    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) over the well-defined seasonal cycle these two groups experience in surface waters of the Sargasso Sea. To this end, a suite of overlapping and complementary approaches for measuring growth and grazing mortality in natural picoplankton populations will be applied.
This work will involve both on-deck incubations and intensive water-column sampling. For the former, trace metal-clean Go-Flo samples will be required (see Other Comments, below). For the latter, CTD casts will be repeatedly made in the vicinity of a free-floating drogue (see Other Comments); drogue deployments will last ~36 hr.

    Other vehicle-related equipment (list):
    Science equipment to be installed on vehicle:
    Electronic equipment used in the ALVIN personnel sphere:
    Other comments and information:
-> Kevlar line is needed for trace metal-clean Go-Flo sampling (max depth = 100 m). This will require a SeaMac winch and a non-metallic metering block, both of which Jim Moffett uses regularly on the Oceanus. We will bring Go-Flo bottles, and borrow Kevlar line from Jim, if necessary.
-> Drogue is a "holey-sock," suspended at 60m depth or shallower, marked with a high-flier buoy with radio beacon (160.785 MHz) and strobe light.
-> Liquid Nitrogen will be used in the Main Lab (~3 35-liter Dewers) for sample storage. We will bring the dewers, but will need to arrange for delivery of liquid nitrogen just prior to departure.
