Generalized gradient and contour program
Marshall Strong Hellman
1972, Computer contribution 22
This program computes estimates of gradients, prepares contour maps, and plots various sets of data provided by the user on the CalComp plotters. The gradients represent the maximum rates of change of a real variable Z=f(X,Y) with respect to the twodimensional rectangle on which the function is defined. The contours...
U.S. Geological Survey National Center, Reston, Virginia
Water Resources Division, U.S. Geological Survey
1972, Report
In 1917 the Geological Survey moved into the newly built Interior Building near the White House in Washington, D. C. Twenty years later a larger building was constructed nearby to house the expanding U. S. Department of the Interior. Height restrictions reduced the planned size of the new building, and...
Appraisal of the future climate of the Holocene in the Rocky Mountains
G.M. Richmond
1972, Quaternary Research (2) 315-322
Consideration of the history of Holocene climate in the Rocky Mountains indicates that the over-all trend during the past 2500 yr has been toward increasing warmth, interrupted by cooler times of minor advances of cirque glaciers. Comparison of Holocene climatic history with the...
Middle pleistocene mollusks from St. Lawrence Island and their significance for the paleo-oceanography of the Bering Sea
D.M. Hopkins, R.W. Rowland, W. W. Patton Jr.
1972, Quaternary Research (2) 119-134
Drift, evidently of Illinoian age, was deposited on St. Lawrence Island at the margin of an ice cap that covered the highlands of the Chukotka Peninsula of Siberia and spread far eastward on the continental shelf of northern Bering Sea. Underlying the drift on the northwestward part of the island...
Pleistocene tectonic accretion of the continental slope off Washington
E. A. Silver
1972, Marine Geology (13) 239-249
Interpretation of reflection profiles across the Washington continental margin suggests deformation of Cascadia basin strata against the continental slope. Individual reflecting horizons can be traced across the slope-basin boundary. The sense of offset along faults on the continental slope is predominantly, but not...
Influence of grounding ice on the Arctic shelf of Alaska
E. Reimnitz, P. Barnes, T. Forgatsch, C. Rodeick
1972, Marine Geology (13) 323-334
Alaska's Beaufort Sea shelf is characterized by small-scale relief with an average amplitude of 1–2 m and wavelength of 50–100 m. Diving observations confirm that much of the bottom roughness reflects the action of grounded ice. Except for areas in the shadow of...
An inventory of suspended sediment stations and type of data analysis for Pennsylvania streams, 1947-1970
Arthur N. Ott, Allen B. Commings
1972, Report
Data concerning suspended sediment concentrations and loads, frequency of occurrence of suspended sediment concentrations, and long-term trends of annual suspended sediment loads are important tools for today's environmental manager. These data are required background for those concerned with establishing and enforcing erosion and sedimentation control regulations and sediment concentration or...
Water quality at Miami International Airport, Miami, Florida, 1971–72
Herbert J. Freiberger, Benjamin F. McPherson
1972, Open-File Report FL 72-023
The quality of water, sediment, and biota was determined at four sites in canals and drainage ditches at Miami International Airport (MIA) during high- and low-water periods and during summer and winter 1971–72. Concentrations of common ions, such as calcium, sodium, chloride, and magnesium, tended to be above average for...
Chryse region, Viking Mars 1975 landing site 3, semicontrolled mosaic
U.S. Geological Survey
1972, Open-File Report 73-323
This semicontrolled mosaic is made with computer enhanced Mariner 9 pictures, transformed to a Mercator projection. Frames were individually scaled for a best fit to the Transverse Mercator projection. Computer processing was performed by the Image Processing Laboratory (IPL) of the Jet Propulsion Laboratory (JPL), California Institute of Technology. Processing...
Stream depletion factors, Arkansas River valley, southeastern Colorado; A basis for evaluating plans for conjunctive use of ground and surface water
C.T. Jenkins, O.J. Taylor
1972, Open-File Report 72-192
The Arkansas River valley is a stream-aquifer system that consists of the Arkansas River and the associated valley-fill deposits. The hydrology, geology, and water-resources development in the valley have been described by Moore and Wood (1967). The history of delivery of irrigation water by canals indicates that the supply has...
Potential transport of sediment from Enloe Reservoir by the Similkameen and Okanogan rivers, Washington
L. M. Nelson
1972, Open-File Report 72-269
This study was undertaken to determine the probable effects on the Similkameen and Okanogan Rivers of the removal, transport, and deposition of sediment now deposited behind Enloe Dam on the Similkameen River, if the dam were removed. Under existing conditions of sediment transport, the average annual suspended-sediment discharges at three streamflow-measuring...
Radiochemical analyses of surface water from U.S. Geological Survey hydrologic bench-mark stations
V.J. Janzer, L.G. Saindon
1972, Open-File Report 72-191
The U.S. Geological Survey's program for collecting and analyzing surface-water samples for radiochemical constituents at hydrologic bench-mark stations is described. Analytical methods used during the study are described briefly and data obtained from 55 of the network stations in the United States during the period from 1967 to 1971 are...
Water resources data for West Virginia, water year 1971; Part 1. Surface water records; Part 2. Water quality records
Water Resources Division, U.S. Geological Survey
1972, Water Data Report WV-71-1
Water resources data for the 1971 water year for West Virginia including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface water, are given in this report. In Part 1, records are...
