The new federal OCS regulations in the light of Santa Barbara
Russell G. Wayland
1969, Conference Paper, SPE California regional meeting
When the first Outer Continental Shelf leases were issued in 1954, the oil industry was operating near shore in shallow waters. Although regional OCS Orders issued under the regulations have been kept reasonably up to date with advancing technology, the Secretary's regulations had not undergone a complete review by the...
Great Salt Lake, Utah: Chemical and physical variations of the brine, 1963-1966
D. C. Hahl, A.H. Handy
1969, Utah Geological and Mineralogical Survey Water-Resources Bulletin 12
Great Salt Lake is a shallow, closed-basin lake in northern Utah. Its surface area and concentration of dissolved solids vary in response to both annual and long-term climatic changes. The lake gains water mainly as streamflow from mountains to the east and loses water through evaporation. In 1965, at a...
Mud Lake, Florida: Its algae and alkaline brown water
W. H. Bradley, M. E. Beard
1969, Limnology and Oceanography (14) 889-897
Mud Lake (Marion County, Florida), in the Ocala National Forest, is elliptical, has an area of ca. 180 ha, and a mean depth of less than 50 cm. The water contains about 200 ppm dissolved solids, ranges from brown to nearly colorless (15 to 100 Pt units),...
Effect of rainfall variability on streamflow simulation
D.R. Dawdy, James M. Bergmann
1969, Water Resources Research (5) 958-966
Three recording rain gages in a 9.7‐square‐mile basin in southern California were used with a deterministic rainfall‐runoff model to simulate flood hydrographs and peaks and to assess the effects of data errors on simulation results. Bias in the estimation of effective basin rainfall seemed to result in curve fitting parameter...
International geophysics: Symposium on the hydrology of deltas
Ted Arnow
1969, Eos Science News (50) 556-556
A Symposium on the Hydrology of Deltas was held in Bucharest, Romania, on May 6–9; it was followed by a field trip to the delta of the Danube River on May 10–14. The Symposium was organized by Unesco, with the collaboration of the Romanian Government and the support of the...
Progress on a gravity map of Alaska
David F. Barnes
1969, Eos Science News (50) 550-552
The U.S. Geological Survey began gravity surveys in Alaska ten years ago with local surveys in the Copper River and Tanana Basins. Shortly before the 1963 AGU gravity symposium [Barnes, 1965], the emphasis shifted from local surveys to the preparation of a reconnaissance gravity map of the whole state with...
The U.S. Geological Survey's gravity program in the Rocky Mountain and Basin Range areas
M. Dean Kleinkopf, Donald L. Peterson
1969, Eos, Transactions, American Geophysical Union (50) 529-531
Most of the gravity surveys of the U.S. Geological Survey have been support programs in connection with regional geologic structural studies, ground-water investigations, and heavy-metals exploration. Many of the studies were undertaken in conjunction with geological mapping and mineral...
Waterfowl production in relation to grazing
L.M. Kirsch
1969, Journal of Wildlife Management (33) 821-828
A 4-year production study of upland nesting waterfowl on the Missouri Coteau area of North Dakota showed that pair numbers, nesting densities and nest success were generally reduced by grazing. It is suggested that cover removal such as regular grazing and mowing be discontinued on areas managed primarily for waterfowl...
Flow of a disperse emulsion of crude oil in water in porous media
John C. Cartmill, Parke A. Dickey
1969, Conference Paper, Fall meeting of the Society of Petroleum Engineers of AIME
It has been suggested that oil migrates through reservoir sands in the form of a fine, disperse emulsion of oil in water, and that oil accumulations occur where the stream enters finer-grained rock such as silt or shale. In order to investigate the possible mechanisms, stable emulsions of oil in...
Thermal additions and epifaunal organisms at Chalk Point, Maryland
Jon W. Nauman, Robert L. Cory
1969, Chesapeake Science (10) 218-226
Two sets of test panels, one in the intake and the other in the effluent canal of a steam-generating station, were submerged at monthly intervals in 1967. The panels were analyzed for epifaunal species composition, abundance, seasonal attachment, and total biomass production. The average surface-water temperature rose 6.3 C above...
