Assessment of diffusive isotopic fractionation in polar firn, and application to ice core trace gas records

Creator:: Buizert, Christo, Sowers, Todd, and Blunier, Thomas
Abstract:: During rapid variations of the atmospheric mixing ratio of a trace gas, diffusive transport in the porous firn layer atop ice sheets and glaciers alters the isotopic composition of that gas relative to the overlying atmosphere. Records of past atmospheric trace gas isotopic composition from ice cores and firn need...

Indoor/outdoor atmospheric trace element abundances

Creator:: Cheung, Isabella Shiu Wing
Abstract:: The atmospheric trace element abundances associated with "indoor" and '"outdoor" air particulate have been measured for university chemistry laboratories, typical homes, modern office buildings, hospital and automobile repair garages in a rural setting (Corvallis, Oregon) and modern office buildings in an urban setting (Portland, Oregon). Samples of atmospheric particulate matter...

Glass capillary gas chromatographic analysis for trace amounts of cyclopropenoid fatty acids

Creator:: Ryan, Daberath
Abstract:: Dietary cyclopropenoid fatty acids (CPFA) have long been known to cause pronounced physiological disorders in both farm and laboratory animals. Past work has shown CPFA to be a powerful promoter of carcinogenesis in trout, rats and mice. Sterculic and malvalic acids (CPFA's) are found in seed lipids of plants from...

Flame ionization detection of hydrocyanic acid ; Analysis of trace aqueous solutions

Creator:: Claeys, Robert Raymond
Abstract:: A gas chromatographic procedure was developed for the determination of nanogram quantities of hydrocyanic acid using a flame ionization detector. Excellent chromatograms were obtained on a porous polyaromatic polymer column (Porapak Q) at 60°C. The procedure was employed for the analysis of HCN in aqueous cyanide solutions. Solutions as low...

Trace metals in phytoplankton from an area of coastal upwelling

Creator:: Pequegnat, John Eugene
Abstract:: Short-term changes in the distribution, surface to 10 meters, of phytoplankton-associated trace metals (Fe, Mn, Cr, Zn, Co, Ni, and Cu) were studied in the near-shore waters off Humboldt Bay, California, through the summer of 1971. The depth distribution of phytoplankton-associated trace metals was related to local hydrography. During periods...

Legacy of Hydrate Ridge: an illustrated account

Creator:: Suess, Erwin
Abstract:: Hydrate Ridge has the distinction of hosting the first documented subduction-driven cold seep system that supports chemosynthetic life by Anaerobic Oxidation of Methane as well as the most widely researched methane hydrate setting at any active continental margin. Today this site is a vital node of Northeast Pacific regional long-term...

Development of trace enrichment techniques for trace metals in natural waters using high pressure liquid chromatography

Creator:: Ambrose, Arthur Sigurd
Abstract:: An on-line trace enrichment (TE) system, based on high pressure liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has been developed for trace metal analysis. The sample is pumped through a column filled with a cation exchange resin which traps metal ions. The ions are subsequently stripped from the column...
