Potentiometric surface of Floridan Aquifer, southwest Florida Water Management District and adjacent areas, May 1979
R. M. Wolansky, L. R. Mills, W. M. Woodham, C. P. Laughlin
1979, Open-File Report 79-1255
A May 1979 potentiometric-surface map depicts the annual low water-level period. Potentiometric levels declined 4 to 21 feet between September 1978 and May 1979, in the citrus and farming sections of southern Hillsborough, northern Hardee, southwestern Polk, northwestern DeSoto, and Manatee Counties. Water levels in these areas are widely affected...
Water and sediment measurements in San Francisco Bay, California
Laurence E. Schemel, Andrea E. Alpine, Brian E. Cole, Lee A. Dedini, Elliott C. Spiker
1979, Open-File Report 78-973
Water samples collected in San Francisco Bay, the Gulf of the Farallones, and the delta of the Sacramento and San Joaquin rivers were analyzed for salinity, temperature, partial pressure of carbon dioxide (pCO2), chlorophyll a, alkalinity, particulate organic carbon (POC), and the stable carbon isotope ratio (δ13C) of the POC...
Texture, clay mineralogy, trace metals, and age of cored sediments from the North Atlantic Outer Continental Shelf
Michael H. Bothner, E.C. Spiker, W.M. Ferrebee, D.L. Peeler
1979, Open-File Report 79-842
The concentration of 9 trace metals in sediment cores collected from the Continental Shelf off the northeastern United States are generally uniform with sediment depth and are low compared to average crustal abundances. No evidence for the accumulation of anthropogenic metals was found in these samples.The sediment texture on Georges...
Ground water in Dale Valley, New York
Allan D. Randall
1979, Water-Resources Investigations Report 78-120
Dale Valley is a broad valley segment, enlarged by glacial erosion, at the headwaters of Little Tonawanda Creek near Warsaw , New York. A thin, shallow alluvial aquifer immediately underlies the valley floor but is little used. A deeper gravel aquifer, buried beneath many feet of lake deposits, is tapped...
Columbia Glacier stake location, mass balance, glacier surface altitude, and ice radar data, 1978 measurement year
L.R. Mayo, D.C. Trabant, Rod March, Wilfried Haeberli
1979, Open-File Report 79-1168
A 1 year data-collection program on Columbia Glacier, Alaska has produced a data set consisting of near-surface ice kinematics, mass balance, and altitude change at 57 points and 34 ice radar soundings. These data presented in two tables, are part of the basic data required for glacier dynamic analysis, computer...
System dynamics simulation modeling applied to western coal development environmental impact analysis
R. K. Mark, D. S. Harwood, E. B. Newman, Richard R. Doell
1979, Open-File Report 79-226
This report, which was originally prepared in 1977 as an administrative report, evaluates the Geological Survey's first attempt to use simulation modeling in the environmental impact statement (EIS) process. It discusses the background of the modeling project, evaluates the usefulness of that project to the Northern Powder River Basin regional...
Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, Spring 1977 and Spring 1978
R.K. Gabrysch
1979, Open-File Report 79-334
The purpose of this report, which was prepared in cooperation with the cities of Houston and Galveston, the Harris-Galveston Coastal Subsidence District, and the Texas Department of Water Resources, is to show the altitudes of water levels in wells in the Chicot and Evangeline aquifers in the Houston, Texas, metropolitan...
Preliminary report on the energy resource position of the Republic of Korea
M. J. Bergin
1979, Open-File Report 79-1438
The Republic of Korea has meager resources of energy minerals. Only hydroelectric power and coal were listed as sources of energy indigenous to Korea in the report of the 1967 World Energy Conference. Small reserves of thorium have been estimated and the discovery of uranium was reported in 1977 (A....
Bibliographic supplement to USGS Bulletin 1426; 1975 to June 1979
Wenonah E. Bergquist, Elizabeth J. Tinsley, Valerie S. Upton
1979, Open-File Report 79-1518
This bibliography is a supplement to U.S. Geological Survey Bulletins 1426 (Bergquist, 1976) and 1263 (Heath and Tabacchi, 1968). The titles listed result from work undertaken in cooperation with national agencies partly through technical assistance projects under the auspices of the Agency for International Development, U.S. Department of State; partly...
A plan to study the aquifer system of the Central Valley of California
Gilbert L. Bertoldi
1979, Open-File Report 79-1480
Unconsolidated Quaternary alluvial deposits comprise a large complex aquifer system in the Central Valley of California. Millions of acre-feet of water is pumped from the system annually to support a large and expanding agribusiness industry. Since the 1950's, water levels have been steadily declining in many areas of the valley...
