Abstract

Abstract Ice cliffs are features along ice sheet margins, along tropical mountain glaciers, at termini of mountain glaciers and on debris-covered glacier tongues, that have received scattered attention in literature. They cover small relative areas of glacier or margin surface respectively, but have been involved in two apparent anomalies. On the one hand, they have been identified as potential hotspots of extreme melt rates on debris-covered tongues contributing to their relatively rapid ablation, compared to the surrounding glacier surface. On the other hand, they appear where the ice margin is stable (or temporarily advancing) even under conditions of negative mass balance. In this manuscript, we recapitulate why ice cliffs remain interesting features to investigate and what we know about them so far. We conclude by suggesting to further investigate their genesis and variable morphology and their potential as windows into past climates and processes.
陡冰:冰崖研究的进展与未来挑战
摘要冰崖是沿冰原边缘、热带山地冰川、山地冰川末端和碎屑覆盖的冰川舌上的特征,在文献中得到了零星的关注。它们分别覆盖相对较小的冰川表面或边缘表面,但涉及两次明显的异常。一方面,与周围的冰川表面相比,它们已被确定为碎片覆盖舌头上极端融化速率的潜在热点,这有助于它们相对快速的消融。另一方面,它们出现在冰缘稳定(或暂时前进)的地方,即使在负质量平衡的条件下。在这篇手稿中,我们概述了为什么冰崖仍然是值得研究的有趣特征,以及到目前为止我们对它们的了解。最后,我们建议进一步研究它们的成因和变化形态,以及它们作为过去气候和过程窗口的潜力。

期刊介绍: Annals of Glaciology publishes original scientific articles and letters in selected aspects of glaciology-the study of ice. Each issue of the Annals is thematic, focussing on a specific subject. The Council of the International Glaciological Society welcomes proposals for thematic issues from the glaciological community. Once a theme is approved, the Council appoints an Associate Chief Editor and a team of Scientific Editors to handle the submission, peer review and publication of papers.
