‰ to +4.9‰ PDB. Carbon isotopic values range from -40.96 to -30.23‰ versus -44.26 to -53.44‰ PDB, respectively, for the two vents. An irregular edifice from the outer shelf has the same isotopic composition as subgroup II. A companion study shows that the expelled fluids contain largely biogenic methane and methane-derived dissolved carbonate; a shallow fluid source zone (<1 km) is indicated. The isotopic carbon values of the subgroup I and II carbonates are consistent with the carbon composition of the expelled fluids and apparently represent a historical record of the composition of these fluids. In subgroup III, strong 18O enrichment and heavier carbon values characterize the dolomitic chimneys from the outer continental shelf. Cemented sandstones from a "window" in the accretionary complex of the lower slope (subgroup IV) are characterized by extreme ?18O (-5.9 to -5.98 ‰) and moderate ?13C (-18.7 to -12.67‰)-depleted carbonates. This "light" oxygen isotope composition most likely originated from the upward migration of warm hydrothermal fluids along the main décollement, which tapped the warm subducting basaltic slab, during the early stages of formation of the accreted complex. Well-defined plumbing tubes within some carbonate chimneys on the shelf infer a single well-defined subsurface conduit with a fairly energetic fluid flow. The majority of the chimneys probably formed above the seafloor as long as the rate of carbonate precipitation exceeded the rate of detrital input during their formation. We calculate a minimum of one conduit for each 35 m2 at one vent site on the shelf. A less energetic flow is suggested by the chaotic plumbing network of an irregular edifice and by the widespread occurrence of the carbonate slabs and crusts at numerous vent sites.

Northeast Oregon Hatchery Project, Conceptual Design Report, Final Report.  

SciTech Connect

This report presents the results of site analysis for the Bonneville Power Administration Northeast Oregon Hatchery Project. The purpose of this project is to provide engineering services for the siting and conceptual design of hatchery facilities for the Bonneville Power Administration. The hatchery project consists of artificial production facilities for salmon and steelhead to enhance production in three adjacent tributaries to the Columbia River in northeast Oregon: the Grande Ronde, Walla Walla, and Imnaha River drainage basins. Facilities identified in the master plan include adult capture and holding facilities; spawning incubation, and early rearing facilities; full-term rearing facilities; and direct release or acclimation facilities. The evaluation includes consideration of a main production facility for one or more of the basins or several smaller satellite production facilities to be located within major subbasins. The historic and current distribution of spring and fall chinook salmon and steelhead was summarized for the Columbia River tributaries. Current and future production and release objectives were reviewed. Among the three tributaries, forty seven sites were evaluated and compared to facility requirements for water and space. Site screening was conducted to identify the sites with the most potential for facility development. Alternative sites were selected for conceptual design of each facility type. A proposed program for adult holding facilities, final rearing/acclimation, and direct release facilities was developed.

Model estimation of energy flow in Oregon coastal seabird populations  

USGS Publications Warehouse

A computer simulation model was used to explore the patterns and magnitudes of population density changes and population energy demands in Oregon populations of Sooty Shear-waters, Leach?s Storm-Petrels, Brandt?s Cormorants, and Common Murres. The species differ in seasonal distribution and abundance, with shearwaters attaining high densities during their migratory movements through Oregon waters, and murres exhibiting the greatest seasonal stability in population numbers. On a unit area basis, annual energy flow is greatest through murre and cormorant populations. However, because shearwaters occupy a larger area during their transit, they dominate the total energy flow through the four-species seabird ?community.?.....Consumption of various prey types is estimated by coupling model output of energy demands with information on dietary habits. This analysis suggests that murres annually consume nearly twice as many herring as any other prey and consume approximately equal quantities of anchovy, smelt, cod, and rockfish. Cormorants consume a relatively small quantity of bottom-dwelling fish, while stormpetrels take roughly equal quantities of euphausiids and hydrozoans. Anchovies account for 43% of the 62,506 metric tons of prey the four species are estimated to consume annually; 86% of this anchovy consumption is by shearwaters. The consumption of pelagic fishes by these four populations within the neritic zone may represent as much as 22% of the annual production of these fish.

Signature of El Nino off Oregon, 1982-1983  

SciTech Connect

Current and conductivity, temperature, and depth (CTD) measurements were made over the Oregon shelf near 43/sup 0/N between February 1981 and April 1984 as part of a large-scale west coast shelf experiment (SuperCODE). The data set includes a nearly continuous record of current velocity and temperature over the continental shelf off Coos Bay from May 1981 through January 1984, CTD sections off Coos Bay in January or February of each year from 1981 to 1984, and CTD sections off Newport (44.6/sup 0/N) in April 1983, and April 1984. The latter are compared with sections off Newport made during the previous two decades. Sea level from the Newport tide gage, daily sea surface temperature at Charleston (43.3/sup 0/N), the alongshore component of the wind stress at 45/sup 0/N and the large-scale North Pacific atmospheric pressure pattern provide a climatological perspective. The initial manifestation of El Nino off Oregon was in October 1982: anomalously high sea level, high coastal sea surface temperature, and increased poleward flow. These effects occurred within 1 month of the onset of El Nino off Peru and preceded any local (North Pacific) atmospheric effect by 2 to 3 months. The anomalous local meteorological conditions, which became manifest in December and January, greatly enhanced the initial effects and inserted their own signal. The first signals of El Nino probably arrived by an oceanic path, but there is no doubt they were subsequently reinforced by anomalous atmospheric conditions.

SciTech Connect

The John Day is the nation's second longest free-flowing river in the contiguous United States and the longest containing entirely unsupplemented runs of anadromous fish. Located in eastern Oregon, the basin drains over 8,000 square miles, Oregon's fourth largest drainage basin, and incorporates portions of eleven counties. Originating in the Strawberry Mountains near Prairie City, the John Day River flows 284 miles in a northwesterly direction, entering the Columbia River approximately four miles upstream of the John Day dam. With wild runs of spring Chinook salmon and summer steelhead, westslope cutthroat, and redband and bull trout, the John Day system is truly a basin with national significance. The majority of the John Day basin was ceded to the Federal government in 1855 by the Confederated Tribes of the Warm Springs Reservation of Oregon (Tribes). In 1997, the Tribes established an office in the basin to coordinate restoration projects, monitoring, planning and other watershed activities on private and public lands. Once established, the John Day Basin Office (JDBO) formed a partnership with the Grant Soil and Water Conservation District (GSWCD), which contracts the majority of the construction implementation activities for these projects from the JDBO. The GSWCD completes the landowner contact, preliminary planning, engineering design, permitting, construction contracting, and construction implementation phases of most projects. The JDBO completes the planning, grant solicitation/defense, environmental compliance, administrative contracting, monitoring, and reporting portion of the program. Most phases of project planning, implementation, and monitoring are coordinated with the private landowners and basin agencies, such as the Oregon Department of Fish and Wildlife and Oregon Water Resources Department. In 2003, the JDBO and GSWCD proposed continuation of their successful partnership between the two agencies and basin landowners to implement an additional twelve (12) watershed conservation projects. The types of projects include off channel water developments, juniper control, permanent diversions, pump stations, and return-flow cooling systems. Due to funding issues and delays, permitting delays, fire closures and landowner contracting problems, 2 projects were canceled and 7 projects were rescheduled to the 2004 construction season. Project costs in 2003 totaled $115,554.00 with a total amount of $64,981.00 (56%) provided by the Bonneville Power Administration (BPA) and the remainder coming from other sources such as the Bureau of Reclamation (BOR), Oregon Watershed Enhancement Board, the U.S. Fish & Wildlife Service Partners in Wildlife Program and individual landowners.

Geothermal gradient drilling, north-central Cascades of Oregon, 1979  

SciTech Connect

A geothermal gradient drilling program was conducted on the western flank of the north-central Cascade Mountains in Oregon. Six wells were drilled during this program, although in effect seven were drilled, as two wells were drilled at site 3, the second well, however, actually going to a lesser depth than the first. Three of the wells (3, 4, and 5) were drilled in areas which topographically are subject to strong throughflows of ground water. None of these wells reached the regional water table, and all showed essentially isothermal geothermal gradients. The single well which was started essentially at the water table (well 6) shows a linear temperature rise with depth essentially from the top of the well bore. Well No. 2 shows an isothermal gradient down to the level of the regional water table and then shows a linear gradient of about 70/sup 0/C/km from the regional water table to total depth.

Compositional zoning of the Devine Canyon Tuff, Oregon  

NASA Astrophysics Data System (ADS)

In eastern Oregon, many voluminous and minor rhyolites erupted from 40 Ma to 1.3 ka. As part of continued investigations into the petrogenesis of Oregon rhyolites, we focus here on the Devine Canyon Tuff (DCT). The 9.7 Ma DCT, with its proposed source in the Harney Basin, is among the most widespread ash flow tuffs in SE Oregon. It originally covered about 20,000 km2 with a minimum volume of 200 km3 as it flowed radially and eastward into the Oregon-Idaho graben. The DCT is crystal rich, pumiceous in places, and non- to densely welded with vitric, devitrified, and vapor phase zones. Pumices range in size from a few cm to about 30 cm and are rhyolitic with a very minor commingled dacite component. Phenocryst content ranges from 7% to 30%. Compositional zoning only becomes apparent by integrating data from several outcrops and therefore the tuff appears little zoned at the single outcrop scale. Published data and our work to date show that bulk tuff and pumices, excluding the commingled mafic component, are mildly peralkaline rhyolites (Na+K/Al = 1.0-1.2) with a limited range in major elements (SiO2, 74.6-77.6 wt%; and FeO*, 2.3-3.1 wt%), but vary greatly in the most incompatibe trace elements including Rb, Zr, Nb, Y. These elements indicate two-fold enrichments with the following concentrations in the least to most evolved samples: Rb from 80 ppm to 167 ppm, Zr from 599 ppm to 1,310 ppm, Nb from 48 ppm to 100 ppm, and Y from 81 ppm to 172 ppm. Other trace elements behave conservatively or decrease. LREE (e.g. Ce) concentrations decrease with differentiation pointing to the fractionation of LREE enriched phases causing rotation of REE patterns from the least (e.g. Ce/Y = 2.7) to most differentiated (Ce/Y = 1.1) samples. Compatible elements such as Ba and Sr range from 260 ppm to 10 ppm and 36 ppm to 3 ppm, respectively, but are more scattered suggesting that changes in alkali feldspar proportions influence concentration levels. Minerals include alkali feldspars, quartz, and minor hedenbergite and fayalitic olivine. Accessory phases include apatite, britholite, aenigmatite, chevkinite, Fe-Ti oxides, and zircon. Most feldspar are sanidine within the range of Ab34.7-61.8 Or34.7-61.8. Observed subtle changes in the mineral assemblages and compositions in different samples likely correlate with compositional changes of the magmas that will continue to be addressed in more detail. Glass analyses of shards, pumices, and quartz hosted melt inclusions mostly correspond with bulk analyses, but some pairs of bulk samples and their glassy components (e.g., the least evolved sample and one of the most evolved samples), have a wider range of major elements than other samples. Streaks of commingled mafic glass of select pumices are as mafic as 63.4 wt% SiO2, and 10.2 wt% FeO* indicating that strongly differentiated tholeiitic magma underlied the rhyolitic Devine Canyon magma and likely provided the thermal input for rhyolites to develop the observed zonations.

