The role of dissolved organic carbon (DOC) in the benthic                       carbon cycle of the deep sea will be defined by determining                     both the pore water concentration and the benthic flux of DOC.                  Six stations will be visited along a transect from Woods Hole                   MA, to Bermuda.  Carbon isotopic composition will be determined                 for pore water DOC and the DOC flux.  These measurements                        together with the results of a separately funded study of                       organic matter decomposition and calcium carbonated dissolution                 at the same sites, will yield the first complete mass and                       isotopic budgets for carbon at the sea floor.  In addition to                   providing the first quantitative estimate of DOC fluxes out of                  the sediments, these results are expected to (1) resolve an                     outstanding imbalance in present benthic stable isotope                         budgets, (2) constrain the role of bottom water carbonate ion                   in the neutralization of metabolic acids, and (3) help to                       define the source of food for the benthos.
