Ægir – observing life at the ocean floor

While most Norwegians associate Ægir with something else, did you know that Ægir is the jötunn (some kind of god) of the oceans? Here on board of RV Kronprins Haakon, we have an ROV (remotely operated vehicle) called Ægir  https://oceanlab-no.weebly.com/rov.html which is some kind of robot that dives along the ocean floor filming and picking up whatever could be interesting to study. It is attached to a winch on the ship and can go down to 6000 m depth! While it films the ocean floor, we can watch the movies live from the ship. Like that, the biologists on board can tell the ROV-pilots which animals, corals, sponges or other plants should be picked up or sucked up with the ROV and brought on board for later studies.

It was very unclear to us, how the ocean floor would look like in Dronning Maud Land and what to expect, so it was very exciting to watch! Here is a collection of pictures that the ROV took of corals, fish, anemones, sponges, squid, sea stars and jellyfish.
