Audio-magnetotelluric methods in reconnaissance geothermal exploration
Donald B. Hoover, Carl L. Long
1975, Open-File Report 75-362
About three years ago, at the initiation of a major effort by the U.S. Geological Survey into studies of geothermal systems, a decision was made to evaluate the audio-magnetotelluric, AMT, technique for this application. At that time we had had no real experience with the method nor any equipment. Some...
Geology of the Jabel Ishmas Quadrangle, Kingdom of Saudi Arabia
Louis Gonzales, Vincent J. Flanigan
1975, Open-File Report 75-181
The Jabal Ishmas quadrangle (20/43A) is about 100 km northeast of Qal'at Bishah in the southern part of the Arabian Shield. Most of the terrane in the quadrangle slopes gently westward across broad expanses of pediment, from prominent mountainous north-south ridges in the east to the alluvial and eolian sand-covered...
Flow characteristics of the Lower Wisconsin River
J. H. Green
1975, Open-File Report 75-582
The flow of water throughout the year and the stream gradient are necessary considerations in evaluating the recreational potential of the lower Wisconsin River. This flow is regulated in part by the dam at Prairie du Sac and influenced considerably by the 47 storage reservoirs and power dams above Lake...
WATSTORE: National Water Data Storage and Retrieval System of the U. S. Geological Survey; user's guide
Norman E. Hutchison
1975, Open-File Report 75-426
The U.S. Geological Survey investigates the occurrence , quantity, quality, distribution, and movement of the surface and underground water resources of the Nation. The investigations, which are conducted by the Water Resources Division, of the Survey include: systematic collection, analysis, and interpretation of water data; investigation of in and agricultural...
High-gain, long-period seismograph station installation report, Matsushiro, Japan
Charles R. Hutt
1975, Open-File Report 75-100
A High-Gain, Long-Period Seismograph System was installed at Matsushiro, Japan, during November and December 1972. The system consists of two horizontal and one vertical seismometer with natural periods of 30 seconds. Each seismometer contains two velocity transducers and one displacement transducer....
High-gain, long-period seismograph station installation report, Kipapa, Hawaii
Charles R. Hutt
1975, Open-File Report 75-369
A High-Gain, Long-Period Seismograph System, developed by the Lamont-Doherty Geological Observatory, was installed at the Kipapa site of the Honolulu Observatory near Ewa Beach, Oahu, Hawaii in March 1972. Magnifications of 55,000 for the vertical component and 40,000 for the horizontal components were obtained. Velocity data are recorded both photographically...
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...
Origin and age of postglacial deposits and assessment of potential hazards from future eruptions of Mount Baker, Washington
Jack H. Hyde, Dwight Raymond Crandell
1975, Open-File Report 75-286
Eruptions and other geologic processes at Mount Baker during the last 10,000 years have repeatedly affected adjacent areas, and especially the valleys that head at the volcano. Most mudflows from the volcano were caused by massive avalanches of volcanic rock that had been partly altered to clay by steam and...
A water-quality assessment of the Burnham Creek Watershed, Polk County, Minnesota
M.R. Have
1975, Open-File Report 75-647
A water-quality assessment of the Burnham Creek watershed, Polk County, Minn., was made in May 1975. Surface waters were calcium magnesium bicarbonate types with 0.11 mg/liter or less of nitrite plus nitrate nitrogen and 0.10 mg/liter or less of total phosphorous. Fecal coliform bacteria concentrations were between 3 and 720...
