The
Baltic Sea is located in
Northern Europe, bounded by the
Scandinavian Peninsula, the mainlands of
Northern Europe,
Eastern Europe,
Central Europe, and the
Danish islands. It drains into the
Kattegat by way of the
Öresund, the
Great Belt and the
Little Belt. Kattegat then continues in the
Skagerrak into the
North Sea and the
Atlantic Ocean. The Baltic Sea is linked to the
White Sea by the White Sea Canal and directly to the North Sea by the
Kiel Canal.
The Baltic Sea
Name
The first one to name it the
Baltic Sea was
Adam of Bremen and he seems to have based it on a large island,
Baltia, mentioned by
Xenophon and located in northern Europe. It is possibly connected to the Germanic
belt, a name used for some of the Danish straits, while others claim it to be derived from
Latin balteus (belt)
http://www.lysator.liu.se/runeberg/nfbb/0435.html. From this use,
Baltic has been applied to the
Baltic countries. Another proposed derivation from the
Indo-European root
- bhel meaning white, shining seems speculative.
The Baltic Sea is known by the equivalents of "East Sea", "West Sea", or "Baltic Sea" in different languages:
- In the Baltic-Finnic languages spoken in the countries bordering the Gulf of Finland the naming varies by geography: in Estonian it is called West Sea (''Läänemeri''), while Finnish has East Sea (''Itämeri'').
Prehistory
The Baltic Sea is a very young sea, formed by the last
ice age. As the ice receded to north, the following stages of the Baltic formed:
- Baltic Ice Lake 13000 BC
- Yoldian Sea 10300 BC
- Ancylus Lake 9500 BC
- Mastogloia Sea 8500 BC
- Littorina Sea 7500 BC
- Post-Littorina Sea 4000 BC - current
As the ground rose after being pressed down by the ice, the Baltic Sea switched between being a sea and a lake, or something in between, and it was variously connected to the
North Sea-
Atlantic either through the straits of
Denmark or at what are now the large lakes of
Sweden, and the
White Sea-Arctic Sea. Many of the stages are named after certain marine animals (like the Littorina mollusc) that are clear markers of changing water temperatures and salinity.
The Baltic Sea somewhat resembles a
riverbed, with two tributaries (the
Gulf of Finland and
Gulf of Bothnia). From
geological surveys it has become apparent that there indeed was a river in the area in the
Pleistocene: the
Eridanos.
Due to the
Post-glacial rebound, the ground is still rising after having been released from the weight of the Weichsel glaciation, especially around the Gulf of Bothnia: at places the ground is rising by almost one metre per century, which means that the shore can gain dozens and in some shallow places hundreds of meters in a human lifetime.
History
At the time of the
Roman Empire, the Baltic Sea was known as the
Mare Suebicum or
Mare Sarmaticum. Tacitus in his AD 98
Agricola and
Germania described the Mare Suebicum, named for the
Suebi tribe, during the spring months, as a
brackish sea when the ice on the Baltic Sea broke apart and chunks floated about. The Sarmatian tribes inhabited Eastern Europe and southern Russia.
Jordanes called it the
Germanic Sea in his work the Getica.
Since the
Viking age, the Scandinavians have called it "the Eastern Lake" (''Austmarr'', "Eastern Sea", appears in the
Heimskringla), but
Saxo Grammaticus recorded in
Gesta Danorum an older name
Gandvik,
"-vik" being Old Norse for "bay", which implies that the Vikings correctly regarded it as an inlet of the sea. (Another form of the name, "Grandvik", attested in at least one English translation of Gesta Danorum, is likely to be a misspelling.)
In addition to
fish the sea also provides
amber, especially from its southern shores. The bordering countries have traditionally provided
lumber,
wood tar,
flax,
hemp, and
furs. Sweden had from early medieval times also a flourishing
mining industry, especially on
iron ore and
silver.
Poland had and still has extensive
salt mines. All this has provided for rich trading since the Roman times.
In the early Middle Ages, Vikings of Scandinavia fought for power over the sea with
Slavic Pomeranians. The Vikings used the rivers of Russia for trade routes, finding their way eventually all the way to
Black Sea and southern Russia.
Finland and the Baltic states were the last in Europe to be converted into
Christianity in the
Northern Crusades: the former in the 12th century by the Swedes and the latter in the 13th century by the Germans. First the
Livonian Brothers of the Sword and then the powerful German
Teutonic Knights held the Baltic countries and fought with Danes and the Swedes, while the foundations of
Russia were being laid in
Novgorod.
Later on, the strongest economic force in Northern Europe became the
Hanseatic league, which used the Baltic Sea to establish trade routes between its member cities. In the 16th and early 17th centuries,
Poland,
Denmark and
Sweden fought wars for
Dominium Maris Baltici (Ruling over the Baltic Sea). Eventually, it was the Swedish empire that virtually encompassed the Baltic Sea. In Sweden the sea was then referred to as
Mare Nostrum Balticum (Our Baltic Sea).
