Comparison of a few recording current meters in San Francisco Bay, CA
R. T. Cheng
1978, Conference Paper, Proceedings, Conference on Current Measurements
A team of research scientists in the U.S. Geological Survey uses San Francisco Bay, California, as an outdoor laboratory to study complicated interactions of physical, chemical, and biological processes which take place in an estuarine environment. A current meter comparison study was conceived because of the need to select a...

Conceptual models in exploration geochemistry-The Basin and Range Province of the Western United States and Northern Mexico
T.G. Lovering, J. H. McCarthy Jr.
1978, Journal of Geochemical Exploration (9) 113-276
This summary of geochemical exploration in the Basin and Range Province is another in the series of reviews of geochemical-exploration applications covering a large region; this series began in 1975 with a summary for the Canadian Cordillera and Canadian Shield, and was followed in 1976 by a similar summary for...
Time-dependence of sea-ice concentration and multiyear ice fraction in the Arctic Basin
P. Gloersen, H.J. Zwally, A.T.C. Chang, D.K. Hall, W. J. Campbell, R.O. Ramseier
1978, Boundary-Layer Meteorology (13) 339-359
The time variation of the sea-ice concentration and multiyear ice fraction within the pack ice in the Arctic Basin is examined, using microwave images of sea ice recently acquired by the Nimbus-5 spacecraft and the NASA CV-990 airborne laboratory. The images used for these studies were constructed from data acquired...
A pollution history of Chesapeake Bay
E.D. Goldberg, V. Hodge, M. Koide, J. Griffin, E. Gamble, O.P. Bricker, G. Matisoff, G.R. Holdren Jr., R. Braun
1978, Geochimica et Cosmochimica Acta (42) 1413-1425
Present day anthropogenic fluxes of some heavy metals to central Chesapeake Bay appear to be intermediate to those of the southern California coastal region and those of Narragansett Bay. The natural fluxes, however, are in general higher. On the bases of Pb-210 and Pu-239 + 240 geochronologies and of the...
Uranium-isotope variations in groundwaters of the Floridan aquifer and Boulder Zone of south Florida
J.B. Cowart, M. I. Kaufman, J.K. Osmond
1978, Journal of Hydrology (36) 161-172
Water samples from four wells from the main Floridan aquifer (300-400 m below mean sea level) in southeast Florida exhibit 234U 233U activity ratios that are significantly lower than the secular equilibrium value of 1.00. Such anomalous values have been observed previously only in waters from sedimentary aquifers in the...

Range charts and no-space graphs
Lucy E. Edwards
1978, Computers & Geosciences (4) 247-255
No-space graphs present one solution to the familiar problem: given data on the occurrence of fossil taxa in separate, well-sampled sections, determine a range chart; that is, a reasonable working hypothesis of the total range in the area in question of each taxon studied. The solution presented here treats only...
The marine geology of the eastern Santa Barbara Channel, with particular emphasis on the ground water basins offshore from the Oxnard Plain, Southern California
H. Gary Greene, Stephen C. Wolf, Ken G. Blom
1978, Open-File Report 78-305
Marine geophysical investigations provide new data concerning the stratigraphy, tectonic and sedimentary history, and the ground water geology of the southeastern Santa Barbara Channel region. The offshore stratigraphy identified in seismic reflection profiles includes a succession of Neogene to Quaternary strata. The middle Miocene Conejo volcanics form an acoustical basement...
Radioactive disequilibrium in altered mid-oceanic basalts
M.P. Bacon
1978, Earth and Planetary Science Letters (39) 250-254
A young (<1 m.y.) tholeiitic basalt dredged from the Mid-Atlantic Ridge displays a234U excess and a230Th deficiency that have resulted from the addition of seawater uranium during weathering at seafloor temperatures. Two older samples, though they acquired substantial amounts of uranium...
Preliminary analytical results for a new U.S. Geological Survey Devonian Ohio Shale Standard SDO-1
Joel S. Leventhal, J.G. Crock, W. Mountjoy, J.A. Thomas, V.E. Shale, Paul H. Briggs, J.S. Wahlberg, M.J. Malcolm
1978, Open-File Report 78-447
Using several analytical techniques, results of analysis of U. S. Geological Survey new standard SDO-1 are given for selected elements. The Devonian black shale shows an organic carbon content of approximately 10.3 percent, a sulfur content of approximately 5.6 percent, and a uranium content of approximately 56 ppm. Some elements...
Predicting earthquakes along the major plate tectonic boundaries in the Pacific
H. Spall
1978, Earthquake Information Bulletin (USGS) (10) 20-25
In an article in the last issue of the Earthquake Information Bulletin ("Earthquakes and Plate Tectonics," by Henry Spall), we saw how 90 percent of the world's earthquakes occur at the margins of the Earth's major crustal plates. however, when we look at the distribution of earthquakes in detail, we...

Dr. Gilbert White is Director of the Institute of Behavioral Science at the University of Colorado, Boulder, where he is responsible for natural Hazards Research and Applications Information Center supported by the National Science Foundation. He served in the Executive Office of the president in 1941-42, on the Federal Flood...
Radon emanation on the San Andreas Fault
C. Y. King
1978, Earthquake Information Bulletin (USGS) (10) 136-138
Radon is a radioactive gas with a half-life of 3.8 days. (Half-life is the time required for the substance to lose half of its radioactivity by decay.) It is itself produced by the decay of uranium. Radon is constantly emanated from the Earth into the atmosphere. Many cases are known...
Amplitude of foreshocks as a possible seismic precursor to earthquakes
A.G. Lindh
1978, Earthquake Information Bulletin (USGS) (10) 162-164
In recent years, we have made significant progress in being able to recognize the long-range pattern of events that precede large earthquakes. For example, in a recent issue of the Earthquake Information Bulletin, we saw how the pioneering work of S.A. Fedotov of the U.S.S.R in the Kamchatka-Kurile Islands region has...
Empirical model of Skeletonema costatum photosynthetic rate, with applications in the San Francisco Bay estuary
James E. Cloern
1978, Advances in Water Resources (1) 267-274
An empirical model of Skeletonema costatum photosynthetic rate is developed and fit to measurements of photosynthesis selected from the literature. Because the model acknowledges existence of: 1) a light-temperature interaction (by allowing optimum irradiance to vary with temperature), 2) light inhibition, 3) temperature inhibition, and 4) a salinity effect, it accurately estimates...
Water-level monitoring in the area of the Palmdale Uplift, Southern California
D.L. Lamar, P.M. Merifield
1978, Earthquake Information Bulletin (USGS) (10) 144-147
Abnormal behavior of water levels in wells has been observed prior to a number of earthquakes. For instance, water-level minima have been noted in the Cienega Winery well before earthquakes on the San Andreas fault. Abnormal water-level fluctuations were used in conjunctions with other precursors to predict the February 4,...

J.E. Colwell, D.S. Gilmer, E.A. Work Jr., D. Rebel
1978, Report
This report is a discussion of the feasibility of using Landsat data to generate information of value for effective management of migratory waterfowl. Effective management of waterfowl includes regulating waterfowl populations through hunting regulations and habitat management. This report examines the ability to analyze annual production by monitoring the number...
