The impacts of the SAT on the SIC are variable depending on the area.In-phase correlations between the monthly fi elds of the SAT and SIC are generally low(-0.16)to moderate(-0.57)(Table 3) .Nevertheless,a lagged correlation analysis ahead by one to three months suggests that SAT variations can explain a fraction of the SIC changes in the Central Arctic Ocean,Barents Sea,Bering Sea,and Greenland Sea(Table 4).Recent observations have revealed thinner sea ice in the Arctic Ocean sea ice cover,which can be partly attributed to warmer surface air temperatures together with a shortened freezing period during the cold seasons.Thinner ice is usually a prerequisite during the spring for the substantial sea ice loss in the following summer.Therefore,the decreases in SIC within the Arctic Ocean shelf seas during the summer(Fig.3c)and autumn(Fig.3d)are most vulnerable to the rising surface temperatures during autumn through to spring(Fig.10d,a,and b).
