Aug. 17, 2007 — There was less sea ice in the Arctic on Friday than ever before on record, and the melting is continuing, the National Snow and Ice Data Center reported.

"Today is a historic day," said Mark Serreze, a senior research scientist at the center. "This is the least sea ice we've ever seen in the satellite record and we have another month left to go in the melt season this year."

Satellite measurements showed 2.02 million square miles of ice in the Arctic, falling below the Sept. 21, 2005, record minimum of 2.05 million square miles, the agency said.

Sea ice is particularly low in the East Siberian side of the Arctic and the Beaufort Sea north of Alaska, the center reported.

Ice in the Canadian Archipelago is also quite low. Along the Atlantic side of the Arctic Ocean, sea ice extent is not as unusually low, but there is still less than normal, according to the center located in Boulder, Colo.

Correspondent James Williams asks, how can caves offer climate clues?

The snow and ice center is part of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado. It receives support from NASA, the National Oceanic and Atmospheric Administration and the National Science Foundation.

Scientists began monitoring the extent of Arctic sea ice in the 1970s when satellite images became available.
