Abstract
In their study, Andrew Hoffman from Columbia University in the USA and colleagues from the GHOST project team used satellite data in combination with image segmentation methods and crevasse modelling to quantify changes in surface crevasses in the Amundsen Sea embayment between 2015 and 2022. They find that crevasses have grown on Pine Island and Thwaites glaciers and now extend further inland than at the beginning of this time period. This expansion of crevasses is mainly linked to an accelerated loss of ice at the grounding zone, which leads to higher surface stress. These crevasses are mostly restricted to the surface firn layer and, therefore, do not yet lead to a loss of stability of the glaciers. They are, however, a signal of the accelerated mass loss that is observed from these glaciers.
期刊介绍：
Nature Climate Change is dedicated to addressing the scientific challenge of understanding Earth's changing climate and its societal implications. As a monthly journal, it publishes significant and cutting-edge research on the nature, causes, and impacts of global climate change, as well as its implications for the economy, policy, and the world at large.
The journal publishes original research spanning the natural and social sciences, synthesizing interdisciplinary research to provide a comprehensive understanding of climate change. It upholds the high standards set by all Nature-branded journals, ensuring top-tier original research through a fair and rigorous review process, broad readership access, high standards of copy editing and production, rapid publication, and independence from academic societies and other vested interests.
Nature Climate Change serves as a platform for discussion among experts, publishing opinion, analysis, and review articles. It also features Research Highlights to highlight important developments in the field and original reporting from renowned science journalists in the form of feature articles.
Topics covered in the journal include adaptation, atmospheric science, ecology, economics, energy, impacts and vulnerability, mitigation, oceanography, policy, sociology, and sustainability, among others.