In the 18th century
Russia and
Prussia became the leading powers over the sea. Russia's Peter the Great saw the strategic importance of the Baltic and decided to found his new capital,
Saint Petersburg at the mouth of the
Neva river at the east end of the
Gulf of Finland. There was much trading not just within the Baltic region but also with the North Sea region, especially the eastern
England and the
Netherlands: their fleets needed the Baltic timber, tar, flax and hemp.
During the
Crimean War a joint fleet of
Britain and
France attacked Russian fortresses by bombarding Sveaborg that guards
Helsinki and Kronstadt that guards
Saint Petersburg and destroying
Bomarsund in the Åland Islands. After the unification of
Germany in 1871, the whole southern coast became German. The
First World War was fought also on the Baltic Sea. After 1920
Poland returned to the Baltic Sea, and Polish ports of
Gdynia and
Gdansk (German:Danzig) became leading ports of the Baltic.
During the Second World War Germany reclaimed all of the southern shore and much of the eastern by occupying Poland and the Baltic states. In 1945 the Baltic Sea became a mass grave for drowned people on torpedoed
refugee ships. As of 2004, the sinking of the
troopship Wilhelm Gustloff remains the worst maritime disaster of all time, killing (very roughly) 9,000 people.
After 1945 the sea was a border between conflicted military blocks: in case of military conflict in Germany, in parallel with a Soviet offensive towards the
Atlantic Ocean, communist Poland's fleet was prepared to invade Danish isles.
In May 2004, the Baltic Sea became almost completely a
European Union internal sea when the Baltic states and
Poland became parts of the European Union, leaving only the Russian
metropolis of
Saint Petersburg and the
enclave of
Kaliningrad as non-EU areas.
The Baltic Sea starts to get very rough with the October storms. These winter storms have been the cause of many shipwrecks, like for example the
Estonia in 1994. But thanks to the cold brackish water where the
shipworm cannot survive, the sea is a time capsule for centuries-old shipwrecks. Perhaps the most famous one is the
Vasa.
Subdivisions
The northern part of the Baltic Sea is known as the
Gulf of Bothnia out of which the northernmost part is referred to as the Bay of Bothnia. Immediately to the south of it lies the Sea of Åland. The
Gulf of Finland connects the Baltic Sea with
St. Petersburg. The Northern Baltic Sea lies between the
Stockholm area, southwestern Finland, and Estonia. The Western and Eastern Gotland Basins form the major parts of the Central Baltic Sea. The
Gulf of Riga lies between
Riga and
Saaremaa. Bay of Gdansk lies east of the
Hel peninsula on the Polish coast and west of Sambia in
Kaliningrad Oblast.
Bay of Pomerania lies north of the islands of
Usedom and
Wolin, east of
Rügen. Bornholm Basin is the area east of
Bornholm and Arkona Basin extends from Bornholm to the Danish isles of
Falster and
Zealand. Between Falster and the German coast lie the
Bay of Mecklenburg and
Bay of Lübeck. The westernmost part of the Baltic Sea is the
Bay of Kiel. The
Sound, the Belts, and the
Kattegat connect the Baltic Sea with the
Skagerrak and the
North Sea. The confluence of these two seas at
Skagen on the northern tip of
Denmark is a visual spectacle visited by many tourists each year.
Biology
Phytoplankton bloom in the Baltic Sea (July 3, 2001)
The Baltic Sea is very shallow (average 57 meters, max. 459 meters), and because the straits of Denmark are quite narrow, the waters of the Baltic are not regularly exchanged with the cold waters of the Atlantic. The flow of the rivers into the Baltic is quite high, however, and as a result the
salinity of water in the Baltic Sea is somewhere between freshwater and seawater, known as brackish water. The low salinity has led to many slightly divergent species, like the Baltic Sea
herring that is a smaller variant of the
Atlantic herring. The
benthic fauna consists maintly of
Monoporeia affinis, which is originally a freshwater species. The Baltic Sea also has practically no tides, which also has affected the marine species as compared with the Atlantic.
The Baltic Sea is surrounded by countries practicing a lot of agriculture, which leads into a lot of fertilizers getting into the sea (also, the city of
Saint Petersburg still doesn't process much of its waste water), and therefore every summer a lot of
algae blooming takes place.
Economy
In 1999 the huge
bridge over
the Sound limited the Baltic Sea to the middle-sized vessels (see:
Oresund Bridge). In meantime, the Baltic Sea is the main trade route for export of Russian oil. Many of the neighboring countries are rather concerned about this, since a major oil leak would be disastrous in the Baltic given the slow exchange of water, and the many unique species. The tourism industries, especially in economies dependent on tourism like for example in northeastern Germany, are naturally very concerned.
Shipbuilding is practiced in many large shipyards around the Baltic:
Gdansk in Poland, HDW in
Kiel, Germany,
Karlskrona and
Kockums AB in
Malmö, Sweden, and
Rauma,
Turku,
Helsinki in Finland and
Klaipeda in Lithuania.
There are several cargo and passanger
ferry operators on the Baltic Sea, such as
Silja Line,
Viking Line, Tallink and Superfastferries.
