After 13 years of excellent service and 2,269 days at sea, OET is retiring our trusty EM302 multibeam. During this time, we successfully mapped 1.3 million km² of seafloor: an area roughly the size of California three times over! This data has been a critical part of our contributions to the Seabed 2030 initiative and the US National Strategy for Mapping, Exploration, and Characterization. Stay tuned to learn all about the newest systems installed on E/V Nautilus for future seafloor mapping! 

OET proudly welcomes Sabrina Medina, Education Program coordinator with the Maui Ocean Center Marine Institute, to our 2026 Science Communication Fellowship cohort! Learn more via Maui Now.

Happy World Reef Day! Did you know that much of Earth's reefs are actually found in the deep sea? While exploring unknown regions of our global oceans, OET uses our remotely-operated vehicles to shine a light on these dark-dwelling corals and share their wonder with the world.
