From #PhysicsInformedML to #MLInformedPhysics: We're excited about the "knowledge discovery" component of this project utilizing vast amount of Earth data. 🌎
There is much more out there to be discovered, as nature's imagination is far greater than that of humans. Don't stop searching.💡
In Science, researchers report a physics-informed #DeepLearning model that can predict the deformation behavior of Antarctic ice shelves, revealing complexities of the process that extend beyond the traditional understanding.

NASA Earth data + AI enable us to infer the constitutive models critical for ice dynamics. AI is useful, but no data = no discovery. Below is an example of the training data: a velocity map showing the dynamics of the Antarctic Ice Sheet. Source: #NASA.
Looking forward to learning about recent advances in #AI4Climate at the @apsphysics.bsky.social #GlobalPhysicsSummit meeting. Come check out the back-to-back focus sessions, "AI Applications in Weather and Climate I & II," on Tuesday from 9:00 AM to 1:30 PM!

A first-of-its-kind analysis revealed gaps in our understanding of how Antarctic ice is moving and melting. The findings could improve predictions about the conditions we may face in the future.
Our open-source JAX package, DIFFICE.jax (DIFFerentiable neural-network solver data assimilation of ICE shelves) is released. We are actively expanding the code's applications to other datasets and welcome collaborations!

Special thanks to Bryan Riel for writing a beautiful perspective on our paper, summarizing the key nuances of both our scientific findings and algorithmic advances.

Result: We find the constitutive law of glacial ice near grounding zones follows power laws but with varying exponents, which can impact grounding line stability. We also develop a method to detect and infer ice's anisotropic viscosity—a long-hypothesized property of glacial ice.
Method: We inject only the physics that we believe are correct, e.g. conservation of momentum, into the ML training, and leaving the uncertain physics, e.g. the constitutive law, to be determined through optimization against observations.
Details documented in our 60-page SI.
Finally published @science.org:
Can AI help yield new insights from vast amounts of Earth data?
We use large-scale data and neural nets to find the constitutive laws of glacial ice, which differ from commonly assumed forms in conventional models. #ScienceResearch
