Estimation of background loadings and concentrations of phosphorus for lakes in the Puget Sound region, Washington
Robert J. Gilliom
1980, Open-File Report 80-328
For lakes in watersheds that include developed land, evaluation of eutrophication is facilitated by knowledge of changes in the lakes ' phosphorus concentration since development. A method is described for estimating background phosphorus concentration in lakes of the Puget Sound lowland, Washington. Using a mass-balance ' Vollenweider-type ' model, phosphorus...

Mekometer measurements in the Imperial Valley, California, 1980
Ronald G. Mason, C.N. Crook, Perry Rowley Wood
1980, Open-File Report 81-1141
During a six-week period in the Spring of 1980, approximately seven months after the October 15, 1979 earthquake, parts of the Imperial Valley mekometer network (Fig. 1) were re-measured for comparison with measurements made during the twelve months preceding the earthquake and the six weeks following it. The purpose was...
Digital-model projection of saturated thickness and recoverable water in the Ogallala Aquifer, Texas County, Oklahoma
Robert B. Morton
1980, Open-File Report 79-565
A digital model was used to provide a quantitative description of the Ogallala aquifer in Texas County, Oklahoma, and to predict saturated thickness and water in storage from the aquifer at specified future times. The Ogallala aquifer, which consists of unconsolidated sand, gravel, and clay, is the principal source of...
Histograms and correlation table for selected elements in samples of the ash of black spruce needles from the Tanacross Quadrangle, Alaska
Gary C. Curtin, G.W. Day, R. B. Tripp
1980, Open-File Report 80-655
These histograms and correlation table show the distribution and abundance of, and correlations between, the populations of 21 elements in the ash of black spruce (Picea Mariana B.S.P.) needles collected throughout most of the Tanacross 1:250,000-scale quadrangle. The samples were collected during reconnaissance geochemical studies as part of the U.S....

Biological premonitors of earthquakes: A validation study
Leon Spelly Otis, W.H. Kautz
1980, Open-File Report 80-1152
For the greatest ultimate usefulness to society, the two most important facets of earthquake prediction are (1) a fundamental scientific understanding of the earthquake-triggering process and (2) the identification of reliable and measurable premonitors. A possible approach to both of these problem areas, and one that has received almost no...
