Salinity and temperature measurements in San Francisco Bay waters, 1980
L.A. Dedini, L. E. Schemel, M.A. Tembreull
1981, Open-File Report 82-125
Measurements of salinity and temperature in waters of the San Francisco Bay estuarine system are presented. Sampling was conducted at selected locations (stations) and depths over the period between January-December 1980 at approximately two week intervals. Stations were located in deep channels and adjacent shallow water areas from Calaveras Point...
Water-quality data for selected stations in the East Everglades, Florida
Bradley G. Waller
1981, Open-File Report 81-821
The results of water-quality samples collected from April 1978 through April 1980 from three canal stations, four marsh stations, and two ground-water stations within the East Everglades, Dade County, Florida, are tabulated in 37 tables. The major categories of parameters analyzed are field measurements, physical characteristics, macronutrients (carbon, nitrogen, and...
Analysis of Egyptian Geological Survey and Mining Department samples by rapid rock and atomic absorption procedures
Jean S. Kane, Hezekiah Smith
1981, Open-File Report 81-991
A suite of 165 samples from the Egyptian Geological Survey and Mining Department was analyzed for several elements in the Branch of Analytical Laboratories (BAL) of the U.S. Geological Survey by M. Iskander and S. Holyle during training here that focused on rapid-rock analytical procedures and on atomic-absorption spectrometric analyses....
Selected hydrologic and climatologic data from the Prairie Dog Creek Basin, southeastern Montana, water year 1979
Lawrence E. Cary, Joel D. Johnson
1981, Open-File Report 81-412
Hydrologic and climatologic data are being collected in a 19-square-mile (49-square-kilometer) basin in southeastern Montana to provide a base for development, calibration, and verification of a precipitation-runoff model. The study area and data-collection stations within the area are shown on a map. A summary of data collected at each station...
Research and development program; Conservation Division Outer Continental Shelf oil and gas operations; Technical report 1981
John B. Gregory, Charlie E. Smith
1981, Open-File Report 81-704
As a result of recommendations several years ago from the National Academy of Sciences, the University of Oklahoma, and the National Aeronautics and Space Administration (NASA), the U.S. Geological Survey has embarked upon a program of research and development to provide the technological insights needed for its regulatory operations offshore—operations...
Large-scale bedforms in the Platte River downstream from Grand Island, Nebraska; structure, process, and relationship to channel narrowing
K.D. Crowley
1981, Open-File Report 81-1059
The Platte River channel in Nebraska, especially downstream from Grand Island, is characterized by large, periodic, and geometrically distinct bedforms called macroforms. Macroforms have dimensions commensurate with the width and depth of the channel and are emergent at all but the highest flow stages. The encroachment of vegetation on macroforms...
Surface-water quality, Twin Ponies watershed, Pottawattamie and Mills Counties, Iowa
Mark G. Detroy
1981, Open-File Report 81-679
Existing surface-water quality in the Twin Ponies watershed is significantly affected by runoff from agricultural lands that comprise most of the area. Runoff effects include the addition of phosphate, organic nitrogen, fecal bacteria, trace metals, pesticides and notably suspended sediment to streaMflow, because runoff commonly is a transport mechanism for...
Quality of surface water in the coal-mining areas of western Maryland and adjacent areas of Pennsylvania and West Virginia from April 1979 to June 1980
W. W. Staubitz
1981, Open-File Report 81-812
The U.S. Geological Survey is studying the water quality of streams within the Eastern Coal Province. This report contains streamflow, water-quality, and biologic data collected in the North Branch Potomac River basin and in the Maryland portion of the Youghiogheny and Casselman River basins. Data collected from 64 streams from...
