Finland – January 22nd, 2013

The Bothnian Sea is the southern part of the Gulf of Bothnia, which is situated between Sweden, to the West, Finland, to the East, and the Sea of Åland and Archipelago Sea to the South. The Bothnian Sea, with a surface area of approximately 79,000 km², occupies about one-fifth of the total of the Baltic Sea.

The Bothnian Sea is different from other sea areas of the Baltic Sea. On the whole it is good condition and its open sea is even in excellent condition. On the other hand, eutrophication, the ecosystem response of an aquatic system to the addition of artificial or natural substances, such as nitrates and phosphates through fertilizers or sewage, is threatening to increase, both in the open sea and near the coast. Eutrophication exemplifies the deterioration in the condition of the sea. Climate change, chemicalisation and changes in species also present challenges.
