À propos
SituĂ© sur la cĂŽte ouest du Groenland, Ă 250 km au nord du cercle arctique, le fjord glacĂ© dâIlulissat est lâembouchure maritime de Sermeq Kujalleq, un des rares glaciers Ă travers lesquels la glace de lâinlandsis groenlandais atteint la mer. Sermeq Kujalleq est lâun des glaciers les plus rapides et les plus actifs du monde. Son vĂȘlage annuel de plus de 35 km3, soit 10 % de toute la glace de vĂȘlage (les icebergs) du Groenland, dĂ©passe celui de tous les autres glaciers du monde en dehors de lâAntarctique. ĂtudiĂ© depuis plus de 250 ans, le site a permis dâenrichir notre comprĂ©hension du changement climatique et de la glaciologie de la calotte glaciaire. Lâimmense couche de glace associĂ©e au fracas impressionnant dâune coulĂ©e de glace rapide vĂȘlant dans un fjord couvert dâicebergs crĂ©e un phĂ©nomĂšne naturel spectaculaire et grandiose.

Brief synthesis Located on the west coast of Greenland, 250 km north of the Arctic Circle, Greenlandâs Ilulissat Icefjord is a tidal fjord covered with floating brash and massive ice, as it is situated where the Sermeq Kujalleq glacier calves ice into the sea. In winter, the area is frozen solid. One of the few places where ice from the Greenland ice cap enters the sea, Sermeq Kujalleq is also one of the fastest moving (40 m per day) and most active glaciers in the world. Its annual calving of over 46 cubic kilometres of ice, i.e. 10% of all Greenland calf ice, is more than any other glacier outside Antarctica, and it is still actively eroding the fjord bed. The combination of a huge ice-sheet and the dramatic sounds of a fast-moving glacial ice-stream calving into a fjord full of icebergs make for a dramatic and awe-inspiring natural phenomenon. The Greenland ice cap is the only remnant in the Northern Hemisphere of the continental ice sheets from the Quaternary Ice Age. The oldest ice is estimated to be 250,000 years old, and provides detailed information on past climatic changes and atmospheric conditions from 250,000 to around 11,550 years ago, when climate became more stable. Studies made over the last 250 years demonstrate that during the last ice age, the climate fluctuated between extremely cold and warmer periods, while today the ice cap is being maintained by an annual accumulation of snow that matches the loss through calving and melting at the margins. This phenomenon has helped to develop our understanding of climate change and icecap glaciology. Criterion (vii): The combination of a huge ice sheet and a fast moving glacial ice-stream calving into a fjord covered by icebergs is a phenomenon only seen in Greenland and Antarctica. Ilulissat offers both scientists and visitors easy access for a close view of the calving glacier front as it cascades down from the ice sheet and into the ice-choked fjord. The wild and highly scenic combination of rock, ice and sea, along with the dramatic sounds produced by the moving ice, combine to present a memorable natural spectacle. Criterion (viii): The Ilulissat Icefjord is an outstanding example of a stage in the Earthâs history: the last ice age of the Quaternary Period. The ice-stream is one of the fastest (40 m per day) and most active in the world. Its annual calving of over 46 km3 of ice accounts for 10% of the production of all Greenland calf ice, more than any other glacier outside Antarctica. The glacier has been the object of scientific attention for 250 years and, along with its relative ease of accessibility, has significantly added to the understanding of ice-cap glaciology, climate change and related geomorphic processes. Integrity The property is of sufficient size to adequately represent the geological process of the ice fjord, i.e. the fast-moving ice-stream, the relevant portion of the inland icecap, the glacial front and the fjord. The boundaries of the property are clearly defined in relation to the logical topographic criteria of the natural watershed, and the settlements of the nearby villages of Ilimanaq and Ilulissat are excluded from the property. Along with climatic limitations and the fact that no roads exist at the site, the areaâs physical features retain a high degree of natural integrity. The property has effective legal protection and a sound planning framework, including the prohibition of any mining in the protected area. However, increased management will be required as pressures from tourism and resource harvesting continue to grow. Protection and management requirements The property is protected and conserved by an established framework of government legislation and protective designations and by local planning policies. The main legislative measure is the Greenland Parliament Act No. 29 of 18 December 2003 on nature protection. This act is the foundation framework for the protection of species, ecosystems and protected areas. Ilulissat itself is protected under the Greenland Home Rule Government Order No. 10 of 15 June 2007 on protection of Ilulissat Icefjord. The area bordering the property is further controlled by national regulations on waste disposal, use of snowmobiles, building constructions and landscape protection. Extensive hunting and fishing occurs in a portion of the property, and a special hunting law is enforced and monitored to ensure that the exploitation of biological resources in the area is sustainable. The property itself is managed cooperatively by a Board consisting of representatives from the Ministry of Environment and Nature and the Municipality of Ilulissat. A comprehensive management plan has been developed and the property will benefit from a monitoring programme. Particular attention was paid to the rapidly increasing tourism in the area, and in particular pressures emanating from cruise ships visiting the site and helicopter traffic. Regulations concerning visits to the property by boat, foot, helicopter and dog sledge; the management of waste and waste disposal; building constructions; exploitation of biological resources in the area, and protection of the cultural heritage sites within the property have been put into place. Signage and visitor infrastructure have been upgraded, and a visitor centre in the town of Ilulissat is planned. All land in the reserve is state-owned and no permanent settlements are allowed. Nearby construction is also strictly controlled. Visitor access to the area is limited by the wilderness character of the landscape, with no roads or human-made structures. Management issues such as crowding (from cruise tourism) and erosion are limited to a small area close to the town of Ilulissat. The protection of the property will be further enhanced when a planned buffer zone is adopted.
