Dynamics of turbidity plumes in Lake Ontario
Edward J. Pluhowski
1975, Open-File Report 75-249
Large-turbidity features along the 275-kilometre long south shore of Lake Ontario were analyzed using LANDSAT-1 images. The ESIAC system developed by the Stanford Research Institute, was used to obtain enlargements and false-color renditions of turbidity plumes. After projection on a video screen, individual turbidity features were analyzed, mapped, and photographed.The...
Geothermal significance of eastward increase in age of upper Cenozoic rhyolitic domes in southeastern Oregon

Rhyolitic domes, flows, and ash-flow tuffs of Miocene to Holocene age form an important part of the thick sequence of Cenozoic volcanic rocks that cover southeastern Oregon east of the Cascade Range. Rhyolitic domes 11-17 m.y. old are widespread, particularly in the easternmost part of the state and in adjacent...
Digital-model study of ground-water hydrology, Columbia Basin Irrigation Project Area, Washington
H.H. Tanaka, A. J. Hansen Jr., J.A. Skrivan
1974, Water Supply Bulletin 40
Since 1952 water diverted from the Columbia River at Grand Coulee Dam has been used to irrigate parts of the Columbia Basin Irrigation Project area in eastern Washington, and as a result ground-water levels generally have risen in the area. The rapid increases in ground-water inflow, outflow, and storage from...

1974, American Association of Petroleum Geologists Bulletin (58) 1179-1190
To assess the area’s hydrocarbon potential, regional geologic and geophysical studies are being conducted by the U.S. Geological Survey to determine the structural framework of the United States Atlantic outer continental shelf (AOCS) north of Cape Hatteras. Preliminary interpretations of geophysical data suggest that the buried ridge under the eastern...
Geology and mineral deposits of Churchill County, Nevada
Ronald Willden, Robert C. Speed
1974, NBMG Bulletin 83
Churchill County, in west-central Nevada, is an area of varied topography and geology that has had a rather small total mineral production. The western part of the county is dominated by the broad low valley of the Carson Sink, which is underlain by deposits of Lake Lahontan. The bordering mountain...
Progress report on the North American Breeding Bird Survey

During Late 1970 and early 1971, 229 woodcock (Philohela minor) were collected from 23 Eastern and Midwestern States. Analyses for chlorinated hydrocarbons and mercury in these migratory birds showed generally low levels which are not considered dangerous to human consumers. In this survey, Louisiana woodcock had lower...

Kevin M. Scott, Rhea P. Williams
1974, Water-Resources Investigations Report 73-47
Major-storm and long-term erosion rates in mountain watersheds of the western Transverse Ranges of Ventura County are estimated to range from low values that will not require the construction of catchments or channel-stabilization structures to values as high as those recorded anywhere for comparable bedrock erodibilities.A major reason for this...

Hariharaiyer Mahadeva Iyer
1974, Open-File Report 74-96
The U. S. Geological Survey made seismic noise measurements in the East Mesa area of Imperial Valley, California, to find out if a noise anomaly was associated with the Mesa thermal anomaly.
