In this study, we propose an automated crevasse extraction framework based on Sentinel-1 SAR imagery and an improved U-Net network. The top of the glacier moves faster than the bottom due to friction against the earth. Stress in the ice caused by the glaciers movement causes crevasses to open and close. Crevasses may form on the glacier surface, on its underbelly, or on the sides. Brush them with your parka and they come tinkling down. Image from Rignot et al, 2011.

Weather over Antarctica is incredibly unpredictable, and we still cannot tell for sure how the multi-year climate cycles affect melting continent-wide. For instance, if it's known how much ice is entering a narrow valley and how fast it's moving - the volume of that ice can be worked out, giving an insight into the depth and roughness of the hidden valley floor. The new data shows a high ridge sits under these glaciers that will limit the speed at which they can drain the plateau. Only in the ocean are the.
