    Science objectives/activities planned:
The main objectives of this cruise are: 1) to collect vent animals, transport them to the surface, and use them for studies of reproduction, development, symbiosis and physiology, 2) to collect living near-bottom larvae with free-standing plankton pumps, 3) to study various aspects of reproductive biology in situ by deploying and recovering egg traps, incubation chambers and larval traps, 4)to determine the abundance and distribution of vent crabs on and off axis using traps and visual surveys, 5) to measure oxygen levels in hydrothermal vent fluids using a new instrument attached to Alvin, and 6) to transport alvinellid worms to the surface in a heated pressure vessel for lab experiments on physiology and survival.
