A possible petroleum related helium anomaly in the soil gas, Boulder and Weld Counties, Colorado
Alan A. Roberts, M.C. Dalziel, L.A. Pogorski, S.G. Quirt
1976, Open-File Report 76-544
A survey of the concentrations of helium in the soil gas conducted over a portion of the Denver Basin in Boulder and Weld Counties, Colorado, supports the existence of a potential petroleum prospect that was suggested by earlier geochemical analyses of the outcropping sandstones. The helium survey technique may prove...
Monitoring irrigated land acreage using Landsat imagery: an application example
William C. Draeger
1976, Open-File Report 76-630
A demonstration of the utility of Landsat imagery for quickly and cheaply estimating irrigated land area was conducted in the Klamath River basin of Oregon. Landsat color composite images, at 1:250,000 scale and acquired on two dates during the 1975 growing season, were interpreted. Irrigated lands were delineated manually, and...
Outline of the water resources of the Status Creek basin, Yakima Indian Reservation, Washington
Dee Molenaar
1976, Open-File Report 76-808
On the Yakima Indian Reservation, Washington, only about 5 percent of the Satus Creek basin--in the relatively flat eastern lowland adjacent to and including part of the Yakima River lowland--is agriculturally developed, mostly through irrigation. Because the basin 's streams do not contain adequate water for irrigation, most irrigation is...
Machine-assisted analysis of Landsat data in the study of crop-soils relationships
William C. Draeger
1976, Open-File Report 76-603
To date, relatively few studies have dealt with crop-soil interactions as they affect the appearance of agricultural areas on Landsat imagery, and hence crop and soil classification or the analysis of agricultural land use.The Image 100, a computer-based data analysis system which allows an interpreter to interact directly and rapidly with Landsat computer...
Channel erosion surveys along TAPS route, Alaska, 1976
Paul F. Doyle, Joseph M. Childers
1976, Open-File Report 77-170
Channel surveys were made along the TAPS route during 1976 at the same 27 sites that were surveyed in 1975. One additional site was put under surveillance in 1976. Except for construction changes wrought by installation of the pipeline, most of the sites surveyed showed very little change since the...
Preliminary report on uranium-, thorium-, and rare-earth-bearing rocks near Golovin, Alaska
Thomas P. Miller, Raymond L. Elliott, Warren I. Finch, Robert A. Brooks
1976, Open-File Report 76-710
Uranium-, thorium-, and rare-earth bearing rocks were found by a U.S. Geological Survey field party 15 miles northeast of Golovin, Alaska, in  the southeastern Seward Peninsula (fig. 1) in June 1976. The mineralized areas occur in syenite and appear to be concentrated along the margins of alkaline dikes, with allanite...
Water-quality data for the Southern Ute Indian Reservation, southwestern Colorado
E. Carter Hutchinson, Robert E. Brogden
1976, Open-File Report 76-16
Water-quality data from a study by the U.S. Geological Survey on the Southern Ute Indian Reservation in southwestern Colorado are presented in two tables. The data were collected during 1973-76 from 338 ground-water and surface-water samples. All samples were analyzed for major catons and anions, and selenium and arsenic. Data...
Salt-water encroachment in aquifers near the Houston Ship Channel, Texas
Donald G. Jorgensen
1976, Open-File Report 76-781
Interpretations based on analyses of inorganic constituents, dissolved organic carbon, and tritium in ground water and surface waters indicate that the Houston Ship Channel is the source of salt water that has been detected in shallow wells between Baytown and Houston, Texas. Analyses of the ratios of the stable isotopes...
Shallow sedimentary framework of Georges Bank
R. S. Lewis, R. E. Sylwester
1976, Open-File Report 76-874
Two thousand nine hundred kilometers of minisparker data were collected on Georges Bank by the United States Geological Survey during October of 1975. Several sedimentary features have been observed in the data, The bank is recognized as a compound feature resulting from erosion of Tertiary coastal-plain strata followed by deposition...
