Historically, the Kingdom of Denmark collected Sound Dues from ships at the border between the ocean and the land-locked Baltic Sea, in tandem: in the Øresund at Kronborg castle near Helsingør ; in
534-457: A related hypothesis holds that the name originated from this Indo-European root via a Baltic language such as Lithuanian. 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

From 1872, there exist regular and reliable records of water levels in the Baltic Sea. The highest was the flood of 1872 when the water was an average of 2.43 m (8 ft 0 in) above sea level at Warnemünde and a maximum of 2.83 m (9 ft 3 in) above sea level in Warnemünde. In
1424-780: The Black Sea and southern Russia. This Norse-dominated period is referred to as the Viking Age . 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
1513-455: 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

The narrowest part of Little Belt is the "Middelfart Sund" near Middelfart . Geographers widely agree that the preferred physical border between the Baltic and North Seas is the Langelandsbælt (the southern part of the Great Belt strait near Langeland ) and the Drogden -Sill strait. The Drogden Sill

Sweden had from early medieval times exported iron and silver mined there, while Poland had and still has extensive salt mines. Thus, the Baltic Sea has long been crossed by much merchant shipping. The lands on the Baltic's eastern shore were among

After the Battle of Trafalgar in 1805 the rank of admiral of the red was introduced. The number of officers holding each rank steadily increased throughout the 18th and early 19th centuries. In 1769 there were 29 admirals of various grades; by

2848-645: 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 where the ice broke apart and chunks floated about. The Suebi eventually migrated southwest to temporarily reside in the Rhineland area of modern Germany, where their name survives in

In 2005, a Russian group of scientists found over five thousand airplane wrecks, sunken warships, and other material, mainly from World War II, on
3204-575: The Bothnian Bay and the Bothnian Sea were frozen with solid ice near the Baltic coast and dense floating ice far from it. In 2008, almost no ice formed except for a short period in March. During winter, fast ice , which is attached to the shoreline, develops first, rendering ports unusable without the services of icebreakers . Level ice , ice sludge , pancake ice , and rafter ice form in

He entered the Navy at just ten years old, serving aboard the frigate HMS Chatham during the American War of Independence . Chatham was employed on the blockade of Boston during the war, and 1781 fought a fierce action against the French frigate Magicienne , capturing
3382-705: The English long depended upon levies of their subjects' vessels for any major naval expeditions. Nonetheless, historians have sometimes extended the concept of an English navy and its supposed admirals and lord high admirals back as far as Alfred the Great , counting several kings as themselves admirals, along with various dukes and earls who commanded fleets at prominent engagements such as Hubert de Burgh off Sandwich in 1217 . Other lists begin their count at King Henry III 's appointment of Sir Richard de Lucy on 28 August 1223 or 29 August 1224. A similar commission

Chatham was decommissioned in 1783 at the end of the war but Hillyar remained in service, principally on the North American Station, for the next ten years. In 1793, at the outbreak of the French Revolutionary Wars , Hillyar was attached to HMS Britannia , the flagship of Lord Hotham in the Mediterranean. The following year he moved to Lord Hood 's flagship HMS Victory and participated in

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

(During this process, the short-lived post of Admiral of the Narrow Seas was used in 1412 and 1413. It was subsequently revived from 1523 to 1688.) The first royal commission as Admiral to a naval officer was granted in 1303 to Gervase Alard . By 1344, it
4094-514: 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,

The origin of the latter name is speculative and it was adopted into Slavic and Finnic languages spoken around
4450-426: 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 within today's borders of Poland , Russia and Lithuania . First mentions of amber deposits on the South Coast of the Baltic Sea date back to