DEPOSITIONAL RELATIONS OF UMPQUA AND TYEE FORMATIONS (EOCENE), SOUTHWESTERN OREGON.  

USGS Publications Warehouse

The Umpqua Formation (as herein restricted) consists of as much as 10,000 ft of mudstone, sandstone, and conglomerate of nonmarine to deep marine origin. A basaltic basement that underlies the sedimentary rocks in most of the area and was formerly included in the Umpqua is herein considered a separate unit and assigned to the Siletz River Volcanics. A proposal to subdivide the Umpqua into three unconformity-bounded formations in the area west of Roseburg, Oregon, is not recognized in this report because of questionable correlations and limited extent of some units. The Tyee Formation, which conformably overlies the Umpqua, is a predominantly sandstone unit about 6,000 ft thick, deposited in environments ranging from shallow marine and nonmarine deltaic on the south, to slope and deep marine basinal to the north. Deposition across the Umpqua-Tyee boundary contact represents a change in tectonic setting. Refs.

Super-scale Failure of the Southern Oregon Cascadia Margin  

NASA Astrophysics Data System (ADS)

Using SeaBeam bathymetry and multichannel seismic reflection records we have identified three large submarine landslides on the southern Oregon Cascadia margin. The area enclosed by the three arcuate slide scarps is approximately 8000 km2, and involves an estimated 12,000-16,000 km3 of the accretionary wedge. The three arcuate slump escarpments are nearly coincident with the continental shelf edge on their landward margins, spanning the full width of the accretionary wedge. Debris from the slides is buried or partially buried beneath the abyssal plain, covering a subsurface area of at least 8000 km2. The three major slides, called the Heceta, Coos Basin and Blanco slides, display morphologic and structural features typical of submarine landslides. Bathymetry, sidescan sonar, and seismic reflection profiles reveal that regions of the continental slope enclosed by the scarps are chaotic, with poor penetration of seismic energy and numerous diffractions. These regions show little structural coherence, in strong contrast to the fold thrust belt tectonics of the adjacent northern Oregon margin. The bathymetric scarps correlate with listric detachment faults identified on reflection profiles that show large vertical separation and bathymetric relief. Reflection profiles on the adjacent abyssal plain image buried debris packages extending 20-35 km seaward of the base of the continental slope. In the case of the youngest slide, an intersection of slide debris and abyssal plain sediments, rather than a thrust fault, mark the base of slope. The age of the three major slides decreases from south to north, indicated by the progressive northward shallowing of buried debris packages, increasing sharpness of morphologic expression, and southward increase in post-slide reformation of the accretionary wedge. The ages of the events, derived from calculated sedimentation rates in overlying Pleistocene sediments, are approximately 110 ka, 450 ka, and 1210 ka. This series of slides traveled 25-70 km onto the abyssal plain in at least three probably catastrophic events, which may have been triggered by subduction earthquakes. The lack of internal structure in the slide packages, and the considerable distance traveled suggest catastrophic rather than incremental slip, although there could have been multiple events. The slides would have generated large tsunami in the Pacific basin, possibly larger than that generated by an earthquake alone. We have identified a potential future slide off southern Oregon that may be released in a subduction earthquake. The occurrence of the slides and subsequent subduction of the slide debris, along with evidence for margin subsidence implies that basal subduction erosion has occurred over at least the last 1 Ma. The massive failure of the southern Oregon slope may have been the result of the collision of a seamount province or aseismic ridge with the margin, suggested by the age progression of the slides and evidence for subducted basement highs. The lack of latitudinal offset between the oldest slide debris and the corresponding scarp on the continental slope implies that the forearc is translating northward at a substantial fraction of the margin-parallel convergence rate.

A new species of Helobdella (Hirudinida: Glossiphoniidae) from Oregon  

USGS Publications Warehouse

Helobdella bowermani n. sp. is described from specimens collected in fine sediment of open water benthos of Upper Klamath Lake, Klamath County, Oregon. The new species has pale yellow/buff coloration with scattered chromatophore blotches throughout the dorsal surface, lateral extensions or papillae only on the a2 annulus, dorsal medial row of papillae with small papilla on a1 and larger papillae on a2 and a3, and a small oval scute (rarely triangular). Helobdella bowermani n. sp. is morphologically similar to Helobdella atli and Helobdella simplex. Molecular comparison of CO-I sequence data from H. bowermani n. sp. revealed differences of 10.6%–10.8% with Helobdella californica, differences of 12.2%–13.7% with H. atli, and differences of 12.7%–13.2% with H. simplex.

SHALLOW HYDROTHERMAL SYSTEM AT NEWBERRY VOLCANO, OREGON: A CONCEPTUAL MODEL.  

USGS Publications Warehouse

Investigations at Newberry Volcano, Oregon, have resulted in a satisfactory account of the shallow hydrothermal system, but have not indicated the nature of a possible geothermal reservoir. Hot springs in the caldera probably represent the return of circulating meteoric water, warmed at shallow depths by high conductive heat flow and by steam rising from greater depths. Ground-water recharge to the hydrothermal system is at most 250 liters per second, of which about 20 liters per second reappears in the hot springs. Analysis of temperature anomalies in a Geological Survey drillhole indicates that ground-water flow totaling about 125 liters per second could be moving laterally at depths of less than 650 m at the drill site.

Pumice deposits of the Klamath Indian Reservation, Klamath County, Oregon  

USGS Publications Warehouse

A large volume of pumice is widely distributed over the Klamath Indian Reservation in 'flow' and 'fall' deposits. The flow material on the Reservation is restricted to the area west of Klamath Marsh, and the fall material is thickest immediately southeast of the Marsh. Tests of the chemical and physical properties of the pumice indicate that the pumice is suitable, with some limitations, for use as an aggregate and as a low-grade abrasive. Preliminary examination also indicates that with proper processing it may have a potential use as pozzuolana. The pumice is similar to material now being marketed for lightweight aggregate in Oregon, but processing of the pumice is necessary to obtain a suitable size distribution of the particles.

Septicemic pasteurellosis in free-ranging neonatal pronghorn in Oregon  

USGS Publications Warehouse

As part of a study to determine the cause(s) of population decline and low survival of pronghorn (Antilocapra americana) neonates on Hart Mountain National Antelope Refuge (HMNAR), Oregon (USA), 55 of 104 neonates captured during May 1996 and 1997 were necropsied (n = 28, 1996; n = 27, 1997) to determine cause of death. Necropsies were conducted on fawns that died during May, June, or July of each year. The objectives of this study were to report the occurrence and pathology of pasteurellosis in neonates and determine if the isolated strain of Pasteurella multocida was unique. Septicemic pasteurellosis, caused by P. multocida, was diagnosed as the cause of death for two neonates in May and June 1997. Necropsy findings included widely scattered petechial and ecchymotic hemorrhages found over a large portion of the subcutaneous tissue, meninges of the brain, epicardium, skeletal muscle, and serosal surface of the thorasic and abdominal cavities. Histological examination of lung tissues revealed diffuse congestion and edema and moderate to marked multifocal infiltrate of macrophages, neutrophils, and numerous bacteria within many terminal bronchioles and alveoli. Pasteurella multocida serotypes A:3,4, and B:1 were isolated from several tissues including lung, intestinal, thorasic fluid, and heart blood. Each B:1 isolate had DNA restriction endonuclease fingerprint profiles distinct from isolates previously characterized from domestic cattle, swan (Olor spp.), moose (Alces alces), and pronghorn from Montana (USA). This is the first report of pasteurellosis in pronghorn from Oregon and the B:1 isolates appear to be unique in comparison to DNA fingerprint profiles from selected domestic and wild species.

Appraisal of storm-water quality near Salem, Oregon  

USGS Publications Warehouse

Stormwater runoff for the period December 1979 to May 1981, at 13 sites (12 basins) in the vicinity of Salem, Oregon, was sampled and analyzed for water quality. Constituent concentrations for urban storm water were relatively small when compared to samples from Portland and Medford, Oregon and to samples from Denver, Colorado. The data indicated that levels of suspended sediment, ultimate CBOD (carbonaceous biochemical oxygen demand), and total lead increased with increased urbanization. Much of the suspended sediment and related turbidity result from transport of basin soils rather than from the wash-off of dry fallout solids from impervious areas. Because of small chemical concentrations and winter high flow and low temperature conditions in the Willamette River, Salem storm water probably has little effect on biological or on most chemical conditions in the Willamette River. An analysis of data from a stormwater detention pond (originally designed to reduce peak flows) indicated that the facility was about 47% efficient in reducing suspended sediment loads. The facility also reduced such sediment-related constituent loads as total lead and total phosphorus. Total Kjeldahl nitrogen and ultimate CBOD loads that are transported mostly in the dissolved phase were not measurably affected by the detention pond. Precipitation samples collected at one site for a year were found to be acidic, with a median pH of 4.6. Median total lead concentration was 8 micrograms/L (ug/L) in precipitation, whereas the median total lead concentration in runoff from the 12 basins ranged from 8 to 110 ug/L. The median dissolved ammonia concentration in precipitation was larger than the median dissolved ammonia concentration at all 13 sites. In contrast, the median total Kjeldahl nitrogen concentration in precipitation samples was about half the median for streamwater concentrations. Median ratios of sulfate to chloride and nitrate to chloride in precipitation were much higher than ratios expected for sea water, suggesting anthropogenic sources for sulfate and nitrate.

