    Science objectives/activities planned:
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) 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) 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) 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.

    Do you need non-standard wire?
NoIf so, what type?
    Do you need a traction winch?
No
Will you be bringing any equipment (winches, blocks, etc.) that lowers equipment over the side?

If yes, please provide details:
Will there be special requirements for:

    Electrical power
No
    Equipment handling
Yes
    Inter/intraship communications
No
    Science stowage
Yes

If yes to any of the above, please identify: Equipment will be deployed through stern A-frame; stowage, large number of sample bottles

Will any of the following items be used on board?

    Explosive devices
No
    Portable air compressors
No
    Flammable gases
No
    Radioisotopes
Yes
    Isotope van
Yes

Will hazardous material be used aboard, or deployed by an ROV? Yes

What measures or plans have been made a) in the event of a spill, and b) for the removal and/or disposal of these materials at the completion of the cruise?
Radioisotopes will be stored in special poly lined barrels. In 2004 we purchased appropriate barrels from WHOI, we wish to do this again.

Chemical Waste, weak acids, formaldehyde and nutrient autoanalyzer waste will be stored in drums on the weather deck and will be removed in Bermuda at the completion of the cruise.

All stock chemical brought on board and not used will be removed in Bermuda. We will have HCl acid on board for cleaning sampling gear during the course of the cruise. Ideally this will be stored out on deck in an appropriate chemical storage locker.

Chemical inventory sheets for our 2005 cruise are nearly identical to those used in our 2004 cruise.

Supplies for cleaning up spills will be brought on board as well as all appropriate protective gear (lab coats, safety glasses, etc.).
