Expedition diary: As we arrive in the north with RV Kronprins Haakon, we are greeted by a brand new white world of icebergs and sea ice.

Expedition diary: And now for something completely different. Standard MAREANO sampling cruises collect biology, geology and chemistry data using video and physical sampling. This cruise is dedicated to exploring new methods, specifically, what MAREANO could gain from the use of autonomous underwater vehicles (AUVs).