Petrology and geochemistry of the Pelican Butte area, S. Oregon  

SciTech Connect

The Cascade mountain range consists of a linear chain of composite volcanoes extending from British Columbia to northern California. The volcanic rocks of the Cascades range in age from Miocene to Holocene. They are believed to result from subduction of the Juan de Fuca plate beneath the North American plate. The area studied is located in the southeastern Oregon Cascades, near Fish Lake, Oregon. Little formal mapping of this area has been done. The purpose of the project was to describe the volcanic units in a seven square mile map area located on the southwestern flank of Pelican Butte. Pelican Butte is a large eruptive center northeast of Mt. McLoughlin. Its summit has been dated at 0.54 Ma + 0.05 Ma. The rocks range in composition from basalts to andesites. Outcrops are generally blocky flows, some of which are associated with pyroclastic material. The overall mineralogy consists of plagioclase feldspar, olivine, [+-] clinopyroxene, [+-] orthopyroxene. In order to investigate genetic relationships between basaltic and andesitic compositions, incompatible elements were plotted on a Cartesian coordinate system. On such a plot, ratios of incompatible elements remain constant among units whose source is the same. A La/Ba plot shows two distinct groups (andesites and basalts) which represent two distinct magmatic sources. The ratios of light REE's, CeN/LaN, however, are within error for all compositions. This suggests a similar mantle source for both basalts and andesites. The increase in Ba in the andesitic compositions may indicate crustal contamination of the mantle source. The trends within compositional groups probably result from crystal fractionation but no fractionation evidence exists between compositional groups.

Shifting the paradigm in Oregon from teen pregnancy prevention to youth sexual health.  

PubMed

Oregon's work on teen pregnancy prevention during the previous 20 years has shifted from a risk-focused paradigm to a youth development model that places young people at the center of their sexual health and well-being. During 2005, the Oregon Governor's Office requested that an ad hoc committee of state agency and private partners develop recommendations for the next phase of teen pregnancy prevention. As a result of that collaborative effort, engagement of young people, and community input, the Oregon Youth Sexual Health Plan was released in 2009. The plan focuses on development of young people and embraces sexuality as a natural part of adolescent development. The plan's five goals and eight objectives guide the work of state agencies and partners addressing youth sexual health. Oregon's development of a statewide plan can serve as a framework for other states and entities to address all aspects of youth sexual health. PMID:23450889

Anticipating Forest and Range Land Development in Central Oregon (USA) for Landscape Analysis, with an Example Application Involving Mule Deer  

NASA Astrophysics Data System (ADS)

Forest policymakers, public lands managers, and scientists in the Pacific Northwest (USA) seek ways to evaluate the landscape-level effects of policies and management through the multidisciplinary development and application of spatially explicit methods and models. The Interagency Mapping and Analysis Project (IMAP) is an ongoing effort to generate landscape-wide vegetation data and models to evaluate the integrated effects of disturbances and management activities on natural resource conditions in Oregon and Washington (USA). In this initial analysis, we characterized the spatial distribution of forest and range land development in a four-county pilot study region in central Oregon. The empirical model describes the spatial distribution of buildings and new building construction as a function of population growth, existing development, topography, land-use zoning, and other factors. We used the model to create geographic information system maps of likely future development based on human population projections to inform complementary landscape analyses underway involving vegetation, habitat, and wildfire interactions. In an example application, we use the model and resulting maps to show the potential impacts of future forest and range land development on mule deer ( Odocoileus hemionus) winter range. Results indicate significant development encroachment and habitat loss already in 2000 with development located along key migration routes and increasing through the projection period to 2040. The example application illustrates a simple way for policymakers and public lands managers to combine existing data and preliminary model outputs to begin to consider the potential effects of development on future landscape conditions.

Stream temperature change detection for state and private forests in the Oregon Coast Range  

NASA Astrophysics Data System (ADS)

Oregon's forested coastal watersheds support important cold-water fisheries of salmon and steelhead (Oncorhynchus spp.) as well as forestry-dependent local economies. Riparian timber harvest restrictions in Oregon and elsewhere are designed to protect stream habitat characteristics while enabling upland timber harvest. We present an assessment of riparian leave tree rule effectiveness at protecting streams from temperature increases in the Oregon Coast Range. We evaluated temperature responses to timber harvest at 33 privately owned and state forest sites with Oregon's water quality temperature antidegradation standard, the Protecting Cold Water (PCW) criterion. At each site we evaluated stream temperature patterns before and after harvest upstream, within, and downstream of harvest units. We developed a method for detecting stream temperature change between years that adhered as closely as possible to Oregon's water quality rule language. The procedure provided an exceedance history across sites that allowed us to quantify background and treatment (timber harvest) PCW exceedance rates. For streams adjacent to harvested areas on privately owned lands, preharvest to postharvest year comparisons exhibited a 40% probability of exceedance. Sites managed according to the more stringent state forest riparian standards did not exhibit exceedance rates that differed from preharvest, control, or downstream rates (5%). These results will inform policy discussion regarding the sufficiency of Oregon's forest practices regulation at protecting stream temperature. The analysis process itself may assist other states and countries in developing and evaluating their forest management and water quality antidegradation regulations.

Probabilistic Tsunami Hazard Assessment: the Seaside, Oregon Pilot Study  

NASA Astrophysics Data System (ADS)

A pilot study of Seaside, Oregon is underway, to develop methodologies for probabilistic tsunami hazard assessments that can be incorporated into Flood Insurance Rate Maps (FIRMs) developed by FEMA's National Flood Insurance Program (NFIP). Current NFIP guidelines for tsunami hazard assessment rely on the science, technology and methodologies developed in the 1970s; although generally regarded as groundbreaking and state-of-the-art for its time, this approach is now superseded by modern methods that reflect substantial advances in tsunami research achieved in the last two decades. In particular, post-1990 technical advances include: improvements in tsunami source specification; improved tsunami inundation models; better computational grids by virtue of improved bathymetric and topographic databases; a larger database of long-term paleoseismic and paleotsunami records and short-term, historical earthquake and tsunami records that can be exploited to develop improved probabilistic methodologies; better understanding of earthquake recurrence and probability models. The NOAA-led U.S. National Tsunami Hazard Mitigation Program (NTHMP), in partnership with FEMA, USGS, NSF and Emergency Management and Geotechnical agencies of the five Pacific States, incorporates these advances into site-specific tsunami hazard assessments for coastal communities in Alaska, California, Hawaii, Oregon and Washington. NTHMP hazard assessment efforts currently focus on developing deterministic, "credible worst-case" scenarios that provide valuable guidance for hazard mitigation and emergency management. The NFIP focus, on the other hand, is on actuarial needs that require probabilistic hazard assessments such as those that characterize 100- and 500-year flooding events. There are clearly overlaps in NFIP and NTHMP objectives. NTHMP worst-case scenario assessments that include an estimated probability of occurrence could benefit the NFIP; NFIP probabilistic assessments of 100- and 500-yr events could benefit the NTHMP. The joint NFIP/NTHMP pilot study at Seaside, Oregon is organized into three closely related components: Probabilistic, Modeling, and Impact studies. Probabilistic studies (Geist, et al., this session) are led by the USGS and include the specification of near- and far-field seismic tsunami sources and their associated probabilities. Modeling studies (Titov, et al., this session) are led by NOAA and include the development and testing of a Seaside tsunami inundation model and an associated database of computed wave height and flow velocity fields. Impact studies (Synolakis, et al., this session) are led by USC and include the computation and analyses of indices for the categorization of hazard zones. The results of each component study will be integrated to produce a Seaside tsunami hazard map. This presentation will provide a brief overview of the project and an update on progress, while the above-referenced companion presentations will provide details on the methods used and the preliminary results obtained by each project component.

Helium Isotope Compositions in Springs From the Three Sisters Region, Central Oregon, USA.  

NASA Astrophysics Data System (ADS)

The Three Sisters region has recently come under increased scrutiny after the discovery by Satellite Radar Interferometry (InSAR) of a broad area of uplift centered approximately 5 km west of the South Sister volcanic edifice (Wicks et al., 2001). The bulge, which at its center reaches a maximum of 10 cm, formed between 1998-2000. The exact cause for the uplift is unknown, but observations from other volcanoes and results from numerical modeling imply that the most likely cause is the movement of magma up to mid-crustal ( ~6.5 km depth) levels (Wicks et al., 2001). The area of uplift coincides with an area where spring chemistry shows anomalously high levels of chloride and carbon emissions (Ingebritsen et al., 1994). These features pre-date the bulge by at least a decade and can also be indicative of a magmatic source. It is unclear if the bulge and the geochemical anomalies are directly related, but both point to the presence of magma below the Three Sisters area. Within the scope of a monitoring project that has recently been initiated to study the development of the bulge and any accompanying changes in the fluid/gas chemistry of springs in the Three Sisters area, 10 gas samples were collected for noble gas analysis in July 2001. Two of these samples were taken from cold bubbling springs located close to the center of the bulge and the remaining 8 were obtained from well documented geothermal springs within the general area of Central Oregon. Helium isotope ratios (reported as Rc/Ra where Rc = air corrected 3He/4Hesample and Ra = 3He/4Heair) for these 8 samples range from 2.8 to 5.1 Ra which is in agreement with existing data reported in a study carried out by Unocal in the early 1980's of geothermal springs in this area. The data show a relationship with distance to the bulge/South Sister volcano: all samples within a radius of ~30 km have helium isotope ratios in the range of 4.5 to 5.1 Ra, while samples that fall outside this radius have distinctly lower helium isotope ratios (<4 Ra). The two samples from the center of the uplift area have helium isotope ratios that are significantly higher (7.4 and 8.6 Ra) than the data for the other springs. This clearly demonstrates the presence of a mantle derived magma at some depth below the bulge and the occurrence of permeable pathways to the surface for gas of magmatic origin. At this time, due to a lack of literature noble gas data for the exact area of the bulge, it cannot be determined if the occurrence of these high ratios, which are a common feature in other Cascade Range volcanoes, coincided with the formation of the bulge or if they predate the uplift. This remains a subject for further study. References: Wicks, C. Jr., Dzurisin, D, Ingebritsen, S. E., Thatcher, W., Lu, Z., and Iversen, J.

