Maps & minds : mapping through the ages
Water Resources Division, U.S. Geological Survey
1984, Report
Throughout time, maps have expressed our understanding of our world. Human affairs have been influenced strongly by the quality of maps available to us at the major turning points in our history. "Maps & Minds" traces the ebb and flow of a few central ideas in the mainstream of mapping....
Late Miocene (Santa Margarita Sandstone) shallow marine clastics
R. Lawrence Phillips
1984, Report
The Santa Margarita Sandstone of late middle and early late Miocene age is located in the western Santa Cruz Mountains of central California. It represents a marine, tide-dominated, transgressive deposit which, during the early stage of the marine transgression formed a seaway connection between the Pacific Ocean and the interior...
Bibliography of water-resources reports for Arizona through 1982
Natalie D. White, Randall L. Fields
1984, Report
This bibliography is a listing of reports concerning the water resources of Arizona obtained by computer search of three bibliographic files: Water Resources Scientific Information Center (WRSIC); National Technical Information Service (NTIS); and GEOREF, from the American Geological Institute. The three files gave listings of several hundred reports, not all...
Significant unconformities and the hiatuses represented by them in the Paleogene of the Atlantic and Gulf Coastal Province
Joseph E. Hazel Jr., Lucy E. Edwards, Laurel M. Bybell
1984, Book chapter, Interregional unconformities and hydrocarbon accumulation
A biostratigraphic, chronostratigraphic, and magnetostratigraphic model has been calibrated to produce a new time scale for the Paleogene. The model gives the biostratigraphic position and duration represented by significant unconformities in three areas of the Atlantic and Gulf Coastal Province: 1) western and central Alabama; 2) South Carolina; and 3)...
Surficial geology
Charles B. Hunt
1984, Report
Surficial materials are those at or near the Earth's surface. They constitute, by far, the largest and most used part of the ground around us. Areas not covered by surficial deposits--bare bedrock--form probably less than 5 percent of our land surface.Most surficial deposits are composed of poorly consolidated clay, silt,...
Rippled scour depressions on the inner continental shelf off central California
David A. Cacchione, David E. Drake, William D. Grant, George B. Tate
1984, Journal of Sedimentary Petrology (54) 1280-1291
Side-scan sonar records taken during the recent Coastal Ocean Dynamics Experiment (CODE) show elongate, shore-normal rippled depressions of low relief on the inner continental shelf off central California between Bodega Bay and Point Arena. These features extend up to 2 km from the...
Refuge management analyses: research needs for Muscatatuck National Wildlife Refuge
J. E. Roelle, G.T. Auble, D. B. Hamilton
1984, Report
Muscatatuck National Wildlife Refuge, located in southeastern Indiana, was established by the Migratory Bird Conservation Commission in 1966. Land use planning for the Refuge formally began in 1971, and development of facilities designed in that planning effort is now nearing completion. As these facilities become operational, Refuge personnel will be...
Compilation of hydrologic data for the Edwards Aquifer, San Antonio area, Texas, 1981, with 1934-81 summary
R.D. Reeves, R.W. Maclay, G. B. Ozuna
1984, Edwards Underground Water District Bulletin 41
The average annual ground-water recharge to the Edwards aquifer in the San Antonio area, Texas, from 1934 through 1981, was 612,400 acre-feet. The recharge in 1981 was 1,448,400 acre-feet, which is the third highest annual recharge since 1934. A maximum annual recharge of 1,711,200 acre-feet occurred in 1958, and a...
Pleistocene glaciation of volcano Ajusco, central Mexico, and comparison with the standard Mexican glacial sequence
Sidney White, S. Valastro
1984, Quaternary Research (21) 21-35
Three Pleistocene glaciations and two Holocene Neoglacial advances occurred on volcano Ajusco in central Mexico. Lateral moraines of the oldest glaciation, the Marqués, above 3250 m are made of light-gray indurated till and are extensively modified by erosion. Below 3200 m the till is dark red, decomposed, and buried beneath...
Snow Mountain Wilderness Study Area, California
Robert D. Brown Jr., Francis E. Federspiel
1984, Book chapter
The Snow Mountain Wilderness study area, located about 120 mi north of San Francisco and on the divide between the Sacramento and Eel Rivers, contains some of the highest terrain in the Coast Ranges. Its mineral-resource potential was evaluated by interpreting data from geologic field studies, from an aeromagnetic survey,...
Red fox predation on breeding ducks in midcontinent North America
Alan B. Sargeant, Stephen H. Allen, Robert T. Eberhardt
1984, Wildlife Monograph 89
Red fox (Vulpes vulpes) predation on nesting ducks was assessed by examining 1,857 adult duck remains found at 1,432 fox rearing dens from 1968 to 1973. Dabbling ducks were much more vulnerable to foxes than diving ducks. Dabbling ducks (1,798) found at dens consisted of 27% blue-winged teals (Anas discors),...
Effects of weather on breeding ducks in North Dakota
M.C. Hammond, Douglas H. Johnson
1984, Fish and Wildlife Technical Report 1
The present report quantifies relations between weather and several aspects of the breeding biology of four duck species: mallard (Anas platyrhynchos), gadwall (A. strepera), blue-winged teal (A. discors), and redhead (Aythya americana). Data were obtained from two locations in North Dakota,--the J. Clark Salyer National Wildlife Refuge, intermittently during 1936-68,...
