John O’Malley
2007, Open-File Report 2007-1186
The U.S. Geological Survey (USGS) ArcMap Sediment Classification tool is a custom toolbar that extends the Environmental Systems Research Institute, Inc. (ESRI) ArcGIS 9.2 Desktop application to aid in the analysis of seabed sediment classification. The tool uses as input either a point data layer with field attributes containing...
Geosoft eXecutables (GX's) Developed by the U.S. Geological Survey, Version 2.0, with Notes on GX Development from Fortran Code
Jeffrey D. Phillips
2007, Open-File Report 2007-1355
Introduction Geosoft executables (GX's) are custom software modules for use with the Geosoft Oasis montaj geophysical data processing system, which currently runs under the Microsoft Windows 2000 or XP operating systems. The U.S. Geological Survey (USGS) uses Oasis montaj primarily for the processing and display of airborne geophysical data. The ability...
Data from theodolite measurements of creep rates on San Francisco Bay region faults, California: 1979-2007
Forrest S. McFarland, James J. Lienkaemper, S. John Caskey, Karen Grove
2007, Open-File Report 2007-1367
Introduction Our purpose is to update with six additional years of data, our creep data archive on San Francisco Bay region active faults for use by the scientific research community. Earlier data (1979-2001) were reported in Galehouse (2002) and were analyzed and described in detail in a summary report (Galehouse and...
Water and sediment quality in the Yukon River and its tributaries between Atlin, British Columbia, Canada, and Eagle, Alaska, USA, 2004
Douglas R. Halm, Mark M. Dornblaser
2007, Open-File Report 2007-1197
The Yukon River basin is the fourth largest watershed in North America at 855,300 square kilometers (km2). Approximately 126,000 people live within the basin and depend on the Yukon River and its tributaries for drinking water, commerce, subsistence and recreational fish and game resources.Climate warming in the Arctic...
Chemical data for rock, sediment, biological, precipitate, and water samples from abandoned copper mines in Prince William Sound, Alaska
Randolph A. Koski, LeeAnn Munk
2007, Open-File Report 2007-1359
Introduction In the early 20th century, approximately 6 million metric tons of copper ore were mined from numerous deposits located along the shorelines of fjords and islands in Prince William Sound, Alaska. At the Beatson, Ellamar, and Threeman mine sites (fig. 1), rocks containing Fe, Cu, Zn, and Pb sulfide minerals...
Quality of Water in Selected Wells, Harrison County, Mississippi, 1997-2005
David E. Burt Jr., Heather L. Welch
2007, Open-File Report 2007-1287
The U.S. Geological Survey collects, on a systematic basis, data needed to determine and evaluate the ground-water resources of Harrison County, Mississippi. Water samples were collected from 1997 to 2005 at selected wells screened in the Citronelle, Graham Ferry, Pascagoula, Hattiesburg, and Catahoula Sandstone aquifers and were analyzed for field...
Hawaiian Volcano Observatory 1956 Quarterly Administrative Reports
Jennifer S. Nakata
2007, Open-File Report 2007-1316
The Hawaiian Volcano Observatory Summaries have been published in the current format since 1956. The Quarterly Summaries (1956 through 1973) and the Annual Summaries (1974 through 1985) were originally published as Administrative Reports. These reports have been compiled and published as U.S. Geological Survey Open-File Reports. The quarterly reports have...
Streamflow and Sediment Data Collected to Determine the Effects of Low Summer Steady Flows and Habitat Maintenance Flows in 2000 on the Colorado River between Lees Ferry and Bright Angel Creek, Arizona
John C. Schmidt, David J. Topping, David M. Rubin, Joseph E. Hazel Jr., Matt Kaplinski, Stephen M. Wiele, Sara A. Goeking
2007, Open-File Report 2007-1268
The low summer steady flows (LSSF) experiment of 2000 further demonstrated that spike flows released from Glen Canyon Dam redistribute sand from the channel bed and lower elevation parts of eddy sandbars to channel-margin deposits and the higher elevation parts of eddy sandbars. Unfortunately, summer 2000 was a period of...
Review of Selected Documents Related to Flooding at City of Salisbury Facilities on the Yadkin River Upstream from High Rock Dam, North Carolina, September 2007
Jerad D. Bales
2007, Open-File Report 2007-1314
This report documents a review of the hydraulic and sediment-transport models developed by the City of Salisbury, Alcoa Power Generating, Inc., and the Federal Energy Regulatory Commission to address issues of flooding and sedimentation in the vicinity of Salisbury's water-supply intake 19.4 miles upstream from High Rock Dam. The objective...
Evaluation of Potash Grade with Gamma-ray Logs
Philip H. Nelson
2007, Open-File Report 2007-1292
Potassium is an emitter of gamma-ray radiation, consequently deposits of potash can be detected and evaluated using gamma-ray logs. A method originally designed to evaluate uranium deposits in boreholes can also be applied to potash deposits. The method equates the depth-integral of a gamma-ray log to the grade-thickness product of...

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....
