Tables showing analyses of semiquantitative spectrometry and atomic-absorption spectrophotometry of rock samples collected in the Ugashik, Bristol Bay, and western part of the Karluk quadrangles, Alaska
Frederic H. Wilson, Richard M. O’Leary
1987, Open-File Report 87-419
The accompanying tables list chemical analyses of 337 rock samples that were collected in 1979, 1980, and 1981 in conjunction with geologic mapping in the Ugashik, Bristol Bay, and part of Karluk quadrangles. This work was conducted under the auspices of the Alaska Mineral Resource Assessment Program (AMRAP). This report...
Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-87 and 1986-87, and measured compaction, 1973-87, in the Houston-Galveston region, Texas
James F. Williams III, C.E. Ranzau Jr., W.B. Lind
1987, Open-File Report 87-108
This report consists of: (1) four maps that present data on water level changes during 1977-87 and 1986-87 in the Chicot and Evangeline aquifers, and in the Houston-Galveston region, Texas, and (2) one set of graphs and one map that present data on land subsidence caused by compaction of sub-surface...
Selected hydrogeologic data for the southwest Glendive Preliminary Logical Mining Unit and adjacent areas, Dawson County, Montana
R.S. Roberts
1987, Open-File Report 87-390
Hydrogeologic data were collected from a coal area in Dawson County, Montana, to provide a basis for identifying and characterizing the groundwater resources. Inventory records for 72 domestic, stock, irrigation, unused, and observation wells are tabulated in the report; the data were collected principally from 1977 through 1981. The location...
Preprocessor and postprocessor computer programs for a radial-flow finite-element model
A. A. Pucci Jr., D. A. Pope
1987, Open-File Report 87-680
Preprocessing and postprocessing computer programs that enhance the utility of the U.S. Geological Survey radial-flow model have been developed. The preprocessor program: (1) generates a triangular finite element mesh from minimal data input, (2) produces graphical displays and tabulations of data for the mesh , and (3) prepares an input...
A review of circulation and mixing studies of San Francisco Bay, California
L. H. Smith
1987, Open-File Report 87-534
A description of the major characteristics and remaining unknowns of circulation and mixing in San Francisco Bay has been constructed from a review of published studies. Description of net circulation and mixing over a few days to a few months illustrates best the interactions of major components. The discharge of...
Manmade organic compounds in the surface waters of the United States: a review of current understanding
James A. Smith, Patrick J. Witkowski, Thomas V. Fusillo
1987, Open-File Report 87-209
This report reviews the occurrence and distribution of manmade organic compounds in the surface waters of the United States. On the basis of their aqueous solubilities, nonionic organic compounds partition themselves between water, dissolved organic matter, particulate organic matter, and the lipid reservoirs of aquatic organisms. Ionized organic compounds can...
Seismicity map of the state of New York
C. W. Stover, B.G. Reagor, L.M. Highland, S. T. Algermissen
1987, Miscellaneous Field Studies Map 1282
This map is one of a series of seismicity maps produced by the U.S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000.  This map shows only those earthquakes with epicenters located within the boundaries of New York, even though earthquakes...
