We left Copenhagen in the evening of the 11th April and sailed towards the Baltic Proper. It was time to do the first scuba diving on this expedition, and the weather was just perfect for this. Four divers dived at a ridge in Kalmarsund – which separates the mainland of Sweden and Öland. The 2 degree cold water was not an obstacle for our divers, and the marine habitat was filmed and photographed intensively. Although the diversity of species is low in this area, we got interesting photos of horse mussels, scorpion fish and crustaceans, including isopods and shrimps.
After the cold dive, Hanse Explorer continued to sail up north, where Oceana the coming days will explore the deepest areas of the Baltic Sea.
