The Geophysical Research and Development Project supported the development of new and existing geophysical techniques for addressing critical geological problems. Research conducted under this project included development of needed geophysical methods and software, development of new geophysical instrumentation, and applications of geophysical techniques to frontier areas of geology.
Science Issue and Relevance
Many projects within the U.S. Geological Survey (USGS) use geophysics as a tool for studying buried or concealed geologic features. The availability of modern geophysical instrumentation and data interpretation software is often critical to the success of these projects. However, most projects using geophysics lack the resources to evaluate, purchase, maintain, and provide training for geophysical equipment and software. In addition, the development of any new geophysical technology is a risky, long-term activity, that is well beyond the scope of most individual projects.
Methods to Address Issue
The Geophysical Research and Development Project ran from 1996 to 2012 and provided the geophysical equipment and software tools USGS projects needed. The Project strived to anticipate and develop new geophysical technologies that the Survey would need within the next several years and supported the development of new and existing geophysical techniques to address critical geological problems.
Research conducted under this project includes development of needed geophysical methods and software, development of new geophysical instrumentation, and applications of geophysical techniques to frontier areas of geology.
Technologies supported and developed fell within the general categories of geoelectrical methods, potential-field methods, and gamma-ray methods. These methods permitted geophysical investigations at a broad range of scales from national and regional scales to local and site characterization scales, and at a range of depths from a few centimeters to tens of kilometers.
Supported geophysical methods include potential-field methods (gravity and magnetics), electrical methods (DC resistivity, induced polarization, and self-potential), electromagnetic methods (magnetotellurics (MT), ground penetrating radar (GPR), directional borehole radar, time-domain EM, and frequency-domain EM), shallow seismic methods (reflection, refraction, and surface-to-borehole), and gamma-ray geophysics.

Filter Total Items: 84pick_xwell, a program for interactive picking of crosswell seismic and radar data
Program 'pick_xwell' is used to interactively pick travel times in crosswell seismic and radar data. In addition, the traces and the travel times can be plotted on the computer screen or printed to a file in postscript format. The program is written in the IDL programming language, and it is executed, in command-line mode, within the IDL program. The IDL program must be run from an X-window tU.S. Geological Survey Program on the South Florida Ecosystem; proceedings of South Florida Restoration Science Forum, May 17-19, 1999, Boca Raton, Florida
The purpose of the forum is to highlight the powerful connection between science and management decisions in restoration efforts. The public's investment in science is paying off in support of better management decisions and restoration of imperiled south Florida Ecosystems, including the internationally recognized, globally significant Everglades. The forum affords a unique opportunity for electeAbstracts of the 11th Annual U.S. Geological Survey, Central Region, 1999 Poster Review; Collected Abstracts of Selected Poster Papers Presented at Scientific Meetings
In 1999, the U.S. Geological Survey Central Region had a poster review where USGS scientists showcased posters that had been presented at scientific meetings. This report contains abstracts for selected posters that were presented at this review. Science topics were from several USGS teams with a broad range of topics.Contributions to the gold metallogeny of northern Nevada
Nevada is one of the Earth's premier gold producing regions, accounting for approximately 64 percent of the U.S and nine percent of the world total. The impact of these mines on nearby local economies and on our national balance of payments is profound, and will continue well into the next century. Of principal importance in this region are giant sedimentary-rock-hosted (Carlin-type) deposits. TheGround-water contamination by crude oil: Section B in <i>U.S. Geological Survey Toxic Substances Hydrology Program: Proceedings of the technical meeting, Charleston, South Carolina, March 8-12, 1999: Volume 3 (Part C)</i>
Ground water contamination by crude oil, and other petroleum-based liquids, is a widespread problem. An average of 83 crude-oil spills occurred per year during 1994-96 in the United States, each spilling an average of about 50,000 barrels of crude oil (U.S. Office of Pipeline Safety, electronic commun., 1997).

In anticipation of the need for scientific support for policy decisions and in light of the decade-old perspective of a previous assessment, the USGS has completed a reassessment of the petroleum potential of the ANWR 1002 area. This was a comprehensive study by a team of USGS scientists in collaboration on technical issues (but not the assessment) with colleagues in other agencies and universitie
