R. D. Nason
1981, Earthquake Information Bulletin (USGS) (13) 40-42
Seventy-five years ago on April 18, 1906, the most devastating earthquake in United States history occurred in northern California. This earthquake, which occurred at 5:2 in the morning just as the dawn was breaking, came from rupture of the San Andreas fault from San Juan Bautista (near Hollister) northqard for...

Strains of infectious hematopoietic necrosis (IHN) virus may be identified by structural protein differences
J.C. Leong, Ya Li Hsu, H. Mark Engelking, Daniel M. Mulcahy
D. P. Anderson, editor(s)
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...

Variations in the correlation of body size with concentrations of Cu and Ag in the bivalve Macoma balthica
Carol R. Strong, Samuel N. Luoma
1981, Canadian Journal of Fisheries and Aquatic Sciences (38) 1059-1064
The relationship between body size and concentrations of Cu and Ag varied from strongly positive to strongly negative in four populations of the bivalve Macoma balthica in San Francisco Bay. The correlations appeared to be influenced by the degree of enrichment in tissues, size-dependent differences and seasonal variations in growth rate, and...
Introduction and summary: Chlorinated hydrocarbons as a factor in the reproduction and survival of lake trout (Salvelinus namaycush) in Lake Michigan
Wayne A. Willford, Roger A. Bergstedt, William H. Berlin, Neal R. Foster, Robert J. Hesselberg, Michael J. Mac, Dora R. May Passino, Robert E. Reinert, Donald V. Rottiers
1981, Book chapter, Chlorinated hydrocarbons as a factor in the reproduction and survival of lake trout (Salvelinus namaycush) in Lake Michigan
Although lake trout (Salvelinus namaycush) were considered extinct in Lake Michigan by the mid 1950's, control of the parasitic sea lamprey (Petromyzon marinus) and extensive restocking resulted in an abundance of hatchery-produced lake trout in the lake by the early 1970's. However, no naturally produced yearling or older lake trout...

Toxicity of six bird control chemicals to aquatic organisms
L. L. Marking, J. H. Chandler Jr.
1981, Bulletin of Environmental Contamination and Toxicology (26) 705-716
The U.S. Fish and Wildlife Service (FWS) has supported research on control methods for nuisance birds, mammals, plants, and fish. Although chemical agents have shown great promise, resource managers and regulatory agencies must be assured that these materials are safe to man and the environment. Standardized toxicity tests are conducted...
Magnetic effects of maghemitization of oceanic crust
M. Prevot, A. Lecaille, Edward A. Mankinen
1981, Journal of Geophysical Research B: Solid Earth (86) 4009-4020
Both theoretical considerations and available experimental results indicate that magnetic effects of maghemitization are strongly dependent on the grain size of the originally unoxidized titanomagnetite. Maghemitization of single‐domain titanomagnetite results in a decrease in coercivity, an increase in susceptibility, and a large decrease in Q ratio. Maghemitization of multidomain titanomagnetite results in...
The occurrence of chlorine in serpentine minerals

1981, Contributions to Mineralogy and Petrology (76) 17-23
Partially serpentinized dunites containing small amounts of Chlorine (< 0.5%) from Dumont, Quebec, and Horoman, Hokkaido, Japan, and one containing less than 0.05% Chlorine from Higashi-Akaishi-Yama, Ehime, Japan have been examined using the electron probe microanalyzer and scanning transmission electron microscope with X-ray analytical capabilities. Chlorine was found together with...
Food of the Pacific white-sided dolphin, Lagenorhynchus obliquidens, Dall's porpoise, Phocoenoides dalli, and northern fur seal, Callorhinus ursinus, off California and Washington

1981, Fishery Bulletin (78) 951-959
Our knowledge of the feeding habits of the Pacific white-sided dolphin, Lagenorhynchus obliquidens, and the Dall's porpoise, Phocoenoides dalli, is based on examination of the stomach contents of stranded animals, animals accidentally taken in commercial fishing gear, those taken in the western Pacific commercial fishery, and animals that died during capture...
Simulative models for the analysis of ground-water flow in Vekol Valley, the Waterman Wash area, and the Bosque area, Maricopa and Pina Counties, Arizona
D. T. Matlock
1981, Open-File Report 82-77
Simulative ground-water flow models for Vekol Valley, the Waterman Wash area, and the Bosque area were developed for use in evaluating alternatives for developing a ground-water supply for the Ak-Chin Indian Community. The hydraulic properties of the basin-fill deposits used in the models were estimated primarily from aquifer tests made...
Seepage study of the Sevier River and the Central Utah, McIntyre, and Leamington Canals, Juab and Millard Counties, Utah

1981, Open-File Report 81-820
A study of the gains or losses of the Sevier River and the Central Utah, McIntyre, and Leamington Canals in the Leamington area, in Juab and Millard Counties, Utah, was made to determine changes in those reaches. Three to seven sets of seepage measurements made during 1980 were used in...

1981, Open-File Report 80-1179
The potentiometric surface of the Wilcox-Carrizo aquifer in central northwestern Louisiana is shown by contours using data collected from 1960 to 1980. The aquifer is not affected by regional water-level declines as no large pumping centers have been developed. Seasonal water-level fluctuations in wells are generally less than 10 feet...
