摘要

自 1979 年以来,北极地区的变暖速度是北半球平均速度的两倍多,是全球变暖速度的近四倍。欧洲斯瓦尔巴群岛当地的变暖速度甚至更高。这种变暖正在改变陆地雪盖,而雪盖调节着地表与大气的能量交换,占北极集水区径流的大部分,同时也是大气沉积化合物(包括污染物)的瞬时储存库。为了预测这些变化对北极气候、大气、陆地生态系统和社会经济因素的影响,需要加强对北极雪盖变化的观测、了解和建模。几十年来,斯瓦尔巴群岛一直是国际极地研究中心,并得益于发达的科学基础设施。在此,我们将介绍由多学科专家共同制定的斯瓦尔巴雪地研究未来议程。我们回顾了雪研究的最新趋势,确定了主要的知识差距,对未来研究工作进行了优先排序,并建议采取支持性行动,以促进我们对冰川质量平衡、永久冻土、地表水文、陆地生态、大气污染物的循环和归宿以及雪盖遥感等方面的当前和未来雪况的了解。这篇视角文章探讨了与北极圈相关的问题,可作为其他国家或国际北极研究计划的模板。

An agenda for the future of Arctic snow research: the view from Svalbard

The Arctic region is warming at over twice the mean rate of the Northern Hemisphere and nearly four times faster than the globe since 1979. The local rate of warming is even higher in the European archipelago of Svalbard. This warming is transforming the terrestrial snow cover, which modulates surface energy exchanges with the atmosphere, accounts for most of the runoff in Arctic catchments and is also a transient reservoir of atmospherically deposited compounds, including pollutants. Improved observations, understanding and modelling of changes in Arctic snow cover are needed to anticipate the effects these changes will have on the Arctic climate, atmosphere, terrestrial ecosystems and socioeconomic factors. Svalbard has been an international hub of polar research for many decades and benefits from a well-developed science infrastructure. Here, we present an agenda for the future of snow research in Svalbard, jointly developed by a multidisciplinary community of experts. We review recent trends in snow research, identify key knowledge gaps, prioritize future research efforts and recommend supportive actions to advance our knowledge of present and future snow conditions pertaining to glacier mass balance, permafrost, surface hydrology, terrestrial ecology, the cycling and fate of atmospheric contaminants, and remote sensing of snow cover. This perspective piece addresses issues relevant to the circumpolar North and could be used as a template for other national or international Arctic research plans.

期刊介绍: Since 1982, Polar Research has been the international, peer-reviewed journal of the Norwegian Polar Institute, Norway''s central institution for research, environmental monitoring and mapping of the polar regions. Aiming to promote the exchange of scientific knowledge about the Arctic and Antarctic across disciplinary boundaries, Polar Research serves an international community of researchers and managers. As an open-access journal, Polar Research makes its contents freely available to the general public. Original primary research papers comprise the mainstay of Polar Research. Review articles, brief research notes, letters to the editor and book reviews are also included. Special issues are published from time to time. The scope of Polar Research encompasses research in all scientific disciplines relevant to the polar regions. These include, but are not limited to, the subfields of biology, ecology, geology, oceanography, glaciology and atmospheric science. Submissions from the social sciences and those focusing on polar management and policy issues are welcome. Contributions about Antarctica are particularly encouraged.
