Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over .

Wedel Jarlsberg Land Dunøyane IMG 2480
Wedel is a town in the district of Pinneberg, in Schleswig-Holstein, Germany. It is situated on the right bank of the Elbe, approximately south of Elmshorn, and west of Hamburg. History Foundation and Middle Ages The first known mention of Wedel in a text is in a 1212 document naming the "brothers from Wedel" as witnesses. However, the mention is not definitive and it remains unclear whether a place of this name already existed elsewhere. Artifacts of pre- and early historical periods found here bear witness to early settlement at the site. The name means "bank of water", identifying a place where a body of water must be crossed, in this case the "Wedeler Aue", a small brook which formed an obstacle on an important local trade route. The first clear and definitive reference to Wedel is in documents of the Count of Schauenburg, a member of the Lower Saxon aristocracy that ruled the area well into the 17th century. The castle of the Schauenburgs, built in 1311 and know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornsund
Hornsund is a fjord on the western side of the southernmost tip of Spitsbergen island. The fjord's mouth faces west to the Greenland Sea, and is wide. The length is , the mean depth is , and the maximal depth is . Hornsund cuts different geological formations, from the Precambrian to the west to the upper Mesozoic to the east, and it is perpendicular to the main regional fractures of Spitsbergen. The coastline of Hornsund is diversified, with a number of bays at the mouths of mountainous glacial valleys. Some of these bays have appeared as late as the beginning of the last century due to recession of glaciers. A Polish research station has been operating there since 1957. History The English explorer Jonas Poole visited Hornsund in 1610, giving the fjord its name after his men had brought back a reindeer antler. In 1613 the first whaling ships used Hornsund, the majority of which were driven away by the English. In 1614 the fjord was ceded to the Dutch, but only for this sea ...

Wedel Jarlsberg Land
Wedel Jarlsberg Land is the land area between Van Keulenfjorden and Hornsund on the southwestern part of Spitsbergen, Svalbard Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it is about midway between the northern coast of Norway and the North Pole. The islands of the group range .... The area is largely covered with glaciers, and is completely within the Sør-Spitsbergen National Park. Named after Baron Fritz Wedel Jarlsberg (1855-1942), Norwegian minister in Paris, to whose initiative and labour it was greatly due that Norway succeeded in acquiring the sovereignty of Svalbard by a treaty signed in Paris on February 9, 1920. Until then it had been regarded as no-man's-land. The northwestern part of the area was earlier called Orvin Land. References Peninsulas of Spitsbergen {{Spitsbergen-geo-stub ...

Spitsbergen
Spitsbergen (; formerly known as West Spitsbergen; Norwegian: ''Vest Spitsbergen'' or ''Vestspitsbergen'' , also sometimes spelled Spitzbergen) is the largest and the only permanently populated island of the Svalbard archipelago in northern Norway. Constituting the westernmost bulk of the archipelago, it borders the Arctic Ocean, the Norwegian Sea, and the Greenland Sea. Spitsbergen covers an area of , making it the largest island in Norway and the 36th-largest in the world. The administrative centre is Longyearbyen. Other settlements, in addition to research outposts, are the Russian mining community of Barentsburg, the research community of Ny-Ålesund, and the mining outpost of Sveagruva. Spitsbergen was covered in of ice in 1999, which was approximately 58.5% of the island's total area. The island was first used as a whaling base in the 17th and 18th centuries, after which it was abandoned. Coal mining started at the end of the 19th century, and several permanent commun ...

Svalbard
Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it is about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and . The largest settlement is Longyearbyen. The islands were first used as a base by the whalers who sailed far north in the 17th and 18th centuries, after which they were abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities were established. The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a demilitarized zone. The Norwegian Store Norske and the Russian remain the only mining companies in place. Res ...

Nest
A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat. Nest building is driven by a biological urge known as the nesting instinct in birds and mammals. Generally each species has a distinctive style of nest. Nest complexity is roughly correlated with the level of parental care by adults. Nest building is considered a key adaptive advantage among birds, and they exhibit the most variation in their nests ranging from simple holes in the ground to elaborate communal nests hosting hundreds of individuals. Nests of prairie dogs and several social insec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barnacle Goose
The barnacle goose (''Branta leucopsis'') is a species of goose that belongs to the genus '' Branta'' of black geese, which contains species with largely black plumage, distinguishing them from the grey ''Anser'' species. Despite its superficial similarity to the brant goose, genetic analysis has shown it is an eastern derivative of the cackling goose lineage. Taxonomy and naming The barnacle goose was first classified taxonomically by Johann Matthäus Bechstein in 1803. ''Branta'' is a Latinised form of Old Norse ''Brandgás'', "burnt (black) goose" and the specific epithet is from the Ancient Greek ''leukos'' "white", and ''opsis'' "faced". The barnacle goose and the similar brant goose were previously considered one species, and were formerly believed to spawn from the goose barnacle. This gave rise to the English name of the barnacle goose and the scientific name of the brant. It is sometimes claimed that the word comes from a Celtic word for "limpet", but the sense-histor ...

Common Eider
The common eider (pronounced ) (''Somateria mollissima''), also called St. Cuthbert's duck or Cuddy's duck, is a large ( in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to . The eider's nest is built close to the sea and is lined with eiderdown, plucked from the female's breast. This soft and warm lining has long been harvested for filling pillows and quilts, but in more recent years has been largely replaced by down from domestic farm-geese and synthetic alternatives. Although eiderdown pillows or quilts are now a rarity, eiderdown harvesting continues and is sustainable, as it can be done after the ducklings leave the nest with no harm to the birds. Taxonomy The common eider was formally named by the Swedish naturalist Carl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Tern
The Arctic tern (''Sterna paradisaea'') is a tern in the family Laridae. This bird has a circumpolar breeding distribution covering the Arctic and sub-Arctic regions of Europe (as far south as Brittany), Asia, and North America (as far south as Massachusetts). The species is strongly migratory, seeing two summers each year as it migrates along a convoluted route from its northern breeding grounds to the Antarctic coast for the southern summer and back again about six months later. Recent studies have shown average annual round-trip lengths of about for birds nesting in Iceland and Greenland and about for birds nesting in the Netherlands. These are by far the longest migrations known in the animal kingdom. The Arctic tern nests once every one to three years (depending on its mating cycle). Arctic terns are medium-sized birds. They have a length of and a wingspan of . They are mainly grey and white plumaged, with a red/orange beak and feet, white forehead, a black nape and ...

Down Feather
The down of birds is a layer of fine feathers found under the tougher exterior feathers. Very young birds are clad only in down. Powder down is a specialized type of down found only in a few groups of birds. Down is a fine thermal insulator and padding, used in goods such as jackets, bedding (duvets and featherbeds), pillows and sleeping bags. The discovery of feathers trapped in ancient amber suggests that some species of dinosaur may have possessed down-like feathers. Description and etymology The word ''down'' comes from the Old Norse word ''dúnn'', which had the same meaning as its modern equivalent. The down feather is considered to be the most "straightforward" of all feather types. It has a short or vestigial rachis (shaft), few barbs, and barbules that lack hooks. There are three types of down: natal down, body down and powder down. Natal down is the layer of down feathers that cover most birds at some point in their early development.
