    Science objectives/activities planned:
The primary objective of the project is to examine the relationships between growth rate, grazing mortality, and relative abundance for two pico-phytoplankton groups (Prochlorococcus and Synechococcus) in surface waters of the Sargasso Sea. On-board flow cytometry will be used to assess the abundance of these phytoplankton. A suite of experimental approaches for measuring growth and grazing mortality in natural picoplankton populations will also be applied.

This work will involve both on-deck incubations and intensive water-column sampling. For incubations, trace metal-clean Go-Flo samples will be required (see Other Comments, below). For the water-column measurements, CTD casts will be repeatedly made in the vicinity of a free-drifting drogue (see Other Comments); drogue deployments will last ~36 hr.

We plan to occupy 2 or 3 major stations, with 1 or 2 drogue deployments and experimental series at each. Additional short stations along the transect from WHOI to BATS will also be made.
