High throughput Landsat imagery film recorder
David E. Ulmer
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...
Early acquisition of characteristic magnetization in red beds of the Moenkopi Formation (Triassic), Gray Mountain, Arizona
Michael E. Purucker, Donald P. Elston, Eugene Merle Shoemaker
1980, Journal of Geophysical Research B: Solid Earth (85) 997-1012
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...
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...
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...
Organic composition of some Upper Cretaceous shale, Powder River Basin, Wyoming
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...
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...
The role of remote sensing in the Department of Interior
Allen H. Watkins
1980, Conference Paper, Western Regional Remote Sensing Conference proceedings
Since its creation in 1849, USDI has faced the challenging mission of being custodian of the Nation's natural resources. USDI is directly responsible for management of 30 % of the United State's land area, including administration of more than 600 million acres of Federal land and 300 million acres of...
Effects of recreational river traffic on nest defense by longear sunfish
Gordon Mueller
1980, Transactions of the American Fisheries Society (109) 248-251
An underwater camera system was designed to record the behavior of male nest-guarding longear sunfish (Lepomis megalotus) during periods of boating activity. Boats traveling at slow speeds near nests usually drove males from their nests, increasing the likelihood of egg predation. Boats moving at higher speeds or further from nests...
Some comments on Anderson and Pospahala's correction of bias in line transect sampling
David R. Anderson, K.P. Burnham, B.R. Chain
1980, Biometrical Journal (22) 513-524
ANDERSON and POSPAHALA (1970) investigated the estimation of wildlife population size using the belt or line transect sampling method and devised a correction for bias, thus leading to an estimator with interesting characteristics. This work was given a uniform mathematical framework in BURNHAM and ANDERSON (1976). In this paper we...
An assessment of Landsat data acquisition history on identification and area estimation of corn and soybeans
M.A. Hixon, M. E. Bauer, Donna K. Scholz
1980, Report, LARS technical reports
During the past decade, numerous studies have demonstrated the potential of satellite remote sensing for providing accurate and timely crop area information. This study assessed the impact of Landsat data acquisition history on classification and area estimation accuracy of corn and soybeans.Multitemporally registered Landsat MSS data from four acquisitions during...
Ecology of a Maryland population of black rat snakes (Elaphe o. obsoleta)
Lucille F. Stickel, William H. Stickel, F. C. Schmid
1980, American Midland Naturalist (103) 1-14
Behavior, growth and age of black rat snakes under natural conditions were investigated by mark-recapture methods at the Patuxent Wildlife Research Center for 22 years (1942-1963), with limited observations for 13 more years (1964-1976). Over the 35-year period, 330 snakes were recorded a total of 704 times. Individual home ranges...

L.A. Braconnier, P.J. Wiepking
1980, Report
The EROS Data Center is a part of the Earth Resources Observation Systems (EROS) Office of the Department of the Interior and is managed by the U.S. Geological Survey. It is the national clearinghouse for the processing and dissemination of spacecraft- and aircraft-acquired images and photographs and electronic data on...
Topographic maps: Tools for planning
George A. Kaufman
1980, Report
Topographic maps are a detailed record of a land area, giving geographic positions and elevations for both natural and man-made features. They show the shape of the land the mountains, valleys, and plains by means of brown contour lines (lines of equal elevation above sea level). In steep mountainous areas,...
