1989, Conference Paper, Biotelemetry X: Proceedings of the 10th international symposium on biotelemetry
Satellite telemetry technology has been used during field studies of polar bears in Alaska since 1985. A total of 109 Platform Transmitter Terminals (PTT) have been deployed on free-ranging female polar bears that seasonally inhabit waters adjacent to the Alaskan coast. The PTTs transmitted locational and sensor data to TIROS-N...
Flow and hydraulic characteristics of the Knik-Matanuska River estuary, Cook Inlet, southcentral Alaska
S. W. Lipscomb
1989, Water-Resources Investigations Report 89-4064
A study of the riverine-estuarine reach of the Knik and Matanuska Rivers provided flow and hydraulic data for use in the design of additional bridges over the rivers. Hydraulic analysis is complicated because: (1) the lower reaches of the rivers merge in a complex system of interconnected channels; and (2)...
Seismicity of Alaska 1786-1987
1989, Open-File Report 89-98
This map displays selected epicenters for earthquakes that occurred between 1786 and 1987. Although accurate magnitude values have not been determined for many of the pre-instrumental earthquakes, it is believed that all of the earthquakes presented on this map have magnitudes of 5.0 or greater.Symbols are plotted at epicentral locations,...
Geology and mineral resources of the Port Moller region, western Alaska Peninsula, Aleutian arc: A section in USGS research on mineral resources - 1989: Program and abstracts

1988, Report, USGS research on mineral resources - 1989: Program and abstracts (Circular 1035)
Geologic mapping of the Port Moller, Stepovak Bay, and Simeonof Island quadrangles was begun under the auspices of the Alaska Mineral Resource Assessment Program (AMRAP) in 1983 . Two important mineral deposits are located in the Port Moller quadrangle; the Pyramid prospect is the largest copper porphyry system in the...
Use of a portable electric barrier to estimate Chinook salmon escapement in a turbid Alaskan river
A. Palmisano, C. V. Burger
1988, North American Journal of Fisheries Management (8) 475-480
We developed a portable electric barrier to aid in the capture of adult chinook salmon Oncorhynchus tshawytscha undergoing spawning migrations up a turbid stream in south-central Alaska. In 1981, we tagged and released 157 chinook salmon after diverting them from the main-stem Killey River into a conventional trap with the aid...
Predation of Karluk River sockeye salmon by coho salmon and char
J.D. McIntyre, R.R. Reisenbichler, J.M. Emlen, R.L. Wilmot, J.E. Finn
1988, Fishery Bulletin (86) 611-616
The number of sockeye salmon, Oncorhynchus nerka, in Alaska's Karluk River (Fig. 1) declined from millions to thousands during the early part of the present century. Rounsefell (1958) discussed alternative explanations for the decline including a general loss offertility ofthe system as the number of salmon carcasses declined, competition, overfishing,...
Neutralizing monoclonal antibodies recognize antigenic variants among isolates of infectious hematopoietic necrosis virus
J. R. Winton, C.N. Arakawa, C.N. Lannan, J. L. Fryer
1988, Diseases of Aquatic Organisms (4) 199-204
eutralizing monoclonal antibodies were developed against strains of infectious hematopoietic necrosis virus (IHNV) from steelhead trout Salmo gairdneri in the Deschutes River of Oregon, chinook salmon Oncorhynchus tshawytscha in the Sacramento River of California, and rainbow trout Salmo gairdneri reared in the Hagerman Valley of Idaho, USA. These antibodies were...
Land cover mapping of the upper Kuskokwim Resource Managment Area using LANDSAT and a digital data base approach
Carl J. Markon
1988, Report
Digital land cover and terrain data for the Upper Kuskokwim Resource Hanagement Area (UKRMA) were produced by the U.S. Geological Survey, Earth Resources Observation Systems Field Office, Anchorage, Alaska for the Bureau of Land Management. These and other environmental data, were incorporated into a digital data base to assist in...

The origin of summit basins on the Aleutian Ridge: Implications for block rotation of an arc massif
E.L. Geist, J.R. Childs, D.W. Scholl
1988, Tectonics (7) 327-341
It is proposed that many summit basins along the Aleutian Arc form from the clockwise rotation of blocks of the arc massif. Summit basins are arc-parallel grabens or half-grabens formed within the arc massif and are commonly located near or along the axis of late Cenozoic volcanism. Geomorphically, the Aleutian...

Habitat Suitability Index Models: Red king crab
Stephen C. Jewett, Christopher P. Onuf
1988, FWS/OBS 82/10.153
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for evaluating habitat of different life stages of red king crab (Paralithodes camtschatica). A model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index...
Paleolimnology of Lake Tubutulik, an iron-meromictic Eocene Lake, eastern Seward Peninsula, Alaska
Kendall A. Dickinson
1988, Sedimentary Geology (54) 303-320
Sideritic lacustrine mudstone was found in drill core from a uranium deposit in the Death Valley area in the eastern part of the Seward Peninsula, Alaska. The precursor sediments for this rock were deposited in an unusual “iron-meromictic” Eocene lake, herein named Lake Tubutulik, which occupied part of the Boulder...
