Reconnaissance snow surveys of the National Petroleum Reserve in Alaska, April 1977 and April-May 1978
Charles E. Sloan, Dennis Trabant, William Glude
1979, Open-File Report 79-1342
Reconnaissance snow surveys of the NPRA (National Petroleum Reserve in Alaska) were made in April 1977 and April-May 1978 to ascertain general snow characteristics and distribution patterns. Thirty-nine sites in 1977 and forty-one sites in 1978 were sampled to determine snow depth, density, structure, and snow-soil interface temperature. In addition,...
Knik Glacier, Alaska, May 1979 monument and glacier survey
Dennis C. Trabant, L.R. Mayo
1979, Open-File Report 80-48
From 1915, or earlier, to 1966, with the exception of 1963, Knik Glacier annually formed and released Lake George, the largest glacier-dammed lake in Alaska. Eleven geodetically controlled survey stations were defined in the basin, and 22 glacier surface altitudes were measured. This is the first effort in a continuing...
Occurrence of uranium in rocks of the intrusive complex at Ekiek Creek, western Alaska
Alan R. Wallace
1979, Open-File Report 79-1653
Uranium in the Ekiek Creek Complex of western Alaska is related to a niobium-rich pyrochlore in the nepheline syenite of the complex. The complex consists of an aegirine-phlogopite pyroxenite that has been intruded and partly replaced by nepheline syenite. The contact zone between the two igneous units varies from a...
Availability of palynomorph and foraminifera microscope slides from test wells of National Petroleum Reserve in Alaska; group 1
Roger J. Witmer
1979, Open-File Report 80-193
The first group of palynomorph (pollen, spores, dinoflagellates, acritarchs) and Foraminifera microscope slides prepared from test wells drilled during the National Petroleum Reserve in Alaska (N.P.R.A.) program and the earlier Naval Petroleum Reserve No. 4 (N.P.R.-4) program are now being made available for examination. Jurisdiction of N.P.R.-4 was transferred from...
Sediment transport in the Tanana River in the vicinity of Fairbanks, Alaska, 1977-78
Robert L. Burrows, Bruce Parks, William W. Emmett
1979, Open-File Report 79-1539
Measurements of the sediment load of the Tanana River in the vicinity of Fairbanks, Alaska, show that suspended-sediment transport rate in tons per day, relates to water discharge, in cubic feet per second, as: Suspended-sediment transport rate (tons/day) = 5.717 x 10 to the minus 8th power x water discharge...
Catalog of earthquakes in southern Alaska: January-March 1978
C.D. Stephens, J.C. Lahr, K.A. Fogleman, M.A. Allan, S.M. Helton
1979, Open-File Report 79-718
The National Center for Earthquake Research of the U.S. Geological Survey (USGS) began a program of telemetered seismic recording in south-central Alaska in 1971. The principal objectives of this program have been to use data recorded by this network to precisely locate earthquakes in the active seismic zones of southern...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Mount Hayes Quadrangle, Alaska
Edward Huntington Cobb
1979, Open-File Report 79-238
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Mount Hayes quadrangle, Alaska. References to most reports of the Geological Survey, the U.S. Bureau of Mines, and the State of Alaska Division of...
Analyses of surficial deposits, central Brooks Range, Alaska
Thomas D. Hamilton, James H. Trexler, James McCalpin
1979, Open-File Report 79-228
Seventy-nine sediment samples from the central Brooks Range were analyzed for grain-size distribution, shape and composition of grains, and other physical properties. Four statistical measures (sorting, mean diameter, skewness, and kurtosis) were then computed for the sand-to-clay size fraction of all samples.Fan sediments resemble the other alluvial-gravel deposits in consisting...
Resource report for proposed OCS lease sale 57: Norton Basin, Alaska
Michael A. Fisher, W.W. Patton, D.R. Thor, M.L. Holmes, E. W. Scott, C.H. Nelson, C.L. Wilson
1979, Open-File Report 79-720
This report is a summary of information about an area of the northern Bering Sea continental shelf that is bounded by the Seward Peninsula on the north, by the line of the United States-Russia Convention of 1867 on the west, and by St. Lawrence Island and the coastline that rims...
Arsenic, nitrate, iron, and hardness in ground water, Fairbanks area, Alaska
Paula R. Johnson, D.E. Wilcox, W.D. Morgan, Josephine Merto, Ruth McFadden
1979, Open-File Report 78-1034
Well water with concentrations of arsenic and nitrate exceeding U.S. Environmental Protection Agency standards occurs sporadically throughout the hills north of Fairbanks, Alaska. The arsenic contamination has not been correlated with placer or other mining activity. The high levels of nitrate do not generally appear related to septic waste contamination....
