Sediment transport in the Tanana River near Fairbanks, Alaska, 1980-81
R.L. Burrows, P.E. Harrold
1983, Water-Resources Investigations Report 83-4064
Suspended-sediment- and bedload-transport rates for the Tanana River near Fairbanks, Alaska, can be related to water discharge. Annual sediment loads can be computed using these relations. For a site at Fairbanks, the annual loads in 1980 were 22.0 million metric tons of suspended sediment and 272,000 metric tons of bedload;...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: January 1983
John B. Townshend, J.E. Papp, E.A. Sauter, T.K. Cunningham, L.Y. Torrence
1983, Open-File Report 83-300-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;...
New horizons for the national high-altitude photography program
Peter F. Bermel
1983, Pecora VIII Symposium 172-172
The National High-Altitude Photography Program (NHAP) is a multi-Federal agency activity to acquire uniform imagery for the establishment of a national high-altitude photographic data base. Federal agencies participating in NHAP have pooled their resources and consolidated photographic requirements in a systematic 6-year effort that will minimize duplication of photographic...
Intrusive rocks and plutonic belts of southeastern Alaska, U.S.A
David A. Brew, Robert P. Morrell
1983, GSA Memoirs (159) 171-194
About 30 percent of the 175,000-km2 area of southeastern Alaska is underlain by intrusive igneous rocks. Compilation of available information on the distribution, composition, and ages of these rocks indicates the presence of six major and six minor plutonic belts.From west to east, the major belts are: the Fairweather-Baranof belt of...
Wandering terranes in southern Alaska: The Aleutia Microplate and implications for the Bering Sea
Michael S. Marlow, Alan K. Cooper
1983, Journal of Geophysical Research B: Solid Earth (88) 3439-3446
Paleomagnetic and geological data suggest that much of southern Alaska is a collage of tectonostratigraphic terranes which originated in Mesozoic time at paleolatitudes far south of their present position. The time of ‘docking’ of the terranes against cratonic Alaska is critical to defining their amalgamated size and extent during their...
Expendable bubble tiltmeter for geophysical monitoring
J.A. Westphal, M.A. Carr, W.F. Miller, D. Dzurisin
1983, Review of Scientific Instruments (54) 415-418
An unusually rugged highly sensitive and inexpensive bubble tiltmeter has been designed, tested, and built in quantity. These tiltmeters are presently used on two volcanoes and an Alaskan glacier, where they continuously monitor surface tilts of geological interest. This paper discusses the mechanical, thermal, and electric details of the meter,...
Notes on sedimentation activities calendar year 1982
1983, Report
This report is a digest of information furnished by those Federal agencies conducting sedimentation investigations. It includes descriptions of work in progress or planned, important findings, new methods, new publications, laboratory and other research activities, and other pertinent information. The material has been organized by major drainage regions in the...
Tin granites of Seward Peninsula, Alaska
T. Hudson, Joseph G. Arth
1983, Geological Society of America Bulletin (94) 768-790
Seven granite plutons, spatially and genetically related to tin metalization, are exposed in a 170-km-long belt across northwestern Seward Peninsula, Alaska. These plutons are cupolas and epizonal composite stocks that consist of several textural varieties of biotite granite, including medium- to coarse-grained seriate...
Diatom evidence on Wisconsin and Holocene events in the Bering Sea
C. Sancetta, S.W. Robinson
1983, Quaternary Research (20) 232-245
Previous work on surface (modern) sediments has defined diatom species which appear to be good indicators of various oceanographic/ecologic conditions in the North Pacific Ocean and marginal seas. Three long cores from the eastern and northern sides of the Aleutian Basin show changes in species assemblage which can be interpreted...
Holocene history of the estuarine area surrounding Portage, Alaska, as recorded in a 93 m core
S. Bartsch-Winkler, A.T. Ovenshine, R. Kachadoorian
1983, Canadian Journal of Earth Sciences (20) 802-820
A 93 m core obtained at Portage, Alaska records four prograding cycles of estuarine deposition for the past 8230 ± 100 years. Analyses of texture, mineralogy, paleontology, and sedimentary structures enable definition of eight lithologic units. Mineralogic studies show that past and present sedimentation at Portage has been largely mud and sand from...
