The Sea in Maps and Pictures

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.

On 6 March, a historic survey will begin in the North Sea. The MAREANO programme will use an uncrewed surface vessel (USV) to survey 675 square kilometres of seabed.

Cruise diary: During the second MAREANO cruise of 2025, we venture into the abyss of the deep sea along the Arctic Mid-Oceanic Ridge in the Norwegian sea, reaching depths of up to 3400 metres (Figure 1).
