Two Increases In a Row For Arctic Sea Ice Extent

Published on by sunshinehours15 Comments

Arctic Sea Ice Extent increased for the 2nd day in a row. The increase was 19,270 sq km. Minimum is getting close. Yesterday was day 250. Day 248 is the lowest value for 2013.

If day 248 turned out to be the minimum, it would be tied for third earliest with 1994. 1987’s minimum was day 245. 1997’s was 246.

Jaxa Version 2 – All The Other Graphs Compared

Published on by sunshinehours11 Comment

UPDATE: Graphs with identical axis here.

 Earlier today I noted that JAXA version 2 is out and I certainly didn’t like the new revision.

Here are all the  years/decades compared. Remember the 1980’s, 1990’s and 2000’s are averages for the whole decade. And 2002 is incomplete and starts in June.  And 2013 is incomplete because the year isn’t over.

I don’t understand how the 1980s / 1990s / 2000s “red” adjustment is so small compared to 2013 etc.

Jaxa Version 2 – Make The Low Even Lower (and the Great Big Con continues)

Published on by sunshinehours17 Comments

UPDATE: All the graphs are here.

Jaxa is one of the other sea ice monitoring agencies. They just came out with a version 2 of their data.

I thought … why not graph the difference between version 1 and version 2 for 2013.

Red = Version 2 Lower Than Version 1

Blue = Version 2 Higher Than Version 1

Guess what the following graph shows? It makes the minimum dramatically lower (400,000 sq km lower) and the maximum higher so the minimum looks even worse when graphed.

For shame.

Ice delays supply barge for Western Arctic communities

Published on by sunshinehours1Leave a comment

“Ice buildup in the Amundsen Gulf is responsible for barge delays that have many Northern coastal communities running short on supplies.

Normally, a supply barge arrives in the area in early summer to replenish stocks of fuel and other necessities in those communities. But this year, that trip is being held up by ice. As much as 30 to 40 per cent of the Arctic Ocean remains covered in ice.

“We have not seen ice with this type of coverage in quite a few years and I really don’t know how far back we might’ve seen it,” says Bill Smith, a spokesman with Northern Transportation Company Ltd., which services the communities.”

French Adventurers Blocked in the Arctic

Published on by sunshinehours13 Comments

From NorthwestPassage2013:

“Two French men, Sébastien Roubinet and Vincent Berthet , who set out on a trek to the North Pole in July in a wind catamaran, announced today that they are blocked in the Arctic. A Russian ice-breaker has been dispatched to help them.”

“The goal was to make it to Spitzberg in the Svalbard archipelago in Norway, via the North Pole and observe the state of melting ice that has gone on over the past years.

However, “Admiral Makarov”, the Russian ice-breaker will come to the rescue after receiving their distress calls.”
