Hydrologic data for wells, springs, and streams in Boulder County, Colorado
Dennis C. Hall, Elaine L. Boyd, Doug Cain
1979, Open-File Report 79-979
Hydrologic data collected in 1975-77 as part of a comprehensive water-resources investigation of Boulder County, Colo., by the U.S. Geological Survey in cooperation with the Boulder County Health Department and the Colorado Geological Survey are presented in this report. The data, in tabular and graphic form, consist of water-quality analyses...
Potential geologic hazards and constraints for blocks in proposed North Atlantic OCS oil and gas lease sale 42
Robert W. Hall
1979, Open-File Report 79-1285
Analysis of side-scan sonar, 3.5 kHz subbottom profiler, sparker, and fathometer data (approximately 9,900 km) from 206 blocks originally selected for proposed Outer Continental Shelf Lease Sale 42 disclosed potential hazards to oil and gas exploration and development operations. These potential hazards are a shallow gas deposit in one proposed...
A total intensity magnetic anomaly map of the Red Sea and its interpretation
Stuart A. Hall
1979, Open-File Report 80-131
All available total intensity magnetic field data have been used to prepare a total intensity magnetic anomaly map of the Red Sea at a scale of 1:2,000,000. These include airborne surveys at various elevations and numerous sea surveys. The data have been digitised at approximately one kilometre intervals and the...
Mid- and North Atlantic multichannel seismic reflection profiles, 7, 8 A, B, and C, 12 E, F, G, H, I, and J, and 13 A, B, C, D, E, F, G, and H
Water Resources Division, U.S. Geological Survey
1979, Open-File Report 78-685
Available are four multichannel profiles collected by Digicon Geophysical Corporation in 1975 using a 48-channel streamer (3600 m long), and a 27.9 cubic liter airgun array. They were processed in Denver on the Phoenix "I" by William C. Petterson. The processing includes demultiplexing and resampling, geometry and common-depth-point, definition, velocity...
K-Ar age of alunite alteration at Red Mountain, Lake City area, western San Juan Mountains, Colorado
Harald H. Mehnert, John F. Slack, Gerald T. Cebula
1979, Open-File Report 79-1642
The San Juan Mountains of southwestern Colorado are famous for rich vein deposits of base and precious metals and for patterns of conspicuous hydrothermal alteration. Areas of acid-sulfate alteration, characterized by extensive base leaching of volcanic rocks or hypabyssal plutons, are of current interest because of their local association with...
Quaternary stratigraphic sections with radiocarbon dates, Chandalar Quadrangle, Alaska
Thomas D. Hamilton
1979, Open-File Report 79-751
Surficial geologic mapping of the Chandalar quadrangle was carried out during 1975 and 1976 as part of the Arctic Environmental Program of the U.S. Geological Survey. Ten organic samples were collected at that time for radiocarbon dating. Six samples have been dated by Stephen W. Robinson at the U.S. Geological...
Seismicity of the Tihamat-Asir region, Kingdom of Saudi Arabia
Habib M. Merghelani
1979, Open-File Report 79-1191
Knowledge of the seismicity of the west coast of Saudi Arabia is vitally important to the Kingdom. The eastern margin of the Red Sea, which includes all of the west coast of Saudi Arabia, is possibly cut by transform faults that may be capable of producing earthquakes large enough to...
Notes on the acquisition of high resolution seismic reflection profiles, side-scanning sonar records, and sediment samples from lower Cook Inlet and Kodiak Shelf, R/V Sea Sounder Cruise S8-78-WG, August 1978
Monty A. Hampton, Arnold H. Bouma
1979, Open-File Report 79-1311
The third U.S. Geological Survey geo-environmental cruise in lower Cook Inlet and on the Kodiak shelf and adjacent continental slope, Gulf of Alaska, was conducted aboard the R/V SEA SOUNDER from 2 August to 22 August, 1978 (Fig. 1, 2, and 3). The objectives of the cruise were to study...
Seismic, magnetic, and geotechnical properties of a landslide and clinker deposits, Powder River basin, Wyoming and Montana
C.H. Miller
1979, Open-File Report 79-952
Exploitation of vast coal and other resources in the Powder River Basin has caused recent, rapid increases in population and in commercial and residential development and has prompted land utilization studies. Two aspects of land utilization were studied for this report: (1) the seismic and geotechnical properties of a landslide...
Hydrologic reconnaissance of western Arctic Alaska, 1976 and 1977
Joseph M. Childers, Donald R. Kernodle, Robert M. Loeffler
1979, Open-File Report 79-699
A reconnaissance of the water resources of the western Arctic was conducted during April 1976 and August 1977. Data were collected at 9 springs, 9 lakes and 22 stream sites.Using slope-conveyance methods based on field evidence, estimates of bankfull and maximum evident flood-peak discharges were made for 20 selected streams....
Field verification of reconstructed dam-break flood, Laurel Run, Pennsylvania
Cheng-lung Chen, Jeffrey T. Armbruster
1979, Open-File Report 79-1483
A one-dimensional dam-break flood routing model is verified by using observed data on the flash flood resulting from the failure of Laurel Run Reservoir Dam near Johnstown, Pennsylvania. The model has been developed on the basis of an explicit scheme of the characteristics method with specified time intervals. The model...
