2. 2015-10-17 Swedish Coastal Waters some areal facts Economical zone is about 155 000 km² Territorial water amounts to about 82 000 km² European Water Framework Directive (WFD) only contains about 36 000 km² But the whole Skagerrak, Kattegat and Baltic Sea may be regarded as coastal waters The length of the Swedish coastline is 11 500 or 32 000 km depending on definition About 100 000 islands Workshop on The status of European Coastal Observing and Fprecasting Systems, Majorca, October 2007

3. 2015-10-17 Swedish Coastal Waters physical and biological conditions From an almost oceanic condition in the Skagerrak the salinity decreases to about 1-2 psu in the northern Baltic. Great spatial and seasonal variation of physical, chemical and biological parameters Normal condition means that almost half of the Baltic is ice-covered during late winter The Baltic Sea with its brackish water contains many species that live on their outer edge of survival. Conditions may get worse as future climate may result in fresher water conditions. Typical salinity in the Baltic Harmful agea blooms during summer Workshop on The status of European Coastal Observing and Fprecasting Systems, Majorca, October 2007

4. 2015-10-17 Skagerrak Kattegat Bornholm basin East Gotland basin Increased acidic conditions in the Baltic Sea. Does it depend on increased absorption of atmospheric CO2 ?