A system for planning and scheduling water resources studies and construction projects
E. F. LeRoux, D. G. Jorgenson
1969, Groundwater (7) 16-18
A simplification of the two most commonly used methods of network planning and scheduling is ideally suited to the planning and evaluation of both water resources studies and construction projects. The project planning diagrams illustrate the system for scheduling of project activities and the relation of...
An application of surface geophysical techniques to the study of watershed hydrology
Ronald R. Shields, William E. Sopper
1969, Journal of the American Water Resources Association (JAWRA) (5) 37-49
The applicability of geophysical methods to experimental watershed research is demonstrated by a study of a 106-acre forested watershed in central Pennsylvania. Data from a shallow seismic refraction study and an electrical resistivity study of the watershed were used to determine the depth of soils, their volumes, depth to bedrock,...
Chemical composition of the hydrothermal fluids responsible for the lead-zinc deposits at Providencia, Zacatecas, Mexico
Robert O. Rye, Joseph Haffty
1969, Economic Geology (64) 629-643
The chemical composition of 22 samples of primary fluid inclusions in quartz, calcite, and sphalerite from Providencia, Mexico, has been determined. Samples were prepared, crushed, and leached as described by Roedder et al. (1963). Cation analyses of leachates were made by atomic absorption spectroscopy, and the anions were analyzed by...
The ground-water situation in Ohio
Stanley E. Norris
1969, Groundwater (7) 25-33
Present ground-water use in Ohio, approximately 650mgd (million gallons per day) amounts to about 5 percent of the water that enters the ground-water reservoirs. The largest ground-water supplies are developed where natural concentrations of water occur, chiefly in the watercourse aquifers, which consist of sand and gravel of glacial origin...
Tertiary climatic change in the marginal northeastern Pacific Ocean
W.O. Addicott
1969, Science (165) 583-586
Analysis of distributional patterns of shallow-water molluscan faunas of the middle latitudes of the marginal northeastern Pacific Ocean discloses a sharp reversal during the Miocene of the progressive climatic deterioration. A low point in the Tertiary cooling trend during the Oligocene was followed by climatic warming that culminated during the...
Cretaceous, Tertiary, and early Pleistocene rocks from the continental margin in the Bering Sea
David M. Hopkins, David W. Scholl, Warren O. Addicott, Richard L. Pierce, Patsy Beckstead Smith, Jack A. Wolfe, David Gershanovich, Boris Kotenev, Kenneth E. Lohman, Jere H. Lipps, John D. Obradovich
1969, Geological Society of America Bulletin (80) 1471-1480
Rocks dredged from the continental margin in eastern Bering Sea in and near the Pribilof Canyon indicate that the acoustic basement represents the upper surface of thoroughly lithified turbidite beds of graywacke and siltstone of Late Cretaceous age. The stratified sequence covering the acoustic basement is gently deformed and includes...

Errors in using modern stream-load data to estimate natural rates of denudation
Robert H. Meade
1969, Geological Society of America Bulletin (80) 1265-1274
The practice of calculating natural rates of denudation from routinely collected data on the loads of suspended and dissolved matter in modern rivers is subject to several significant errors. The sources of these errors are demonstrated by examples from the Atlantic drainage of the United States, where their total effect...
Measuring underground-explosion effects on water levels in surrounding aquifers
M. S. Garber, Leonard E. Wollitz
1969, Groundwater (7) 3-7
Underground detonations may produce observable effects in surrounding aquifers and wells. The nature and the duration of the effect at any observation point seem to depend on several factors such as the amount of energy released by the detonation, the geologic environment, the position of the buried explosive device in...
Hydrology of carbonate rock terranes — A review: With special reference to the United States
V. T. Stringfield, H. E. LeGrand
1969, Journal of Hydrology (8) 349-376
Limestone and other carbonate rocks are characterized by many unusual features and extreme conditions, either involving the hydrologic system within them or wrought by hydrologic conditions on them or through them. Perhaps there could be little agreement as to what is typical or average for the many features of carbonate...
