Mangazeya ( Russian : Мангазе́я ) was a Northwest Siberian trans- Ural trade colony and later city in the 17th century. Founded in 1600 by Cossacks from Tobolsk , it was situated on the Taz River , between the lower courses of the Ob and Yenisei Rivers flowing into the Arctic Ocean . The name derives from a Nenets ethnonym Monkansi or Mongandi .
87-586: Russian settlers of the White Sea coasts of Russia ( pomors ) founded a route along the Arctic coast to Arkhangelsk to trade with Norwegian , English and Dutch merchants. Mangazeya accumulated furs and ivory (walrus tusks) around the year to be shipped out during the short Northern summer. Trade also occurred along the Siberian River Routes' Northern Route . It became "a virtual Baghdad of Siberia,
174-536: A city-state , all but independent of the Russian Empire in its wealth and utter isolation." The Northern Sea Route was forbidden in 1619 under the penalty of death and the city closed to outsiders: navigational markings were torn up, posts established to intercept anyone who might attempt to get through, and maps were falsified. The state was unable to collect taxes, and there was a fear of English trading penetration into Siberia; furthermore, "Mangazeya had aroused
261-641: 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 the land as a belt ( Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam ). He might also have been influenced by

This hinders water exchange between the White and Barents seas. The exchange is assisted by the tides , which are semidiurnal (rising twice a day), with the amplitude increasing from 1 metre on the south to 10 metres in Mezen Bay. Currents are rather weak in the open seas with the speed below 1 km/h, but they significantly strengthen in

From the 1920s, most northern Russian sea shipments diverted from the White Sea to the new port of Murmansk (officially founded in 1916), where the waters did not freeze in winter. The entire water area of the White Sea is the territorial waters of the Russian Federation. Any movement of foreign vessels on the White Sea is carried out in accordance with the legislation of the Russian Federation. The sea hosts more than 700 species of invertebrates , about 60 species of fish, and five species of marine mammals, including

Local and foreign shops and factories were established in the city at that time. The port was reinforced with a fortress which sustained a siege by the Polish-Lithuanian army in 1613. Increasing traffic overloaded the port, which relied on shallow river-waters and had limited ship-capacity. However, instead of expanding

Rivers bring annually about 215 km of fresh water, on average, mostly to the Onega, Mezen and Dvina bays. The Northern Dvina alone may contribute up to 171 km in some years, with the Mezen, Onega, Kem and Vyg rivers adding up to 38.5, 27.0, 12.5 and 11.5 km , respectively. About 40% of this volume

It 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
5655-404: 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, a related hypothesis holds that

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

The freezing period varies from year to year as shown in the satellite image to the right. The ice is not stationary, but 90% of it is floating and is continuously removed to the Barents Sea. Ice thickness is usually about 40 cm but may reach 150 cm in cold winters. In summer, surface water warms up to 15 °С in
6351-737: The shore, is the largest island in the Kandalaksha Gulf. The White Sea is a water-filled depression in the block of a continental shelf known as the Baltic Shield . Its bottom is very uneven and contains the Kandalaksha Hollow in the northwest and the Solovetsky Islands in the south. Also, the Onega Bay has many small underwater elevations. The opening and the gorlo of the sea are rather shallow, with depths about 50 metres or less. There
6438-632: 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 ,
6525-558: The south, establishing the temperature of about −15 °C (February) over most of the sea. The northern part is warmer at about −9 °C, sometimes reaching −6 °C, due to the warm air masses from the Atlantic. Arctic anticyclones, however, change winds to the northeastern ones, bringing much colder weather with temperatures of about −25 °C. Summers are cold, cloudy and relatively humid, with northeastern winds and frequent rains. Average July temperatures are 8–10 °C. Occasional southeastern winds bring warm air from Europe, raising
6612-657: 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
6699-439: The temperature to 17–19 °C and sometimes even to 30 °C. Annual precipitations increase from 282 mm in the north 529 in the south. In winter, from October–November to April–May, the sea freezes, with the average January water temperatures of −1.9 °C in the north, between −1.3 and −1.7 °С in the centre, and between −0.5 and −0.7 °С in the bays. These variations are due to the distribution of water salinity across
6786-450: 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
6873-688: 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
6960-554: 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
7047-414: 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
7134-525: Was built. 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 is situated north of Køge Bugt and connects Dragør in the south of Copenhagen to Malmö ; it
7221-461: 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
7308-561: Was escorted to Moscow to meet the Russian Tsar , Ivan IV . Returning from Russia in 1554, Chancellor brought back a detailed description of Moscow and the Russian north, which were largely unknown to Europe, as well as a letter from the Tsar expressing desire to establish trade relations with England. In 1555 Queen Mary issued a charter authorising the Muscovy Company to trade with Russia via
7395-789: Was known as New Mangazeya until the 1780s. The location of original Mangazeya and the Pomors' Northern Sea Route were forgotten until the 20th century, when archaeologists discovered remains of a wooden Kremlin and a Gostiny dvor (trading centre) on the site of Mangazeya. There is a 220 kV electrical substation owned by Gazprom with the same name nearby. 66°41′38″N 82°15′17″E / 66.6938292°N 82.2546387°E / 66.6938292; 82.2546387 White Sea The White Sea ( Russian : Белое море , romanized : Beloye more ; Karelian and Finnish : Vienanmeri , lit. 'Dvina Sea'; Nenets : Сэрако ямʼ , romanized: Serako yam )
7482-470: 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
7569-609: 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
