Item 1291/1271 of dissolved organic iodine: A novel tool for tracing terrestrial organic matter in estuarine surface waters of Galveston Bay, Texas(2004 Feb 15) Schwehr KA; Santschi PH; Elmore D;Conference papers indexItem The 1952 waterfowl hunting season.(1953) Singleton, J.R.;The 1952 waterfowl hunting season opened on October 31, following a period of extreme drought on the Texas Gulf Coast. Surface water was limited to flooded rice fields and irrigation systems, and to the coastal marshes, the latter being saline. Reports from the nesting grounds were highly favorable, and the prospects for a successful hunting season were not discouraging. These prospects would have been improved by rainfall in late October, which was not to be had. Waterfowl range conditions were very poor under these circumstances. Native foods were not abundant and marsh burning in August and September was of doubtful benefit to waterfowl in the absence of sufficient rainfall. Thus, in the northeastern portion of the coast, food was limited primarily to waste of lost grain in the harvested rice fields. Drought conditions did not restrict the growth of submerged saline aquatics of the shallow bays on the southern coast and native foods were sufficient. Thus, the season opened with a reduced carrying capacity on approximately one-half of the coast and normal carrying capacity on the remaining one-half.Item 1987 Census of agriculture, volume 1, geographic area series, part 43 Texas state and county data(U.S. Dept. of Commerce, Bureau of the Census, 1989) U.S. Bureau of the Census;NOT AVAILABLE IN HOUSE EASItem The 1993 Regional Environmental Monitoring and Assessment Program (R-EMAP) study of Galveston Bay, Texas(1999 1998 Mar 26) Gorham-Test C;The Regional Environmental Monitoring and Assessment Program (R-EMAP) Study of Galveston Bay, Texas addresses the ecological health of this estuary by identifying benthic community structure, measuring toxicity of sediments, and measuring concentrations of various pollutants in the sediments. The Sediment Quality Triad approach was used in this study to differentiate between degraded sites and undegraded sites. For comparison of the main body of Galveston Bay with other systems and the Louisianian Province as a whole, twenty-nine randomly selected sites were chosen to represent 1305 km super(2) of the Galveston Bay System. Random sites are located in Galveston Bay, Trinity Bay, East Bay and West Bay. In addition, a sample was taken for each of four important small bays associated with Galveston Bay, and for five marinas. This study does not include an analysis of the upper Houston Ship Channel, the Trinity River, or any other major tributaries. The Benthic Index, the Benthic Diversity Index, and abundance of Amphipods at each site proved useful in demonstrating that communities living in contaminated sediments had a community structure indicating poor conditions. The proportions of the two indices in the Galveston Bay area were similar to the proportions reported for the Louisianian Province in the 1993 EMAP StudyItem Item 21Years of Shoreline Change on Mustang Island Gulf beach. www.glo.state.tx.us(1994) Coastal Coordination Council; ;No abstract availableItem Item Abstracts of the annual meeting of the Gulf Coast Chapter of Society of Toxicology, November(Taylor & Francis Ltd, 1997 Jul)Presents an abstract of the article `Sensitivity of Various Biomarkers for Polynuclear Aromatic Hydrocarbon Contamination in Two Fish Species from Galveston Bay,' by K. Willett, S. McDonald, M. Steinberg, K. Beatty and S. Safe which was discussed at the 1996 annual meeting of the Gulf Coast Chapter of the Society of ToxicologyItem Abundance and distribution of the Western Gulf Stone Crab (Menippe adina) in Galveston Bay, Texas.(Texas A&M University., 1989) Boslet, J.M.;Abundance and distribution of the western Gulf stone crab (Menippe adina) in Galveston Bay were determined by sampling weekly from June through November 1987. Catch per unit effort (CPUE; # of crabs/trap/ 48-hr) was calculated for both sexes combined, each sex, and gravid females by month, habitat, and depth. CPUE valves exceeded 1.00 every month with peak catch rates above 2.00 from July -September in channel habitats. Highest overall CPUE values (1.94) occurred in waters greater than 2.4 m deep. Oyster reef and non-reef/channel habitats yielded low to moderate overall CPUE values of 0.12 and 0.68, respectively.Item Abundance and vertical flux of Pseudo-nitzschia in the northern Gulf of Mexico(1997 Jan) Dortch Q; Robichaux R; Pool S; Milsted D; Mire G; Rabalais NN; Soniat TM; Fryxell GA; Turner RE; Parsons ML; Marine Ecology-Progress SeriesMany species of the ubiquitous pennate diatom genus Pseudo-nitzschia have recently been discovered to produce domoic acid, a potent neurotoxin which causes Amnesic Shellfish Poisoning (ASP). Pseudo-nitzschia spp. were extremely abundant (up to 10(8) cells l(-1); present in 67% of 2195 samples) from 1990 to 1994 on the Louisiana and Texas, USA, continental shelves and moderately abundant (up to 10(5) cells l(-1); present in 18% of 192 samples) over oyster beds in the Terrebonne Bay estuary in Louisiana in 1993 and 1994. On the shelf there was a strong seasonal cycle with maxima every spring for 5 yr and sometimes in the fall, which were probably related to river flow, water column stability, and nutrient availability. In contrast, in the estuary there