NASA Images on the Thinning Artic Sea

Quote:
Arctic sea ice is not only shrinking in coverage area; it's also thinning, according to a report and satellite images jointly released on Monday by NASA and the NASA-supported National Snow and Ice Data Center at the University of Colorado.
The Arctic basin is covered in a thick semipermanent sea ice, which is covered in thin seasonal ice caps that are built up each winter, only to melt away again each summer.
The 2009 Arctic summer-melting season is starting out with a substantial amount of thin seasonal ice and an unusually small amount of the thick sea ice, making it more vulnerable to melting, according to the NSIDC's report.
