Sea Ice Extent (Global Antarctic and Arctic) – Antarctic Summary 2015

As regular readers of this blog knows, there are two weird spikes in the Antarctic data that the NOAA never corrected.

I will show both sets of data: With spikes and with spikes averaged away by replacing them with the data from the day before and day after averaged.

This is the summary for 2015 if the spikes are not included:

Lowest Minimum 2.264 1997
Highest Minimum 3.692 2008
Lowest day of Minimum 43 1994
Highest day of Minimum 65 1986
Lowest Maximum 18.027 1986
Highest Maximum 20.201 2014
Lowest day of Maximum 243 1994
Highest day of Maximum 277 1988
