J. Burke, D. Mulcahy
1983, Journal of Fish Diseases (6) 543-547
Pools of brain, kidney, spleen, liver and gut tissues from several rainbow trout, Salmo gairdneri Richardson, and whole sockeye salmon, Oncorhynchus nerka (Walbaum), fry were homogenized with a known amount of infectious haematopoietic necrosis virus (IHNV). Virus was also added to ovarian fluids and sera pooled from several rainbow trout....

Margaret R. Petersen
1983, The Condor (85) 367-368
Estuaries along the north side of the Alaska Peninsula provide essential habitat for most of the American population of Emperor Goose (Chen canagica) during migration (Petersen and Gill 1982). Most of the population passes through Nelson Lagoon in spring and fall, with over 40,000 birds recorded there (Gill et al...

Daniel M. Mulcahy, Ronald J. Pascho, C.K. Jenes
1983, Journal of Fish Diseases (6) 321-330
In a study of the possible role of waterborne infectious haematopoietic necrosis virus in transmission of the disease among spawning sockeye salmon, Oncorhynchus nerka (Walbaum), both infection rates and virus titres were higher in fish held at high density in a side channel than in fish in the adjacent river....
An isolated population of small Canada geese on Kaliktagik Island, Alaska
Scott A. Hatch, Martha A. Hatch
1983, Wildfowl (34) 130-136
Recently we discovered that a small form of the Canada Goose Branta canadensis breeds on Kaliktagik Island, one of the Semidi Islands, about 80 km south of the Alaska Peninsula near longitude 157°W (Figure 1). The unexpected occurrence of geese on this oceanic island and the possibility that they are...

1983, Water-Resources Investigations Report 81-1182
Lake Washington, in the midst of the greater Seattle metropolitan area of the Puget Sound region (fig. 1), is an exceptional commercial, recreational, and esthetic resource for the region . In the past 130 years, Lake Washington has been changed from a " wild " lake in a wilderness setting...
Impact of changes in land use on the ground-water system in the Sequim-Dungeness Peninsula, Clallam County, Washington
B. W. Drost
1983, Water-Resources Investigations Report 83-4094
A digital-computer model was developed to simulate three-dimensional ground-water flow in aquifers underlying the Sequim-Dungeness peninsula, Clallam County, Washington. Analysis using the model shows that leakage from irrigation ditches is the area 's most important source of ground-water recharge. Termination of the irrigation system would lead to lower heads throughout...
Ground water in the northeast part of Twentynine Palms Marine Corps Base, Bagdad area, California
J. H. Koehler
1983, Water-Resources Investigations Report 83-4053
The hydrologic characteristics of the Bagdad area, in the northeast part of Twentynine Palms Marine Corps Base, were investigated to determine the feasibility of obtaining a supply of ground water. Five test holes were drilled and three of these were completed with 6-inch casings. Ground water in the eastern part...
Measurement of the reaeration coefficients of the North Fork Licking River at Utica, Ohio by radioactive tracers
Janet Hren
1983, Water-Resources Investigations Report 83-4192
Reaeration coefficients of the North Fork Licking River at Utica, Ohio were measured by the radioactive-tracer method. The tests were conducted on a 2.1-mile reach on September 23 and October 7, 1981, during low-flow conditions. Krypton-85 gas and tritium were the radioopactive tracers, which were used in conjunction with rhodamine-WT...

Altitude of the top of the Matawan Group-Magothy Formation, Suffolk County, Long Island, New York
Richard K. Krulikas, E. J. Koszalka, Thomas P. Doriski
1983, Open-File Report 83-137
The Magothy aquifer, with its irregular surface and deeply eroded buried valleys, has become the major source of fresh water in most of Suffolk Country. With the availability of recent data from deep wells and test holes, refinement of the surface-altitude contours has been possible and resulted in substantial revision...
Hydrogeologic and water-quality characteristics of the Prairie du Chien-Jordan aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf, D. G. Adolphson
1983, Water-Resources Investigations Report 83-4045
Quality of water in the Prairie du Chien-Jordan aquifer is generally good, except for some localized contamination, Coal-tar derivatives that contaminate the aquifer in St. Louis Park, a western suburb in the Twin Cities Metropolitan Area, pose the most serious threat to water quality. High hardness and iron concentration limit...
Land application of wastewater and its effect on ground-water quality in the Livermore-Amador Valley, Alameda County, California
M. A. Sylvester
1983, Water-Resources Investigations Report 82-4100
Ground-water quality, ground-water level, and rainfall data collected during the 1975 water year through the 1980 water year were analyzed to determine the effects of land application of effluent from wastewater treatment plants on ground-water quality in the Livermore-Amador Valley. Annual rainfall varied markedly during the study: 1976 and 1977...
Petrology and comparative thermal and mechanical histories of clasts in breccia 62236
Gordon L. Nord Jr., M.-V. Wandless
1983, Journal of Geophysical Research Solid Earth (88) A645-A657
Lunar breccia 62236 contains large lithic fragments of troctolite, norite, and anorthosite. The mafic phases, olivine, inverted pigeonite, and augite, fill interstitial areas between larger plagioclases and appear to be cumulate phases with extensive adcumulus growth. Pyroxene compositional homogeneity indicates that cation exchange during cooling was limited to an area...

Crustal structure beneath the southern Appalachians: Nonuniqueness of gravity modeling
Deborah R. Hutchinson, John A. Grow, Kim D. Klitgord
1983, Geology (11) 611-615
Gravity models computed for a profile across the long-wavelength paired negative-positive Bouguer anomalies of the southern Appalachian Mountains show that the large negative anomaly can be explained by a crustal root zone, whereas the steep gradient and positive anomaly east of the root may be explained equally well by three...
