Diagnosing ice sheet grounding line stability from landform morphology

Lauren M. Simkins, Sarah L. Greenwood, and John B. Anderson

Data sets

Raw Swath Bathymetry Data from the Antarctica Ross Sea acquired during R/V Nathaniel B. Palmer expedition NBP1502 (2015) P. Bart and J. Anderson

Short summary
Using thousands of grounding line landforms in the Ross Sea, Antarctica, we observe two distinct landform types associated with contrasting styles of grounding line retreat. We characterise landform morphology, examine factors that control landform morphology and distribution, and explore drivers of grounding line (in)stability. This study highlights the importance of understanding thresholds which may destabilise a system and of controls on grounding line retreat over a range of timescales.
