In January 2012, an international research group aboard research vessel Atlantis completed an expedition to study the world’s deepest-known hydrothermal vents, at the Mid-Cayman Rise in the Caribbean. The group, led by WHOI marine geochemist Chris German, collected samples and images at depths ranging from 2,300 to 5,000 meters using the remotely-operated vehicle Jason (the vehicle’s robotic arm is visible here). Deep-sea shrimp thrived at one site, named Von Damm, named for the late scientist Karen Von Damm, a graduate of the MIT/WHOI Joint Program.(Photo courtesy of Chris German, Woods Hole Oceanographic Institution)
