Channel erosion surveys along proposed TAPS route, Alaska, July 1971
Joseph M. Childers
1972, Report
The U.S. Geological Survey has the threefold responsibility along the proposed route of the Trans-Alaska Pipeline System (TAPS): to investigate possible hydroloqic hazards to the pipeline, to investigate possible impacts of the pipeline on water resources, and to develop a better understanding of Arctic hydrology. Because the proposed pipeline route...
A land use classification scheme for use with remote sensor data
Water Resources Division, U.S. Geological Survey
1972, Book
The needs of Federal agencies for a broad overview of national land use patterns, trends, and environmental impacts, with data inputs from both conventional sources and some of the more exotic sensors in high altitude aircraft and satellite platforms led to the formation in early 1971 of an Inter-Agency Steering...
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...
A preliminary study of peat resources in eastern Maine
Cornelia Clermont Cameron
1972, Open-File Report 72-60
Nineteen peat deposits in southeastern Aroostook County (fig. 1) contain an estimated 4,987,000 tons of peat. The location, size and quality data for each deposit are given in tables 1, 2 and 3. Thirty-eight deposits in Washington County (fig. 2) contain an estimated 20,041,000 tons of peat. The location, size...
Ground-water hydrology of prairie potholes in North Dakota
C. E. Sloan
1972, Professional Paper 585-C
Prairie potholes (sloughs) are water-holding depressions of glacial origin in the prairies of the Northern United States and southern Canada. Water is supplied to the potholes by precipitation on the water surface, basin runoff, and seepage inflow of ground water. Depleticn of pothole water results from evapotranspiration, overflow, and seepage...
Office of International Geology reports resulting from U.S. Geological Survey participation in the United States Technical Assistance Program bibliographic supplement for 1968-1971
Wenonah E. Bergquist, Lloyd Lynch, Mary M. Brister
1972, Open-File Report 72-35
U. S. Geological Survey Bulletin 1263, by Jo Ann Heath and Nancy B. Tabacchi, lists the reports that resulted from a wide variety of geologic and hydrologic investigations, and institutional development programs undertaken by the U. S. Geological Survey and counterpart agencies during the period 1940 to 1967. This supplementary...
The hydraulic geometry of some Alaskan streams south of the Yukon River
William W. Emmett
1972, Open-File Report 72-108
Channel geometry surveys were conducted to determine bankfull stage, discharge, and other hydraulic parameters at 22 locations along the proposed route of the trans-Alaska pipeline corridor south of the Yukon River. Combined with the records from gaging stations located at some of the sites, the data are sufficient to describe...
Vegetation of prairie potholes, North Dakota, in relation to quality of water and other environmental factors
R. E. Stewart, H.A. Kantrud
1972, Professional Paper 585-D
Measurements of specific conductance provide an adequate indication of the average salinity of surface waters in natural ponds and lakes of the northern .prairie region. Yearly and seasonal variations in specific conductance were much greater in brackish and subsaline wetlands than in fresh-water areas. The principal vegetational types. Land-use practices...
