Above is an image of the Antarctic sea ice on October 6, 2015, the day on which it reached its annual maximum extent. The date is also displayed.
The Antarctic sea ice reached its annual maximum extent on October 6, 2015. The images shown here portray the sea ice as it was observed by the AMSR2 instrument onboard the Japanese Suzaku satellite. The opacity of the sea ice is derived from the AMSR2 sea ice concentration. The blueish white color of the sea ice is derived from the AMSR2 89 GHz brightness temperature. In some of the images, a thin red line demarks the average maximum sea ice extent from 1981 through 2010. The Landsat Image Mosaic of Antarctica is shown over the continent.
This visualization shows the growth of the Antarctic sea ice beginning on the day of its annual minimum extent, February 20, 2015, and running through the date of its annual maximum extent, October 6, 2015.
Above is an image of the Antarctic sea ice on October 6, 2015, the day on which it reached its maximum annual extent. The red line indicates the average annual maximum extent from 1981 through 2010. The date is also shown.
