By selecting one of the four series options shown below, namely, -A, -B, -C, and -D for the geologic, topographic, Landsat natural-color, and Landsat false-color maps, respectively, the user will be taken to that map....
Magnetic anomalies in East Antarctica: a window on major tectonic provinces and their boundaries
A.V. Golynsky
2007, Open-File Report 2007-1047-SRP-006
An analysis of aeromagnetic data compiled within the Antarctic Digital Magnetic Anomaly Project (ADMAP) yields significant new insight into major tectonic provinces of East Antarctica. Several previously unknown crustal blocks are imaged in the deep interior of the continent, which are interpreted as cratonic nuclei. These cratons are fringed by...
Factors affecting the reproduction, recruitment, habitat, and population dynamics of pallid sturgeon and shovelnose sturgeon in the Missouri River
Carl E. Korschgen, editor(s)
2007, Open-File Report 2007-1262
For more than a hundred years, human activities have modified the natural forces that control the Missouri River and its native fish fauna. While the ecological effects of regulation and channel engineering are understood in general, the current understanding is not sufficient to guide river restoration and management. The U.S....
Two-Dimensional Simulation of Flow and Evaluation of Bridge Scour at Structure A-1700 on Interstate 155 over the Mississippi River near Caruthersville, Missouri
Richard J. Huizinga
2007, Scientific Investigations Report 2007-5230
The evaluation of scour at bridges throughout the State of Missouri has been ongoing since 1991, and most of these evaluations have used one-dimensional hydraulic analysis and application of conventional scour depth prediction equations. Occasionally, the complex conditions of a site dictate a more thorough assessment of the stream hydraulics...
Characterization of Water Quality in Unmonitored Streams in the Mississippi Alluvial Plain, Northwestern Mississippi, May-June 2006
Jeannie R. Bryson, Richard H. Coupe, Michael A. Manning
2007, Scientific Investigations Report 2007-5116
The Mississippi Department of Environmental Quality is required to develop restoration and remediation plans for water bodies not meeting their designated uses, as stated in the U.S. Environmental Protection Agency's Clean Water Act section 303(d). The majority of streams in northwestern Mississippi are on the 303(d) list of water-quality limited...
Hydrogeology and simulation of ground-water flow near Mount Pleasant, South Carolina: Predevelopment, 2004, and predicted scenarios for 2030
Matthew D. Petkewich, Bruce G. Campbell
2007, Scientific Investigations Report 2007-5126
Heavy water use from the Cretaceous Middendorf aquifer in South Carolina has created a large, regional cone of depression in the potentiometric surface of the Middendorf aquifer in Charleston and Berkeley Counties, South Carolina. Water-level declines of up to 249 feet have been observed in wells over the past 125...
Chapter 8 Tool for monitoring hydrophilic contaminants in water: polar organic chemical integrative sampler (POCIS)
David A. Alvarez, James N. Huckins, Jimmie D. Petty, Tammy L. Jones-Lepp, Frank Stuer-Lauridsen, Dominic T. Getting, Jon P. Goddard, Anthony Gravell
2007, Comprehensive Analytical Chemistry (48) 171-197
The development of the polar organic chemical integrative sampler (POCIS) provides environmental scientists and policy makers a tool for assessing the presence and potential impacts of the hydrophilic component of these organic contaminants. The POCIS provides a means for determining the time-weighted average (TWA) concentrations of targeted chemicals that can...

Dycheia shergoldi, a new genus and species of Late Cambrian Multivalved Mollusc from Oklahoma, USA
J. Pojeta Jr., James R. Derby
2007, Memoirs of the Association of Australasian Palaeontologists (34) 489-497
A new mollusc from the Upper Cambrian Fort Sill Limestone of Oklahoma, U.S.A. is described. Dycheia shergoldi has at least two types of valves, but the total number of valves is unknown, because the species is known only from disarticulated specimens. The valves show various morphological similarities to Cambrian and...
Geophysical analysis of the Salmon Peak Formation near Amistad Reservoir Dam, Val Verde County, Texas, and Coahuila, Mexico, March 2006, to aid in piezometer placement
Gregory P. Stanton, Wade H. Kress, Andrew Teeple, Michael L. Greenslate, Allan K. Clark
2007, Scientific Investigations Report 2007-5143
Since 1992, numerous sinkholes have developed northwest of the Amistad Reservoir dam on the Rio Grande. Increases in the discharge of springs south of the dam, on the western side of the Rio Grande, in Coahuila, Mexico, have been documented. In 1995 the Mexico Section of the International Boundary and...
High-resolution topographic, bathymetric, and oceanographic data for the Pleasure Point area, Santa Cruz County, California: 2005-2007
Curt D. Storlazzi, Patrick L. Barnard, Brian D. Collins, David P. Finlayson, Nadine E. Golden, Gerry A. Hatcher, Robert E. Kayen, Peter Ruggiero
2007, Open-File Report 2007-1270
The County of Santa Cruz Department of Public Works and the County of Santa Cruz Redevelopment Agency requested the U.S. Geological Survey (USGS) Western Coastal and Marine Geology Team (WCMG) to provide baseline geologic and oceanographic information on the coast and inner shelf at Pleasure Point, Santa Cruz County, California....
Introduction to Regional Geology, Tectonics, and Metallogenesis of Northeast Asia
Leonid M. Parfenov, Gombosuren Badarch, Nikolai A. Berzin, Duk-Hwan Hwang, Alexander I. Khanchuk, Mikhail I. Kuzmin, Warren J. Nokleberg, Alexander O. Obolenskiy, Masatsugu Ogasawara, Andrei V. Prokopiev, Sergey M. Rodionov, Alexander P. Smelov, Hongquan Yan
2007, Open-File Report 2007-1183-A
Purpose This introduction presents an overview of the regional geology, tectonics, and metallogenesis of Northeast Asia. The major purposes are to provide a relatively short summary of these features for readers who are unfamiliar with Northeast Asia; a general scientific introduction for the succeeding chapters of this volume; and an overview...
Conceptual design of the Everglades Depth Estimation Network (EDEN) grid
John Jones, Susan D. Price
2007, Open-File Report 2007-1200
The Everglades Depth Estimation Network (EDEN) offers a consistent and documented dataset that can be used to guide large-scale field operations, to integrate hydrologic and ecological responses, and to support biological and ecological assessments that measure ecosystem responses to the Comprehensive Everglades Restoration Plan (Telis, 2006). Ground elevation data for...
A monthly water-balance model driven by a graphical user interface
Gregory J. McCabe, Steven L. Markstrom
2007, Open-File Report 2007-1088
This report describes a monthly water-balance model driven by a graphical user interface, referred to as the Thornthwaite monthly water-balance program. Computations of monthly water-balance components of the hydrologic cycle are made for a specified location. The program can be used as a research tool, an assessment tool, and a...
