Creator:: McManus, James, Berelson, William M., Hammond, Douglas E., and Klinkhammer, Gary P.
Abstract:: Benthic incubation chambers have been deployed in a variety of geochemical environments that provide a comprehensive geochemical framework from which to address issues related to Ba geochemistry and the use of Ba as a paleoproxy. First order budgets for barium show that in the equatorial Pacific, present rates of Ba...

Abstract:: Benthic chamber measurements of the reactants and products involved with biogenic matter diagenesis (oxygen, ammonium, nitrate, silicate, phosphate, TCO₂, alkalinity) were used to define fluxes of these solutes into and out of the sediments off southern and central California. Onshore to offshore transects indicate many similarities in benthic fluxes between...

Creator:: Wheat, C. Geoffrey, McManus, James, Dymond, Jack, Collier, Robert W., and Whiticar, Michael
Abstract:: We present evidence for pore water flow through the sediment of Crater Lake, Oregon based on systematic variations in pore water chemical compositions and thermal gradients. Pore water was extracted from sediment by centrifugation and diffusive exchange using a gravity corer deployed from a surface vessel and a box corer...

Creator:: Wheat, C. Geoffrey and McManus, James
Abstract:: We present concentrations of germanium and silicon in sediment pore waters, basaltic formation fluids, and bulk sediment from three ridge flank hydrothermal systems (RFHS). Basaltic formation fluids from warm (>30°C) RFHS have much higher Ge concentrations and Ge:Si molar ratios than overlying sediment pore waters, requiring seawater-basalt reactions to dominate...
