The following diagrams show the seaice cover of the last years. Separated into the northern and southern hemisphere there will be also displayed the fraction which lies within the range of the polar night.
Since 1978 satellites are measuring the changes in seaice cover in the Arctic and Antarctic. The long-term review shows a decline of the seaice cover in the Arctic region. In the opposite case there is detectable an increase in seaice covering the Antarctic region.
