The water temperature in the surface layer was normal in the Skagerrak and Kattegat while it was slightly above normal in the Baltic Proper. Surface nutrients showed for the season almost normal values, except for silicate and phosphate which, in parts of the Baltic, were elevated.

The effects of the inflow during December 2014 were clearly visible during the expedition. The Bornholm Basin was now filled up to the sill depth with water having a salinity of about 18 psu and an oxygen content of 5.5 ml/l. In The Stolpe Furrow water with a salinity of 16 psu and an oxygen content of 4 ml/l was recorded at depths exceeding 60 meters. At the station BCSIII-10 in southeast a salinity of 12 psu, and an oxygen concentration of 2.8 ml/l was found at depths exceeding 82 m.
