Seafloor Mapping FSM

After moving out of the region around the Mariana Islands impacted by Super Typhoon Dolphin’s heightened wind and swells, we are now safely in the EEZ of the Federated States of Micronesia (FSM). We are grateful to have been granted a permit by the National Oceanic Resource Management Authority of the Federated States of Micronesia (FSM NORMA) to assist them in gathering mapping data and potentially ROV and AUV surveys within priority regions (black lines) of their national waters. Orange icons indicate previous deep-sea observations of the seafloor in FSM dating back to the 1960s from Lamont-Doherty Earth Observatory's R/V Vema. There's an enormous amount left to learn about this massive ocean nation.
