ACEAS exists to help communities prepare for climate risks emerging from East Antarctica and the Southern Ocean, with a focus on the globally significant Denman-Shackleton glacier system. We're a national research consortium, led by @utas.edu.au.

Dynamic instability of the Wilkes Subglacial Basin Ice Sheet, East Antarctica

...it contains enough ice to raise global mean sea level by 3–4 m.

Its marine-based geometry makes it a tipping risk whose temperature thresholds and timing remain poorly constrained.

The part of the Antarctic Ice Sheet within a region known as Wilkes Subglacial Basin is vulnerable to change. It holds enough ice to - on its own - raise sea levels by 3-4m. And yet it is hard to find a living scientist who has ever been there. Our new review paper talks about:

What evidence scientists do have preserved in the #geological records indicate that the basin has retreated in the past, in previous warm periods in Earth's history similar to what we may be facing in the future with a warming planet.

Below is what they are proposing ⬇️

🌊 We've released a #Saildrone into the wild!

Seven metres long, the solar-powered autonomous uncrewed vessel will circumnavigate #Antarctica to collect data on carbon dioxide absorbed by the Southern Ocean – crucial for predicting climate change. SD1092 is the first of four over the next few years.
