AUVs docking on seafloor

Riviera Maritime Media reported a recent demonstration by Saab showing their Sabretooth AUV’s ability to perform tasks like inspection and maintenance, and return to a subsea docking station for recharging and video download. Quite amazing advance that will allow ROVs/AUVs to stay at depth for dramatically longer periods.

Blue Robotics’ BlueROV2 is also capable of being “permanently submerged” at >800m, which MBARI and The Quest Institute working together with others have done with their unit:

New type of “ROV”?

We are about all things ROV, but this news wasn’t what we were expecting. Researchers at University of Richmond’s Lambert Behavioural Neuroscience Laboratory are studying rats trained to drive a “Rat Operated Vehicle” in order to advance human mental health treatment. Maybe an underwater ROV will be the next training session for the rats?

So great to hear such excitement in the voices of the NOAA researchers!

Whale Fall Actively Devoured by Scavengers at Davidson Seamount

Whale look what we have here! During the final dive of this year’s Nautilus expedition season, our team discovered a whale fall while exploring Davidson Seamount off central California’s coast with researchers from NOAA's Monterey Bay National Marine Sanctuary. The skeletal remains of this relatively recent fall are of a baleen whale estimated to be 4-5 meters long, and the team is working to identify the species. The site exhibits an interesting mid-stage of ecological succession, as both large scavengers like eel pouts and octopus are still stripping the skeleton of blubber, and bone-eating Osedax worms are starting to dissolve the bones.
