摘要

自 20 世纪 90 年代中期以来,格陵兰的冰川一直在后退、变薄和加速,格陵兰冰盖(GrIS)的质量损失现已成为全球海平面上升的最大原因。因此,使用原地或遥感方法监测冰川动力学的变化,对于增进我们对冰川学过程和冰川对气候变化的反应的了解一直至关重要。过去二十年来,技术的重大进步改善了我们观测冰川行为的方式,并有助于减少未来预测的不确定性。本综述侧重于冰川学过程现场监测方面的进展,同时也讨论了卫星遥感方面的新方法。我们进一步强调了在格陵兰冰川观测、测量和监测方面存在的差距,这些差距应加以解决,以提高我们对冰川动力学的理解,减少未来海平面上升预测的不确定性。此外,我们还审查了格陵兰开展的科学研究的协调性和包容性,并提出了可促进加强合作与共同生产的建议。

Advances in monitoring glaciological processes in Kalallit Nunaat (Greenland) over the past decades
Greenland’s glaciers have been retreating, thinning and accelerating since the mid-1990s, with the mass loss from the Greenland Ice Sheet (GrIS) now being the largest contributor to global sea level rise. Monitoring changes in glacier dynamics using in-situ or remote sensing methods has been and remains therefore crucial to improve our understanding of glaciological processes and the response of glaciers to changes in climate. Over the past two decades, significant advances in technology have provided improvements in the way we observe glacier behavior and have helped to reduce uncertainties in future projections. This review focuses on advances in in-situ monitoring of glaciological processes, but also discusses novel methods in satellite remote sensing. We further highlight gaps in observing, measuring and monitoring glaciers in Greenland, which should be addressed in order to improve our understanding of glacier dynamics and to reduce in uncertainties in future sea level rise projections. In addition, we review coordination and inclusivity of science conducted in Greenland and provide suggestion that could foster increased collaboration and co-production.
