Episode: Could underwater tsunamis beneath Antarctica’s glaciers be speeding up ice melt
Description: A major international research mission, led by the British Antarctic Survey (BAS), is underway to investigate a newly discovered phenomenon: powerful underwater tsunamis triggered by collapsing Antarctic glaciers.
These hidden waves are created when icebergs calve (shed and collapse) from the fronts of glaciers, and they can reach several meters in height beneath the ocean surface. They create bursts of mixing that churn together different layers of seawater.
This process is now understood to be a critical driver in redistributing heat, oxygen, and nutrients throughout the polar oceans, with profound implications for marine life and global climate regulation.
Previously, ocean...
