NOAA Ship Okeanos Explorer

Expedition Summary

From October 26 to November 15, NOAA Ocean Exploration and partners conducted a telepresence-enabled ocean exploration expedition on NOAA Ship Okeanos Explorer. The Windows to the Deep 2021: Southeast ROV and Mapping expedition collected critical information about unexplored and poorly understood deepwater areas of the Blake Plateau region of the North Atlantic Ocean. This foundational information will encourage further exploration and research and inform resource management decisions and activities in the region.

During Windows to the Deep 2021, at-sea and shore-based science teams worked together to explore and map the seafloor and the water column. Our 24-hour operations included ROV dives during the day and mapping operations at night. We used the state-of-the-art deepwater mapping systems on Okeanos Explorer, our dual-bodied ROV system that can dive to depths of 6,000 meters (3.7 miles), and a high-bandwidth satellite connection for real-time ship-to-shore communications.

During this expedition, we mapped and explored a variety of habitats and features in areas along the Southeast U.S. continental margin identified by the ocean management and scientific communities. Findings from this expedition build on our previous expeditions in the region. Collectively, these expeditions have contributed greatly to what we now know about environments along the southeastern edge of our continent.
