This is new study of the nutrient dynamics of silica                       in the Sargasso Sea.  The field work will be done at                            Station S south of Bermuda, a site with good historical                         biological oceanographic data as well as ongoing studies.                       The study will use a new high sensitivity silica technique                      and collaborates with a new proposal by McCarthy and                            Garside that is centered on the nitrogen dynamics of the                        same system.  Both uptake and dissolution of silica in                          surface waters will be measured, as well as the ambient                         concentrations and the particulate flux in sediment traps.                      Silica dynamics are mainly influenced by diatom growth and                      removal processes and this study will be one of the first                       to focus on the distribution of diatoms in the Sargasso                         Sea.
