Reactions that take place at the sediment-water interface               and within the sediment column under oceanic regions of high                    productivity significantly affect the global budgets of nitrogen,               oxygen, carbon, and silica.  The Principal Investigators have                   been successful in using in situ benthic flux chambers to                       directly measure fluxes of these elements and have described                    their cycling within the basins of the southern California                      borderland.  They are proposing to continue this type of work by:               (1) building individual flux chambers for use with the                          submersible Alvin in order to directly study the effects of the                 disturbance from chamber deployment to the sediment-water                       interface on benthic exchange rates; (2) deploying landers in                   Santa Monica Basin in order to measure nitrate uptake rates that                will enable us to confirm estimates of the rates of oxygen and                  nitrogen cycling in these coastal sediments.  The purpose of                    building individual chambers is to perform manipulative                         experiments with the aid of Alvin and quantify the relationship                 between disturbance to the sediment-water interface and benthic                 exchange rates.  This will establish an accurate value for                      benthic exchange of nitrogenous compounds, silica, oxygen and                   carbon species.
