Initial report of the IMAGES VIII/PAGE 127 gas hydrate and paleoclimate cruise on the RV Marion Dufresne in the Gulf of Mexico, 2-18 July 2002
William J. Winters, T.D. Lorenson, Charles K. Paull
2007, Open-File Report 2004-1358
The northern Gulf of Mexico contains many documented gas hydrate deposits near the sea floor. Although gas hydrate often is present in shallow subbottom sediment, the extent of hydrate occurrence deeper than 10 meters below sea floor in basins away from vents and other surface expressions is unknown. We obtained...
Studies on Disinfection By-Products and Drinking Water
Colleen E. Rostad
2007, Fact Sheet 2004-3032
Drinking water is disinfected with chemicals to remove pathogens, such as Giardia and Cryptosproridium, and prevent waterborne diseases such as cholera and typhoid. During disinfection, by-products are formed at trace concentrations. Because some of these by-products are suspected carcinogens, drinking water utilities must maintain the effectiveness of the disinfection process...
Geology and Mineral Resources of the East Mojave National Scenic Area, San Bernardino County, California
Ted G. Theodore, editor(s)
2007, Miscellaneous Field Studies Map 2414
From our evaluations that largely used model-based criteria, we conclude that much of the East Mojave National Scenic Area (EMNSA) contains significant indications of epigenetic mineralization of various types. Economically significant concentrations of many metals may possibly remain to be discovered in many parts of the EMNSA (see also Wetzel...
Geology and Mineral Resources of the East Mojave National Scenic Area, San Bernardino County, California
Ted G. Theodore, editor(s)
2007, Bulletin 2160
The rocks of the East Mojave National Scenic Area (EMNSA) record a history of dynamic geologic events that span more than 1,800 million years (m.y.). These geologic events contributed significantly to development of the spectacular vistas and panoramas present in the area today. The oldest rocks underlie much of the...
Exploring links between systematics and fisheries management
Jay R Stauffer, Patrick M. Kocovsky
2007, Transactions of the American Fisheries Society (136) 1122-1125
We argue that the sustainable management of fisheries resources depends on an understanding of the taxonomy and systematics of fish. Toward this end, it is necessary for fisheries managers to understand and apply the various species concepts that have been developed by taxonomists and evolutionary biologists and to decide, based...

Buffelgrass (Pennisetum ciliare) land conversion and productivity in the plains of Sonora, Mexico
Kim A. Franklin, Kelly Lyons, Pamela L. Nagler, Derrick Lampkin, Edward P. Glenn, Francisco Molina-Freaner, Therese Markow, Alfredo R Huete
2006, Biological Conservation (127) 62-71
Bufflelgrass (Pennisetum ciliare syn. Cenchrus ciliaris) is an African grass that has been widely introduced in subtropical arid regions of the world to improve rangelands for cattle production. However, it can have a negative effect on the diversity of native plant communities. Buffelgrass was introduced to Sonora, Mexico in the 1970s as...
Use of an ADCP to compute suspended-sediment discharge in the tidal Hudson River, New York
Gary R. Wall, Elizabeth A. Nystrom, Simon Litten
2006, Scientific Investigations Report 2006-5055
Acoustic Doppler current profilers (ADCPs) can provide data needed for computation of suspended-sediment discharge in complex river systems, such as tidal rivers, in which conventional methods of collecting time-series data on suspended-sediment concentration (SSC) and water discharge are not feasible. Although ADCPs are not designed to measure SSC, ADCP data...
