Empirical observations were undertaken under the Circumpolar Active Layer Monitoring (CALM) program at a range of sites across the permafrost landscapes of the Yana-Indigirka and Kolyma lowlands and the Chukotka Peninsula, and supplemented with 10 years of observations from volcanic mountainous areas of the Kamchatka Peninsula. Thaw depth observations, taken using mechanical probing at the end of the thawing season, and ground temperature measurements, were analyzed with respect to air temperatures trends. The data from 24 sites (16 in the Indigirka-Kolyma region, 5 in Chukotka and 3 in Kamchatka) reveal different reactions of the active layer thickness (ALT) to recent changes in atmospheric climate. In general, there is a positive relation between ALT and summer air temperatures. Since the early 2000s positive ALT anomalies (compared with mean data from all sites) prevail in the Kolyma and Chukotka area, with only one alas site showing a negative ALT trend. The only active site in the Kamchatka Mountains shows no significant thaw depth changes over the period of observation. Two other Kamchatka sites were affected during a volcanic eruption in 2012.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2019-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83927032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Lofoten archipelago in Northern Norway is a world-class nature tourism destination, the key spawning ground for North Atlantic cod as well as a reservoir of large unexploited off-shore oil and gas deposits. We surveyed the resident Lofoten population and the larger Norwegian public to ascertain to what extent local and national perceptions of the value of selected environmental attributes and the importance of drivers of environmental change align across geographic scales. Lofoten residents and the national public both assign high value to environmental attributes, but local residents place more emphasis on harvesting marine and agricultural resources than the national public, which is more concerned with the status of individual species and conservation symbols. Our results show that the national public expresses so much interest in Lofoten that they should be considered a legitimate stakeholder in discussions about its future development paths, and while they relate to the area in a broadly similar way, there may be some specific areas of conflict that need to be considered.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75849272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This requirement poses a strain on all lifesaving appliances and causes the need for improved personal protection equipment, improved survival crafts and personal survival kits and possibly group survival kits. The paper reports on findings from search and rescue exercises north of Spitzbergen. The first exercise was carried out during late April 2016, utilizing SOLAS approved lifesaving appliances (LSA) equipment and the second exercise was conducted with improved LSA equipment during the first week of May 2017. Focus is on the ability to survive and the effectiveness of the improved LSA equipment. Furthermore, a discussion is given with respect to possible mitigation measures to ensure quick rescue to avoid the evacuated persons be exposed to an unnecessary long stay in the survival crafts. Of particular reference is the cruise industry and the industry’s efforts to provide customers with visits to even more remote cruise locations. The study indicates significant gaps between the functionality provided by the LSA equipment and the functionality required to comply with the International Maritime Organization Polar Code requirement of survival for the expected time to rescue, minimum 5 days.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76644530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of new geospatial approaches is critical to providing updated measurements of shoreline change, necessary for sustainable coastal management strategies. This research is an integration of geographic data demarcating shoreline position and its analysis to detect change using an updated modeling application – Analyzing Moving Boundaries Using R (AMBUR). Rates-of-change were evaluated over three time periods: long-term (1984–2016); and two short-term eras (1995–2005; 2006–2016). The short-term periods were specifically chosen to assess the influence of changing sea-ice regimes, increased storm intensity, and elevated air and sea-surface temperatures. Results indicate a significant alongshore increase in the rates of erosion and the spatial extent of land loss across both segments of the study area over the short-term. Mean annual rates of change increased over the most recent period (2006–2016) along the eastern segment (−0.34 m/yr) of the study area, while the western shoreline retreated at a rate of −0.24 m/yr over the same interval. These are the highest erosion rates over any time period examined in this study. As air and ocean temperature increases continue to facilitate sea ice reduction and increased permafrost thawing, shoreline erosion may be exacerbated along the Paulatuk coastline in the coming years.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2019-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73550242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found a total mean melt-lake area of 0.30 ± 0.12 km2 (±1σ), with maximum melt-lake area increasing at an average rate of 0.032 km2 d−1 across the study periods. Additionally, we note a yearly seasonal increase (∼1.8 m d−1) in the overall mean lake elevation (∼200 m per season) as well as an optimal elevation of the largest-area melt-lakes of ∼1320 ± 20 m (±1σ). We also found an increase in the maximum average melt-lake elevation (MAME) of ∼3.8 m a−1 (∼50 m). Based on data recorded at nearby automated weather stations, the mean seasonal temperature increased ∼1.6°C over the 13-year period at an average rate of 0.125°C a−1. Although temperature is a driver for meltwater production, we conclude that mechanisms related to the surface topography are more likely modulating the spatial pattern and characteristics of melt lakes in the ablation zone.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2019-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87149847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The idea of Arctic tourism has been discussed in academia for a long time, but there is no consensus on the definition of the concept. This review paper aims to discuss different perspectives on tourism in the Arctic by utilizing literature and selected examples. The outlined perspectives are spatial, produced and experienced Arctic tourism. They are interrelated and, thus, partly complementary, but they can also challenge each other. The perspectives demonstrate different ways to approach and understand various characteristics of Arctic tourism and diversity in tourism in the Arctic. All perspectives of the Arctic in tourism involve both benefits and limitations when thinking about what Arctic tourism is and what it involves. The paper concludes that there is a need to acknowledge the diversity of the Arctic as a changing idea and a geographical region in and for tourism. By acknowledging this, the Arctic would not be characterized mainly by static or external views in tourism but also by internal needs, knowledge, dynamics and concerns for sustainable tourism development in the region.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88207197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
