Snow-covered mountains in background are in eastern Suess Land, with summits reaching 1874 m. Photo: Jakob Lautrup. Frontispiece: facing page In 1997 a two-year programme of regional geological mapping was begun in North-East Greenland between latitudes 72° and 75°N. Field teams were supported from a main base at Mestersvig (72°N) and a satellite tent base in Grejsdalen, Andrée Land (73°30′N). Photograph shows a view eastwards along Grejsdalen. Mountains in left background are formed by flat-lying sediments of the Neoproterozoic Eleonore Bay Supergroup, which are invaded by Caledonian granites (light rocks to the left of the prominent moraine). Summits reach 2000 m, about 1500 m above the valley floor. Photo: Jakob Lautrup. Chief editor of this series: Peter R. Dawes Scientific editors: A.K. Higgins and W. Stuart Watt Copy editor: Peter R.

  • Paleocene Alkaline Volcanism in the Nares Strait Region Related to Strike-Slip Tectonics
    Paleocene Alkaline Volcanism in the Nares Strait Region Related to Strike-slip Tectonics Solveig Estrada & Detlef Damaske Federal Institute for Geosciences and Natural Resources (BGR), Hannover, Germany ([email protected]) The tectonic development of the North Atlantic, the Labrador Sea/Baffin Bay and the Eurasian Basin of Arctic Ocean led to relative movements between the Greenland Plate and the North American Plate. There has been a debate for many years, whether the Nares Strait between northwest Greenland and Ellesmere Island marks an ancient plate boundary in terms of a left-lateral transform fault (Wegener Fault) or whether there was no movement between Greenland and Ellesmere Island at all. New data were acquired during joint German-Canadian geological field work on northeast Ellesmere Island 1998-2000 (Mayr 2008), followed in 2001 by a geoscience cruise in Nares Strait (Tessensohn et al. 2006). Indications for sinistral strike-slip movements followed by compressive tectonics were found at the western margin of northern Nares Strait (Saalmann et al. 2005). Paleogene basins on Judge Daly Promontory, northeast Ellesmere Island, are bounded by a complex pattern of strike-slip and thrust faults. The clastic sediments in the basins are rich in volcanogenic material. Volcanic pebbles within the Cape Back basin near Nares Strait are derived from lava flows and ignimbrites of a continental rift-related, strongly differentiated, highly incompatible element enriched, alkaline volcanic suite (Estrada et al. 2009). 40Ar/39Ar amphibole and alkali feldspar ages indicate that volcanism was active around 61–58 Ma and was probably contemporaneous with sedimentation within the Paleogene pull-apart basins on Judge Daly Promontory formed by sinistral strike-slip tectonics parallel to the present-day Nares Strait.

  • Chapter 8 Polar Bear Harvesting in Baffin Bay and Kane Basin: a Summary of Historical Harvest and Harvest Reporting, 1993 to 2014
    Chapter 8 SWG Final Report CHAPTER 8 POLAR BEAR HARVESTING IN BAFFIN BAY AND KANE BASIN: A SUMMARY OF HISTORICAL HARVEST AND HARVEST REPORTING, 1993 TO 2014 KEY FINDINGS Both Canada (Nunavut) and Greenland harvest from the shared subpopulations of polar • bears in Baffin Bay and Kane Basin. During 1993-2005 (i.e., before quotas were introduced in Greenland) the combined • annual harvest averaged 165 polar bears (range: 120-268) from the Baffin Bay subpopulation and 12 polar bears (range: 6-26) from Kane Basin (for several of the years, harvest reported from Kane Basin was based on an estimate). During 2006-2014 the combined annual harvest averaged 161 (range: 138-176) from • Baffin Bay and 6 (range: 3-9) polar bears from Kane Basin. Total harvest peaked between 2002 and 2005 coinciding with several events in harvest • reporting and harvest management in both Canada and Greenland. In Baffin Bay the sex ratio of the combined harvest has remained around 2:1 (male: • females) with an annual mean of 35% females amongst independent bears. In Kane Basin the sex composition of the combined harvest was 33% females overall for • the period 1993-2014. The estimated composition of the harvest since the introduction of a quota in Greenland is 44% female but the factual basis for estimation of the sex ratio in the harvest is weak. In Greenland the vast majority of bears are harvested between January and June in Baffin • Bay and Kane Basin whereas in Nunavut ca. 40% of the harvest in Baffin Bay is in the summer to fall (August – November) while bears are on or near shore.

Especially convincing is evidence, presented by DAMASKE & OAKEY (2006), that at least one basic dyke of Neoproterozoic age extends across Smith Sound from Inglefield Land to inshore eastern Ellesmere Island without any recognizable strike slip offset. INTRODUCTION These results confirm that no major sinistral fault exists in southern Nares Strait. It is apparent to both earth scientists and the general public To account for the absence of a Wegener Fault in most parts of Nares Strait, that the shape of both coastlines and continental margins of the present paper would locate the late Paleocene-Eocene Greenland plate boundary on an interconnected system of faults that are 1) traced through western Greenland and eastern Arctic Canada provide for a Jones Sound in the south, 2) lie between the Eurekan Orogen and the Precam- satisfactory restoration of the opposing lands.

  • 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.

  • Faroe Islands and Greenland 2008
    N O R D I C M E D I A T R E N D S 10 Media and Communication Statistics Faroe Islands and Greenland 2008 Compiled by Ragnar Karlsson NORDICOM UNIVERSITY OF GOTHENBURG 2008 NORDICOM’s activities are based on broad and extensive network of contacts and collaboration with members of the research community, media companies, politicians, regulators, teachers, librarians, and so forth, around the world. The activities at Nordicom are characterized by three main working areas. Media and Communication Research Findings in the Nordic Countries Nordicom publishes a Nordic journal, Nordicom Information, and an English language journal, Nordicom Review (refereed), as well as anthologies and other reports in both Nordic and English langu- ages. Different research databases concerning, among other things, scientific literature and ongoing research are updated continuously and are available on the Internet. Nordicom has the character of a hub of Nordic cooperation in media research. Making Nordic research in the field of mass communication and media studies known to colleagues and others outside the region, and weaving and supporting networks of collaboration between the Nordic research communities and colleagues abroad are two prime facets of the Nordicom work. The documentation services are based on work performed in national documentation centres at- tached to the universities in Aarhus, Denmark; Tampere, Finland; Reykjavik, Iceland; Bergen, Norway; and Göteborg, Sweden. Trends and Developments in the Media Sectors in the Nordic Countries Nordicom compiles and collates media statistics for the whole of the Nordic region. The statistics, to- gether with qualified analyses, are published in the series, Nordic Media Trends, and on the homepage.
