It is largest in late winter/early spring with 50,000-60,000 m3/s, but even in late summer it amounts to more than half of the winter values and contributes considerably to the interannual variability. Hence, the ice export in late summer/early autumn should not be neglected.

The correlation among single seasons is presented in Table 8.3 Sequenced seasons are weakly positively correlated with coefficients between 0.15 for spring (MAM) -summer (JJA) and 0.34 for winter (DJF) - spring (MAM). The correlation between non-sequenced seasons is very low. All seasons are significantly and highly positively correlated with the annual mean ice export. The correlation is largest in winter but still reaches 0.5 and 0.57 in summer and autumn, respectively.

The same correlation analysis is performed for ice exports of single months. Sequenced months are significantly positively correlated, whereas highest correlations occur between July-August (r = 0.41), August-September (r = 0.42) and September-October (r = 0.41) ice exports. In this time period, during summer and early autumn, wind variability is much weaker than in winter and the ice export depends largely on the amount of ice remaining from the previous winter.
