Louisiana, Texas fabrication yards on busy upswing  

SciTech Connect

Responding to the continued push to produce natural gas reserves, Texas and Louisiana fabrication yards anticipate a busy 1994 season. Sixty-five oil and gas production platforms are under construction for major companies and independents; total platforms built in 1994 could approach 100. While oil prices are still volatile, most projects are focusing on shallow-water fields. Advanced technology has helped fabricators improve designs by making structures lighter and more cost-effective. PC-Based software helps yards perform more thorough analyses of a structure, which means towers and fixed platforms can be more economically built. Software also enables yards to design cost-effective structures to develop fields with a marginal level of reserves. Several projects currently under development or recently completed are described.

National Uranium Resource Evaluation: Palestine Quadrangle, Texas and Louisiana  

SciTech Connect

The uranium resource potential of the Palestine Quadrangle, Texas and Louisiana, was evaluated to a depth of 1500 m (5000 ft) using criteria established for the National Uranium Resource Evaluation program. Data derived from geochemical analyses of surface samples (substrate, soil, and stream sediment) in conjunction with hydrochemical data from water wells were used to evaluate geologic environments as being favorable or unfavorable for the occurrence of uranium deposits. Two favorable environments have been identified in the Palestine Quadrangle: potential deposits of modified Texas roll-type in fluvial channels and associated facies within the Yegua Formation, and potential occurrences along mineralization fronts associated with the Elkhart Graben and Mount Enterprise fault system. Unfavorable environments include: Cretaceous shales and limestones, Tertiary fine-grained marine sequences, Tertiary sandstone units that exhibit favorable host-rock characteristics but fail to show significant syngenetic or epigenetic mineralization, and Quaternary sands and gravels. Unevaluated units include the Woodbine Group (Upper Cretaceous), Jackson Group (Tertiary), and Catahoula Formation (Tertiary). The subsurface interval of the Jackson Group and Catahoula Formation contains depositional facies that may represent favorable environments; however, the evaluation of these units is inconclusive because of the general lack of shallow subsurface control and core material. The Woodbine Group, restricted to the subsurface except for a small exposure over Palestine Dome, occurs above 1500 m (5000 ft) in the northwest quarter of the quadrangle. The unit exhibits favorable host-rock characteristics, but the paucity of gamma logs and cores, as well as the lack of hydrogeochemical and stream-sediment reconnaissance data, makes evaluation of the unit difficult.

Environmental contaminants in redheads wintering in coastal Louisiana and Texas

Whole body and liver analyses indicated that wintering redheads (Aythya americana; n=70) in coastal Louisiana (one site) and Texas (two sites) were relatively free of contamination with common trace elements, organochlorines, and hydrocarbons. Most trace elements, including As, Cr, Hg, Mg, Mn, Ni, Pb, Se, Sr, and Zn, were within background concentrations in livers; levels of B, Cd, Cu, and Fe were elevated in some specimens. Only one organochlorine, DDE, was detected in redhead carcasses, but its concentration was below reported toxic levels in waterfowl. Body burdens of aliphatic and aromatic hydrocarbons were generally low, but levels of pristane, total hydrocarbons, and the ratios of phytane:n-octadecane and pristane:n-heptadecane were indicative of possible chronic exposure to petroleum. Based on brain cholinesterase assays, redheads were not recently exposed to organophosphorous or carbamate pesticides. Of 30 elements or compounds tested for seasonal differences, only Se increased from early to late winter at one of the three sites. Eight of 57 contaminants differed among the three sites; no sex or age differences were found.

Recoverable Resource Estimate of Identified Onshore Geopressured Geothermal Energy in Texas and Louisiana (Presentation)  

SciTech Connect

Geopressured geothermal reservoirs are characterized by high temperatures and high pressures with correspondingly large quantities of dissolved methane. Due to these characteristics, the reservoirs provide two sources of energy: chemical energy from the recovered methane, and thermal energy from the recovered fluid at temperatures high enough to operate a binary power plant for electricity production. Formations with the greatest potential for recoverable energy are located in the gulf coastal region of Texas and Louisiana where significantly overpressured and hot formations are abundant. This study estimates the total recoverable onshore geopressured geothermal resource for identified sites in Texas and Louisiana. In this study a geopressured geothermal resource is defined as a brine reservoir with fluid temperature greater than 212 degrees F and a pressure gradient greater than 0.7 psi/ft.

Origin of the Tertiary reservoired hydrocarbons along the central Texas and Louisiana Gulf Coast rim  

SciTech Connect

Tertiary reservoired hydrocarbons along the central Texas and Louisiana Gulf Coast rim were most likely derived from Paleocene/Eocene Wilcox Group and Sparta Formation marine shales. Sixteen total soluble extracts and >200 oil samples were analyzed using carbon isotopic techniques ({delta}{sup 13}C) and gas chromatography-mass spectometry (GC-MS). Results demonstrated that interpretations must use all types of data because Cretaceous derived and Tertiary derived oils overlap in southern Louisiana. When isotopic, sterane, hopane, and light hydrocarbon data are combined separation of classes become possible. Cretaceous oils and extracts have a full range of extended hopanes, a characteristic peak eluting immediately after C{sub 30} hopane and no oleanane. Paleogene oils and extracts have oleanane and a restricted range of extended hopanes. Regional trends indicate that eastern Louisiana oils were derived from the Sparta or a Sparta/Wilcox mix, the Mississippi delta oils from a Cretaceous clastic source, and western Louisiana and Texas oils from the Wilcox source. Regional variations in GOR/CGR are a function of timing and mechanism of migration.

Hazardous substances releases associated with Hurricanes Katrina and Rita in industrial settings, Louisiana and Texas.  

PubMed

The scientific literature concerning the public health response to the unprecedented hurricanes striking the Gulf Coast in August and September 2005 has focused mainly on assessing health-related needs and surveillance of injuries, infectious diseases, and other illnesses. However, the hurricanes also resulted in unintended hazardous substances releases in the affected states. Data from two states (Louisiana and Texas) participating in the Hazardous Substances Emergency Events Surveillance (HSEES) system were analyzed to describe the characteristics of hazardous substances releases in industrial settings associated with Hurricanes Katrina and Rita. HSEES is an active multi-state Web-based surveillance system maintained by the Agency for Toxic Substances and Disease Registry (ATSDR). In 2005, 166 hurricane-related hazardous substances events in industrial settings in Louisiana and Texas were reported. Most (72.3%) releases were due to emergency shut downs in preparation for the hurricanes and start-ups after the hurricanes. Emphasis is given to the contributing causal factors, hazardous substances released, and event scenarios. Recommendations are made to prevent or minimize acute releases of hazardous substances during future hurricanes, including installing backup power generation, securing equipment and piping to withstand high winds, establishing procedures to shutdown process operations safely, following established and up-to-date start-up procedures and checklists, and carefully performing pre-start-up safety reviews.

Differences in the stratigraphic framework of the Frio and Anahuac Formations in the Louisiana and Texas Gulf Coast Basin  

SciTech Connect

The hydrocarbon endowment of the Frio and Anahuac formations of Louisiana and Texas has made them the most thoroughly studied geologic strata in the Gulf Coast Basin. A review of previous studies of the stratigraphic framework of the Frio and Anahuac formations in the Louisiana and Texas Gulf Coast Basin reveals that researchers have placed the boundary between the Frio and Anahuac in this basin at different biostratigraphic and lithostratigraphic levels. This review also reveals that in some previous studies the subdivision of the Frio in Texas into lower, middle, and upper zones does not conform with the traditional biostratigraphic zonation scheme. Biostratigraphically, the index fossils used to mark the boundary between the Frio and Anahuac differ in the Texas Gulf Coast from those employed in the Louisiana Gulf Coast. In the subsurface Frio of Louisiana, the paleontologic top of the Frio is historically placed at the highest occurrence of Camerina sp. A. In the subsurface Frio of Texas, the paleontologic top of the Frio is historically marked by the highest occurrence of Cibicides hazzardi. Although microfossils; characteristic of the Camerina A zone are reported from wells penetrating the subsurface Anahuac and Frio, their occurrence has proven too erratic to be employed in a regionally correlatable biostratigraphic framework. This review also shows that some workers place the lithostratigraphic top of the Frio in the Texas Gulf Coast Basin just above the first sands lying below the Anahuac shale wedge. These sands are actually lower Anahuac Marginulina sands in the lower and middle Texas Gulf Coast and upper Frio Cibicides hazzardi sands in the upper Texas Gulf Coast, depending on the dip position of the particular well.

Coastal sea level response to frontal passages on the Louisiana-Texas shelf  

NASA Astrophysics Data System (ADS)

Sea level variations resulting from wind forcing along the Louisiana-Texas shelf are examined on 5-month winter records. Local weather patterns during the winter are dominated by cold-front passages. The associated surface wind field is well organized, predominantly in the cross-shelf direction. Regional sea level response, however, shows considerable variability; it is mainly a response to alongshore wind at Galveston, but cross-shelf wind at Eugene Island. This spatially nonuniform response appears to be due to the different water depth over the inner shelf, which is shallower off Eugene Island and favors direct cross-shelf wind setup. A friction model is applied to each region, and the results compare well with observations.

Estimating shorebird populations during spring stopover in rice fields of the Louisiana and Texas Gulf Coastal Plain  

USGS Publications Warehouse

Migrating shorebird populations using approximately 2% of Louisiana and Texas Gulf Coastal rice fields were surveyed during spring migration (March–May of 1997 and 1998) using biweekly stratified random surveys conducted at 50 roadside survey points and approximately 30,000 shorebirds were observed. Shorebird counts were extrapolated and almost 1.4 million birds in 1997 and over 1.6 million birds of 31 species in 1998 were estimated to use rice field habitat for stopover sites in Louisiana and Texas. Greater than 50% of the estimated North American populations were estimated to use rice field habitats for five species, including a species of concern, Buff-breasted Sandpiper (Tryngites subruficollis) at 187%. Because of predictability of suitable rice field habitat acreage, timing of field preparation and water availability, coastal rice prairies are identified as critical spring migration stopover sites.

Hurricane Rita surge data, southwestern Louisiana and southeastern Texas, September to November 2005  

USGS Publications Warehouse

Pressure transducers and high-water marks were used to document the inland water levels related to storm surge generated by Hurricane Rita in southwestern Louisiana and southeastern Texas. On September 22-23, 2005, an experimental monitoring network consisting of 47 pressure transducers (sensors) was deployed at 33 sites over an area of about 4,000 square miles to record the timing, extent, and magnitude of inland hurricane storm surge and coastal flooding. Sensors were programmed to record date and time, temperature, and barometric or water pressure. Water pressure was corrected for changes in barometric pressure and salinity. Elevation surveys using global-positioning systems and differential levels were used to relate all storm-surge water-level data, reference marks, benchmarks, sensor measuring points, and high-water marks to the North American Vertical Datum of 1988 (NAVD 88). The resulting data indicated that storm-surge water levels over 14 feet above NAVD 88 occurred at three locations and rates of water-level rise greater than 5 feet per hour occurred at three locations near the Louisiana coast. Quality-assurance measures were used to assess the variability and accuracy of the water-level data recorded by the sensors. Water-level data from sensors were similar to data from co-located sensors, permanent U.S. Geological Survey streamgages, and water-surface elevations performed by field staff. Water-level data from sensors at selected locations were compared to corresponding high-water mark elevations. In general, the water-level data from sensors were similar to elevations of high quality high-water marks, while reporting consistently higher than elevations of lesser quality high-water marks.

Morbidity surveillance after Hurricane Katrina--Arkansas, Louisiana, Mississippi, and Texas, September 2005.  

PubMed

Hurricane Katrina made landfall on the U.S. Gulf Coast on August 29, 2005. Thousands of Gulf Coast residents evacuated and dispersed across the country, moving into hotels, private homes, and evacuation centers (ECs) in 30 states and the District of Columbia (DC). One goal of public health responders was to identify and prevent hurricane-related morbidity and mortality among affected populations, especially among those with limited access to health care and those who were living in crowded conditions. This report summarizes the challenges of conducting national surveillance after Hurricane Katrina, focusing on the role of CDC in coordinating surveillance and consolidating and interpreting morbidity data from jurisdictions that used diverse surveillance approaches. Aggregate morbidity data that were reported through Arkansas, Louisiana, Mississippi, and Texas to CDC during September 1-22, 2005 (before the Gulf Coast landfall of Hurricane Rita on September 24) are presented from ECs and health-care facilities (HCFs) that served affected populations in these states. Chronic diseases and injuries were the most common conditions reported by ECs and HCFs, respectively. To better prepare for future large-scale disasters with widespread impact, public health agencies and other partners are actively working to establish standardized guidelines and tools for morbidity surveillance. These guidelines will facilitate the interpretation and exchange of health information among multiple jurisdictions and public and private agencies during a disaster response to identify outbreaks and monitor health concerns.

Virulence and biotype analyses of Hessian fly (Diptera: Cecidomyiidae) populations from Texas, Louisiana, and Oklahoma.  

PubMed

Hessian fly, Mayetiola destructor (Say, 1817), is a major pest of wheat, and is controlled mainly through deploying fly-resistant wheat cultivars. The challenge for the plant resistance approach is that virulence of Hessian fly populations in the field is dynamic, and wheat cultivars may lose resistance within 6-8 yr. To ensure continuous success of host plant resistance, Hessian fly populations in the field need to be constantly monitored to determine which resistance genes remain effective in different geographic regions. This study investigated five Hessian fly populations collected from Texas, Louisiana, and Oklahoma, where infestation by Hessian fly has been high in recent years. Eight resistance genes, H12, H13, H17, H18, H22, H25, H26, and Hdic, were found to be highly effective against all tested Hessian fly populations in this region, conferring resistance to > or = 80% of plants containing one of these resistance genes. The frequencies ofbiotypes virulent to resistance genes H13 (biotype vH13), H18 (vH18), H21 (vH21), H25 (vH25), H26 (vH26), and Hdic (vHdic) were determined, and were found to vary from population to population, ranging from 0 to 45%. A logistic regression model was established to predict biotype frequencies based on the correlation between the percentages of susceptible plants obtained in a virulence test and the log-odds of virulent biotype frequencies determined by a traditional approach.

This report presents the preliminary environmental findings from the first phase of the Environmental Survey of the United States Department of Energy (DOE) Strategic Petroleum Reserve (SPR), located in Louisiana and Texas, and conducted in two segments from November 30 through December 11, 1987, and February 1 through 10, 1988. The Survey is being conducted by a multidisciplinary team of environmental specialists led and managed by the Office of Environment, Safety and Health's Office of Environmental Audit. Individual team specialists are outside experts being supplied by a private contractor. The objective of the Survey is to identify environmental problems and areas of environmental risk associated with SPR. The Survey covers all environmental media and all areas of environmental regulation. It is being performed in accordance with the DOE Environmental Survey Manual. This phase of the Survey involved the review of existing site environmental data, observations of the operations carried on at SPR, and interviews with site personnel. The Survey team has developed a Sampling and Analysis Plan to assist in further assessing specific environmental problems identified during its on-site activities. The Sampling and Analysis Plan will be executed by Idaho National Engineering Laboratory. When completed, the results will be incorporated into the SPR Survey findings for inclusion into the Environmental Survey Summary Report. The Summary Report will reflect the final determinations of the SPR Survey and the other DOE site-specific Surveys. 200 refs., 50 figs., 30 tabs.

Subsurface Glen Rose reef trend in east Texas and west-central Louisiana  

SciTech Connect

The subsurface Glen Rose reef trend in east Texas and west-central Louisiana (Lower Cretaceous Comanchean) is a regressive carbonate complex deposited on a broad shallow water shelf. The Glen Rose reef trend can be differentiated into two separate reef tracts that prograded seaward over a slowly subsiding shelf. It remains to be seen whether the Glen Rose reefs are actual framework reefs or mounds of transported material. Reef facies include poorly sorted caprinidcoral grainstones, moderately sorted peloid and oncolite packstones and grainstones, and well-sorted, very fine grained skeletal grainstones. Coated grains, abraded skeletal fragments, scoured bedding surfaces, and minor cross-beds are evidence for deposition of the reef facies in a high-energy shoal setting. The reefal buildups grade laterally into low-energy shallow water wackestones and mudstones containing toucasids, orbitolinids, and serpulid burrows. Porosities associated with the reefal buildups appear facies controlled. Caprinid-coral packstones and grainstones exhibit intraparticle, moldic, and vuggy porosities of 10 to 15%. Pinpoint microporosity of 5 to 10% are found within the finegrained skeletal grainstones. Fracture porosity enhances permeability in several facies. Moldic and vuggy porosity types are generally secondary whereas intraparticle porosity may be preserved primary. Coarse equant calcite commonly occludes intraparticle, moldic, vuggy, and fracture porosities. Dolomitization within the reef limestones may have acted to create or preserve porosities. Poor production from the Glen Rose reef trend has been attributed to the lack of structural closure.

Evaluation of Primary Safety Belt Laws in California, Louisiana, and Georgia  

PubMed Central

This study evaluated three states that changed to primary enforcement of safety belt laws, collecting statewide seat belt observation data for several years and conducting monthly seat belt observations for 6 months after passage of the primary law in 6 California cities, 5 Louisiana cities, and 5 Georgia cities (average 1,000–6,000 vehicles a month); monthly motorist surveys at DMVs for 6 months in these sites (n=7,061); focus groups with law enforcement officers and supervisors in each site; and citations issued locally and statewide for several years. Observed belt use increased substantially in California (+18 percentage points) and in Louisiana (+16 percentage points). Smaller increases were seen in Georgia initially, but grew the following year. In each state, most motorists understood that they could be stopped by a police officer for a belt use violation alone. In Louisiana and Georgia, there was no evidence that one racial group was targeted for enforcement as compared to any other racial group.

Geologic and hydrologic summary of salt domes in Gulf Coast region of Texas, Louisiana, Mississippi, and Alabama  

USGS Publications Warehouse

There are 263 known or suspected onshore salt domes in the Texas-Louisiana-Mississippi-Alabama portion of the Gulf Coast geosyncline. The top of the salt in 148 of them is probably deeper than desirable for a waste repository site, and 79 of those that are shallow enough are probably unavailable for a site because of present use by industry for gas storage or production of oil, salt, or sulfur. In this report we have compiled the available geologic and hydrologic background data pertinent to the evaluation of the remaining 36 known or suspected salt domes as potential sites for waste storage. There are three parts to this compilations: 1) summaries of the geology and hydrology of the salt-dome province as a whole; 2) summaries of the physiography, climate, geology, and hydrology of each of the five salt-dome basins that occur within the province; and 3) an appendix of background data for each of the 36 potentially acceptable domes. The distribution of salt domes in the province is genetically related to areas of relative subsidence that formed basins or depocenters within the Gulf Coast geosyncline. In some cases, as in northeast Texas and south Louisiana, the locations of individual domes or groups of domes are related to deep movement of salt along axial trends. The salt domes in the interior salt-dome subprovince are probably more structurally stable than those of the coastal subprovince because salt diapirism is inferred to have ceased around Miocene time in the interior but may still be active in parts of the coastal subprovince. Although the size and shape of many domes is unknown or can only be roughly approximated, each of the five basins in the province appears to contain potentially acceptable domes of adequate size for a repository. We recognize no pattern to the distribution of salt-dome size. Caprock thicknesses vary greatly within each salt-dome basin,and we recognize no pattern to the variations. Among the potentially acceptable domes, the depths to the top of the salt are generally greatest in the Mississippi salt-dome basin, where all tops are more than 1,500 feet deep. Intermediate depths of about 1,000 feet are common in the east Texas-south Louisiana salt-dome basin. Depths to salt tops in the north Louisiana and northeast Texas basins are variable but most are less than 1,000 feet. Available drilling records are generally adequate to determine the number of wells drilled on or in the vicinity of individual domes and also the well locations. The numbers of wells vary widely within each salt-dome basin. More salt domes are currently available for use as repository sites in the interior subprovince than in the coastal subprovince, where the pressure for industrial use of domes is high. In the interior subprovince many of the potentially acceptable domes are located beneath hilly well-drained terrain that is not subject to flooding or other surface-water problems. Although topographic depressions occupied by shallow lakes, swamps, or 'salines' occur over several of the domes, they are generally flanked by topographically high ground where surface facilities could be sited without complications.A few of the potentially acceptable domes are located beneath floodplains where surface facilities might face hazards from flooding. In the coastal subprovince several of the potentially acceptable domes are located in relatively flat poorly drained terrain where surface flooding might constitute a potential hazard. The availability of fresh to slightly saline ground water varies considerably within each salt-dome basin. We have outlined some of the factors that are responsible for the variations and have provided or referred to maps and geohydrologic cross sections that illustrate the general distribution of fresh to slightly saline water. The top of the salt in about half of the known potentially acceptable domes is below the regional base of the fresh to slightly saline ground-water system, but in a few of

Impact of improved technology on potential reserves of tight gas in East Texas and Northwestern Louisiana. Final topical report, October 1, 1989-September 30, 1990  

SciTech Connect

The East Texas/Northwestern Louisiana area has been one of the most active tight gas plays over the past decade. Advances in formation evaluation and stimulation technologies offer the prospect of increased reserves at reduced costs from remaining tight gas resource. The purpose of the study was to estimate the remaining potential production from the low permeability portions of the Cotton Valley and Travis Peak Formations, the largest tight gas formations in the area. For a 14,000 square mile study area that straddles the Texas/Louisiana border and the Sabine Uplift, a remaining estimated 2.8 Tcf is technically recoverable from the Cotton Valley Sand and 1.2 Tcf from the Upper Travis Peak. These estimates were based on a regional geologic appraisal of currently producing reservoirs. Typical wells were analyzed and used as the basis to extrapolate expected future production from the remaining undeveloped areas of these reservoirs. The analysis incorporated potential improvements in formation evaluation and stimulation technologies and current costing and industry financial parameters to estimate potential reserves at alternative wellhead prices. Reservoir data and analysis results can be used to identify which geological and technical parameters are most important to efficient recovery of East Texas tight sands. Three case studies are also presented of improved technologies in the study area over the past decade. The studies indicate that technology improvements have been made in the design and implementation of new stimulation technologies, as well as in formation evaluation and reservoir management.

