Proposed expansion of the City of Albuquerque/U.S. Geological Survey ground-water-level monitoring network for the middle Rio Grande Basin, New Mexico
L. M. Bexfield
1998, Open-File Report 97-787
The Middle Rio Grande Basin in central New Mexico, extending from Cochiti Lake on the north to San Acacia on the south, covers an area of about 3,060 square miles. Ground-water withdrawals in the basin are concentrated in and around the city of Albuquerque. Because of rapid increases in population...

Bruce R. Johnson, Pamela D. Derkey
1998, Open-File Report 98-115
Geologic data from the geologic map of the Spokane 1:100,000-scale quadrangle compiled by Joseph (1990) were entered into a geographic information system (GIS) as part of a larger effort to create regional digital geology for the Pacific Northwest. The map area is located in eastern Washington and extends across the...
Generic names of northern and southern fur seals (Mammalia: Otariidae)
Alfred L. Gardner, C. Brian Robbins
1998, Marine Mammal Science (14) 544-551
We have resolved a nomenclatural problem discovered during research on the northern fur seal that concerns the correct generic name for this taxon and for fur seals of the Southern Hemisphere. The unfortunate practice by some 19th-century authors to use names in their Latinized form but to date them from...

Data include temperature, pH, conductivity, dissolved oxygen, alkalinity, flow, and total acid soluble and dissolved (<0.45 \im)...
Geologic framework and hydrogeologic characteristics of the outcrops of the Edwards and Trinity aquifers, Medina Lake area, Texas
Ted A. Small, Rebecca B. Lambert
1998, Water-Resources Investigations Report 97-4290
The hydrogeologic subdivisions of the Edwards aquifer outcrop in the Medina Lake area in Medina and Bandera Counties generally are porous and permeable. The most porous and permeable appear to be hydrogeologic subdivision VI, the Kirschberg evaporite member of the Kainer Formation; and hydrogeologic subdivision III, the leached and collapsed...
Fuel bed characteristics of Sierra Nevada conifers
J. W. van Wagtendonk, J.M. Benedict, W.M. Sydoriak
1998, Western Journal of Applied Forestry (13) 73-84
A study of fuels in Sierra Nevada conifer forests showed that fuel bed depth and fuel bed weight significantly varied by tree species and developmental stage of the overstory. Specific values for depth and weight of woody, litter, and duff fuels are reported. There was a significant positive relationship between...
Tag retention, growth, and survival of red swamp crayfish Procambarus clarkii marked with coded wire tags
J. Jeffery Isely, A.G. Eversole
1998, Transactions of the American Fisheries Society (127) 658-660
Juvenile red swamp crayfish (or crawfish), Procambarus clarkii (20–41 mm in total length) were collected from a crayfish culture pond by dipnetting and tagged with sequentially numbered, standard length, binary‐coded wire tags. Four replicates of 50 crayfish were impaled perpendicular to the long axis of the abdomen with a...

A strategy for assessing potential future changes in climate, hydrology, and vegetation in the Western United States
Robert Stephen Thompson, Steven W. Hostetler, Patrick J. Bartlein, Katherine H. Anderson
1998, Circular 1153
Historical and geological data indicate that significant changes can occur in the Earth's climate on time scales ranging from years to millennia. In addition to natural climatic change, climatic changes may occur in the near future due to increased concentrations of carbon dioxide and other trace gases in the atmosphere...
Characterization of hydrogeologic units using matrix properties, Yucca Mountain, Nevada
L. E. Flint
1998, Water-Resources Investigations Report 97-4243
Determination of the suitability of Yucca Mountain, in southern Nevada, as a geologic repository for high-level radioactive waste requires the use of numerical flow and transport models. Input for these models includes parameters that describe hydrologic properties and the initial and boundary conditions for all rock materials within the unsaturated...
Assessment of the hydraulic connection between ground water and the Peace River, west-central Florida
B. R. Lewelling, A. B. Tihansky, J. L. Kindinger
1998, Water-Resources Investigations Report 97-4211
The hydraulic connection between the Peace River and the underlying aquifers along the length of the Peace River from Bartow to Arcadia was assessed to evaluate flow exchanges between these hydrologic systems. Methods included an evaluation of hydrologic and geologic records and seismic-reflection profiles, seepage investigations, and thermal infrared imagery...
Modeling of flood-deposited sand distributions in a reach of the Colorado River below the Little Colorado River, Grand Canyon, Arizona
S.M. Wiele
1998, Water-Resources Investigations Report 97-4168
A release from Glen Canyon Dam during March-April 1996 was designed to test the effectiveness with which the riparian environment could be renewed with discharges greatly in excess of the normal powerplant-restricted maximum. Of primary concern was the rebuilding of sand deposits along the channel sides that are important to...

International strategic mineral issues summary report– Tungsten
Antony B. T. Werner, W. David Sinclair, Earle B. Amey
1998, Circular 930-O
Scheelite and wolframite are the principal minerals currently mined for tungsten. Both occur in hard-rock deposits; wolframite is also recovered from placer deposits. Most current mine production of tungsten is from vein/stockwork, skarn, porphyry, and strata-bound deposits. Minor amounts are produced from disseminated, pegmatite, breccia, and placer deposits. Most tungsten is...
