Is Antarctic Sea Ice Tipping Over?

We need to know sea ice thickness

​

  • Has sea ice thinned in Antarctica?
  • If so, is it a driver or responder to the low extents?

The Goal:�

To provide a winter-long characterisation of a sea ice floe in Antarctica, particularly from (a) microwave remote sensing and (b) energy balance perspectives
