    • Glacial influence on the geochemistry of riverine iron fluxes to the Gulf of Alaska and effects of deglaciation 

      Schroth, Andrew W.; Crusius, John; Chever, Fanny; Bostick, Benjamin C.; Rouxel, Olivier J. (American Geophysical Union, 2011-08-25)
      Riverine iron (Fe) derived from glacial weathering is a critical micronutrient source to ecosystems of the Gulf of Alaska (GoA). Here we demonstrate that the source and chemical nature of riverine Fe input to the GoA could ...
    • Sulfur species behavior in soil organic matter during decomposition 

      Schroth, Andrew W.; Bostick, Benjamin C.; Graham, Margaret; Kaste, James M.; Mitchell, Myron J.; Friedland, Andrew J. (American Geophysical Union, 2007-12-11)
      Soil organic matter (SOM) is a primary reservoir of terrestrial sulfur (S), but its role in the global S cycle remains poorly understood. We examine S speciation by X-ray absorption near-edge structure (XANES) spectroscopy ...
