Clay mineralogy of Devonian shales in the Appalachian Basin
John W. Hosterman, Sallie I. Whitlow
1981, Open-File Report 81-585
A study of the clay mineralogy of the Devonian black shales of the Appalachian basin was undertaken to help predict areas for potential gas resources. More than 2,100 samples from 84 drill holes representing 11 shale units were analyzed for clay mineralogy or whole—rock mineralogy or both. Approximately 1,300 samples...
Mean annual streamflow of selected drainage basins in the coal area of southeastern Montana
Rodger F. Ferreira
1981, Water-Resources Investigations Report 81-61
Streamflow characteristics of drainage basins within the Fort Union coal region of southeastern Montana were estimated to provide premining data for evaluating the future effects of mining on the environment. Estimated annual mean streamflow at 22 data-collection stations for water years 1975-77 ranged from 0 to 887 cubic feet per...
Appearance and water quality of turbidity plumes created by dredging in Tampa Bay, Florida
Carl R. Goodwin, D.M. Michaelis
1981, Open-File Report 81-541
Turbidity plumes in Tampa Bay, Florida, were monitored during ship-channel dredging operations from February 1977 to August 1978 to document plume appearance and water quality, evaluate plume influence on the characteristics of Tampa Bay water, and provide a basis for transferring the information to other areas having generally similar sediment,...
Distribution of benthic chlorophyll in San Francisco Bay, California, February 1980 - February 1981
Janet Kay Thompson, Frederic H. Nichols, Sally M. Wienke
1981, Open-File Report 81-1134
Benthic microalgae biomass (chlorophyll a) data from San Francisco Bay are presented for the period February 1980 through February 1981. Benthic chlorophyll a was sampled throughout the bay (maximum of 54 stations) at bimonthly intervals and at monthly intervals at up to 14 stations in the southern bay. Ancillary data...
Surface-water resources in the Tooele 2° quadrangle, Utah
Don Price
1981, IMAP 1245
This is one of a series of maps that describe the geology and related natural resources of the Tooele 2° quadrangle. The purpose of this map is to describe on a regional scale the availability and chemical quality of surface water and to guide readers to more detailed site-specific information...
Ground-water levels in selected well fields and in west-central Florida, May 1981
D. K. Yobbi, W. M. Woodham
1981, Open-File Report 81-1106
The water table in the surficial aquifer and the potentiometric surface of the Floridan aquifer in a 1,200-square-mile area in west-central Florida are mapped semi-annually by the U.S. Geological Survey. Maps are based on water levels measured in wells each May to coincide with seasonal low levels and each September...
