1981, Conference Paper, Fish biologics: Serodiagnostics and vaccines (Developments in biological standardization, volume 49)
The development of an effective vaccine to infectious hematopoietic necrosis virus (IHNV) in fish requires a knowledge of the virus serotypes in nature. At least two serotypes were found among three IHNV strains (12). Attempts in our laboratory to extend this study with additional virus strains by classical immunological techniques...
Two oil types on North slope of Alaska: Implications for exploration
L. B. Magoon, George E. Claypool
1981, American Association of Petroleum Geologists Bulletin (65) 644-652
Forty oil samples from across the North Slope of Alaska have been analyzed by the U.S. Bureau of Mines and the U.S. Geological Survey. Results of these analyses suggest two separate genetic oil types. The first, the Simpson-Umiat oil type, occurs in reservoir rocks of Cretaceous and Quaternary age and...
Geology and geochemistry of gas-charged sediment on Kodiak Shelf, Alaska
M. A. Hampton, K.A. Kvenvolden
1981, Geo-Marine Letters (1) 141-147
Methane concentrations in some sediment cores from the Kodiak Shelf and adjacent continental slope increase with depth by three or four orders of magnitude and exceed the solubility in water at ambient conditions. Acoustic anomalies in seismic-reflection records imply that methane-rich sediment is widespread. Molecular composition of hydrocarbon gases and...
Geochemical evidence for a Brooks Range mineral belt, Alaska
S.P. Marsh, J. B. Cathrall
1981, Journal of Geochemical Exploration (15) 367-380
Geochemical studies in the central Brooks Range, Alaska, delineate a regional, structurally controlled mineral belt in east—west-trending metamorphic rocks and adjacent metasedimentary rocks. The mineral belt extends eastward from the Ambler River quadrangle to the Chandalar and Philip Smith quadrangles, Alaska, from 147° to 156°W. longitude, a distance of more...
Geochemical prospecting for hydrocarbons in the outer continental shelf, Southern Bering Sea, Alaska
K.A. Kvenvolden, T.M. Vogel, J.V. Gardner
1981, Journal of Geochemical Exploration (14) 209-219
This geochemical survey is based on 20 stations located on the outer continental shelf of the southern Bering Sea in an area of 30,000 km2 that includes St. George basin. Hydrocarbon gases from sediment samples recovered by gravity coring at each of the stations were analyzed by gas chromatography. Data are...

M. A. Fisher
1981, Geological Society of America Bulletin (92) 19-30
A positive magnetic anomaly extends discontinuously from the south side of the Copper River basin, along the southeast side of Cook Inlet and Shelikof Strait, and southwestward from Kodiak Island to near Sutwik Island. Regionally, this anomaly parallels the Border Ranges fault and...

Seismic evidence for an extensive gas-bearing layer at shallow depth, offshore from Prudhoe Bay, Alaska
G. Boucher, E. Reimnitz, E. Kempema
1981, Cold Regions Science and Technology (4) 63-71
High-resolution seismic reflection data, recorded offshore from Prudhoe Bay, Alaska, were processed digitally to determine the reflectivity structure of the uppermost layers of the seafloor. A prominent reflector, found at 27 m below the mud line (water depths 7-9 m), has a negative reflection coefficient greater than 0.5. The large...
K-Ar ages on intrusive and altered zones in the Chignik and Sutwik Island quadrangles: A section in The United States Geological Survey in Alaska: Accomplishments during 1979
Frederic H. Wilson
1981, Report, The United States Geological Survey in Alaska: Accomplishments during 1979 (Circular 823-B)
Continued K-Ar dating of intrusive rocks and hydrothermal alteration zones in the Chignik and Sutwik Island quadrangles of the Alaska Peninsula, supplemental to that by Wilson, Detterman, and Silberman (1978) and Wilson (1978), has refined our knowledge of the ages of the igneous rocks and clarified relations between altered zones...
Strain accumulation across the Denali fault in the Delta River canyon, Alaska
J.C. Savage, M. Lisowski, W.H. Prescott
1981, Journal of Geophysical Research Solid Earth (86) 1005-1014
Deformation along the Denali fault in the Delta River canyon was determined from geodetic surveys in 1941/1942, 1970, 1975, and 1979. The data were best for the 1975–1979 interval; in that period the average strain accumulation was essentially pure right lateral shear at a rate of 0.6 ± 0.1 μrad/a...

