This national assessment of 55 volatile organic compounds (VOCs) in ground water gives emphasis to the occurrence of VOCs in aquifers that are used as an important supply of drinking water. In contrast to the monitoring of VOC contamination of ground water at point-source release sites, such as landfills and leaking...

Janet M. Carter, Stephen J. Grady, Gregory C. Delzer, Bart Koch, John S. Zogorski
2006, Journal - American Water Works Association (98) 91-104
Results from two national surveys indicate that the gasoline oxygenate methyl tertiary butyl ether (MTBE) is one of the most frequently detected volatile organic compounds in source waters used by community water systems in the United States. Three other ether oxygenates were detected infrequently but almost always co-occurred with MTBE....

2006, Journal of Geophysical Research E: Planets (111)
Rocks on the floor of Gusev crater are basalts of uniform composition and mineralogy. Olivine, the only mineral to have been identified or inferred from data by all instruments on the Spirit rover, is especially abundant in these rocks. These picritic basalts are similar in many respects to certain Martian...
Headward growth of chasmata by volatile outbursts, collapse, and drainage: Evidence from ganges chaos, Mars
J.A.P. Rodriguez, J. Kargel, D.A. Crown, L. F. Bleamaster III, K. L. Tanaka, V. Baker, H. Miyamoto, J. M. Dohm, S. Sasaki, G. Komatsu
2006, Geophysical Research Letters (33)
The nature and significance of collapse processes in Capri, Eos, and Ganges Chasmata remain poorly understood. Using Ganges Chasma as a type locality, these chasmata are interpreted to be the result of clustering and assimilation of multiple chaotic terrains, which primarily formed by localized depressurization-induced or thermally-triggered dissociation of buried...

Michelle L. Coombs, Thomas W. Sisson, Peter W. Lipman
2006, Journal of Volcanology and Geothermal Research (151) 19-49
Major-element and volatile (H2O, CO2, S) compositions of glasses from the submarine flanks of Kilauea Volcano record its growth from pre-shield into tholeiite shield-stage. Pillow lavas of mildly alkalic basalt at 2600–1900 mbsl on the upper slope of the south flank are an intermediate link...

The United States (U.S.) National Park Service has initiated research on the atmospheric deposition and fate of semi-volatile organic compounds in its alpine, sub-Arctic, and Arctic ecosystems in the Western U.S. Results for the analysis of pesticides in seasonal snowpack samples collected in spring 2003 from seven national parks are...
Nature and characteristics of the flows that carved the Simud and Tiu outflow channels, Mars
J.A.P. Rodriguez, K. L. Tanaka, H. Miyamoto, S. Sasaki
2006, Geophysical Research Letters (33)
Geomorphic and topographic relations of higher and lower levels of dissection within the Simud and Tiu Valles outflow channels on Mars reveal new insights into their formational histories. We find that the water floods that carved the higher channel floors were primarily sourced from Hydaspis Chaos. The floods apparently branched...
