Bay Of Aarhus
The Bay of Aarhus, or Aarhus Bay, is a Danish waterway by Aarhus in eastern Jutland. The Bay of Aarhus is bounded by Kalø Vig in the north, Sletterhage and Helgenæs in the east, Samsø and Tunø to the south and the east Jutland coast to the west. The bay stretches over an area of and consists of a flat bassin, increasing in depth from 14 m in the west to 18 m in the east. The bay mainly exchanges water with the Kattegat through a deep trench along Helgenæs with depths to 50 m. In the bay's southern section there are a number of stony reefs including Norsminde Flak, Wulffs Flak, Mejlflak and Tunø Knob. These reefs and the islands of Tunø and Samsø, prevents an open connection with the Belt Sea. Environmental issues In 2002, the inner Danish waters suffered serious and prolonged hypoxia with the Bay of Aarhus being hit especially hard. Studies by the National Environmental Research Institute of Denmark (DMU) in November 2002 and March 2003 showed large areas with noticeabl ...

National Environmental Research Institute Of Denmark
The National Environmental Research Institute of Denmark, abbreviated NERI, ( da, Danmarks Miljøundersøgelser, abbreviated DMU) was an independent research institute under the Ministry of the Environment. It was created in 1989 by merging the existing laboratories of the Environmental Protection Agency, which covered marine, freshwater and air pollution, soil ecology and analytical chemistry, with the Danish Wildlife Research, under the Ministry of Agriculture. The laboratories were physically located on Risø, in Silkeborg and on Kalø, north of Aarhus. In 1995, Greenland Biological Research laboratory was added. The research institute was detached from the ministry in 2007 and merged into Aarhus University as a separate unit with largely unchanged tasks and responsibilities. On 1 July 2011, it was reorganized, renamed and lost status as a separate entity. The research departments were divided between the Department of Bioscience and the Department of Environmental Science, wh ...

Bays Of Denmark
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.

Port Of Aarhus
The Port of Aarhus (Danish: Aarhus Havn) is a deep-sea port located in the city of Aarhus. It is the largest container port in Denmark, handling more than 50% of country's container traffic. The Port of Aarhus shipped roughly 8.4 million metric tonnes of cargo in 2017. Geography The Port of Aarhus is located in central Aarhus at the mouth of the Aarhus River on the Bay of Aarhus in Kattegat. The port faces Helgenæs to the East, Samsø to South East and on the coast the Marselisborg Forests lies to the South and Riis Skov lies to the North. Administration The Port of Aarhus is owned and managed by Aarhus Municipality as a financially independent company. The mayor and two city council members are automatically granted seats on the board of directors after municipal elections with the mayor assuming the position of chairman. The board consists of 7 members; 3 city council members, 3 members with a background in business and 1 representative elected among the employees of the po ...

Marina
A marina (from Spanish , Portuguese and Italian : ''marina'', "coast" or "shore") is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships or cargo from freighters. The word ''marina'' may also refer to an inland wharf on a river or canal that is used exclusively by non-industrial pleasure craft such as canal narrowboats. Emplacement Marinas may be located along the banks of rivers connecting to lakes or seas and may be inland. They are also located on coastal harbors (natural or man made) or coastal lagoons, either as stand alone facilities or within a port complex. History In the 19th century, the few existing pleasure craft shared the same facilities as trading and fishing vessels. The marina appeared in the 20th century with the popularization of yachting. Facilities and services A marina may have refuelling, washing and repair facilities, marine and boat chandlers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalø Castle
Kalø Castle ( da, Kalø Slot) is a ruined castle located in eastern Jutland, in Denmark, 20 km from the city of Aarhus within Mols Bjerge National Park. History The castle was constructed in 1313 by the Danish king Erik Menved (Erik VI). It was one of at least four similar strongholds in Jutland, constructed to counter the ongoing rebellions of the Jutlandic nobility and peasantry against the Crown. The other strongholds were Borgvold in Viborg, Bygholm in Horsens and Ulstrup, east of Struer. All were built by local peasants forced labour, with the goal of breaking their rebellious spirits. Kalø Slot was raised on the small island of Kalø, connected to the mainland by a 500 m long artificial embankment, rising 1,2 m above sea level. The embankment was cobbled; deep moats were dug and earth mounds heaped around the fortress. A port of call, outer ringwalls and other fortifications were all built by hand. This was a colossal task in the early 14th century. The castle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windmill
A windmill is a structure that converts wind power into rotational energy using vanes called windmill sail, sails or blades, specifically to mill (grinding), mill grain (gristmills), but the term is also extended to windpumps, wind turbines, and other applications, in some parts of the English speaking world. The term wind engine is sometimes used to describe such devices. Windmills were used throughout the High Middle Ages, high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Culture of the Netherlands, Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines may have been known earlier, but there is no clear evidence of windmills before the 9th century. Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalø Vig
Kalø Vig (English: ''Kalø Cove'') is a cove in the north end of the Bay of Aarhus, Denmark. It stretches in a semicircle from Skæring in the North West to Kalø Castle below Rønde in the North to the peninsula Skødshoved in the East. The area around Kalø Castle became a nature preserve in 1939 and is now a part of Mols Bjerge National Park. Sight lines over the cove from Hjelmager south of Løgten are subject to conservation and preservation rules. Kalø Vig is characterized by the contrast between the modern Studstrupværket on the West side of the cove and the ruined medieval castle Kalø Slot at the bottom of the cove.

Marine Life
Marine life, sea life, or ocean life is the plants, animals and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon. Marine life in part shape and protect shorelines, and some marine organisms even help create new land (e.g. coral building reefs). Most life forms evolved initially in marine habitats. By volume, oceans provide about 90% of the living space on the planet. The earliest vertebrates appeared in the form of fish, which live exclusively in water. Some of these evolved into amphibians, which spend portions of their lives in water and portions on land. One group of amphibians evolved into reptiles and mammals and a few subsets of each returned to the ocean as sea snakes, sea turtles, seals, manatees, and whales. Plant forms such as kelp and other algae grow in the wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypoxia (environmental)
Hypoxia refers to low oxygen conditions. Normally, 20.9% of the gas in the atmosphere is oxygen. The partial pressure of oxygen in the atmosphere is 20.9% of the total barometric pressure. In water, oxygen levels are much lower, approximately 7 ppm or 0.0007% in good quality water, and fluctuate locally depending on the presence of photosynthetic organisms and relative distance to the surface (if there is more oxygen in the air, it will diffuse across the partial pressure gradient). Atmospheric hypoxia Atmospheric hypoxia occurs naturally at high altitudes. Total atmospheric pressure decreases as altitude increases, causing a lower partial pressure of oxygen, which is defined as hypobaric hypoxia. Oxygen remains at 20.9% of the total gas mixture, differing from hypoxic hypoxia, where the percentage of oxygen in the air (or blood) is decreased. This is common in the sealed burrows of some subterranean animals, such as blesmols. Atmospheric hypoxia is also the basis of altitude tra ...
