ABSTRACT The first results of high spatial resolution modeling of the dispersion of atmospheric pollutant emissions from mobile sources in Antarctica are presented. 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.
摘要:本文首次提出了南极洲移动源大气污染物扩散的高空间分辨率模拟结果。本文以位于恩德比地韦切尔尼绿洲的白俄罗斯南极站为例,讨论了评估车辆对南极洲空气质量影响的备选办法。描述了输入数据的来源以及这些数据的收集和处理。在不同排放量和空间分配的平均周期和情景下,估算了地表二氧化氮(NO2)浓度、可吸入悬浮颗粒物(PM10)浓度和干大气沉降水平。如今,绿洲上的车辆数量很少。然而,根据估计,在某些地点和某些条件下,PM10和NO2的最大小时浓度可以达到空气质量指标值的可感知份额。其他一些南极站有大量车辆,评估它们对空气的影响将特别重要。提出了改进南极洲移动排放源影响定量评估的建议。

ABSTRACT Like innumerable areas worldwide, northern and Arctic areas are experiencing rapid urbanization. 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.
与世界上无数地区一样,北方和北极地区正经历着快速的城市化进程。土地通常是公有的,在同一地区有许多利益集团。在公众参与方面,不同的活动导致土地使用管理方面的具体挑战。在芬兰,从直辖市到部级都有参与的指导方针和法律规范,但参与的方式和速度因城市而异。在这篇文章中,公共参与式地理信息系统(PPGIS)的潜力在北极城市罗瓦涅米进行了研究。研究问题是:在过去和现在人口稀少的北极城市背景下,土地利用规划和决策的参与是如何实施的?受访者如何看待使用PPGIS的潜力?对PPGIS的态度是积极的,但对所有类型的参与数据,如PPGIS数据的执行被认为是模糊和薄弱的。参与的挑战与沟通不畅、信息不足和缺乏信任有关。自然价值和地方意见被认为有可能被经济价值所掩盖。

ABSTRACT How do arctic youth perceive the resilience of their communities? Many of today’s high school students in Arctic Alaska will takeup leadership roles in their communities in the next decade. The social-environmental changes these communities face are disruptive andpose challenges to local governance now and into the future. Arctic Futures Makers (AFM) was a scenarios workshop of 22 Alaska Indigenoushigh school students convened over two days in February 2016 on the resilience of the Northwest Arctic Borough’s communities in light ofclimate and development changes. 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. Three findings are significant to explain how these youth think about themselves andtheir region’s future: (1) high school students’ results are similar to those of adults in similar workshops but with important differencesrelated to what makes a community ‘livable’ (2) students were initially reticent to imagine multiple possible futures (3) students’ perceptionsof their own communities’ resilience changed after the workshop experience.
北极青年如何看待他们社区的复原力?今天阿拉斯加北极地区的许多高中生将在未来十年中担任社区的领导角色。这些社区所面临的社会环境变化是破坏性的,对现在和未来的地方治理构成了挑战。北极期货制造商(Arctic Futures Makers,简称AFM)是一个由22名阿拉斯加本土高中生参加的场景研讨会,于2016年2月召开了为期两天的会议,主题是北极西北自治市社区在气候和发展变化下的复原力。情景研讨会的范围侧重于确定学生们认为对健康和可持续社区的未来至关重要的因素。目的是了解潜在的领导者如何看待他们社区的未来,以及他们自己在北极不断变化的动态中所扮演的角色。三个发现对于解释这些年轻人如何看待自己和他们所在地区的未来具有重要意义:(1)高中生的结果与类似研讨会上的成年人相似,但在如何使社区“宜居”方面存在重要差异(2)学生最初不愿想象多种可能的未来(3)学生对自己社区弹性的看法在研讨会经历后发生了变化。

