Decline in a population of spectacled eiders nesting on the Yukon-Kuskokwim Delta, Alaska
Craig R. Ely, Christian Dau, Christopher Babcock
1994, Northwestern Naturalist (75) 81-87
The number of spectacled eiders nesting on two study areas near the Kashunuk River, on the central Yukon-Kuskokwim (Y-K) Delta, Alaska, declined by over 75% in the last 20 years. Nesting densities have remained low, but have not significantly declined since 1985. There has been no decrease in the reproductive...
Emperor goose (Chen canagica)
Margaret R. Petersen, Joel A. Schmutz, R.F. Rockwell
A. Poole, F. Gill, editor(s)
1994, Birds of North America 97
Early naturalists exploring western Alaska were intrigued to find a stocky, blue-gray species of coastal goose unique to that area and nearby Russia. As E. W. Nelson (1887) wrote, "Among the various species of birds more or less peculiar to Alaska this goose is perhaps the most noteworthy." The Emperor...
Functional response of wolves preying on barren-ground caribou in a multiple-prey ecosystem
B.W. Dale, Layne G. Adams, R.T. Bowyer
1994, Journal of Animal Ecology (63) 644-652
1. We investigated the functional response of wolves (Canis lupus) to varying abundance of ungulate prey to test the hypothesis that switching from alternate prey to preferred prey results in regulation of a caribou (Rangifer tarandus) population at low densities. 2. We determined prey selection, kill rates, and prey abundance...
Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals
A. Keith Miles, Susan Hills
1994, Marine Pollution Bulletin (28) 456-458
Elevated levels of cadmium in Pacific walrus (Odobenus rosmarus divergens) and northern fur seals (Callorhinus ursinus) have been reported in populations from the Bering Sea (Goldblatt & Anthony, 1983; Taylor et al., 1989). Russian and US authorities are concerned because of the possible health hazards from consuming pinniped meat harvested...
Organochlorine pesticides, chlorinated dioxins and furans, and PCBs in peregrine falcon Falco peregrinus eggs from the Kola peninsula, Russia
Charles J. Henny, S.A. Ganusevich, F.P. Ward, T.R. Schwartz
B-U. Meyburg, R.D. Chancellor, editor(s)
1994, Book chapter, Raptor Conservation Today. Proceedings of the IV World Conference on Birds of Prey and Owls, Berlin, Germany, 10-17 May 1992
Nesting of a bog-associated population of mlgfatory Peregrine Falcons, Falco peregrinus, along the Ponoy River depression, Kola Peninsula, Russia, has been studied since 1977. In 1987 91 production rates averaged 1.94 young per active nest and the number of breeding pairs increased from 4 to 10. In 1991, most eyrie...
Seismic images of the Brooks Range fold and thrust belt, Arctic Alaska, from an integrated seismic reflection/refraction experiment
A. Levander, G. S. Fuis, E. S. Wissinger, W. J. Lutter, J. S. Oldow, Thomas E. Moore
1994, Tectonophysics (232) 13-30
We describe results of an integrated seismic reflection/refraction experiment across the Brooks Range and flanking geologic provinces in Arctic Alaska. The seismic acquisition was unusual in that reflection and refraction data were collected simultaneously with a 700 channel seismograph system deployed numerous times along a 315 km profile. Shot records...
Geology of the conterminous United States at 1:2,500,000 scale; a digital representation of the 1974 P.B. King and H.M. Beikman map
Paul G. Schruben, Raymond E. Arndt, Walter J. Bawiec
1994, Data Series 11
This CD-ROM contains a digital version of the Geologic Map of the Conterminous United States compiled by Philip B. King and Helen M. Beikman of the U.S. Geological Survey. It excludes Alaska and Hawaii. The map was originally published in 1974 at a scale of 1:2,500,000. Although the digitized map...

Warren J. Nokleberg, Leonid M. Parfenov, James W.H. Monger, Boris B. Baranov, Stanislav G. Byalobzhesky, Thomas K. Bundtzen, Tracey D. Feeney, Kazuya Fujita, Steven P. Gordey, Arthur Grantz, Alexander I. Khanchuk, Boris A. Natal’in, Lev M. Natapov, Ian O. Norton, William W. Patton Jr., George Plafker, David W. Scholl, Sergei D. Sokolov, Gleb M. Sosunov, David B. Stone, Rowland W. Tabor, Nickolai V. Tsukanov, Tracy L. Vallier, Koji Wakita
1994, Open-File Report 94-714
The companion tectonostratigraphic terrane and overlap assemblage of map the Circum-North Pacific presents a modern description of the major geologic and tectonic units of the region. The map illustrates both the onshore terranes and overlap volcanic assemblages of the region, and the major offshore geologic features. The map is the...
Development of a digital land cover data base for the Selawik National Wildlife Refuge
Carl J. Markon, William Kirk
1994, Open-File Report 94-627
Digital land cover and terrain data of the Selawik National Wildlife Refuge were produced by the U.S. Geological Survey's (USGS) Earth Resources Observation Systems Alaska Field Office for the U.S. Fish and Wildlife Service. These and other environmental data were incorporated into a Fish and Wildlife Service geographic information system...
Depositional framework and regional correlation of pre-Carboniferous metacarbonate rocks of the Snowden Mountain area, central Brooks Range, Northern Alaska
Julie A. Dumoulin, A. G. Harris
1994, Professional Paper 1545
This report describes lithofacies, conodont biostratigraphy and biofacies, and depositional environments of Proterozoic(?) through Devonian metacarbonate rocks in the Snowden Mountain area. These rocks are correlated with successions on the Seward Peninsula and across the Brooks Range. Lithologic and paleobiogeographic data suggest that these successions formed along a single continental...
