Earth's Cryosphere: Antarctica

NASA satellite imagery provides an overview of the cryosphere in the Antarctic. Learn about Antarctic features such as clouds, glaciers, ice streams, ice shelves, and icebergs. In addition, explore how rising temperatures affect the region, for example by increasing the number of meltwater ponds, which can lead to the weakening and collapse of ice shelves. Finally, see seasonal changes in sea ice and learn about their influence on ocean circulation. This video is available in both English and Spanish audio, along with corresponding closed captions.
