Ray J. Hoffman
1979, Open-File Report 79-679
A study was made to evaluate the effects that treated sewage has on some characteristics of water quality in a reach of the Merced River near Yosemite National Park. Streamflow and water-quality data were collected from July through October 1975 and from July through November 1977 at five stations on...
Preliminary report on an exploratory drill hole: New Madrid test well-1-X in Southeast Missouri
Anthony J. Crone, D. P. Russ
1979, Open-File Report 79-1216
As part of the U.S. Geological Survey's investigation of earthquake hazards in the upper Mississippi embayment, a test well (NMTW-l-X) was drilled in the "bootheel" of Missouri, 21 km south-southwest of the town of New Madrid. The primary purpose of the well was to obtain in situ stress measurements from...

Gazetteer of coastal and offshore features of the Bering Sea and Aleutian Arc
Marybeth Gerin
1979, Open-File Report 79-1219
This gazetteer presents the names of seafloor and coastal features of the Bering Sea and Aleutian Arc. It is the second of three gazetteers that cover the offshore and coastal features of Alaska. Alaska was divided into three major regions - the Gulf of Alaska (Gerin and Molnia, 1978), the...
Elevations and discharges produced by a simulated flood wave on the lower Sabine River, Louisiana and Texas, caused by a theoretical dam failure
Braxtel L. Neely, Gloria J. Stiltner
1979, Open-File Report 79-678
The Toledo Bend Reservoir is located on the lower Sabine River between Louisiana and Texas. The objective of this study was to calculate the flood wave that would result from the theoretical failure of 25 percent of Toledo Bend Dam and route the wave downstream to Orange, Tex. Computations assumed...

Late diagenetic indicators of buried oil and gas: II, Direct detection experiment at Cement and Garza oil fields, Oklahoma and Texas, using enhanced LANDSAT I and II images
Terrence J. Donovan, Patricia A. Termain, Mitchell E. Henry
1979, Open-File Report 79-243
The Cement oil field, Oklahoma, was a test site for an experiment designed to evaluate LANDSAT's capability to detect an alteration zone in surface rocks caused by hydrocarbon microseepage. Loss of iron and impregnation of sandstone by carbonate cements and replacement of gypsum by calcite are the major alteration phenomena...
Geometric considerations for an automated mapping satellite system (Mapsat)
Alden P. Colvocoresses
1979, Open-File Report 79-914
The geometry of the frame photograph whether taken from an aircraft or a satellite is well known and documented. Transforming photographs into maps is a relatively slow and expensive process which for many critical steps defies automation. A satellite offers the unique advantages of greater stability and uniform velocity over...
