Ice - Surface melting revealed by the North Pole Environmental Observatory
Since 2002, the multi-agency USA-Japan joint project entitled "North Pole Environmental Observatory" (NPEO) has deployed Web Cameras along with instruments that monitor air, ice and ocean conditions. The cameras and instrumentation are deployed in Spring on an ice floe drifting southward from the North Pole (drift maps are shown below). The Web Cams provide an otherwise unobtainable view of sea ice conditions throughout the Arctic summer. Animations of the images are available as YouTube videos.
In 2012, on August 26, the Arctic sea ice extent reached the lowest value observed during the satellite record. Following that low, Arctic sea ice extent continued to drop, falling below 4 million square kilometers by September 5. Compared to September conditions in the 1980's and 1990's, this represents a 45% reduction in the area of the Arctic Ocean covered by sea ice. (Reference: National Snow and Ice Data Center)...
