Radio-tracking large wilderness mammals: integration of GPS and Argos technologies
Charles C. Schwartz, Steve M. Arthur
1999, Ursus (11) 261-273
We tested 30 prototype global positioning system (GPS) radiocollars on brown bears (Ursus arctos) over a 3-year period on the Kenai Peninsula, Alaska. Collars were of 2 design types: GPS units with an Argos (Argos Data collection and Location System) satellite uplink (n = 19) and GPS units where the...

The oil and gas resource potential of the Arctic National Wildlife Refuge 1002 area, Alaska
ANWR Assessment Team
1999, Open-File Report 98-34
In anticipation of the need for scientific support for policy decisions and in light of the decade-old perspective of a previous assessment, the USGS has completed a reassessment of the petroleum potential of the ANWR 1002 area. This was a comprehensive study by a team of USGS scientists in collaboration...
Epizootiology of viral hemorrhagic septicemia virus in Pacific herring from the spawn-on-kelp fishery in Prince William Sound, Alaska, USA
P.K. Hershberger, R. M. Kocan, N.E. Elder, T.R. Meyers, J. R. Winton
1999, Diseases of Aquatic Organisms (37) 23-31
Both the prevalence and tissue titer of viral hemorrhagic septicemia virus (VHSV) increased in Pacific herring Clupea pallasi following their introduction into net pens (pounds) used in the closed pound spawn-on-kelp (SOK) fishery in Prince William Sound, Alaska. VHSV was also found in water samples from inside and outside the SOK pounds...

Acute toxicity and sublethal effects of white phosphorus in mute swans, Cygnus olor
D. W. Sparling, D. Day, P. Klein
1999, Archives of Environmental Contamination and Toxicology (36) 316-322
Among the waterfowl affected by white phosphorus (P4) at a military base in Alaska are tundra (Cygnus columbianus) and trumpeter (C. buccinator) swans. To estimate the toxicity of P4 to swans and compare the toxic effects to those of mallards (Anas platyrhynchos), we dosed 30 juvenile mute swans (C. olor) with...
Evaluations of plastic mesh tubes for protecting conifer seedlings from pocket gophers in three western states
Richard M. Engeman, Richard M. Anthony, Victor G. Barnes, Heather W. Krupa, James Evans
1999, Western Journal of Applied Forestry (14) 86-90
The efficacy of plastic mesh tubes for protecting conifer seedlings from pocket gopher damage was evaluated on three national forest lands in three states. In each area, cohorts of 640 protected seedlings and 640 unprotected seedlings (3,840 total) were individually monitored for damage, survival, and growth twice...
Effect of slope and headpond on passage of American shad and blueback herring through simple Denil and deepened Alaska steeppass fishways
Alexander J. Haro, Mufeed Odeh, Theodore Castro-Santos, John Noreika
1999, North American Journal of Fisheries Management (19) 51-58
Passage and transit time of adult upstream-migrant American shad Alosa sapidissima and blueback herring A. aestivalis were investigated in standard Denil and Alaska steeppass fishways with variable slope and headpond under semicontrolled conditions. Percent of American shad passed per unit time (percent passage) increased with temperature, while time required to...

1999, Bulletin 543
quantitative pollen and spore zonation for the Neogene and Quaternary of Yukon, western Northwest Territories and central and northern Alaska has been assembled from seven sections and one borehole. The palynological spectra from 163 samples from these sections were grouped and averaged within the groups to produce twenty-one composite spectra...
Results of the 1999 survey of the reintroduced sea otter population in Washington state
Ronald J. Jameson, Steven J. Jeffries
1999, Report
Fifty-nine sea otters were released off the west coast of the Olympic Peninsula of Washington State during the summers of 1969 and 1970; all had been translocated from Amchitka Island, Alaska. In 1970, 30 otters were released. Surveys to assess the results of this translocation began in 1977. Up to...
Time of day of ovulation by three duck species in subarctic Alaska
Daniel Esler
1999, Condor (101) 422-425
I examined variation in ovulation times of Northern Pintails (Anas acuta), American Wigeon (A. americana), and Lesser Scaup (Aythya affinis) breeding in subarctic Alaskan wetlands. Ovulation times and, by extension, egg-laying times were highly variable in all three species, with ovulations occurring during all hours of the day. Only Lesser...

