Focusing on Envisats Radar Altimeter (RA-2) and Along Track Scanning Radiometer (AATSR)insturments this programme explains how Envisat will be used to gather data on the Antarctic. In providing this data Envisat will help scientists answer the question on whether the shrinking of the Southern Polar Ice cap will effect global sea levels.
The 5-minute A-roll contains split audio with an English guide track and is complemented by a B-roll with international sound only, including sound bites with scientific experts.

...for if even a small fraction of this ice should melt the gobal sea level would rise by perhaps as much as 5 metres.

This is why satellites like ESA's ERS have been monitoring the Antarctic Ice Sheet for more than a decade now. WIth the second ERS satellite nearing the end of its five year mission the launch of ENVISAT will provide a host of new and updated instrumentation - an evolutionalry path to increasing our knowledge of global change.
