Researchers, led by British Antarctic Survey (BAS), are investigating how glacier calving around Antarctica can trigger powerful underwater tsunamis. These hidden waves cause mixing of heat, oxygen and nutrients in the ocean, which is critical for marine life and climate regulation in the region.

Too small for a tsunami and not on the kind of fault that usually causes tsunamis.

These tsunamis can be tens of metres in height & powerful enough to drag up warmer water from the depths of the ocean. This warm water speeds up the melting of the Antarctic Ice Sheet, raising global sea levels.

Take a peek behind the scenes as we send an underwater robot off on its icy mission...

You’ve heard of tsunamis before, but we bet you didn’t know they could be underwater and created by calving icebergs? 🌊

Like icebergs, much of a glacier is hidden under water so huge chunks of ice can break off, or calve. And when they do, they send shockwaves throughout the water.

Small sample size, I know, but it's interesting to me that most of the Did You Feel It responses were from inland communities. I'd think the coastal residents would be attuned to earthquakes, given the amount of preparedness for tsunamis along there.

Slightly cloudy with a chance of tsunamis

Slightly stormy with sun and tsunamis throughout the year

Developing "digital twins" for earthquakes and tsunamis like those used in weather.

Data sparseness is an issue and the need for improved understanding of the physics.
