This is an investigation of the cycling and speciation of               germanium, selenium, arsenic, and antimony in the Black Sea, the                world's largest permanently-anoxic marine basin.  The PI's will                 obtain detailed depth profiles of dissolved and suspended                       particulate speciation (oxidation states and organic forms)                     through the oxic, suboxic, and anoxic zones of the water column,                and in the underlying sediment and pore waters.  This                           comprehensive data set will clarify the roles of marine                         aerobic/anaerobic metabolism and particulate scavenging on the                  redox behavior, speciation, and concentration of metalloid                      elements.  Time scales of processes will be deduced from data                   generated by other groups on the same expedition (e.g., water                   circulation:  T/He;/ 14C; Fe/Mn oxidation-reduction and                         scavenging rates; microbial activity).  The Black Sea is an ideal               environment for this work because its anoxic waters have a long                 residence time (ca. 1000 yrs.) and are in quasi-steady state, and               because of the intense and well-defined iron and manganese                      cycling in the vicinity of the oxic/anoxic interface.
