Hydrologic reconnaissance of the Chilkat River basin, Southeast Alaska; with special reference to the Alaska Chilkat Bald Eagle Preserve
E. F. Bugliosi
1988, Water-Resources Investigations Report 88-4023
The Chilkat River Basin of Alaska is characterized by glaciers, highly dissected mountains with steep-gradient streams, and braided rivers in broad, alluvium-filled valleys. Orographic effects and a wide seasonal range in temperature cause variations in the amount and distribution of precipitation, and thus in the resulting runoff and streamflow. Seeps...
Infectious hematopoietic necrosis virus detected by separation and incubation of cells from salmonid cavity fluid.
D. Mulcahy, W.N. Batts
1987, Canadian Journal of Fisheries and Aquatic Sciences (44) 1071-1075
Infectious hematopoietic necrosis (IHN) virus is usually detected by inoculating susceptible cell cultures with cavity ("ovarian") fluid (CF) from spawning females. We identified additional adult carriers of virus in spawning populations of steelhead trout (Salmo gairdneri) and sockeye salmon (Oncorhynchus nerka) by collecting nonerythrocytic cells from CF samples by low-speed...
Comparison of five techniques for the detection of Renibacterium salmoninarum in adult coho salmon.
R.J. Pascho, D.G. Elliott, R.W. Mallett, D. Mulcahy
1987, Transactions of the American Fisheries Society (116) 882-890
Samples of kidney, spleen, coelomic fluid, and blood from 56 sexually mature coho salmon Oncorhynchus kisutch were examined for infection by Renibacterium salmoninarum by five methods. The overall prevalence (all sample types combined) of R. salmoninarum in the fish was 100% by the enzyme-linked immunosorbent assay, 86% by the combined...
Enzyme-linked immunosorbent assay for a soluble antigen of Renibacterium salmoninarum, the causative agent for salmonid bacterial kidney disease
R.J. Pascho, D. Mulcahy
1987, Canadian Journal of Fisheries and Aquatic Sciences (44) 183-191
A double-antibody enzyme-linked immunosorbent assay (ELISA) for detection of a soluble fraction of Renibacterium salmoninarum was developed from components extracted from the supernatant of an R. salmoninarum broth culture. The Costar® Serocluster™ EIA microplate gave the highest absorbance and signal-to-noise ratios among seven types tested. Including Tween 80 in the...
Trends in spawning populations of Pacific anadromous salmonids
G.W. Konkel, J.D. McIntyre
1987, Fish and Wildlife Technical Report 9
Annual escapement records for 1968-1984 for five species of Pacific salmon-chinook (Oncorhynchus tshawytscha), coho (O. kisutch), sockeye (O. nerka), pink (O. gorbuscha), and chum (O. keta)—and steelhead (Salmo gairdneri) were obtained from published and unpublished sources and organized in a computer database. More than 25,500 escapement records were obtained for...
Summer spawning in the fourhorn sculpin, Myoxocephalus quadricornis, from Alaska
S.R. Goldberg, W. T. Yasutake, R.L. West
1987, Canadian Field-Naturalist (101) 457-457
Histological ovarian analysis indicates summer spawning occurs in Myoxocephalus quadricornis (Fourhorn Sculpin) from Alaska. Previous studies have shown this species spawns during winter in the Baltic Sea; the data presented herein suggests that geographical variation may occur in the timing of spawning of this species....
Tetlin National Wildlife Refuge land cover mapping project users guide
Carl J. Markon
1987, Report
Title III of the Alaska National Interest Lands Conservation Act of 1980 (ANILCA, 1980) established the Tetlin National Wildlife Refuge (TNWR). Section 304 of the Act requires the Secretary of Interior to "prepare, and from time to time revise, a comprehensive conservation plan" for the refuge. Before developing a plan...
Nesting by pomarine jaegers near Barrow, Alaska, 1971
Thomas W. Custer, Frank A. Pitelka
1987, Journal of Field Ornithology (58) 225-230
An estimated 5.7 pairs of pomarine jaegers km -2 (14.8 mi -2) nested near Barrow, Alaska, in 1971. Hatching success of 67 eggs (34 nests) was 57%. Fledging success of 44 nestlings (26 nests) was 32%. An estimated 0.4 young survived to 25 d of age per nesting attempt....
Arctic National Wildlife Refuge, Alaska, Coastal Plain Resource Assessment: Report and recommendation to the Congress of the United States and final legislative environmental impact statement
U.S. Fish and Wildlife Service
1987, Report
The Arctic National Wildlife Refuge, in the northeastern corner of Alaska, was first established as the Arctic National Wildlife Range by Public Land Order 2214 in 1960, for the purpose of preserving unique wildlife, wilderness, and recreational values. The original 8.9-millionacre Range was withdrawn from all forms of appropriation under...
Checklist of vertebrates of the United States, the U.S. territories, and Canada
Richard C. Banks, Roy W. McDiarmid, Alfred L. Gardner
1987, Resource Publication 166
On 30 January 1980 the Policy Group of the 1978 Interagency Agreement on Classifications and Inventory established a work group on fish and wildlife species names. The participating agencies were the Fish and Wildlife Service, Forest Service, Bureau of Land Management, Geological Survey, and Soil Conservation Service. The...
Accretion of southern Alaska
John W. Hillhouse
1987, Tectonophysics (139) 107-122
Paleomagnetic data from southern Alaska indicate that the Wrangellia and Peninsular terranes collided with central Alaska probably by 65 Ma ago and certainly no later than 55 Ma ago. The accretion of these terranes to the mainland was followed by the arrival of the Ghost Rocks volcanic assemblage at the...
Tables showing analyses of semiquantitative spectrometry and atomic-absorption spectrophotometry of rock samples collected in the Ugashik, Bristol Bay, and western part of the Karluk quadrangles, Alaska
Frederic H. Wilson, Richard M. O’Leary
1987, Open-File Report 87-419
The accompanying tables list chemical analyses of 337 rock samples that were collected in 1979, 1980, and 1981 in conjunction with geologic mapping in the Ugashik, Bristol Bay, and part of Karluk quadrangles. This work was conducted under the auspices of the Alaska Mineral Resource Assessment Program (AMRAP). This report...
Hydrologic unit maps
Paul R. Seaber, F. Paul Kapinos, George L. Knapp
1987, Water Supply Paper 2294
A set of maps depicting approved boundaries of, and numerical codes for, river-basin units of the United States has been developed by the U.S . Geological Survey. These 'Hydrologic Unit Maps' are four-color maps that present information on drainage, culture, hydrography, and hydrologic boundaries and codes of (1) the 21...
Field surveying and topographic mapping in Alaska: 1947-83
Robert C. Foley
1987, Circular 991
The U.S. Geological Survey's earliest presence in Alaska dates back to 1889. A decade later, topographic mapping became an integral part of the Geological Survey's Alaska program, mostly as reconnaissance-type mapping and special-purpose mapping of specific sites. It was not until after World War II that the Survey's Alaska topographic...
