Data on ground-water quality with emphasis on radionuclides, Sarasota County, Florida
Horace Sutcliffe, R. L. Miller
1981, Open-File Report 80-1223
A compilation of analytical results are presented for selected radiochemical and chemical characteristics for 200 groundwater samples collected from 92 wells in Sarasota County, Fla. Radium-226 analysis was made on 160 of the water samples and 80 samples equaled or exceeded the 5 picocuries per liter maximum contaminant level established...

James M. Robb, John C. Hampson Jr., John R. Kirby, David C. Twichell
1981, Open-File Report 81-600
Because sediment instability, or slumping, has been identified as a potential hazard to petroleum development of the east-coast Continental Slope, the U.S. Geological Survey, in cooperation with the U.S. Bureau of Land Management, began a detailed study of a segment of the Continental Slope between Lindenkohl and South Toms Canyons...
Phytoplankton productivity, respiration, and nutrient uptake and regeneration in the Potomac River, August 1977 - August 1978
B.E. Cole, D.D. Harmon
1981, Open-File Report 81-700
Rates of phytoplankton productivity, respiration, and nutrient uptake and regeneration are presented. These observations were made on the Potomac River estuary (POTE) during four cruises between August 1977 and August 1978. Four experimental methods were used: carbon uptake using carbon-14, carbon uptake and respiration by a pH method, productivity and...
Map showing bathymetry and aquatic plants of Lake Waramaug, Connecticut
Kenneth P. Kulp
1981, Open-File Report 81-477
The Bathymetry of Lake Waramaug is shown at 5-foot intervals, and the location and identification of significant concentrations of aquatic plants is indicated. The bathymetry shows the lake to be relatively steep-sided and flat-bottomed, with a maximum depth of between 40 and 45 feet. Aquatic plants were confined to the...
