Regional distributed trends of sea ice volume in the Baltic Sea for the 30‑year period 1982 to 2019
Since more than 100 years, winters in the Baltic Sea have been classified according to their strength and have been compared to each other. In the beginning, the winter strength was only related to the ice coverage along the coasts. However, since the 1980s, also the ice thickness was observed consi...

Since more than 100 years, winters in the Baltic Sea have been classified according to their strength and have been compared to each other.

Owing to the international cooperation between the European ice services, we have all the needed information about the winter strength, sea ice coverage, distribution and mass for the entire Baltic Sea available. Thus, we have been able to compute changes in the sea ice conditions for this area covering the last decades and to compare them with changes in the air and sea surface temperatures.
