Gulf of Bothnia

The Gulf of Bothnia lies at the north of the Baltic Sea and is exactly located between Finland's west coast and Sweden's east coast. Åland Islands lies in the south of the gulf between the Archipelago Sea and the Sea of Åland.

Geography

The gulf measures about 725 km (450 mi) long, 80-240 km (50-150 mi) wide and the average depth of gulf is about 60 m (200 ft, 33 fathoms). The greatest depth of the gulf is approximately 295 m (965 ft, 161 fathoms) and its surface area is about 117,000 km² (45,200 sq mi).

Many rivers drain into the gulf from both sides and so a salinity gradient is there from north to south. The gulf water in the south is usual salty water of the Baltic Sea. The saltiness is very low in the north side of gulf, in the Bothnian bay; therefore many freshwater fish flourish. The gulf is iced up over five months every year because the water is fresh.
