  • Greenland 2019 West Greenland
    Greenland 2019 West Greenland Hunting in Greenland is the world’s largest island. Having a surface of 2.18 million, km² and only Greenland about 59,000 inhabitants it is one of the least densely populated regions in the world. The capital city is Nuuk, which has not more than 12,000 inhabitants. A large part of the country is always covered with ice, which can reach a thickness of 3,500m. About one sixth of the island is ice-free. Away from the coasts, the inland is dominated by inhospitable ice and cold deserts. Arctic climate prevails with maximum temperatures from 20 °C in the south to -5 °C in the north. In winter, lowest temperatures are around -50 °C. Hunting We are hunting in different areas winter and autumn, and in two different areas in autumn. areas: In winter, we hunt in a big area outside the concessions, its south of Kangerlussuaq, and is about 350.000 acres. Transport is easy with snowmobiles, so we can easily get around in the area. In autumn we have two concession areas (other outfitters cannot hunt there, but local hunters can go meat hunt in the areas). Both areas is unique, since area 9 is partially in the Inuit hunting World Heritage Site, and all of area 11 is in the World Heritage Site. Only our company and one other outfitter can offer hunts in this unique area where the Inuit started hunting 4000 thousand years ago, and where their old settlements and stone installation for driven hunts is still there.

  • Ilulissat Icefjord
    World Heritage Scanned Nomination File Name: 1149.pdf UNESCO Region: EUROPE AND NORTH AMERICA __________________________________________________________________________________________________ SITE NAME: Ilulissat Icefjord DATE OF INSCRIPTION: 7th July 2004 STATE PARTY: DENMARK CRITERIA: N (i) (iii) DECISION OF THE WORLD HERITAGE COMMITTEE: Excerpt from the Report of the 28th Session of the World Heritage Committee Criterion (i): The Ilulissat Icefjord is an outstanding example of a stage in the Earth’s history: the last ice age of the Quaternary Period. The ice-stream is one of the fastest (19m per day) and most active in the world. Its annual calving of over 35 cu. km 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. Criterion (iii): 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 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. BRIEF DESCRIPTIONS Located on the west coast of Greenland, 250-km north of the Arctic Circle, Greenland’s Ilulissat Icefjord (40,240-ha) is the sea mouth of Sermeq Kujalleq, one of the few glaciers through which the Greenland ice cap reaches the sea.

  • OMG GLISTIN-A 2019 Campaign Field Report
    Oceans Melting Greenland (OMG) GLISTIN-A 2019 Campaign Field Report Global sea level rise will be one of the major environmental challenges of the 21st Century. Oceans Melting Greenland (OMG) will pave the way for improved estimates of sea level rise by addressing the question: To what extent are the oceans melting Greenland’s ice from below? Over a five-year campaign, OMG will observe changing water temperatures on the continental shelf surrounding Greenland, and how marine glaciers react to the presence of warm, salty Atlantic Water. The complicated geometry of the sea floor steers currents on the shelf and often determines whether Atlantic Water can reach into the long narrow fjords and interact with the coastal glaciers. Because knowledge of these pathways is a critical component of modeling the interaction between the oceans and ice sheet, OMG will facilitate improved measurements of the shape and depth of the sea floor in key regions as well. The surveys of Greenland’s ice sheet were conducted with the GLacier and Ice Surface Topography INterferometer (GLISTIN-A), which aims to produce high spatial resolution (25 m), high-precision (< 50 cm) height maps of Greenland’s coastal glaciers, at 10 to12-km wide swaths using Ka-Band (8.4 mm wavelength) single-pass interferometry. By measuring ice surface elevation changes over several years, volume changes of marine terminating glaciers can be inferred. The GLISTIN-A radar is mounted in a pod under a Gulfstream III airplane. Operating at Ka-Band enhances interferometric accuracy, reduces penetration into the top layers of snow and firn and limits signal attenuation in the atmosphere.

We focus on cross-institutional and cross-country partnerships between preparedness institutions and companies. We elaborate on the operational crisis management of joint emergency operations including several parts of the preparedness system and resources from several countries. The project goals are: • To increase understanding of the future demands for preparedness systems in the High North including both search and rescue, oil spill recovery, fire fighting and salvage, as well as capacities fighting terror or other forms of destructive action. • To study partnerships and coordination challenges related to cross-border, multi-task emergency cooperation • To contribute with organizational tools for crisis management Project characteristics: Financial support: -Norwegian Ministry of Foreign Affairs, -the Nordland county Administration -University partners.

The breeding population of black- legged kittiwakes in the Qaanaaq area appears healthy, whereas the rest of the west coast has experienced declines, especially the north-western region (in the area from Upernavik to Kangaatsiaq). Exactly when these reductions have occurred is uncertain because of the limited survey effort in the past, but some colonies declined as far back as the mid-1900s, whereas declines of other colonies have occurred since the 1970–80s. East Greenland data from the past are few, but recent aerial surveys confirm that the abundance of breeding kittiwakes on this inaccessible coast is low.