was no apparent seasonal cycle in abundance, but the time series of data is relatively short and the environment highly variable. At one site on the shelf, where sediment traps were deployed from spring to fall and sampled at frequent intervals in both 1990 and 1991, approximately 50% of the Pseudo-nitzschia spp. cells present in the water sank into sediment traps. Pseudo-nitzschia spp. were also abundant in surficial sediments. The species of Pseudo-nitzschia present, during this study were not routinely identified with the methods employed. However, toxin-producing P. multiseries has been identified previously from Galveston Bay, Texas, and cells from a bloom on the shelf in June 1993 were identified by scanning electron microscopy as P. pseudodelicatissima, which is sometimes toxic. Although there have been no known outbreaks of ASP in this area, historical data suggests that Pseudo-nitzschia spp,abundance may have increased on the shelf since the 1950s. It is hypothesized that the increase is due to doubling of the nutrient loading from the Mississippi and Atchafalaya rivers and increased eutrophication on the shelfItem Abundance of postlarval and juvenile shrimp.(1964) Baxter, K.N.; Knight, C.E.; Furr, C.H.;Data on the relative abundance of postlarval and juvenile brown shrimp in Galveston Entrance and Sabine Pass (Texas) pointed toward a low harvest of brown shrimp along the upper Texas coast during the latter half of the 1964 season.Item Accumulation and depuration of organic contaminants by the American oyster (Crassostrea virginica)(1996 Jan 26) Sericano JL; Wade TL; Brooks JM; Science of the Total EnvironmentOysters and other bivalves are widely used to assess the levels of environmental contamination; however, very little actual field calibration of bivalves has been done. The purpose of this research, therefore, has been to evaluate the uptake and depuration of selected PCBs and PAHs in transplanted American oysters, Crassostrea virginica, under field conditions in Galveston Bay, Texas. Transplanted oyster were found to bioaccumulate contaminants and reach concentrations nearly equal to those of indigenous oysters for PAHs and low molecular weight PCBs within 30-48 days. In contrast, high molecular weight PCBs did not reach equivalent concentrations. When returned to a clean environment, oysters significantly depurated PAHs and low molecular weight PCBs. There were, however, differences in depuration rates when newly contaminated oysters were compared to chronically contaminated oysters. Oysters are useful tools in biomonitoring studies but have their limitations. Transplant studies help to establish these limitations on the use of oysters as sentinel organisms to avoid misleading interpretation of the oyster contaminant concentrationsItem Accuracy assessment and validation of classified satellite imagery of Texas coastal wetlands(1994) Hinson JM; German CD; Pulich W Jr Engelhardt R;Two methods of determining wetlands and landcover classification accuracy for Landsat thematic mapper (TM) imagery are presented and evaluated. A partial Landsat TM scene of the upper Texas coast (Galveston Bay) was classified according to the NOAA CoastWatch-Change Analysis Program landcover classification scheme. Thirteen major wetland, upland and open water landcover types were identified using a series of supervised and unsupervised classification procedures. The classification accuracy was estimated using two accuracy assessment methods: ground truthing 407 sites located with Global Positioning System (GPS) and direct overlay of wetland categories with comparable United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) data. Comparisons of the accuracy assessment estimates found that the ground truthing method consistently produced higher accuracy estimates than that of the direct overlay method. It was concluded that ancillary data as a means of accuracy assessment for classified imagery as an alternative to ground truthing should be used with cautionItem Active faults, subsidence and foundation problems in the Houston, Texas area.(Houston Geological Society., 1962) Weaver, P.; Sheets, M.; Geology of the Gulf Coast and central Texas.No abstract availableItem Active surface faulting in the Houston area, Texas, 1971.(1971) Sheets, M.M.; Houston Geological Society Bulletin.No abstract availableItem Additional archeological survey of the Wallisville Reservoir area, southeast Texas.(1968) Ambler, J.R.;No abstract availableItem Additional benefits from channel improvements(ASCE, New York, NY, USA, 1986) Jensen PA; Kieslich JM;This paper describes techniques used to quantify three types of benefits resulting from enlarging the Houston Ship Channel. These benefit types are vessel casualty reduction, delay reduction and energy savings. The importance of these benefit types is discussed relative to traditional deep-draft benefits in overall project feasibilityItem Additional wastes could turn Buffalo Bayou in giant sewer.(1982) Scarlett, H.; ; Houston PostNo abstract availableItem Aerial radiometric and magnetic survey: Houston National Topographic Map, Texas Gulf Coast.(Geodata International, Incorporated, 1978) Geodata International, Incorporated;No abstract availableItem Aerial videotape survey of the hurricanes Florence and Gilbert impact zone 1988.(Louisiana Geological Survey., 1990) Penland, S.; Westphal, K.A.; McBride, R.A.;No abstract available
