ROV Deep Discoverer
Top-down view of remotely operated vehicle (ROV) Deep Discoverer, captured from ROV Seirios during Dive 11 of the 2026 American Samoa ROV + Mapping Exploration expedition. Seirios is tethered via a cable to NOAA Ship Okeanos Explorer and Deep Discoverer, absorbing ship heave to keep Deep Discoverer stable while providing power, data transfer, and an expanded view for ROV pilots.
