{"title":"“A Great Investment in Our Communities”: Strengthening Nunavut’s Whole-of-Society Search and Rescue Capabilities","authors":"P. Kikkert, P. W. Lackenbauer","doi":"10.14430/arctic73099","DOIUrl":"https://doi.org/10.14430/arctic73099","url":null,"abstract":"Community-based organizations along with territorial, provincial, and federal agencies are responsible for search and rescue (SAR) in the Canadian Arctic. In delivering response capabilities at all hours of the day and for 365 days a year, the community-based organizations face a wide array of challenges. Using the data collected through the Kitikmeot Search and Rescue Project and the Kitikmeot Roundtable on SAR, coupled with academic and non-government organization literature, this article explores the major challenges facing community SAR organizations in Nunavut and builds a case for how targeted investment can best bolster community-based capabilities. We suggest novel, practical, and holistic solutions that have been proposed by or co-devised with community partners, are rooted in the unique context of Nunavut’s communities, and are reflective of a community resilience-building approach. One set of recommendations involves strengthening current programming, including the expansion of Nunavut Emergency Management’s inReach program, continued support for the enlargement of the CCGA, streamlining the process to activate Canadian Ranger patrols, and encouraging greater cooperation in the provision of training by federal and territorial agencies. We also propose new approaches, including a whole-of-society preventative SAR program centred on educational and youth programming, the adoption of a SAR equipment usage rate model, and the launch of a Community Public Safety Officer program in Nunavut. Finally, to justify greater investment at the community level, we argue that policymakers must change how they conceptualize community-based SAR capabilities in Nunavut. An effective SAR system is about more than the ability to respond to emergency events. It is a critical enabler to broader objectives and goals prioritized in the Arctic and Northern Policy Framework and other federal, territorial, and Inuit strategies. ","PeriodicalId":55464,"journal":{"name":"Arctic","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45045751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soppela, Cara J Ocobock","doi":"10.14430/ARCTIC72667","DOIUrl":"https://doi.org/10.14430/ARCTIC72667","url":null,"abstract":"Reindeer herding involves hard physical work carried out in a cold climate under variable weather conditions. In the fall and winter, herders’ work in northern Finland includes collecting and moving reindeer herds to round-up sites, working in round-ups, slaughtering and processing meat as well as daily feeding and monitoring of the animals in the field. To study the experiences and perceptions of coping with cold among physically active herders in harsh winter conditions, we interviewed 22 herders from six herding districts of the central reindeer management area within the north boreal coniferous forest zone. We focused on behavioral and cultural strategies that accompany the physiological cold adaptations. Semi-structured interviews revealed that the main behavioral and cultural strategies used by herders to successfully carry out their duties while avoiding cold-related injury include clothing, physical activity, nutrition, and shelter as well as protecting vehicles and devices. Herders across sex, age, and herding district reported using modern layered clothing developed for extreme conditions, often combined with traditional footwear and clothes made of reindeer fur or woollen fabric. In addition, herders increase their physical activity; eat warm, energy-rich foods; make fires; stay overnight or take breaks in a house or a cabin, a car, or other protected places to reduce exposure to the harsh environment. Coping with extreme conditions not only requires flexibility, preparedness, and innovation from the herders but also thoughtful caution when approaching and managing unexpected situations. We conclude that modernization of reindeer husbandry, climate change, and rapidly increasing land use competition not only drive herders to modify their behavioral and cultural coping mechanisms for extreme weather conditions but may also create new, unexpected vulnerabilities. ","PeriodicalId":55464,"journal":{"name":"Arctic","volume":"74 1","pages":"188-205"},"PeriodicalIF":1.2,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48227627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Educators and staff went into rapid response mode to continue teaching and supporting students from a distance. Critical reflections were written by the authors to summarize their responses to teaching and learning during the early phases of the pandemic. These reflections were themed, considered individually and collectively, then analyzed and synthesized. In this paper, critical reflection is used as an educational process within the context of critical constructivism and transformative paradigms. We share how teaching during the pandemic solidified our commitment to students and cemented our critical pedagogy by thinking and acting critically to assist students with this disruption in their education. Equipped with these capabilities, educators are empowered to work with students to problem solve and transform our educative lives for a just society. An inter-professional opportunity across programs, spurred by the pandemic, meets organizational strategic directions and fosters a promising relationality. Increased territorial and local technological supports and internal professional development is needed to solidify the immense prospects for distance education as the College transitions to a polytechnic university.