Global Positioning System Surveys of Storm-Surge Sensors Deployed During Hurricane Ike, Seadrift, Texas, to Lake Charles, Louisiana, 2008  

USGS Publications Warehouse

The U.S. Geological Survey installed a network of pressure sensors at 65 sites along the Gulf Coast from Seadrift, Texas, northeast to Lake Charles, Louisiana, to record the timing, areal extent, and magnitude of inland storm surge and coastal flooding caused by Hurricane Ike in September 2008. A Global Positioning System was used to obtain elevations of reference marks near each sensor. A combination of real-time kinematic (RTK) and static Global Positioning System surveys were done to obtain elevations of reference marks. Leveling relative to reference marks was done to obtain elevations of sensor orifices above the reference marks. This report summarizes the Global Positioning System data collected and processed to obtain reference mark and storm-sensor-orifice elevations for 59 storm-surge sensors recovered from the original 65 installed as a necessary prelude to computation of storm-surge elevations. National Geodetic Survey benchmarks were used for RTK surveying. Where National Geodetic Survey benchmarks were not within 12 kilometers of a sensor site, static surveying was done. Additional control points for static surveying were in the form of newly established benchmarks or reestablished existing benchmarks. RTK surveying was used to obtain positions and elevations of reference marks for 29 sensor sites. Static surveying was used to obtain positions and elevations of reference marks for 34 sensor sites; four sites were surveyed using both methods. Multiple quality checks on the RTK-survey and static-survey data were applied. The results of all quality checks indicate that the desired elevation accuracy for the surveys of this report, less than 0.1-meter error, was achieved.

Sea surface temperature and the brown shrimp ( Farfantepenaeus aztecus) population on the Alabama, Mississippi, Louisiana and Texas continental shelves  

NASA Astrophysics Data System (ADS)

Analysis of the Southeast Area Monitoring and Assessment Program - Gulf of Mexico (SEAMAP-GM) summer and fall trawl survey data covering the Alabama, Mississippi, Louisiana and Texas continental shelves for the period 1987-2000 shows that the annual number n and weight w of the brown shrimp per trawl is positively correlated with annual sea surface temperature (SST) averaged over the continental shelves. Correlations of the monthly anomalous SST by calendar month with the annual shrimp data are highest in April and May. Past work has suggested a possible reason for this: juvenile brown shrimp, which mainly develop from postlarvae in coastal estuaries in April and May, grow faster in warmer water and are therefore more likely to escape predators. Since the juvenile shrimp population is a good predictor of the adult shelf shrimp population, and since the estuarine and shelf SST are closely linked, it is reasonable that April and May shelf SST should be positively correlated with the number and weight of brown shrimp per trawl. Shrimp are more numerous in the summer and the correlation of April and May SST anomaly is much higher for the number and weight per trawl in the summer than in the fall. Hindcasts are made using the simple linear statistical prediction model n=?+?·SSTA, where SSTA is the anomalous April-May departure of SST from the annual cycle. The cross-verified correlation between model and observed n is r = 0.77. A similar model for w gave r = 0.79. A prediction model for summer shrimp alone had cross-verified correlations r = 0.79 for n and 0.86 for w. Based on the 2004 April-May SST anomaly, annual and summer models predict that n and w should be close to average in 2004.

The cross-verified correlation between model and observed n is r=0.77 . A similar model for w gave r=0.79 . In 2004, the model predicts that the number and weight of the brown shrimp should be less than those in 1999 and 2000, but still larger than the average values from 1987 to 2000 (5.92% above normal for the number and 5.64% above for the weight).

Strategic Petroleum Reserve Texoma Complex distribution enhancements: Orange and Jefferson Counties, Texas; Calcasieu and Cameron Parishes, Louisiana: Environmental assessment  

SciTech Connect

The Department of Energy is proposing to construct and operate two buried crude oil pipelines to provide for unconstrained drawdown of three Strategic Petroleum Reserve (SPR) crude oil storage facilities of the Texoma Complex located in portions of Louisiana and Texas. The project is required to provide a crude oil distribution system capable of meeting a planned increase in the Texoma Complex drawdown rate to 2,340,000 barrels-per-day (bpd). The EA addresses a no-action alternative and alternative pipeline routes. Potential impacts from pipeline construction concern disturbances to prime farmlands, floodplains and wetlands. A very small acreage of prime farmlands is involved; the total is not considered significant. The Floodplain/Wetlands Assessment states that the effects of pipeline construction and operation on floodplains and associated wetlands will be temporary and localized. DOE determined in a Floodplain Statement of Findings that for the project as a whole there is no practicable alternative to locating in a floodplain, and that the proposal conforms to appropriate state and local floodplain protection standards. Potential impacts from pipeline operation are primarily concerned with accidental releases of crude oil to the environment. Because the pipelines will be buried, the probability of a major pipeline break releasing large quantities of crude oil is small and pipeline testing and the development of an oil spill contingency plan will reduce the seriousness of any oil spill. The proposed pipelines are expected to involve no other environmental concerns. It is the determination of DOE that the proposed Texoma Complex Distribution Enhancements do not constitute a major federal action significantly affecting the quality of the human environment; therefore an environmental impact statement will not be prepared. 27 refs., 3 tabs.

Mercury speciation and biomagnification in the food web of Caddo Lake, Texas and Louisiana, USA, a subtropical freshwater ecosystem.  

PubMed

We studied the biomagnification of total mercury and methylmercury in a subtropical freshwater lake, Caddo Lake, Texas and Louisiana, USA. The present study is unique in that it not only included invertebrates (seven species) and fish (six species) but also an amphibian (one species), reptiles (three species), and mammals (three species). Nonfish vertebrates such as those included in the present study are often not included in assessments of trophic transfer of Hg. Mean trophic position (determined using stable isotopes of nitrogen) ranged from 2.0 (indicative of a primary consumer) to 3.8 (indicative of a tertiary consumer). Mean total Hg concentrations ranged from 36 to 3,292 ng/g dry weight in muscle and whole body and from 150 to 30,171 ng/g dry weight in liver. Most of the Hg in muscle and whole-body tissue was found as methylmercury, and at least 50% of the Hg found in liver was in the inorganic form (with the exception of largemouth bass, Micropterus salmoides). Mercury concentrations were positively correlated with trophic position, indicating that biomagnification occurs in the food web of Caddo Lake. The food web magnification factors (FWMFs; slope of the relationship between mean Hg concentration and trophic position) for both total Hg and methylmercury were similar to those observed in other studies. Because most of the total Hg in consumers was methylmercury, the FWMF for methylmercury was not significantly different from the FWMF for total Hg. Some vertebrates examined in the present study had low Hg concentrations in their tissues similar to those observed in invertebrates, whereas others had concentrations of Hg in their tissues that in previous studies have been associated with negative health consequences in fish.

Temporal variation of summertime denitrification rates in the Texas-Louisiana inner shelf region in the Gulf of Mexico: A modeling approach using the extended OMP analysis  

NASA Astrophysics Data System (ADS)

The northern Gulf of Mexico (GOM) is well known for hypoxic water conditions (O2?2 mg L-1), and is often referred to as the "Dead Zone". The area of the Dead Zone has increased remarkably during the recent decades due to the increased coastal eutrophication. Under such conditions, denitrification process that removes "available nitrogen" from the system would likely become more active, and it needs to be better quantified to understand the nature of biogeochemical nitrogen cycles in the northern GOM. Despite its significance, few denitrification studies have been conducted for this area. We estimate the temporal variation of denitrification rates of the bottom waters at the northern Gulf of Mexico encompassing the "Dead Zone" during July of the 1985-2007 period (except for 1988-1990). We use historic hydrographic data and the extended Optimum Multi-Parameter analysis. Denitrification rates of the bottom waters in the region have gradually decreased from 1985 to 1997, and then increased to 2007. The water mass mixing composition of bottom waters on the Texas-Louisiana inner shelf has changed since ˜1997. The Texas-Louisiana Coastal Water part has increased and that of the Subtropical Underwater has decreased. This change appears to have influenced the denitrification rates in the study area. We suggest that denitrification rates of bottom waters in the northern Gulf of Mexico are controlled not only by biogeochemical factors (i.e. organic matter supply and remineralization), but also by physical factor (i.e. stratification and relative contributions from different water masses).

Elevations and discharges produced by a simulated flood wave on the lower Sabine River, Louisiana and Texas, caused by a theoretical dam failure  

USGS Publications Warehouse

The Toledo Bend Reservoir is located on the lower Sabine River between Louisiana and Texas. Two mathematical models were coupled to calculate the flood wave that would result from the theoretical failure of 25 percent of Toledo Bend Dam and route the wave downstream to Orange, Tex. Computations assumed failure (1) at the peak of the 100-year flood when discharge of the Sabine River is 102,000 cubic feet per second and (2) when the average discharge is 10,000 cubic feet per second. Two techniques were used in the dam-break model. The method of characteristics was used to propagate the shock wave following dam failure. The linear implicit finite-difference solution was used to route the flood wave following shock wave dissipation. The magnitude of the flow was determined for Burkeville, Bon Wier, Ruliff, and Orange, Tex., along the lower Sabine River. For these sites, respectively, the following peak elevations were calculated: 119, 82, 31, and 13 feet for the 100-year flood and 110, 75, 27, and 9 feet for the average discharge. (Woodard-USGS)

Man-made marine debris and sea turtle strandings on beaches of the upper Texas and southwestern Louisiana coasts, June 1987 through September 1989. Technical memo  

SciTech Connect

The upper Texas and southwestern Louisiana coastlines were divided into six sampling zones to survey the amounts, types and rates of accumulation of man-made marine debris, the number of sea turtle strandings, the incidence of sea turtle entanglements in marine debris and the incidence of ingestion of such debris by sea turtles. From June 1987 through September 1989, 473 sample plots were examined for marine debris. Significant differences were detected in mean number of debris items per 100 sq m of beach sampled by year, zone and month. Significant differences in mean weight of debris items per 100 sq m of beach sampled were detected by month and zone. Both number and weights (per 100 sq m) of debris were lowest in the winter months. Number per 100 sq m was greatest in August while weight per 100 sq m peaked in May. Tar balls and plastic items were the most frequently encountered marine debris items. Wooden items had the highest average weights while tar balls and polystyrene foam were the lightest items collected. A total of 171 sea turtles stranded on the surveyed beaches during the study. Of 26 gastrointestinal tracts examined, 16 had ingested some form of man-made debris. Six turtles were entangled in man-made debris and 9 were live stranded.

SciTech Connect

The Department of Energy (DOE) has initiated a program to evaluate the feasibility of developing the geothermal-geopressured energy resources of the Louisiana-Texas Gulf Coast. As part of this effort, DOE is contracting for the drilling of design wells to define the nature and extent of the geopressure resource. At each of several sites, one deep well (4000-6400 m) will be drilled and flow tested. One or more shallow wells will also be drilled to dispose of geopressured brines. Each site will require about 2 ha (5 acres) of land. Construction and initial flow testing will take approximately one year. If initial flow testing is successful, a continuous one-year duration flow test will take place at a rate of up to 6400 m{sup 3} (40,000 bbl) per day. Extensive tests will be conducted on the physical and chemical composition of the fluids, on their temperature and flow rate, on fluid disposal techniques, and on the reliability and performance of equipment. Each project will require a maximum of three years to complete drilling, testing, and site restoration.

Trends in selected streamflow statistics at 19 long-term streamflow-gaging stations indicative of outflows from Texas to Arkansas, Louisiana, Galveston Bay, and the Gulf of Mexico, 1922-2009  

USGS Publications Warehouse

Trends in selected streamflow statistics during 1922-2009 were evaluated at 19 long-term streamflow-gaging stations considered indicative of outflows from Texas to Arkansas, Louisiana, Galveston Bay, and the Gulf of Mexico. The U.S. Geological Survey, in cooperation with the Texas Water Development Board, evaluated streamflow data from streamflow-gaging stations with more than 50 years of record that were active as of 2009. The outflows into Arkansas and Louisiana were represented by 3 streamflow-gaging stations, and outflows into the Gulf of Mexico, including Galveston Bay, were represented by 16 streamflow-gaging stations. Monotonic trend analyses were done using the following three streamflow statistics generated from daily mean values of streamflow: (1) annual mean daily discharge, (2) annual maximum daily discharge, and (3) annual minimum daily discharge. The trend analyses were based on the nonparametric Kendall's Tau test, which is useful for the detection of monotonic upward or downward trends with time. A total of 69 trend analyses by Kendall's Tau were computed - 19 periods of streamflow multiplied by the 3 streamflow statistics plus 12 additional trend analyses because the periods of record for 2 streamflow-gaging stations were divided into periods representing pre- and post-reservoir impoundment. Unless otherwise described, each trend analysis used the entire period of record for each streamflow-gaging station. The monotonic trend analysis detected 11 statistically significant downward trends, 37 instances of no trend, and 21 statistically significant upward trends. One general region studied, which seemingly has relatively more upward trends for many of the streamflow statistics analyzed, includes the rivers and associated creeks and bayous to Galveston Bay in the Houston metropolitan area. Lastly, the most western river basins considered (the Nueces and Rio Grande) had statistically significant downward trends for many of the streamflow statistics analyzed.

Molecular distinction between populations of Gonatocerus morrilli, egg parasitoids of the glassy-winged sharpshooter from Texas and California: Do cryptic species exist?  

PubMed Central

Two molecular methods were utilized to distinguish geographic populations of Gonatocerus morrilli (Howard) from Texas and California and to test the possibility that this species could exist as a species-complex. Inter-Simple Sequence Repeat–Polymerase Chain Reactions (ISSR–PCR) were performed with a 5?-anchored ISSR primer. Twenty-five markers were generated with four populations (40 individuals) of G. morrilli. Twenty-three were polymorphic and the percentage of polymorphic loci was 92%. Most markers could be considered diagnostic since there was no band sharing between the Texas and California populations. Such differences typically are not found unless the populations are reproductively isolated. Exact tests for population differentiation indicated significant differences in marker frequencies among the populations. Comparison of other genetic differentiation estimates, which evaluate the degree of genetic subdivision, demonstrated excellent agreement between GST and ? values, 0.92 and 0.94, respectively, indicating that about 92 to 94% of the variance was distributed among populations. The average genetic divergence (D), as measured by genetic distance, was extremely high (Nei = 0.82 and Reynolds = 2.79). A dendrogram based on Nei's genetic distance separated the Texas and California populations into two clusters, respectively. Amplification of the Internal Transcribed Spacer-1 (ITS-1) region showed no size differences, whereas the ITS-2 DNA fragment varied in size between the two geographic populations. The ITS-2 fragment sizes were about 865 and 1099 base pairs for the California and Texas populations, respectively. The present study using the two molecular methods provides novel data critical to the glassy-winged sharpshooter/Pierce's disease biological control program in California.

The data from bird eggs were too few for conclusions, but to detect peak residue loads, future dicofol studies should concentrate on predaceous bird species likely to feed within the treated agricultural habitats, and collecting of eggs for analysis should begin within days after spray application.

Petroleum systems and geologic assessment of undiscovered oil and gas, Cotton Valley group and Travis Peak-Hosston formations, East Texas basin and Louisiana-Mississippi salt basins provinces of the northern Gulf Coast region. Chapters 1-7.  

USGS Publications Warehouse

The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The USGS recently completed an assessment of undiscovered oil and gas potential of the Cotton Valley Group and Travis Peak and Hosston Formations in the East Texas Basin and Louisiana-Mississippi Salt Basins Provinces in the Gulf Coast Region (USGS Provinces 5048 and 5049). The Cotton Valley Group and Travis Peak and Hosston Formations are important because of their potential for natural gas resources. This assessment is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). The USGS used this geologic framework to define one total petroleum system and eight assessment units. Seven assessment units were quantitatively assessed for undiscovered oil and gas resources.

An Overview of Historical Channel Adjustment and Selected Hydraulic Values in the Lower Sabine and Lower Brazos River Basins, Texas and Louisiana  

USGS Publications Warehouse

The Sabine and Brazos are alluvial rivers; alluvial rivers are dynamic systems that adjust their geometry in response to changes in streamflow (discharge) and sediment load. In fluvial geomorphology, the term 'channel adjustment' refers to river channel changes in three geometric dimensions: (1) channel slope (profile); (2) the outline or shape, such as meandering or braided, projected on a horizontal plane (planform); and (3) cross-sectional form (shape). The primary objective of the study was to investigate how the channel morphology of these rivers has changed in response to reservoirs and other anthropogenic disturbances that have altered streamflow and sediment load. The results of this study are expected to aid ecological assessments in the lower Sabine River and lower Brazos River Basins for the Texas Instream Flow Program. Starting in the 1920s, several dams have been constructed on the Sabine and Brazos Rivers and their tributaries, and numerous bridges have been built and sometimes replaced multiple times, which have changed the natural flow regime and reduced or altered sediment loads downstream. Changes in channel geometry over time can reduce channel conveyance and thus streamflow, which can have adverse ecological effects. Channel attributes including cross-section form, channel slope, and planform change were evaluated to learn how each river's morphology changed over many years in response to natural and anthropogenic disturbances. Climate has large influence on the hydrologic regimes of the lower Sabine and lower Brazos River Basins. Equally important as climate in controlling the hydrologic regime of the two river systems are numerous reservoirs that regulate downstream flow releases. The hydrologic regimes of the two rivers and their tributaries reflect the combined influences of climate, flow regulation, and drainage area. Historical and contemporary cross-sectional channel geometries at 15 streamflow-gaging stations in the lower Sabine and lower Brazos River Basins were evaluated. An in-depth discussion of results from streamflow-gaging station 08028500 Sabine River near Bon Weir, Tex., is featured here as an example of the analyses that were done at each station.

Status of the peregrine falcon in the Rocky Mountains and the southwestern United States, Baja California, and Mexico (south of Texas)  

USGS Publications Warehouse

About 31 pairs of peregrines still nest north of Mexico, from Idaho and Montana south through West Texas, New Mexico and Arizona. At least thirty-six additional pairs nest in Mexico. Although the nesting sites are occupied, the tissues of the peregrine?s prey species still contain high concentrations of pesticides. The eggs in some Rocky Mountain eyries have shells which are precariously thin and have high residue levels of DDE in their contents. Increasing economic development is encroaching on the peregrine habitat throughout its range in western North America. In Baja California. and Mexico south of Texas this involves increased agricultural activity including use of organochlorine pesticides, increased tourism and increased use of the Gulf of California both for commercial and sport fishing, with their potential disturbance of eyrie sites and reduction of the peregrine?s aquatic feeding prey base. As the fish in the Gulf decrease in number, some of the avian species on which peregrines prey will likewise decrease. This ultimately may effect the peregrine. These factors may have been involved in the demise of the peregrine on Baja California?s Pacific coast. Furthermore, throughout its range, residential, industrial, mining, geothermal, recreational and other types of development and land use practices sometimes destroy habitat essential to the survival of the peregrine. A recent request for the protection of an historical site in California as Critical Habitat under Section 7 of the Endangered Species Act was rejected because peregrines, although observed there, were not known to have produced eggs or young at the site for several decades. With inadequate protection of abandoned, but still suitable, historical eyrie sites, the peregrine may have an insufficient number of eyries to reoccupy in recovery attempts. The lack of present occupancy of a site, without biological evidence that the site is no longer suitable for reoccupancy, is insufficient cause to give up the site to the pressures of development. Since destruction of habitat is forever, preservation of this essential habitat is of utmost importance to the survival of the species. On the other hand, we must not allow the peregrine, or other of the endangered species, to be used as levers for the sole purpose of restricting economic development. When an impasse between the two does occur, our defense of the endangered species must be justified on sound biological evidence if the Endangered Species Act of 1973 is to survive. The formation of the recovery teams, the development of recovery plans, and the success of captive breeding and reintroduction projects are all on the plus side of the ledger for the peregrine. They suggest optimism for the future of the peregrine, providing use of DDT is restricted both north and south of our southern border, and a sufficient number of the still suitable inactive eyrie sites are preserved to effect recovery. We need to categorize all active and inactive sites on the basis of quality and/or suitability for reoccupancy and preserve those required for the recovery of the species. Categorizing inactive eyries as to suitability for reoccupancy will provide land management agencies information badly needed for critical value judgements affecting the future of the peregrine falcon in the West.

