Slug tests for determining hydraulic conductivity of natural geologic deposits
This paper reviews four methods for analyzing slug test data to determine hydraulic conductivity and examines the effects of slug size on slug test results. Data from more than 100 slug tests, including tests for low permeability (glacial tills and fractured rock) deposits, coarse-grained (sand) deposits, and simulated tests were analyzed. Analysis of the data showed that all four analytical metho

Strong-motion data processing
Processing of strong-motion earthquake accelerograms is now carried out routinely on a world-wide basis. Two international workshops have given participants the opportunity to assess their capabilities. Data from the larger instrumentation networks are disseminated widely. The US Geological Survey's strong-motion network consists largely of film recorders, due to their long reliable life and the r

The status of sea ducks in the North Pacific Rim: Toward their conservation and management
Sea ducks (tribe Mergini after Johnsgard 1960) are the most northerly distributed ducks, and species diversity is greatest in the North Pacific. They exploit a diversity of inshore and offshore marine habitats during the non-breeding season, and their use of habitat during breeding varies from coastal through freshwater wetlands of the tundra and taiga (Figure 1, Appendix 1). Non-breeding cohorts

Ultraviolet-B radiation and the immune response of rainbow trout: Chapter 18
As part of a larger study on global climate change and ozone depletion we are investigating the effects of ultraviolet-B (UVB) radiation on fishes. We conducted a number of experiments to explore the possible effects of UVB radiation on the immune response of juvenile rainbow trout Oncorhynchus mykiss. In one study, the fish developed sunburn and fungal infection on the dorsal skin after exposure

Volume-controlled hydrologic property measurements in triaxial systems
New capabilities for hydrologic property measurements in triaxial systems include: (1) volume-controlled and simultaneous measurements of hydraulic conductivity and one-dimensional consolidation (or specific storage) of a saturated test specimen; and (2) volume-controlled measurements of hydraulic conductivity, matric potential, and the variation of these properties with the moisture content of an

Width adjustment: relative dominance in unstable alluvial streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment were investigated: vertical processes and fluvial action, bed-material particle, cohesive strength of bank material, and riparian vegetation.

Production and decomposition of Spartina patens in a degrading coastal marsh
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m2 yr-1 during 1991 and 1,696 g m-1 yr-1 during 1992. The relative decomposition rate of S. patens stems was -0.001152 g g-1 d-1 which may be restated as a half life of 395 days. Both production and decomposition rates for this area arelow relative
