A study of trends in dissolved oxygen and fecal coliform bacteria at NASQAN stations
Richard A. Smith, Richard B. Alexander
1982, Open-File Report 82-1019
Most stations in the U.S. Geological Survey's National Stream Quality Accounting Network show no significant trend in either dissolved oxygen concentration or fecal coliform bacteria population for the period October 1974. through October 1981. Of the stations which do show trends, however, most show improved water quality: thirty-one of a...
An oilspill risk analysis for the Mid-Atlantic (proposed sale 76) outer continental shelf lease area
W.B. Samuels, Dorothy Hopkins
1982, Open-File Report 82-27
An oilspill risk analysis was conducted for the mid-Atlantic (proposed sale 76) Outer Continental Shelf (OCS) lease area. The analysis considered: the probability of spill occurrences based on historical trends; likely movement of oil slicks based on a climatological model; and locations of environmental resources which could be vulnerable to...
An atlas of eleven selected aquifers in New York
Roger Milton Waller, Anne J. Finch
1982, Open-File Report 82-553
Water from 11 aquifer systems in New York, excluding Long Island , is used by 2.8 million people. Ten are in areas hydraulically connected with the master stream and have a shallow water table, the 11th is a buried valley system on the Lake Ontario Plain. In all systems, till,...
Water resources program of the U.S. Geological Survey related to agriculture in Louisiana
T.L. Huntzinger
1982, Open-File Report 82-554
Surveillance activities of the U.S. Geological Survey Louisiana District include long-term, hydrologic-data-collection sites that serve a current-purpose, management function and (or) that furnish a data base for interpretative studies. The proposed program for 1982 includes a network of 69 surface-water data sites (continuous gaging stations), 250 flood-data sites (crest-stage stations),...
GLORIA sidescan and seismic data collected by the DESV STARELLA along the continental slope and upper continental rise of the Eastern United States in 1979
Kathryn M. Scanlon
1982, Open-File Report 82-1095
A cruise on the- DESV STARELLA was conducted between October 23. 1979, and November 8, 1979, by the U.S. Geologic.al Survey (USGS) in cooperation with the United Kingdom's Institute of Oceanographic Sciences (IOS). The purpose of the study was to gain an overview of the morphology of large areas of...
Flood of September 16, 1975 in the Guayanilla Valley, Puerto Rico
Karl G. Johnson
1982, Open-File Report 80-1282
This report provides hydrologic and hydraulic information related to the flood of September 16, 1975 in the Guayanilla Valley. The information presented is a compilation of data recovered by the U.S. Geological Survey, and information provided by the residents in the study area....
Continuous water sampling and water analysis in estuaries
L. E. Schemel, L.A. Dedini
1982, Open-File Report 82-551
Salinity, temperature, light transmission, oxygen saturation, pH, pCO2, chlorophyll a fluorescence, and the concentrations of nitrate, nitrite, dissolved silica, orthophosphate, and ammonia are continuously measured with a system designed primarily for estuarine studies. Near-surface water (2-m depth) is sampled continuously while the vessel is underway; on station, water to depths...
Evaluation of the streamflow-data program in Pennsylvania
Herbert N. Flippo Jr.
1982, Water-Resources Investigations Report 82-21
The stream-gaging program in Pennsylvania is subject to budgetary constraints in the next several years. Elimination of those gaging stations that have no current-purpose use and little utility in providing regional flow-characteristic information is the most effective way to reduce costs. The efficient design of a network of gaging stations for obtaining regional information...
