The Kattegat and the southwestern Baltic Sea are well oxygenated and have a rich biology. The remainder of the Sea is brackish, poor in oxygen, and in species. Thus, statistically, the more of the entrance that is included in its definition,

The ice reaches its maximum extent in February or March; typical ice thickness in the northernmost areas in the Bothnian Bay , the northern basin of the Gulf of Bothnia, is about 70 cm (28 in) for landfast sea ice. The thickness decreases farther south. Freezing begins in the northern extremities of

Another explanation is that, while derived from the aforementioned root, the name of the sea is related to names for various forms of water and related substances in several European languages, that might have been originally associated with colors found in swamps (compare Proto-Slavic *bolto "swamp"). Yet another explanation

690-797: Is possible that Pliny refers to an island named Basilia ("the royal") in On the Ocean by Pytheas. Baltia also might be derived from "belt", and therein mean "near belt of sea, strait". Others have suggested that the name of the island originates from the Proto-Indo-European root *bʰel meaning "white, fair", which may echo the naming of seas after colours relating to the cardinal points (as per Black Sea and Red Sea ). This '*bʰel' root and basic meaning were retained in Lithuanian (as baltas ), Latvian (as balts ) and Slavic (as bely ). On this basis,
759-523: Is that the name originally meant "enclosed sea, bay" as opposed to open sea. In the Middle Ages the sea was known by a variety of names. The name Baltic Sea became dominant after 1600. Usage of Baltic and similar terms to denote the region east of the sea started only in the 19th century. The Baltic Sea was known in ancient Latin language sources as Mare Suebicum or even Mare Germanicum . Older native names in languages that used to be spoken on

Since the Viking Age , the Scandinavians have referred to the Baltic Sea as Austmarr ("Eastern Sea"). "Eastern Sea", appears in the Heimskringla and Eystra salt appears in Sörla þáttr . Saxo Grammaticus recorded in Gesta Danorum an older name, Gandvik , -vik being Old Norse for "bay", which implies that
1035-499: The Danish straits . According to the 18th-century natural historian William Derham , during the severe winters of 1703 and 1708, the ice cover reached as far as the Danish straits. Frequently, parts of the Gulf of Bothnia and the Gulf of Finland are frozen, in addition to coastal fringes in more southerly locations such as the Gulf of Riga. This description meant that the whole of the Baltic Sea

In the northernmost reaches of the Bothnian Bay, ice usually stays until late May; by early June it is practically always gone. However, in the famine year of 1867 remnants of ice were observed as late as 17 July near Uddskär . Even as far south as Øresund , remnants of ice have been observed in May on several occasions; near Taarbaek on 15 May 1942 and near Copenhagen on 11 May 1771. Drift ice

The Bothnian Sea , the basin south of Kvarken , freezes on average in late February. The Gulf of Finland and the Gulf of Riga freeze typically in late January. In 2011, the Gulf of Finland was completely frozen on 15 February. The ice extent depends on whether the winter is mild, moderate, or severe. In severe winters ice can form around southern Sweden and even in

The effects of the afore-mentioned high-pressure area did not reach the southern parts of the Baltic Sea, and thus the entire sea did not freeze over. However, floating ice was additionally observed near Świnoujście harbor in January 2010. In recent years before 2011,

He studied carefully the theory of naval warfare and in 1835-36 wrote a first plan for the construction of a Prussian fleet. Prussia at that time was a land power focused on Continental Europe, possessing practically no navy of its own; rather, it relied on the allied powers of Britain, the Netherlands , and Denmark . During

A surface layer of brackish water discharges 940 km (230 cu mi) per year into the North Sea . Due to the difference in salinity , by salinity permeation principle, a sub-surface layer of more saline water moving in the opposite direction brings in 475 km (114 cu mi) per year. It mixes very slowly with

The ice cover is the main habitat for two large mammals, the grey seal ( Halichoerus grypus ) and the Baltic ringed seal ( Pusa hispida botnica ), both of which feed underneath the ice and breed on its surface. Of these two seals, only the Baltic ringed seal suffers when there is not adequate ice in the Baltic Sea, as it feeds its young only while on ice. The grey seal
