Surface water temperatures were normal for the season in all investigated areas. All nutrients, in the surface layer, showed normal values for the season, except for phosphate which had concentrations below typical values for the summer season in the southwestern part of the Baltic Proper. Oxygen concentrations in the bottom water of the Arkona Basin were around 4 ml/l. In the Bornholm Basin oxygen values had decreased since the last visit and were now just below 2 ml/l. In the Hanö Bight oxygen concentrations were 0.7 ml/l.
