Justin Burton and collaborators uncover the physics of ice mélange, the world's largest granular material

burtonIce melange is a granular collection of broken icebergs, that accumulates in front of tidewater glaciers.  In addition to providing a model system for studying the physics of granular materials on a grand scale, the ice melange plays an important environmental role, by acting as a “granular ice shelf,” that buttresses glacial ice and icebergs.

The work is published in the journal, Proceedings of the National Academy of Sciences:
