Test drilling in basalts, Lalamilo area, South Kohala District, Hawaii
Warren E. Teasdale
1980, Open-File Report 80-1299
Test drilling has determined that a downhole-percussion airhammer can be used effectively to drill basalts in Hawaii. When used in conjunction with a foam-type drilling fluid, the hammer-bit penetration rate was rapid. Continuous drill cuttings from the materials penetrated were obtained throughout the borehole except from extremely fractured or weathered...
Initial report of the petrophysics laboratory; 1977-1979 addendum
Gary R. Olhoeft
1980, Open-File Report 80-522
From the time the author-copy of Circular 789 (Hunt and others, 1979) was prepared until it first appeared in print, significant changes occurred in the Petrophysics Laboratory. To update that report, this open-file report will briefly summarize more recent acquisitions and facilities changes....
Dinkum Sands
Erk Reimnitz, Robin Ross, Peter W. Barnes
1980, Open-File Report 80-360
The State/Federal Beaufort Sea lease sale in December 1979 attracted over one billion dollars in bids. Tracts with the highest bids, and apparently with the highest oil potential, lie in the area south of Dinkum Sands, and within a three-mile radius of the shoal (Fig. 1). Jurisdiction over the tracts...
Preliminary bathymetry: Approaches to Unakwik Inlet, Alaska
Austin Post
1980, Open-File Report 80-428
A map, scale 1:20,000, shows water depths, rocks, and hazards to navigation. These data are noted on track lines run by the Research Vessel Growler in Alaskan waters, where data on navigation shown on published charts are nonexistant, preliminary, or out dated. ...
Quaternary stratigraphic sections with radiocarbon dates, Wiseman Quadrangle, Alaska
Thomas D. Hamilton
1980, Open-File Report 80-791
The Wiseman quadrangle contains a rich stratigraphic record of alluvial, glacial, and periglacial events of the late Quaternary in the south-central Brooks Range. The numerous bluffs along the Koyukuk River and its tributaries expose drift sheets of the late Pleistocene Itkillik I glacial phase (table 1), and outwash and other...
Preliminary bathymetry of McCarty Fiord and Neoglacial changes of McCarty Glacier, Alaska
Austin Post
1980, Open-File Report 80-424
Preliminary bathymetry (at 1:20,000 scale) and other scientific studies of McCarty Fiord, Alaska, Conducted by the Research Vessel Growler in 1978, showed this 15 mile-long waterway to be a narrow, deeply scoured basin enclosed by a terminal-moraine shoal. This valley was formerly filled by McCarty Glacier, which began a drastic...
Seismicity map of the State of North Carolina
B.G. Reagor, C. W. Stover, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1224
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1977. These data have been reexamined which resulted in some...

Selected chemical quality characteristics in streams of Kentucky, 1970-1975
J.F. Santos
1980, Water-Resources Investigations Report 79-21
Generalized maps of average dissolved solids, hardness and nitrate concentrations of water in streams throughout Kentucky were prepared from data collected at more than 100 sites from 1970 to 1975. Average dissolved solids concentrations seldom exceed 250 milligrams per liter. Hardness, mostly of calcium magnesium origin, generally ranges from 60...
