Ice - Surface melting revealed by the North Pole Environmental Observatory |
||
Sea Ice | North Pole Observations | Glaciers | Snow Cover Since 2002, the multi-agency USA-Japan joint project entitled "North Pole Environmental Observatory" (NPEO) has deployed Web Cameras along with automatic stations and instrumentation that provide valuable air/ice/ocean data sets. The summers of 2002, 2003, 2004 and 2006, as observed by the North Pole Web Cams, were very different. (see table below). The onset of melting is typically in early June, but occurred in late July in 2002, and late June in 2003 and 2004. The Web Cam images show very limited melt pond coverage in 2002, but widespread melt pond coverage in 2003 and 2004. In 2003, the melt ponds were widespread by July 4, but diminished in late July, and then reformed in mid-August. This was not observed in the other years. Freezeup began in late August in 2002, Sept 7 in 2003, and in mid-August in 2004. Find more information:
