A video from a ROV mission under drifting sea ice to help with getting some oceanographic measurements. A sensor to detect tiny interactions between the ocean and sea ice was deployed, and because it can't be seen from above it was not quite in the right place for good measurements.

Solution? Swim a camera to it and have a look - and help get it right. It takes two people to swim a ROV - pilot and cable manager working together, here also accounting for ice drift and under ice current to avoid tangles. It also took a team to work on the oceanography side, helping us get the camera to the right place, and relaying instructions about instrument placement.

The end result? Measurements were achieved!

There's no soundtrack, imagine generator noises, a bit of wind and some yelling back and forth between the ROV team and the instrument arm operator. Field work was funded by the Nansen Legacy, RCN grant 276730. Video production is an unfunded personal project aiming to share work which happened, yet would otherwise vanish.

So, sit back and check out this little snapshot of how things look below the icy cap of the Arctic...
