The extent of the sea ice in the Arctic has reached its annual minimum, and is now beginning to re-freeze, according to data released by the National Snow and Ice Data Center this week. This year's minimum came on September 12, and came close to, but did not exceed, last year's record minimum set on September 16, 2007. For the second straight year, the fabled Northwest Passage explored by Roald Amundsen in 1905 opened. Explorers have been attempting to sail the Northwest Passage since 1497, and 2007 and 2008 are the only known years the passage has been ice-free. In addition, 2008 saw the simultaneous opening of the Northeast Passage along the coast of Russia. This means that for the first time in recorded history, the Arctic ice cap was an island, and one could completely circumnavigate the Arctic Ocean in ice-free waters.
