Sedimentology and geochemistry of surface sediments, outer continental shelf, southern Bering Sea
J.V. Gardner, W.E. Dean, T.L. Vallier
1980, Marine Geology (35) 299-329
Present-day sediment dynamics, combined with lowerings of sea level during the Pleistocene, have created a mixture of sediments on the outer continental shelf of the southern Bering Sea that was derived from the Alaskan Mainland, the Aleutian Islands, and the Pribilof ridge. Concentrations of finer-grained, higher-organic sediments in the region...
Ecological survey of the night monkey, Aotus trivirgatus, in Formosa Province, Argentina
G. B. Rathbun, M. Gache
1980, Primates (21) 211-219
Transect surveys were carried out in northern Argentina during October and November 1977 in order to determine the distribution and abundance ofAotus trivirgatus. The monkeys were seen in pairs with one to two recent young and occurred at a density of approximately six family groups/km2.Aotus was only found in relatively moist,...

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...

A necropsy procedure for sampling disease in wild birds
Charles van Riper III, Sandra G. van Riper
1980, Condor (82) 85-98
This paper presents a necropsy procedure for examining small wild birds, designed to be used by investigators without experience in avian pathology. It gives instructions on how to conduct a postmortem examination, lists the needed equipment, tells what parts of a bird to save when a disorder in encountered, and...
High throughput Landsat imagery film recorder

1980, Conference Paper, Proceedings Volume 0200, Laser Recording and Information Handling
The Earth Resources Observation Systems (EROS) Data Center is responsible for processing, archiving, reproducing, and distributing satellite and aircraft remotely-sensed Earth imagery data in both film and digital format. Landsat Multispectral Scanner (MSS) and Return Beam Vidicon (RBV) sensor data alone represents a daily recording requirement of 23 billion pixels...

Four discrete magnetizations associated with events occurring during deposition, early diagenesis, recent weathering, and cloud to ground lightning have been identified in rocks of the Moenkopi Formation at Gray Mountain, Arizona. A paleomagnetic study of more than 800 samples tied closely to the physical stratigraphy of the...

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...
Organic composition of some Upper Cretaceous shale, Powder River Basin, Wyoming

The lower Upper Cretaceous strata in northeastern Wyoming, which have yielded major quantities of oil and gas, were sampled at boreholes in Converse, Johnson, and Weston Counties. Cores of noncalcareous shale of largely nearshore-marine origin were obtained from the Frontier Formation and the overlying Cody Shale at depths of 3,780.6...

Plastic deformation of MgO(A12O2)1·1 spinel at 0·28TM preliminary results
Stephen H. Kirby, P. Veyssiere
1980, Philosophical Magazine A: Physics of Condensed Matter, Structure, Defects and Mechanical Properties (41) 129-136
Prism-shaped single crystals of MgO(Al2O3)n spinel (n < 1.1) have been compressed to significant plastic strain at a temperature of 400°C (∼0·28 TM) in controlled experiments under a superimposed hydrostatic pressure of 1·4 GPa. Compression of crystals approximately parallel to <001>, <111> and <011> resulted in simple yield behaviour at axial...
Paleomagnetic evidence for oroclinal bending of the southern Antarctic Peninsula
Karl S. Kellogg
1980, GSA Bulletin (91) 414-420
Two classes of fracture zones are distinguished on the basis of their orientations with respect to a spreading axis and length of associated ridge-ridge transform offset. (1) Minor fracture zones associated with transform faults of short offset (<30 km; minitransforms); the minor fracture zones may exhibit an asymmetric V-shaped configuration...
Tectonic tilt rates derived from lake-level measurements, Salton Sea, California
M.E. Wilson, S. H. Wood
1980, Science (207) 183-186
Tectonic tilt at the Salton Sea was calculated by differencing lake-level measurements from two points on the sea. During the past 26 years, tilting was down toward the southeast. By 1970 differential vertical movement amounted to 110 millimeters between two gages situated 38 kilometers apart on the southwest shore. A...

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...