Channel change and bed-material transport in the Umpqua River basin, Oregon  

USGS Publications Warehouse

The Umpqua River drains 12,103 square kilometers of western Oregon; with headwaters in the Cascade Range, the river flows through portions of the Klamath Mountains and Oregon Coast Range before entering the Pacific Ocean. Above the head of tide, the Umpqua River, along with its major tributaries, the North and South Umpqua Rivers, flows on a mixed bedrock and alluvium bed, alternating between bedrock rapids and intermittent, shallow gravel bars composed of gravel to cobble-sized clasts. These bars have been a source of commercial aggregate since the mid-twentieth century. Below the head of tide, the Umpqua River contains large bars composed of mud and sand. Motivated by ongoing permitting and aquatic habitat concerns related to in-stream gravel mining on the fluvial reaches, this study evaluated spatial and temporal trends in channel change and bed-material transport for 350 kilometers of river channel along the Umpqua, North Umpqua, and South Umpqua Rivers. The assessment produced (1) detailed mapping of the active channel, using aerial photographs and repeat surveys, and (2) a quantitative estimation of bed-material flux that drew upon detailed measurements of particle size and lithology, equations of transport capacity, and a sediment yield analysis. Bed-material transport capacity estimates at 45 sites throughout the South Umpqua and main stem Umpqua Rivers for the period 1951-2008 result in wide-ranging transport capacity estimates, reflecting the difficulty of applying equations of bed-material transport to a supply-limited river. Median transport capacity values calculated from surface-based equations of bedload transport for each of the study reaches provide indications of maximum possible transport rates and range from 8,000 to 27,000 metric tons per year (tons/yr) for the South Umpqua River and 20,000 to 82,000 metric tons/yr for the main stem Umpqua River upstream of the head of tide; the North Umpqua River probably contributes little bed material. A plausible range of average annual transport rates for the South and main stem Umpqua Rivers, based on bedload transport capacity estimates for bars with reasonable values for reference shear stress, is between 500 and 20,000 metric tons/yr. An empirical bed-material yield analysis predicts 20,000-50,000 metric tons/yr on the South Umpqua River and main stem Umpqua River through the Oregon Coast Range, decreasing to approximately 30,000 metric tons/yr at the head of tide. Surveys of individual mining sites in the South Umpqua River indicate minimum local bed-material flux rates that are typically less than 10,000 metric tons/yr but range up to 30,600 metric tons/yr in high-flow years. On the basis of all of these analyses, actual bedload flux in most years is probably less than 25,000 metric tons/yr in the South Umpqua and main stem Umpqua Rivers, with the North Umpqua River probably contributing negligible amounts. For comparison, the estimated annual volume of commercial gravel extraction from the South Umpqua River between 2001 and 2004 ranged from 610 to 36,570 metric tons, indicating that historical in-stream gravel extraction may have been a substantial fraction of the overall bedload flux.

Petrologic, tectonic, and metallogenic evolution of the Ancestral Cascades magmatic arc, Washington, Oregon, and northern California  

USGS Publications Warehouse

Present-day High Cascades arc magmatism was preceded by ~40 m.y. of nearly cospatial magmatism represented by the ancestral Cascades arc in Washington, Oregon, and northernmost California (United States). Time-space-composition relations for the ancestral Cascades arc have been synthesized from a recent compilation of more than 4000 geochemical analyses and associated age data. Neither the composition nor distribution of ancestral Cascades magmatism was uniform along the length of the ancestral arc through time. Initial (>40 to 36 Ma) ancestral Cascades magmatism (mostly basalt and basaltic andesite) was focused at the north end of the arc between the present-day locations of Mount Rainier and the Columbia River. From 35 to 18 Ma, initial basaltic andesite and andesite magmatism evolved to include dacite and rhyolite; magmatic activity became more voluminous and extended along most of the arc. Between 17 and 8 Ma, magmatism was focused along the part of the arc coincident with the northern two-thirds of Oregon and returned to more mafic compositions. Subsequent ancestral Cascades magmatism was dominated by basaltic andesite to basalt prior to the post–4 Ma onset of High Cascades magmatism. Transitional tholeiitic to calc-alkaline compositions dominated early (before 40 to ca. 25 Ma) ancestral Cascades eruptive products, whereas the majority of the younger arc rocks have a calc-alkaline affinity. Tholeiitic compositions characteristic of the oldest ancestral arc magmas suggest development associated with thin, immature crust and slab window processes, whereas the younger, calc-alkaline magmas suggest interaction with thicker, more evolved crust and more conventional subduction-related magmatic processes. Presumed changes in subducted slab dip through time also correlate with fundamental magma composition variation. The predominance of mafic compositions during latest ancestral arc magmatism and throughout the history of modern High Cascades magmatism probably reflects extensional tectonics that dominated during these periods of arc magmatism. Mineral deposits associated with ancestral Cascades arc rocks are uncommon; most are small and low grade relative to those found in other continental magmatic arcs. The small size, low grade, and dearth of deposits, especially in the southern two-thirds of the ancestral arc, probably reflect many factors, the most important of which may be the prevalence of extensional tectonics within this arc domain during this magmatic episode. Progressive clockwise rotation of the forearc block west of the evolving Oregon part of the ancestral Cascades magmatism produced an extensional regime that did not foster significant mineral deposit formation. In contrast, the Washington arc domain developed in a transpressional to mildly compressive regime that was more conducive to magmatic processes and hydrothermal fluid channeling critical to deposit formation. Small, low-grade porphyry copper deposits in the northern third of the ancestral Cascades arc segment also may be a consequence of more mature continental crust, including a Mesozoic component, beneath Washington north of Mount St. Helens.

Development of an Environmental Flow Framework for the McKenzie River Basin, Oregon  

USGS Publications Warehouse

The McKenzie River is a tributary to the Willamette River in northwestern Oregon. The McKenzie River is approximately 90 miles in length and has a drainage area of approximately 1,300 square miles. Two major flood control dams, a hydropower dam complex, and two hydropower canals significantly alter streamflows in the river. The structures reduce the magnitude and frequency of large and small floods while increasing the annual 7-day minimum streamflows. Stream temperatures also have been altered by the dams and other anthropogenic factors, such as the removal of riparian vegetation and channel simplification. Flow releases from one of the flood control dams are cooler in the summer and warmer in the fall in comparison to unregulated flow conditions before the dam was constructed. In 2006, the Oregon Department of Environmental Quality listed a total of 112.4, 6.3, and 55.7 miles of the McKenzie River basin mainstem and tributary stream reaches as thermally impaired for salmonid rearing, salmonid spawning, and bull trout, respectively. The analyses in this report, along with previous studies, indicate that dams have altered downstream channel morphology and ecologic communities. In addition to reducing the magnitude and frequency of floods, dams have diminished sediment transport by trapping bed material. Other anthropogenic factors, such as bank stabilization, highway construction, and reductions of in-channel wood, also have contributed to the loss of riparian habitat. A comparison of aerial photography taken in 1939 and 2005 showed substantial decreases in secondary channels, gravel bars, and channel sinuosity, particularly along the lower alluvial reaches of the McKenzie River. In addition, bed armoring and incision may contribute to habitat degradation, although further study is needed to determine the extent of these processes. Peak streamflow reduction has led to vegetation colonization and stabilization of formerly active bar surfaces. The large flood control dams on Blue River and South Fork McKenzie River likely have had the greatest effect on downstream habitats because these sediment and flood-rich tributaries historically contributed a disproportionate volume of bed material, wood, and peak flows in comparison with the spring-fed tributaries of the upper McKenzie River basin. The ecological effects of the dams were examined by focusing on nine exemplar aquatic and terrestrial species, including spring Chinook salmon, bull trout, Oregon chub, Pacific and western brook lamprey, red-legged frog, western pond turtle, alder, and cottonwood. The changes caused by the dams to streamflow hydrograph affect all these and other species in complex ways, although a few commonalities are apparent. A loss of channel complexity in the McKenzie River basin, which is associated with the reduction in flood events and widespread channel stabilization, is the primary factor related to the observed population declines for all nine exemplar species. The dams also have caused direct ecological effects by blocking access to habitat, changing the amount and timing of available critical habitat, and changing water temperature during important seasons for different life stages.

Selective Cutting Impact on Carbon Storage in Fremont-Winema National Forest, Oregon  

NASA Astrophysics Data System (ADS)

Management personnel of the Fremont-Winema National Forest in southern Oregon were interested in investigating how selective cutting or fuel load reduction treatments affect forest carbon sinks and as an ancillary product, fire risk. This study was constructed with the objective of providing this information to the forest administrators, as well as to satisfy a directive to study carbon management, a component of the 2004 NASA's Application Division Program Plan. During the summer of 2004, a request for decision support tools by the forest management was addressed by a NASA sponsored student-led, student-run internship group called DEVELOP. This full-time10-week program was designed to be an introduction to work done by earth scientists, professional business / client relationships and the facilities available at NASA Ames. Four college and graduate students from varying educational backgrounds designed the study and implementation plan. The team collected data for five consecutive days in Oregon throughout the Fremont-Winema forest and the surrounding terrain, consisting of soil sampling for underground carbon dynamics, fire model and vegetation map validation. The goal of the carbon management component of the project was to model current carbon levels, then to gauge the effect of fuel load reduction treatments. To study carbon dynamics, MODIS derived fraction photosynthetically active radiation (FPAR) maps, regional climate data, and Landsat 5 generated dominant vegetation species and land cover maps were used in conjunction with the NASA - Carnegie-Ames-Stanford-Approach (CASA) model. To address fire risk the dominant vegetation species map was used to estimate fuel load based on species biomass in conjunction with a mosaic of digital elevation models (DEMs) as components to the creation of an Anderson-inspired fuel map, a rate of spread in meters/minute map and a flame length map using ArcMap 9 and FlamMap. Fire risk results are to be viewed qualitatively as maps output spatial distribution of data rather then quantitative assessment of risk. For the first time ever, the resource managers at the Fremont-Winema forest will be taking into consideration the value of carbon as a resource in their decision making process for the 2005 Fremont-Winema forest management plan.

