South Ostrobothnia ( Finnish : Etelä-Pohjanmaa ; Swedish : Södra Österbotten ) is one of the 19 regions of Finland . It borders the regions of Ostrobothnia , Central Ostrobothnia , Central Finland , Pirkanmaa , and Satakunta . Among the Finnish regions, South Ostrobothnia is the ninth largest in terms of population. Seinäjoki is the regional centre and by far the largest city in the area.
27-461: As a cultural area, South Ostrobothnia is larger than its current regional borders and includes the region of Ostrobothnia as well. The natural landscape of South Ostrobothnia is mainly expanses, which is Finland's largest plain area. South Ostrobothnia is connected to the coastal region of the Gulf of Bothnia in the west, to the river country of Central Ostrobothnia in the north, and to Suomenselkä in

In the south of the gulf lies Åland , between the Sea of Åland and the Archipelago Sea . Bothnia is a latinization . The Swedish name Bottenviken

While being repeatedly covered by glaciers during the last 2.5 million years glacial erosion has had a limited effect in changing the topography. It is estimated that within about 2,000 years, ongoing post-glacial rebound will raise
135-453: Is reached. This recovery rate will progressively slow as isostatic equilibrium is approached. Into the gulf flow a number of rivers from both sides; consequently, a salinity gradient exists from north to south. In the south the water is the normal brackish water of the Baltic Sea , but in the north, in the Bothnian Bay , the salinity is so low, from 0.4% near Kvarken to 0.2% in the northernmost part, that many freshwater fish such as

The depth and surface area of the Gulf of Bothnia are constantly decreasing, as the land is rising after it had been pressed down by about 2,600 to 3,300 feet (790 to 1,010 meters) by the continental ice during last ice age. The rise is 80 cm every hundred years. It is estimated that the land has a further 300 to 400 feet (91 to 122 meters) to rise before equilibrium
189-688: Is some fishery, mainly Baltic herring , for domestic needs. A persistent problem has been pollution, because the sea is enclosed by a large drainage basin and is poorly connected to fresher waters from the Atlantic. Mercury and PCB levels have been relatively high, although the Finnish Food Safety Authority considers the herring edible. Although the levels exceed the limits, the fatty acids have health benefits that offset this risk. 63°N 20°E / 63°N 20°E / 63; 20 Suupohja Suupohja
216-543: Is that of Nicolaus Germanus from the year 1482. The land surrounding the Gulf of Bothnia is heavily forested. Trees are logged, then transported to the coast for milling. The gulf is also important for oil transport to the coastal cities and ore transport to steel mills, for instance in Raahe. In terms of tonnage in international traffic, the largest ports on the Finnish side are Rauma, Kokkola and Tornio. The main ports of

Swedish is spoken by 637 people (0.3%). The highest shares of Swedish-speakers are in Evijärvi (2%) and Karijoki (1.6%), both of which border majority Swedish-speaking municipalities in the region of Ostrobothnia. The most spoken immigrant languages are Russian (0.5%), Estonian (0.4%), Ukrainian (0.2%), Hungarian (0.2%) and Thai (0.1%). South Ostrobothnia has

Julius Pokorny gives the extended Proto-Indo-European root as *bhudh-m(e)n with a *bhudh-no- variant, from which the Latin fundus , as in fundament , is derived.

The gulf is 725 km (450 mi) long, 80–240 km (50–149 mi) wide and has an average depth of 60 m (200 ft; 33 fathoms). The maximum depth is 295 m (968 ft; 161 fathoms).

It also ships forest products and oil. In port operations in the Gulf of Bothnia, icebreaker assistance can be required for an ice season that averages as long as six months; whereas in the Gulf of Finland, the icebreaking season averages only three months.

The river valleys of South Ostrobothnia have traditionally been flood -prone areas. South Ostrobothnia had its first permanent settlements during the Iron Age . Swedish control began in

Traffic restrictions for icebreaker assistance are typically in force for all the gulf from late January to late April and for the northernmost ports from the middle of December to the middle of May. Geologically the Gulf of Bothnia is an ancient depression of tectonic origin. The depression

The gulf is a combination of the Bothnian Bay in the north and the Bothnian Sea in the south, separated by the Kvarken region with a water depth of around 25 metres (82 ft) and a rate of land rising of almost 10 mm (0.39 inches) a year. Within 2000 years the bay is expected to separate from the rest of the gulf and become a freshwater lake. Being nearly fresh,