Although both study regions are underlain by broadly similar geology and experience nearly identical climatic conditions, present-day water chemistry variables differed markedly between sites on the two islands. Specifically, the lakes near the Polaris Mine recorded substantially higher concentrations of zinc and lead, as well as several other heavy metals (cadmium, molybdenum, nickel, uranium, vanadium), relative to the sites on Cornwallis Island. Although the Polaris Mine closed in 2002, elevated levels of heavy metals in our 2017 survey are likely a legacy of contamination from prior operations.","PeriodicalId":55464,"journal":{"name":"Arctic","volume":"74 1","pages":"167-174"},"PeriodicalIF":1.2,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46472495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Do Wild Polar Bears (Ursus maritimus) Use Tools When Hunting Walruses (Odobenus rosmarus)?","authors":"I. Stirling, K. Laidre, E. Born","doi":"10.14430/ARCTIC72532","DOIUrl":"https://doi.org/10.14430/ARCTIC72532","url":null,"abstract":"Since the late 1700s, reports of polar bears (Ursus maritimus) using tools (i.e., pieces of ice or stones) to kill walruses (Odobenus rosmarus) have been passed on verbally to explorers and naturalists by their Inuit guides, based on local traditional ecological knowledge (TEK) as well as accounts of direct observations or interpretations of tracks in the snow made by the Inuit hunters who reported them. To assess the possibility that polar bears may occasionally use tools to hunt walruses in the wild, we summarize 1) observations described to early explorers and naturalists by Inuit hunters about polar bears using tools, 2) more recent documentation in the literature from Inuit hunters and scientists, and 3) recent observations of a polar bear in a zoo spontaneously using tools to access a novel food source. These observations and previously published experiments on brown bears (Ursus arctos) confirm that, in captivity, polar and brown bears are both capable of conceptualizing the use of a tool to obtain a food source that would otherwise not be accessible. Based on the information from all our sources, this may occasionally also have been the case in the wild. We suggest that possible tool use by polar bears in the wild is infrequent and mainly limited to hunting walruses because of their large size, difficulty to kill, and their possession of potentially lethal weapons for both their own defense and the direct attack of a predator.","PeriodicalId":55464,"journal":{"name":"Arctic","volume":"74 1","pages":"175-187"},"PeriodicalIF":1.2,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44467499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sampling was from subsistence-harvested seals from the three communities of Paulatuk (spring, summer, and autumn), Sachs Harbour (summer), and Ulukhaktok (winter), Northwest Territories. Stomach contents were separated through sieves and by hand, and taxa identified to the lowest taxonomic level possible and weighed. Stomachs were fullest (by weight and prey count) in the autumn, which suggests that foraging was most intense and successful at that time. A total of 93 prey taxa, including 17 fish and 76 invertebrate species were identified. Several fish and invertebrate species were regularly found together, the most common being Arctic cod (Boreogadus saida), sand lance (Ammodytes hexapterus), capelin (Mallotus villosus), and hyperiid amphipods (Themisto spp.). Condition measurements inferred from blubber thickness, although showing considerable variation among sites and years, had a seasonal relationship with maximal depth during the autumn and winter. Overall, the diet of ringed seals in Amundsen Gulf was broadly similar to those reported from other areas while also indicating some degree of regional specificity. When compared to the diet of ringed seals in the same area in the 1980s, the results presented here were more diverse, with new or increased numbers of subarctic species (e.g., saffron cod, Eleginus gracilis) found in the samples. This finding is a likely consequence of climate warming, as increasing numbers of subarctic species move north with warming ocean temperatures in the Arctic.","PeriodicalId":55464,"journal":{"name":"Arctic","volume":"74 1","pages":"127-138"},"PeriodicalIF":1.2,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48386213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
