1980, Sixth Annual Pecora Symposium and Exposition 51-51
Magset was launched on October 30, 1979. More than a decade of examining existing data, devising appropriate models of the global magnetic field, and extending methods for interpreting long-wavelength magnetic anomalies preceded this launch Magnetic data collected by satellite can be interrupted by using a method of analysis that quantitively...
Digital mapping of limonitic rocks by using Landsat MSS radio data
Melvin H. Podwysocki, Donald B. Segal, Shirley Simpson
Anthony R. Barringer, editor(s)
1980, Sixth Annual Pecora Symposium and Exposition 49-51
Color-ratio composite images of Landsat MSS (multi-spectral scanner) bands have been used by other workers to map the distribution of limonitic rocks in semi-arid and arid areas as possible indicators of hydrothermal alteration (Rowan et al, 1974). The images are particularly useful for broad overviews, but detailed analysis at...

1980, Sixth Annual Pecora Symposium and Exposition 40-42
Experiments with an imaging airborne Fraunhofer line discriminator (FLD) are being conducted to establish the feasibility of delineating the areal extent of luminescent materials on the earth's surface from aircraft and spacecraft. All luminescence measurements are related to a standard set of conditions with rhodamine wt dye used as...

1980, Sixth Annual Pecora Symposium and Exposition 71-73
Airborne spectroradiometer surveys over several forest-covered sulfide bodies indicate that mineralization has affected the overlying vegetation; anomalous spectral reflectivity properties can be detected in the vegetation using appropriate remote-sensing interments and data-reduction techniques. Mineralization induces subtle changes in the shape of the chlorophyll a and b absorption spectrum between...
Use of solid-state 13C NMR in structural studies of humic acids and humin from Holocene sediments
Patrick G. Hatcher, D.L. VanderHart, W.L. Earl
1980, Organic Geochemistry (2) 87-92
13C NMR spectra of solid humic substances in Holocene sediments have been obtained using cross polarization with magic-angle sample spinning techniques. The results demonstrate that this technique holds great promise for structural characterizations of complex macromolecular substances such as humin and humic acids. Quantifiable distinctions can be made between structural...
The natural food habits of grizzly bears in Yellowstone National Park, 1973-74
Stephen Patrick Mealey
1980, Book chapter, Bears - Their biology and management
The natural food habits of grizzly bears (Ursus arctos horribilis Ord) in Yellowstone National Park were investigated in 1973-74 to identify the grizzly's energy sources and trophic level(s), nutrient use, and distribution. Food consumption was determined by scat analysis and field observations. Food quality and digestibility were estimated by chemical...
Effective and bankfull discharges of streams in the Yampa River basin, Colorado and Wyoming
E.D. Andrews
1980, Journal of Hydrology (46) 311-330
The effective discharge is defined as the increment of discharge that transports the largest fraction of the annual sediment load over a period of years. Increments of the average annual total sediment load transported by various discharges were calculated by the flow-duration, sediment-transport-curve method for 15 gaging stations in the...
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,...
High duck nesting success in a predator-reduced environment
Harold F. Duebbert, John T. Lokemoen
1980, Journal of Wildlife Management (44) 428-437
Duck nesting and production were studied during 1969-74 on a 51-ha field of undisturbed grass-legume cover and a surrounding 8.13-km2 area in north-central South Dakota. The principal mammalian predators of ducks were reduced within a 259-km2 zone from May 1969 through August 1971. Dabbling duck nest densities, hatching success, and...
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...

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...

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...

E. Allen Merewether, George E. Claypool
1980, American Association of Petroleum Geologists Bulletin (64) 488-500
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...

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...
