Hydrologic conditions at the Idaho National Engineering Laboratory, Idaho, emphasis: 1974-1978
Jack T. Barraclough, Barney D. Lewis, Rodger G. Jensen
1981, Open-File Report 81-526
The Idaho National Engineering Laboratory (INEL) site covers about 890 square miles of the eastern Snake River Plain and overlies the Snake River Plain aquifer. Low concentrations of aqueous chemical and radio-active wastes have been discharged to shallow ponds and to shallow or deep wells on the site since 1952....
Plankton studies in San Francisco Bay; I, Chlorophyll distributions and hydrographic properties, July 1977-December 1979
Andrea E. Alpine, James E. Cloern, Brian E. Cole
1981, Open-File Report 81-213
This report summarizes the distribution of phytoplankton biomass and selected hydrographic properties measured in the San Francisco Bay Estuary, on a near-monthly basis, from July 1977 through December 1979. Parameters measured were: chlorophyll a, phaeopigments, in-vivo fluorescence, turbidity, size distribution of phytoplankton, salinity and temperature. (USGS)...
Determination of pentachlorophenol in water and aquifer sediments by high-performance liquid chromatography
D.F. Goerlitz
1981, Open-File Report 82-124
Methods for the determination of pentachlorophenol (PCP) in water and aquifer sediments are presented. Reverse-phase high-performance liquid chromotography employing ion suppression and gradient elution is used. PCP can be determined directly in water at a lower limit of detection Of 0.2 micrograms per liter. For extracts of sediment, PCP can...
Time-of-travel studies for the Little Androscoggin River, Maine
William J. Nichols, Barry M. Reed, Fred W. Greenlaw
1981, Open-File Report 81-640
Time-of-travel studies were conducted at flow durations of 20, 80, and 95 percent on the Little Androscoggin River from South Paris to Auburn, Maine. The river is about 29.3 miles long, and drains an area of about 354 square miles at its mouth.Traveltimes were determined by tracing the movement of...
Plankton studies in San Francisco Bay; II, Phytoplankton abundance and species composition, July 1977-December 1979
Raymond L. J. Wong, James E. Cloern
1981, Open-File Report 81-214
Data are presented on the phytoplankton species composition and abundance in San Francisco Bay from July 1977 through December 1979. Phytoplankton identification and enumerations were made at selected stations. Sample collections were made at selected stations in the main channel of the Bay from Rio Vista on the Sacramento River...
Birds of the St. Croix River valley: Minnesota and Wisconsin
Craig A. Faanes
1981, North American Fauna 73
The St. Croix River Valley encompasses nearly 11,550 km2 in east-central Minnesota and northwestern Wisconsin. A wide range of habitats are available for birds including upland oak, lowland deciduous, maple-basswood, lowland and upland coniferous forests, natural basin wetlands, and grasslands. Situated in the north-central region of the United States, the...
Bedded Precambrian iron deposits of the Tobacco Root Mountains, southwestern Montana
H. L. James
1981, Professional Paper 1187
Bedded deposits of iron-formation are minor components of the thoroughly metamorphosed and deformed Precambrian rocks that make up the core of the Tobacco Root Mountains. The rocks are Archean in age; they predate a major Precambrian orogeny that affected all of southwestern Montana about 2,750 m.y. ago. The principal bed...
