Measurement of the apparent dissociation constants of carbonic acid in seawater at atmospheric pressure

Creator:: Mehrbach, Carl
Abstract:: The apparent dissociation constants of carbonic acid were determined as functions of temperature and salinity in seawater at atmospheric pressure. There is fair agreement between my values of K'₁ and those of Buch et al. (1932), Lyman (1956), and Hansson (1971). My values, on the average, are 6.7% lower than...

Understanding the anodic mechanism of a seafloor fuel cell

Creator:: Ryckelynck, Natacha
Abstract:: Anoxic sediment overlain by oxic seawater establishes a voltage gradient on the order of 0.7-0.8V across the sediment-water interface. This study follows Reimers et al. (2001) and Tender et al. (2002) who reported the development of a seafloor fuel cell to harvest electrical energy from this potential difference. Prototype fuel...

A microcomputer software package for simulation of non-ideal aqueous electrolyte systems at equilibrium

Creator:: Sinquefield, Scott A.
Abstract:: The non-ideal aqueous electrolyte simulator (NAELS) is composed of three major parts: a Newton-Raphson non-linear optimization program written by Weare, et al (1987); an activity coefficient subroutine for non-ideal electrolyte systems based on Pitzer's model; and an extensive, user expandable database. It is robust, stable, and requires neither thermodynamic data...

An examination of the form and variability of manganese oxide in Columbia River suspended material

Creator:: Covert, Paul Allister
Abstract:: Suspended particulate matter (SPM) in the Columbia River is a mixture of particles of several origins having varying physical and biogeochemical properties. The relative abundances of these freshwater particles changes with season and apparently also with tide. Prior investigation has quantified seasonal variation of organic material in both the Columbia...

U(VI) transport in subsurface materials: is two-site, one-species modeling sufficient?

Creator:: Harrington, Stephanie J.
Abstract:: Uranium adsorption to Hanford sediment was studied for various pH, total inorganic carbon concentrations, and total U(VI) concentrations. Both batch and transport studies were done in an attempt to understand the adsorptive trend of U(VI) on Hanford sediment, and the changes in adsorption as both pH and total inorganic carbon...

The provenance and trace element signatures of MORB anorthitic plagioclase

Creator:: Burleigh, Andrew W.
Abstract:: In an attempt to understand the phase equilibria and petrogenesis of MORB anorthitic plagioclase, Cr-spinel commonly hosted within anorthitic plagioclase has been investigated petrographically and compositionally. Based on spinel-anorthite relationships from three samples of plagioclase ultra-phyric basalt (PUB; Southeast Indian Ridge, Axial Seamount and West Valley Segment, Juan de Fuca...

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...

Reactive transport modeling in a discrete fracture : applications to the formation of sericitic hydrothermal alteration at Butte, Montana

Creator:: Geiger, Sebastian
Abstract:: A model for the spatial and temporal evolution of the gray sericitic (GS) and sericite with remnant biotite (SBr) hydrothermal alteration selvages within the Butte Quartz Monzonite (BQM) of the porphyry copper deposit at Butte, Montana, is presented. The model provides a mathematical description for the location and advance of...

Petrology and geochemistry of the Emigrant Pass volcanics, Nevada : implications for a magmatic-hydrothermal origin of the Carlin gold deposits

Creator:: Johnson, Curtis L.
Abstract:: The Emigrant Pass volcanics (EPV) are a 38.3 to 36.4 Ma calc-alkaline volcanic center that erupted andesite and dacite, and a late series of felsic dikes along the south flank of the Carlin gold district in north-central Nevada. The EPV includes dacite and rhyolite porphyry dikes indistinguishable from porphyry dikes...
