First Station Starts Off with Sunshine, Corals and Sponges

Cruise diary: MAREANO’s second cruise to the Arctic Mid-Ocean Ridge (AMOR) has started with beautiful weather conditions and smooth sailing! The seas were calm and we made it to the first station within 42 hours of steaming.

We reached the first station on Thursday morning (16 April 2026) just after breakfast, all eager to see what the station had in store for us. But just as we caught sight of some bamboo corals and glass sponges while landing with the remotely operated vehicle, Ægir6000, from NORMAR, we experienced some technical difficulties that put the dive on hold for a couple of hours. However, the wait was completely worth it in the end.

Once we finally were able to get started on the video line, there was a sight to behold. The habitats alternated between bamboo coral gardens containing glass sponges, ascidians, and soft corals to patches of brittle star beds. At some point the bamboo coral framework completely covered the area, with living bamboo corals growing on top of the dead coral framework (similar to what we observed in October 2025). It was a quite exciting way to start the cruise, and we can’t wait for the stations to come!
