Ice animations

Introduction

Passive microwave observations of the Polar regions of the Earth provide daily information about the sea ice cover independently of cloud cover and even during the polar night. The development of the ice cover during a winter season may be illustrated by a sequence of images. MPEG animations allows us to view the images in motion, thus allowing the dynamics to be visualized in a new way.

The images are coded with the Berkeley MPEG encoder running under UNIX (AIX), and may be played back using readily available software. For information of free or shareware MPEG viewers for Machintosh, PC (Windows) and UNIX please refer to Internet viewers

Available MPEG animations

The central Greenland Sea

Note that the files are approximately 1 MByte large each, so they may take a while to download. If your MPEG viewer does not support saving the sequence, it may be a good idea to download the file to your hard disk first, and than view it later. With Netscape this is accomplished by pressing the shift key while clicking with the left mouse button on the selection.