Louisiana: European Explorations and the Louisiana Purchase  

NSDL National Science Digital Library

When a young United States finalized the Louisiana Purchase in 1803, they in some ways literally didn't know what they were getting. Certainly a number of surveyors, explorers, and Native Americans had traversed different segments of this vast territory, but it had by no means been completely explored and documented. Recently, the American Memory Project at the Library of Congress created this rather delightful online collection that tells the historical and cultural story of the European explorations of these lands. The collection contains 119 items such as a Native American map of the Upper Missouri from 1801 and the "Accurate Map of North America" by Emmanuel Bowen from 1767. First-time visitors should make a point of reading the 118-page explanatory essay offered here. It covers such topics as the cartographic setting of the Purchase and Louisiana's tenure as a Spanish colony.

Afro-Louisiana History and Genealogy  

NSDL National Science Digital Library

In 1984, Dr. Gwendolyn Hall, a professor emerita of history at Rutgers University, stumbled upon a treasure of historical data in a courthouse in Pointe Coupee Parish, Louisiana. For the next 15 years, Dr. Hall rummaged through documents from all over Louisiana (as well as archives in France, Spain and Texas) and uncovered the background of approximately 100,000 slaves who were brought to Louisiana in the 18th and 19th centuries. Armed with this information, Dr. Hall designed and created a database into which she recorded and calculated the information she obtained from these documents regarding African slave names, genders, ages, occupations, illnesses, family relationships, ethnicity, places of origin, prices paid by slave owners, and slave testimonials and emancipations. Together, Dr. Hall, the Center for the Public Domain, and ibiblio.org presents this online collection of significant historical data. The user-friendly database is searchable by name, gender, racial designation, and plantation or origin. From historians, genealogists, anthropologists, geneticists, and linguists, to Americans seeking keys to their past, there are many who can benefit from this freely accessible information.

Vegetation Types in Coastal Louisiana in 2007  

USGS Publications Warehouse

During the summer and fall of 2007, the U.S. Geological Survey, the Louisiana State University Agricultural Center, and the Louisiana Department of Wildlife and Fisheries Fur and Refuge Division jointly completed an aerial survey to collect data on 2007 vegetation types in coastal Louisiana. The current map presents the data collected in this effort. The 2007 aerial survey was conducted by using techniques developed over the last thirty years while conducting similar vegetation surveys. Transects flown were oriented in a north-south direction and spaced 1.87 mi (3 km) apart and covered coastal marshes from the Texas State line to the Mississippi State line and from the northern extent of fresh marshes to the southern end of saline (saltwater) marshes on the beaches of the Gulf of Mexico or of coastal bays. Navigation along these transects and to each sampling site was accomplished by using Global Positioning System (GPS) technology and geographic information system (GIS) software. As the surveyors reached each sampling station, observed areas of marsh were assigned as fresh, intermediate, brackish, or saline (saltwater) types, and dominant plant species were listed and ranked according to abundance. Delineations of marsh boundaries usually followed natural levees, bayous, or other features that impede or restrict water flow.

Louisiana Coastal Ecosystem  

USGS Publications Warehouse

Louisiana's coast and its degradation and restoration are major environmental issues being studied at the National Wetlands Research Center. Coastal ecosystems are vulnerable because of the tremendous amount of human activity that takes place along the coast. Information on ecological processes is essential to guide the development along the coast as well as to protect and restore wildlife habitat. Louisiana has about 40% of coastal wetlands in the lower 48 states; they support fish, waterfowl, and fur-bearing animals as well as unique cultures like that of the Acadians. The fish and wildlife resources of Louisiana's coast produce over $1 billion each year in revenues. But Louisiana has the highest coastal loss rate because of natural and human causes. Over the past three decades, Louisiana has lost as much as 35-40 mi2 (90-104 km2) of coastal wetlands a year. The National Wetlands Research Center is qualified to assess and monitor this ecosystem because of its proximity to the study area, a staff chosen for their expertise in the system, and a number of established partnerships with others who study the areas. The Center is often the lead group in partnerships with universities, other federal agencies, and private entities who study this ecosystem. Most of the Center's research and technology development performed for coastal wetlands are done at the Lafayette headquarters; some work is performed at the National Wetlands Research Center's project office in Baton Rouge, LA.

Of this total, wildcat wells numbered 269, exploratory wells numbered 232, and development wells numbered 889. On a percentage basis, 7% of all wildcat wells, 39% of all exploratory wells, and 59% of all development wells were successful completions. Wildcat drilling activity resulted in 19 new field discoveries during 1980. Total onshore leasing activity increased for the first time since 1976. Leasing in the district during 1980 amounted to 1,491,621 ac. This was a 51% increase over the 989,630 ac leased during 1979. Avoyelles, Tangipahoa, St. Helena, Terrebonne, and St. Landry parishes recorded the highest levels of leasing activity during the year. Geophysical activity in the Louisiana Gulf Coast onshore district increased for the eighth consecutive year. During 1980, the total geophysical activity amounted to 1656 crew weeks, marking an increase of 331 crew weeks over the 1979 total of 1325 crew weeks. The highest levels of geophysical activity were recorded in Cameron, Vermilion, Terrebonne, Tangipahoa, and St. Tammany parishes. The current high level of exploration activity in south Louisiana is expected to continue for the next several years.

Sea level rise in Louisiana and Gulf of Mexico  

SciTech Connect

Data from two tide-gage networks in Louisiana and the northern Gulf of Mexico were analyzed to determine local and regional trends in relative sea level rise. The US Army Corps of Engineers (USACE) maintains a network of 83 tide-gage stations throughout coastal Louisiana. Of these, 20 have records for two lunar nodal cycles or more, and some date back to 1933. The authors used the USACE data set to determine the local and regional character of relative sea level rise in Louisiana. The National ocean Survey (NOS) maintains nine tide gage stations throughout the northern Gulf of Mexico in Texas, Louisiana, Mississippi, Alabama, and Florida. All of the records of these stations exceed two lunar nodal cycles, and some date back to 1908. The authors used the NOS data set to determine the character of relative sea level rise throughout the northern Gulf of Mexico. This investigation updates and extends the previous systematic regional tide gage analysis (which covered 1908-1983) to 1988.

KISATCHIE HILLS WILDERNESS, LOUISIANA.  

USGS Publications Warehouse

A mineral-resource survey of the Kisatchie Hills Wilderness, Louisiana indicated little promise for the occurrence of mineral resources. There is insufficient data on oil and gas producing formations that underlie the area to evaluate the oil and gas resource potential. All the oil fields of Wilcox age are less than 40 acres in extent; therefore, closer spaced deeper wells might find additional fields in sediments of Wilcox age. Oil and natural gas have been produced from older reservoirs (Cretaceous age) to the northwest of the wilderness, and deeper wells might find oil and natural gas in sediments of Cretaceous and older age in the vicinity of the wilderness.

Survival of female northern pintails wintering in southwestern Louisiana  

USGS Publications Warehouse

The North American breeding population of northern pintails (Anas acuta) has reached previously unprecedented low numbers 4 times since 1983. Because pintails show high fidelity to wintering areas, regional survival estimates and identification of factors influencing survival are needed to guide management of wintering pintails. We used raidiotelemetry to estimate survival rates of female pintails wintering in southwestern Lousiaina. We tested for variation in survival and hunting mortality rates in realtiaon to age (immature or adult), winter (1990-91, 1991-92, 1992-93), time period (prehunting season, first hunting season, time between split hunting seasons, second hunting season, posthunting season), body condition (body mass when released, adjusted for body size), and region (southwestern Louisiana or elsewhere on the Texas-Louisiana Gulf Coast or Mississippi Alluvial Valley).

Winter status of White-eyed Vireos in northeastern Louisiana

In December 2004, February 2005, and June 2005, we recaptured a White-eyed Vireo (Vireo griseus) that was banded on 19 May 2004 at the same location on the Tensas River National Wildlife Refuge, Madison Parish, LA. This is the first documented permanent resident White-eyed Vireo outside of resident populations known from Florida and southern Texas. This individual appears to be resident near the northern limit of the winter range for the species. Although White-eyed Vireos are uncommon in northeastern Louisiana during winter, we detected other White-eyed Vireos during line transect surveys and banding during winters 2003-2004 and 2004-2005. The lack of research and observation of winter birds in northern Louisiana and the secretive and inconspicuous behavior of White-eyed Vireos in winter may have led to an underestimation of abundance at the northern limits of their winter range.

Tropospheric Ozone in Louisiana and Synoptic Circulation.  

NASA Astrophysics Data System (ADS)

Tropospheric ozone (O3) is a pollutant of increasing concern in many urban areas in the United States. There is an increasing need to understand the geographical and meteorological properties associated with O3, particularly because of the changing criteria that are being implemented by the U.S. Environmental Protection Agency to monitor O3. This research examines the relationship between O3 mixing ratios in Louisiana and surface and low-tropospheric synoptic circulation patterns. Results suggest that local conditions and synoptic influences are both important in determining the behavior of observed O3 in Louisiana during this period in which “exceedance” frequencies decreased until 2000 01, at which time they increased again. Furthermore, the expected pattern of surface anticyclonic activity, low-tropospheric ridging, weak pressure gradients, and subsidence from the lower troposphere is found to be associated with anomalously high O3, both at most local sites in the state and on days with anomalously high O3 statewide. More surprising, however, is the tendency for high O3 to be associated with low surface pressure in the Great Plains, perhaps in advance of a midlatitude wave cyclone to the north. This and other surface patterns may be linked to advection from the southeastern Texas urban industrial corridor. A temporally increasing tendency for surface and lower-tropospheric ridging over the 1994 2001 study period provides at least a partial explanation for the absence of a frequency decline in statewide anomalously high ozone days during a time of increasing public awareness and concern for meeting the O3 standard.

Azodrin® poisoning of waterfowl in rice fields in Louisiana  

USGS Publications Warehouse

During the period 2-4 April 1981 about 100 birds, mostly ducks and geese, were found dead and dying in a rice field near Sweet Lake, Calcasieu Parish, Louisiana. Fresh specimens were collected to determine the cause of mortality. Birds were placed individually in polyethylene freezer bags, tagged, and frozen soon after collection. Four snow geese (Chen caerulescens), two blue-winged teal (Anas discors), one green-winged teal (Anas crecca), and one mottled duck (Anas fulvigula) were shipped to the National Wildlife Health Laboratory (NWHL), Madison, Wisconsin, for necropsy and pathological examination. Ten snow geese, 10 blue-winged teal, three green-winged teal, three great-tailed grackles (Quiscalus mexicanus), and eight red-winged blackbirds (Agelaius phoeniceus) were transported to the Gulf Coast Field Station, Victoria, Texas, for brain acetylcholinesterase (AChE) activity determinations and preparation for chemical residue analysis. Additionally, apparently healthy specimens of the affected species were collected near Lake Charles, Louisiana, and Victoria, Texas, to serve as controls in the analyses.

Pancreatic cancer mortality in Louisiana.  

PubMed Central

As a preliminary step in the investigation of high pancreas-cancer mortality among White males in a cluster of Louisiana parishes, we examined 876 pairs of certificates of death which occurred in this area during 1960--75. The pancreas-cancer death records were matched to controls by age, race, sex, year of death, and parish of residence. The odds ratios were increased about two-fold for workers in the oil refining and paper manufacturing industries, and slight elevations were seen among residents near refineries and food processing plants. Despite the limited residential and occupational information available on death certificates, this study suggests leads to environmental factors that can be further investigated by a case-control interview study in Louisiana.

Technical support for geopressured-geothermal well activities in Louisiana  

SciTech Connect

Continuous recording microearthquake monitoring networks have been established around US Department of Energy (DOE) geopressured-geothermal design wells in southwestern Louisiana and southeastern Texas since summer 1980 to assess the effects well development may have had on subsidence and growth-fault activation. This monitoring has shown several unusual characteristics of Gulf Coast seismic activity. The observed activity is classified into two dominant types, one with identifiable body phases (type 1) and the other with only surface-wave signatures (type 2). During this reporting period no type 1 or body-wave events were reported. A total of 230 type 2 or surface-wave events were recorded. Origins of the type 2 events are still not positively understood; however, little or no evidence is available to connect them with geopressured-geothermal well activity. We continue to suspect sonic booms from military aircraft or some other human-induced source. 37 refs., 16 figs., 6 tabs.

GAO specifically urged maintaining the collaborative process that is used by Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) program agencies, with scientists, engineers, and others working together to plan and design restoration projects. The report also noted the need to address such other issues as having an integrated monitoring system to determine whether goals and objectives are met as well as to understand that projects can encounter significant setbacks due to storms and hurricanes, landscape and structural causes, and spiraling project costs. Louisiana state officials anticipate the state could receive about $8.5 billion over the next 10 years for coastal restoration and protection. Nearly 40% of all coastal wetlands in the lower 48 U.S. states are located in Louisiana. For more information, visit the Web site: http://www.gao.gov/new.items/d08130.pdf.

The Louisiana ACES Student-built BalloonSat Program  

NASA Astrophysics Data System (ADS)

The Aerospace Catalyst Experiences for Students (ACES) pilot project was funded at Louisiana State University by NASA's National Space Grant College and Fellowship program during the 2002-2003 academic year with the primary goal of giving students a true hands-on experience with project management, life-cycle, experiment construction, data collection, analysis and interpretation. In this project students design, build, fly and analyze the data returned from small payloads (typical dimensions 10 cm x 10 cm x 10 cm, typical weight ˜ 500 grams) carried up to ˜ 100,000 feet by a helium-filled latex sounding balloon. During the pilot project the 13 students that participated in the program, grouped in 4 teams, built payloads that included studies in atmospheric science, cosmic rays and remote sensing. These payloads were then launched from the NASA National Scientific Balloon Facility in Palestine, Texas on May 21, 2003. Most recently, the LaACES (Louisiana ACES) program has been selected for funding by NASA. During LaACES we will expand the pilot program to institutions across the state including developing student training materials, holding a workshop for institution representatives, awarding payload development grants to student teams, monitoring the progress of these teams and supporting the balloon flight of the completed payloads. Here we describe the ACES pilot, the outcomes, and plans for La ACES.

Denitrification in cypress swamp within the Atchafalaya River Basin, Louisiana.  

PubMed

Nitrogen has been implicated as a major cause of hypoxia in shallow water along the Louisiana/Texas, USA coasts. Excess nitrogen (mainly nitrate) from Mississippi and Atchafalaya River drainage basins may drive the onset and duration of hypoxia in the northern Gulf of Mexico. Restoring and enhancing denitrification have been proposed to reduce and control coastal hypoxia and improve water quality in the Mississippi River Basin. Sediments were collected from six baldcypress restoration sites within the Atchafalaya River Basin, Louisiana, USA. The acetylene blockage technique was used to measure background and potential sediment denitrification rates. Denitrification fluxes were measured before nitrate addition (background rates) and after nitrate addition of 100mgNl(-1) (potential denitrification) at three seasonal temperatures. Background denitrification was low across all cypress swamp sites ranging from 0.9 to 8.8, 0.6 to 28.5 and 8.8 to 47.5g N evolved ha(-1)d(-1) at water/sediment column temperatures of 8, 22 and 30 degrees C, respectively. After nitrate addition, temperature had a significant effect on sediment denitrification potential. Maximum rates measured at 8, 22 and 30 degrees C were approximately 250-260, 550 and 970gNha(-1)d(-1), respectively. Most of the added nitrate in water columns, incubated at 8 degrees C, was removed after 65d compared to 32d and 17d at 22 and 30 degrees C, respectively. These results indicate cypress swamps have the potential to assimilate and process elevated levels of floodwater nitrate with denitrification being a major removal mechanism. PMID:17707455

Mortality experience for Louisiana chemical workers.  

PubMed

A previous mortality study for Louisiana workers of The Dow Chemical Company identified greater than expected deaths due to leukemia and aleukemia and cancer of the brain and central nervous system. The current study updated the mortality experience through 1992. No new deaths due to leukemia and aleukemia and only one new death due to cancer of the brain and central nervous system were observed. No causes of death were statistically significantly elevated. The number of observed deaths was statistically significantly less than expected for a number of disease categories. Mortality rates were not shown to be higher among Louisiana chemical employees when compared to the United States, state, and regional populations. PMID:11280814

Prevalence of trichinosis in southern Louisiana swine  

SciTech Connect

After an outbreak of human trichinosis in Louisiana involving 45 cases and 1 death in 1979 and 1980, a survey of pigs killed in 21 selected small slaughterhouses in southwestern Louisiana was conducted from November 1980 to September 1981. The sera from 1,225 pigs were examined for trichinella antibodies using an enzyme-linked immunosorbent assay (ELISA); 1,223 diaphragms were subjected to peptic digestion and examined for the presence of Trichinella spiralis larvae. One diaphragm (0.08%) was found to contain T spiralis (26 larvae/g of muscle) and 4 of the slaughterhouse sera were positive (0.33% seroprevalence). Pigs in 52 herds throughout the state were also tested for ELISA antibodies. The ELISA-positive pigs were not found among the 267 pigs tested from the 52 herds.

Louisiana NASA EPSCoR Preparation Grant  

NASA Technical Reports Server (NTRS)

In August, 1999, the National Aeronautics and Space Administration issued a Cooperative Agreement (CA) to the State of Louisiana, through the Louisiana Board of Regents (BOB), for the performance of scientific research and graduate fellowships under the NASA Experimental Program to Stimulate Competitive Research (EPSCoR) -- Preparation Grant. Originally constructed as a one year program, with an optional one year continuation, this federal-state partnership culminated on 14 August 2002, including a successful continuation proposal and a no cost extension. The total value of the project reached $450K in NASA funding, matched by state funds and institutional contributions. The purpose of the Preparation Grant program was to develop and nurture strong research ties between the state and NASA field centers and Enterprises, in order to prepare for the upcoming full competition for NASA EPSCoR.

Epidemiological factors of cancer in Louisiana.  

PubMed

Certain Louisiana cancer rates are higher than the national averages. This review evaluates the existing epidemiologic literature pertaining to risk factors for cancer in Louisiana. Population-based case-control studies have identified smoking as the most important contributor to lung cancer in Louisiana. Nutritional factors have been found to impart a modest increase in lung, pancreas, and stomach cancer risk. Occupational epidemiologic studies have revealed exposure to asbestos in the cement, shipbuilding, and related industries as a significant risk factor for mesothelioma and lung cancer. Sugarcane farming has been found to increase the risk of lung cancer among sugarcane farmers who smoke, and the risk of mesothelioma among sugarcane farmers in general. Occupations with exposure to microwave and radio frequency electromagnetic radiation have been associated with an increased risk of brain cancer. An increased risk of laryngeal cancer has been observed among workers exposed to sulfuric acid at a Baton Rouge isopropyl alcohol plant. Except for the laryngeal cancer finding, data from occupational cohort studies of refinery/chemical workers revealed no significant excess in cancer of all sites, cancer of the lung, or any other cancer. Relevant epidemiologic data also revealed no increased cancer risk associated with potential exposures to industrial emissions among residents in communities adjacent to petrochemical facilities.

The Texas Twin Project  

PubMed Central

Socioeconomic position, racial/ethnic minority status, and other characteristics of the macro-environment may be important moderators of genetic influence on a wide array of psychosocial outcomes. Designed to maximize representation of low socioeconomic status families and racial/ethnic minorities, the Texas Twin Project is an on-going study of school-age twins (preschool through 12th grade) enrolled in public schools in the Austin, Texas and Houston, Texas metropolitan areas. School rosters are used to identify twin families from a target population with sizable populations of African-American (18%), Hispanic / Latino (48%), and non-Hispanic White (27%) children and adolescents, over half of whom meet U.S. guidelines for classification as economically disadvantaged. Initial efforts have focused on a large-scale, family-based survey study involving both parent and child reports of personality, psychopathology, physical health, academic interests, parent-child relationships, and aspects of the home environment. In addition, the Texas Twin Project is the basis for an in-laboratory study of adolescent decision-making, delinquency, and substance use. Future directions include geographic expansion of the sample to the entire state of Texas (with a population of over 25 million people) and genotyping of participating twins.

Smoke from widespread fires in tropical Mexico and Central America appears to be drifting over the U.S. Gulf States. In 1998 similar circumstances resulted in air-quality warnings being issued in several U.S. states, including Texas and Louisiana. The top image shows smoke and fires (red pixels) observed by the Moderate-Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra satellite. Possibly hundreds of small fires are scattered across Guatemala, Belize, Honduras, and Mexico's Yucatan Peninsula. The lower image, acquired by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), shows smoke from these fires carried by the prevailing winds across the Gulf of Mexico and over the United States.

