Mid-Atlantic multichannel seismic-reflection profiles 14, 15, 16, and 17
John Stevens Schlee
1980, Open-File Report 80-624
The U. S. Geological Survey (USGS) is making available four multi­channel profiles collected by Teledyne Exploration in 1977 by means of a 48-channel streamer (3600 m long) and four airguns (2160 in). Profiles 15 and 16 were processed by.Teledyne Exploration and profiles 14 and 17 were processed on the Phoenix...
Single-channel seismic-reflection profiles from Massachusetts coastal waters and the western part of Georges Bank
Diane M. Eskenasy
1980, Open-File Report 80-509
The U.S. Geological Survey collected approximately 1,200 km each of airgun and minisparker single-channel seismic-reflection profiles during the R/V FAY cruise 023 in September 1976. The purpose of the 6-day cruise was to study the shallow sedimentary structure south and east of southern Massachusetts and to obtain magnetic and gravity...
Simulated water-level declines near Marienthal, west-central Kansas
Lloyd E. Dunlap
1980, Water-Resources Investigations Report 80-39
Intensive study in an area of 12-square miles near Marienthal, Kansas, has shown a decrease of 30 to 50 percent in saturated thickness of the Ogallala Formation since the development of irrigation. Projections from a digital model indicated the additional water-level declines that might occur from 1978 to 1989 if...
Side-scan sonograph data from eastern Rhode Island Sound and Vineyard Sound, Massachusetts
Charles J. O’Hara
1980, Open-File Report 80-283
Two hundred twenty-four kilometers of closely spaced side-scan sono­graph data have been collected from eastern Rhode Island Sound and Vineyard Sound, Mass., by the U.S. Geological Survey in cooperation with the New England Division of the U.S. Army Corps of Engineers. These data were obtained during the August 1976 cruise...
The U.S. Geological Survey in Alaska 1980 programs
Katherine M. Reed, editor(s)
1980, Circular 823-A
This circular describes the 1980 programs of the U.S. Geological Survey in Alaska. A brief description of the Alaskan operations of each major division of the Survey is followed by project descriptions arranged by geographic regions in which the work takes place. The mission of the Geological Survey is to...
Seismicity map of the State of West Virginia
B.G. Reagor, C. W. Stover, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1226
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
Reconnaissance snow survey of the National Petroleum Reserve in Alaska, April-May 1979
William J. Glude, Charles E. Sloan
1980, Water-Resources Investigations Report 80-49
Moderately low snowfall and an early and abrupt spring thaw resulted in removal of most of the snow cover from the National Petroleum Reserve in Alaska (NPRA) before the snow survey of April 30 through May 2, 1979. Logistical problems and lack of snow permitted sampling at only seven sites....
Chemical, physical, and radiological quality of selected public water supplies in Florida : January-May 1979
Bernard J. Franks, G. A. Irwin
1980, Water-Resources Investigations Report 80-13
Verde Valley--an area of complex geology where the crust of the North American plate changes from unstable to stable--is in central Arizona in the transition zone between the Basin and Range and the Colorado Plateaus tectonic provinces. Volcanism and tectonism have been progressing northeastward along the transition zone for about...
In-situ measurements of seismic velocity at 27 locations in the Los Angeles, California region
James F. Gibbs, Thomas E. Fumal, Edward F. Roth
1980, Open-File Report 80-378
Studies conducted in the San Francisco Bay Region (Gibbs, Fumal and Borcherdt, 1980) have shown that average shear-wave velocity can be readily tied to quantitative estimates of ground motion such as ground amplification and earthquake intensity. Furthermore, when certain physical properties of the geologic materials such as texture, hardness and...
The Boulder Creek Batholith, Front Range, Colorado
Dolores J. Gable
1980, Professional Paper 1101
The Boulder Creek batholith is the best known of several large Precambrian batholiths of similar rock composition that crop out across central Colorado. The rocks in the batholith belong to the calc-alkaline series and range in composition from granodiorite through quartz diorite (tonalite) to gneissic aplite. Two rock types dominate':...
Summary of the river-quality assessment of the upper Chattahoochee River basin, Georgia
R.N. Cherry, R.E. Faye, J. K. Stamer, R.L. Kleckner
1980, Circular 811
The river-quality assessment of the Upper Chattahoochee River Basin included studies of (1) the impact of heat loads on river quality, (2) sediment transport and deposition, (3) magnitude and nature of point and nonpoint discharges, and (4) phytoplankton growth in the river and reservoirs. The combined thermal effects of flow...
Waste-assimilation capacity of the Arkansas River in Pueblo County, Colorado, as it relates to water-quality guidelines and stream classification
Doug Cain, Duaina Baldridge, Patrick Edelmann
1980, Water-Resources Investigations Report 80-82
The waste-assimilation capacity of a 42-mile reach of the Arkansas River in Pueblo County, Colo., was evaluated using a one-dimensional steady-state water-quality model. The model was calibrated and verified using hydraulic and water-quality data collected in 1976 and 1979. The water-quality con-stituents modeled were 5-day carbonaceous biochemical oxygen demand, total...
