The wintering LIDAR physicist at Davis this year, Joseph Zagari, has taken the following movies with his time-lapse camera and will be taking more through the year. So be sure to re-visit this page as new clips will be published from time to time.
Resupply at Davis December 2004
This movie was taken of the Aurora Australis breaking through the sea-ice just before the annual 2004–05 resupply in December 2004. It was taken over a 3 hour period.

Sea ice and icebergs
Antarctica is the site of one of the most dramatic phenomena on the planet: the annual appearance and disappearance of the sea ice. See this for yourself and download QuickTime movie [525 KB]
Many people do not realise the extent to which icebergs move around.
This movie of icerbergs moving around the station at Davis was filmed over a 24 hour period. If you look carefully, you can see people moving to and fro across the sea ice. Download QuickTime [997 KB]

Disappearance of the sea ice
The freeze-thaw cycle of the sea ice around Antarctica is one of the most spectacular natural phenomena on the planet. Throughout the year, sea ice surrounds the entire Antarctic coastline, which totals 23,358 kilometers. In winter, when the sea ice reaches its maximum extent, an additional 20,000,000 square kilometer band of pack ice surrounds the continent. During the warmer summer months, this diminishes to about 4,000,000 square kilometers. For more information on sea ice, see Amazing Antarctica.
Joseph Zagari has taken this sequence of small movies of the annual disappearing of the sea ice around Davis duiring the 2004-05 summer.
