Surface water temperatures in the Skagerrak and the Kattegat were above normal. High nutrient concentrations were found in the surface waters outside of Gullmarfjord, due to recent heavy rain. Concentrations in the southeastern Skagerrak were also high, due to influence from southern North Sea. An inflow to the Baltic was observed in the Sound. Oxygen concentrations below 2 ml/l were found in the Baltic Proper at depths exceeding 60 to 70 metres. Hydrogen sulphide was found in the western, northern and eastern Gotland Basins at depths greater than 70 to 125 metres.
