1988, Conference Paper
Elevated concentrations of selenium in water, bottom sediment, and biota were noted during a reconnaissance investigation of the Kendrick Reclamation Project in central Wyoming. Dissolved-selenium concentrations in 11 of 24 samples of surface or ground water exceeded the national drinking-water standard of 10 micrograms per liter. Bottom-sediment samples contained concentrations...
Tectonic history of the Syria Planum province of Mars
K. L. Tanaka, P. A. Davis
1988, Journal of Geophysical Research Solid Earth (93) 14893-14917
We attribute most of the development of extensive fractures in the Tharsis region to discrete tectonic provinces within the region, rather than to Tharsis as a single entity. One of these provinces is in Syria Planum. Faults and collapse structures in the Syria Planum tectonic province on Mars are grouped...
Simulation of three lahars in the Mount St Helens area, Washington using a one-dimensional, unsteady-state streamflow model
Antonius Laenen, R. P. Hansen
1988, Water-Resources Investigations Report 88-4004
A one-dimensional, unsteady-state, open-channel model was used to analytically reproduce three lahar events. Factors contributing to the success of the modeling were: (1) the lahars were confined to a channel, (2) channel roughness was defined by field information, and (3) the volume of the flow remained relatively unchanged for the...

Causes of two slope-failure types in continental-shelf sediment, northeastern Gulf of Alaska
William C. Schwab, Homa J. Lee
1988, Journal of Sedimentary Research (58) 1-11
Slumps and sediment-gravity flows have been identified in Holocene glaciomarine sediment on declivities less than 1.3 degrees on the Gulf of Alaska continental shelf. Geologic and geotechnical investigation suggest that the processes responsible for these slope failures are earthquake and storm-wave loading, coupled with cyclic degradation of the sediment-shear strength....

1988, Uranium (4) 281-305
Anomalously uraniferous waters occur in a small (4.2 km2) drainage in the west-central Carson Range, Nevada, on the eastern side of Lake Tahoe. The waters transport uranium from local U-rich soils and bedrock to organic-rich valley-fill sediments where it is concentrated, but weakly bound. The dissolved U and the U...
A bioassay for production capacity assessment
J. W. Meade
1988, Aquacultural Engineering (7) 139-146
Given sufficient oxygen, fish production can be limited by a multiplicity of factors. Accurate determination of production capacity requires something other than an estimate of the biomass at which ambient un-ionized ammonia will reach a recommended, non-site-specific, maximum safe concentration. A chronic (1- to 2-month) bioassay can be used to...
