Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: January 1982
John B. Townshend, J.E. Papp, E.A. Sauter, L.Y. Torrence
1982, Open-File Report 82-300-A
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;...
Whole-rock chemical composition of some samples from two drill hole cores in the Capps coal field, Beluga coal area, south-central Alaska
T. K. Hinkley, K. S. Smith, J. L. Peard, M.L. Tompkins
1982, Open-File Report 82-672
Whole-rock chemical analysis was done on samples from drill cores of rocks lying atop and between coal beds in the Beluga coal area, south-central Alaska. The samples were classified as sandstone, siltstone or claystone at time of hand specimen description. Chemical data were compared to those from corresponding rocks from...
Arsenic, nitrate, iron, and hardness in ground water, Chena Hot Springs Road, Steele Creek Road, and Gilmore Trail areas, (T.1N., R.1E., FM), Fairbanks, Alaska
Andrea P. Krumhardt
1982, Open-File Report 82-356
This report presents all data on arsenic, nitrate, iron, and hardness in well water in the Chena Hot Springs Road, Steele Creek Road, and Gilmore Trail area of Fairbanks, Alaska, collected through October 1981. Concentrations range as follows: arsenic - 0 to 5,100 micrograms per liter; nitrate - 0 to...
Preliminary geotechnical and geophysical logs from drill hole 2C-80 in the Capps coal field, Cook Inlet region, Alaska
Alan F. Chleborad, Lynn A. Yehle, Henry R. Schmoll, Cynthia A. Gardner, Larry L. Dearborn
1982, Open-File Report 82-884
The drilling and logging information provided in this report was collected during September 1980 as part of the Energy Lands program of theU.S. Geological Survey.Drill hole 2C-80 is located in the Capps Coal Field, approximately 100 km (62 mi) west of Anchorage, Alaska (fig. 1). The drilling was undertaken to...
Thermal regime of permafrost at Prudhoe Bay, Alaska
A.H. Lachenbruch, J.H. Sass, B.V. Marshall, T. H. Moses Jr.
1982, Open-File Report 82-535
Temperature measurements through permafrost in the oil field at Prudhoe Bay, Alaska, combined with laboratory measurements of the thermal conductivity of drill cuttings permit an evaluation of in situ thermal properties and an understanding of the general factors that control the geothermal regime. A sharp contrast in temperature gradient at...
The Alaska Mineral Resource Assessment Program: Guide to information about the geology and mineral resources of the Ketchikan and Prince Rupert quadrangles, southeastern Alaska
Henry C. Berg
1982, Circular 855
The Ketchikan and Prince Rupert 1-degree by 2-degree quadrangles, which encompass about 16,000 km2 at the south tip of southeastern Alaska, have been investigated by integrated field and laboratory studies in the disciplines of geology, geochemistry, geophysics, and Landsat data interpretation to determine their mineral-resource potential. Mineral deposits in the...

Warren L. Coonrad, editor(s)
1982, Circular 844
This report of accomplishments of the U.S. Geological Survey in Alaska during 1980 contains summary and topical accounts of results of studies in a wide range of topics of economic and scientific interest. In addition, many more detailed maps and reports are included in the lists of references cited for...
Habitat suitability index models: Cutthroat trout
Terry J. Hickman, Robert F. Raleigh
1982, FWS/OBS 82/10.5
Cutthroat trout, Salmo clarki, are a polytypic species consisting of several geographically distinct forms with a broad distribution and a great amount of genetic diversity (Hickman 1978; Behnke 1979). Behnke (1979) recognized 13 extant subspecies: Coastal cutthroat (S. c. clarki) in coastal streams from Prince William Sound, Alaska to the...
Use of microcomputer in mapping depth of stratigraphic horizons in National Petroleum Reserve in Alaska
Thomas G. Payne
1982, Open-File Report 82-1054
REGIONAL MAPPER is a menu-driven system in the BASIC language for computing and plotting (1) time, depth, and average velocity to geologic horizons, (2) interval time, thickness, and interval velocity of stratigraphic intervals, and (3) subcropping and onlapping intervals at unconformities. The system consists of three programs: FILER, TRAVERSER, and...
