在北极气候变暖的影响下，格陵兰岛沿着的环境正在迅速变化。为了更好地了解沿海环境的变化，我们在格陵兰岛西北部的Qaanaaq地区进行了研究，作为ArCS（北极可持续发展挑战）项目的一部分。通过实地和卫星观测，对冰盖和海洋终端出口冰川的质量损失进行了量化。在峡湾进行的测量和取样表明，冰川融水排放在海洋生态系统中发挥着重要作用。对Qaanaaq冰川溪流的洪水和附近定居点的山体滑坡进行了调查，以确定事件的驱动因素。我们的研究观察到沿海环境的快速变化，以及它们对Qaanaaq社会的重要影响。我们与当地居民举办了研讨会，以吸收当地和土著知识，并分享项目中获得的成果和数据。持续努力获得需要当地社区参与的长期观测，对于促进格陵兰的可持续未来至关重要。
Environments along the coast of Greenland are rapidly changing under the influence of a warming climate in the Arctic. To better understand the changes in the coastal environments, we performed researches in the Qaanaaq region in northwestern Greenland as a part of the ArCS (Arctic Challenge for Sustainability) Project. Mass loss of ice caps and marine-terminating outlet glaciers were quantified by field and satellite observations. Measurements and sampling in fjords revealed the important role of glacial meltwater discharge in marine ecosystems. Flooding of a glacial stream in Qaanaaq and landslides in a nearby settlement were investigated to identify the drivers of the incidents. Our study observed rapid changes in the coastal environments, and their critical impact on the society in Qaanaaq. We organized workshops with the residents to absorb local and indigenous knowledge, as well as to share the results and data obtained in the project. Continuous effort towards obtaining long-term observations requiring involvement of local communities is crucial to contribute to a sustainable future in Greenland.
