A geographic information system tool to solve regression equations and estimate flow-frequency characteristics of Vermont Streams
Scott A. Olson, Gary D. Tasker, Craig M. Johnston
2003, Open-File Report 2002-494
Estimates of the magnitude and frequency of streamflow are needed to safely and economically design bridges, culverts, and other structures in or near streams. These estimates also are used for managing floodplains, identifying flood-hazard areas, and establishing flood-insurance rates, but may be required at ungaged sites where no observed flood...
Beaufortian stratigraphic plays in the National Petroleum Reserve - Alaska (NPRA)
David W. Houseknecht
2003, Open-File Report 2003-40
The Beaufortian megasequence in the National Petroleum Reserve in Alaska (NPRA) includes Jurassic through lower Cretaceous (Neocomian) strata of the Kingak Shale and the overlying pebble shale unit. These strata are part of a composite total petroleum system involving hydrocarbons expelled from source rocks in three stratigraphic intervals, the...
Arsenic in New England: Mineralogical and geochemical studies of sources and enrichment pathways
Robert A. Ayuso, Nora K. Foley
2003, Open-File Report 2002-454
Detailed mineralogical, geochemical and radiogenic isotopic studies of iron-sulfide and secondary iron oxy-hydroxide minerals in natural bedrock in coastal Maine and New Hampshire test the link between arsenic-rich sulfide minerals in bedrock and secondary oxy-hydroxide minerals. Samples were selected from over 70 bedrock localities, including 22 within the regionally extensive...
Brookian stratigraphic plays in the National Petroleum Reserve - Alaska (NPRA)
David W. Houseknecht
2003, Open-File Report 2003-39
The Brookian megasequence in the National Petroleum Reserve in Alaska (NPRA) includes bottomset and clinoform seismic facies of the Torok Formation (mostly Albian age) and generally coeval, topset seismic facies of the uppermost Torok Formation and the Nanushuk Group. These strata are part of a composite total petroleum system...
Regional sediment budget of the Columbia River littoral cell, USA: Analysis of bathymetric- and topographic-volume change
Maarten C. Buijsman, C. R. Sherwood, A. E. Gibbs, G. Gelfenbaum, G. M. Kaminsky, P. Ruggiero, J. Franklin
2003, Open-File Report 2002-281
In this Open-File Report we present calculations of changes in bathymetric and topographic volumes for the Grays Harbor, Willapa Bay, and Columbia River entrances and the adjacent coasts of North Beach, Grayland Plains, Long Beach, and Clatsop Plains for four intervals: pre-jetty - 1920s (Interval 1), 1920s - 1950s (Interval...
Results of the U.S. Geological Survey's analytical evaluation program for standard reference samples distributed in September 2002
Mark T. Woodworth, Brooke F. Connor
2003, Open-File Report 2002-481
This report presents the results of the U.S. Geological Survey's analytical evaluation program for six standard reference samples -- T-171 (trace constituents), M-164 (major constituents), N-75 (nutrient constituents), N-76 (nutrient constituents), P-39 (low ionic-strength constituents), and Hg-35 (mercury) -- that were distributed in September 2002 to laboratories enrolled in the...
Occurrence of the diamondback terrapin (Malaclemys terrapin littoralis) at South Deer Island in Galveston Bay, Texas, April 2001-May 2002
Jennifer L. Hogan
2003, Open-File Report 2003-22
One-hundred thirty-five terrapins were captured (116 individuals, 19 recaptures) in occurrence and nesting and basking surveys at South Deer Island in Galveston Bay, Texas, during April 2001–May 2002. Along the southern shore of the island, terrapins were captured in crab traps placed in shallow water offshore; in the lagoon on...
Cascadia Tsunami Deposit Database
Robert Peters, Bruce Jaffe, Guy Gelfenbaum, Curt Peterson
2003, Open-File Report 2003-13
The Cascadia Tsunami Deposit Database contains data on the location and sedimentological properties of tsunami deposits found along the Cascadia margin. Data have been compiled from 52 studies, documenting 59 sites from northern California to Vancouver Island, British Columbia that contain known or potential tsunami deposits. Bibliographical references are provided...
Results of elemental and stable isotopic measurements, and dietary composition of Arctic grayling (Thymallus arcticus) collected in 2000 and 2001 from the Fortymile River Watershed, Alaska
J.G. Crock, R.R. Seal II, L. P. Gough, P. Weber-Scannell
2003, Open-File Report 2003-57
We report the results of the elemental and stable isotopic analyses, as well as the composition of stomach contents, of Arctic grayling (Thymallus arcticus), an ecologically important resident freshwater sport and subsistence fish in the Fortymile River Mining District of the Interior Highlands Ecoregion in eastern Alaska. These data are...
