The Sea in Maps and Pictures

In May, the Clinton Marine Survey AB began the bathymetric mapping in parts of the North Sea for the MAREANO programme. Until the beginning of August they will survey 2730 km².

The MAREANO programme plans to conduct bathymetric mapping in the North Sea this year. An invitation to tender for bathymetric mapping is published. 

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.

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.