Seismicity of west Texas  

SciTech Connect

A four year seismic study has found the Basin and Range province of west Texas and the adjacent area of Mexico to be more seismically active then than heretofore known. A University of Texas five station seismic array around the Marfa Basin has located or detected approximately 800 local and regional earthquakes with S-P times of less than 30 sec. A crustal model for the Basin and Range is derived from natural and artificial sources and contains four layers having velocities of 3.60, 4.93, 6.11, and 6.60 km/sec, respectively, overlying a mantle of 8.37 km/sec. A moderate level of seismic activity has been detected near Van Horn, in the Marfa Basin, and along the Texas-Mexico border between latitudes 30 and 31/sup 0/N. Five earthquake sequences were recorded, two near the Texas-Mexico border and three in the Marfa Basin. Four of these sequences showed quiescent periods in foreshock activity preceding the main shock. On the eastern side of the Marfa Basin a diffuse linear seismic zone may represent an unmapped fault, striking N 50/sup 0/W that coincides with Muehlberger's proposed eastern boundary of Basin and Range faulting. A new epicenter for the Valentine, Texas earthquake of August 16, 1931 has been relocated instrumentally at the northern end of this diffuse zone. Regional and local teleseismic P-wave arrival time anomalies observed for the nearby Gnome underground nuclear explosion of 1961 are used to determine station corrections and thus to locate the new 1931 epicenter at 3.69/sup 0/N, 104.57/sup 0/W. Several estimates of magnitude (m/sub b/) based on intensity data range from 5.6 to 6.4. Fault-plane and composite fault-plane solutions support Muehlberger's hypothesis that the Basin and Range is undergoing extension in a SW-NE direction.

Coastal Louisiana in Crisis: Subsidence or Sea Level Rise?  

NASA Astrophysics Data System (ADS)

The drowning of wetlands and barrier islands in coastal Louisiana has become a widely publicized environmental catastrophe in the wake of hurricanes Katrina and Rita in 2005. The devastation caused by these storms has reenergized the debate about restoring the natural coastal-defense system and building higher and sturdier levees, in anticipation of future storms. Understanding the contributions of land subsidence and eustatic (global) sea level rise to Louisiana's wetland loss is crucial to the success of any plan designed to protect coastal communities. It is argued here that accelerated sea level rise in the future may pose a larger threat than subsidence for considerable portions of coastal Louisiana.

In response to the Deepwater Horizon oil spill, sediment samples that were projected to have a high probability of being impacted by the oil were collected from shoreline zones of Texas, Louisiana, Mississippi, Alabama, and Florida. Sixty-one sites were sampled and analyzed for hydraulic conductivity, porosity, and grain-size distribution. The objective of this effort was to provide a set of baseline data on sediment characteristics known to directly influence (1) the penetration of oil into coastal sediments and (2) the efficacy of chemical and (or) bioremediation.

Louisiana hydrologic atlas map no. 1 : Mean annual runoff in Louisiana  

USGS Publications Warehouse

The map shows the mean annual runoff from drainage basins in Louisiana exclusive of those in the coastal zone and the alluvial valleys of the Mississippi, Ouachita, and Red Rivers. The mean annual runoff for the State of Louisiana varies from 0.7 (cu ft/s)/sq mi in the Sabine and Red River basins to >2.0 (cu ft/s)/sq mi in the upper reaches of the Mermentau River. Factors that account for the three-fold variation in runoff across Louisiana include regional differences in rainfall, varying physical characteristics of the land, and differing land use patterns. The mean annual runoff was determined on the basis of continuing measurements of stage and discharge of uncontrolled streams. The periods of record from the 88 stations shown on the map vary from 5 to 25 yr. The 88 stations were grouped into seven categories of runoff. The boundaries for each region generally correspond to drainage boundaries or physiographic boundaries. (Peters-PTT)

EPA Superfund Records of Decision (RODs) for Region 6: Arkansas, Louisiana, New Mexico, Oklahoma, and Texas  

SciTech Connect

The purpose of an EPA Record of Decision is to evaluate a Superfund Site with the goal of protecting human health and the environment while ensuring consistency of evaluations in contamination and clean-up of all Superfund sites. The ROD is a public document signed by the appropriate Regional Administrator which details cleanup, cost estimates, and EPA`s responsiveness to the public comment summary. The ROD may be litigated, thus it is important to have all current updates to the signed EPA decision. The ROD may be amended with an Amendment or supplemented by an Explanation of Significant Difference (ESD). A Superfund Site may have multiple RODs, as each Superfund Site may be further redefined as Operable Units and Events. This allows EPA`s decisions to evolve as new technology presents itself.

Flood monitoring network in southeastern Louisiana  

USGS Publications Warehouse

A flood monitoring network has been established to alert emergency operations personnel and the public about hydrologic conditions in the Amite River Basin. The U.S. Geological Survey (USGS), in cooperation with the Louisiana Office of Emergency Preparedness (LOEP), has installed a real-time data acquisition system to monitor rainfall and river stages in the basin. These data will be transmitted for use by emergency operations personnel to develop flood control and evacuation strategies. The current river stages at selected gaging stations in the basin also will be broadcast by local television and radio stations during a flood. Residents can record the changing river stages on a basin monitoring map, similar to a hurricane tracking map.

Achievement Gap in Texas  

NSDL National Science Digital Library

This 2010 PhysTEC Conference presentation discusses data, mainly from Texas, and mainly from high-stakes mathematics tests, that illustrate the very different educational outcomes for well-off and low-income students. A range of descriptive statistics that describe student performance within a single year is presented before longitudinal data is examined. Some of the questions addressed include: What are the grades at which low-income students fall behind the fastest? Do ethnic background and low income have independent effects on student outcomes? How do charter schools compare with ordinary public schools? Which students are disappearing from the school system, and when does it happen? Is the pressure of the accountability system having an effect on college readiness? Which are the high-performing schools and forward-looking educational policies that will increase, for example, the numbers of research physicists? Averages and results for schools throughout Texas are presented.

Abandoned Texas oil fields  

SciTech Connect

Data for Texas abandoned oil fields were primarily derived from two sources: (1) Texas Railroad Commission (TRRC), and (2) Dwight's ENERGYDATA. For purposes of this report, abandoned oil fields are defined as those fields that had no production during 1977. The TRRC OILMASTER computer tapes were used to identify these abandoned oil fields. The tapes also provided data on formation depth, gravity of oil production, location (both district and county), discovery date, and the cumulative production of the field since its discovery. In all, the computer tapes identified 9211 abandoned fields, most of which had less than 250,000 barrel cumulative production. This report focuses on the 676 abandoned onshore Texas oil fields that had cumulative production of over 250,000 barrels. The Dwight's ENERGYDATA computer tapes provided production histories for approximately two-thirds of the larger fields abandoned in 1966 and thereafter. Fields which ceased production prior to 1966 will show no production history nor abandonment date in this report. The Department of Energy hopes the general availability of these data will catalyze the private sector recovery of this unproduced resource.

Climate Variability and Sugarcane Yield in Louisiana.  

NASA Astrophysics Data System (ADS)

This paper seeks to understand the role that climate variability has on annual yield of sugarcane in Louisiana. Unique features of sugarcane growth in Louisiana and nonclimatic, yield-influencing factors make this goal an interesting and challenging one. Several methods of seeking and establishing the relations between yield and climate variables are employed. First, yield climate relations were investigated at a single research station where crop variety and growing conditions could be held constant and yield relations could be established between a predominant older crop variety and a newer one. Interviews with crop experts and a literature survey were used to identify potential climatic factors that control yield. A statistical analysis was performed using statewide yield data from the American Sugar Cane League from 1963 to 2002 and a climate database. Yield values for later years were adjusted downward to form an adjusted yield dataset. The climate database was principally constructed from daily and monthly values of maximum and minimum temperature and daily and monthly total precipitation for six cooperative weather-reporting stations representative of the area of sugarcane production. The influence of 74 different, though not independent, climate-related variables on sugarcane yield was investigated. The fact that a climate signal exists is demonstrated by comparing mean values of the climate variables corresponding to the upper and lower third of adjusted yield values. Most of these mean-value differences show an intuitively plausible difference between the high- and low-yield years. The difference between means of the climate variables for years corresponding to the upper and lower third of annual yield values for 13 of the variables is statistically significant at or above the 90% level. A correlation matrix was used to identify the variables that had the largest influence on annual yield. Four variables [called here critical climatic variables (CCV)], mean maximum August temperature, mean minimum February temperature, soil water surplus between April and September, and occurrence of autumn (fall) hurricanes, were built into a model to simulate adjusted yield values. The CCV model simulates the yield value with an rmse of 5.1 t ha-1. The mean of the adjusted yield data over the study period was 60.4 t ha-1, with values for the highest and lowest years being 73.1 and 50.6 t ha-1, respectively, and a standard deviation of 5.9 t ha-1. Presumably because of the almost constant high water table and soil water availability, higher precipitation totals, which are inversely related to radiation and temperature, tend to have a negative effect on the yields. Past trends in the values of critical climatic variables and general projections of future climate suggest that, with respect to the climatic environment and as long as land drainage is continued and maintained, future levels of sugarcane yield will rise in Louisiana.

Water resources of Natchitoches Parish, Louisiana  

USGS Publications Warehouse

In 2005, about 33.8 million gallons per day (Mgal/d) was withdrawn from water sources in Natchitoches Parish, Louisiana. Surface water sources accounted for about 86 percent (29.2 Mgal/d) of all withdrawals whereas groundwater sources accounted for about 14 percent (4.62 Mgal/d). Withdrawals for industrial use accounted for about 42 percent (14.1 Mgal/d) of the total water withdrawn (table 2). Other categories of use included public supply, rural domestic, livestock, rice irrigation, general irrigation, and aquaculture. The city of Natchitoches used almost 5.6 Mgal/d (about 5.2 Mgal/d of surface water and 0.4 Mgal/d of ground water) for public supply. Water-use data collected at 5-year intervals from 1960 to 2005 indicated that total water withdrawals increased from about 3.5 Mgal/d in 1960 to a peak of almost 35 Mgal/d in 2000. This fact sheet summarizes basic information on the water resources of Natchitoches Parish. Information on groundwater and surface-water availability, quality, development, use, and trends is based on previously published reports listed in the Selected References section.

Towards sustainable management of Louisiana’s coastal wetland forests: problems, constraints, and a new beginning  

SciTech Connect

Over 345,000 ha of forested swamps occur throughout the Mississippi River Deltaic Plain. Natural and anthropogenic changes in hydrology and geomorphology at local and landscape levels have reduced the productivity in many of these coastal wetland forests areas and have caused the complete loss of forest cover in some places. A summary and interpretation of the available science, suggestions for policy change, and a multidisciplinary (multi-responsibility) approach were needed to address these issues [in the context of private land]. In response, the Louisiana Governor's office formed a Coastal Wetland Forest Conservation and Use Science Working Group (SWG) and an associated Advisory Panel to provide the Governor with information and suggestions of strategies for environmental and economic utilization, conservation, and protection of Louisiana's coastal wetland forest ecosystem in the long-term. The process of engaging scientists, resource managers, and other stakeholders in this effort is described, and the recommendations of the SWG are presented relative to forestry practices and the potential for sustainable management of coastal wetland forests.

Successful exploration for hydrocarbons in the Northern Gulf of Mexico basin requires a systematic understanding of hydrocarbon producing trends, sand body geometries and the geologic, engineering and reservoir parameters of the producing sands. This study forms part of the Offshore Atlas project in progress at the University of Texas at Austin, Bureau of Economic Geology, Texas, in co-operation with the U.S. Department of Interior, Minerals Management Service, and the Geological Survey of Alabama, and is aimed at achieving this goal. In this study, 26 chronozones were grouped into 12 sub-groups. The chronozones were defined on the basis of the benthic foraminiferal biostratigraphic zones and were correlated across the Gulf using well log and seismic data and were projected from the Federal offshore into the State waters. The chronozones on each well log in the 22 cross sections constructed from West Cameron area eastward to the Chandeleur, Breton Sound and Main Pass areas, were subdivided as applicable into four depositional groups consisting of aggradational, progradational, transgressive and submarine fan facies based primarily on SP log shapes. In the Louisiana State waters there are 86 fields containing 679 reservoirs. This includes 212 oil, 344 gas, 33 condensate and 90 combination type reservoirs. Total combined cumulative production (1975-1995) is 454,335,217 barrels of oil, 114,327,696 barrels of condensate and 5,436,623,888 thousand cubic feet of gas. Total assigned production shows the progradational facies to be most productive yielding 51.69% oil 93.84% condensate, and 77.47% gas. The aggradational facies sands produced 46.96% oil, 1.70% condensate and 17.78%. gas. The submarine fan facies yielded 1.21% oil, 4.45% condensate, and 6.74% gas. Production from the transgressive facies sands was less than 0.2% of the total assigned production of oil, gas and condensate.

Coastal Prairie Restoration Information System: Version 1 (Louisiana)  

USGS Publications Warehouse

The Coastal Prairie Restoration Information System (CPR) is a Microsoft Access database that allows users to query and view data about Louisiana coastal prairie species. Less than 0.1% of Louisiana's coastal prairie vegetation remains in a relatively undisturbed condition. Encompassing as much as 1 million hectares of land, coastal prairie is a hybrid of coastal wetlands and tall grass prairie. Over 550 plant species have been identified in Louisiana's coastal prairies to date. Efforts to conserve and restore this endangered ecosystem are limited by the ability of workers to identify and access knowledge about this diverse group of plants. In this database, a variety of data are provided for each of 650 coastal prairie species in Louisiana. The database was developed at the U.S. Geological Survey National Wetlands Research Center by Larry Allain, with software development by Myra Silva. Additional funding was provided by the biology department of the University of Louisiana at Lafayette (ULL), the ULL Center for Environmental and Ecological Technology, and the National Science Foundation.

Ghost fishing activity in derelict blue crab traps in Louisiana.  

PubMed

Derelict crab traps impact the coastal ecosystem through continued catch of target species and species of conservation, economic, or recreational importance. During volunteer-supported crab trap cleanups in 2012 and 2013, we quantified ghost fishing activity in derelict crab traps in coastal Louisiana through a citizen scientist program. Volunteers removed 3607 derelict traps during these events, and over 65% of traps analyzed by citizen scientists were actively ghost fishing. Additionally, volunteers identified 19 species enmeshed in derelict traps, including a combination of fresh and saltwater species. We also detected a significant difference in the number of blue crab in actively ghost fishing derelict traps across removal locations with estimated catches varying between 2.4 and 3.5 crabs/trap. Our instantaneous estimates of ghost fishing activity are greater than those previously thought in Louisiana, further justifying current derelict crab trap prevention and removal extension and outreach programs in Louisiana and throughout the Gulf of Mexico.

Hurricane Influences on Vegetation Community Change in Coastal Louisiana  

USGS Publications Warehouse

The impacts of Hurricanes Katrina and Rita in 2005 on wetland vegetation were investigated in Louisiana coastal marshes. Vegetation cover, pore-water salinity, and nutrients data from 100 marsh sites covering the entire Louisiana coast were sampled for two consecutive growing seasons after the storms. A mixed-model nested ANOVA with Tukey's HSD test for post-ANOVA multiple comparisons was used to analyze the data. Significantly (p<0.05) lower vegetation cover was observed within brackish and fresh marshes in the west as compared to the east and central regions throughout 2006, but considerable increase in vegetation cover was noticed in fall 2007 data. Marshes in the west were stressed by prolonged saltwater logging and increased sulfide content. High salinity levels persisted throughout the study period for all marsh types, especially in the west. The marshes of coastal Louisiana are still recovering after the hurricanes; however, changes in the species composition have increased in these marshes.

Space radar image of New Orleans, Louisiana  

NASA Technical Reports Server (NTRS)

This image of the area surrounding the city of New Orleans, Louisiana in the southeastern United States demonstrates the ability of multi-frequency imaging radar to distinguish different types of land cover. The dark area in the center is Lake Pontchartrain. The thin line running across the lake is a causeway connecting New Orleans to the city of Mandeville. Lake Borgne is the dark area in the lower right of the image. The Mississippi River appears as a dark, wavy line in the lower left. The white dots on the Mississippi are ships. The French Quarter is the brownish square near the left center of the image. Lakefront Airport, a field used mostly for general aviation, is the bright spot near the center, jutting out into Lake Pontchartrain. The image was acquired by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) during orbit 39 of space shuttle Endeavour on October 2, 1994. The area is located at 30.10 degrees north latitude and 89.1 degrees west longitude. The area shown is approximately 100 kilometers (60 miles) by 50 kilometers (30 miles). The colors in this image were obtained using the following radar channels: red represents the L-band (horizontally transmitted and received); green represents the C-band (horizontally transmitted and received); blue represents the L-band (vertically transmitted and received). The green areas are primarily vegetation consisting of swamp land and swamp forest (bayou) growing on sandy soil, while the pink areas are associated with reflections from buildings in urban and suburban areas. Different tones and colors in the vegetation areas will be studied by scientists to see how effective imaging radar data is in discriminating between different types of wetlands. Accurate maps of coastal wetland areas are important to ecologists studying wild fowl and the coastal environment.

Wave damping across the Louisiana shelf  

NASA Astrophysics Data System (ADS)

Ocean surface gravity waves are attenuated as they propagate across muddy regions of continental shelves and coastal areas. However, the details of the wave-mud interaction process are not understood well, and thus it is unclear how these effects can best be represented in operational wave and circulation models. To improve our understanding of the effect of a muddy seafloor on wave dynamics, and to assess our ability to represent these effects in a conventional third-generation wave model, we have analyzed a new data set collected on the muddy Louisiana coast in the spring of 2008. Waves were observed for two months at 32 locations along a 25 km transect between 13- and 2-m water depth for a wide range of wind and wave conditions. Of these sensors, two arrays aligned perpendicular to the coast will be of particular interest. To investigate the effects of mud on the nearshore wave energy balance, the SWAN wave model is used to hindcast the observational period, using a standard JONSWAP bottom friction term for wave-bottom interaction. Wind fields are taken from observations (4km offshore), including corrections to account for surface roughness transitions near the land-ocean interface. We will compare observations and model predictions of significant wave heights, energy flux, and wave spectra for the entire period that observations are available, in conditions ranging from swell to shallow-water fetch-limited wave growth. This research is supported by the Office of Naval Research and a National Security Science and Engineering Faculty Fellowship.

Legal Considerations in End-of-Life Decisionmaking in Louisiana  

PubMed Central

End-of-life directives are among the most difficult decisions that a patient or a patient's family makes because of the many moral, ethical, legal, and practical considerations. This article addresses the basic legal framework in Louisiana for end-of-life directives. Although Louisiana law provides a framework for addressing end-of-life issues, the law does not dictate outcomes or decisions. The law is often the refuge of last resort, providing unsatisfactory results. End-of-life care decisions are generally most productive when they are based on discussions between patients, their families, and their care team regarding the patient's wishes.

Summary of the railroad system of Texas: A component of the state and national transportation infrastructure. Project summary report, September 1997--August 1998  

SciTech Connect

Railroads continue to play an important role in moving domestic and international freight through Texas, contributing to economic growth in the state. This study addresses the potential for implementing a rail planning process in the Texas Department of Transportation. In order to accomplish this, successful rail planning processes at other US departments of transportation were evaluated and exemplary programs identified. Three reports were published addressing a variety of findings. The first, published by the Lyndon B. Johnson School of Public Affairs at the University of Texas at Austin, provides an overview and examination of 32 state rail policies, plans, and programs for both passenger and freight traffic. The second report, also published by the Lyndon B. Johnson School of Public Affairs at the University of Texas at Austin, provides information on exemplary state rail programming and planning based on case studies of California, Florida, North Carolina, and the state of Washington. The third report, published by the Texas Transportation Institute at Texas A and M University, provides (1) a framework for rail planning in Texas, (2) identification of current rail issues in Texas, (3) a case study on urban rail rationalization, and (4) a characterization of the rail system in Texas. In each report, detailed appendices are provided to complement the findings and recommendations. In this project summary report, an implementation schedule is recommended to institute rail planning in the Texas Department of Transportation.

Reconnaissance of Macondo-1 well oil in sediment and tarballs from the northern Gulf of Mexico shoreline, Texas to Florida  

USGS Publications Warehouse

Hydrocarbons were extracted and analyzed from sediment and tarballs collected from the northern Gulf of Mexico (nGOM) coast that is potentially impacted by Macondo-1 (M-1) well oil. The samples were analyzed for a suite of diagnostic geochemical biomarkers. Aided by multivariate statistical analysis, the M-1 well oil has been identified in sediment and tarballs collected from Louisiana, Alabama, Mississippi, and Florida. None of the sediment hydrocarbon extracts from Texas correlated with the M-1 well oil. Oil-impacted sediments are confined to the shoreline adjacent to the cumulative oil slick of the Deepwater Horizon oil spill, and no impact was observed outside of this area.

Geomorphic processes active in the Southwestern Louisiana Canal, Lafourche Parish, Louisiana  

NASA Technical Reports Server (NTRS)

The geomorphological changes causing the destruction of the banks of the Southwestern Louisiana Canal are studied by means of field work, laboratory analyses, and infrared color imagery interpretation. Turbulence and flow patterns are mapped, and related to erosion and sediment deposition processes. The accelerated erosion rate of the last decade is discussed, with two causative factors cited: (1) development of faster boats, increasing bank and bottom erosion, and (2) a subsequently larger tidal influx, with greater erosive ability. The physical properties of the canal bank materials are also analyzed. It is concluded that channel erosion progressively increases, with no indications of stabilization, until they merge with other waterways and become indistinguishable from natural water bodies.

MISR Scans the Texas-Oklahoma Border  

NASA Technical Reports Server (NTRS)

These MISR images of Oklahoma and north Texas were acquired on March 12, 2000 during Terra orbit 1243. The three images on the left, from top to bottom, are from the 70-degree forward viewing camera, the vertical-viewing (nadir) camera, and the 70-degree aftward viewing camera. The higher brightness, bluer tinge, and reduced contrast of the oblique views result primarily from scattering of sunlight in the Earth's atmosphere, though some color and brightness variations are also due to differences in surface reflection at the different angles. The longer slant path through the atmosphere at the oblique angles also accentuates the appearance of thin, high-altitude cirrus clouds.

On the right, two areas from the nadir camera image are shown in more detail, along with notations highlighting major geographic features. The south bank of the Red River marks the boundary between Texas and Oklahoma. Traversing brush-covered and grassy plains, rolling hills, and prairies, the Red River and the Canadian River are important resources for farming, ranching, public drinking water, hydroelectric power, and recreation. Both originate in New Mexico and flow eastward, their waters eventually discharging into the Mississippi River.

A smoke plume to the north of the Ouachita Mountains and east of Lake Eufaula is visible in the detailed nadir imagery. The plume is also very obvious at the 70-degree forward view angle, to the right of center and about one-fourth of the way down from the top of the image.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

Distribution and characterization of Heterobilharzia americana in dogs in Texas.  

PubMed

Heterobilharzia americana is a trematode parasite (family Schistosomatidae) that infects a wide range of wild mammalian hosts. Canine cases have been reported in the Gulf coast and south Atlantic states, Kansas, and Oklahoma. A total of 238 canine H. americana cases in Texas were retrospectively collected for a period of approximately 22 years from case records at the Texas Veterinary Medical Diagnostic Laboratory and the Veterinary Medical Teaching Hospital pathology service, diagnostic parasitology service, and Gastrointestinal Laboratory at Texas A&M University College of Veterinary Medicine. Of these cases, 26 patients had 1-2 repeat positive tests for a total of 268 positive tests (26 biopsies, 39 necropsies, 160 fecal examinations, and 43 PCR). Multiple dogs were infected in 12 households. Cases were distributed primarily in the eastern region of Texas in 42 of 254 counties. Cases were seen as far west as Kerr county and in counties bordering Oklahoma, Louisiana, Mexico, and the Gulf of Mexico. The median dog age was 5.6 years (2.7 months to 17.2 years) and the median weight was 20.5kg (1-61.6kg). All American Kennel Club (AKC) breed groups were represented (n=186): crossbred (20%), herding (17.8%), sporting (16.1%), toy (10.8%), hounds (10.8%), working (10.1%), terrier (8.5%), non-sporting (4.9%), and miscellaneous (1%). No seasonal pattern of diagnosis was apparent. Clinical signs reported (n=90) were diarrhea (67%), weight loss (38%), anorexia/hyporexia (27%), vomiting (22%), hematochezia (20%), lethargy (17%), polyuria/polydipsia (6%), and collapse (3%). In 39 necropsy cases, trematode eggs were identified by histopathology in the small intestine (84%), liver (84%), large intestine (39%), pancreas (35%), lung (9%), lymph node (8%), spleen (4%), and stomach (3%). Adult parasites were identified histologically in four cases. Granulomatous inflammation associated with the eggs was the most commonly reported histopathologic change. Other changes reported were fibrosis, pigment in macrophages, and organ mineralization. Glomerulonephritis was identified in four cases. Of 20 necropsy cases where death was attributable to H. americana infection, only one case was diagnosed ante mortem. Eleven of these dogs were examined by a veterinarian but H. americana was included as a differential diagnosis in only two cases. Reported differential diagnoses included ethylene glycol toxicity, cholecalciferol toxicity, lymphoma, and pancreatitis. These data indicate that this parasite is more widely distributed and more common than is generally recognized. Increased awareness may aid in more diagnoses and timely therapy. PMID:24746236

Coastal change analysis program implemented in Louisiana  

USGS Publications Warehouse

Landsat Thematic Mapper images from 1990 to 1996 and collateral data sources were used to classify the land cover of the Mermentau River Basin (MRB) within the Chenier Plain of coastal Louisiana. Landcover classes followed the definition of the National Oceanic and Atmospheric Administration's Coastal Change Analysis Program; however, classification methods had to be developed as part of this study for attainment of these national classification standards. Classification method developments were especially important when classes were spectrally inseparable, when classes were part of spatial and spectral continuums, when the spatial resolution of the sensor included more than one landcover type, and when human activities caused abnormal transitions in the landscape. Most classification problems were overcome by using one or a combination of techniques, such as separating the MRB into subregions of commonality, applying masks to specific land mixtures, and highlighting class transitions between years that were highly unlikely. Overall, 1990, 1993, and 1996 classification accuracy percentages (associated kappa statistics) were 80% (0.79), 78% (0.76), and 86% (0.84), respectively. Most classification errors were associated with confusion between managed (cultivated land) and unmanaged grassland classes; scrub shrub, grasslands and forest classes; water, unconsolidated shore and bare land classes; and especially in 1993, between water and floating vegetation classes. Combining cultivated land and grassland classes and water and floating vegetation classes into single classes accuracies for 1990, 1993, and 1996 increased to 82%, 83%, and 90%, respectively. To improve the interpretation of landcover change, three indicators of landcover class stability were formulated. Location stability was defined as the percentage of a landcover class that remained as the same class in the same location at the beginning and the end of the monitoring period. Residence stability was defined as the percent change in each class within the entire MRB during the monitoring period. Turnover was defined as the addition of other landcover classes to the target landcover class during the defined monitoring period. These indicators allowed quick assessment of the dynamic nature of landcover classes, both in reference to a spatial location and to retaining their presence throughout the MRB. Examining the landcover changes between 1990 to 1993 and 1993 to 1996, led us to five principal findings: (1) Landcover turnover is maintaining a near stable logging cycle, although the locations of grassland, scrub shrub, and forest areas involved in the cycle appeared to change. (2) Planting of seedlings is critical to maintaining cycle stability. (3) Logging activities tend to replace woody land mixed forests with woody land evergreen forests. (4) Wetland estuarine marshes are expanding slightly. (5) Wetland palustrine marshes and mature forested wetlands in the MRB are relatively stable.

Topographic Effects on Soil Organic Carbon in Louisiana Watersheds  

NASA Astrophysics Data System (ADS)

Terrestrial carbon storage is influenced by a number of environmental factors, among which topographic and geomorphological features are of special significance. This study was designed to examine the relationships of soil organic carbon (SOC) density to various terrain parameters and watershed characteristics across Louisiana, USA. A polygon data set of 484 watersheds and 12 river drainage basins for Louisiana was used to form the landscape units. SOC densities were calculated for each soil map unit using the State Soil Geographic (STATSGO) database. Average drainage densities and average slopes at watershed and basin scales were quantified with the 1:24 K Digital Elevation Models (DEM) data, and the Louisiana hydrographic water features. Correlation and regression analyses were performed to determine relationships among drainage density, slope, elevation, and SOC. The study found an average watershed drainage density of 1.6 km/km2 and an average watershed slope of 2.9 degrees in Louisiana. The results revealed that SOC density at both watershed and basin scales was closely related to drainage density, slope, and elevation. SOC density was positively correlated with watershed drainage density, but negatively correlated with watershed slope gradient and elevation. Regression models were developed for predicting SOC density at watershed and basin scales, obtaining regression coefficients ( r 2) ranging from 0.43 to 0.83. The study showed that estimation of SOC at watershed and drainage basin scales combining DEM data can be a feasible approach to improve the understanding of the relationships among SOC, topographic, and geomorphological features.

NASA, Remote Sensing and Archaeology: An Example from Southeast Louisiana  

NASA Technical Reports Server (NTRS)

NASA Stennis Space Center, located in Mississippi, USA, undertook an archaeological survey of the southeastern Louisiana marshes beginning in 2003. Progress on this activity was severely hampered by the 2005 hurricane season when both Katrina and Rita devastated the study area. In 2008, the NASA team reinitiated the analysis of the project data and that work continues today. The project was conducted initially in partnership with the U.S. Army, Corps of Engineers New Orleans District and Tulane University. NASA and its partners utilized a wide variety of satellite and airborne remote sensing instruments combined with field verification surveys to identify prehistoric archeological sites in the Southeastern Louisiana delta, both known and still undiscovered. The main approach was to carefully map known sites and use the spectral characteristics of these sites to locate high probability targets elsewhere in the region. The archaeological activities were conducted in support of Coast 2050 whose stated goals is to sustain and restore a coastal ecosystem that supports and protects the environment, economy and culture of southern Louisiana. As the Coast 2050 report states: [T]he rate of coastal land loss in Louisiana has reached catastrophic proportions. Within the last 50 years, land loss rates have exceeded 40 square miles per year, and in the 1990's the rate has been estimated to be between 25 and 35 square miles each year. This loss represents 80% of the coastal wetland loss in the entire continental United States.

Currents and water characteristics around the West Flower Garden Bank. [West Flower Garden Bank, coral reef, Texas continental shelf  

SciTech Connect

The West Flower Garden Bank is a coral reef on the Texas Continental shelf. The corals on the bank are vulnerable to sediment contamination and to excess turbidity in the overlying water column. Concern for the environmental impact on this and other banks in the region exposed to nearby hydrocarbon production prompted the Bureau of Land Management to fund a data collection effort on the Texas/Louisiana shelf which provided the data analyzed here. Data analyzed includes profiles of velocity, temperature and salinity taken around the Bank in Oct., 1980 and March, 1981. Fixed current meter moorings and a dye experiment conducted in the bottom boundary layer provided additional input. The data reveals a very complicated flow regime around the bank, with some intensification of flow around and over the bank but no movement of water from the bottom of the surrounding shelf up onto the bank.

Chagas Disease Risk in Texas  

PubMed Central

Background Chagas disease, caused by Trypanosoma cruzi, remains a serious public health concern in many areas of Latin America, including México. It is also endemic in Texas with an autochthonous canine cycle, abundant vectors (Triatoma species) in many counties, and established domestic and peridomestic cycles which make competent reservoirs available throughout the state. Yet, Chagas disease is not reportable in Texas, blood donor screening is not mandatory, and the serological profiles of human and canine populations remain unknown. The purpose of this analysis was to provide a formal risk assessment, including risk maps, which recommends the removal of these lacunae. Methods and Findings The spatial relative risk of the establishment of autochthonous Chagas disease cycles in Texas was assessed using a five–stage analysis. 1. Ecological risk for Chagas disease was established at a fine spatial resolution using a maximum entropy algorithm that takes as input occurrence points of vectors and environmental layers. The analysis was restricted to triatomine vector species for which new data were generated through field collection and through collation of post–1960 museum records in both México and the United States with sufficiently low georeferenced error to be admissible given the spatial resolution of the analysis (1 arc–minute). The new data extended the distribution of vector species to 10 new Texas counties. The models predicted that Triatoma gerstaeckeri has a large region of contiguous suitable habitat in the southern United States and México, T. lecticularia has a diffuse suitable habitat distribution along both coasts of the same region, and T. sanguisuga has a disjoint suitable habitat distribution along the coasts of the United States. The ecological risk is highest in south Texas. 2. Incidence–based relative risk was computed at the county level using the Bayesian Besag–York–Mollié model and post–1960 T. cruzi incidence data. This risk is concentrated in south Texas. 3. The ecological and incidence–based risks were analyzed together in a multi–criteria dominance analysis of all counties and those counties in which there were as yet no reports of parasite incidence. Both analyses picked out counties in south Texas as those at highest risk. 4. As an alternative to the multi–criteria analysis, the ecological and incidence–based risks were compounded in a multiplicative composite risk model. Counties in south Texas emerged as those with the highest risk. 5. Risk as the relative expected exposure rate was computed using a multiplicative model for the composite risk and a scaled population county map for Texas. Counties with highest risk were those in south Texas and a few counties with high human populations in north, east, and central Texas showing that, though Chagas disease risk is concentrated in south Texas, it is not restricted to it. Conclusions For all of Texas, Chagas disease should be designated as reportable, as it is in Arizona and Massachusetts. At least for south Texas, lower than N, blood donor screening should be mandatory, and the serological profiles of human and canine populations should be established. It is also recommended that a joint initiative be undertaken by the United States and México to combat Chagas disease in the trans–border region. The methodology developed for this analysis can be easily exported to other geographical and disease contexts in which risk assessment is of potential value.

Post-glacial Sediment Load and Subsidence in Coastal Louisiana  

NASA Technical Reports Server (NTRS)

Sea level rise in the Gulf of Mexico has occurred at a rate of 1.8-2.2 mm/yr during the 20th century, or nearly the same as observed globally due to combined steric and water mass changes. Tide gauges in coastal Louisiana, however, record a substantially larger rate of rise and while a number of causal mechanisms may be responsible, their specific contribution is poorly understood. Using a realistic viscoelastic Earth model, detailed geologic parameters for south Louisiana and new GPS data, we demonstrate that Holocene sedimentary loading in the Gulf and Mississippi River delta is capable of contributing to 1-8 mm/yr of subsidence over areas of 30-0.75 x 10(exp 3) km(exp 2).

Local sea level change and future of Louisiana coast  

SciTech Connect

The relative elevation of sea and land has been changing through time in response to two fundamentally different groups of factors. Global factors include changes in the volume of the ocean basins owing to tectonic processes and changes in the total amount of ocean water due to glaciation. Local factors include subsidence of continental margins and compaction of recent sediments. Over this century, global sea level (eustatic) appears to have been rising at a rate of 1.2 mm per year. Along the south-central Louisiana coast the land surface appears to be sinking at a rate of about 8 mm per year. Recent global climatic modeling suggests strongly that we are about to enter a period of rapidly accelerating warming due to increased amount of carbon dioxide in the atmosphere. As a consequence, eustatic sea level rise is predicted to accelerate because of both steric expansion of the ocean water and continued melting of polar ice caps. For the next 40 years the eustatic sea level rise may average 10 mm per year. The local relative sea level in coastal Louisiana would therefore rise at about twice its present rate over this time period. The numbers presented above are average value for the Louisiana coastal plain. Local variability in subsidence rate appear to be related to the thickness of Holocene sediments. The highest rates of subsidence are found in the modern Mississippi (birdfoot) delta and in coastal Terrebonne Parish above the late Pleistocene Mississippi trench; in both areas the Holocene section is in excess of 200 m (650 ft) thick. The high rate of local sea level rise along the Louisiana coast makes it imperative that plans for coastal development and protection consider the long-term consequences of sea level change.

Denitrification in coastal Louisiana: A spatial assessment and research needs  

NASA Astrophysics Data System (ADS)

By transforming fixed nitrogen (N) into nitrogen gas, the biochemical processes that support denitrification provide a function critical to maintaining the integrity of ecosystems subjected to increased loading of N from anthropogenic sources. The Louisiana coastal region receives high nitrate (NO 3-) concentrations (> 100 µM) from the Mississippi-Ohio-Missouri River Basin and is also an area undergoing high rates of wetland loss. Ongoing and anticipated changes in the Louisiana coastal region promise to alter biogeochemical cycles including the net rate of denitrification by ecosystems. Projecting what these changes could mean for coastal water quality and natural resources requires an understanding of the magnitude and patterns of variation in denitrification rates and their connection to estuarine water quality at large temporal and spatial scales under current conditions. We compile and review denitrification rates reported in 32 studies conducted in a variety of habitats across coastal Louisiana during the period 1981- 2008. The acetylene inhibition and 15N flux were the preferred techniques (95%); most of the studies used sediment slurries rather than intact sediment cores. There are no estimates of denitrification rates using the N 2/Ar ratio and isotope pairing techniques, which address some of the problems and limitations of the acetylene inhibition and 15N flux techniques. These studies have shown that sediments from estuaries, lakes, marshes, forested wetlands, and the coastal shelf region are capable of high potential denitrification rates when exposed to high NO 3- concentrations (> 100 µM). Maximum potential denitrification rates in experimental and natural settings can reach values > 2500 µmol m 2 h - 1 . The lack of contemporary studies to understand the interactions among critical nitrogen transformations (e.g., organic matter mineralization, immobilization, aquatic plant assimilation, nitrification, nitrogen fixation, dissimilatory nitrate reduction to ammonium (DNRA) and anaerobic ammonium oxidation (annamox) limits our understanding of nitrogen cycling in coastal Louisiana, particularly the role of respiratory and chemolithoautotrophic denitrification in areas undergoing wetland restoration.

Subsurface geology of Louisiana hazardous waste landfills: A case study  

NASA Astrophysics Data System (ADS)

Many hazardous waste sites in the south Louisiana Gulf Coast have been emplaced in sediments of Plio-Pleistocene to Recent age. Because of the fining upward nature of these regressive-transgressive fluvial-deltaic sequences and the purported confining capabilities of the shallow clay layers within them, this area would seem to be ideal for the location of surface waste landfills. However, detailed geologic mapping at a site in southeastern Louisiana documents how the three-dimensional distribution of sediment types and early diagenetic features, both of which were ultimately controlled by depositional history, can increase effective vertical permeability of finegrained sequences. Many bodies of sand that appear to be isolated in standard geotechnical cross sections can be shown to be part of spatially complex three-dimensional distributary networks, with fine-grained sediments representing overbank and backswamp deposits. Some clay layers are actually a composite of thinner clay beds, each subjected to subaerial exposure and the development of secondary porosity related to soil formation. There has been documented leakage of wastes down through the clays, and a recent study indicates that the effective vertical hydraulic conductivity of the clay layers exceeds 10-5 cm s-1, or from one to four orders of magnitude higher than values measured on samples from cores of the same sediment. An understanding of the depositional framework, facies architecture, and diagenetic history of geologic materials underlying waste disposal sites in Louisiana is required for rational development of monitoring and remediation plans.

Origin and structural development of the LaSalle Arch, Louisiana  

SciTech Connect

The LaSalle arch is a basement high separating the Louisiana and Mississippi interior salt basins. Using reflection seismic data, an area located on the southern end of the LaSalle arch was shown to be composed of relict Paleozoic continental crust that was left behind and partially rifted during the breakup of Pangea during the Triassic. Rifting preferentially occurred to the north of a Paleozoic thrust fault nose, and crustal extension took place in a northeast-southwest direction. The LaSalle arch, as seen in post-Triassic stratigraphy, formed by a two-part process. The western limb developed syndepositionally due to differential subsidence, and the eastern limb developed due to relative regional tilting to the east after deposition of the Claibornian Sparta Formation. The LaSalle arch acted as only a minor impediment to sediment transport with a very low relief except during the Tayloran Stage of the Upper Cretaceous. A single truncational unconformity in post-Triassic stratigraphy is present in the Taylora Demopolis Formation, indicating a period of relatively major uplift by the LaSalle arch. This contrast, with the Sabine arch in eastern Texas; the Sabine arch experienced uplift during the Eagle Fordian and Sabinian stages. A recently proposed hypothesis calling for overthrusting in the Western Cordillera as the mechanism for uplift on the Sabine arch cannot explain movement of the LaSalle arch because horizontal stress would predict synchronous uplift of basement highs. A more satisfactory uplift mechanism calls upon lateral heat flow from the mantle as the driving force for uplift.

Red Tide off Texas Coast  

NASA Technical Reports Server (NTRS)

Red tides (algae) bloomed late this summer along a 300-mile stretch of Texas' Gulf Coast, killing millions of fish and shellfish as well as making some people sick. State officials are calling this the worst red tide bloom in 14 years. The algae produces a poison that paralyzes fish and prevents them from breathing. There is concern that the deadly algae could impact or even wipe out this year's oyster harvest in Texas, which usually peaks during the Thanksgiving and Christmas holidays. The red tides were first observed off the Texas coast in mid-August and have been growing steadily in size ever since. Red tides tend to bloom and subside rapidly, depending upon changes in wind speed and direction, water temperature, salinity, and rainfall patterns (as the algae doesn't do as well in fresher water). This true-color image of the Texas Gulf Coast was acquired on September 29, 2000, by the Moderate-resolution Imaging Spectroradiometer (MODIS) flying aboard NASA's Terra spacecraft. The red tide can be seen as the dark reddish discoloration in the ocean running southwest to northeast along the coast. In this scene, the bloom appears to be concentrated north and east of Corpus Christi, just off Matagorda Island. The image was made at 500-meter resolution using a combination of MODIS' visible bands 1 (red), 4 (green), and 3 (blue). The city of Houston can be seen clearly as the large, greyish cluster of pixels to the north and west of Galveston Bay, which is about mid-way up the coastline in this image. Also visible in this image are plumes of smoke, perhaps wildfires, both to the north and northeast of Houston. For more information about red tides, refer to the Texas Red Tide Web site.

Texas prepares to enact an emissions credit system  

SciTech Connect

Texas is pressing ahead with plans to create a market for emissions reduction credits with a program much more comprehensive than those being enacted by the U.S. Government and California. As we get established, we'll know a lot more about emissions reductions, which is the real goal of the program,' says James Dodds, the attorney with the Texas Air Control Board's (TACB) special projects division, charged with developing the program. For now, we are just trying to provide a point of focus.' The centerpiece of the program is a banking rule that would establish two central registries for emission credits, one for volatile organic compounds (VOCs) and the other for nitrogen oxides (NOx). That program is under formal consideration by the TACB. It has been published in the state register, and is open for public comment. Dodds expect the board to adopt the rule in January, and to get the bank going by next spring. Four other projects are also being considered as part of a comprehensive, market-based emissions reduction plan. A community banking task force to provide ways for localities to acquire offset credits for use in economic development is being examined. Alternate rules for NOx are also being developed.

Cores were taken from seven locations in southern Louisiana and analyzed for concentrations of heavy metals. Sedimentation rates for the locations were determined using the /sup 137/Cs dating technique. Correlations of metals with depth were calculated using absolute, aluminum normalized, and iron normalized concentrations. Correlations indicated recent increases at several sites (Lake Palourde, Manchac Pass, and Wax Lake Outlet) for several metals (Pb, Cd, Cr, Ni, Zn) when profiles were normalized to aluminum. Metal profiles from rapidly-accreting areas (Atchafalaya and Four league Bay) did not show historical increases comparable to areas accreting less rapidly (e.g., Wax Lake Outlet, Manchac Pass, and Lake Palourde).

Elimination of bagassosis in Louisiana paper manufacturing plant workers.

The prevalence of bagassosis was investigated in a Louisiana paper mill, which in the past had considerable numbers of workers with the disease. Based on negative clinical histories and the low number of positive serological reactions of the workers' serum with Thermoactinomyces sacchari antigen, it was concluded that bagassosis was no longer present. This was thought to be due to a different method of storage of bagasse, which retards microbial decay and reduces airborne organic dust, and to the increased awareness of plant management resulting in greater safety measures.

Reservoir petroleum geochemistry of Sarita (South Texas), Eugene Island 330 and South Marsh Island 128 (offshore Louisiana) oil fields  

SciTech Connect

Hydrocarbon fluid compositions within three petroleum fields were shown to be heterogeneous in some aspects while appearing to have a common source for each field. However biomarker parameters indicate that three difference sources were respectively responsible for each field accumulation. Visual inspection of whole oil chromatograms, gasoline molecular composition, and quantitative concentrations of biomarkers were used to define the range of fluid chemistries observed. Biomarker compositions and content were nearly identical regardless of depth of production, suggesting that all reservoirs within a field were filled with a common fluid. Fluids in reservoirs of the Sarita and Eugene Island 330 fields were biodegraded to varying degrees in the shallowest sand reservoirs. Hydrocarbon fluids in these two fields were also altered by evaporative fractionation, a phase segregation allowing condensate to occur shallower than oil. Alteration due to evaporative fractionation is related to secondary injection of post mature gas and subsequent remigration up faults. South Marsh Island 128 fluids are in a nearly pristine condition. Whole-oil fingerprints and gasoline composition are specific to a given pay zone of fault block and can be used as a correlation tool. Communication between reservoirs is indicated by a common fluid chemistry, whereas fluid chemistry variations suggest compartmentalized accumulations. The scale examination of fluid chemistry within fields can help define the history of reservoir filling and changes in fluid properties during field development and production.

Expansion of the Strategic Petroleum Reserve, Alabama, Louisiana, Mississippi, and Texas: Draft Environmental Impact Statement. Volume 3, Technical appendices  

SciTech Connect

The proposed action entails the development of a plan for 250 million barrels of new crude oil storage capacity in two Gulf Coast salt domes to expand the Strategic Petroleum Reserve pursuant to Congressional directive (PL 101--383 and PL 101--512). Storage capacity would be developed by solution-mining the salt which would require about two billion barrels of surface water and would generate about two billion barrels of salt brine. The brine would be disposed of primarily by ocean discharge and alternatively by deep underground injection. Crude oil fill and distribution systems would require new pipelines and terminal facilities. This EIS assesses the impacts of construction and operation for the range of alternatives being considered and focuses on oil and brine spill risk and impacts of brine disposal, water and land use, groundwater contamination, hydrocarbon emissions, and involvement with wetlands and floodplains.

Risk assessment for produced water discharges to Louisiana open bays  

SciTech Connect

Potential human health and environmental impacts from discharge of produced water to the Gulf of Mexico concern regulators at the State and Federal levels, environmental interest groups, industry and the public. Current regulations in the United States require or propose azero discharge limit for coastal facilities based primarily on studies performed in low energy,poorly flushed environments. Produced water discharges in coastal Louisiana, however,include a number located in open bays, where potential and impacts are likely to be larger than the minimal impacts associated with offshore discharges, but smaller than those demonstrated in low-energy canal environments. This paper summarizes results of a conservative screening-level health and ecological assessment for contaminants discharged in produced water to open bays in Louisiana, and reports results of a probabilistic human health risk assessment for radium and lead. The initial human health and ecological risk assessments consisted of conservative screening analyses that identified potentially important contaminants and excluded others from further consideration. A more quantitative probabilistic risk assessment was completed for the human health effects of the two contaminants identified in this screen: radium and lead. This work is part of a series of studies on the health and ecological risks from discharges of produced water to the Gulf of Mexico, supported by the United States Department of Energy (USDOE).

The objective of the proposed project is to focus on the applied, rather than basic research emphasizing the design and development, metrology, inspection and testing, and the assembly and production of micron and submicron structures and devices. Also, the objective of the beamline at CAMD would be the fundamental study of processing and analysis technologies, including x-ray lithography, which are important to microstructures fabrication and electronic device development. Based on the analysis in the EA, the DOE has determined that the proposed action does not constitute a major federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act of 1969 (NEPA). Therefore, the preparation of an Environmental Impact Statement is not required.

QTL analysis of floral traits in Louisiana iris hybrids.  

PubMed

The formation of hybrid zones between nascent species is a widespread phenomenon. The evolutionary consequences of hybridization are influenced by numerous factors, including the action of natural selection on quantitative trait variation. Here we examine how the genetic basis of floral traits of two species of Louisiana Irises affects the extent of quantitative trait variation in their hybrids. Quantitative trait locus (QTL) mapping was used to assess the size (magnitude) of phenotypic effects of individual QTL, the degree to which QTL for different floral traits are colocalized, and the occurrence of mixed QTL effects. These aspects of quantitative genetic variation would be expected to influence (1) the number of genetic steps (in terms of QTL substitutions) separating the parental species phenotypes; (2) trait correlations; and (3) the potential for transgressive segregation in hybrid populations. Results indicate that some Louisiana Iris floral trait QTL have large effects and QTL for different traits tend to colocalize. Transgressive variation was observed for six of nine traits, despite the fact that mixed QTL effects influence few traits. Overall, our QTL results imply that the genetic basis of floral morphology and color traits might facilitate the maintenance of phenotypic divergence between Iris fulva and Iris brevicaulis, although a great deal of phenotypic variation was observed among hybrids.

Recent accretion in two managed marsh impoundments in coastal Louisiana  

USGS Publications Warehouse

Recent accretion was measured by the feldspar marker horizon method in two gravity-drained, managed, marsh impoundments and unmanaged reference marshes located on the rapidly subsiding coast of Louisiana. Water level management was designed to limit hydrologic exchange to the managed marsh by regulating the direction and rate of water flows. During a drawdown-flooding water management cycle, the unmanaged reference marshes had significantly higher vertical accretion rates, higher soil bulk density and soil mineral matter content, lower soil organic matter content, and higher rates of organic matter accumulation than the managed marsh. The rate of mineral matter accumulation was higher in both reference marshes, but was significantly higher in only one. Spatial variability in accumulation rates was low when analyzed in one managed marsh site, suggesting a primarily autochthonous source of matter. In contrast, the associated reference marsh apparently received allochthonous material that settled out in a distinct spatial pattern as water velocity decreased. The impoundment marshes experienced an accretion deficit of one full order of magnitude (0.1 vs. 1.0 m/yr) based on comparison of accretion and sea level rise data, while the unmanaged reference marshes experienced a five-fold smaller deficit or no deficit. These data suggest that the gravity-drained impoundments likely have a shorter life expectancy than the reference marshes in the rapidly subsiding Louisiana coast.

The Louisiana ACES student-built BalloonSat program  

NASA Astrophysics Data System (ADS)

A major concern of many aerospace industries and space agencies worldwide is the continuing decrease in undergraduate student enrollment and graduation from aerospace and closely related degree programs. With a decreasing number of new aerospace workforce candidates, expanding or sustaining our exploration of the universe over the coming decades could be at risk. In Louisiana, we have developed the Aerospace Catalyst Experiences for Students (ACES) program to address this issue by attracting new students to aerospace-related programs and providing interdisciplinary training on how to design, build, and manage aerospace payloads. Based upon the National Space Grant Student Satellite Program "Crawl, Walk, Run, Fly!" methodology, ACES closely ties cross-discipline content knowledge with extensive hands-on experiences to instill skills that are then applied by the students to design, document, build, test, and operate a small balloon-borne scientific payload. The ACES concept was initially piloted during 2002-2003 and now includes a semi-formal "Student Ballooning Course", five Louisiana institutions and serves ˜45 students.

Seasonal transmission of gastrointestinal parasites of equids in southern Louisiana.  

PubMed

Parasite-naive pony foals were used as sentinels to monitor transmission of gastrointestinal parasites of equids in Louisiana during 4 seasons of the year. Two annual periods were studied, 1988-1989 and 1992-1993. Two or 3 foals each season were turned out to graze a contaminated pasture along with resident parasitized mares and their foals. After a grazing period of 8 wk, sentinel ponies were held in a parasite-free box stall for a period of 6 wk to allow parasites to develop, thus enhancing the evaluation of hypobiotic stages. Following this holding period, necropsies were performed for complete parasite recoveries. Data show that transmission of large and small strongyles occurs during all seasons in southern Louisiana, with highest levels of transmission occurring in the winter and only minimal transmission taking place in the summer. Numbers of mucosal cyathostomes, as well as total cyathostome numbers, were highest in the winter, and luminal cyathostome numbers were highest in the spring. Transmission of Anoplocephala perfoliata and Parascaris equorum occurred during all seasons of the year, although numbers of P. equorum were reduced in spring 1989 and 1993. Gasterophilus intestinalis instars were recovered from fall and winter sentinels only. Oxyuris equi L4 were found all seasons 1 yr, but only during the fall and winter of the final year.

Learning from California`s QF auction  

SciTech Connect

California`s 1993 qualifying facility (QF) auction dramatically illustrates problems that can be encountered in structuring auctions for electric utility solicitations of supply-side resources from qualifying cogeneration and small power production facilities. In the 1993 California QF auction, three California utilities were to select QFs that would be awarded long-term purchased-power contracts. The auction produced some unexpected outcomes that could potentially cost the utilities and their customers tens of millions of dollars per year. A year after the auction was held, the parties were still attempting to revise contracts, or even rebid a portion of the auction. And all of this effort may come to naught, depending upon what happens now that the Federal Energy Regulatory Commission has struck down the auction process under California`s Biennial Resource Plan Update, claiming that it violates the Public Utility Regulatory Policies Act (PURPA) by using an improper method to calculate avoided costs. A study of the California QF auction illustrates yet again that the devil is in the details. And the stakes will only rise farther as regulators in other states rely more on auctions to open up the electric industry to further competition.

CHAMBERS FERRY ROADLESS AREA, TEXAS.  

USGS Publications Warehouse

A geologic and geochemical investigation of the Chambers Ferry Roadless Area, Texas was conducted. The area has probable mineral-resource potential for oil and gas and for lignite. No metallic or additional energy resources were identified in the investigation. Detailed analyses of well logs from the vicinity of the Chambers Ferry Roadless Area, in conjunction with seismic data, are necessary to determine if the subsurface stratigraphy and structure are favorable for the accumulation of oil and gas. A shallow drilling program involving coring on a close-space grid is necessary for determination of the rank and continuity of seams of lignitic sediments in the area.

Louisiana Wetland Monitoring Using TOPEX/POSEIDON Altimetry  

NASA Astrophysics Data System (ADS)

Conventional satellite radar altimetry is designed to observe ocean topography and significant technological advance has enabled our capability to measure sea level change, ice sheet elevation and sea ice freeboard height changes, hydrologic changes for large inland lake and rivers, and potentially land deformation. Wide- swath altimetry or interferometric altimetry onboard proposed and planned platforms are anticipated to significantly improve the spatial resolution of observations over ocean, land water, and ice surfaces. Coastal estuaries and wetlands play important roles in ecological environments. They not only provide habitat for thousands of aquatic/terrestrial plant and animal species but also control floods and storm surges by absorbing and reducing the velocity of storm water. Regional measurement of wetland water level changes from space is essential for hydrological studies. To our knowledge, there have been no reported successful attempts to use Ku-band altimetry for this purpose, especially over wetlands with seasonally varying vegetations. Here we demonstrate the use of the pulsed-limited radar altimeter (TOPEX), for the potential monitoring of wetland water level changes. The specific study regions are over the vegetated wetland in Louisiana. In addition to the retracking of Ku-band radar waveforms and generate a water level change time series over Louisiana wetland, we study the effect of media corrections, including the ionosphere and wet troposphere delays which are largely not applied for inland hydrological studies using altimetry. We find that most of the TOPEX waveform responses over the study region are specular or narrow-peaked, and we have tested various retrackers including the conventional OCOG, threshold, and the modified threshold algorithms which result in a decadal (1992-2002) height time series over several specific regions of the Louisiana wetland. It is found that the use of various corrections including wet troposphere delays computed from models (FMO/ECMWF) and DORIS ionosphere delays reduces variance of the resulting wetland water level measurements. The result of the study is anticipated to have an impact on the use of wide-swath radar altimetry for studies of hydrologic processes in world's wetlands.

Gas-rich sediment and coastal wetland loss in Louisiana  

SciTech Connect

High rates of wetland loss in southern Louisiana provide the impetus for examining the role that trapped, biogenic gases play in regulating subsidence of coastal areas. A significant cause for wetland loss in this region is relative sea-level rise produced by sediment-volume reduction. Dewatering, grain reorientation and packing, and oxidation of organic-rich sediments are thought to be the main processes for volume loss. It is argued that natural and anthropogenic causes for sediment degasification play a critical role in sediment-volume reduction. Compressional wave velocities were measured at 34 sites in both the abandoned (Holocene) and modern parts of the Mssissippi Delta. A low-frequency source (<200 Hz) was used to maximize sound-wave dispersion caused by interstitial gas bubbles. Compressional wave velocities measured at low frequencies relative to the gas-bubble resonant-frequency undergo maximum change from the velocity for a gas-free sediment.

West Nile Virus-infected Mosquitoes, Louisiana, 2002  

PubMed Central

Human cases of West Nile virus (WNV) disease appeared in St. Tammany and Tangipahoa Parishes in southeastern Louisiana in June 2002. Cases peaked during July, then rapidly declined. We conducted mosquito collections from August 3 to August 15 at residences of patients with confirmed and suspected WNV disease to estimate species composition, relative abundance, and WNV infection rates. A total of 31,215 mosquitoes representing 25 species were collected by using primarily gravid traps and CO2-baited light traps. Mosquitoes containing WNV RNA were obtained from 5 of 11 confirmed case sites and from 1 of 3 sites with non-WNV disease. WNV RNA was detected in 9 mosquito pools, including 7 Culex quinquefasciatus, 1 Cx. salinarius, and 1 Coquillettidia perturbans. Mosquito infection rates among sites ranged from 0.8/1,000 to 10.9/1,000. Results suggest that Cx. quinquefasciatus was the primary epizootic/epidemic vector, with other species possibly playing a secondary role.

Chronostratigraphy of Plio-Pleistocene sequences, offshore Louisiana  

SciTech Connect

Plio-Pleistocene cool stages correlate with sequence boundaries in the Gulf of Mexico, offshore Louisiana. The cool/warm stages are defined by planktonic foram assemblages in the Vema 16-205 core in the eastern tropical Atlantic. The mean duration of each climatic stage was 230,000 years. These climatic stages were incorporated into a composite standard section with oxygen isotope events, planktonic foraminiferal and nannofossil datums, and magnetostratigraphic events from oceanic core holes: DSDP 502 in the Columbia basin, Caribbean; DSDP 552 on the Rockall Plateau, northeast Atlantic; DSDP 572C in the equatorial Pacific; Vema 28 core 219 on the Solomon Rise, west Pacific; and the Eureka 57 core 135 in DeSoto Canyon, offshore Florida. The oxygen isotope events and the paleontologic datums were identified in two exploration wells in the Green Canyon block, offshore Louisiana, and correlated with seismic sequence boundaries. Iterative graphic correlation with the composite standard refines the positions of the tops of the isotope events where data noise makes the pick equivocal providing a precise, high-resolution correlation tool. Each oxygen isotope event represents approximately 31,000 years. The sequences in the Green Canyon area are from 300 m to 800 m thick, and were deposited at rates from 800 to 1500 cm/ka. The duration of the hiatuses at the sequence boundaries range from 27,000 to 200,000 years. These seismic/depositional sequences were deposited during the alter parts of the cool stage and the warm climates, which indicate rising sea level to highstand. The ages of the sequence boundaries are approximately 500,000 years, 900,000 years, 1.5 Ma, 2.0 Ma, 2.7 Ma, 3.0 Ma, and 3.75 Ma.

Depositional history of Louisiana-Mississippi outer continental shelf  

USGS Publications Warehouse

A geological study was undertaken in 1981 in the Louisiana-Mississippi outer continental shelf for the Bureau of Land Management. The study included a high-resolution seismic reflection survey, surficial sediment sampling and surface current drifter sampling. Approximately 7100 sq km of the Louisiana-Mississippi shelf and upper slope were surveyed. The sea floor of the entire area is relatively smooth except for occasional areas of uplift produced by diapiric intrusion along the upper slope. Characteristics of the topography and subsurface shelf sediments are the result of depositional sequences due to delta outbuilding over transgressive sediments with intervening periods of erosion during low sea level stands. Little evidence of structural deformation such as faults, diapirs, and shallow gas is present on the shelf and only a few minor faults and scarps are found on the slope. Minisparker seismic records in combination with air gun (40 and 5 cu in) and 3.5-kHz subbottom profile records reveal that seven major stages of shelf development have occurred since the middle Pleistocene. The shelf development has been controlled by the rise and fall of sea level. These stages are defined by four major unconformities, several depositions of transgressive sediments, sequences of river channeling and progradational delta deposits. Surficial sediment sample and seismic records indicate tat the last major depositional event was the progradation of the St. Bernard Delta lobe. This delta lobe covered the northwestern and central regions. Surficial sediments in most of the study area are the product of the reworking of the San Bernard Delta lobe and previous progradations.

Multiple Stressors: Lessons from Louisiana Coastal Waters (Invited)  

NASA Astrophysics Data System (ADS)

Coastal Louisiana is a Mississippi River-dominated landscape driven by the long-term (millennia) and short-term (decades to hundreds of years) changes in materials flux, nature and human activities. The results are a highly productive coastal landscape and nearshore coastal waters that support rich natural and non-renewable resources. The ecosystem and socio-economic systems are intimately linked. Several factors have led to the demise of many of the healthy features of this coastal system, including long-term changes in the landscape of the Mississippi River basin watershed, alterations to the structure and flow of the Mississippi River and its tributaries, coastal landscape alterations leading to loss of productive marshes and protective barrier islands, increases in nitrogen and phosphorus loads to the coastal ocean and their detrimental effects, and reduction in the sediments delivered by the river. Increases in population and extraction of living resources and oil and gas reserves continue to drive many actions taken in the coastal landscape and waters. As a result, Louisiana is in a state of major disrepair (to be charitable) and needs thoughtful consideration of restoration actions taken in the river basin and within the coastal landscape. The first thought is to cause no further harm. The second is to proceed acknowledging that human and natural forces (particularly climate change, rising sea level and changing global economies) must be taken into account. Thirdly, a broader consideration of the river basin and coastal landscapes, their interconnectivity, and ecosystem health and social welfare must be taken into account.

Benthic community structure and composition in sediment from the northern Gulf of Mexico shoreline, Texas to Florida  

USGS Publications Warehouse

From April 20 through July 15, 2010, approximately 4.93 million barrels of crude oil spilled into the Gulf of Mexico from the British Petroleum Macondo-1 well, representing the largest spill in U.S. waters. Baseline benthic community conditions were assessed from shoreline sediment samples collected from 56 stations within the swash zone (for example, sample depth ranged from 0 to 1.5 feet) along the northern Gulf of Mexico coastline. These sites were selected because they had a high probability of being impacted by the oil. Cores collected at 24 stations contained no sediment infauna. Benthic community metrics varied greatly among the remaining stations. Mississippi stations had the highest mean abundances (38.9 ± 23.9 individuals per 32 square centimeters (cm2); range: 0 to 186), while Texas had the lowest abundances, 4.9 ± 3 individuals per 32 cm2 (range: 0 to 25). Dominant phyla included Annelida, Arthropoda, and Mollusca, but proportional contributions of each group varied by State. Diversity indices Margalef's richness (d) and Shannon-Wiener diversity (H') were highest at Louisiana and Mississippi stations (0.4 and 0.4, for both, respectively) and lowest at Texas (values for both indices were 0.1 ± 0.1). Evenness (J') was low for all the States, ranging from 0.2 to 0.3, indicating a high degree of patchiness at these sites. Across stations within a State, average similarity ranged from 11.1 percent (Mississippi) to 41.1 percent (Louisiana). Low within-state similarity may be a consequence of differing habitat and physical environment conditions. Results provide necessary baseline information that will facilitate future comparisons with post-spill community metrics.

Stewardship of the public lands in Texas  

SciTech Connect

The Texas General Land Office (TGLO) is a constitutional agency with the responsibility of managing over 22 million acres of public land, including 13.5 million mineral acres. From the panhandle of Texas to the three marine league line in the Gulf of Mexico, the diversity of both the Texas environment and our mineral ownership provides challenges to the management of our valuable public lands and natural resources. Lease provisions, statutory requirements and administrative policies are continually discussed and refined within our agency. The environmental and economic vitality of state lands are also given equal focus and consideration.

Genetic variation in black bears in Arkansas and Louisiana using microsatellite DNA markers  

USGS Publications Warehouse

In the 1950s and 1960s, translocation projects reintroduced black bears (Ursus americanus) from Minnesota and Manitoba to Arkansas and Louisiana. Today, several geographically disconnected populations exist in Arkansas and Louisiana, but their origins are unclear. Some populations may represent a separate subspecies, U. a. luteolus, which is federally protected. We characterized 5 microsatellite loci in 5 isolated populations in Arkansas and Louisiana and compared them with genotypes from Minnesota. Our data indicate that bears of the Ozark and Ouachita mountains of Arkansas, an inland area of Louisiana, and those of Minnesota are similar in overall genetic diversity and allele frequencies, consistent with these populations being wholly or mostly descended from bears from the reintroduction programs. In contrast, bears from southeastern Arkansas and the coastal region of Louisiana genetically are more restricted and homogeneous. Because they exhibit a limited set of genotypes found in the other black bear populations, they represent isolated fragments of a single North American black bear population. Furthermore, genetic distance estimates indicate that the bears in southeastern Arkansas are more genetically distinct from bears in Louisiana, which are currently federally protected.

A predictive model for satellite-derived phytoplankton absorption over the Louisiana shelf hypoxic zone: Effects of nutrients and physical forcing  

NASA Astrophysics Data System (ADS)

We investigated environmental forcing mechanisms of phytoplankton absorption near the Mississippi River delta using multiyear satellite data. An algorithm for the phytoplankton absorption coefficient (aph) was developed from in situ measurements and applied to ocean color imagery. We employed a suite of chemical and physical forcing variables, including surface currents. For satellite-derived aph time series (2002-2004), correlation and stepwise regression analyses revealed the most important forcing variables of aph on the Louisiana shelf. Areally, Mississippi River discharge and nitrate concentration ([NO3]) were the two most important predictors of aph over the hypoxic zone (defined by its maximum extent). River discharge was important in a band stretching from the Mississippi River delta to the Louisiana-Texas border. Riverine [NO3] and wind magnitude best predicted aph in nearshore waters, and solar radiation and SST were most important farther offshore over the hypoxic zone, indicating upwelled nutrient sources to phytoplankton. A multiple linear regression model performed well in resolving seasonal and interannual aph variability in model development years (2002-2004) (mean error of 18%, over all pixels and months) and in predicting shelf-wide aph patterns in 2005 (mean error of 32%). Our results strongly suggest that in recent years, stratification and vertical mixing, in addition to riverine [NO3], play a primary role in regulating phytoplankton biomass over the hypoxic zone. As well, a springtime model experiment showed that aph over the hypoxic zone can differ by an average absolute 37% from its average scenario owing to changes solely in environmental variables other than NO3 flux.

Selenium availability in Texas: possible clinical significance  

SciTech Connect

In light of recent reports that have indicated that selenium is an essential micronutrient and possible natural cancer inhibitor, data on the geographic distributions of selenium in Texas were gathered and compared with the distribution of age-adjusted cancer mortality rates. We considered concentrations of selenium measured in ground and surface water to be indicators of its presence in rocks, soil, and locally grown crops. Texas water sources were found to be poor in selenium, except for the Panhandle and the West Texas regions, where soil consists of erosion products from the selenium-rich Rocky Mountains. In general, lower cancer mortality was observed for the selenium-rich regions of Texas compared with cancer mortality for the selenium poor regions. Even though the risks from cancer-provoking factors also differed geographically, the observed pattern was sufficiently suggestive to warrant further attention to selenium. 13 references, 4 figures, 2 tables.

Marine Geology and Geophysics Field Course Offered by The University of Texas Institute for Geophysics  

NASA Astrophysics Data System (ADS)

The University of Texas Institute for Geophysics, part of the Jackson School of Geosciences, annually offers an intensive three-week marine geology and geophysics field course during the spring-summer intersession. Now in year six, the course provides hands-on instruction and training for graduate and upper-level undergraduate students in data acquisition, processing, interpretation, and visualization. Techniques covered include high-resolution seismic reflection, CHIRP sub-bottom profiling, multibeam bathymetry, sidescan sonar, several types of sediment coring, grab sampling, and the sedimentology of resulting seabed samples (e.g., core description, grain size analysis, x-radiography, etc.). Students participate in an initial period of classroom instruction designed to communicate geological context of the field area (which changes each year) along with theoretical and technical background on each field method. The class then travels to the Gulf Coast for a week of at-sea field work. Our field sites at Port Aransas and Galveston, Texas, and Grand Isle, Louisiana, have provided ideal locations for students to investigate coastal and sedimentary processes of the Gulf Coast and continental shelf through application of geophysical techniques. In the field, students rotate between two research vessels: one vessel, the 22' aluminum-hulled R/V Lake Itasca, owned and operated by UTIG, is used principally for multibeam bathymetry, sidescan sonar, and sediment sampling; the other, NOAA's R/V Manta or the R/V Acadiana, operated by the Louisiana Universities Marine Consortium, and is used primarily for high-resolution seismic reflection, CHIRP sub-bottom profiling, multibeam bathymetry, gravity coring, and vibrocoring. While at sea, students assist with survey design, learn instrumentation set up, acquisition parameters, data quality control, and safe instrument deployment and retrieval. In teams of three, students work in onshore field labs preparing sediment samples for particle size analysis and initial post-processing of geophysical data. During the course's final week, teams return to the classroom where they integrate, interpret, and visualize data in a final project using industry-standard software such as Focus, Landmark, Caris, and Fledermaus. The course concludes with a series of professional-level final presentations and discussions with academic and industry supporters in which students examine the geologic history and sedimentary processes of the studied area of the Gulf Coast continental shelf. After completion, students report a greater understanding of marine geology and geophysics through the course's intensive, hands-on, team approach and low instructor to student ratio (12 students, three faculty, and three teaching assistants). This course satisfies field experience requirements for some degree programs and thus provides a unique alternative to land-based field courses.

Rising Above the Storm: DIG TEXAS  

NASA Astrophysics Data System (ADS)

For a decade Texas educators, scientists and citizens have shown a commitment to earth science education through planning at the national and state levels, involvement in earth science curriculum and teacher professional development projects, and the creation of a model senior level capstone Earth and Space Science course first offered in 2010 - 2011. The Texas state standards for Earth and Space Science demonstrate a shift to rigorous content, career relevant skills and use of 21st century technology. Earth and Space Science standards also align with the Earth Science, Climate and Ocean Literacy framework documents. In spite of a decade of progress K-12 earth science education in Texas is in crisis. Many school districts do not offer Earth and Space Science, or are using the course as a contingency for students who fail core science subjects. The State Board for Educator Certification eliminated Texas' secondary earth science teacher certification in 2009, following the adoption of the new Earth and Space Science standards. This makes teachers with a composite teacher certification (biology, physics and chemistry) eligible to teach Earth and Space Science, as well other earth science courses (e.g., Aquatic Science, Environmental Systems/Science) even if they lack earth science content knowledge. Teaching materials recently adopted by the State Board of Education do not include Earth and Space Science resources. In July 2011 following significant budget cuts at the 20 Education Service Centers across Texas, the Texas Education Agency eliminated key staff positions in its curriculum division, including science. This "perfect storm" has created a unique opportunity for a university-based approach to confront the crisis in earth science education in Texas which the Diversity and Innovation in the Geosciences (DIG) TEXAS alliance aims to fulfill. Led by the Texas A&M University College of Geosciences and The University of Texas Jackson School of Geosciences, with initial assistance of the American Geophysical Union, the alliance comprises earth scientists and educators at higher education institutions across the state, and science teachers, united to improve earth science literacy (geoscience-earth, ocean, atmospheric, planetary, and geography) among Texas science teachers in order to attract individuals from groups underrepresented in STEM fields to pursue earth science as a career. Members of the alliance are affiliated with one of eight regional DIG TEXAS hub institutions. With an NSF planning grant, DIG TEXAS leaders created the DIG TEXAS brand, developed a project website, organized and held the first community meeting in March, 2011 at Exxon Mobil's Training Center in Houston. DIG TEXAS members have also delivered testimony to the State Board for Educator Certification in support of a new earth science teacher certification and collaborated on proposals that seek funding to support recommendations formulated at the community meeting.

The geology and ground water resources of Calcasieu Parish, Louisiana  

USGS Publications Warehouse

Large quantities of fresh ground water are available in Calcasieu Parish. Fresh water is present in sand of Recent, Pleistocene, Pliocene, and Miocene ages, although locally only small supplies for rural or stock use can be obtained from the shallow sand lenses of Recent and Pleistocene ages. The principal fresh-water-bearing sands are the '200-foot,' '500-foot,' and '700-foot' sands of the Chicot aquifer of Pleistocene age, from which 105 million gallons is pumped daily. A yield of as much as 4,500 gpm (gallons per minute) has been obtained from a single well. The sands are typical of the Chicot aquifer throughout southwestern Louisiana in that generally they grade from fine sand at the top to coarse sand and gravel at the base of the aquifer. The coefficient of permeability of the principal sands in Calcasieu Parish ranges from 660 to about 2,000 gpd (gallons per day) per square foot and averages 1,200 gpd per square foot. The permeability of the sands generally varies with textural changes. The maximum depth of occurrence of fresh ground water in Calcasieu Parish ranges from about 700 feet to 2,500 feet below mean sea level; locally, however, where the sands overlie structures associated with oil fields, the maximum depth is less than 300 feet. Pumping has caused water levels to decline, at varying rates, in all the sands. In the '200-foot' sand they are declining at a rate of about 2 feet per year. In the industrial district of Calcasieu Parish, levels in the '500-foot' sand are declining at a rate of about 5 feet per year, and in the '700-foot' sand at a rate of about 3.5 feet per year. Salt-water contamination is accompanying the water-level decline in the '700-foot' sand in the central part of the parish. Quality-of-water data indicate that water from wells screened in the Chicot aquifer generally is suitable for some uses without treatment but would require treatment to be satisfactory for other uses. The temperature of the water ranges from 70? to 79?F. The lenticular sands of Pliocene and Miocene ages have not been used as a source of fresh ground water in Calcasieu Parish; however, north of the Houston River these formations contain fresh water, and the water contained in these formations in other parts of southwestern Louisiana is known to be soft and suitable for most purposes.

LSU Virtual Museum: Technology-Enhanced Geoscience Teacher Workshops for Louisiana K-8 Educators.  

NASA Astrophysics Data System (ADS)

The Virtual Museum, a Louisiana Board of Regents sponsored SELECT program, is a collaborative project between the Museum of Natural Science and the French Education Project at Louisiana State University. It offers Louisiana science teachers, in-training teachers, and immersion teachers a professional development program via six videoconferences. These videoconferences are broadcast from LSU to six distance-learning sites across the entire state of Louisiana. This unique teacher population was selected because in Louisiana, there are two types of K-8 science teachers: teachers in traditional classroom settings and teachers in immersion programs. In the Foreign language Immersion programs, the target language (French or Spanish) is the language of instruction and communication in the classroom. For each videoconference, teachers are provided content material that is prepared by geology faculty and graduate students, example of ongoing field research by LSU faculty members, classroom-ready activities, information on available loan material and on-line resources, training on the unique Scope-On-A-Rope microscope, pre-made PowerPoint presentations and virtual museum photos, all, in French and in English. Three of the videoconferences emphasize regional and statewide earth science topics including Louisiana fossils, rocks and minerals, and field techniques used to interpret Louisiana's geologic history. The activities provided for teachers are hands-on, inquiry based classroom exercises that focus on the availability of local materials. These activities can also be scaled for use in a variety of grade-levels and teachers are encouraged to use these activities in their classrooms. The program has proven to foster new collaboration between science teachers in regular programs and immersion schools while boosting the interest statewide for natural science topics.

Endemic tickborne infectious diseases in Louisiana and the Gulf South.  

PubMed

Most emerging infectious diseases today, such as West Nile virus and sudden acute respiratory distress syndrome (SARS), arise from zoonotic reservoirs and many are transmitted by arthropod vectors. Ticks are among the most competent and versatile arthropod vectors of infectious diseases because ticks of all ages and both sexes remain infectious for generations without having to reacquire infections from reservoir hosts. Today, ticks transmit the most common arthropod-borne infectious disease in the United States (US), Lyme disease (LD); and the most lethal arthropod-borne infectious disease in the US, Rocky Mountain spotted fever (RMSF). Both LD and RMSF are endemic in Louisiana and the Gulf South. Ticks have also become frequent vectors of emerging zoonotic diseases in the Gulf South, including southern tick-associated rash illness (STARI), transmitted by the lone star tick, and Maculatum disease, transmitted by the Gulf Coast tick. Recent environmental changes and human lifestyle choices now place humans and ticks together outdoors in the Gulf South for longer periods in welcoming ecosystems for breeding, blood-feeding, and infectious disease transmission. An increasing incidence of emerging and re-emerging, endemic infectious diseases transmitted by existing and unanticipated tick vectors may be expected. PMID:20108827

Daily movements of female mallards wintering in Southwestern Louisiana  

USGS Publications Warehouse

Understanding daily movements of waterfowl is crucial to management of winter habitats, especially along the Gulf Coast where hunting pressure is high. Radio-telemetry was used to investigate movements of female Mallards (Anas platyrchychos) wintering in southwestern Louisiana. Movement distances were analyzed from 2,455 paired locations (diurnal and nocturnal) of 126 Mallards during winters 2004-2005 and 2005-2006 to assess effects of winter, female age, areas closed (Lacassine National Wildlife Refuge [LAC], Cameron Prairie National Wildlife Refuge [CAM], Amoco Pool [AMOCO] or open to hunting [OPEN]), and habitat type, including all interactions. Movement distances from the various land management categories were not consistent by age, date, or by winter. Flight distances from LAC increased with date, whereas those from CAM and OPEN did not vary significantly by date. Female Mallards moved short distances between diurnal and nocturnal sites (ranging from 3.1 to 15.0 km by land management category), suggesting that they are able to meet their daily energy requirements within a smaller area than Northern Pintails (Anas acuta, hereafter Pintails), and thus minimize transit energy costs.

Seasonal sleep effects on Louisiana aerial applicators' safety.  

PubMed

Sleep management is one of the documented factors affecting safety and health. Using SLEEP (Sleep Loss Effects on Everyday Performance), a web-based model that integrates the dynamics of sleep to predict performance loss, aerial applicators licensed to work in the state of Louisiana were surveyed and evaluated for sleep deprivation. On and off season sleeping patterns were compared. During the off season, agricultural pilots reported having average sleeping time (6.9 hours), while during the farming season, because of their grueling schedule (sometimes working 100 hours a week), pilots reported sleeping only 3 hours per day in the week before the survey was made. Sleep deprivation greatly increases the chances of accidents. In the Mississippi delta region, 84% of the fatal accidents in the past nine years involving agricultural pilots were ruled as caused by human factors. Younger pilots are particularly at risk due to their limited flying experience and greater sleep needs. The agricultural pilot community would likely benefit from educational programs focused on better sleep management and the value and limitations of countermeasures to cope with fatigue.

Detrimental impacts of radiotransmitters on juvenile Louisiana Waterthrushes  

USGS Publications Warehouse

The Louisiana Waterthrush (waterthrush: Seiurus motacilla) is a forest-dwelling, Nearctic-Neotropical migratory passerine that nests along streams. We attached radiotransmitters (0.6-0.8 g) to 12 nestling waterthrushes using snug, elastic loops. At three nests, adult waterthrushes were videotaped removing radio-tagged young from the nest. In addition, we recovered nine radio-backpacks (with two still attached to the carcasses of nestlings) near nests within a few days after attaching transmitters. Only one of 12 radio-tagged young was relocated more than 24 h after attaching the transmitter. Thus, the method of transmitter attachment we used was not effective. Using snug, nonelastic loops (e.g., nylon) for the harness may reduce the loss of transmitters, but may injure the skin as fledglings grow. Other possible alternatives include (1) gluing the transmitter to skin on the back of nestlings, (2) capturing fledglings in mist nets and attaching transmitters a week or more after fledging by which time contour feathers have grown and the likelihood of a parent removing the transmitter may be reduced, or (3) attempting to monitor fledglings without attaching transmitters. The success of the latter two alternatives would likely be enhanced by attaching transmitters to adults and then tracking them to locate their still-dependent fledglings.

Risk assessment for produced water discharges to Louisiana Open Bays  

SciTech Connect

Data were collected prior to termination of discharge at three sites (including two open bay sites at Delacroix Island and Bay De Chene) for the risk assessments. The Delacroix Island Oil and Gas Field has been in production since the first well drilling in 1940; the Bay De Chene Field, since 1942. Concentrations of 226Ra, 228Ra, 210Po, and 228Th were measured in discharges. Radium conc. were measured in fish and shellfish tissues. Sediment PAH and metal conc. were also available. Benthos sampling was conducted. A survey of fishermen was conducted. The tiered risk assessment showed that human health risks from radium in produced water appear to be small; ecological risk from radium and other radionuclides in produced water also appear small. Many of the chemical contaminants discharged to open Louisiana bays appear to present little human health or ecological risk. A conservative screening analysis suggested potential risks to human health from Hg and Pb and a potential risk to ecological receptors from total effluent, Sb, Cd, Cu, Pb, Ni, Ag, Zn, and phenol in the water column and PAHs in sediment; quantitiative risk assessments are being done for these contaminants.

Cost effectiveness of the stream-gaging program in Louisiana  

USGS Publications Warehouse

This report documents the results of a study of the cost effectiveness of the stream-gaging program in Louisiana. Data uses and funding sources were identified for the 68 continuous-record stream gages currently (1984) in operation with a budget of $408,700. Three stream gages have uses specific to a short-term study with no need for continued data collection beyond the study. The remaining 65 stations should be maintained in the program for the foreseeable future. In addition to the current operation of continuous-record stations, a number of wells, flood-profile gages, crest-stage gages, and stage stations, are serviced on the continuous-record station routes; thus, increasing the current budget to $423,000. The average standard error of estimate for data collected at the stations is 34.6%. Standard errors computed in this study are one measure of streamflow errors, and can be used as guidelines in comparing the effectiveness of alternative networks. By using the routes and number of measurements prescribed by the ' Traveling Hydrographer Program, ' the standard error could be reduced to 31.5% with the current budget of $423,000. If the gaging resources are redistributed, the 34.6% overall level of accuracy at the 68 continuous-record sites and the servicing of the additional wells or gages could be maintained with a budget of approximately $410,000.

Suicide mortality rates in Louisiana, 1999-2010.  

PubMed

This report is a descriptive study on suicide deaths in Louisiana occurring in the years 1999 to 2010. Mortality data was collected from death certificates from this 12-year period to describe suicide mortality by year, race, sex, age group, and methods of suicide. Data were also compared to national data. Rates and methods used to commit suicide vary greatly according to sex, race, and age. The highest rates were observed in white males, followed by black males, white females, and black females. Older white males had the highest suicide rates. The influence of age was modulated by the sex and race categories. Firearm was the most common method used in all four categories. Other less common methods were hanging/strangulation/suffocation (HSS) and drugs/alcohol. Although no parish-level data were systematically analyzed, a comparison of suicide rates post-Katrina versus pre-Katrina was done for Orleans Parish, the rest of the Greater New Orleans area, and a comparison group. It appears that rates observed among whites, particularly males, were higher after Katrina. Data based on mortality do not give a comprehensive picture of the burden of suicide, and their interpretation should be done with caution. PMID:23362593

Time of travel of solutes in the Vermilion River, Louisiana  

USGS Publications Warehouse

Dye-tracer studies were made in November 1978 and in June 1979 to define streamflow patterns in the Vermilion River. For the November 1978 study the tracer was injected at two locations, Surrey Street in Lafayette and about 7 miles downstream at State Highway 3073; the discharge at Surrey Street at the time of injection was 218 cubic feet per second. The two dye clouds merged at Broussard Cemetery, about 12.2 miles downstream from Surrey Street, after an elapsed time of about 270 hours. After 438 hours the dye cloud extended form the Abbeville bridge (Louisiana Highway 14 Bypass) upstream about 14.5 miles. In June 1979, a tracer was injected into the river at Surrey Street at Lafayette; the discharge at Surrey Street at the time of injection was 161 cubic feet per second. Forty-two hours after injection the leading edge of the tracer was located at the Milton pumping plant, 14 miles downstream from the injection site. The average pumping rate of the plant during the study was 440 cubic feet per second. Ninety hours after injection, no indication of the tracer was found in the river, but the tracer was found in a rice-irrigation cannal at State Highway 14, about 10 miles west of Abbeville. (USGS)

The Louisiana Medicare Electro-Convulsive Therapy Quality Improvement Project.  

