Unmanned Submersible Unveils Hidden Antarctic Ice Shelf Features

First detailed maps of Dotson Ice Shelf reveal complex formations and critical melt patterns, enhancing sea level rise predictions.

Researchers used an autonomous underwater vehicle to map the underside of the Dotson Ice Shelf in West Antarctica.
The submersible, named Ran, captured high-resolution images showing unexpected peaks, valleys, and sand dune-like formations.
Data indicates that underwater currents and Earth's rotation significantly influence the ice shelf's melting patterns.
The findings challenge current models and highlight the need for improved predictions of future ice melt rates.
Ran disappeared during a follow-up mission, underscoring the challenging conditions of Antarctic research.
