Prehistoric Alaska: The land
Frederic H. Wilson, Florence R. Weber
Penny Rennick, editor(s)
1994, Alaska Geographic (21) 6-23
Many Alaskans know the dynamic nature of Alaska’s landscape firsthand. The 1964 earthquake, the 1989 eruption of Mount Redoubt volcano, the frequent earthquakes in the Aleutians and the ever-shifting meanders of the Yukon and Kuskokwim rivers remind them of constant changes to the land. These changes are part of the...
Remote sensing and airborne geophysics in the assessment of natural aggregate resources
D. H. Knepper Jr., W. H. Langer, S.H. Miller
1994, Open-File Report 94-158
Natural aggregate made from crushed stone and deposits of sand and gravel is a vital element of the construction industry in the United States. Although natural aggregate is a high volume/low value commodity that is relatively abundant, new sources of aggregate are becoming increasingly difficult to find and develop because of rigid industry...
Demographic and life history characteristics influence the cytonuclear composition of mosquitofish populations
Kim T. Scribner, John C. Avise
A. Beaumont, editor(s)
1994, Book chapter, Genetics and evolution of aquatic organisms
Experimental laboratory crosses and population experiments reveal significant differences in individual life-history traits and population demography between two related species of mosquitofish, Gambusia affinis and G. holbrooki. With respect to life-history traits, progeny from G. holbrooki exhibit larger size at birth and earlier age at sexual maturity than do progeny...
South Cascade Glacier, Washington; hydrologic and meteorological data, 1957-67
M.E. Sullivan
1994, Open-File Report 94-77
Historic hydrologic and meteorological data are compiled for South Cascade Glacier, Washington, USA, a site selected by the U.S. Geological Survey for long-term study of the response of a glacier to climate change and its effect on water resources. The data consist of stream discharge and meteorological data, including precipitation,...
Green Crab Alert
A. M. Kuris, K. D. Lafferty
1994, Crab Newsletter (1) 4-5
No abstract available at this time...
Estimates of monthly streamflow characteristics and dominant-discharge hydrographs for selected sites in the lower Missouri and Little Missouri River basins in Montana
Charles Parrett, D.R. Johnson
1994, Water-Resources Investigations Report 94-4098
Various streamflow characteristics were estimated for water-reservation purposes for 17 sites in the lower Missouri River Basin and four sites in the Little Missouri River Basin in Montana. The characteristics were mean monthly and annual streamflow and monthly mean streamflow that is exceeded 90, 80, 50, and 20 percent of...
Bacterial kidney disease
R.J. Pascho, D.G. Elliott
J. Thosen, editor(s)
1994, Book chapter, Procedures for the detection and identification of certain fish pathogens
No abstract available...
Importance of spatial pattern in estimating predation on juvenile salmonids in the Columbia River
James H. Petersen
1994, Transactions of the American Fisheries Society (123) 924-930
The impact of piscivores in aquatic systems is often estimated by assuming that predation rate and predator density can be characterized as means throughout large, homogeneous areas. Predation losses of juvenile Pacific salmonids Oncorhynchus spp. migrating through Columbia River reservoirs were previously estimated with the assumption that each reservoir consisted...
Geologic map of the MTM -85080 quadrangle (revised), Planum Australe region of Mars
Kenneth E. Herkenhoff, Bruce C. Murray
1994, IMAP 2391
Published geologic maps of south polar region of Mars have been based on either Mariner 9 (Condit Soderblom, 1978; Scott and Carr, 1978) or Viking Orbiter (Tanaka and Scott, 1987) images. The mapped extent of the southern layered deposits differs in many places on these maps and on our...
