Low molecular weight organic acids in forest soils

Creator:: Hayden, John
Abstract:: Two studies concerning low molecular weight organic acids in soils were conducted. In the first study, anion exclusion chromatography was used to separate and identify 12 common organic acids, and the accuracy, precision and detection limits of the method were determined. The method was found to be sensitive and accurate...

The major and minor element geochemistry of Lake Baikal

Creator:: Falkner, Kelly, Measures, Chris I., Herbelin, Sarah E., Edmond, John M., and Weiss, Ray F.
Abstract:: A comprehensive, joint Soviet-American study of the chemistry of Lake Baikal, the world’s deepest (1,632 m) lake, was carried out in July 1988. In this paper, we report the major, minor, and preliminary trace element concentrations for three profiles obtained at or near the deepest and central part of the...

Application of biomarker compounds as tracers for sources and fates of natural and anthropogenic organic matter in the environment

Creator:: Oros, Daniel R.
Abstract:: Determination of the source and fate of natural (higher plant lipids, marine lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived hydrocarbons and oxygenated compounds in the environment was accomplished using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) to characterize or identify molecular biomarkers to be utilized as tracers....

Geochemical characteristics of iron-manganese nodules in seasonally-saturated soils of the Willamette Valley, Oregon

Creator:: Seter, Lisa M.
Abstract:: This study was initiated to characterize the distribution of Fe-Mn nodules and to elucidate trends of Fe, Mn, and P relative to the intensity of the annual cycles of reduction and oxidation. Nodules were enriched in Fe, Mn, and P relative to the soil matrix making them an integral part...

Geochemical observations on Hydrate Ridge, Cascadia Margin : July 1999

Creator:: Torres, Marta E., Bohrmann, Gerhard, Brown, Kevin, deAngelis, Marie, Hammond, Douglas, Klinkhammer, Gary, McManus, James, Suess, Erwin, and Trehu, Anne
Abstract:: Geophysical and biogeochemical processes associated with fluid venting from active and passive continental margins will receive significant scientific and economic attention into the next century and are of major societal relevance. An important unknown among these interrelated processes is the role played by methane gas hydrates, at and below the...

Dissolved organic carbon in interstitial waters from sediments of Middle Valley, leg 139

Creator:: Ran, Baiyun and Simoneit, Bernd R. T.
Abstract:: High-temperature combustion oxidation measurements of nonvolatile dissolved organic carbon (DOC) have been determined for pore waters from sediments of Middle Valley, Ocean Drilling Program Leg 139, as well as for overlying and near-bottom seawater. The DOC values in the interstitial waters are generally greater than those in the overlying water...