A new magnetic view of Alaska
R. W. Saltus, T. L. Hudson, G. G. Connard
1999, GSA Today (9) 1-6
A new, publicly available aeromagnetic data compilation spanning Alaska enables analysis of the regional crustal character of this tectonically diverse and poorly understood part of the North American Cordillera. The merged data were upward-continued by 10 km (mathematically smoothed without assumptions about sources) to enhance crustal-scale magnetic features and facilitate...
Time-budgets of Common Murres at a declining and increasing colony in Alaska
Stephani Zador, John F. Piatt
1999, Condor (101) 149-152
We observed Common Murres (Uria aalge) at two breeding sites in lower Cook Inlet, Alaska, to determine whether food availability was reflected in their time-budgets at each colony. Catches of forage fish in nets and relative biomass were greater around a murre colony that has been increasing for the past...
The evolutionary history of steelhead (Oncorhynchus mykiss) along the US Pacific Coast: Developing a conservation strategy using genetic diversity
J.L. Nielsen
1999, ICES Journal of Marine Science (56) 449-458
Changes in genetic variation across a species range may indicate patterns of population structure resulting from past ecological and demographic events that are otherwise difficult to infer and thus provide insight into evolutionary development. Genetic data is used, drawn from 11 microsatellite loci amplified from anadromous steelhead (Oncorhynchus mykiss) sampled...
The epipelagic fish community of Beaufort Sea coastal waters, Alaska
L. E. Jarvela, Lyman K. Thorsteinson
1999, Arctic (52) 80-94
A three-year study of epipelagic fishes inhabiting Beaufort Sea coastal waters in Alaska documented spatial and temporal patterns in fish distribution and abundance and examined their relationships to thermohaline features during summer. Significant interannual, seasonal, and geographical differences in surface water temperatures and salinities were observed. In 1990, sea ice...

Vocalizations of the Kittlitz's Murrelet
Thomas I. van Pelt, John F. Piatt, Gus B. Van Vliet
1999, Condor (101) 395-398
We present the first documentation of Kittlitz's Murrelet (Brachyramphus brevirostris) vocalizations, based on recordings made in Glacier Bay, Alaska, in 1994. We identified two apparently related types of calls: groan and quack. The Kittlitz's Murrelet calls were markedly different from the most common calls of the congeneric Marbled Murrelet (Brachyramphus...

Seismic hazard map of the western hemisphere

1999, Annals of Geophysics (42) 1199-1214
Vulnerability to natural disasters increases with urbanization and development of associated support systems (reservoirs, power plants, etc.). Catastrophic earthquakes account for 60% of worldwide casualties associated with natural disasters. Economic damage from earthquakes is increasing, even in technologically advanced countries with some level of seismic zonation, as shown by the...
Distribution and diurnal behavior of Steller's Eiders wintering on the Alaska Peninsula
M.K. Laubhan, K.A. Metzner
1999, Condor (101) 694-698
We studied the distribution and activities of adult Steller's Eiders (Polysticta stelleri) during winter and spring on a deep-water embayment and a shallow lagoon along the Alaska Peninsula from September 1980 to May 1981. During the remigial molt, eiders were observed on Izembek Lagoon but not on Cold Bay. Following...

1999, Conference Paper, Marine mammals and persistent ocean contaminants: Proceedings of the Marine Mammal Commission Workshop
This working group did not divide into subgroups, and its report consists of a unified document in a format somewhat different than those of the other working groups. The group considered four major topics: (1) projected "new" contaminants of future concern; (2) future trends with contaminants currently known to be...
