On May 2 (U.S. mainland)/May 1 (Northern Mariana Islands), 2016, during the first leg of the 2016 Deepwater Exploration of the Marianas expedition, we imaged, for the first time ever, this incredible active hydrothermal vent that rose 30 meters (98 feet) off the seafloor. It was gushing high-temperature fluid -- at one point, we measured a temperature of 339°C (642°F), one of the highest temperatures ever recorded at a hydrothermal vent in the Mariana region! In addition to amazing geology, this vent offered us a glimpse at some interesting biology, serving as a home to species ranging from Chorocaris shrimp, Munidopsis squat lobsters, Austinograea crabs, limpets, mussels, and snails.