Tsunami Hazard Assessment of the Northern Oregon Coast: A Multi-Deterministic Approach Tested at Cannon Beach, Oregon  

NASA Astrophysics Data System (ADS)

To update the tsunami hazard assessment method for Oregon, we (1) evaluate geologically reasonable variability of the earthquake rupture process on the Cascadia megathrust, (2) compare those scenarios to geological and geophysical evidence for plate locking, (3) specify 25 deterministic earthquake sources, and (4) use the resulting vertical coseismic deformations as initial conditions for simulation of Cascadia tsunami inundation at Cannon Beach, Oregon. Because of the Cannon Beach focus, the north-south extent of source scenarios is limited to Neah Bay, Washington to Florence, Oregon. We use the marine paleoseismic record to establish recurrence bins from the 10,000 year event record and select representative coseismic slips from these data. Assumed slips on the megathrust are 8.4 m (290 yrs of convergence), 15.2 m (525 years of convergence), 21.6 m (748 years of convergence), and 37.5 m (1298 years of convergence) which, if the sources were extended to the entire Cascadia margin, give Mw varying from approximately 8.3 to 9.3. Additional parameters explored by these scenarios characterize ruptures with a buried megathrust versus splay faulting, local versus regional slip patches, and seaward skewed versus symmetrical slip distribution. By assigning variable weights to the 25 source scenarios using a logic tree approach, we derived percentile inundation lines that express the confidence level (percentage) that a Cascadia tsunami will NOT exceed the line. Lines of 50, 70, 90, and 99 percent confidence correspond to maximum runup of 8.9, 10.5, 13.2, and 28.4 m (NAVD88). The tsunami source with highest logic tree weight (preferred scenario) involved rupture of a splay fault with 15.2 m slip that produced tsunami inundation near the 70 percent confidence line. Minimum inundation consistent with the inland extent of three Cascadia tsunami sand layers deposited east of Cannon Beach within the last 1000 years suggests a minimum of 15.2 m slip on buried megathrust ruptures. The largest tsunami run-up at the 99 percent isoline was from 37.5 m slip partitioned to a splay fault. This type of extreme event is considered to be very rare, perhaps once in 10,000 years based on offshore paleoseismic evidence, but it can produce waves rivaling the 2004 Indian Ocean tsunami. Cascadia coseismic deformation most similar to the Indian Ocean earthquake produced generally smaller tsunamis than at the Indian Ocean due mostly to the 1 km shallower water depth on the Cascadia margin. Inundation from distant tsunami sources was assessed by simulation of only two Mw 9.2 earthquakes in the Gulf of Alaska, a hypothetical worst-case developed by the Tsunami Pilot Study Working Group (2006) and a historical worst case, the 1964 Prince William Sound Earthquake; maximum runups were, respectively, 12.4 m and 7.5 m.

Algal conditions and the potential for future algal problems in the Willamette River, Oregon  

USGS Publications Warehouse

For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

Sedimentary record of subduction to forearc transition in the rotated Eocene basin of western Oregon  

NASA Astrophysics Data System (ADS)

Systematic changes in compositions of Eocene sandstones in the southern part of the Oregon Coast Range constrain proposed models of tectonic accretion and rotation of this crustal fragment. Three basic petrofacies of lithic, arkosic, and volcanolithic composition can be defined sequentially from the base to the top of the section. The lithic petrofacies was deposited prior to rotation and was derived from the nearby Klamath Mountains during collision of the subjacent seamount terrane. The transition to arkosic composition coincided with the end of collision and the initiation of forearc basin subsidence. The arkosic sands contain muscovite and potassium feldspar derived from a continental-plutonic source area; their presence in the forearc sequence suggests that the Coast Range block lay farther to the east and closer to interior parts of the Mesozoic batholith belt prior to tectonic rotation. Volcanolithic sandstones were deposited after rotation of the Coast Range had begun, and they mark the beginning of volcanic activity in the adjacent Cascade arc. *Present address (after August 1, 1983): Department of Geology, University of Wyoming, Laramie, Wyoming 82070

Bonneville Power Administration is the funding source for the Oregon Department of Fish and Wildlife`s Annual Coded Wire Tag Program - Oregon Missing Production Groups Project. Tule brood fall chinook were caught primarily in the British Columbia, Washington and northern Oregon ocean commercial fisheries. The up-river bright fall chinook contributed primarily to the Alaska and British Columbia ocean commercial fisheries and the Columbia River gillnet fishery. Contribution of Rogue fall chinook released in the lower Columbia River system occurred primarily in the Oregon ocean commercial and Columbia river gillnet fisheries Willamette spring chinook salmon contributed primarily to the Alaska and British Columbia ocean commercial, Oregon freshwater sport and Columbia River gillnet fisheries. Restricted ocean sport and commercial fisheries limited contribution of the Columbia coho released in the Umatilla River that survived at an average rate of 1.05% and contributed primarily to the Washington, Oregon and California ocean sport and commercial fisheries and the Columbia River gillnet fishery. The 1987 to 1991 brood years of coho released in the Yakima River survived at an average rate of 0.64% and contributed primarily to the Washington, Oregon and California ocean sport and commercial fisheries and the Columbia River gillnet fishery. Survival rates of salmon and steelhead are influenced, not only by factors in the hatchery, disease, density, diet and size and time of release, but also by environmental factors in the river and ocean. These environmental factors are controlled by large scale weather patterns such as El Nino over which man has no influence. Man could have some influence over river flow conditions, but political and economic pressures generally out weigh the biological needs of the fish.

Potential hydrologic effects of developing coal and other geoenergy resources in Oregon: a review  

SciTech Connect

Geoenergy resources in Oregon, in addition to coal, include noncommercial deposits of oil shale, natural gas, and geothermal heat. Commercial quantities of natural gas were discovered at Mist in northwestern Oregon in 1979. Gas presently is being produced from five wells and additional exploratory drilling is underway. More than 2 million acres of Oregon land is under lease for petroleum and natural gas exploration, mostly in the Astoria embayment-Willamette syncline, central (Oregon) Paleozoic-Mesozoic basin, and eastern Tertiary nonmarine basin. The Cascade Range and eastern Oregon contain sizable resources of geothermal heat, of which a small part has been developed for space heating at Klamath Falls and Lakeview. Thirteen Known Geothermal Resource Areas (KGRA's) comprising 432,000 acres have been identified, 422,000 acres are currently leased for geothermal development. KGRA's judged to have potential for generation of electrical power are Newberry Crater, Crump Geyser, and Alvord Desert. No adverse hydrologic effects have been noted to date from coal or other geoenergy exploration or development in Oregon, and no effects are expected if federal and state regulations are adhered to. The southwestern Oregon coals would have to be mined by underground methods. Potential hydrologic impacts would be local increases in sedimentation, turbidity, and mineralization of surface and ground water. Water-quality degradation, including both thermal pollution and increased concentrations of dissolved minerals, could result from geothermal development. Other potential problems include land subsidence and consumptive use of water associated with both coal and geothermal development. 53 refs., 3 figs., 1 tab.

Geothermal hydrology of Warner Valley, Oregon: a reconnaissance study  

SciTech Connect

Warner Valley and its southern extension, Coleman Valley, are two of several high-desert valleys in the Basin and Range province of south-central Oregon that contain thermal waters. At least 20 thermal springs, defined as having temperatures of 20/sup 0/C or more, issue from Tertiary basaltic flows and tuffs in and near the valleys. Many shallow wells also produce thermal waters. The highest measured temperature is 127/sup 0/C, reported from a well known as Crump geyser, at a depth of 200 meters. The hottest spring, located near Crump geyser, has a surface temperature of 78/sup 0/C. The occurrence of these thermal waters is closely related to faults and fault intersections in the graben and horst structure of the valleys. Chemical analyses show that the thermal waters are of two types: sodium chloride and sodium bicarbonate waters. Chemical indicators show that the geothermal system is a hot-water rather than a vapor-dominated system. Conductive heat flow in areas of the valley unaffected by hydrothermal convection is probably about 75 milliwatts per square meter. The normal thermal gradient in valley-fill dpeosits in these areas may be about 40/sup 0/C per kilometer. Geothermometers and mixing models indicate that temperatures of equilibration are at least 170/sup 0/C for the thermal components of the hotter waters. The size and location of geothermal reservoirs are unknown.

Petrology of monogenetic volcanoes, Mount Bailey area, Cascade Range, Oregon  

NASA Astrophysics Data System (ADS)

The Mt. Bailey area encompasses the contact between Western Cascade and High Cascade volcanic rocks in southern Oregon. Western Cascade rocks are represented by a thick stack of magnetically reversed lavas and intercalated laharic deposits (the “Devils Canyon sequence”) that range in composition from calc-alkaline basalt to andesite. The oldest (magnetically reversed) rocks of the High Cascade sequence formed two small andesitic shield volcanoes and, in the northern part of the area, several intracanyon flows of high-alumina olivine tholeiite (HAOT). These eruptions were followed by formation of a basaltic shield volcano (Sherwood Butte) and then by the eruption of andesitic lavas to form Mt. Bailey, and basaltic andesite which formed the adjacent cone of Garwood Butte. The Devils Canyon lavas are enriched in total Fe, total alkalis, K2O, P2O5, and TiO2 relative to the High Cascade lavas. High Cascade lavas display calc-alkaline affinities (e.g., enrichment of large-ion lithophile element and light rare earth elements) except for the intracanyon HAOT, which has trace-element characteristics typical of MORB. Rb/Zr ratios suggest that calc-alkaline lavas from each of the High Cascade volcanoes represent distinct episodes of partial melting. The source of the calc-alkaline magmas was probably mantle enriched by fluids derived from subducted oceanic crust, whereas the source of the HOAT was depleted mantle similar to the source of MORB.

District heating system, College Industrial Park, Klamath Falls, Oregon  

SciTech Connect

The College Industrial Park (CIP) is located to the northwest of the Oregon Institute of Technology (OIT) campus. Waste water from the OIT campus geothermal heating system flows through an open ditch to the south of the Park. Being aware of this, city personnel have requested the Geo-Heat Center design a distribution network for the Park to eventually utilize an estimated 600 GPM of the 130/sup 0/F waste water. Geothermal water from each campus building is discharged into storm drains which also collect surface run off from parking lots, roofs and grounds. Waste water temperatures are generally between 120/sup 0/F and 130/sup 0/F, however, it may drop as low as 90/sup 0/F when mixing occurs with large amounts of surface run off. Peak heating load requirements for the OIT campus are estimated to be 17.8 x 10/sup 6/ Btu/hour for 567,000 square feet of space. Peak flow rate of geothermal fluid to satisfy this load is then 593 GPM based on a net 60/sup 0/F temperature differential. Three wells are available to supply the necessary flow. A Lithium-Bromide Absorption Chiller (185 ton) was installed in 1980 to provide space cooling. The chiller requires a constant flow rate of 550 GPM and discharges 170/sup 0/F water to the storm drains during summer months.

Fogwater chemistry in a wood-burning community, western Oregon  

SciTech Connect

Fogwater chemistry in Corvallis, Oregon, a wood-burning community (pop. approximately 43,000) was compared with the chemistry of fogwater collected in more remote and in more highly industrialized areas. The fogwater was not acidic (median pH = 5.7) and was usually dominated by SO4=, NO3-, and NH4+ whose concentrations were generally lower than in fogwater in other urban areas but higher than in remote areas. Concentrations of formic and acetic acids (medians = 61 and 52 microN, respectively) were comparable to those in fogwater in Los Angeles, California and were typically much higher than concentrations in fogwater from more remote areas. Formate and acetate concentrations were often comparable to those of SO4= and NO3-. Formaldehyde concentrations (range = 0.4-3.0 mg L-1) were comparable to those in fogwater in some urban areas of southern California, yet lower than concentrations in highly industrialized areas of southern California. Because concentrations of organic compounds in Corvallis fogwater were often comparable to those in larger urban areas, sources in addition to motor vehicles must be important in Corvallis. Additional sources may be natural and anthropogenic, the latter including residential wood burning and wood products industries.

