Ref: http://www.arctic.noaa.gov/gallery_np.html
If you have broadband and can download the web-cam animations from camera 2 - the Polar Area Weather System Buoy (PAWS) - you will see a relatively large yellow object on the right of the screen. Keep an eye on the object to the left of it and further away. On May 25/26th, this suddenly starts to move around as a flaw appears between it and the rest of the instruments. The pictures from PAWS show some lowering of the snow depth in recent days as temperatures have risen to +1C but camera-1 on the Polar Ocean Profiling System Buoy (POPS-13) is showing puddling and temperatures have reached +2C. The pictures from camera-2 also show a sun-dog on April 22 and fog/ice(?)-bows on May 4 and 7. -- Graham Davis, Bracknell, Berks. E-mail: newsman-AT-scarlet-HYPHEN-jade-DOT-com Alcohol facts: Healthiest weekly amount is 21-30 units. Consume 63pw and you'll live only as long as a teetotaller. |

Hi Graham, I have been away for a couple of days, and have come back to animations, and meltponds on WebCam 2! http://www.arctic.noaa.gov/latest/noaa2.jpg The Japanese sea ice EXTENTpages also have their data in spread sheet format. http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm Using my own formula with their data I get get an estimated sea ice extent of 2 M square kms. That is obtained by assuming that the current trend for the ice to reduce in extent relative to the average of the last six years continues increase at the same rate until 1st September. I don't expect it to give an accurate value but if it is near then we will have another record melt this year, perhaps breaking the 2008 record by more than 1 M M km^2. Until now the Arctic sea ice AREA has not been at record levels for the time of year, but that now seems to be about to change. http://arctic-roos.org/observations/...i_ice_area.png So if you ignore what happened in the Spring then a big melt in the autumn seems likely. Cheers, Alastair. |

Is that the value you are estimating for the summer low?? The current record was set in 2007, not 2008 and is approx. 4.25m Km2. The value you are projecting would thus be highly unlikely, even with the present rate of loss! The IARC is located at Fairbanks, at the Univ of Alaska, BTW, though it is a joint venture with the Japanese - through a visit to Japan by a certain ex-vice president (and, for the sake of a few hanging chads, a very nearly president) of the USA -imagine being spared George Bush! I believe. |

It is from the University of Illinois arctic site here http://arctic.atmos.uiuc.edu/ so if you can open that OK, then perhaps you can navigate from there to the site I posted without a warning. It is a animation which takes a little time to load. The interesting point is that over the last couple of days the concentration has fallen dramatically. Thinking about it, it may be the concentration is unchanged, but that melt ponds have formed all over the ice. Cheers, Alastair. |

No worries opening the link Roger. |
