Scientists at the U.S. Geological Survey have expanded applications of the Chim electrode, technology used to perform partial geochemical extractions from soils. Recent applications of the the improved electrode technology show that geochemical extraction efficiencies can be improved by 2 orders of magnitude or better to about 30%....

The Devils Lake Basin is a 3,810-square-mile (mi2) closed basin (fig. 1) in the Red River of the North Basin. About 3,320 mi2 of the total 3,810 mi2 is tributary to Devils Lake; the remainder is tributary to Stump Lake.Since glaciation, the lake level of Devils Lake has fluctuated from about 1,457 feet...

The Devils Lake Basin is a 3,810-square-mile (mi2) closed basin (fig. 1) in the Red River of the North Basin.  The basin is contributing only when the level of Devils Lake is greater than 1,459 feet (ft) above sea level (asl). About 3,320 mi2<span...

Digital line graph (DLG) data are digital representations of cartographic information. DLG?s of map features are digital vectors converted from maps and related sources. The U.S. Geological Survey (USGS) DLG data are classified as large, intermediate, and small scale....

Many people want maps that show an area of the United States as it existed many years ago. These are called historical maps, and there are two types. The most common type consists of special maps prepared by commercial firms to show such historical features as battle-fields, military routes, or the...

Polychlorinated Biphenyls (PCBs) in the Great Lakes Despite being banned since the 1970's, polychlorinated biphenyls (PCBs) continue to pose a threat to the environment because of their persistence and toxicity to organisms ranging from minute algae to fish, waterfowl, and human beings. PCBs, a set of 209 related chlorinated organic...

A new seismic source generator has been invented at the U. S. Geological Survey. Using kinetic energy stored by a flywheel, the truck-mounted source transfers this energy, by impulses, into the ground. Both longitudinal (P) and shear (S) waves can be generated, the latter in 12 directions, without moving the vehicle....

As a research and information laboratory of the Federal government, the U.S. Geological Survey (USGS) is committed to making its developments readily available to customers within the private sector. The USGS is the Nation's premier earth science agency, providing unique scientific data and technology in the areas of natural hazards, environment, resources, and information. Often USGS research and information activities...

The following are USGS research projects offering an opportunity for Cooperative Research and Development Agreement (CRADA) partnerships. A CRADA is an agreement between one or more Federal agencies and one or more non-Federal agencies to work together in research or developmental activities. CRADAs permit both partners to share information in...

The following is a list of selected publications about major U.S. Geological Survey (USGS) activities, products, and services....

At present (1996), all drinking water for Albuquerque residents comes from ground-water reserves. The Albuquerque area is the largest population center in the State and the largest consumer of ground water. Recent reports concerning the water resources of the Albuquerque area suggest that the Albuquerque Basin may soon face serious water-availability...

The U.S. Geological Survey (USGS) publishes land characteristics data on CD-ROM. The following lists the types of products and their contents and specifications. The discs cost $32 each, plus a $5.00 handling fee per order mailed....

Scientists at the U.S. Geological Survey have developed a computer-based temperature control and video overlay system for use with the diamond anvil cell. The diamond-anvil cell (DAC) is a means for subjecting samples to very high pressures in laboratory experiments. For example, pressures to 100 kilobars can be achieved using the device. In addition, the DAC can subject...

Results of water-resources data-collection programs and interpretive hydrologic studies conducted by the U.S. Geological Survey (USGS) are published in reports and are made available to universities, State and local agencies, other Federal agencies, and the public. The following is a list of selected USGS reports on water resources in Mississippi...
