Review of Results and Recommendations from the GCMRC 2000-2003 Remote-Sensing Initiative for Monitoring Environmental Resources Within the Colorado River Ecosystem
Philip A. Davis
2004, Open-File Report 2004-1206
In mid-2000, the Grand Canyon Monitoring and Research Center (GCMRC) began a remote-sensing initiative to evaluate all remote-sensing technologies and methods that had potential for providing improved data (capability) for its various programs that monitor the Colorado River ecosystem (CRE). The primary objective of the initiative was to determine the...
Radiochemical and Chemical Constituents in Water from Selected Wells and Springs from the Southern Boundary of the Idaho National Engineering and Environmental Laboratory to the Hagerman Area, Idaho, 2002
Gordon W. Rattray, Linford J. Campbell
2004, Open-File Report 2004-1004
The U.S. Geological Survey, Idaho Department of Water Resources, and the State of Idaho INEEL Oversight Program, in cooperation with the U.S. Department of Energy, sampled water from 17 sites as part of the sixth round of a long-term project to monitor water quality of the eastern Snake River Plain...
National Assessment of Shoreline Change: Part 1, Historical Shoreline Changes and Associated Coastal Land Loss Along the U.S. Gulf of Mexico
Robert A. Morton, Tara L. Miller, Laura J. Moore
2004, Open-File Report 2004-1043
EXECUTIVE SUMMARY Beach erosion is a chronic problem along most open-ocean shores of the United States. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present trends and rates of shoreline movement. There is also a need...
The National Assessment of Shoreline Change: A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for the U.S. Gulf of Mexico
Tara L. Miller, Robert A. Morton, Asbury H. Sallenger Jr., Laura J. Moore
2004, Open-File Report 2004-1089
Introduction The Coastal and Marine Geology Program of the U.S. Geological Survey has generated a comprehensive database of digital vector shorelines and shoreline change rates for the U.S. Gulf of Mexico. These data, which are presented herein, were compiled as part of the U.S. Geological Survey's National Assessment of Shoreline Change...
Results of Electrical Resistivity Data Collected near the Town of Guernsey, Platte County, Wyoming
Robert R. McDougal, Jared D. Abraham, Robert J. Bisdorf
2004, Open-File Report 2004-1095
As part of a study to investigate subsurface geologic conditions as they relate to ground-water flow in an abandoned landfill near the town of Guernsey, Wyoming, geophysical direct current (DC) resistivity data were collected. Eight vertical resistivity soundings and eight horizontal resistivity profiles were made using single channel and multi-channel...
Biosolids, Soil, Crop, Ground-Water, and Streambed-Sediment Data for a Biosolids-Application Area Near Deer Trail, Colorado, 2000
Tracy J.B. Yager, David B. Smith, James G. Crock, Michael R. Stevens
2004, Open-File Report 2003-400
In January 1999, the U.S. Geological Survey began an expanded monitoring program near Deer Trail, Colorado, in cooperation with the Metro Wastewater Reclamation District and the North Kiowa Bijou Groundwater Management District. Monitoring components were biosolids, soils, crops, ground water, and streambed sediments. The monitoring program addresses concerns from the public...
Chemical analyses of tertiary volcanic rocks, central San Juan caldera complex, southwestern Colorado
Peter W. Lipman
2004, Open-File Report 2004-1194
In conjunction with integrated mapping of the Oligocene central San Juan caldera cluster, southwestern Colorado (USGS I-Map 2799, in press), all modern chemical analyses of volcanic rocks for this area determined in laboratories of the U.S. Geological Survey have been re-evaluated in terms of the stratigraphic sequence as presently understood....
The Cottage Lake aeromagnetic lineament: A possible onshore extension of the southern Whidbey Island fault, Washington
Richard J. Blakely, Brian L. Sherrod, Ray E. Wells, Craig S. Weaver, David H. McCormack, Kathy G. Troost, Ralph A. Haugerud
2004, Open-File Report 2004-1204
The northwest-striking southern Whidbey Island fault zone (SWIF) was mapped previously using borehole data and potential-field anomalies on Whidbey Island and marine seismic surveys beneath surrounding waterways. Abrupt subsidence at a coastal marsh on south-central Whidbey Island suggests that the SWIF experienced a MW 6.5 to 7.0 earthquake about 3000...
Selected natural attenuation monitoring data, Operable Unit 1, Naval Undersea Warfare Center, Division Keyport, Washington, June 2002
Richard S. Dinicola
2004, Open-File Report 2004-1203
Previous investigations indicated that natural attenuation and biodegradation of chlorinated volatile organic compounds (CVOCs) are substantial in shallow ground water beneath the 9-acre former landfill at Operable Unit 1 (OU 1), Naval Undersea Warfare Center (NUWC), Division Keyport, Washington. The U.S. Geological Survey (USGS) has continued to monitor ground-water geochemistry...
Assessment of Hazards Associated with the Bluegill Landslide, South-Central Idaho
William L. Ellis, Robert L. Schuster, William H. Schulz
2004, Open-File Report 2004-1054
The Bluegill landslide, located in south-central Idaho, is part of a larger landslide complex that forms an area the Salmon Falls Creek drainage named Sinking Canyon Recent movement of the Bluegill landslide, apparently beginning sometime in late 1998 or early 1999, has caused a 4.5 ha area of the canyon...
Preliminary geologic map of the Big Bear City 7.5' Quadrangle, San Bernardino County, California
Fred K. Miller, Pamela M. Cossette
2004, Open-File Report 2004-1193
This data set maps and describes the geology of the Big Bear City 7.5' quadrangle, San Bernardino County, California. Created using Environmental Systems Research Institute's ARC/INFO software, the data base consists of the following items: (1) a rock-unit coverage and attribute tables (polygon and arc) containing geologic contacts, units and...
Sediment grain-size and loss-on-ignition analyses from 2002 Englebright Lake coring and sampling campaigns
Noah P. Snyder, James R. Allen, Carlin Dare, Margaret A. Hampton, Gary Schneider, Ryan J. Wooley, Charles N. Alpers, Mark C. Marvin-DiPasquale
2004, Open-File Report 2004-1080
This report presents sedimentologic data from three 2002 sampling campaigns conducted in Englebright Lake on the Yuba River in northern California. This work was done to assess the properties of the material deposited in the reservoir between completion of Englebright Dam in 1940 and 2002, as part of the Upper...
Catalog of significant historical earthquakes in the Central United States
W. H. Bakun, M. G. Hopper
2004, Open-File Report 2004-1086
We use Modified Mercalli intensity assignments to estimate source locations and moment magnitude M for eighteen 19th-century and twenty early- 20th-century earthquakes in the central United States (CUS) for which estimates of M are otherwise not available. We use these estimates, and locations and M estimated elsewhere, to compile a...
Predicted seafloor facies of Central Santa Monica Bay, California
Peter Dartnell, James V. Gardner
2004, Open-File Report 2004-1081
Summary -- Mapping surficial seafloor facies (sand, silt, muddy sand, rock, etc.) should be the first step in marine geological studies and is crucial when modeling sediment processes, pollution transport, deciphering tectonics, and defining benthic habitats. This report outlines an empirical technique that predicts the distribution of seafloor facies for...
