RAPPORT SCIENTIFIQUE DU PROGRAMME DU PLATEAU CONTINENTAL POLAIRE 2015 1 Message du ministre Le Nord canadien est une région vaste et diversifiée, extrêmement riche en ressources naturelles et offrant à la science amples occasions de découverte. Au moyen du Programme du plateau continental polaire (PPCP), le gouvernement du Canada fournit un soutien critique à la recherche et à la découverte dans le Nord canadien. En facilitant les activités de recherche et de formation, le PPCP contribue à faire progresser la prospérité et la sécurité de l’Arctique canadien. Le travail scientifique que soutient le PPCP couvre un grand nombre de sujets, dont les changements climatiques, l’exploitation responsable des ressources, l’histoire culturelle de la région, l’intégrité du milieu naturel et les transports dans l’Arctique. Depuis 1958, le PPCP a fourni un soutien logistique à des milliers de scientifiques canadiens et de l’étranger travaillant dans une foule de domaines, de l’anthropologie à la zoologie. L’an dernier, 188 projets de recherche dans l’Arctique, comptant 1 600 participants, ont bénéficié de ce soutien logistique touchant les nolisements d’avions, l’équipement de terrain et le logement, fourni au centre de logistique du PPCP de Resolute (Qausuittuq), au Nunavut. Les chercheurs y représentaient une cinquantaine de ministères fédéraux et territoriaux, d’universités canadiennes et étrangères, et d’une foule d’organismes de recherche internationaux. J’espère que vous vous plairez à la lecture de ce rapport, qui présente les activités de recherche et de formation soutenues par le PPCP. Ce sont des activités indispensables à l’amélioration de notre connaissance du Nord canadien, indispensables aussi à la constitution d’une base de savoir et de recherche qui nous est essentielle pour que nous puissions prendre des décisions justes et fondées sur des données probantes en vue du développement économique et de la résilience du Nord.

    Frederick J. Krabbé, Last Man to See HMS Investigator Afloat, May 1854

    The Journal of the Hakluyt Society January 2017 Frederick J. Krabbé, last man to see HMS Investigator afloat, May 1854 William Barr1 and Glenn M. Stein2 Abstract Having ‘served his apprenticeship’ as Second Master on board HMS Assistance during Captain Horatio Austin’s expedition in search of the missing Franklin expedition in 1850–51, whereby he had made two quite impressive sledge trips, in the spring of 1852 Frederick John Krabbé was selected by Captain Leopold McClintock to serve under him as Master (navigation officer) on board the steam tender HMS Intrepid, part of Captain Sir Edward Belcher’s squadron, again searching for the Franklin expedition. After two winterings, the second off Cape Cockburn, southwest Bathurst Island, Krabbé was chosen by Captain Henry Kellett to lead a sledging party west to Mercy Bay, Banks Island, to check on the condition of HMS Investigator, abandoned by Commander Robert M’Clure, his officers and men, in the previous spring. Krabbé executed these orders and was thus the last person to see Investigator afloat. Since, following Belcher’s orders, Kellett had abandoned HMS Resolute and Intrepid, rather than their return journey ending near Cape Cockburn, Krabbé and his men had to continue for a further 140 nautical miles (260 km) to Beechey Island. This made the total length of their sledge trip 863½ nautical miles (1589 km), one of the longest man- hauled sledge trips in the history of the Arctic. Introduction On 22 July 2010 a party from the underwater archaeology division of Parks Canada flew into Mercy Bay in Aulavik National Park, on Banks Island, Northwest Territories – its mission to try to locate HMS Investigator, abandoned here by Commander Robert McClure in 1853.3 Two days later underwater archaeologists Ryan Harris and Jonathan Moore took to the water in a Zodiac to search the bay, towing a side-scan sonar towfish.

    Who Discovered the Northwest Passage? Janice Cavell1

    ARCTIC VOL. 71, NO.3 (SEPTEMBER 2018) P.292 – 308 https://doi.org/10.14430/arctic4733 Who Discovered the Northwest Passage? Janice Cavell1 (Received 31 January 2018; accepted in revised form 1 May 2018) ABSTRACT. In 1855 a parliamentary committee concluded that Robert McClure deserved to be rewarded as the discoverer of a Northwest Passage. Since then, various writers have put forward rival claims on behalf of Sir John Franklin, John Rae, and Roald Amundsen. This article examines the process of 19th-century European exploration in the Arctic Archipelago, the definition of discovering a passage that prevailed at the time, and the arguments for and against the various contenders. It concludes that while no one explorer was “the” discoverer, McClure’s achievement deserves reconsideration. Key words: Northwest Passage; John Franklin; Robert McClure; John Rae; Roald Amundsen RÉSUMÉ. En 1855, un comité parlementaire a conclu que Robert McClure méritait de recevoir le titre de découvreur d’un passage du Nord-Ouest. Depuis lors, diverses personnes ont avancé des prétentions rivales à l’endroit de Sir John Franklin, de John Rae et de Roald Amundsen. Cet article se penche sur l’exploration européenne de l’archipel Arctique au XIXe siècle, sur la définition de la découverte d’un passage en vigueur à l’époque, de même que sur les arguments pour et contre les divers prétendants au titre. Nous concluons en affirmant que même si aucun des explorateurs n’a été « le » découvreur, les réalisations de Robert McClure méritent d’être considérées de nouveau. Mots clés : passage du Nord-Ouest; John Franklin; Robert McClure; John Rae; Roald Amundsen Traduit pour la revue Arctic par Nicole Giguère.

