Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems
Jerry P. Eaton
1975, Open-File Report 75-663
The purpose of these experiments is to lay the groundwork for the implementation of subtractive compensation of the USGS seismic network tape playbacks utilizing the Develco model 6203 discriminators at a x1 playback speed. Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was...
Sandstone geometry, porosity and permeability distribution, and fluid migration in eolian system reservoirs
Robert Lupe, Thomas S. Ahlbrandt
1975, Open-File Report 75-357
Upper Paleozoic to Mesozoic eolian blanket sandstones of the Colorado Plateau and the Rocky Mountains of Colorado and southern Wyoming are texturally complex. As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and...
Some limnological aspects of 20 selected lakes in Eagan and Apple Valley, Minnesota
M.R. Have
1975, Open-File Report 75-528
Selected physical, chemical, and biological parameters were determined to assess the quality of 20 lakes in the cities of Eagan and Apple Valley, Minn. All the lakes are eutrophic except Holland and Fish Lakes, which are mesotrophic. Some lakes (including Fish Lake) have storm sewer inlets but are not discernibly...
Environmental tritium in the Edwards Aquifer, central Texas 1963-71
Frederick Joseph Pearson, Paul L. Rettman, T.A. Wyerman
1975, Open-File Report 74-362
Tritium concentrations of samples from 50 wells and springs in the Edwards aquifer in the San Antonio area of Texas have been analysed. Tritium now in the aquifer is partly natural cosmic ray produced tritium, but most is tritium produced by atmospheric thermonuclear tests in the 1950's and early 1960's....
Stochastic analysis of particle movement over a dune bed
Baum K. Lee, Harvey E. Jobson
1975, Open-File Report 75-358
Stochastic models are available that can be used to predict the transport and dispersion of bed-material sediment particles in an alluvial channel. These models are based on the proposition that the movement of a single bed-material sediment particle consists of a series of steps of random length separated by rest...