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,

The ice-covered area during such a typical winter includes the Gulf of Bothnia , the Gulf of Finland , the Gulf of Riga , the archipelago west of Estonia, the Stockholm archipelago , and the Archipelago Sea southwest of Finland. The remainder of the Baltic does not freeze during
6586-411: The official ranks became admiral of the white and so forth, however each admiral's command flags were different and changed over time. The Royal Navy has had vice and rear admirals regularly appointed to the post since at least the 16th century. When in command of the fleet, the admiral would be in either the lead or the middle portion of the fleet. When the admiral commanded from the middle portion of
6675-470: The peak of the summer, with an annual average of around 9–10 °C (48–50 °F). A similar pattern can be seen in the Gotland Basin , which is located between the island of Gotland and Latvia. In the deep of these basins the temperature variations are smaller. At the bottom of the Bornholm Basin, deeper than 80 m (260 ft), the temperature typically is 1–10 °C (34–50 °F), and at
6764-514: The sea, very likely due to the role of Medieval Latin in cartography . It might be connected to the Germanic word belt , a name used for two of the Danish straits, the Belts , while others claim it to be directly derived from the source of the Germanic word, Latin balteus "belt". Adam of Bremen himself compared the sea with a belt, stating that it is so named because it stretches through
6853-471: The shore commander of a British naval port and was in charge of supplying, refitting, and maintaining the ships docked at harbour. The problem of promoting strictly by seniority was well illustrated by the case of Provo Wallis who served (including time being carried on the books while still a child) for 96 years. When he died in 1892 four admirals under him could immediately be promoted. By request of Queen Victoria , John Edmund Commerell became Admiral of
6942-657: The shores of the sea or near it usually indicate the geographical location of the sea (in Germanic languages), or its size in relation to smaller gulfs (in Old Latvian), or tribes associated with it (in Old Russian the sea was known as the Varanghian Sea). In modern languages, it is known by the equivalents of "East Sea", "West Sea", or "Baltic Sea" in different languages: At the time of the Roman Empire ,
7031-674: The southern shore . The Soviet Union gained another access to the Baltic with the Kaliningrad Oblast , that had been part of German-settled East Prussia . The Baltic states on the eastern shore were annexed by the Soviet Union. The Baltic then separated opposing military blocs: NATO and the Warsaw Pact . Neutral Sweden developed incident weapons to defend its territorial waters after the Swedish submarine incidents . This border status restricted trade and travel. It ended only after
7120-674: The subsequent invasion of Java . On 20 May 1811, he was one of the captains engaged at the Battle of Tamatave , when a French frigate squadron was defeated and two ships captured. In 1813, Hillyar was appointed Commodore of the British Pacific Squadron and was ordered to operate in the Pacific Ocean against the American whaling fleets and fur trading posts. Off Chile , he discovered the American frigate USS Essex raiding British merchant ships and tracked her to
7209-509: The west, Finland to the northeast, and the Baltic countries to the southeast. It is about 1,600 km (990 mi) long, an average of 193 km (120 mi) wide, and an average of 55 metres (180 ft) deep. The maximum depth is 459 m (1,506 ft) which is on the Swedish side of the center. The surface area is about 349,644 km (134,998 sq mi) and the volume
7298-716: The whole southern coast became German. World War I was partly fought in the Baltic Sea. After 1920 Poland was granted access to the Baltic Sea at the expense of Germany by the Polish Corridor and enlarged the port of Gdynia in rivalry with the port of the Free City of Danzig . After the Nazis' rise to power, Germany reclaimed the Memelland and after the outbreak of the Eastern Front (World War II) occupied
7387-568: Was the last European state to convert to Christianity . In the period between the 8th and 14th centuries, there was much piracy in the Baltic from the coasts of Pomerania and Prussia , and the Victual Brothers held Gotland . Starting in the 11th century, the southern and eastern shores of the Baltic were settled by migrants mainly from Germany , a movement called the Ostsiedlung ("east settling"). Other settlers were from
7476-414: Was also observed on 11 May 1799. 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
7565-467: Was covered with ice. Since 1720, the Baltic Sea has frozen over entirely 20 times, most recently in early 1987, which was the most severe winter in Scandinavia since 1720. The ice then covered 400,000 km (150,000 sq mi). During the winter of 2010–11, which was quite severe compared to those of the last decades, the maximum ice cover was 315,000 km (122,000 sq mi), which
7654-615: Was given to Sir Thomas Moulton in 1264, who held the formal title of Keeper of the Sea and the Sea Ports. On 8 March 1287, Sir William de Leybourne was specifically commissioned as the Admiral of the Seas of England ( Latin : Admirallus Maris Angliae ) and, in 1294, captain of all sailors and mariners of the king's dominions. Sir John de Botetourt served under him as warden at sea from
7743-424: Was only used as a rank at sea for a captain in charge of one or more fleets. In Elizabethan times the fleet grew large enough to be organised into squadrons . The squadron's admiral flew a red ensign , the vice admirals white , and the rear admirals blue on the aft mast of his ship. As the squadrons grew, each was eventually commanded by an admiral (with vice admirals and rear admirals commanding sections) and
7832-470: Was reached on 25 February 2011. The ice then extended from the north down to the northern tip of Gotland , with small ice-free areas on either side, and the east coast of the Baltic Sea was covered by an ice sheet about 25 to 100 km (16 to 62 mi) wide all the way to Gdańsk . This was brought about by a stagnant high-pressure area that lingered over central and northern Scandinavia from around 10 to 24 February. After this, strong southern winds pushed
7921-630: Was to make the Baltic Sea an all-Swedish sea ( Ett Svenskt innanhav ), something that was accomplished except the part between Riga in Latvia and Stettin in Pomerania. However, the Dutch dominated the Baltic trade in the seventeenth century. In the eighteenth century, Russia and Prussia became the leading powers over the sea. Sweden's defeat in the Great Northern War brought Russia to
