1984, FWS/OBS 82/10.76
Shrimp support the most valuable seafood industry in the United States (Roedel 1973; National Marine Fisheries Service 1983). The three most important commercial species are the white shrimp (Penaeus setiferus L.), brown shrimp (P. aztecus Ives), and pink shrimp (P. duorarum Burkenroad).

A statistical approach to evaluate the relation of coal mining, land reclamation, and surface-water quality in Ohio
Janet Hren, K. S. Wilson, D.R. Helsel
1984, Water-Resources Investigations Report 84-4117
Base-flow data from 779 sites in Ohio 's coal region were analyzed statistically to relate land use to selected water-quality characteristics. Sites were classified into five categories: unmined (100 percent unmined land), abandoned (50 percent or more abandoned surface mines), reclaimed (50 percent or more reclaimed surface mines), deep-mined (50...
Mineral resource potential maps of the Jerry Peak, Jerry Peak West, and Boulder Creek Wilderness Study Areas, Custer County, Idaho
D. H. McIntyre, F. L. Johnson
1984, Miscellaneous Field Studies Map 1466-C
The U.S. Geological Survey and the U.S. Bureau of Mines made a geological and mineral survey of the Jerry Peak, Jerry Peak West, and Boulder Creek Wilderness Study Areas, Custer County, Idaho, from 1980 through 1983. The area is underlain chiefly by lavas and pyroclastic rocks of the Eocene Challis Volcanics....
Land subsidence in the Santa Clara Valley, California as of 1980
J. F. Poland, R. L. Ireland
1984, Open-File Report 84-818
From 1916 to 1966 in the San Jose area of Santa Clara Valley, California, deficient rainfall and runoff was accompanied by a fourfold increase in groundwater withdrawals. In response the artesian head declined 180-240 ft. The land surface subsided 12.7 ft in San Jose, due to compaction of the fine-grained...

M.A. Chaffee, R. H. Hill, S. J. Sutley
1984, Miscellaneous Field Studies Map 1101-B
The Hoover Wilderness and the adjacent Hoover Extension (East), Hoover Extension (West), and Cherry Creek A Roadless Areas (the adjacent study area) encompass approximately 153,900 acres (241 mi2; 623 km2) in the Inyo, Stanislaus, and Toiyabe Naitonal Forests, Mono and Tuolumne Counties, Calif. These two areas lie along and mostly...
Source, movement, and effects of nitrogen and phosphorus in three ponds in the headwaters of Hop Brook, Marlborough, Massachusetts
John C. Briggs, William D. Silvey
1984, Water-Resources Investigations Report 84-4017
The headwaters of Hop Brook near Marlborough, Massachusetts, contain a series of three in-line ponds--Hager Pond, Brist Millpond, and Carding Millpond--which receive over half of their surface-water inflow as effluent from the Marlborough Easterly Wastewater Treatment Plant. These ponds have a history of summer algal blooms and fish kills. Water...
Geochemical survey of the Lusk Creek Roadless Area, Pope County, Illinois
John S. Klasner, Gordon W. Day
1984, Miscellaneous Field Studies Map 1405-B
The Lusk Creek Roadless Area (Index map) lies along the western edge of the Illinois-Kentucky fluorspar district in which flourite deposits occur as lenticular-type veins emplaced along fult zones or as tratiform-shaped bedding-replacement deposits that occur along fault zones (Grogan and Bradbury, 1967; Trace, 1974). Although mineralogy varies between deposits,...
