a) Sea ice persistence (days/year) by year for the northern Bering Sea and Chukchi Sea, b) Sea ice persistence anomalies for 2012 (15 September 2011–14 September 2012), c) Sea ice persistence anomalies for 2014 (15 September 2013–14 September 2014). Made with Natural Earth coastline data. Sea ice persistence anomalies initiate in September for the preceding calendar year to include sea ice formation and retreat in one sea ice season and were compared to a 1980/1981-2009/2010 base period.
