Velocity and surface altitude of the lower part of Hubbard Glacier, Alaska, August 1978
R. M. Krimmel, W. G. Sikonia
1986, Open-File Report 86-549
The terminus position and locations of numerous points on the lower part of Hubbard Glacier were determined from 1:58,000 scale vertical aerial photographs taken July 30, 1978 and August 23, 1978. The same surface features were located on each set of photography, allowing displacement during the time interval to be...
Geologic studies in Alaska by the U.S. Geological Survey during 1985
Susan B. Bartsch-Winkler, Katherine M. Reed, editor(s)
1986, Circular 978
This circular contains short reports about many of the geologic studies carried out in Alaska by the U.S. Geological Survey and cooperating agencies in 1985. The topics cover a wide range in scientific and economic interest. Separate bibliographic listings of published reports are included. These listings are: (1) data releases...
Ground-water levels in Alaska, water year 1983
J.O. Brunett
1986, Open-File Report 86-56
Groundwater level data in Alaska are summarized for the 1983 water year for observation wells at which levels are either recorded continuously or measured intermittently. For wells at which water levels are measured semi-annually, 10-year summaries are presented. Water levels for 153 observation wells are shown on graphs and locations...
Bibliographies and location maps of aeromagnetic and aeroradiometric publications for the states west of approximately 104 degrees longitude (exclusive of Alaska and Hawaii)
Patricia L. Hill
1986, Open-File Report 86-525-A
Bibliographies and location maps of selected publications containing aeromagnetic and/or aeroradiometric data have been compiled for each state. These state indexes have been grouped together to form seven open-file reports: four for the conterminous United States (see index map below), one for Alaska and Hawaii, one for Puerto Rico and...
Hydrologic reconnaissance of the Unalakleet River basin, Alaska, 1982-83
C. E. Sloan, D.R. Kernodle, Ronald Huntsinger
1986, Water-Resources Investigations Report 86-4089
The Unalakleet River, Alaska, from its headwaters to the confluence of the Chiroskey River has been designated as a wild river and is included in the National Wild and Scenic Rivers System. Yearly low flow, which occurs during the winter, is sustained by groundwater discharge; there are few lakes in...
Bibliographies and location maps of aeromagnetic and aeroradiometric publications for Puerto Rico and large areas of the conterminous United States
Patricia L. Hill
1986, Open-File Report 86-525-F
Bibliographies and location maps of selected publications containing aeromagnetic and/or aeroradiometric data have been compiled for each state. These state indexes have been grouped together to form seven open-file reports: four for the conterminous United States (see index map below), one for Alaska and Hawaii, one for Puerto Rico and...
Multichannel seismic-reflection data collected in 1980 in the eastern Chukchi Sea
Arthur Grantz, Dennis M. Mann, Steven D. May
1986, Open-File Report 86-405
The U.S. Geological Survey (USGS) collected approximately 2,652 km of 24-channel seismic-reflection data in early September, 1980, over the continental shelf in the eastern Chukchi Sea (Fig. 1). The profiles were collected on the USGS Research Vessel S.P. Lee. The seismic energy source consisted of a tuned array of five...
Sediment transport characteristics of selected streams in the Susitna River Basin, Alaska, October 1983 to September 1984
J. M. Knott, Stephen W. Lipscomb, Terry W. Lewis
1986, Open-File Report 86-424-W
The upper reaches of the Susitna River have been considered for development of a large power generation system for south-central Alaska. This report presents a summary and discussion of sediment and hydraulic data obtained from October 1983 to September 1984 at ten sites on the Susitna, Chulitna, Talkeetna, and Yentna...

Evaluation of Alaskan wetlands for waterfowl
Calvin J. Lensink, Dirk V. Derksen
1986, Conference Paper, Alaska: Regional wetland functions: Proceedings of a workshop held at Anchorage, Alaska, May 28-29, 1986
Few studies have focused specifically on use of Alaskan wetlands by waterfowl. However, substantial information on the values of wetlands is available from studies on individual species or that were conducted for other purposes. Most investigators have found it most effective to classify habitat use on the basis of observed...
Changing climate: Geothermal evidence from permafrost in the Alaskan Arctic
Arthur H. Lachenbruch, B. Vaughan Marshall
1986, Science (234) 689-696
Temperature profiles measured in permafrost in northernmost Alaska usually have anomalous curvature in the upper 100 meters or so. When analyzed by heat-conduction theory, the profiles indicate a variable but widespread secular warming of the permafrost surface, generally in the range of 2 to 4 Celsius degrees during the last...
