Ã…rhus Bay
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 noti ...

Aarhus Bugten
Aarhus (, , ; officially spelled Ã…rhus from 1948 until 1 January 2011) is the second-largest city in Denmark and the seat of Aarhus municipality, Aarhus Municipality. It is located on the eastern shore of Jutland in the Kattegat sea and approximately northwest of Copenhagen. Dating back to the late 8th century, Aarhus was founded as a harbour settlement at the mouth of the Aarhus River and quickly became a trade hub. The first Christian church was built here around the year 900 and later in the Viking Age the town was fortified with defensive ramparts. The Ancient See of Aarhus, bishopric of Aarhus grew steadily stronger and more prosperous, building several religious institutions in the town during the early Middle Ages. Trade continued to improve, although it was not until 1441 that Aarhus was granted market town privileges, and the population of Aarhus remained relatively stable until the 19th century. The city began to grow significantly as trade prospered in the mid-18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Environmental Research Institute Of Denmark
The National Environmental Research Institute of Denmark, abbreviated NERI, (, 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, while the secretariat and coordinatio ...

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. The term ''embayment'' is also used for , such as extinct bays or freshwater environments. 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 wit ...

Marina
A marina (from Spanish , Portuguese and Italian : "related to the sea") 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 narrowboat A narrowboat is a particular type of Barge, canal boat, built to fit the narrow History of the British canal system, locks of the United Kingdom.

Kalø Castle
Kalø Castle () 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 Eric VI of Denmark, 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, Denmark, Viborg, Bygholm Castle, Bygholm in Horsens and Ulstrup, east of Struer, Denmark, 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#Port of call, port of call, outer ringwalls and other fortifications were all built by h ...

Windmill
A windmill is a machine operated by the force of wind acting on vanes or sails to mill grain (gristmills), pump water, generate electricity, or drive other machinery. Windmills were used throughout the 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 Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines have been known earlier, the Babylonian emperor Hammurabi had used wind mill power for his irrigation project in Mesopotamia in the 17th century BC. Later, Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östlichen zur westlichen Windmühle", ''Archiv für Kulturgeschichte'', Vol. 77, Issue 1 (1995), pp. 1–30 (10f.) ...

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.

Hypoxia (environmental)
Hypoxia (''hypo'': 'below', ''oxia'': 'oxygenated') refers to low oxygen conditions. Hypoxia is problematic for air-breathing organisms, yet it is essential for many anaerobic organisms. Hypoxia applies to many situations, but usually refers to the atmosphere and natural waters. 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 training, which is a standard part of training for elite athletes. Several companies mimic hypoxia using normobaric artificial atmosphere.
