TAPE CONTENTS:
ITEM (1): RETREAT OF THE WESTERN ANTARCTIC ICE SHEET - The animation begins with Antarctica as it is today, then morphs to depict changes in the Antarctic ice sheet since the peak of the last ice age - nearly 20,000 years ago. The animation then morphs again to show current conditions. The West Antarctic ice sheet has lost nearly 2/3 of it's mass during this period - a volume sufficient to raise sea level 33 feet.
ITEM (2): RETREAT OF THE WESTERN ANTARCTIC ICE SHEET - CLOSE-UP VIEWS - Morph shows changes in Antarctic ice sheet from 20,000 years to present day. Various views. Cuts 1 and 2: Antarctic ice sheet changes. Cuts 3 and 4: Zoom in on Ronne ice sheet.
ITEM (3): ANTARCTIC B-ROLL
ITEM (4): INTERVIEW EXCERPTS - DR. BOB BINDSCHADLER, GLACIOLOGIST, NASA GODDARD SPACE FLIGHT CENTER