PubMed

The first collaborative statewide psychiatric quality improvement project, initiated by Louisiana Health Care Review, Inc, focused on the practice of inpatient electro-convulsive therapy (ECT) among Medicare patients. Data from the project indicated that the majority of Medicare patients receiving ECT were white females living at home, in good physical health, in their seventies, and with a diagnosis of major depression or major depression with psychotic features. The quality indicators for the project included: (documentation of) monitoring of cognitive side effects, monitoring of depressive target symptoms, ECT appropriateness, electrode placement, anesthesia evaluation, and dental examination. An additional indicator (administration of possibly detrimental medication during ECT) was developed based on the recommendation by the study group. At project conclusion, significant improvement occurred in all project indicators. ECT as practiced in the participating hospitals was effective and appropriate. Appropriateness was determined as depression refractory to two medication trails or an emergency due to severe suicidal ideation or physical deterioration secondary to malnutrition. Transient hypertension (13%) and cardiac dysrhythmia (3.5%) which resolved in the recovery period were the most frequent complications. PMID:10546434

Nutrient fluxes in a eutrophic coastal Louisiana freshwater lake  

NASA Astrophysics Data System (ADS)

Nitrogen and phosphorus cycling in a eutrophic Louisiana freshwater lake system (Lac des Allemands) was studied. Nutrients from runoff entering the lake, as well as sediment-interstitial and lake water nitrogen and phosphorus fractions, were measured seasonally. Sedimentation rates in the lake were determined using137Cs dating. Phosphorus levels in the lake were found to be largely dependent on concentrations in the incoming bayou water from upland drainage. Lake water concentrations appear to respond to fluctuations in incoming waters. Laboratory equilibrium studies showed bottom sediments in the lake are a major sink for the incoming dissolved orthophosphate phosphorus. Total nitrogen concentrations in the lake water generally exceeded incoming runoff concentrations, suggesting fixation by the large blue-green algae population in the lake as being the major source of nitrogen to the system. Sedimentation ranged from 0.44 cm/year to 0.81 cm/year, depending on the proximity to the inlet bayous. Even though the lake is eutrophic the sediment served as a buffer by removing large amounts of carbon, nitrogen, and phosphorus through sedimentation processes. Carbon, nitrogen, and phosphorus were accumulating in the sediment at rates of 60, 7.1, and 1.1 g/m2/year, respectively. The water quality of the lake is likely to continue to decline unless measures are taken to reduce municipal, industrial, and agricultural inputs of phosphorus into the lake.

Pollen-mediated introgression and hybrid speciation in Louisiana irises.  

PubMed Central

Populations of the "Louisiana iris" species Iris fulva, I. hexagona, and I. nelsonii were examined genetically to test for interspecific gene flow between I. fulva and I. hexagona, for pollen- versus seed-mediated introgression between these species, and for the presumed hybrid origin of I. nelsonii. Genetic markers were identified by using both a polymerase chain reaction-like method that allows the identification of random, nuclear markers and standard polymerase chain reaction experiments involving specific chloroplast DNA (cpDNA) oligonucleotides. Restriction endonuclease digestions of the cpDNA amplification products resolved diagnostic restriction site differences for I. fulva and I. hexagona. The distribution of the species-specific nuclear markers supports a hypothesis of bidirectional introgression between I. fulva and I. hexagona. Thus, individuals analyzed from a contemporary hybrid population demonstrate multilocus genotypes that are indicative of advanced-generation hybrid individuals. Furthermore, several markers from the alternate species were present in low frequency in one allopatric population each of I. fulva and I. hexagona. Data from the nuclear analysis also support the hypothesized hybrid origin of I. nelsonii from the interaction of I. fulva and I. hexagona. Finally, cpDNA data support the hypothesis that the localized and the dispersed introgression are largely due to pollen transfer. In addition to the biological implications, this study demonstrates the power of the polymerase chain reaction methodology for the rapid identification of random and specific genetic markers for testing evolutionary genetic hypotheses.

Old World hantaviruses in rodents in New Orleans, Louisiana.  

PubMed

Seoul virus, an Old World hantavirus, is maintained in brown rats and causes a mild form of hemorrhagic fever with renal syndrome (HFRS) in humans. We captured rodents in New Orleans, Louisiana and tested them for the presence of Old World hantaviruses by reverse transcription polymerase chain reaction (RT-PCR) with sequencing, cell culture, and electron microscopy; 6 (3.4%) of 178 rodents captured--all brown rats--were positive for a Seoul virus variant previously coined Tchoupitoulas virus, which was noted in rodents in New Orleans in the 1980s. The finding of Tchoupitoulas virus in New Orleans over 25 years since its first discovery suggests stable endemicity in the city. Although the degree to which this virus causes human infection and disease remains unknown, repeated demonstration of Seoul virus in rodent populations, recent cases of laboratory-confirmed HFRS in some US cities, and a possible link with hypertensive renal disease warrant additional investigation in both rodents and humans.

Water-level surface in the Chicot equivalent aquifer system in southeastern Louisiana, 2009  

USGS Publications Warehouse

The Chicot equivalent aquifer system is an important source of freshwater in southeastern Louisiana. In 2005, about 47 million gallons per day (Mgal/d) were withdrawn from the Chicot equivalent aquifer system in East Baton Rouge, East Feliciana, Livingston, Tangipahoa, St. Helena, St. Tammany, Washington, and West Feliciana Parishes. Concentrated withdrawals exceeded 5 Mgal/d in Bogalusa, the city of Baton Rouge, and in northwestern East Baton Rouge Parish. In the study area, about 30,000 wells screened in the Chicot equivalent aquifer system were registered with the Louisiana Department of Transportation and Development (LaDOTD). These wells were constructed for public-supply, industry, irrigation, and domestic uses. Most of the wells were registered as domestic-use wells and are small-diameter, low-yielding wells. Total withdrawal from the Chicot equivalent aquifer system for domestic use was estimated to be 12 Mgal/d in 2005. This report documents the 2009 water-level surface of the Chicot equivalent aquifer system in southeastern Louisiana. The report also shows differences in water-level measurements for the years 1991 and 2009 at selected sites. Understanding changes and trends in water levels is important for continued use, planning, and management of groundwater resources. The U.S. Geological Survey, in cooperation with the Louisiana Department of Transportation and Development, conducted this study of the water-level surface of the Chicot equivalent aquifer system as part of an ongoing effort to monitor groundwater levels in aquifers in Louisiana.

Students Across Texas Celebrate Astronomy Day  

NASA Astrophysics Data System (ADS)

Over the past three years, McDonald Observatory has offered special Astronomy Day videoconference programs to students across Texas—the second largest state in the U.S. (Only Alaska is larger). Videoconferencing allows many students and teachers access to our Observatory, which is remotely located 180 miles (290 kilometers) from any major city. McDonald Observatory partners with Connect2Texas to advertise the Astronomy Day event. Connect2Texas provides the electronic bridge between schools and the Observatory. They also provide an online evaluation for teachers to complete. In 2009 the Astronomy Day videoconference celebrated the International Year of Astronomy and the historic observations made by Galileo Galilei. During the videoconference, the classes explore the Moon or Venus by making real-time telescopic observations. Students also receive an introduction to the Observatory, an opportunity to perform an activity relating to Galileo's observations, and an interview with an astronomer. A website provides teachers pre-and post-video conference materials, instructions, and a certificate of completion that can be customized for each student. The website also lists content alignment with state science education standards.

Texas Intense Positron Source (TIPS)  

NASA Astrophysics Data System (ADS)

The Texas Intense Positron Source (TIPS) is a state of the art variable energy positron beam under construction at the Nuclear Engineering Teaching Laboratory (NETL). Projected intensities on the order of the order of 10^7 e+/second using ^64Cu as the positron source are expected. Owing to is short half-life (t1/2 12.8 hrs), plans are to produce the ^64Cu isotope on-site using beam port 1 of NETL TRIGA Mark II reactor. Following tungsten moderation, the positrons will be electrostatically focused and accelerated from few 10's of eV up to 30 keV. This intensity and energy range should allow routine performance of several analytical techniques of interest to surface scientists (PALS, PADB and perhaps PAES and LEPD.) The TIPS project is being developed in parallel phases. Phase I of the project entails construction of the vacuum system, source chamber, main beam line, electrostatic/magnetic focusing and transport system as well as moderator design. Initial construction, testing and characterization of moderator and beam transport elements are underway and will use a commercially available 10 mCi ^22Na radioisotope as a source of positrons. Phase II of the project is concerned primarily with the Cu source geometry and thermal properties as well as production and physical handling of the radioisotope. Additional instrument optimizing based upon experience gained during Phase I will be incorporated in the final design. Current progress of both phases will be presented along with motivations and future directions.

Lessons learned from hazardous chemical incidents--Louisiana Hazardous Substances Emergency Events Surveillance (HSEES) system.  

PubMed

Since 2001, the Louisiana Department of Health and Hospitals (LDHH) has participated in the Hazardous Substances Emergency Events Surveillance (HSEES) system. In 2001, there were 815 events qualified for HSEES surveillance. Data for each event was gathered and analyzed. During these hazardous substances events, there were 1164 chemicals released resulting in injuries to 63 people, most with respiratory system irritation. Even though more people were injured in fixed-facility events, injuries were more likely to result from transportation-related events. The quantity and frequency of hazardous substance releases do not always positively correlate with the number of injuries sustained during those releases. A higher percentage of "Rail" transport events was observed in Louisiana when compared with other HSEES states. By collecting and analyzing more data and disseminating results to the public, it is expected that further adverse public health consequences from hazardous releases/spills in Louisiana can be reduced and/or minimized.

The paper gives an assay of West Texas Intermediate, one of the world's market crudes. The price of this crude, known as WTI, is followed by market analysts, investors, traders, and industry managers around the world. WTI price is used as a benchmark for pricing all other US crude oils. The 41[degree] API < 0.34 wt % sulfur crude is gathered in West Texas and moved to Cushing, Okla., for distribution. The WTI posted prices is the price paid for the crude at the wellhead in West Texas and is the true benchmark on which other US crudes are priced. The spot price is the negotiated price for short-term trades of the crude. And the New York Mercantile Exchange, or Nymex, price is a futures price for barrels delivered at Cushing.

Rain-related Fatal Crashes in Texas  

NASA Astrophysics Data System (ADS)

Weather has a direct impact on traffic safety. This study focuses on fatal crashes in the presence of rain. We reviewed information related to the events that lead to rain- related crashes in the Texas since 1982. Analysis of the data reveals that 12.4% of crashes in Texas were rain-related. Most rain-related crashes are located in Texas "Flash Flood Alley" which includes major urban centers. Fatal crash data and GIS are used to explore and identify the spatio-temporal distribution of the crashes. Spatial statistical techniques are used to identify significant patterns of rain-related fatal crashes. Logistic and nonlinear regression is used to identify and rank all environmental and non-environmental factors that contribute to fatal crashes. Focus will be on factors that amplify the rain effect. Identifying the variables contributing to these fatal crash types is necessary for the implementation of effective countermeasures for road weather safety purposes.

Sequence stratigraphy interpretation of the central shelf area, offshore Louisiana  

SciTech Connect

Sequence stratigraphy methods are demonstrated on a Halliburton regional seismic line and several well logs near the Eugene Island-Ship Shoal border off the central Louisiana shelf area of the Gulf of Mexico. The example shows five sequences of Pliocene-Pleistocene age interpreted by synthesizing log character, biostratigraphy and seismic character. These sequences show the complete range of shallow water to deeper water systems tracts, demonstrating a significant presence of lowstand wedge sediments high onto the present-day shelf. The study area shows exceptional development of the transgressive systems tract between the 2.4 and 3.0-m.y. sequence boundaries. This is evidenced by apparent truncation on seismic and corresponds to an overall shaly unit which contains several parasequences identified in well logs. The individual sands of the parasequences are easily correlated from well to well. The Lenticulina 1 paleo picks fluctuate between the 1.6 and 2.4-m.y. sequences but generally occur near the top of the 2.4- m.y. transgression. The 2.4-m.y. sequence boundary is deeply incised and filled with lowstand wedge prograding sands and shales. The 3.0, 3.8, and 4.2-m.y. sequences show an increasing thickness of lowstand wedge sediments and mounded slope fan seismic character with some channelized gull wing development. Several sands with blocky log character are interpreted as channelized portions of the slope fan. Updip along the sequence boundary, the proximal slope fan seismic facies character becomes dominant, i.e., much more laterally continuous seismic reflectors with few mounds.

The Louisiana State University waste-to-energy incinerator  

NASA Astrophysics Data System (ADS)

This proposed action is for cost-shared construction of an incinerator/steam-generation facility at Louisiana State University under the State Energy Conservation Program (SECP). The SECP, created by the Energy Policy and Conservation Act, calls upon DOE to encourage energy conservation, renewable energy, and energy efficiency by providing Federal technical and financial assistance in developing and implementing comprehensive state energy conservation plans and projects. Currently, LSU runs a campus-wide recycling program in order to reduce the quantity of solid waste requiring disposal. This program has removed recyclable paper from the waste stream; however, a considerable quantity of other non-recyclable combustible wastes are produced on campus. Until recently, these wastes were disposed of in the Devil's Swamp landfill (also known as the East Baton Rouge Parish landfill). When this facility reached its capacity, a new landfill was opened a short distance away, and this new site is now used for disposal of the University's non-recyclable wastes. While this new landfill has enough capacity to last for at least 20 years (from 1994), the University has identified the need for a more efficient and effective manner of waste disposal than landfilling. The University also has non-renderable biological and potentially infectious waste materials from the School of Veterinary Medicine and the Student Health Center, primarily the former, whose wastes include animal carcasses and bedding materials. Renderable animal wastes from the School of Veterinary Medicine are sent to a rendering plant. Non-renderable, non-infectious animal wastes currently are disposed of in an existing on-campus incinerator near the School of Veterinary Medicine building.

Temperature and petroleum generation history of the Wilcox Formation, Louisiana  

USGS Publications Warehouse

A one-dimensional petroleum system modeling study of Paleogene source rocks in Louisiana was undertaken in order to characterize their thermal history and to establish the timing and extent of petroleum generation. The focus of the modeling study was the Paleocene and Eocene Wilcox Formation, which contains the youngest source rock interval in the Gulf Coast Province. Stratigraphic input to the models included thicknesses and ages of deposition, lithologies, amounts and ages of erosion, and ages for periods of nondeposition. Oil-generation potential of the Wilcox Formation was modeled using an initial total organic carbon of 2 weight percent and an initial hydrogen index of 261 milligrams of hydrocarbon per grams of total organic carbon. Isothermal, hydrous-pyrolysis kinetics determined experimentally was used to simulate oil generation from coal, which is the primary source of oil in Eocene rocks. Model simulations indicate that generation of oil commenced in the Wilcox Formation during a fairly wide age range, from 37 million years ago to the present day. Differences in maturity with respect to oil generation occur across the Lower Cretaceous shelf edge. Source rocks that are thermally immature and have not generated oil (depths less than about 5,000 feet) lie updip and north of the shelf edge; source rocks that have generated all of their oil and are overmature (depths greater than about 13,000 feet) are present downdip and south of the shelf edge. High rates of sediment deposition coupled with increased accommodation space at the Cretaceous shelf margin led to deep burial of Cretaceous and Tertiary source rocks and, in turn, rapid generation of petroleum and, ultimately, cracking of oil to gas.

Spatial variability of phosphorus sorption dynamics in Louisiana salt marshes  

NASA Astrophysics Data System (ADS)

(P) biogeochemistry has been studied in multiple wetland ecosystems, though few data exist on P sorption in U.S. Gulf Coast marshes. There also is a limited understanding of how oil spills in coastal zones can influence P dynamics in wetland soils. In this study, we measured P sorption potential, using the P sorption index (PSI), soil properties, and P saturation at increasing distances from the marsh edge in oiled and unoiled marshes in three regions along the southeastern Louisiana coast (Terrebonne Bay, western, and eastern Barataria Bay). Individual PSI values were highly variable, ranging from 19.5 to 175.6 mg P 100 g-1 and varying by at least a factor of five within each of the three regions, and did not significantly differ between regions or between oiled and unoiled marshes. Soil pH, organic matter, total N, N:P ratio, moisture content, cation exchange capacity, and P saturation differed between regions, and all soil parameters showed great variability between and within individual marshes. Extractable iron was the strongest predictor of PSI across all regions, explaining between 51 and 95% of the variability in individual regions. PSI increased with distance from marsh edge in Terrebonne Bay where other soil properties exhibited similar trends. Results suggest mineral composition of marsh soils, influenced by elevation-inundation gradients, are critical in dictating P loading to estuaries and open waters, and overall marsh functioning. Further, within 2 years of the Deepwater Horizon oil spill, oiled marshes are able to sorb phosphorus at comparable levels as unoiled marshes.

The 3D Elevation Program: summary for Louisiana  

USGS Publications Warehouse

Elevation data are essential to a broad range of applications, including forest resources management, wildlife and habitat management, national security, recreation, and many others. For the State of Louisiana, elevation data are critical for flood risk management, natural resources conservation, agriculture and precision farming, infrastructure and construction management, water supply and quality, and other business uses. Today, high-density light detection and ranging (lidar) data are the primary sources for deriving elevation models and other datasets. Federal, State, Tribal, and local agencies work in partnership to (1) replace data that are older and of lower quality and (2) provide coverage where publicly accessible data do not exist. A joint goal of State and Federal partners is to acquire consistent, statewide coverage to support existing and emerging applications enabled by lidar data. The National Enhanced Elevation Assessment evaluated multiple elevation data acquisition options to determine the optimal data quality and data replacement cycle relative to cost to meet the identified requirements of the user community. The evaluation demonstrated that lidar acquisition at quality level 2 for the conterminous United States and quality level 5 ifsar data for Alaska with a 6- to 10-year acquisition cycle provided the highest benefit/cost ratios. The 3D Elevation Program (3DEP) initiative selected an 8-year acquisition cycle for the respective quality levels. 3DEP, managed by the U.S. Geological Survey (USGS), the Office of Management and Budget Circular A–16 lead agency for terrestrial elevation data, responds to the growing need for high-quality topographic data and a wide range of other 3D representations of the Nation’s natural and constructed features.

Fish Consumption and Mercury Exposure among Louisiana Recreational Anglers  

PubMed Central

Background Methylmercury (MeHg) exposure assessments among average fish consumers in the United States may underestimate exposures among U.S. subpopulations with high intakes of regionally specific fish. Objectives We examined relationships among fish consumption, estimated mercury (Hg) intake, and measured Hg exposure within one such potentially highly exposed group, recreational anglers in the state of Louisiana, USA. Methods We surveyed 534 anglers in 2006 using interviews at boat launches and fishing tournaments combined with an Internet-based survey method. Hair samples from 402 of these anglers were collected and analyzed for total Hg. Questionnaires provided information on species-specific fish consumption during the 3 months before the survey. Results Anglers’ median hair Hg concentration was 0.81 ?g/g (n = 398; range, 0.02–10.7 ?g/g); 40% of participants had levels >1 ?g/g, which approximately corresponds to the U.S. Environmental Protection Agency’s reference dose. Fish consumption and Hg intake were significantly positively associated with hair Hg. Participants reported consuming nearly 80 different fish types, many of which are specific to the region. Unlike the general U.S. population, which acquires most of its Hg from commercial seafood sources, approximately 64% of participants’ fish meals and 74% of their estimated Hg intake came from recreationally caught seafood. Conclusions Study participants had relatively elevated hair Hg concentrations and reported consumption of a wide variety of fish, particularly locally caught fish. This group represents a highly exposed subpopulation with an exposure profile that differs from fish consumers in other regions of the United States, suggesting a need for more regionally specific exposure estimates and public health advisories.

Long-term growth trends of baldcypress (Taxodium distichum (L.) rich.) at Caddo Lake, Texas  

USGS Publications Warehouse

Caddo Lake, situated on the border of northeast Texas and northwest Louisiana, USA is a medium-sized lake dominated by stands of baldcypress (Taxodiwn distichum). A study of tree growth was initiated at Caddo Lake to address concerns about the health of the baldcypress ecosystem. The lake has been subjected to several dramatic water-level changes over the past 200 years, including water-level stabilization following dam construction in 1914. To assess the long-term growth trends of baldcypress trees and determine if a recent growth decline is occurring at Caddo Lake, increment cores were taken from 52 trees. The cores were crossdated and rings between the years 1900 and 1992 measured to the nearest 0.01 mm. Most cores were characterized by high variation in year-to-year growth. Although increasing growth rates were observed at most locations, trees from two backwater areas of the lake had recent growth rates lower than their long-term average. Growth amounts at these two sites were, however, within the historic range of variation. No recruitment was observed. From these data, we can conclude that the historic, extreme changes in hydrologic regime and the current stabilized water levels have not resulted in an overall decline in baldcypress growth at Caddo Lake.
