    Science objectives/activities planned:
(1) 1) Measure the daily time course of N input and uptake, within the euphotic zone of the Sargasso Sea, through several destratification/stratification events during the winter convective mixing period.
(2) 2) Quantify the main floristic changes (using a diversity of chemotaxonomic methods) and the size distribution change in the phytoplankton community during and after these destratifica-tion/stratification events.
(3) 3) Determine the fate of N (primarily particulate flux, DON export, non-gravitational flux or remineralization) that is detrained during destratification events in order to better understand the relationships between new production and export production.
(4) 4) Use the data collected to validate and enhance a 1-D model of the primary production and biogenic particle export cycle that has been developed for the BATS site, as well as increase the general robustness of biological/physical models for this and similar temperate latitude sites.
