The Bothnian Bay is the northern part of the Gulf of Bothnia and is as such located in-between Sweden and Finland. It is the northernmost part of the Baltic Sea. To its south lies the Bothnian Sea, with which it forms the Gulf of Bothnia. The Bothnian Bay has a surface area of around 36,800 km2. Due to moving tectonics, the land holding the bay is still rising, and within 2,000 years, the bay will become a large freshwater lake. Due to its high latitude, the bay freezes annually up to six months, and has little plant or animal life compared to the rest of the Baltic.
