A study of trends in dissolved oxygen and fecal coliform bacteria at NASQAN stations
Richard A. Smith, Richard B. Alexander
1982, Open-File Report 82-1019
Most stations in the U.S. Geological Survey's National Stream Quality Accounting Network show no significant trend in either dissolved oxygen concentration or fecal coliform bacteria population for the period October 1974. through October 1981. Of the stations which do show trends, however, most show improved water quality: thirty-one of a...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: June 1982
John B. Townshend, J.E. Papp, E.A. Sauter, L.Y. Torrence, T.K. Cunningham
1982, Open-File Report 82-300-F
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Magnitude and frequency of floods from selected drainage basins in South Dakota
Lawrence D. Becker
1982, Water-Resources Investigations Report 82-31
The 2-, 5-, 10-, 25-, 50-, and 100-year floods are determined for gaged sites on 120 selected, small drainage basins in South Dakota. These estimates are from the frequency curves defined from the streamflow records. Short-term records for 66 sites were extended on the basis of long-term climatic records and...
Water resources data, Florida, water year 1981; Volume 2B. South Florida ground water
Water Resources Division, U.S. Geological Survey
1982, Water Data Report FL-81-2B
Water resources data for the 1981 water year for south Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
Fluid-inclusion data on samples from Creede, Colorado, in relation to mineral paragenesis
T.L. Woods, Edwin Roedder, P. M. Bethke
1982, Open-File Report 82-313
Published and unpublished data on 2575 fluid inclusions in ore and gangue minerals from the Creede, Colorado, Ag-Pb-Zn-Cu vein deposit collected in our laboratories from 1959 to 1981 have shown that the average salinity (wt. % NaCl equivalent, hereinafter termed wt.% eq.) and homogenization temperature (Th), and the ranges of...
Palaeocopid and podocopid Ostracoda from the Lexington Limestone and Clays Ferry Formation (Middle and Upper Ordovician) of central Kentucky
S.M. Warshauer, J.M. Berdan
1982, Professional Paper 1066-H
The Middle through lower Upper Ordovician Lexington Limestone and lower part of the Clays Ferry Formation contain an abundant and diversified ostracode fauna. More than 10,000 specimens belonging to 39 genera and 53 species have been found in 73 collections made by members of the U.S. Geological Survey in cooperation...
Statistical summaries of water-quality data for two coal areas of Jackson County, Colorado
Gerhard Kuhn
1982, Open-File Report 82-121
Statistical summaries of water-quality data are compiled for eight streams in two separate coal areas of Jackson County, Colo. The quality-of-water data were collected from October 1976 to September 1980. For inorganic constituents, the maximum, minimum, and mean concentrations, as well as other statistics are presented; for minor elements, only...
CONTOUR; a modification of G.I. Evenden's general purpose contouring program
R. H. Godson, M. W. Webring
1982, Open-File Report 82-797
A contouring program written for the DEC-10 computer (Evenden, 1975) has been modified and enhanced to operate on a Honeywell Multics 68/80 computer. The program uses a device independent plotting system (Wahl, 1977) so that output can be directed to any of several plotting devices by simply specifying one input...
