    Science objectives/activities planned:
This leg is supported by two NSF programs focusing on vent protists and viruses. Our primary research objective, centers on understanding the diversity and distribution of protists and viruses associated with hydrothermal vent systems. As primary grazers of the bacteria in marine systems we hope to discover if protists play a major role in structuring vent microbial communities. This will entail deploying and recovering many small protist collectors (proto-traps) in and around the vent system both in Guaymas and at 9N. We will also be collecting small water samples associated with each of the units for geochemical analysis. For the virus component, we will be collecting large volumes of water for protist, bacteria and viral studies with our free vehicle system (LVWS) and with the ships CTD. We will also be making discrete collections of Guaymas sediments, bivalves, Alvinellid worms, and Riftia.

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

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

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?
We will be bringing only minor volumes of each of these materials. As in the past we intend to 3 X contain all of them while in use (plastic holding container, plastic bag, leakage tray) and remove the unused portions and waste material from the ship at the earliest possible time. We will bring our own waste containers that will be consolidated, removed from the ship, and deposed of at each of our host institutions. PPE will be supplied to all those using hazardous material.
