Use of passive diffusion samplers for monitoring volatile organic compounds in ground water
Philip T. Harte, Michael J. Brayton, Wayne Ives
2000, Fact Sheet 088-00
Passive diffusion samplers have been tested at a number of sites where volatile organic compounds (VOC's) are the principal contaminants in ground water. Test results generally show good agreement between concentrations of VOC's in samples collected with diffusion samplers and concentrations in samples collected by purging the water from a...

Peter E. Church, Forest P. Lyford, Scott Clifford
2000, Open-File Report 2000-276
Volatile organic compounds are present in soils and ground water at the Centredale Manor Superfund Site in North Providence, Rhode Island. In September 1999, water-to-vapor diffusion samplers were placed in the bottom sediments of waterways adjacent to the site to identify possible contaminated ground-water discharge areas. The approximate12-acre site is...

2000, Icarus (146) 98-117
Lunar Transient Phenomena (LTP) have been reported for at least 450 years. The events range from bright flashes, to reddish or bluish glows, to obscurations. Gaseous spectra and photometric measurements of the events have been obtained. Several theories have been offered as explanations for LTP, including residual volcanic activity or...

Stephen J. Kalkhoff
2000, Iowa Groundwater Quarterly (11)
An integrated assessment of the water quality in streams and aquifers in the Wapsipinicon, Iowa, Cedar, and Skunk River basins was conducted in 1996 through 1998 as part of the Eastern Iowa Basins (EIWA) study unit of the U.S. Geological Survey's National Water-Quality Assessment Program (NAWQA). The EIWA study unit...
Transport, behavior, and fate of volatile organic compounds in streams
R. E. Rathbun
2000, Critical Reviews in Environmental Science and Technology (30) 129-295
Volatile organic compounds (VOCs) are compounds with chemical and physical properties that allow the compounds to move freely between the water and air phases of the environment. VOCs are widespread in the environment because of this mobility. Many VOCs have properties that make them suspected or known hazards to the...
Formation of submarine flat-topped volcanic cones in Hawai'i
D. Clague, James G. Moore, J.R. Reynolds
2000, Bulletin of Volcanology (62) 214-233
High-resolution bathymetric mapping has shown that submarine flat-topped volcanic cones, morphologically similar to ones on the deep sea floor and near mid-ocean ridges, are common on or near submarine rift zones of Kilauea, Kohala (or Mauna Kea), Mahukona, and Haleakala volcanoes. Four flat-topped cones on Kohala were explored and sampled...
Volcanism and ice interactions on Earth and Mars
Mary G. Chapman, Carlton C. Allen, Magnus T. Gudmundsson, Virginia C. Gulick, Sveinn P. Jakobsson, Baerbel K. Lucchitta, Ian P. Skilling, Richard B. Waitt
2000, Book chapter, Environmental effects on volcanic eruptions: From deep oceans to deep space
Volcano/ice interactions produce meltwater. Meltwater can enter the groundwater cycle and under the influence of hydrothermal systems, it can be later discharged to form channels and valleys or cycled upward to melt permafrost. Water or ice-saturated ground can erupt into phreatic craters when covered by lava. Violent mixing of meltwater...

2000, Ecosystems (3) 352-368
We asked whether 3–5 kg N y−1 atmospheric N deposition was sufficient to have influenced natural, otherwise undisturbed, terrestrial and aquatic ecosystems of the Colorado Front Range by comparing ecosystem processes and properties east and west of the Continental Divide. The eastern side receives elevated N deposition from urban, agricultural,...

As the planet's principal cold traps, the martian polar regions have accumulated extensive mantles of ice and dust that cover individual areas of ∼106 km2 and total as much as 3–4 km thick. From the scarcity of superposed craters on their surface, these layered deposits are thought to be comparatively young—preserving a...
The effect of residential development on ground-water quality near Detroit, Michigan
M.A. Thomas
2000, Journal of the American Water Resources Association (36) 1023-1038
Two water-quality studies were done on the outskirts of the Detroit metropolitan area to determine how recent residential development has affected ground-water quality. Pairs of monitor and domestic wells were sampled in areas where residential land use overlies glacial outwash deposits. Young, shallow waters had significantly higher median concentrations of...

T. J. Lopes, J. D. Fallon, T.L. Maluk
2000, Journal of Environmental Engineering (126) 769-773
Accurate mean concentrations of volatile organic compounds (VOCs) can easily and economically be obtained from a single VOC analysis by using proven methods of collecting representative, discrete water samples and compositing them with a gas-tight syringe. The technique can be used in conjunction with chemical analysis by a conventional laboratory,...
Bleached chondrules: Evidence for widespread aqueous processes on the parent asteroids of ordinary chondrites
J. N. Grossman, C. M. O’D. Alexander, Jingyuan Wang, A.J. Brearley
2000, Meteoritics and Planetary Science (35) 467-486
We present the first detailed study of a population of texturally distinct chondrules previously described by Kurat (1969), Christophe Michel-Lévy (1976), and Skinner et al. (1989) that are sharply depleted in alkalis and Al in their outer portions. These “bleached” chondrules, which are exclusively radial pyroxene and cryptocrystalline in texture, have porous...

2000, Book, Journal of Geochemical Exploration
Norris–Mammoth corridor is a complex subsidence structure that extends ∼40 km northward from the 0.6 Ma Yellowstone caldera, and contains many hydrothermal features with high fluid discharges totaling ∼1000 l/s. About 150–250 l/s of hydrothermal water, which attains boiling temperature at surface and 360°C at depth, discharge from the Norris...
Carbon dioxide from coal combustion: Variation with rank of US coal
J.C. Quick, D.C. Glick
2000, Fuel (79) 803-812
Carbon dioxide from combustion of US coal systematically varies with ASTM rank indices, allowing the amount of CO2 produced per net unit of energy to be predicted for individual coals. No single predictive equation is applicable to all coals. Accordingly, we provide one equation for coals above high volatile bituminous...
Intra- and inter-unit variation in fly ash petrography and mercury adsorption: Examples from a western Kentucky power station
J.C. Hower, R. B. Finkelman, R.F. Rathbone, J. Goodman
2000, Energy and Fuels (14) 212-216
Fly ash was collected from eight mechanical and 10 baghouse hoppers at each of the twin 150-MW wall-fired units in a western Kentucky power station. The fuel burned at that time was a blend of many low-sulfur, high-volatile bituminous Central Appalachian coals. The baghouse ash showed less variation between units...
