Where’s the Ice?: Arctic Ocean Diaries No. 9

Editor’s note: Julia Whitty is on a three-week-long journey aboard the the US Coast Guard icebreaker Healy, following a team of scientists who are investigating how a changing climate might be affecting the chemistry of ocean and atmosphere in the Arctic.

The big story of this cruise is sea ice. As in, there isn’t any. At least not in our part of the Arctic Ocean. This year set a new record for lowest Arctic sea ice extant. So our odds of seeing any at this time of year weren’t good to begin with.

Still, almost everyone who set foot on the icebreaker Healy was hoping to encounter some. Sadly we haven’t seen any ice aside from what’s frozen on the decks and windows of the ship.

But the sea ice is growing fast now. The top map shows sea ice extent in this part of the Arctic on 03 October, the day I arrived in Dutch Harbor, Alaska. This analysis comes from the National Ice Center (NIC). Pink areas suggest ice cover of 80 percent or greater. Yellow marks marginal ice formation.

If you measure from due north of Point Barrow, Alaska, the ice front was roughly 440 nautical miles (506 miles / 815 kilometers) from land on 03 October.

This next map shows the sea ice extent as of yesterday, 20 Oct 2012. On that day, according to the NIC analysis, the ice front reached to within ~133 nautical miles (153 miles / 246 kilometers) of Point Barrow.

Averaged out, that out a growth rate of 18 nautical miles (20 miles / 33 kilometers) a day. Though in reality the sea ice advanced more slowly in the early part of the month and is galloping faster now.

The red track line marks Healy’s meandering for the past two-plus weeks as we visit mooring stations and CTD lines across the Beaufort and Chukchi Seas.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
