Other Research
We are studying the geochemistry and microbiology (V. Orphan-Caltech) of anoxic sediments with respect to a peculiar feature-the remarkably linear sulfate gradient. (M. Alperin-UNC) 
How sediments (trace metal content) and stromatolites can be paleoceanographic and paleoclimatological repositories. (J. McManus-OSU, F. Corsetti-USC)
The global budget of N: N-fixation in margin settings, DON cycling, role of metals in denitrification etc. (Capone-USC, Knapp-U.Miami, Sanudo-Wilhemy-USC)
Global carbonate budgets and how they may change over time, also specific diagenetic reactions that affect carbonate preservation and dissolution.
How P gets sequestered in sediments and sedimentary rocks. (F. Corsetti-USC)
We are studying the biosignature of magnetite-bearing bacteria associated with iron and manganese oxides within deep sea sediments. (S. Lund-USC, K. Edwards-USC)
Groundwater exchange with the coastal ocean, chemical tracers. (D. Hammond-USC)