ABSTRACT The impacts of coastal erosion on municipal infrastructure and property have been widely documented within coastal Alaska. Less is known, however, about erosion-related impacts on natural resource-based land uses that contribute to the well-being of Alaska’s Native residents. 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.
在阿拉斯加沿海地区,海岸侵蚀对市政基础设施和财产的影响已被广泛记录。然而,对于以自然资源为基础的土地利用,对阿拉斯加土著居民的福祉有何影响,人们所知甚少。本研究探讨了侵蚀对阿拉斯加北坡资源型土地利用的影响。该研究采用了一种协作测绘研讨会方法,研究参与者定义了土地利用影响的主要类别,确定了风险最大的地点,并描述了侵蚀对当地和区域的主要影响。研究结果强调了与海岸侵蚀相关的三种关键类型的土地利用影响。这包括:(1)生存狩猎的中断;(2)与军用雷达资产(露天线)损坏有关的损失;(3)限制了当地公司控制土地上与油气相关的开发机会。通过详细说明当地相关的土地利用影响,研究结果有助于更好地了解气候变化如何破坏与冰冻圈相关的生态系统服务,特别是缓冲沿海风暴的文化和经济活动。研究结果加强了北极气候影响评估联合生产方法的效用和价值。通过整合当地对侵蚀风险的看法,该研究有助于形成关于北极社区气候变化风险的集体区域知识。

ABSTRACT Global climate change has the potential to cause rapid changes throughout the world, particularly in the polar regions. While much is known about attitudes towards climate change in general, relatively little is understood about individual orientations towards earth systems affected by climate change, and in particular, polar ice loss. 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.
全球气候变化有可能在全世界引起快速变化,特别是在极地地区。虽然人们对气候变化的总体态度了解很多,但对受气候变化影响的地球系统,特别是极地冰损失的个别态度了解相对较少。利用来自德国的新数据,本研究首次对知识、关注和个人意愿之间的关系进行了分析,以应对极地冰的损失。我们发现,对极地变化的了解与对极地的关注呈正相关。但是,当考虑到行为改变的意愿时,对极地地区的关注仍然是最强的预测因素,而个人自我评估的知识几乎没有直接影响。此外,对极地地区的关注仍然是一个强有力的预测愿意做出行为改变,即使在个人驾驶习惯被引入模型。因此,这一分析建立在德国对气候变化取向的新兴文献的基础上,以及对个人愿意参与行为改变以应对极地变化的机制的理解。

ABSTRACT Matching knowledge Demand, research Funding and knowledge Supply (DFS) is important in order to enhance societally and policy relevant research, target funding appropriately and enhance the connectivity between science, policy and society. 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.
匹配知识需求、研究经费和知识供给(DFS)对于加强与社会和政策相关的研究,合理定向资助,增强科学、政策和社会之间的联系至关重要。芬兰驯鹿管理的DFS领域提供了一个丰富的案例研究,可以研究相互关联和复杂的趋势,以及牧民和决策者的知识需求、部委资助和科学独立知识供应之间的关系。在芬兰驯鹿管理的案例研究中,我们在2000-2009年和2010-2018年的时间尺度上,通过10个归纳确定的主题,确定了DFS之间的匹配和不匹配。主要的发现是,在后期,DFS的匹配程度明显好于前期。为了解释这一点,我们确定并讨论了五种可选择的合法的共同创造动态,这些动态解释了DFS如何围绕芬兰的驯鹿管理组织起来。这五个动态代表了共同创造方法的变化,适合于不同的情况,这可以告知更好地匹配驯鹿管理DFS的替代方法,它们也适用于其他情况。

Medium range sea ice prediction in support of Japanese research vessel MIRAI’s expedition cruise in 2018 中期海冰预测,以支持日本研究船MIRAI在2018年的远征巡航

ABSTRACT The Japanese research vessel MIRAI sailed into the Arctic Ocean through the Bering Strait from 4 to 25 November 2018 to study the atmosphere, ocean, and sea ice of the Chukchi Sea. 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.
2018年11月4日至25日,日本科考船MIRAI通过白令海峡驶入北冰洋,研究楚科奇海的大气、海洋和海冰。初冬动力学和热力学可以导致海冰条件在短时间内发生变化。在压缩致密的冰时,可能会产生巨大的冰压。MIRAI是一艘冰强化船,必须避开厚厚的海冰和高海冰覆盖区域,因此精确的中期海冰分布预测是其安全高效航行的关键。一个高分辨率(约2.5公里)的冰-海耦合模型被用来为这次考察提供中期(10天)的预测。采用欧洲中期天气预报中心的大气模式高分辨率10天预报作为强迫数据。预报能力用冰边误差来衡量,冰边误差是预报与观测冰边之间的平均距离。采用海冰浓度为15%的阈值来指示冰缘,楚科奇海冰-海耦合模式的最大冰缘误差为16 km,表明该模式能够为船舶的运行提供足够的10天预报精度。

