This site had a fantastic “amphitheater of chemosynthetic life.” Here we saw bathymodiolus mussels, methane hydrate or ice, and ice worms. There were also a number of sea urchins, sea stars, and fish in this area. Most impressive about this ledge was large accumulation of hydrates under the ledge as well as the large collection of mussels hanging upside down and a group of mussels that hung down off the ledge.
