Evaluation of pore-water samplers at a drainage ditch, Installation Restoration Site 4, Naval Air Station Corpus Christi, Corpus Christi, Texas, 2005–06
Don A. Vroblesky, Clifton C. Casey
2007, Scientific Investigations Report 2007-5154
The U.S. Geological Survey, in cooperation with the Naval Facilities Engineering Command Southeast, used innovative sampling methods to investigate ground-water contamination by chlorobenzenes beneath a drainage ditch on the southwestern side of Installation Restoration Site 4, Naval Air Station Corpus Christi, Corpus Christi, Texas, during 2005-06. The drainage ditch, which...
Halite brine in the Onondaga Trough near Syracuse, New York: Characterization and simulation of variable-density flow
Richard M. Yager, William M. Kappel, Niel Plummer
2007, Scientific Investigations Report 2007-5058
Halite brine (saturation ranging from 45 to 80 percent) lies within glacial-drift deposits that fill the Onondaga Trough, a 40-km long bedrock valley deepened by Pleistocene ice near Syracuse, N.Y. The most concentrated brine occupies the northern end of the trough, more than 15 kilometers (km) beyond the northern limit...
Hydrology, Water Quality, and Surface- and Ground-Water Interactions in the Upper Hillsborough River Watershed, West-Central Florida
J.T. Trommer, L. A. Sacks, E. L. Kuniansky
2007, Scientific Investigations Report 2007-5121
A study of the Hillsborough River watershed was conducted between October 1999 through September 2003 to characterize the hydrology, water quality, and interaction between the surface and ground water in the highly karstic uppermost part of the watershed. Information such as locations of ground-water recharge and discharge, depth of the...
Sea-floor character and sedimentary processes of Great Round Shoal Channel, offshore Massachusetts
Lawrence J. Poppe, Seth D. Ackerman, David S. Foster, Dann S. Blackwood, S. Jeffress Williams, M. S. Moser, H.F. Stewart, K.A. Glomb
2007, Open-File Report 2007-1138
The imagery, interpretive data layers, and data presented herein were derived from multibeam echo-sounder and sidescan-sonar data collected in the vicinity of Great Round Shoal Channel, the main passage through shoals located at the eastern entrance to Nantucket Sound, Massachusetts, and from the stations occupied to verify these acoustic data...
Mass Wasting Following the 2002 Missionary Ridge Fire near Durango, Colorado, a Field Trip Guidebook
Erica R. Bigio, Robert W. Blair Jr., Michael Burke, Susan H. Cannon, Victor G. deWolfe, John Ey, Joseph E. Gartner, Mary L. Gillam, N.D. Knowlton, Paul M. Santi, William H. Schulz
Jeffrey A. Coe, editor(s)
2007, Open-File Report 2007-1289
This field trip guide focuses on mass wasting following the 2002 Missionary Ridge fire near Durango, Colorado. We prepared this guide to accompany a May 4, 2006, field trip during the second Roy J. Shlemon Specialty Conference, which was held in Durango, Colorado, May 3-5. The conference, entitled Mass Wasting...
Areas Contributing Recharge to Wells in the Tafuna-Leone Plain, Tutuila, American Samoa
Scot K. Izuka, John M. Perreault, Todd K. Presley
2007, Scientific Investigations Report 2007-5167
To address the concerns about the potential for contamination of drinking-water wells in the Tafuna-Leone Plain, Tutuila, American Samoa, a numerical ground-water flow model was developed and used to delineate areas contributing recharge to the wells (ACRWs). Surveys and analyses were conducted to obtain or compile certain essential hydrogeologic information...
Development of a global slope dataset for estimation of landslide occurrence resulting from earthquakes
Kristine L. Verdin, Jonathan W. Godt, Christopher C. Funk, Diego Pedreros, Bruce Worstell, James Verdin
2007, Open-File Report 2007-1188
Landslides resulting from earthquakes can cause widespread loss of life and damage to critical infrastructure. The U.S. Geological Survey (USGS) has developed an alarm system, PAGER (Prompt Assessment of Global Earthquakes for Response), that aims to provide timely information to emergency relief organizations on the impact of earthquakes. Landslides are...
St. Louis Area Earthquake Hazards Mapping Project
Robert A. Williams, Phyllis Steckel, Eugene Schweig
2007, Fact Sheet 2007-3073
St. Louis has experienced minor earthquake damage at least 12 times in the past 200 years. Because of this history and its proximity to known active earthquake zones, the St. Louis Area Earthquake Hazards Mapping Project will produce digital maps that show variability of earthquake hazards in the St. Louis...
Geologic and hydrogeologic information for a geodatabase for the Brazos River Alluvium Aquifer, Bosque County to Fort Bend County, Texas
Sachin D. Shah, Natalie A. Houston
2007, Open-File Report 2007-1031
During July-October 2006, the U.S. Geological Survey (USGS), in cooperation with the Texas Water Development Board (TWDB), developed geologic and hydrogeologic information for a geodatabase for use in development of a Groundwater Availability Model (GAM) of the Brazos River alluvium aquifer along the Brazos River from Bosque County to Fort...
Development of an Impervious-Surface Database for the Little Blackwater River Watershed, Dorchester County, Maryland
Lesley E. Milheim, John Jones, Roger A. Barlow
2007, Open-File Report 2007-1308
Many agricultural and forested areas in proximity to National Wildlife Refuges (NWR) are under increasing economic pressure for commercial or residential development. The upper portion of the Little Blackwater River watershed - a 27 square mile area within largely low-lying Dorchester County, Maryland, on the eastern shore of the Chesapeake...
Size of the California Brown Pelican Metapopulation During a Non-El Nino Year
Daniel W. Anderson, Charles J. Henny, Carlos Godinez-Reyes, Franklin Gress, Eduardo L. Palacios, Karina Santos del Prado, James Bredy
2007, Open-File Report 2007-1299
Overall, we estimated a total metapopulation within the geographical range of the California brown pelican subspecies (Pelecanus occidentalis californicus) as about 70,680 ? 2,640 breeding pairs (mean ? SD). Little change in at least three decades is indicated in the total metapopulation south of the Southern California Bight (SCB) subpopulation,...
