Underwater robot finds new circulation pattern in Antarctic ice shelf

Beyond being mere fissures in the ice, crevasses serve a crucial role in the circulation of seawater beneath Antarctic ice shelves.

This discovery is the result of research led by Cornell University, made possible by a groundbreaking expedition using an underwater robot.

The remotely operated Icefin robot’s journey up and down a crevasse within the base of the Ross Ice Shelf provided the first-ever 3D measurements of ocean conditions in proximity to the crucial grounding zone, where the ice shelf meets the coastline.

This robotic exploration unveiled a novel circulation pattern involving a jet that diverts water laterally through the crevasse, Phys.org reported.
