ROVs are fantastic tools for underwater activities, like visual inspections of assets, habitat mapping, search and rescue, etc. Just one recent example is an ROV being used to visualize dredging activity for deep-sea quay construction in the Port of Rotterdam, Netherlands.
A recent event in Virginia USA demonstrates the value of ROVs in search and recovery situations:
A car was seen driving off the end of the Virginia Beach Fishing Pier a few days ago. Because of difficult water conditions on site, Virginia Police reached out to the Chesapeake Fire Department to request an ROV to learn more about the location of the vehicle and aid with its recovery.
Scientists from the Scripps Institution of Oceanography recently completed a comprehensive survey of the seabed floor off the coast of California using a combination of AUV and ROV, both rated to 6000m depths.
Researchers uncovered a shocking 350 square kilometres of discarded military munitions:
In 2023, Schmidt Ocean Institute scientists exploring with ROV Subastian have discovered four new octopus species at a depth of ~3,000m off Costa Rica. The octopus were found near two low-temperature hydrothermal springs.
One has been named the Dorado Octopus after the rock called El Dorado Hill where it was found. The others have yet to be formally described.
