Why Antarctica's Sea Ice Reversal After 2016 Has Scientists Looking Below the Surface
A new PNAS study links Antarctica’s abrupt sea ice decline after 2015 to a reversal in ocean conditions, with under-ice observations showing how trapped subsurface heat was suddenly released.
Key Takeaways
- A new PNAS study uses nearly two decades of under-ice Argo float data to explain Antarctica’s sea ice reversal.
- Surface freshening from precipitation helped sea ice expand by trapping warmer water below.