This report is a digest of information furnished by Federal agencies conducting sedimentation investigations on 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 conterminous United States, Alaska,...
Transverse tectonic boundaries near Kodiak Island, Alaska
M. A. Fisher, T.R. Bruns, Roland E. von Huene
1981, Geological Society of America Bulletin (92) 10-18
Transverse tectonic boundaries exist at the northeast and southwest ends of the Kodiak islands, so that the Aleutian arc-trench system is longitudinally segmented in this area. Evidence for the transverse boundaries includes alignments of such geologic features as offset volcanic lineations, terminations of...
Petroleum geology of Cook Inlet basin: An exploration model
Leslie B. Magoon, George E. Claypool
1981, American Association of Petroleum Geologists Bulletin (65) 1043-1061
Oil exploration commenced onshore adjacent to lower Cook Inlet on the Iniskin Peninsula in 1900, shifted with considerable success to upper Cook Inlet from 1957 through 1965, then returned to lower Cook Inlet in 1977 with the COST well and Federal OCS sale. Lower Cook Inlet COST No. 1 well,...
Drug immobilization of walrus (Odobenus rosmarus)
D.P. DeMaster, J.B. Faro, J. A. Estes, James Taggart, C. Zabel
1981, Canadian Journal of Fisheries and Aquatic Sciences (38) 365-367
Five out of nine walrus (Odobenus rosmarus) were successfully immobilized at Round Island, Alaska, in May of 1978 by combinations of phencyclidine hydrochloride and acepromazine hydrochloride. A crossbow was an effective delivery technique. Walruses that had recently hauled out were more suitable for immobilization than well-rested animals. Care was taken...

Faulting in outer continental shelf of southern Bering Sea
James V. Gardner, Tracy L. Vallier
1981, American Association of Petroleum Geologists Bulletin (65) 1568-1573
Synthesis of more than 10 000 line-km of high-resolution seismic data indicates the distribution, types, and trends of faults present on the outer continental shelf of the southern Bering Sea. Faults are classified into three types as to whether they 1) offset the sea floor (surface fault), 2) show less...

R. E. Hunter, D.R. Thor, M.L. Swisher
1981, Geologie en Mijnbouw (61) 49-62
Sonographs and bathymetric profiles from water depths less than 15m in the Nome-Solomon, Port Clarence, and Yukon Delta areas of the Alaskan Bering Sea coast show features generated by waves, currents, and drifting ice. The surficial sediments in the Nome-Solomon and Port Clarence areas range in grain size from sand...
Observations of wing-feather molt and summer feeding ecology of Steller's Eiders at Nelson Lagoon, Alaska
Margaret R. Petersen
1980, Wildfowl (31) 99-106
The population size, moult chronology, food habits, and feeding behaviour of Steller's Eiders Polysticta stelleri were studied at Nelson Lagoon, Alaska from May to October 1977. Sub-adults were flightless from late July to late August and the adult males were flightless from late August to mid September. Adult females were...

1980, Pesticides Monitoring Journal (13) 145-149
During 1975-77, 168 bald eagles (Haliaeetus leucocephalus) found moribund or dead in 29 states were analyzed for organochlorine pesticides and polychlorinated biphenyls (PCBs); 32 specimens from 13 states were analyzed for polybrominated biphenyls (PBBs). PCBs were present in 166 bald eagle carcasses and DDE was found in 165. TDE and...
Paleolimnology of two lakes in the Klutlan Glacier region, Yukon Territory, Canada
J.P. Bradbury, M.C. Whiteside
1980, Quaternary Research (14) 149-168
Lakes developed on progressively younger end moraines of the Klutlan Glacier were initially assumed to have originated shortly after moraine emplacement and to have persisted to the present. Limnological differences between lakes on old vs young moraines were thought to result from limnological maturation within the lakes and ponds themselves...

1980, Sedimentary Geology (26) 157-177
The seafloor of the central part of lower Cook Inlet, Alaska, is characterized by the presence of different sizes and types of bedforms. The bedforms in the sandy sediments include straight-crested to sinuous to lunate ripples, small, medium, and large sand waves, sand ridges, sand ribbons, and sand patches. In...
