Options for assessing the impacts of vehicles on air quality in Antarctica are discussed using the Belarusian Antarctic Station at Vecherny Oasis, Enderby Land, as an example. Sources of input data and collection and processing of these data are described. Surface air concentrations of nitrogen dioxide (NO2), and concentrations and dry atmospheric deposition levels of respirable suspended particulate matter (PM10) are estimated for different averaging periods and scenarios of the volume and spatial allocation of emission. Nowadays, the number of vehicles in the oasis is small. However, by the estimates, the maximum hourly concentrations of PM10 and NO2 at certain locations and under certain conditions could reach perceptible share of the air quality guideline value. Some other Antarctic stations have significant vehicle population, and assessment of their air impacts will be especially important. Suggestions for improvements of the quantitative assessment of impacts of mobile emission sources in Antarctica are proposed.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":"1 1","pages":"280 - 294"},"PeriodicalIF":2.6,"publicationDate":"2020-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89738952","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 land is often publicly owned in the main, and there are many interests focusing on the same areas. Different activities lead to specific challenges in land use management in regard to public participation. There are guidelines and legal norms for participation in Finland from the municipality to the ministry level, but the style and rate of participation vary a lot from city to city. In this article the potential of public participatory geographic information systems (PPGIS) is examined in the Arctic city, Rovaniemi. The research questions are: How has participation in land use planning and decision-making been implemented in the context of sparsely populated Arctic city the past and present times? How do the interviewees see the potential of the use of PPGIS? Attitudes towards PPGIS were positive, but the implementation of all types of participation data, such as PPGIS data, was seen as vague and weak. Challenges of the participation were associated with poor communication, insufficient information, and lack of trust. Nature values and local opinions were considered to be at risk of being overshadowed by economic values.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":"106 1","pages":"295 - 312"},"PeriodicalIF":2.6,"publicationDate":"2020-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79281045","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 scope of the scenarios workshop focused on defining factors the students felt were key to the futureof healthy and sustainable communities. The intent was to understand how potential leaders perceived the futures of their communities andtheir own role in the changing dynamics of the Arctic.

This study explores erosion impacts on resource-based land uses on Alaska’s North Slope. The study utilized a collaborative mapping workshop approach, in which research participants defined major categories of land use impacts, identified locations most at risk, and described key local and regional effects of erosion. The study findings highlight three critical types of land use impacts associated with coastal erosion. These include: (1) disruption of subsistence hunting; (2) losses associated with damaged military radar assets (DEW-Line); and, (3) constrained hydrocarbon related development opportunities on land controlled by Native corporations. Through specification of locally relevant land use impacts, the study findings contribute to a better understanding of how climate change is undermining cryosphere-related ecosystem services, particularly buffering cultural and economic activity from coastal storms. The study results reinforce the utility and value of co-production approaches for Arctic climate impact assessments. Through integration of local perspectives on erosion risks, the study contributes to collective regional knowledge about climate change risks to Arctic communities.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":"26 1","pages":"259 - 279"},"PeriodicalIF":2.6,"publicationDate":"2020-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86584492","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}

Utilizing novel data from Germany, this study presents a first of its kind analysis of the relationship between knowledge, concern, and individual willingness to make behavioral changes in response to polar ice loss. We find that knowledge of changes to the polar region is positively related to concern for the polar region. But, when looking at willingness to make behavioral changes, concern for the polar regions remains the strongest predictor, while there is little direct effect of individual self-assessed knowledge. Further, concern for the polar region remains a robust predictor of willingness to make behavioral changes, even after individual driving habits are introduced to the model. As such, this analysis builds upon the emerging literature of German orientations towards climate change, as well as understanding the mechanisms by which individuals are willing to engage in behavioral changes in response to changes to the polar regions.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":"65 2 1","pages":"243 - 258"},"PeriodicalIF":2.6,"publicationDate":"2020-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90943255","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 DFS field around reindeer management in Finland offers a fertile case study to examine interconnected and complex trends as well as the relations between herders’ and policymakers’ knowledge demand, ministerial funding and independent supply of knowledge by science. We identify matches and mismatches between the DFS in a case study of reindeer management in Finland across ten inductively identified themes and in time scales of 2000–2009 and 2010–2018. The main finding was that, during the latter period, the DFS matched significantly better than in the earlier period. In order to explain this, we identify and discuss five alternative and legitimate co-creation dynamics that explain how the DFS is organizing around the reindeer management in Finland. The five dynamics represent variations in the co-creation approach, fit to varying situations, which can inform of alternative ways to better match the DFS around reindeer management, and they are also applicable in other contexts.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":"2 1","pages":"90 - 111"},"PeriodicalIF":2.6,"publicationDate":"2020-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85195818","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}

Early winter dynamics and thermodynamics can cause sea ice conditions to change over short timescales. Heavy ice pressure may build up in the compression of compact ice. MIRAI is an ice-strengthened ship that has to avoid thick sea ice and areas of high sea ice coverage, and therefore precise medium-range forecast of sea ice distribution is key to its safe and efficient navigation. A high-resolution (about 2.5 km) coupled ice–ocean model was used to produce medium-range (10-day) forecasts for the expedition. European Center for Medium-Range Weather Forecast’s atmospheric model high-resolution 10-day forecast was used as forcing data. Forecast skill is measured by ice edge error, which is the average distance between forecast and observed ice edges. Using a threshold of 15% sea ice concentration to indicate the ice edge, the maximum ice edge error in the ice–ocean coupled model in the Chukchi Sea is 16 km, indicating that the model is able to provide 10-day forecasts with sufficient accuracy for the vessel’s operation.","PeriodicalId":46164,"journal":{"name":"Polar Geography","volume":"126 1","pages":"223 - 239"},"PeriodicalIF":2.6,"publicationDate":"2020-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89175439","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}