Geothermal aquaculture project: Real Property Systems Inc. , Harney Basin, Oregon  

SciTech Connect

Real Property Systems Inc., (RPS) owns two parcels in the vicinity of Harney Lake, Oregon. One parcel is 120 acres in size, the other is 200 acres. A study concludes that the 200 acre parcel has the greater potential for geothermal development. RPS is interested in an aquaculture operation that produces fresh water prawns, (Macrobrachium rosenbergii) for the market. To supply the heat necessary to maintain the ideal temperature of 82/sup 0/F desired for these prawns, a geothermal resource having a 150/sup 0/F temperature or higher, is needed. The best estimate is that 150/sup 0/F water can be found from a minimum 1090 feet depth to 2625 feet, with no absolute assurances that sufficient quantities of geothermal waters exist without drilling for the same. This study undertakes the preliminary determination of project economics so that a decision can be made whether or not to proceed with exploratory drilling. The study is based on 10 acres of ponds, with a peak requirement of 2500 gpm of 150/sup 0/F geothermal water.

Characterization of Leuconostoc oenos Isolated from Oregon Wines †  

PubMed Central

This study was designed to characterize isolates of Leuconostoc species from Oregon wines. Gram-positive cocci were isolated, and their biochemical properties and abilities to decompose malic acid were determined. All of the isolates were heterofermentative, catalase negative, and facultatively anaerobic and occurred in pairs and chains. They produced acid from glucose, fructose, mannose, ribose, cellobiose, trehalose, and salicin but not from sucrose or lactose. They did not produce ammonia from arginine or dextran from sucrose. They grew at pH values of less than 4 and in 10% ethanol. Most but not all strains produced lactic acid and carbon dioxide from malic acid, as determined by paper chromatography and respirometry, respectively. These malolactic bacteria were considered to be strains of Leuconostoc oenos. We compared these isolates with reference strains for relative growth at pH values of 4.0, 3.5, 3.0, and 2.8 at 22°C. The isolates were similar in their growth responses at the two highest pH levels. At pH 3.0 and 2.8, however, the strains failed to grow but revealed variable abilities to dissimilate malic acid.

Geomorphic surfaces in the northwestern Klamath Mountains, California and Oregon  

SciTech Connect

Thick, residual, colluvial and alluvial soils derived from ophiolitic rocks mantle at least four geomorphic surfaces in the Siskiyou and marble mountains, in northwestern California and Illinois Valley, in southwestern Oregon. Analysis of digital elevation data provides constraints on the distribution and origin of these surfaces. Because of the geomorphic expression and soil mechanical properties of the surfaces, a map of slope gradients less than 22 degrees closely approximates the distribution of geomorphic surfaces as they are known from field observations. Preliminary definition of individual surfaces is based upon classification of the slop-map by elevation ranges. The Klamath Peneplain'' of Diller (1902) and associated soils, recently referred to as Klamath Saprolite'', are recognized near summit elevation (1,500 meters) across the area. Regional uplift and erosion has resulted in extensive, large earthflow landslides derived from these soils. Alluvial and residual deposits on the floor of the Illinois Valley occur at the same elevation (300 meters) as incised alluvial and colluvial terrace deposits along the Klamath River and tributary streams. At least two additional surfaces have been identified in the Siskiyou and Marble Mountains at approximately elevation 750 and 1,000 meters. Analysis of digital elevation data, combined with the map of earthflow landslides, allows rapid preliminary mapping of geomorphic surfaces in this terrain.

Ultraviolet radiation and bio-optics in Crater Lake, Oregon  

USGS Publications Warehouse

Crater Lake, Oregon, is a mid-latitude caldera lake famous for its depth (594 m) and blue color. Recent underwater spectral measurements of solar radiation (300-800 nm) support earlier observations of unusual transparency and extend these to UV-B wavelengths. New data suggest that penetration of solar UVR into Crater Lake has a significant ecological impact. Evidence includes a correlation between water column chlorophyll-a and stratospheric ozone since 1984, the scarcity of organisms in the upper water column, and apparent UV screening pigments in phytoplankton that vary with depth. The lowest UV-B diffuse attenuation coefficients (K d,320) were similar to those reported for the clearest natural waters elsewhere, and were lower than estimates for pure water published in 1981. Optical proxies for UVR attenuation were correlated with chlorophyll-a concentration (0-30 m) during typical dry summer months from 1984 to 2002. Using all proxies and measurements of UV transparency, decadal and longer cycles were apparent but no long-term trend since the first optical measurement in 1896. ?? 2007 Springer Science+Business Media B.V.

Evaluation of city well 1, Klamath Falls, Oregon  

SciTech Connect

A city-wide geothermal space heating project is currently under development at Klamath Falls, Oregon. The first phase of the project will require two production wells. Geothermally heated water will be used to heat 14 city, county, state, and federal buildings. At peak load the heating system will require approximately 750 gpm of 200{sup 0}F (or greater) geothermal brine. The first production well was spudded on August 29, 1979. During drilling a major lost circulation zone was encountered between 340 and 360 ft depth. At this time the well was cleaned, reamed, cased to 300 ft, and then pump tested. The well was pumped for a total of 15 1/2 hr. A maximum flow rate of 680, with 77 ft of drawdown, was held constant for 7 1/2 hr. Discharge temperature was approximately 218{sup 0}F. Three observation wells were monitored to determine the impact of producing large quantities of brine on the many private geothermal wells already in use for space heating. Preliminary indications are that the water level decline in the area will be small (2 to 3 ft). However, further testing is recommended to determine the effects of reservoir heterogeneity on the water level decline.

Sampling considerations for garden symphylans (Order: Cephalostigmata) in western Oregon.  

PubMed

Sampling recommendations were developed for a potato bait sampling method used to estimate garden symphylan (Scutigerella immaculata Newport) densities in western Oregon. Sample size requirements were developed using Taylor's power law to describe the relationship between sample means and variances. Developed sampling recommendations performed well at sample sizes of 30 and greater, when validated by resampling a cohort of 40 independent data sets. Sample size requirements for the bait sampling method were 1.5 times greater than the requirements for the soil sampling method over densities from 1 to 20 S. immaculata per sample unit. As S. immaculata densities increased from April to May, sample size requirements decreased by 36% for fixed precision levels. For sampling in April, decreasing the damage threshold from 20, to 10 and five S. immaculata per sample unit, required a 1.6 and 2.5 times greater sample size requirement, respectively, for a fixed precision level (c) appropriate for pest management (c = 0.25). The bait sampling method provides an efficient reliable alternative to the standard soil sampling method used to monitor garden symphylan populations. PMID:12852643

Feasibility analysis of geothermal district heating for Lakeview, Oregon  

SciTech Connect

An analysis of the geothermal resource at Lakeview, Oregon, indicates that a substantial resource exists in the area capable of supporting extensive residential, commercial and industrial heat loads. Good resource productivity is expected with water temperatures of 200{degrees}F at depths of 600 to 3000 feet in the immediate vicinity of the town. Preliminary district heating system designs were developed for a Base Case serving 1170 homes, 119 commercial and municipal buildings, and a new alcohol fuel production facility; a second design was prepared for a downtown Mini-district case with 50 commercial users and the alcohol plant. Capital and operating costs were determined for both cases. Initial development of the Lakeview system has involved conducting user surveys, well tests, determinations of institutional requirements, system designs, and project feasibility analyses. A preferred approach for development will be to establish the downtown Mini-district and, as experience and acceptance are obtained, to expand the system to other areas of town. Projected energy costs for the Mini-district are $10.30 per million Btu while those for the larger Base Case design are $8.20 per million Btu. These costs are competitive with costs for existing sources of energy in the Lakeview area.

Spatial Digital Database for the Geologic Map of Oregon  

USGS Publications Warehouse

Introduction This report describes and makes available a geologic digital spatial database (orgeo) representing the geologic map of Oregon (Walker and MacLeod, 1991). The original paper publication was printed as a single map sheet at a scale of 1:500,000, accompanied by a second sheet containing map unit descriptions and ancillary data. A digital version of the Walker and MacLeod (1991) map was included in Raines and others (1996). The dataset provided by this open-file report supersedes the earlier published digital version (Raines and others, 1996). This digital spatial database is one of many being created by the U.S. Geological Survey as an ongoing effort to provide geologic information for use in spatial analysis in a geographic information system (GIS). This database can be queried in many ways to produce a variety of geologic maps. This database is not meant to be used or displayed at any scale larger than 1:500,000 (for example, 1:100,000). This report describes the methods used to convert the geologic map data into a digital format, describes the ArcInfo GIS file structures and relationships, and explains how to download the digital files from the U.S. Geological Survey public access World Wide Web site on the Internet. Scanned images of the printed map (Walker and MacLeod, 1991), their correlation of map units, and their explanation of map symbols are also available for download.

Economic Impacts of Geothermal Development in Harney County, Oregon.  

SciTech Connect

This study provides local economic impact estimates for a 100 megawatt (MW) geothermal power project in Oregon. The hypothetical project would be in Harney Count. Bonneville Power Administration commissioned this study to quantify such impacts as part of regional confirmation work recommended by the Northwest Power Planning Council and its advisors. Harney County was chosen as it has both identified resources and industry interest. Geothermal energy is defined as the heat of the earth. For purposes of this study, geothermal energy is heat capable of economically generating electricity (using available technology). That translates to steam or hot water over 300{degrees}F. Local economic impacts include direct, indirect, and induced changes in the local economy. Direct economic impacts result from the costs of plant development, construction, and operation. Indirect impacts result from household and local government purchases. Induced impacts result from continued respending as goods and services to support the households and local governments are purchased. Employment impacts of geothermal development follow a pattern similar to the economic impacts. The workers associated with plant development bring their families to the area. Additional labor is required to provide support services for the new population. Local government services must also increase to support the new community growth and the geothermal plant itself. These changes yield indirect and induced employment impacts associated with the geothermal plant.

Oregon's guidelines for physician-assisted suicide: a legal and ethical analysis.  

PubMed

Oregon's Death with Dignity Act was first passed by a ballot initiative in 1994, but numerous judicial challenges delayed implementation of the Act. In November of 1997, following the United States Supreme Court decisions in Vacco v. Quill and Washington v. Glucksberg, which left the states' power to regulate physician-assisted suicide undisturbed, the Oregon voters upheld their law. Oregon remains the only state in the nation to authorize physician-assisted suicide. The Task Force to Improve the Care of Terminally Ill Oregonians published a Guidebook for health care providers on the Oregon Act, and the New England Journal of Medicine recently issued a special report on the first year's experience under the Act. This paper analyzes the legal context of the Oregon Death with Dignity Act, discusses the efficacy of the tenets in the Guidebook, and explores ethical issues underlying the guidelines, particularly those pertaining to the meaning of a patient's request for assisted suicide and processes supporting informed consent.

