Summaries of data on and lists of references to metallic and selected nonmetallic mineral deposits in the Blying Sound and Seward quadrangles, Alaska
1980, Open-File Report 80-621
These summaries of data on metallic and selected nonmetallic mineral occurrences and lists of selected references to them in Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys (and predecessor State and Territorial agencies) reports and maps and a very few journal articles...
Bulletin of the Seismological Laboratory for the period from 1 January 1975 to 31 December 1979
G.M. Smith, F.D. Ryall
1980, Open-File Report 81-231
This issue of the Bulletin of the Seismological Laboratory summarizes the determination of epicenters for earthquakes located in the western Great Basin, Nevada and eastern California, for the period 1975-1979. The Laboratory attempts to identify and locate all earthquakes with ML greater than about 2.5 in this region. Quality of...
Water-resources investigations of the U.S. Geological Survey in Missouri : fiscal year 1980
Wanietia M. Kratzer
1980, Open-File Report 80-1019
Water-resources investigations of the U.S. Geological Survey in Missouri consist of collecting hydrologic data and conducting interpretative investigations. The data and the results of the investigations are published or released by either the U.S. Geoloogical Survey or by cooperating agencies. The report describes the data-collection activities and investigations in Missouri...
Summaries of data on and lists of references to metallic and selected nonmetallic mineral deposits in the Big Delta and Tanacross quadrangles, Alaska
1980, Open-File Report 80-1086
These summaries of data on metallic and selected nonmetallic mineral occurrences and lists of selected references to them in Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys (and predecessor State and Territorial agencies) reports and maps released before Jan. 1, 1980, are...
Instructions for the preparation of data for the master water data index
Melvin D. Edwards, William A. Knecht
1980, Open-File Report 80-415
The Master Water Data Index (MWDI) of the U.S. Geological Survey's National Water Data Exchange (NAWDEX) is a computerized data base which contains information about water data collected at specific sites. The data base identifies the organization collecting the data, the site location, the major types of data collected, the...
Water resources data for Georgia, water year 1979
Water Resources Division, U.S. Geological Survey
1980, Water Data Report GA-79-1
Water resources data for the 1979 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 100 gaging stations; stage for 10 gaging stations; stage and contents for 17...
Ground water in Osceola County, Florida
James M. Frazee Jr.
1980, Open-File Report 79-1595
This report describes the ground-water resources of Osceola County, Florida, with emphasis on the (1) location of the principal aquifers, (2) location of areas of ground-water recharge and discharge, (3) chemical quality of ground water, and (4) quantities of ground water available. The investigation includes an inventory of 365 wells,...
Calibration and potential uses of a digital water-quality model for the Arkansas River in Pueblo County, Colorado
Kimball E. Goddard
1980, Water-Resources Investigations Report 80-38
The U.S. Geological Survey conducted a 1-year study to calibrate and demonstrate the use of a steady-state water quality model for a 42-mile reach of the Arkansas River in Pueblo County, Colo. Based on the calibration, the model is capable of accurately predicting concentrations of carbonaceous biochemical oxygen demand, total...
Using channel geometry to estimate flood flow at ungaged sites in Idaho
W. A. Harenberg
1980, Water-Resources Investigations Report 80-32
Measurements at bankfull stage were made at 136 sites to determine whether predictions of flood discharges using channel-geometry characteristics are as good as or better than predictions using basin characteristics. These measurements are used to determine the variables of bankfull width, area, depth, and velocity. These variables are combined with...
Distribution of trace elements in bottom sediment of the northern Bering Sea
Bradley R. Larsen, C. Hans Nelson, Chris Heropoulos, Jeffrey J. Patry
1980, Open-File Report 80-399-A
2-dimensional contour and 3-dimensional value-surface maps of semi-quantitative emission spectographic analyses for over 50 elements in surface sediment from 180 sampling stations are presented. For purposes of discussion, certain of these elements have been grouped into the following categories: petroleum indicators, heavy metals, potentially toxic elements, chemically sensitive elements, major...
