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...

Utilization of natural and supplemental biofuels for harvesting energy from marine sediments

Creator:: Nielsen, Mark E.
Abstract:: A benthic microbial fuel cell (BMFC) is an electrochemical device that generates current from the redox gradient at the sediment-water interface. Early prototypes had anodes buried in anoxic sediments and cathodes in overlying water. The BMFCs described in this dissertation are based on a chamber design that enables the use...

Geochemical cycling in a Pacific Northwest estuary (Tillamook Bay, Oregon, USA)

Creator:: Colbert, Debbie L.
Abstract:: This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...

Dynamics of organic matter production and degradation during coastal diatom blooms

Creator:: Wetz, Michael S.
Abstract:: Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...

Inner-shelf circulation off the central Oregon Coast

Creator:: Kirincich, Anthony R.
Abstract:: Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...
