Graded storm sand layers offshore from the Yukon Delta, Alaska
C. Hans Nelson
1980, Open-File Report 80-712
The northern Bering Sea has a history of severe storm surges. The most recent, and perhaps the worst in historical times, occurred in November, 1974 (Fathauer, 1975). Evidence of storm surge events is exhibited in sea-floor stratigraphy as well as shoreline flooding and indicates that significant widespread changes in sea-floor...
Hydrogeology of the Seldovia area, Alaska
Gordon L. Nelson, Wesley R. Danskin
1980, Open-File Report 80-952
Surficial materials in the Seldovia area, Alaska, are mapped as glacial drift over sedimentary bedrock, glacial drift over igneous and metamorphic bedrock, valley-bottom, alluvium, alluvial fan deposits, beach and intertidal deposits, and peat. Unconsolidated materials are generally less than 10 feet thick except in well-drained glacial deposits along the Seldovia-Jakolof...
Description and preliminary map of airborne electromagnetic survey of parts of Iron, Baraga, and Dickinson Counties, Michigan
William D. Heran, Bruce D. Smith
1980, Open-File Report 80-297
The data presented herein is from an airborne electromagnetic INPUT* survey conducted by Geoterrex Limited of Canada for the U.S. Geological Survey. The survey area is located in the central part of the Upper Peninsula of Michigan, within parts of Iron, Baraga, and Dickinson Counties. The general area covered is...
Potentiometric surface of the Floridan Aquifer, Southwest Florida Water Management District, September 1980
D. K. Yobbi, W. M. Woodham, George R. Schiner
1980, Open-File Report 80-1280
A September 1980 potentiometric-surface map of the Southwest Florida Water Management District depicts the annual high water-level period. Potentiometric levels rose 1 to 31 feet between May 1980 and September 1980 in the citrus and farming sections of southern Hillsborough, northern Hardee, southwestern Polk, northwestern DeSoto, and Manatee Counties. Water...
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...
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. ...
Preliminary map showing freshwater heads for the Mission Canyon and Lodgepole limestones and equivalent rocks of Mississippian age in the Northern Great Plains of Montana, North Dakota, South Dakota, and Wyoming
W. Roger Miller, S.A. Strausz
1980, Open-File Report 80-729
A potentiometric-surface map showing freshwater heads for the Mission Canyon and Lodgepole Limestones of Mississippian age has been prepared as part of a study to determine the water-resources potential of the Mississippian Madison Limestone and associated rocks in the Northern Great Plains of Montana, North and South Dakota, and Wyoming....
Preliminary free-air gravity map, Norton Basin, Alaska
Michael A. Fisher, P.H. McClellan, M.L. Holmes, J.R. Childs
1980, Open-File Report 80-1068
Gravity data shown here were measured with LaCoste and Romberg sea gravimeter S-53 mounted on a 3 axis inertial platform (LaCoste and others, 1967, Valiant and LaCoste, 1976). Primary navigation was by satellite, integrated with course and speed measurements from doppler sonar and gyrocompass. Gravity data were filtered prior to...
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....
Preliminary map showing freshwater heads for the Red River Formation, Bighorn Dolomite, and equivalent rocks of Ordovician age in the Northern Great Plains of Montana, North Dakota, South Dakota, and Wyoming
W. Roger Miller, S.A. Strausz
1980, Open-File Report 80-730
A map showing freshwater heads for the Ordovician Red River Formation, Bighorn Dolomite, and equivalent rocks has been prepared as part of a study to determine the water-resources potential of the Mississippian Madison Limestone and associated rocks in the Northern Great Plains of Montana, North and South Dakota, and Wyoming....
