Expedition Summary

From August 23 - September 14, NOAA Ocean Exploration and partners conducted the fifth in a series of Seascape Alaska expeditions on NOAA Ship Okeanos Explorer. Operations during this 23-day expedition included 19 successful remotely operated vehicle (ROV) dives conducted in water depths ranging from 253 - 4,262 meters (830 - 13,983 feet), mapping of 28,287 square kilometers (10,922 square miles) of seafloor, and the collection of a wide variety of biological and geological samples. Altogether, data from the Seascape Alaska 5: Gulf of Alaska Remotely Operated Vehicle Exploration and Mapping expedition will contribute to our collective baseline understanding of the ocean, improving our ability to protect and manage marine ecosystems and furthering public awareness of the splendor, importance, and interconnectivity of the ocean to our everyday lives.

Naming every participant in a telepresence-enabled expedition is next to impossible, as scientists from around the world have provided input into the expedition plan. However, we've assembled information about the members of the team who are sailing on the ship and participating in the expedition from sea – meet the team!
