-How best to define ice advance and retreat in model and observational studies for the Arctic? For the Antarctic?
-What sea ice concentration threshold should be used for ice retreat/advance calculations?
-How well do models capture the timing of ice advance and ice retreat in the Arctic? In the Antarctic?
-How do ice advance and retreat impact ocean heat content, ice extent and volume?
-Can we use the timing of ice advance and retreat to improve predictability of ice extent?
-What is the role of internal variability in ice advance and retreat?
