ROVs Deep Discoverer and Seirios
Remotely operated vehicles (ROV) Deep Discoverer and Seirios operate as a two-body system off NOAA Ship Okeanos Explorer. To ensure they’re able to livestream video and collect other deep-sea data during the 2026 season, the pair will have their own shakedown in May and June 2026. Seen here on the deck of Okeanos Explorer in the Gulf of Alaska, the ROVs were vital to the success of 2022’s Seascape Alaska expeditions.
