15-526: It is a bodden , a type of lagoon that occurs in northern Europe especially on the coast of Pomerania . It lies within the island of Rügen , is around 14 kilometres long, an average of six kilometres wide and is up to nine metres deep with an average depth of 5.3m. The Großer Jasmunder Bodden has an area of 58.6 square kilometres; if the Breetzer Bodden , Breeger Bodden , Lebbiner Bodden , Neuendorfer Wiek and Tetzitzer See are included

30-581: A comparatively short period between spits and offshore sandbars. These shallow glacial scoops were then subjected to extensive sedimentation during the Holocene , resulting in lakes with depths of no more than 4–6 metres. Thermal and saline stratification is extremely unstable under these conditions, and bodden have the typical dynamics of small bodies of water with a sea connection, which is a rapid filling and draining due to tidal and wind action, and inflow of fresh water. The frequent movement of water can lead to

45-549: A scouring effect, but can also with heavy pollution show a tendency toward eutrophication . Due to erosion of cliffs and sedimentary deposition, the shape of the bodden coasts remains unstable. Sudden changes have been caused by stormfloods, which repeatedly closed connections to the sea or opened new ones in the past. Bodden-type bays can be found in Mecklenburg , and in Denmark , where they are called Nor ( da ). However,

60-726: Is further connected to the Oder Lagoon by the Peenestrom , another bodden-type strait with Spandowerhagener Wiek , Krösliner See , Hohendorfer See , Krumminer Wiek and Achterwasser . The bodden are important sanctuaries for many species of birds and are especially important resting places for migratory birds like cranes and geese. This was the reason for the establishment of the Western Pomerania Lagoon Area National Park ( Nationalpark Vorpommersche Boddenlandschaft ), comprising most of

75-612: The Mastogloia Sea , a transitional stage of the Ancylus Lake . This stage and form of the body of water is named after common periwinkle ( Littorina littorea ), then a prevailing mollusc in the waters, which indicates its salinity. A transgression of the Baltic approximately 4500 BP widened its ocean link, allowing it to reach a peak of salinity during the warmer Atlantic period of European climatology. At this peak,

90-577: The Großer Jasmunder Bodden is a mix of fresh water from the streams that discharge into it and the salty waters of the Baltic and is classed as brackish water with a salt content of 0.7 to 0.8 per cent. Almost the entire shore is girt with reeds . In places the shoreline forms sea cliffs that were formed thousands of years ago by breakers in the Littorina Sea , when the islands of Wittow and Jasmund were still not linked by

105-685: The Großer Jasmunder Bodden. The north of the bodden is less divided. Only the Spykersche See near Spyker pushes east forming a small bay. By contrast the southwestern shore is more indented, with the Tetzitzer See and the Neuendorfer Wiek pushing well inland. The extreme southeastern shore of the bodden near Ralswiek is the venue for the Störtebeker Festival that takes place every summer. The water of

120-766: The Schaabe. The bodden is rich in fish and is also used for bathing and sailing. There are important harbours in Ralswiek , Polchow, Breege and St. Martin's Harbour in Sagard . The bodden has been designated an Important Bird Area (IBA) by BirdLife International because it supports large numbers of wintering waterfowl as well as breeding sandwich terns and white-tailed sea-eagles . 54°31′14″N 13°27′53″E  /  54.52056°N 13.46472°E  / 54.52056; 13.46472 Bodden Bodden are briny bodies of water often forming lagoons , along

135-568: The bodden between Darß and Rügen . Traditionally bodden have been good fishing areas, rich in mesolithic community sites, in particular the Pomeranian bodden of Rügen , Greifswald and Peenestrom . From these waters anglers regularly land 10–15 kg pike . Littorina Sea Littorina Sea (also Litorina Sea ) is a geological brackish water stage of the Baltic Sea , which existed around 7500–4000 BP and followed

150-552: The construction of an embankment that now carries the B 96 federal road and the Stralsund–Sassnitz railway . In the west at the Wittow Ferry the bodden has a narrow branch running into the lagoon of Rassower Strom and is thereby linked to the Baltic Sea . The western part of the bodden is further sub-divided into the Breetzer Bodden , Breeger Bodden and Lebbiner Bodden , which, strictly speaking, are not part of

165-642: The most typical bodden are located off the Pomeranian mainland between the mouth of the Recknitz river and the island of Usedom . Several adjacent bodden between the Fischland-Darß-Zingst peninsula, Hiddensee , the northern and western peninsulae of Rügen and the Pomeranian mainland are grouped as Bodden chains ( Boddenketten ): Another bodden is the Bay of Greifswald ( Greifswalder Bodden ),

180-701: The northern parts of which constitute the Rügischer Bodden with Schoritzer Wiek , Wreechensee , Having Inlet with Neuensiener See and Selliner See , and Hagensche Wiek . To the south, the Bay of Greifswald comprises Gristower Inwiek , Kooser See and Dänische Wieck ( Danish Bay ). The Bay of Greifswald is connected to the West Rügen bodden chain by the Strelasund , a bodden-type strait with Glewitzer Wiek , Puddeminer Wiek and Deviner See ; it

195-429: The open sea. Freshwater inflow from the mainland and saltwater inflow from the open sea, which depends on wind direction and force as well as the proximity of the bodden to the sea, result in fluctuating salt gradients and distinctive ecosystems. During the Littorina Sea transgression, an island archipelago was formed by the carving of narrow glacial basins and channels resulting from meltwater . Bodden were formed in

210-600: The southwestern shores of the Baltic Sea , primarily in Germany 's state of Mecklenburg-Vorpommern . These lagoons can be found especially around the island of Rügen , Usedom and the Fischland-Darss-Zingst peninsula. Some of them are protected reserves, forming the Western Pomerania Lagoon Area National Park . They have a distinctive geological origin and are enclosed by peninsulae, spits and islands, leaving only narrow connections to adjacent bodden or

225-508: The total area of water comes to over 94 square kilometres. The bodden is bounded to the north by the peninsulas of Wittow and Jasmund , which are linked by the narrow spit of Schaabe . To the south of the bodden is the main body of the island of Rügen, Muttland . To the east near Lietzow it is linked to the Kleiner Jasmunder Bodden by a ditch and sluice gate. The two bodden were first separated in 1869 by
