Mapping Monument Vent Sites

ROV Deep Discoverer is secure on deck following a successful dive today at Fina Nagu Caldera D. We are conducting overnight mapping operations overtop of Toto, Pika, Archaean and South Backarc – four of the hydrothermal vents that compose the Vents Unit of the Marianas Trench Marine National Monument. Tomorrow morning we will conduct CTD Pogo operations at Fina Nagu Caldera A to search for evidence of hydrothermal vent activity in the water column. Afterwards, we’ll deploy ROV Deep Discoverer for an ROV dive at Fina Nagu Caldera C. Tune back then to explore with us!
