Characterization of the glycoprotein of infectious hematopoietic necrosis virus using neutralizing monoclonal antibodies
Chienjin Huang, Maw-Sheng Chien, Marsha Landolt, James Winton
1994, Diseases of Aquatic Organisms (18) 29-35
To study the antigenic nature of the glycoprotein (G protein) of infectious hematopoietic necrosis virus (IHNV), 31 neutralizing monoclonal antibodies (MAbs) were produced against a reference isolate of the virus. The MAbs were compared using a neutralization assay, an enzyme-linked immunosorbent assay (ELISA), and by immunoblotting of the G protein...
Coupling of volatile transport and internal heat flow on Triton
Robert H. Brown, Randolph L. Kirk
1994, Journal of Geophysical Research E: Planets (99) 1965-1981
Recently Brown et al. (1991) showed that Triton's internal heat source could amount to 5–20% of the absorbed insolation on Triton, thus significantly affecting volatile transport and atmospheric pressure. Subsequently, Kirk and Brown (1991a) used simple analytical models of the effect of internal heat on the distribution of volatiles on...
500,000-year stable carbon isotopic record from Devils Hole, Nevada
T.B. Coplen, I.J. Winograd, J.M. Landwehr, A.C. Riggs
1994, Science (263) 361-365
The record of carbon-13 (δ13C) variations in DH-11 vein calcite core from Devils Hole, Nevada, shows four prominent minima near glacial terminations (glacial-interglacial transitions) V to II. The δ13C time series is inversely correlated with the DH-11 oxygen isotope ratio time series and leads it by as much as 7000...
Tamarisk control on public lands in the desert of southern California: two case studies
1994, Book, Proceedings of the forty-sixth annual California Weed Science Society
As a land manager, the Federal Government faces enormous challenges from exotic pest invasions and associated changes to the structure and stability of native ecosystems (Bureau of Land Management, 1988). On public lands administered by the Bureau of Land Management (BLM) alone, it is estimated that almost three million hectares...
Hydrology and quality of ground water in northern Thurston County, Washington
N. P. Dion, G. L. Turney, M. A. Jones
1994, Water-Resources Investigations Report 92-4109
Northern Thurston County is underlain by as much as 1,000 feet of unconsolidated deposits of Pleistocene Age, that are of both glacial and nonglacial origin. Interpretation of 17 geologic sections led to the delineation of 7 major geohydrologic units, 3 of which constitute aquifers in the area. Precipitation ranges from...
Varve calibrated records of carbonate and organic carbon accumulation over the last 2000 years in the Black Sea
Michael A. Arthur, Walter E. Dean, E.D. Neff, B.J. Hay, J. King, Glenn A. Jones
1994, Global Biogeochemical Cycles (8) 195-217
Sedimentologic and geochemical studies of box and gravity cores recovered from the Black Sea during the first leg of a multileg international Black Sea expedition in 1988 allow reconstruction of the basinwide Holocene environmental history of the Black Sea. In the deeper parts of the basin, box cores typically recovered...

