For those on NARWHAL; or those just interested in ships, shipwrecks, and ice in the Arctic; I have been following a fascinating blog:
Northwest Passage Blogspot It has lots of links to weather and ice data and also to various groups transiting the Northwest Passage this year.
Another great site for those interested in either Arctic or Antarctic ice conditions is
Cryosphere Today This is a good site for historical comparisons of ice conditions at both polls. You can also get ice conditions in various areas of the Arctic Ocean.
