How does Antarctic ice deform?

Area of Science:

• * Glaciology and Climate Science
• * Artificial Intelligence in Earth Observation

Background:

• * Antarctic ice shelves are critical components of the Earth's climate system, influencing sea level rise.
• * Understanding their large-scale dynamics is essential for accurate climate modeling and prediction.
• * Traditional methods for monitoring ice shelf behavior can be data-intensive and computationally demanding.

Purpose of the Study:

• * To develop and validate a novel deep-learning model for inferring large-scale Antarctic ice shelf dynamics.
