Science objectives

Determining the effects of ocean acidification on deep-water corals, surveys of potential new deep-water coral sites.

Science Activities

Collection of live deep-water corals, collection of water samples both by Alvin and by CTD casts over the dive sites, ship-board experiments on coral physiology, push cores in coral habitats, integration of sensors (pO2 and PCO2 optodes) with Sentry.

Pre-cruise planning meeting: Teleconference/Visit WHOI

I will be in the Boston area over the holidays, probably from Dec 20 - Jan 6, if a visit in that time frame is possible.
Media personnel on board: Video
Independent documentary film about ocean acidification and the deep sea.
