Potentiometric surface of the Floridan Aquifer, Southwest Florida Water Management District, September 1983
G. L. Barr, George R. Schiner
1983, Open-File Report 83-868
Maps of the potentiometric surface of the Floridan aquifer in west-central Florida are prepared semiannually by the U.S. Geological Survey in cooperation with the Southwest Florida Water Management District. Maps for May and September show the potentiometric surface that is close to the annual low or high water level condition...
Water resources data for Hawaii and other Pacific areas, water year 1982: Volume 1. Hawaii
Water Resources Division, U.S. Geological Survey, Salwyn S.W. Chinn, Grace A. Tateishi, Johnson J.S. Yee
1983, Water Data Report HI-82-1
Water resources data for the 1982 water year for Hawaii and other Pacific Areas consist of records of stage, discharge, and water quality of streams and springs; and water levels and water quality in wells. This report, volume 1, contains discharge records for 106 gaging stations; water quality for 11...
Data from sediment studies of the Rio Orinoco, Venezuela, August 15-25, 1982
Carl F. Nordin, R.H. Meade, C.C. Curtis
1983, Open-File Report 83-679
Water and suspended-sediment discharges were measured and bed-material samples were collected during August, 1982, at 9 cross sections along a 800-kilometer reach of the Rio Orinoco. Flows varied from approximately 31,000 to 72,000 cubic meters per second, and sediment discharge varied from approximately 1,600 to 8,000 kilograms per second. The...
Preliminary assessment of the geochemistry and mineral favorability of the postorogenic granites of the southeastern Arabian Shield, Kingdom of Saudi Arabia
John S. Stuckless, G. VanTrump, E. H. Christiansen, C. A. Bush, C. M. Bunker, A.J. Bartel
1983, Open-File Report 83-486
Chemical analyses of samples for 19 postorogenic plutons from the southeastern Arabian Shield show that these rocks have average potassium/rubidium ratios (162) and average rubidium/strontium ratios (11.8) characteristic of highly evolved granites. Most of the analyzed samples are peraluminous. Three plutons are physically similar in terms of shape and megascopic...
Drainage divides, Massachusetts; Westfield and Farmington River basins
Russell A. Gadoury, S. William Wandle Jr.
1983, Open-File Report 82-635
Drainage boundaries for selected subbasins in western Hampshire, western Hampden, and southeastern Berkshire Counties, Massachusetts, are delineated on 15 topographic quadrangle maps at a scale of 1:24,000. Drainage basins are shown for all U.S. Geological Survey data-collection sites and for mouths of major rivers. Drainage basins are shown for the...
Aeromagnetic map and interpretation of geophysical data from the Condrey Mountain Roadless Area, Siskiyou County, California
R.C. Jachens, W.P. Elder
1983, Miscellaneous Field Studies Map 1540-B
The Condrey Mountain Roadless Area lies within the Klamath Mountains geologic province, a province composed of four eastward-dipping imbricate thrust slices or belts consisting predominantly of marine arc-related volcanic and sedimentary rocks, but also including significant amounts of ultramafic and other ophiolitic rocks (Irwin, 1981). From west to east the...
Water resources data, Wyoming, water year 1982
E.S. Denison, J.R. Schuetz, Samuel J. Rucker IV
1983, Water Data Report WY-82-1
Water resources data for the 1982 water year for Wyoming consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 185 gaging stations; stage only...
Maps showing aeromagnetic data and interpretation for the Kalmiopsis Wilderness, southwestern Oregon
Richard J. Blakely, Norman J. Page, Floyd Gray, Lisa Senior, Holly F. Ryan
1983, Miscellaneous Field Studies Map 1240-D
The distinctive magnetic properties of the major rock types in the Kalmiopsis Wilderness of southwestern Oregon facilitate interpretation of aeromagenetic data. The region is composed of tectonic slices of magnetic ultramafic, gabboric, and other ophiolitic rocks faulted against  the realitively nonmagnetic Dothan Formation, the equivalent of the Franciscan Complex of...
Reconnaissance geochemical survey of Al Jurdhawiyah and Wadi al Jarir quadrangles, sheets 25/42 D and 25/42 C, Kingdom of Saudia Arabia
Rashid M. Samater
1983, Open-File Report 83-299
A reconnaissance wadi-sediment geochemical survey was conducted in the Al Jurdhawiyah (sheet 28/42 D) and Wadi al Jarir (sheet 2G/42 C) quadrangles in order to identify anomalies potentially related to mineralized rock. Sieved bulk-sediment fractions and pan concentrates were created from the original samples collected from wadis in the two...
Geologic interpretation of geophysical data for the Wadi al Jarir and Al Jurdhawiyah quadrangles, sheets 25/42 C and D, Kingdom of Saudi Arabia
M. Dean Kleinkopf, J. C. Cole
1983, Open-File Report 83-371
Interpretations of aeromagnetic and gravity data made in support of geologic mapping clearly outline the near-surface shape of Proterozoic granitic units in the Wadi al Jarir (25/42 C) and Al Jurdhawiyah (25/42 D) 1:100,000-scale quadrangles of the northern part of the Arabian Shield. The aeromagnetic data show marked correlation with...
A geochemical profile of Tunalik No. 1 well, National Petroleum Reserve in Alaska
Arthur C. Banet Jr.
1983, Open-File Report 83-627
Plotting recently released organic geochemical data against depth shows that the sedimentary section penetrated at the Tunalik No. 1 well is prone to generate gas. Treatment of fifteen geochemical parameters illustrates the organic quality, quantity, and thermal maturity of well cuttings and core samples. Major maturity indicators suggest that the...
Biology, population structure, and estimated forage requirements of lake trout in Lake Michigan
Gary W. Eck, LaRue Wells
1983, Technical Paper 111
Data collected during successive years (1971-79) of sampling lake trout (Salvelinus namaycush) in Lake Michigan were used to develop statistics on lake trout growth, maturity, and mortality, and to quantify seasonal lake trout food and food availability. These statistics were then combined with data on lake trout year-class strengths and...

John B. Townshend, J.E. Papp, E.A. Sauter, L.Y. Torrence, P.A. Franklin
1983, Open-File Report 83-300-I
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Analyses of elutriates, native water, and bottom material in selected rivers and estuaries in western Oregon and Washington
Gregory J. Fuhrer, Frank A. Rinella
1983, Open-File Report 82-922
Chemical analyses of elutriates, bottom sediment and water samples for selected metals, nutrients and organic compounds including insecticides and herbicides have been made to provide data to determine short-term water quality conditions associated with dredging operations in rivers and estuaries. Between May and December 1980 data were collected as far...