Ground-Water Hydrology of the Upper Deschutes Basin, Oregon  

USGS Publications Warehouse

The upper Deschutes Basin is among the fastest growing regions in Oregon. The rapid population growth has been accompanied by increased demand for water. Surface streams, however, have been administratively closed to additional appropriation for many years, and surface water is not generally available to support new development. Consequently, ground water is being relied upon to satisfy the growth in water demand. Oregon water law requires that the potential effects of ground-water development on streamflow be evaluated when considering applications for new ground-water rights. Prior to this study, hydrologic understanding has been insufficient to quantitatively evaluate the connection between ground water and streamflow, and the behavior of the regional ground-water flow system in general. This report describes the results of a hydrologic investigation undertaken to provide that understanding. The investigation encompasses about 4,500 square miles of the upper Deschutes River drainage basin.A large proportion of the precipitation in the upper Deschutes Basin falls in the Cascade Range, making it the principal ground-water recharge area for the basin. Water-balance calculations indicate that the average annual rate of ground- water recharge from precipitation is about 3,500 ft3/s (cubic feet per second). Water-budget calculations indicate that in addition to recharge from precipitation, water enters the ground-water system through interbasin flow. Approximately 800 ft3/s flows into the Metolius River drainage from the west and about 50 ft3/s flows into the southeastern part of the study area from the Fort Rock Basin. East of the Cascade Range, there is little or no ground-water recharge from precipitation, but leaking irrigation canals are a significant source of artificial recharge north of Bend. The average annual rate of canal leakage during 1994 was estimated to be about 490 ft3/s. Ground water flows from the Cascade Range through permeable volcanic rocks eastward out into the basin and then generally northward. About one-half the ground water flowing from the Cascade Range discharges to spring-fed streams along the margins of the range, including the upper Metolius River and its tributaries. The remaining ground water flows through the subsurface, primarily through rocks of the Deschutes Formation, and eventually discharges to streams near the confluence of the Deschutes, Crooked, and Metolius Rivers. Substantial ground-water discharge occurs along the lower 2 miles of Squaw Creek, the Deschutes River between Lower Bridge and Pelton Dam, the lower Crooked River between Osborne Canyon and the mouth, and in Lake Billy Chinook (a reservoir that inundates the confluence of the Deschutes, Crooked, and Metolius Rivers).The large amount of ground-water discharge in the confluence area is primarily caused by geologic factors. North (downstream) of the confluence area, the upper Deschutes Basin is transected by a broad region of low-permeability rock of the John Day Formation. The Deschutes River flows north across the low-permeability region, but the permeable Deschutes Formation, through which most of the regional ground water flows, ends against this rampart of low-permeability rock. The northward-flowing ground water discharges to the streams in this area because the permeable strata through which it flows terminate, forcing the water to discharge to the surface. Virtually all of the regional ground water in the upper Deschutes Basin discharges to surface streams south of the area where the Deschutes River enters this low-permeability terrane, at roughly the location of Pelton Dam.The effects of ground-water withdrawal on streamflow cannot presently be measured because of measurement error and the large amount of natural variability in ground-water discharge. The summer streamflow near Madras, which is made up largely of ground-water discharge, is approximately 4,000 ft3/s. Estimated consumptive ground-water use in the basin i

Epizootiology of Sarcocystis infections in mule deer fawns in Oregon.  

PubMed

From 1974 to 1977, 62 wild mule deer (Odocoileus hemionus) fawns from Steens Mountain, Ore were euthanatized in autumn (23 deer), winter (21 deer), and spring (18 deer). The number of sarcocysts of Sarcocystis spp was counted in histologic sections of various muscular organs. Sarcocysts were seen in the muscle specimens of 14 of the 23 deer euthanatized in autumn (September to November) and in specimens from all 39 deer euthanatized in winter (December and January) and spring (March and April). The sarcocyst burden was greatest in the spring (736/deer), less in the winter (150/deer), and least in autumn (12/deer). Most sarcocysts collected from 3- to 5-month-old deer in autumn were immature, whereas most sarcocysts collected from 9- and 10-month-old deer in the spring were mature. More sarcocysts were seen in sections of muscles from limbs than in those of tongue, esophagus, and other skeletal muscles; the fewest sarcocysts were seen in the heart. Degenerating sarcocysts were seen in deer examined in the spring, but not in deer examined in autumn and winter. Sarcocystis was the only infectious agent found in unthrifty deer fawns. Of the 18 fawns (6 in autumn, 1974; 6 in winter, 1974; and 6 in spring, 1975) examined for helminths, only mild infections were seen in the deer examined in the spring of 1975. From 1974 to 1977, from the Crooked Creek area of Oregon, 48 mule deer fawns (12 in autumn, 18 in winter, and 18 in spring) were euthanatized and evaluated for Sarcocystis infections.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3935614

Radiological survey of the Albany Research Center, Albany, Oregon  

SciTech Connect

In early 1984, a radiological survey was conducted at the Albany Research Center (ARC) in Albany, Oregon. The survey was performed as part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), a US Department of Energy effort to identify, clean up, or otherwise control sites where low level radioactive contamination (exceeding current guidelines) remains from the early years of the Nation's atomic energy program. From 1978 through 1982, the Argonne National Laboratory conducted radiological surveys of the ARC and identified areas with radiological readings above background. The 1984 survey was necessary to determine actual levels of contamination in each area and to define the locations and boundaries of above-guideline contamination. The 1984 survey revealed site field areas with above-guideline concentrations of /sup 232/Th and /sup 226/Ra in surface and subsurface soils. Using the 1984 survey findings for surface area and depths of contamination, and based on current cleanup guidelines for /sup 232/Th and /sup 226/Ra, about 2000 m/sup 3/ of contaminated material would require removal for the ARC site to comply with guidelines. Cleanup of approximately 5 m/sup 3/ of above-guideline contamination in two sumps, one drain, and associated piping also would be required. In addition, nine site buildings contained scattered above-guideline contamination on floors and/or walls, in trenches and drains, and on equipment. Decontamination could be accomplished with the removal of approximately 1 m/sup 3/ of surface material, plus decontamination of drains, trenches, and equipment as appropriate.

Diurnal cortisol rhythms among Latino immigrants in Oregon, USA.  

PubMed

One of the most commonly used stress biomarkers is cortisol, a glucocorticoid hormone released by the adrenal glands that is central to the physiological stress response. Free cortisol can be measured in saliva and has been the biomarker of choice in stress studies measuring the function of the hypothalamic-pituitary-adrenal axis. Chronic psychosocial stress can lead to dysregulation of hypothalamic-pituitary-adrenal axis function and results in an abnormal diurnal cortisol profile. Little is known about objectively measured stress and health in Latino populations in the United States, yet this is likely an important factor in understanding health disparities that exist between Latinos and whites. The present study was designed to measure cortisol profiles among Latino immigrant farmworkers in Oregon (USA), and to compare quantitative and qualitative measures of stress in this population. Our results indicate that there were no sex differences in average cortisol AUCg (area under the curve with respect to the ground) over two days (AvgAUCg; males = 1.38, females = 1.60; P = 0.415). AUCg1 (Day 1 AUCg) and AvgAUCg were significantly negatively associated with age in men (P<0.05). AUCg1 was negatively associated with weight (P<0.05), waist circumference (P<0.01) and waist-to-stature ratio (P<0.05) in women, which is opposite of the expected relationship between cortisol and waist-to-stature ratio, possibly indicating hypothalamic-pituitary-adrenal axis dysregulation. Among men, more time in the United States and immigration to the United States at older ages predicted greater AvgAUCg. Among women, higher lifestyle incongruity was significantly related to greater AvgAUCg. Although preliminary, these results suggest that chronic psychosocial stress plays an important role in health risk in this population. PMID:22738123

Adverse experiences with implantable defibrillators in Oregon hospices  

PubMed Central

Background Implantable cardioverter-defibrillators (ICDs) improve survival in patients at risk for recurrent, sustained ventricular tachycardia or fibrillation. Unless deactivated, ICDs may deliver unwanted shocks to terminally ill patients near the time of death. This study sought to determine the frequency and nature of adverse experiences with ICDs events and what preventative measures the hospice programs had taken. Method A mailed survey to all 50 Oregon Hospice Programs in August 2008. Results 42/50 (84%) programs participated. 36/42 (86%) programs reported having taken care of a patient with an ICD in the preceding four years. The average number of patients with ICDs per program increased from 2.2 (SD 2.5) in 2005 & 2006 to 3.6 (SD 3.7) in 2007 & 2008. Of the 36 programs who had cared for a patient with an ICD, 31 (86%) reported having some kind of adverse experience. These ranged from unwanted shocks delivered (64%), patient/ family distress related to the decision to deactivate the ICD (47%), and time delay in ICD deactivation (42%). Only 16 (38%) programs had policies for managing ICDs and only 19 (43%) routinely screened new patients for ICDs. Discussion As patients near the end of their lives, receiving defibrillating shocks may no longer be consistent with their goals of care. Based on the high frequencies of potentially preventable adverse outcomes documented by this study, we propose that hospices routinely screen patients for ICDs and adopt policies to proactively manage them, rather than in response to an adverse event.

The Oregon Experiment -- Effects of Medicaid on Clinical Outcomes  

PubMed Central

BACKGROUND Despite the imminent expansion of Medicaid coverage for low-income adults, the effects of expanding coverage are unclear. The 2008 Medicaid expansion in Oregon based on lottery drawings from a waiting list provided an opportunity to evaluate these effects. METHODS Approximately 2 years after the lottery, we obtained data from 6387 adults who were randomly selected to be able to apply for Medicaid coverage and 5842 adults who were not selected. Measures included blood-pressure, cholesterol, and glycated hemoglobin levels; screening for depression; medication inventories; and self-reported diagnoses, health status, health care utilization, and out-of-pocket spending for such services. We used the random assignment in the lottery to calculate the effect of Medicaid coverage. RESULTS We found no significant effect of Medicaid coverage on the prevalence or diagnosis of hypertension or high cholesterol levels or on the use of medication for these conditions. Medicaid coverage significantly increased the probability of a diagnosis of diabetes and the use of diabetes medication, but we observed no significant effect on average glycated hemoglobin levels or on the percentage of participants with levels of 6.5% or higher. Medicaid coverage decreased the probability of a positive screening for depression (?9.15 percentage points; 95% confidence interval, ?16.70 to ?1.60; P = 0.02), increased the use of many preventive services, and nearly eliminated catastrophic out-of-pocket medical expenditures. CONCLUSIONS This randomized, controlled study showed that Medicaid coverage generated no significant improvements in measured physical health outcomes in the first 2 years, but it did increase use of health care services, raise rates of diabetes detection and management, lower rates of depression, and reduce financial strain.

