To start, we began with the discovery of extensive new biological communities, including both tubeworms and shrimp, hosted in diffuse hydrothermal flow. We also found new chimney structures in the same area, emitting hot clear fluid in a much more focused manner. By lunchtime it was time to prepare for a VIP event with both the Silver Spring Exploration Command Center and URI’s Inner Space Center. During the event shore-side participants watched live video feeds coming from Okeanos Explorer of an active hydrothermal vent habitat swarming with shrimp ~2300m deep at the Mid-Cayman Rise, and footage from the E/V Nautilus exploring an ancient shipwreck in the Black Sea. Shore-side attendees had the opportunity to hear about the operations of both ships, and ask questions about the ongoing explorations. Then by 2pm we were back at work exploring new parts of the seafloor and testing a new approach – following sonar targets identified from a prior AUV survey (generously shared with us by shipboard scientist Paul Tyler and his UK colleagues from NOCS, Southampton). On three occasions this afternoon, wherever we visited such sonar targets, we found rocks outcropping, at least some measure of fluid flow out of the seafloor and extensive deep sea coral communities ± other fauna.
