Hydrothermal alteration of sedimentary organic matter in Guaymas Basin, Gulf of California

Creator:: Kawka, Orest Eduard Mykola
Resource Type:: Dissertation

The influence of early diagenesis on trace element and molybdenum isotope geochemistry

Creator:: Poulson, Rebecca L.
Abstract:: This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environments investigated, providing an essential geochemical context for interpreting the observed behavior of Mo in these settings. Chapter...

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....

Polar organic compounds as tracers of environmental processes

Creator:: Medeiros, Patricia Matheus de
Abstract:: Sources of polar/water-soluble organic compounds conjunctly with apolar biomarkers were characterized in natural organic matter. This multi-biomarker approach was accomplished by a simple analytical method consisting of extraction with dichloromethane:methanol (2:1, v/v), silylation and analysis by gaschromatography- mass spectrometry (GC-MS). Polar and apolar biomarkers, derived mainly from higher plants and...

Characteristics of soil organic matter in two forest soils

Creator:: Crow, Susan E.
Abstract:: Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

Techniques of solvent extraction of organic material from natural waters

Creator:: Cronin, John Thomas, 1935-
Abstract:: Manual and automatic solvent extraction techniques were used to concentrate organic material from natural waters. Field and laboratory extractions were compared to determine the most probable method and best solvents for efficient concentration of organic material from estuarine and sea waters. The large scale extraction processes utilizing extractors made from...

Hydrologic and Land Cover Effects on Sources and Fate of In-Stream Fluorescent Dissolved Organic Matter

Creator:: Lee, Baek Soo P.
Abstract:: Dissolved organic matter (DOM) is a critical component of the carbon cycle linking terrestrial and aquatic ecosystems. Although many factors influence DOM fluxes and quality in rivers, controls on DOM compositions in catchments of the western U.S. are poorly understood. UV and fluorescent spectroscopy is a simpler, faster, and less...

Semi-volatile organic compounds as molecular markers for atmospheric and ecosystem transport

Creator:: Genualdi, Susan A.
Abstract:: The use of semi-volatile organic compounds (SOCs) as molecular markers to identify the contributions of regional and long-range atmospheric transport, as well as current and historic sources, and contaminant deposition in remote ecosystems of the Western U.S. was investigated. Trans-Pacific air masses influenced by Siberian biomass burning events had elevated...