Assessing automobile head restraint positioning in Portland, Oregon  

PubMed Central

Objective: Automobile head restraints, when used properly, have been shown to decrease the incidence and severity of whiplash injuries to the neck. Before the development of a public campaign on proper head restraint positioning, the authors assessed head restraint positioning and public understanding. Design: Over a one month period, the position of the vehicle head restraint of drivers was observed in moving cars in the city of Portland, Oregon (population 530 000). Optimal position was defined as having the head restraint above the ears with the back of the head touching the head restraint. A questionnaire on head restraint understanding was administered to people during jury service. Results: Of the 4287 drivers observed, 1% (n = 30) had no head restraint on their seat, 4% (n = 158) had a fixed head restraint, and 95% (n = 4099) had an adjustable head restraint. Among the fixed head restraints, 21% (33/158) were positioned optimally with no horizontal gap. Among the adjustable head restraints, only 7% (280/4099) had optimal head restraint positioning. Overall, 93% (3974/4287) of all head restraints observed were suboptimally positioned. Seventy five percent (38/51) of polled Portland residents identified safety as the primary head restraint function. Conclusion: Ninety three percent of all head restraints observed were suboptimally positioned. Fixed head restraints were three times more likely to be in optimal position than adjustable head restraints (21% v 7%). Most polled Portland residents understood the proper function and positioning of head restraints. This discrepancy between actual practice and understanding should be addressed with public education and manufacturer design changes.

Diurnal cortisol rhythms among Latino immigrants in Oregon, USA  

PubMed Central

One of the most commonly used stress biomarkers is cortisol, a glucocorticoid hormone released by the adrenal glands that is central to the physiological stress response. Free cortisol can be measured in saliva and has been the biomarker of choice in stress studies measuring the function of the hypothalamic-pituitary-adrenal axis. Chronic psychosocial stress can lead to dysregulation of hypothalamic-pituitary-adrenal axis function and results in an abnormal diurnal cortisol profile. Little is known about objectively measured stress and health in Latino populations in the United States, yet this is likely an important factor in understanding health disparities that exist between Latinos and whites. The present study was designed to measure cortisol profiles among Latino immigrant farmworkers in Oregon (USA), and to compare quantitative and qualitative measures of stress in this population. Our results indicate that there were no sex differences in average cortisol AUCg (area under the curve with respect to the ground) over two days (AvgAUCg; males?=?1.38, females?=?1.60; P?=?0.415). AUCg1 (Day 1 AUCg) and AvgAUCg were significantly negatively associated with age in men (P<0.05). AUCg1 was negatively associated with weight (P<0.05), waist circumference (P<0.01) and waist-to-stature ratio (P<0.05) in women, which is opposite of the expected relationship between cortisol and waist-to-stature ratio, possibly indicating hypothalamic-pituitary-adrenal axis dysregulation. Among men, more time in the United States and immigration to the United States at older ages predicted greater AvgAUCg. Among women, higher lifestyle incongruity was significantly related to greater AvgAUCg. Although preliminary, these results suggest that chronic psychosocial stress plays an important role in health risk in this population.

Diatom data from Bradley Lake, Oregon: downcore analyses  

USGS Publications Warehouse

Displaced marine diatoms provide biostratigraphic evidence for tsunami inundation at Bradley Lake, a small freshwater lake on the south-central Oregon coast. During the past 7,200 years, fine-grained lacustrine deposits in the deep axis of the lake were disturbed 17 times by the erosion and emplacement of coarse-grained gyttja and, in some cases, sand. By identifying diatoms in closely spaced core samples, we determined that 13 of the 17 events (termed idisturbance eventsi) record prehistoric tsunamis in Bradley Lake. We consider the evidence strong for 11 events, based on numbers and diversity of marine taxa: De1, De2, De4, De5, De6, De7, De8, De11, De12, De13, and De17. The evidence is less compelling for an additional 2 events (De9 and De10), although tsunami inundation is likely. Finally, we identified 4 events (De3, De14, De15 and De16) in which there were no marine diatoms to support tsunami inundation, although stratigraphic data shows that the lake bottom was disturbed. Freshwater diatoms dominate throughout the Bradley Lake record, showing that the lake has remained a freshwater habitat throughout its existence. However, anomalous occurrences of three species of brackish diatoms (Thalassiosira bramaputrae, Cyclotella meneghiniana, and Mastogloia smithii) may be evidence for short-lived periods of slightly elevated salinities in the lake following De16, De13, De12, De11, De9, De8, and De5. With the exception of De12, increased abundances of one or more of the brackish species is coincident with decreased numbers of freshwater diatoms. A temporary rise in salinity, as evidenced by short-lived increases in abundances of brackish species and decreases in abundances of freshwater species, is consistent with tsunami inundation into the lake.

Prioritising health services in an era of limits: the Oregon experience.  

PubMed Central

How do we decide who should receive the benefits that medical science has to offer? One approach to this decision process, that used by the state of Oregon, is described: who and what are covered, and how health care is financed and delivered, are considered. Oregon's priorities were set on the basis of broad consensus. The objective of health care reform, it was agreed, is to improve, maintain, or restore health--not universal coverage, access to health care, or cost containment. A Health Services Commission was created to consider clinical effectiveness and, through public involvement, to attempt to integrate social values into the priority list. Oregon's legislature can use the list to develop an overall health policy which recognises that health can be maintained only if investments in several related areas are balanced. Images p374-a

Lead poisoning associated with intravenous-methamphetamine use--Oregon, 1988  

SciTech Connect

Between August 1 and September 6, 1988, 14 cases of non-A, non-B (NANB) hepatitis were reported in Marion County, Oregon, to the Oregon Health Division (OHD) by the county health department and private physicians. Previously, an average of less than one case per month was reported in the county. During the same period, OHD learned that eight intravenous-methamphetamine users (IVMUs) in Oregon thought to have NANB hepatitis had also been recently diagnosed with lead poisoning. A statewide media campaign describing the lead poisoning outbreak was conducted to alert IVMUs, physicians, and county health departments. In addition, OHD implemented a reporting system for suspected and confirmed lead poisoning cases. Analysis of an illicit methamphetamine sample provided by one of the patients with confirmed lead poisoning detected 60% lead by weight.

What The Oregon Health Study Can Tell Us About Expanding Medicaid  

PubMed Central

The recently enacted Patient Protection and Affordable Care Act includes a major expansion of Medicaid to low-income adults in 2014. This paper describes the Oregon Health Study, a randomized controlled trial that will be able to shed some light on the likely effects of such expansions. In 2008, Oregon randomly drew names from a waiting list for its previously closed public insurance program. Our analysis of enrollment into this program found that people who signed up for the waiting list and enrolled in the Oregon Medicaid program were likely to have worse health than those who did not. However, actual enrollment was fairly low, partly because many applicants did not meet eligibility standards.

Rural Oregon community perspectives: introducing community-based participatory research into a community health coalition.  

PubMed

The Community Health Improvement Partnership (CHIP) model has supported community health development in more than 100 communities nationally. In 2011, four rural Oregon CHIPs collaborated with investigators from the Oregon Rural Practice-based Research Network (ORPRN), a component of the Oregon Clinical and Translational Research Institute (OCTRI), to obtain training on research methods, develop and implement pilot research studies on childhood obesity, and explore matches with academic partners. This article summarizes the experiences of the Lincoln County CHIP, established in 2003, as it transitioned from CHIP to Community Health Improvement and Research Partnership (CHIRP). Our story and lessons learned may inform rural community-based health coalitions and academicians who are engaged in or considering Community-based participatory research (CBPR) partnerships. Utilizing existing infrastructure and relationships in community and academic settings provides an ideal starting point for rural, bidirectional research partnerships. PMID:24056513

Geothermal greenhouse heating facilities for the Klamath County Nursing Home, Klamath Falls, Oregon  

NASA Astrophysics Data System (ADS)

The Klamath County Nursing Home, located in Klamath Falls, Oregon, was constructed in 1976. The building of 55,654 square feet currently houses care facilities for approximately 120 persons. During the initial planning for the nursing home, the present site was selected primarily on the basis of its geothermal resource. This resource currently provides space and domestic hot water heating for the nursing home, Merle West Medical Center and the Oregon Institute of Technology. The feasibility of installing a geothermal heating system in a planned greenhouse for the nursing home is explored. The greenhouse system would be tied directly to the existing hot water heating system for the nursing home.

Paleomagnetism of Basalt Flows near McKenzie Bridge, Oregon  

NASA Astrophysics Data System (ADS)

A section of twelve Quaternary basalt flows near McKenzie Bridge, Oregon was sampled in July 2004 for paleomagnetic analysis. The thick sequence was chosen for study because field surveys suggest it is the proper age to potentially record the Matuyama-Brunhes transition, and field measurements with a fluxgate magnetometer indicated the presence of both normal and reversely magnetized units (Conrey, pers. comm.). At each site, six to ten oriented cores were collected and analyzed to determine the mean magnetic direction and Virtual Geomagnetic Pole (VGP) position. Standard alternating field demagnetization to 999 oe and thermal demagnetization to 680° C were performed to remove secondary magnetization and get clues to magnetic mineralogy. Eleven of the twelve sites yielded VGPs that cluster in Eastern Siberia. The mean inclination and declination of these 11 sites are 59.5° and 328.3° with a95 = 2.95° . The remaining flow yielded radically different directions from the other sites (D = 278.8°, I = 8.7° ) and a VGP just north of Australia (lat. = 9.4° S long. = 145.0° ). Further investigation of this site needs to be done in order to ensure that the outcrop is in place and yielding a reliable magnetic direction. Changes in intensity during thermal demagnetizations suggest titano-magnetite as the main carrier of magnetic signal. SEM and optical examination will be used to confirm magnetic mineralogy. Assuming a Geocentric Axial Dipole (GAD) field, the expected mean direction for the McKenzie Bridge area is D = 0°, I = 63.4° . The difference in the expected and mean directions for the 11 sites can be explained in several ways. The area may have undergone counterclockwise rotation since these lavas were erupted, or the units sampled may not represent a long enough time period to adequately average paleosecular variatio
