Digital terrain tapes: user guide
Water Resources Division, U.S. Geological Survey
1980, Report
DMATC's digital terrain tapes are a by-product of the agency's efforts to streamline the production of raised-relief maps. In the early 1960's DMATC developed the Digital Graphics Recorder (DGR) system that introduced new digitizing techniques and processing methods into the field of three-dimensional mapping. The DGR system consisted of an...

Evaluation of a cavity-riddled zone of the shallow aquifer near Riviera Beach, Palm Beach County, Florida
John North Fischer Jr.
1980, Water-Resources Investigations Report 80-60
The shallow aquifer near Riviera Beach, Palm Beach County, Fla., contains a cavity-riddled zone extending north and south about 5 miles inland from the Atlantic Ocean. The zone lies at approximately 60 feet below land surface and varies from 15 to 50 feet in thickness. It is approximately 3 miles...
Paleolimnology of two lakes in the Klutlan Glacier region, Yukon Territory, Canada
J.P. Bradbury, M.C. Whiteside
1980, Quaternary Research (14) 149-168
Lakes developed on progressively younger end moraines of the Klutlan Glacier were initially assumed to have originated shortly after moraine emplacement and to have persisted to the present. Limnological differences between lakes on old vs young moraines were thought to result from limnological maturation within the lakes and ponds themselves...
The origin and distribution of subbottom sediments in southern Lake Champlain
R. P. Freeman-Lynde, D. R. Hutchinson, D. W. Folger, B.H. Wiley, M.J. Hewett
1980, Quaternary Research (14) 224-239
Three units, correlatable with recent Lake Champlain, late-glacial marine Champlain Sea, and proglacial Lake Vermont sediments, have been identified from about 200 km of high-resolution seismic reflection profiles and eight piston cores collected in southern Lake Champlain. Lake Vermont deposits are nonfossiliferous and range from thin to absent nearshore and...
Biostratigraphic correlation of Pleistocene marine deposits and sea levels, Atlantic coastal plain of the southeastern United States
T. M. Cronin
1980, Quaternary Research (13) 213-229
Marine ostracodes from 50 localities were studied to determine the age and elevation of Pleistocene sea levels in the Atlantic coastal plain from Maryland to northern Florida. Using ostracode taxon and concurrent ranges, published planktic biostratigraphic, paleomagnetic, and radiometric data, ostracode assemblage zones representing early (1.8-1.0 my), middle (0.7-0.4 my),...
Remote sensing data of SP Mountain and SP Lava flow in north-central Arizona

1980, Remote Sensing of Environment (9) 149-170
Multifrequency airborne radar image data of SP Mountain [Official name of feature (U.S. Geological Survey, 1970)] and SP flow (and vicinity) in north-central Arizona were obtained in diverse viewing directions and direct and cross-polarization, then compared with surface and aerial photography, LANDSAT multispectral scanner data, airborne thermal infrared imagery, surface...
Local magnetic field measurements and fault creep observations on the San Andreas fault
M.J.S. Johnston, B.E. Smith, Robert O. Burford
1980, Tectonophysics (64) 47-57
Simultaneous creep and magnetic field records have been obtained for more than 60 episodic creep events since early 1974, no clear magnetic transients or offsets, as suggested by Breiner and Kovach (1968), are observed at or up to several days before the occurrence times of these events. Although some patterns...
Folding and faulting of strain-hardening sedimentary rocks
Arvid M. Johnson
1980, Tectonophysics (62) 251-278
The question of whether single- or multi-layers of sedimentary rocks will fault or fold when subjected to layer-parallel shortening is investigated by means of the theory of elastic-plastic, strain-hardening materials, which should closely describe the properties of sedimentary rocks at high levels in the Earth's crust. The most attractive feature...
Single and superimposed bedforms: A synthesis of San Francisco Bay and flume observations
D. M. Rubin, D. S. McCulloch
1980, Sedimentary Geology (26) 207-231
Tidal currents with maximum depth-averaged velocities ranging up to 250 cm/sec have generated ripples, two- and three-dimensional sand waves, and upper flat beds on the floor of central San Francisco Bay. Determination of the hydraulic conditions under which the observed beds exist, indicates that the bed configuration at any point...
Identification of bedforms in lower Cook Inlet, Alaska

1980, Sedimentary Geology (26) 157-177
The seafloor of the central part of lower Cook Inlet, Alaska, is characterized by the presence of different sizes and types of bedforms. The bedforms in the sandy sediments include straight-crested to sinuous to lunate ripples, small, medium, and large sand waves, sand ridges, sand ribbons, and sand patches. In...
Geochronology of archean gneisses in the Lake Helen area, southwestern Big Horn Mountains, Wyoming
Joseph G. Arth, F. Barker, T. W. Stern
1980, Precambrian Research (11) 11-22
The Rb-Sr and U-Pb methods were used to study gneisses in the 712-minute">712-minute Lake Helen quadrangle of the Big Horn Mountains, Wyoming. Two episodes of magmatism, deformation and metamorphism occurred during the Archean. Trondhjemitic to tonalitic orthogneisses and amphibolite of the first episode (E-1) are cut...
First-order analysis of deformation of a thrust sheet moving over a ramp
Philip Berger, Arvid M. Johnson
1980, Tectonophysics (70) T9-T24
John L. Rich introduced the revolutionary concept that many folds in the Appalachian Mountains can be explained as superficial structures formed by passive translation of thrust blocks over ramps in detachment surfaces. The amount of layer-parallel shortening can be negligible in the formation of these folds. Rich primarily was concerned...
Geochemistry of amino acids in shells of the clam Saxidomus
K.A. Kvenvolden, D.J. Blunt, M.A. McMenamin, S.E. Straham
1980, Physics and Chemistry of the Earth (12) 321-332
Concentrations of amino acids and their corresponding dl">dl enantiomeric ratios have been measured in shells of the bivalve mollusk Saxidomus from eleven localities, ranging in age from modern to probably more than 500,000 yr, along the Pacific coast of North America. Natural logarithms of amino acid concentrations correlate...
Preliminary evaluation of lake susceptibility to water-quality degradation by recreational use, Alpine Lakes Wilderness Area, Washington
Robert J. Gilliom, D. P. Dethier, S. A. Safioles, P.L. Heller
1980, Water-Resources Investigations Report 80-1124
The relative susceptibility of lakes in the Alpine Lakes Wilderness Area to water-quality degradation was evaluated from two perspectives: (1) water-quality sensitivity, which is the tendency of a lake 's water quality to degrade in response to pollutant loading, and (2) pollutant-loading likelihood, which is determined by the presence of...

Striped bass hybrids (Morone chrysops female x Morone saxatilis male) confined in a net for 10 minutes had significantly elevated corticosteroid levels (24.2 † 5.4 μg/100 ml) and significant hyperchloremia (150.02 † 2.7 meq/liter), in comparison with baseline levels of 0.8 † 0.1 μg/100 ml and 132.6 † 1.5 meq/liter,...
