Basin development along the Late Mesozoic and Cainozoic California Margin: A plate tectonic margin of subduction, oblique subduction and transform tectonics
David G. Howell, James K. Crouch, H. G. Greene, David S. McCulloch, J. G. Vedder
1980, Book chapter, Sedimentation in Oblique-Slip Mobile Zones
Along the Californian margin of the North American plate, the configuration and structural stability of late Mesozoic and Cainozoic basins are related to plate kinematics. Three tectonic regimes are recorded; orthogonal high-angle subduction, oblique low-angle subduction, and transform slip. During the first, regionally extensive forearc basins...
Geology and hydrology for environmental planning in Washtenaw County, Michigan
William B. Fleck
1980, Report
Washteaw County is underlain by glacial deposits that range in thickness from about 50 feet to about 450 feet. Underlying the glacial deposits are sedimentary rocks of Mississippian and Devonian age. The youngest of these rocks are the sandstones of the Marshall Formation in the western part of the county; ...
Sediment waves on the Monterey fan levee: a preliminary physical interpretation.
William R. Normark, Gordon R. Hess, D.A.V. Stow, A.J. Bowen
1980, Marine Geology (37) 1-18
Sediment waves on the deep ocean floor occur mostly on the lower continental rise on slopes of 1° or less. Previous studies show that their amplitude and wavelength vary greatly, but little is known about their shape in plan. A detailed survey of a 30-km2 area of abyssal-depth sediment waves associated...
Transfer of crude oil from contaminated water to bird eggs
P.H. Albers
1980, Environmental Research (22) 307-314
Paris of breeding mallard ducks were exposed to oiled water for 2 days during the first week of incubation. Hatching success of ducks exposed to 100 ml of Prudhoe Bay crude oil per square meter of water surface was significantly less than that of controls. Hatching success of ducks exposed...
Late Cenozoic volcanism, geochronology, and structure of the Coso Range, Inyo County, California
Wendell A. Duffield, Charles R. Bacon, G. Brent Dalrymple
1980, Journal of Geophysical Research B: Solid Earth (85) 2381-2404
The Coso Range lies at the west edge of the Great Basin, adjacent to the southern part of the Sierra Nevada. A basement complex of pre‐Cenozoic plutonic and metamorphic rocks is partly buried by ∼35 km3 of late Cenozoic volcanic rocks that were erupted during two periods, as defined by K‐Ar...
Sediment transport in Norton Sound, Alaska
D.E. Drake, D.A. Cacchione, R.D. Muench, C.H. Nelson
1980, Marine Geology (36) 97-126
The Yukon River, the largest single source of Bering Sea sediment, delivers > 95% of its sediment load at the southwest comer of Norton Sound during the ice-free months of late May through October. During this period, surface winds in the northern Bering Sea area are generally light from the...
Variability of currents and sediment transport on continental shelves: Optical and current meter studies of the bottom boundary layer
H. A. Karl, D.E. Drake, D.A. Cacchione
1980, Proceedings of SPIE (208) 143-150
The Continental Margin Sediment Dynamics program of the U.S. Geological Survey has been using a variety of optical instruments to monitor water turbidity as part of our studies of sediment transport. Although we suspect that optical devices will eventually be supplanted by more direct measures of suspended sediments, results of...
Liquefaction potential of the Yukon Prodelta, Bering Sea
E.C. Clukey, D.A. Cacchione, C.H. Nelson
1980, Conference Paper, 12th annual offshore technology conference; Proceedings
The Yukon prodelta is exposed to large storm waves propagating northward from the southern Bering Sea. Shallow water depths of the prodelta enhance the transfer of energy from the surface waves to the bottom. As the bottom deposits are cyclically loaded by large storm waves, potential decrease in their resistance...
Current-controlled, abyssal microtopography and sedimentation in Mozambique Basin, southwest Indian Ocean
V. Kolla, S. Eittreim, L. Sullivan, J.A. Kostecki, L.H. Burckle
1980, Marine Geology (34) 171-206
The Antarctic Bottom Water (AABW) activity and the variations in the abundance and grain size of the terrigenous sediments, derived from Africa and Madagascar land masses, are reflected in different types of microtopography in the Mozambique Basin. In southerly areas, where the sediment supply is much less, the bottom-current activity...
High frequency radar measurements of tidal currents flowing through San Pablo Strait, San Francisco Bay
Joseph W. Maresca Jr., Robin R. Padden, Ralph T. Cheng, Erwin Seibel
1980, Limnology and Oceanography (25) 929-935
High frequency (HF) radar measurements of the surface current averaged over the upper 0.5 m in San Pablo Strait were compared with current meter measurements of the subsurface current made at 9.4 m below mean lower low water (MLLW) over two 12.4-h tidal cycles. After averaging the radar and current...
Mesozoic and Cenozoic structural trends under southern Bering Sea shelf
Michael S. Marlow, Alan K. Cooper
1980, AAPG Bulletin (64) 2139-2155
Mesozoic rocks exposed near the tip of the Alaska Peninsula form an antiformal structure that flanks the southern side of Bristol Bay basin and that can be traced with geophysical data about 700 km offshore to the vicinity of the Pribilof Islands. Upper Jurassic sandstone and Upper Cretaceous mudstone dredged...
Water-resources investigations, Collier County, Florida
Howard Klein
1980, Open-File Report 80-1207
Early water-resources investigations in Collier County, Fla., were related to saltwater intrusion in Naples. With the advent of canal drainage and land reclamation farther inland, investigations were directed at effects of canals on water resources and the environment. High on the list of investigative needs are: (1) areal and vertical...
Ground water resources of Lee County
Donivan L. Gordon
1980, Report
Approximately 8.0 percent of the water used in Lee County comes from underground sources. It is estimated that the use of ground water in the county currently approaches 2.8 billion gallons per year. For comparison, this amount would provide each resident with 172 gallons of water a day during a...
Water resources planning under the Fish and Wildlife Coordination Act
Karl F. Stutzman
1980, FWS/OBS 80/44
This paper briefly discusses the more significant provisions of the Fish and Wildlife Coordination Act (1958). It covers pertinent aspects of legislative history, the development and current status (April 1980) of certain policies relevant to administering the Act, and other matters. It is directed primarily to practicing fish and wildlife...
