Storebælt
The Great Belt ( da, Storebælt, ) is a strait between the major islands of Zealand (''Sjælland'') and Funen (''Fyn'') in Denmark. It is one of the three Danish Straits. Effectively dividing Denmark in two, the Belt was served by the Great Belt ferries from the late 19th century until the islands were connected by the Great Belt Fixed Link in 1997–98. Geography The Great Belt is the largest and most important of the three Danish Straits that connect the Baltic Sea to the Kattegat strait and Atlantic Ocean. The others are the Øresund and the Little Belt straits. The Great Belt is long and wide. It flows around two major islands: Samsø in the north and Langeland to the south. At Sprogø the Great Belt divides into the East Channel and the West Channel. Both are traversed by the Great Belt Fixed Link, but a tunnel also runs under the East Channel. Geology In pre-glacial times a river, which the Baltic Sea basin then contained and which geologists call the Eridanos, must ...

Great Belt Fixed Link
The Great Belt Bridge ( da, Storebæltsbroen) or Great Belt fixed link ( da, Storebæltsforbindelsen) is a multi-element fixed link crossing the Great Belt strait between the Danish islands of Zealand and Funen. It consists of a road suspension bridge and a railway tunnel between Zealand and the small island Sprogø in the middle of the Great Belt, and a box-girder bridge for both road and rail traffic between Sprogø and Funen. The total length is . The term ''Great Belt Bridge'' commonly refers to the suspension bridge, although it may also be used to mean the box-girder bridge or the link in its entirety. Officially named the East Bridge, the suspension bridge was designed by the Danish firms COWI and Ramboll, and the architecture firm Dissing+Weitling. It has the world's sixth- longest main span (). At the time of the opening of the bridge it was the second longest, beaten by the Akashi Kaikyō Bridge opened a few months previously. The link replaced the Great Belt ferri ...

Great Belt Ferries
The Great Belt ferries ( da, Storebæltsfærgerne) were the train and car ferries operating across the Danish strait of Great Belt, between the islands of Zealand and Funen. The railway ferry link was established in 1883, while automobile-only ferries started operating in 1930. The ferry services ceased operating with the opening of the Great Belt Fixed Link, which occurred in 1997 for rail and 1998 for car traffic. Despite the popularity of the fixed link, some ferries still connect eastern and western Denmark. The company Mols-Linien continues to operate ferries between northwest Zealand and East Jutland, while the Spodsbjerg–Tårs route some 45 kilometres to the south also remains serviced by ferries. History Railway ferries had started service across another Danish strait, the much smaller Little Belt, in March 1872. A railway ferry service across the Great Belt was debated as early as 1872–75, but political unwillingness and objections from the board of Det sjællandske ...

Sprogø
Sprogø () is a small Danish island, located in the Great Belt, the strait that separates the main islands of Funen and Zealand. It is about halfway across the strait, from the Zealand shore and from the Funen shore. Although ''sprog'' is modern Danish for ''speech'', the island's name was recorded originally during the 12th century as ''Sproøe'' meaning ''scout's island'', from the old Danish verb ''spro'' (to scout). Today, the island is crossed by part of the Great Belt Fixed Link, a series of roads, bridges, and tunnels; it is connected to Funen by a road and rail bridge, and to Zealand by both a road suspension bridge and twin rail tunnels. During the construction, the island was reconfigured drastically, with land reclamation increasing its area from . There are remains of buildings on the original part of Sprogø from the beginning of the 12th century, a fortress built by order of King Valdemar the Great. During construction work, extensive archaeological investiga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-glacial Rebound
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ''ocean siphoning'' and ''continental levering'', the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.Milne, G.A., and J.X. Mitrovica (2008) ''Searching for eustasy in deglacial sea-level histories.'' Quaternary Science Reviews. 27:2292–2302. Overview During the last glacial period, much of northern E ...

Ancylus Lake
Ancylus Lake is a name given by geologists to a large freshwater lake that existed in northern Europe approximately from 9500 to 8000 years B.C being in effect one of various predecessors to the modern Baltic Sea. Origin, evolution and demise The Ancylus Lake replaced the Yoldia Sea after the latter had been severed from its saline intake across a seaway along the Central Swedish lowland, roughly between Gothenburg and Stockholm. The cutoff was the result of isostatic rise being faster than the concurrent post-glacial sea level rise. In the words of Svante Björck the Ancylus Lake "is perhaps the most enigmatic (and discussed) of the many Baltic stages". The lake's outlet and elevation relative to sea-level was for long time surrounded by controversy. It is now known that the lake was above sea level, included Lake Vänern, and drained westward through three outlets at Göta Älv, Uddevalla and Otteid. As result of the continued isostatic uplift of Sweden, the outlets in centr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gothenburg
Gothenburg (; abbreviated Gbg; sv, Göteborg ) is the second-largest city in Sweden, fifth-largest in the Nordic countries, and capital of the Västra Götaland County. It is situated by the Kattegat, on the west coast of Sweden, and has a population of approximately 590,000 in the city proper and about 1.1 million inhabitants in the metropolitan area. Gothenburg was founded as a heavily fortified, primarily Dutch, trading colony, by royal charter in 1621 by King Gustavus Adolphus. In addition to the generous privileges (e.g. tax relaxation) given to his Dutch allies from the ongoing Thirty Years' War, the king also attracted significant numbers of his German and Scottish allies to populate his only town on the western coast. At a key strategic location at the mouth of the Göta älv, where Scandinavia's largest drainage basin enters the sea, the Port of Gothenburg is now the largest port in the Nordic countries. Gothenburg is home to many students, as the city inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Level Rise
Globally, sea levels are rising due to human-caused climate change. Between 1901 and 2018, the globally averaged sea level rose by , or 1–2 mm per year on average.IPCC, 2019Summary for Policymakers InIPCC Special Report on the Ocean and Cryosphere in a Changing Climate .-O. Pörtner, D.C. Roberts, V. Masson-Delmotte, P. Zhai, M. Tignor, E. Poloczanska, K. Mintenbeck, A. Alegría, M. Nicolai, A. Okem, J. Petzold, B. Rama, N.M. Weyer (eds.) Cambridge University Press, Cambridge, UK and New York, NY, USA. https://doi.org/10.1017/9781009157964.001. This rate is accelerating, with sea levels now rising by 3.7 mm per year. Climate scientists expect further acceleration during the 21st century. Climate change heats (and therefore expands) the ocean and melts land-based ice sheets and glaciers. Between 1993 and 2018, the thermal expansion of water contributed 42% to sea level rise; melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Over the next 2 ...

Neogene
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans ('' Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North America, North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 The Atlantic in palaeoclimatology was the warmest and moistest Blytt–Sernander period, pollen zone and chronozone of Holocene northern Europe. The climate was generally warmer than today. It was preceded by the Boreal, with a climate simil ... of European climatology. At this peak, the sea bore twice the volume of water and covered 26.5% more land than it does today. As the period ended, the features of the modern coast appeared, including lagoons, sp ...