High-precision 40Ar/39Ar age spectrum dating of sanidine from the Middle Pennsylvanian Fire Clay tonstein of the Appalachian basin
Michael J. Kunk, Charles L. Rice
1994, GSA Special Papers (294) 105-112
40Ar/39Ar plateau age spectra of seven sanidine samples from the Fire Clay tonstein (Middle Pennsylvanian), collected along a 300-km traverse in the Appalachian basin, range from 310.3 to 311.4 Ma. All plateau ages agree, within the limits of analytical precision, with their respective total gas ages. This agreement, together with...
40Ar/39Ar chronology and volcanology of silicic volcanism in the Davis Mountains, Trans-Pecos Texas
Christopher D. Henry, Michael J. Kunk, W. C. McIntosh
1994, GSA Bulletin (106) 1359-1376
Field studies and 40Ar/39Ar dating reveal that silicic volcanism in the Davis Mountains part of the Trans-Pecos Texas volcanic field occurred in six episodes at 0.3 m.y. intervals between 36.8 and 35.3 Ma. Additionally, two groups of silicic intrusions were emplaced at 34.6 and 32.8 Ma. This episodicity is similar to...
40Ar 39Ar age constraints on neogene sedimentary beds, Upper Ramparts, half-way Pillar and Canyon village sites, Porcupine river, east-central Alaska
Michael J. Kunk, H. Rieck, T. D. Fouch, L. David Carter
1994, Quaternary International (22-23) 31-42
40Ar/39Ar ages of volcanic rocks are used to provide numerical constraints on the age of middle and upper Miocene sedimentary strata collected along the Porcupine River. Intercalated sedimentary rocks north of latitude 67°10′N in the Porcupine terrane of east-central Alaska contain a rich record of plant fossils. The fossils are valuable...
The Pennsylvanian Fire Clay tonstein of the Appalachian basin—Its distribution, biostratigraphy, and mineralogy
C. L. Rice, Harvey E. Belkin, T.W. Henry, R. E. Zartman, Michael J. Kunk
1994, GSA Special Papers (294) 87-104
The Middle Pennsylvanian Fire Clay tonstein, mostly kaolinite and minor accessory minerals, is an altered and lithified volcanic ash preserved as a thin, isochronous layer associated with the Fire Clay coal bed. Seven samples of the tonstein, taken along a 300-km traverse of the central Appalachian basin, contain cogenetic phenocrysts...
Fate and pathways of injection-well effluent in the Florida Keys
Eugene A. Shinn, Ronald S. Reese, Christopher D. Reich
1994, Open-File Report 94-276
Twenty-four wells (21 locations) were core drilled into the limestone beneath the Keys, reef tract, and outer reefs to determine if sewage effluents injected in Class V wells onshore are reaching offshore reef areas via underground flow. These wells were fitted with PVC casings and well screens and were...
Velocities of the Smith Glacier Ice Tongue and Dotson Ice Shelf, Walgreen Coast, Marie Byrd Land, West Antarctica
Baerbel K. Lucchitta, Kevin F. Mullins, C. E. Smith, Jane G. Ferrigno
1994, Annals of Glaciology (20) 101-109
Velocity measurements were made for two time intervals on the Smith Glacier ice tongue (1973–88 and 1988–90) and three on the Dotson Ice Shelf (1972–88, 1973–88 and 1988–90). The Smith Glacier ice tongue velocities for the two intervals are similar near the grounding line but show a progressive increase toward...
Modeling fluid flow and heat transfer at Basin and Range faults: preliminary results for Leach hot springs, Nevada

1994, Book, Computers in mineral industry
Overcoming future difficulties in searching for ore deposits deeper in the earth's crust will require closer attention to the collection and analysis of more diverse types of data and to more efficient use of current computer technologies. Computer technologies of greatest interest include methods of storage and retrieval of resource...
Nutrient additions by waterfowl to lakes and reservoirs: predicting their effects on productivity and water quality
Bruce A. Manny, W.C. Johnson, R.G. Wetzel
1994, Hydrobiologia (279/280) 121-132
Lakes and reservoirs provide water for human needs and habitat for aquatic birds. Managers of such waters may ask whether nutrients added by waterfowl degrade water quality. For lakes and reservoirs where primary productivity is limited by phosphorus (P), we developed a procedure that integrates annual P loads...

Bison in the greater Yellowstone
Mary Meagher
1994, Report
In the Greater Yellowstone Area, free-ranging bison occur in Jackson Hole, Wyoming, and Yellowstone National Park. The Yellowstone population is discussed, with emphasis on changes in numbers from approximately 400 in 1968 to about 3500 now. Major influences for change initially were natural; more recently the winter road...
Charadrius montanus: Montane, grassland, or bare-ground plover?
Fritz L. Knopf, B. Miller
1994, The Auk (111) 504-506
The Mountain Plover (Charadrius montanus) is an aridland member of the Charadriidae. This plover is generally considered an associate of the North American shortgrass prairie, which is dominated by blue grama (Bouteloua gracilis) and buffalo grass (Buchloe dactyloides; Graul 1975). The species breeds at many locations across the western Great...
