national monitoring programme are reported to ICES annually. Meta-data from both national (mainly open sea) and regional (coastal) monitoring programmes are reported to SeaDataNet. ICES are harvesting physical-chemical data from SeaDataNet OSPAR Assessment 2016 15 and due to this process Swedish coastal Last updated: Aug 01, 2017

found at depths exceeding 50 to 80 metres in all basins. Hydrogen sulphide was also found in all areas deeper than 70 to 90 metres.

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 Last updated: Apr 23, 2014

The surface temperature was normal for the season and varied between 8-11° C. At the west coast a pycnocline was observed at 10-20 meters and in the Baltic Proper the surface water was well mixed down to 30-40 meters.    The levels of nutrients in the surface water (0-10 m) were low but had started Last updated: Nov 19, 2019

remaining stations were cancelled. Due to this, large parts of the Baltic Proper were not sampled during the cruise, which was SMHI’s first on board R/V Aranda since July 2017. The sea surface temperature in the areas monitored was normal or below normal for the season. At most stations the temperature was Last updated: Mar 15, 2019

The sea surface temperature and salinity was normal in all sea areas, except the surface salinity that was above normal in parts of the Skagerrak, in the Eastern Gotland Basin and in the Hanö Bight. The deep water in parts of the Baltic Proper showed temperature and salinity above or high above Last updated: Jul 05, 2019

The sea surface temperature was between 2.9–6.5 ºC, coldest in the northern parts of the Baltic Proper and warmest in Skagerrak and Kattegat. The sea surface salinity was as highest 30.5 in the open Skagerrak and as lowest 6.8 in the Baltic Proper and the salinity was above normal at some stations Last updated: Apr 23, 2019
