Abstract
A time variability of ice extent for some seas is investigated using wavelet analysis. A relationship between the low-frequency changes of both the Arctic Oscillation and Antarctic Oscillation indices and sea ice extents is shown. The teleconnection analogous to the Antarctic Dipole for the ice extent in the Greenland and Bering seas is revealed.
