Bothnian Bay

The Bothnian Bay stretches out from Kvarken in the south to its northernmost point in the Torne River estuary in the Tornio–Haparanda area. There are very few islands on the coastline of the Bothnian Bay, and sandy seabeds are common. The shorelines of the islands are rocky, but there are hardly any rocky beaches in the area. Post-glacial rebound continues to have a strong impact on the coastline of the Bothnian Bay. Many major rivers flow into the Bothnian Bay, including the largest salmon river of the Baltic Sea, i.e. the Torne. Each year, a significant number of the salmon in the Baltic Sea run via the Bothnian Bay to spawn. Other great rivers that flow into the Bothnian Bay include Kemijoki, Oulujoki, Luulajanjoki and the Kalix.

The salinity of the surface waters of the Baltic Sea diminishes towards the north, and in the Bay of Bothnia, just like in the eastern end of the Gulf of Finland, the water of the Baltic Sea is actually almost fresh. The number of species that thrive in the Baltic Sea also diminishes when we move from southern Baltic Sea towards the north. The low salinity of the northern Baltic Sea, cold winters, and the sea freezing over all pose challenges for animal and plant adaptation. The Bothnian Bay is relatively low in nutrients, and since the load caused by humans is also lower than in other areas of the Baltic Sea, the Bothnian Bay and Kvarken are home to the only parts of the Baltic Sea that can currently claim to have a good status (Helcom).


Choose a spot on the map and make a donation! With your help, we are realising concrete Baltic Sea conservation operations as well as making sure that the stories of the sea will be preserved for future generations.


Found your own Baltic Sea team and recruit others to raise more for your team’s donation pot. The team could be organised for a holiday collection or corporate donation, for example.

Information about the page

This page is a symbolic indication of how, with the help of the John Nurminen Foundation, the Baltic Sea and its cultural heritage is being conserved. The decrease in nutrient emissions affects the entire area of the Baltic Sea, and your donation cannot be specifically targeted only to your chosen spot to improve water quality. Our cultural heritage work also covers the entire scope of the Baltic Sea. Our wish is to raise awareness about the Baltic Sea’s unique qualities and history to as large an audience as possible, so that people can learn to value and conserve our beloved sea.

In addition, we vow that our work is driven by substantial results and effectiveness. We are unaffiliated: our work is driven solely by the desire to conserve the Baltic Sea.