    ARCTIC VOL. 53, NO. 1 (MARCH 2000) P. 88–91 ROBERT L. CHRISTIE (1926 – 1999) Dr. Robert L. Christie, geologist, naturalist, and explorer, suffered a heart attack on his beloved sailboat in the morning of 1 September 1999 and died a few hours later in hospital in Belleville, Ontario. Some weeks earlier, Bob and Audrey had sold their small farm at nearby Madoc, Ontario, and were preparing to move to Gabriola Island in British Columbia, back to Bob’s home province. Bob will be remembered for a broad range of geological achieve- ments in western and Arctic Canada, as well as in Green- land, achievements documented by nearly 100 maps and reports published in scientific journals. He will be espe- cially remembered for his loving warmth, his infectious laughter, and his limitless generosity. Bob was undoubt- edly the kindest and gentlest man I have ever known, and his family and friends were the special delights in his life. During the early sixties, Bob and I camped together for three summers in the Arctic Islands, doing fieldwork for the Geological Survey of Canada. When faced with tough conditions in the field, Bob would harden with stoic endurance. But when the sun shone on our little flycamp, he would rise to a rhapsody, and his cheerful yodel would signal that all was well in our little corner of the vast Arctic wilderness. Bob won distinction for his fieldwork, particularly in the Arctic islands, but he eschewed visible signs of pres- tige, particularly those institutionally accepted ones, like the medals that he had won, which he playfully referred to as “gongs.” He felt that his most genuine rewards came from the sense of community and solidarity developed by working closely with people whose opinions and feelings Robert L.

The task has been one of research, compilation, and abridgment, of a pleasant nature, undertaken during leisure evenings, after official hours spent in duties and undertakings of a kindred description. Numerous authorities have been consulted, and in some important instances, freely borrowed from ; amongst which, may be mentioned, former numbers of the Nautical Magazine, the Journals of the Royal Geographical Society, published accounts of voyages, personal memoirs, hydrographic works, the Naval Chronicle, Marshall, and O'Bymes Naval Biographies, &c. The object aimed at has been, to produce in a condensed form, a work, useful for hydrographic reference, and sufficiently matter of fact, for any amongst the naval surveyors of the past, who may care to take it up, for reference—and at the same time,—to handle dry dates and figures, in such a way, as to render such matter, sufficiently light and entertaining, for the present and rising generation of naval officers, who, possessing a taste for similar labours to those enumerated, may elect a hydrographic career.

    Neogene and Early Pleistocene Flora from Alaska, USA and Arctic/Subarctic Canada: New Data, Intercontinental Comparisons and Correlations

    Palaeontologia Electronica palaeo-electronica.org Neogene and early Pleistocene flora from Alaska, USA and Arctic/Subarctic Canada: New data, intercontinental comparisons and correlations T.L. Fletcher, A. Telka, N. Rybczynski, and J.V. Matthews, Jr. ABSTRACT A new correlation scheme primarily concerning macro- and meso-floral remains of bryophytes and vascular plants from 26 Neogene sites and over 50 florules in Alaska and northern Canada is presented. Flora are valuable for correlating Arctic Neogene sites, especially where absolute dating methods are not possible. These taxa clearly differentiate Neogene from Quaternary deposits in the North American Arctic. Recent age estimates provided using terrestrial cosmogenic nuclide (TCN) dating provide tie- points for these correlations and tend to confirm earlier dates achieved by relative and correlative methods. Our knowledge of North American Arctic/Subarctic palaeofloras and faunas is sufficiently detailed to allow inter-regional comparisons. This paper con- tains the first attempt to compare and contrast Neogene and early Pleistocene macro- and meso-floras from the entire circum-Arctic region. The subfossil and fossil floras are valuable for understanding the evolution of the boreal realm, from the qualitatively dif- ferent composition of the communities of the Neogene Arctic, to those of the more southerly modern boreal region. These differences may be due to the warm climate of the Neogene Arctic combined with the long dark of polar winter – a phenomenon with no modern analogue. The differences highlight the need for a comprehensive under- standing of species’ ecology to predict species ranges under near-future climate condi- tions analogous to our Neogene past. Many sites described here present rich opportunities for future cross-disciplinary study, including research related to the role of warm-climate intervals in patterning past and present Arctic ecosystems.

    SUBMISSION TO THE NUNAVUT WILDLIFE MANAGEMENT BOARD FOR Information: Decision: X Issue: Downlisting of Peary Caribou from Endangered to Threatened. Background: In October 2016 the Committee on the Status of Wildlife in Canada (COSEWIC) provided a re‐ assessment of Peary Caribou to the federal Minister of the Environment. This begins the formal listing process under the federal Species at Risk Act. Peary Caribou, which are currently listed under the federal SARA as Endangered, have been re‐assessed by COSEWIC in a lower risk category as Threatened. A recovery strategy is required for both Endangered and Threatened species. If Peary Caribou are downlisted under the federal SARA, a recovery strategy will still be required and it will not affect the current recovery strategy development process currently underway for Peary Caribou GN - Morgan Anderson Community consultations on the proposed downlisting of Peary Caribou were held with hunters and trappers organizations (HTOs) and regional wildlife boards in the range of Peary Caribou between June and August 2017. Organizations were asked to provide their formal position on the proposed downlisting and with any other comments, concerns or information that they feel should be considered. Consultation packages, in Inuktitut and English, were sent by mail and email. They included: a letter, information on the assessment and a questionnaire/response form. Follow‐up calls to the HTOs and RWBs were made on September 27, 2017. Results of Consultation: Kitikmeot Regional Wildlife Board No response
