Blind comparisons of shear-wave velocities at closely-spaced sites in San Jose, California: Proceedings of a Workshop held at the US Geological Survey, Menlo Park, May 3, 2004
Michael W. Asten, David M. Boore, editor(s)
2005, Open-File Report 2005-1169
Shear-wave velocities within several hundred meters of Earth's surface are important in specifying earthquake ground motions for engineering design. Not only are the shearwave velocities used in classifying sites for use of modern building codes, but they are also used in site-specific studies of particularly significant structures. Many are the...
Potentiometric surface of the upper Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, September 2004
Sandra L. Kinnaman
2005, Open-File Report 2005-1202
Introduction: This map depicts the potentiometric surface of the Upper Floridan aquifer in the St. Johns River Water Management District and vicinity in September 2004. Potentiometric contours are based on water-level measurements collected at 608 wells during the period September 14-October 1, near the end of the wet season....
Height changes along selected lines through the Death Valley region, California and Nevada, 1905-1984
Robert O. Castle, Thomas D. Gilmore, James P. Walker, Susan A. Castle
2005, Open-File Report 2005-1133
Comparisons among repeated levelings along selected lines through the Death Valley region of California and adjacent parts of Nevada have disclosed surprisingly large vertical displacements. The vertical control data in this lightly populated area is sparse; moreover, as much as a third of the recovered data is so thoroughly contaminated...
Porphyry copper deposits of the world: database, map, and grade and tonnage models
Donald A. Singer, Vladimir Iosifovich Berger, Barry C. Moring
2005, Open-File Report 2005-1060
Mineral deposit models are important in exploration planning and quantitative resource assessments for two reasons: (1) grades and tonnages among deposit types are significantly different, and (2) many types occur in different geologic settings that can be identified from geologic maps. Mineral deposit models are the keystone in combining the...
Thermal maturity patterns (CAI and %Ro) in the Ordovician and Devonian rocks of the Appalachian basin in West Virginia
John E. Repetski, Robert T. Ryder, Katharine Lee Avary, Michael H. Trippi
2005, Open-File Report 2005-1078
The objective of this study is to enhance existing thermal maturity maps in West Virginia by establishing: 1) new subsurface CAI data points for the Ordovician and Devonian and 2) new %Ro and Rock Eval subsurface data points for Middle and Upper Devonian black shale units. Thermal maturity values for...
Coastal change rates and patterns: Kaloko-Honokohau National Historical Park, Hawai'i
Cheryl J. Hapke, Rick Gmirkin, Bruce M. Richmond
2005, Open-File Report 2005-1069
A collaborative project between the U.S. Geological Survey's Coastal and Marine Geology Program and the National Park Service (NPS) has been developed to create an inventory of geologic resources for National Park Service lands on the Big Island of Hawai'i. The NPS Geologic Resources Inventories are recognized as essential for...
Major- and trace-element concentrations in soils from two continental-scale transects of the United States and Canada
David B. Smith, William F. Cannon, Laurel G. Woodruff, Robert G. Garrett, Rodney Klassen, James E. Kilburn, John D. Horton, Harley D. King, Martin B. Goldhaber, Jean M. Morrison
2005, Open-File Report 2005-1253
This report contains major- and trace-element concentration data for soil samples collected from 265 sites along two continental-scale transects in North America. One of the transects extends from northern Manitoba to the United States-Mexico border near El Paso, Tex. and consists of 105 sites. The other transect approximately follows the...
Mercury recycling in the United States in 2000
William E. Brooks, Grecia R. Matos
2005, Open-File Report 2005-1236
Reclamation and recycling of mercury from used mercury- containing products and treatment of byproduct mercury from gold mining is vital to the continued, though declining, use of this metal. Mercury is reclaimed from mercury-containing waste by treatment in multistep high-temperature retorts-the mercury is volatized and then condensed for purification and...
Flood of September 18-19, 2004 in the Upper Delaware River Basin, New York
Lloyd T. Brooks
2005, Open-File Report 2005-1166
The interaction between the remnants of tropical depression Ivan and a frontal boundary in the upper Delaware River basin on September 18-19, 2004, produced 4 to more than 6 inches of rainfall over a 5-county area within a 24-hour period. Significant flooding occurred on the East Branch Delaware River and...
A guide to the proper selection and use of federally approved sediment and water-quality samplers
Broderick E. Davis, Federal Interagency Sedimentation Project
2005, Open-File Report 2005-1087
The Federal Interagency Sedimentation Project (FISP) was created in 1939 to unify and standardize the research and development activities of Federal agencies involved in fluvial sediment studies1,2. Research and development conducted by the FISP originally focused on hydraulic and mechanical aspects of sediment sampling. The mission of the FISP has...
Managing Fire in the Northern Chihuahuan Desert: A Review and Analysis of the Literature
Brooke S. Gebow, William L. Halvorson
2005, Open-File Report 2005-1157
Executive Summary This report began as a literature review (Gebow and Halvorson 2001) conducted for fire planners at Carlsbad Caverns National Park who were seeking information about (1) the natural state of park vegetation, (2) northern Chihuahuan Desert natural fire regimes, and (3) fire effects on park plant species. It is...
