Mareano expedition completed

Expedition diary: It is 18:25 on Sunday evening, and where we are, the sea is almost 500 metres deep. Our video rig hovers lazily over the sea floor. It is completing the final metres of a total of 33.4 kilometres of video transects on the Spitsbergen Bank, before G.O. Sars can set sail for Tromsø.

Strong currents shaping the seafloor of Spitsbergenbanken

05.10.2021

Cruise diary: When we arrived at Spitsbergenbanken a few days ago, we were met by strong currents. On the seafloor, the currents shape sediments into different types of bedforms, with the most common being ripples, which are centimetres to decimetres high, but also larger bedforms such as sandwaves, or sandbanks which can be more than 10 m high.
