Surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer were low and had increased since the last observation, which is normal for the season. The oxygen conditions in the Kattegat bottom water were relative good. The oxygen condition had improved in the Arkona Basin, which can be an effect of the inflow in the beginning of September. In the Bornholm Basin and the Hanö Bight the oxygen conditions had not changed since last expedition. Still no hydrogen sulphide was present.
