Organochlorine pesticides, chlorinated dioxins and furans, and PCBs in peregrine falcon Falco peregrinus eggs from the Kola peninsula, Russia
Nesting of a bog-associated population of mlgfatory Peregrine Falcons, Falco peregrinus, along the Ponoy River depression, Kola Peninsula, Russia, has been studied since 1977. In 1987 91 production rates averaged 1.94 young per active nest and the number of breeding pairs increased from 4 to 10. In 1991, most eyrie sites were visited during the egg stage and a 'sample' egg was collected for contam

Seagrasses, dredging and light in Laguna Madre, Texas, U.S.A.
Light reduction resulting from maintenance dredging was the suspected cause of large-scale loss of seagrass cover in deep parts of Laguna Madre between surveys conducted in 1965 and 1974. Additional changes to 1988, together with an analysis of dredging frequency and intensity for different parts of the laguna, were consistent with this interpretation. Intensive monitoring of the underwater light

Quality of surface and ground water in the White Creek and Mossy Creek watersheds, White County, Georgia, 1992-93
Surface- and ground-water quality data were collected and evaluated from streams and wells in the White Creek and Mossy Creek watersheds in White County, Georgia, during three sampling periods in 1992 and 1993, to identify stream reaches and wells affected by nonpoint-source contaminants. Livestock operations in these watersheds account for approximately 9.8 million tons of manure per year, which

Documentation of hydrochemical-facies data and ranges of dissolved-solids concentrations for the northern Atlantic Coastal Plain aquifer system, New Jersey, Delaware, Maryland, Virginia and North Carolina supplement to Professional paper 1404-L
Hydrochemical-facies data and ranges of dissolved- solids concentrations used to construct hydrochemical-facies maps and sections for U.S. Geological Survey Professional Paper 1404-L have not been previously published. In this report, the data are contained on a 3-1/2 high-density diskette in a file presented in American International Standard Code for Information Exchange (ASCII) format. The file

Selected nutrients in stormwater runoff from Davenport, Iowa, 1992
Flow-weighted composite samples of stormwater runoff from areas of different land use in Davenport, Iowa, were collected in the summer and fall of 1992 and analyzed for selected nutrients. Annual constituent loads were estimated for the area drained by the Davenport storm-sewer network. In all cases, the regression-equation estimate of mean annual load is less than the estimate obtained by using t

Sources of trends in water-quality data for selected streams in Texas, 1975-89 water years
Sources of trends in water-quality data for selected streams in Texas for the 1975-89 water years were investigated in this study. The investigation of sources was confined to distinct geographic patterns in the trend indicators for one constituent or for a group of related constituents.
The probable source of trend patterns in nutrients and measures of oxygen in the Trinity River Basin was change

Approximate changes in water levels in wells completed in the Chicot and Evangeline aquifers, 1990-94 and 1993-94, in Fort Bend County and adjacent areas, Texas
Measurements of water levels from wells completed in the Chicot and Evangeline aquifers were used to construct maps showing approximate changes of water levels in Fort Bend County and adjacent areas during 1990-94 and 1993-94.

Geologic history and hydrogeologic setting of the Edwards-Trinity aquifer system, west-central Texas
The Edwards-Trinity aquifer system underlies about 42,000 square miles of west-central Texas. Nearly flat-lying, mostly Comanche (Lower Cretaceous) strata of the aquifer system thin northwestward atop massive pre-Cretaceous rocks that are comparatively impermeable and structurally complex. From predominately terrigenous clastic sediments in the east and fluvialdeltaic (terrestrial) deposits in the

Approximate changes in water levels in wells completed in the Chicot and Evangeline aquifers, 1977-94 and 1993-94, and measured compaction, 1973-93, in the Houston-Galveston region, Texas
This report is one in a series of reports that depict water-level changes since 1977 and compaction of subsurface material since 1973. The report was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, and presents maps showing the approximate changes in water levels in wells completed in the Chicot and Evangeline aquifers, 1977-94 and 1993-94 (f
