Elevation changes
A. S. Jayko, G.A. Marshall, G. A. Carver
1992, Earthquakes & Volcanoes (USGS) (23) 139-143
The magnitude 7.1 mainshock on April 25, 992, caused substantial changes in the elevation of the Earth's surface in the Cape Mendocino region. Precise measurements of such elevation changes aid in long-term emergency planning and are needed for engineering design and the maintenance of roads, bridges, and waterways. Such measurements...

Sampling vadose-zone water for a volatile organic compound at Picatinny Arsenal, New Jersey
James A. Smith, H. Jean Cho, Peter R. Jaffe, Cecilia L. MacLeod, Susan A. Koehnlein
1992, Journal of Environmental Quality (21) 264-271
A new method of collecting samples of unsaturated-zone water for quantitative analysis for a volatile organic compound, trichloroethene (TCE), was compared to three other, previously described sampling methodologies in the laboratory and in the field. In the laboratory, prepared water samples containing TCE in a known concentration (20 µg/L) were...
Debris flow rheology: Experimental analysis of fine-grained slurries
Jon J. Major, Thomas C. Pierson
1992, Water Resources Research (28) 841-857
The rheology of slurries consisting of ≤2-mm sediment from a natural debris flow deposit was measured using a wide-gap concentric-cylinder viscometer. The influence of sediment concentration and size and distribution of grains on the bulk rheological behavior of the slurries was evaluated at concentrations ranging from 0.44 to 0.66. The...

Prevalence of Renibacterium salmoninarum among downstream-migrating salmonids in the Columbia River
J. E. Sanders, J.J Long, C.K. Arakawa, J. L. Bartholomew, J. S. Rohovec
1992, Journal of Aquatic Animal Health (4) 72-75
Bacterial kidney disease (BKD) is an important contributor to mortality of salmonids in hatcheries in the Columbia River basin. However, the impact of BKD on the survival of downstream migrants is difficult to determine because there is little information on the disease-related mortality among these fish. In this study, the...

Lake acidity and mercury content of fish in Darwin National Reserve, Russia
Terry A. Haines, V. Komov, C. H. Jagoe
1992, Environmental Pollution (78) 107-112
Darwin National Reserve is a protected natural area on the north-west shore of the Rybinsk Reservoir, 350 km north of Moscow. In June 1989, six lakes in the Reserve and the reservoir were surveyed to assess lake acidity and the mercury content of perch, Perca fluviatilis. Five were seepage lakes...
Breeding chronology of mottled ducks in a Texas coastal marsh
J. Barry Grand
1992, Journal of Field Ornithology (63) 195-202
The relationship between breeding chronology of Mottled Ducks (Anas fulvigula fulvigula) and wetland conditions at San Bernard National Wildlife Refuge was examined over a 3-yr period. Median nest initiation dates varied by as much as 68 d among years. Initiation occurred earlier in 1985 and 1987 versus 1986 (P <...

Changes in Alaskan soft-bottom prey communities along a gradient in sea otter predation
R.G. Kvitek, J.S. Oliver, A.R. DeGange, B.S. Anderson
1992, Ecology (73) 413-428
Sea Otter (Enhydra lutris), well documented as "keystone" predators in rocky marine communities, were found to exert a strong influence on infaunal prey communities in soft-sediment habitats. Direct and indirect effects of sea otter predation on subtidal soft-bottom prey communities were evaluated along a temporal gradient of sea otter occupancy...

Land cover mapping of the Upper Kuskokwim Resource Management Area, Alaska, using Landsat and a digital data base approach
Carl Markon
1992, Canadian Journal of Remote Sensing (18) 62-71
Digital land cover and terrain data for the Upper Kuskokwim Resource Management Area in south-central Alaska were produced by the U.S. Geological Survey for the U.S. Bureau of Land Management. These and other environmental data were incorporated into a digital data base to assist in the production of a land...
Tensiometers: Theory, construction, and use
D.I. Stannard
1992, Geotechnical Testing Journal (15) 48-58
Standard tensiometers are used to measure matric potential as low as −870 cm of water in the unsaturated zone by creating a saturated hydraulic link between the soil water and a pressure sensor. The direction and, in some cases, quantity of water flux can be determined using multiple installations.A variety...
Roosting behavior of premigratory Dunlins (Calidris alpina)
Colleen M. Handel, Robert E. Gill Jr.
1992, The Auk (109) 57-72
We studied roosting behavior of Dunlins (Calidris alpina) during late summer along the coast of the Yukon-Kuskokwim Delta, Alaska, in relation to tidal cycle, time of day, time of season, and occurrence of predators. Within Angyoyaravak Bay, peak populations of 70,000-100,000 Dunlins occur each year. The major diurnal roost sites...

Arthur D. Bradfield
1992, Water-Resources Investigations Report 92-4018
The hydrology of Cave Springs, the second largest spring in East Tennessee was investigated from July 1987 to September 1989. Wells near the spring supply about 5 million gallons per day of potable water to people in Hamilton County near Chattanooga. Discharge from the spring averaged about 13.5 cubic feet...
Reference samples for use in analytical geochemistry: their availability, preparation, and appropriate use
J. S. Kane
1992, Journal of Geochemical Exploration (44) 37-63
A large number of certified and other reference samples are available for use in analytical geochemistry. Certified materials are preferred, but of much more limited availability than other reference samples for most geochemical applications. The availability of rock, sediment, soil, water,...
