NOAA Ship Okeanos Explorer has returned to Honolulu, Hawai‘i, following the successful completion of the Beyond the Blue: 2025 ROV and Mapping Shakedown expedition, during which the team was able to assess the readiness of remotely operated vehicles (ROV) Deep Discoverer and Seirios along with the ship’s mapping, telepresence, and other systems needed to conduct scientific activities. Our next expedition, Beyond the Blue: Papahānaumokuākea ROV and Mapping, will take place from April 8-May 5, 2025, and will include include daytime ROV dives to explore the seafloor and water column, overnight mapping operations, and continuous shore-side participation via telepresence technology.

All things permitting, when the ship is not in transit, dives will be streamed most days, April 11 to May 2, from approximately 7 a.m. to 5 p.m. HDT / 1 p.m. to 11 p.m. EDT. Note that dates and times are subject to change.
