《Satellite-observed trends in the Arctic sea ice concentration for the period 1979–2016》
Bold(italic)numbers indicate rates reaching the 99%(95%)signifi cance level.
Temporal variations in the SIC ablation trends among the Arctic sub-regions are indicated in the variations of the monthly trends(Fig.4),for which the detailed statistics are summarized in Table 1.From January to May,the variations in the monthly sea ice trends for the most parts(except the Barents Sea)are small(Fig.4),ranging from-0.40%/a(May in the Kara Sea,signifi cant at a 99%confi dence level)to0.07%/a(April in the Bering Sea,90%level).The Barents Sea shows a faster SIC decrease than the other regions,ranging between-0.69%(March,99%level)and-0.82%/a(April,99%level).After June,the negative trends of sea ice in the Beaufort Sea,Chukchi Sea,Laptev Sea and Kara Sea become distinct and commonly reach maximum declination rates in September.Beginning in October,the SIC trends in the aforementioned marginal seas shift to a slower rate of decrease.From November to December,the decreasing SIC trends in these regions are further reduced.Among the investigated areas,the Barents Sea stands out with the smallest SIC decrease occurring during the summer rather than the winter in contrast with the other areas(Fig.3).The SIC trends in the Laptev Sea and Greenland Sea are relatively stable,which is suggested by their overall weak seasonal variations(Fig.4).
