ChEss scientists aboard the RRS James Cook are on an expedition to the East Scotia Ridge to explore areas of the deep seabed of the Southern Ocean to locate and investigate hot water vents (hydrothermal vents) and cold seeps. A follow up to an earlier expedition in which researchers mapped the seafloor, on this cruise researchers will be utilizing a remotely operated vehicle (ROV) working at depths of 2800 meters using high definition cameras to record the animals living in these extreme habitats.