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}

ABSTRACT Environmental conditions in Polar Regions are becoming more dynamic due to climate change. As sea ice melts, the range of human activities in Polar Regions are projected to increase, while weather conditions are becoming more extreme and unpredictable. Provision and use of weather, water, ice and climate (WWIC) information plays a key role in ensuring that polar activities are conducted as safely as possible and can contribute to a reduction of the environmental footprint of human activities. In this article, we explore the WWIC information provider landscape in a polar context, drawing on a database we compiled to characterize the diversity of providers. The database is built on available literature and on an extensive desk-based research of WWIC information provider websites. We analyse the 374 providers categorized by (a) institutional background (public vs private), (b) the position of the provider relative to activities in the WWIC information space, and (c) the users they serve. While governmental institutions have a strong presence in information provision, new types of providers are now entering the scene. Scientific actors seem to play a substantial role as users as well as major providers of WWIC information services.
由于气候变化,极地地区的环境条件正变得更加动态。随着海冰融化,极地地区人类活动的范围预计将扩大,而天气条件将变得更加极端和不可预测。天气、水、冰和气候(WWIC)信息的提供和使用在确保极地活动尽可能安全地进行方面发挥着关键作用,并有助于减少人类活动的环境足迹。在本文中,我们将在两极上下文中探讨WWIC信息提供者的情况,并利用我们编制的数据库来描述提供者的多样性。该数据库是建立在现有文献和对WWIC信息提供者网站的广泛桌面研究基础上的。我们根据(a)机构背景(公共与私人),(b)提供商相对于WWIC信息空间活动的位置,以及(c)他们所服务的用户对374家提供商进行了分析。虽然政府机构在提供信息方面有很强的影响力,但新型提供者正在进入这一领域。科学行为者似乎作为世界信息中心信息服务的用户和主要提供者发挥了重要作用。

ABSTRACT Projections of the future size, composition, and distribution of the populations of the Arctic states and regions are useful for policy makers in planning. This paper presents and analyzes the most recent population projections done for the Arctic states and regions. Global population growth is projected to continue increasing from the current total of 7.4 billion to 10 billion in 2055. The population of the Arctic, as defined here, is projected to have little change with a projected population increase of just 1%. However, there will be considerable variation in growth rates among Arctic regions. Alaska, Yukon, Nunavut, Iceland, Troms, the Khanty-Mansiy Okrug, and Chukotka are projected to have a substantial population increase of more than 10% over the projection period. Nordland, Finnmark, North Ostrobothnia, and Nenets Autonomous Okrug are projected to have more modest growth of between 5% and 10%. Kainuu in Finland, Karelia, Komi, Arkhangel’sk, Murmansk, and Magadan in Russia are projected to have population declines of more than 5%. Common trends seen in nearly all Arctic regions in the future are aging populations, more balanced gender ratios between men and women, increased population concentration into larger urban settlements, and the depopulation of smaller settlements.
对北极国家和地区未来人口规模、组成和分布的预测对政策制定者的规划非常有用。本文介绍并分析了北极国家和地区最新的人口预测。预计全球人口增长将从目前的74亿继续增长到2055年的100亿。按照这里的定义,北极地区的人口预计变化不大,预计人口仅增长1%。然而,北极地区之间的增长率将有相当大的差异。阿拉斯加、育空、努纳武特、冰岛、特罗姆斯、汉特-曼西地区和楚科奇预计在预测期内人口将大幅增长10%以上。Nordland, Finnmark, North Ostrobothnia和涅涅茨自治区的增长率预计在5%到10%之间。芬兰的凯努、卡累利阿、科米、阿尔汉格尔斯克、摩尔曼斯克和俄罗斯的马加丹的人口预计将减少5%以上。未来几乎所有北极地区的共同趋势是人口老龄化、男女性别比例更加平衡、人口更多地集中到较大的城市定居点,以及较小的定居点人口减少。
