Surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer were at low concentrations, which is normal for the season. The oxygen conditions in the Kattegat bottom water were good, while they were relatively poor in the southern Baltic Sea. In the Bornholm Basin the oxygen conditions had deteriorated since the former expedition, though no hydrogen sulphide was present. The next expedition is planned to take place August 20-24, when the Baltic Proper will be investigated.
