Very strange indeed. Is the situation south of Victoria Island also odd?
Commented Oct 7, 2018 on Freezing season has started, or has it? at Arctic Sea Ice
Freezing season has started, or has it?
We tend to focus on the end of the melting season, also known as the minimum, because that's when the ice covers the least amount of water. That's all fine and dandy, but of course, it's just an arbitrary measuring point. For instance, this year's minimum for the JAXA sea ice extent data set was...
" in summer they could sail in the melt ponds"
That, is scary. Very scary.

Circumnavigating Greenland
A quite spectacular event took place during the past two weeks, and if it had continued for a while longer, I'm sure it would've been reported widely. It's something I've semi-jokingly alluded to when setting up this blog back in 2010, in my third blog post called Dire Straits, and a partial ans...
Has anyone else notices the polyannas (or worse open water) between Greenland and Ellesmere Island and between Greenland and the central Arctic Ice pack.
Any ideas about why these are developing or if they are real

As we approach the final stretch...
For years we've talked about one of the most fascinating phenomena of Arctic sea ice loss as it progresses from year to year: The moment when the ice disappears regardless of the weather. We've seen some of that, back in July 2012, when extent and area numbers kept going down steadily, even tho...
Wouldn't get too excited about naming the storm. After all Sandy was not a hurricane at landfall.

2016 Arctic cyclone, update 3
Two days have passed since the previous update, and in those two days the storm re-intensified, bottomed out at 971 hPa (slightly higher than the first lowest central pressure of 968 hPa), as can be seen on the image on the left, provided by Environment Canada. It quickly weakened after that, bu...
How much Ice is going to b left below 75 N (Eli says a flat zero which is scary). How much below 80 N. Will it be possible to sail blue water to closer than 85N to the pole (looks like it) One of the problems with sea ice charts is that they show ice you know in March is going to vanish in August, e.g. Hudson's Bay.

PIOMAS August 2016
Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: With a slightly above average drop during July 2016 is maintaining its position relative to other yea...
Looking at AMSR2 the question is how much ice will be left south of 75N in early August and there may not be any. Scary.

ASI 2016 update 4: breaking point
During the melting season I'm writing (bi-)weekly updates on the current situation with regards to Arctic sea ice (ASI). Because of issues with data based on the SSMIS sensor aboard DMSP satellites, I mainly focus on higher-resolution AMSR2 data from the Japan Aerospace Exploration Agency (JAXA...
It really depends on the degree to which polar stratospheric clouds have formed and to an extent on how long they have been there. It is not clear how much time is needed for denitirification via ClONO2 deposition. Since it is only a month or so to first light and Dec-Jan were quite warm, a cold stratosphere by itself may not be enough

Potential record ozone hole over the Arctic
The ozone hole as a phenomenon is mostly associated with the Antarctic, but the Arctic also has one, much more variable in size than its Southern Hemisphere sibling. This winter the stratosphere over the Arctic has been extremely cold, causing a lot of ozone to be destroyed. If things keep up, ...
What is going on with Cryosphere Today?? It show a huge increase in sea ice area today

2015 SIPN Sea Ice Outlook: August report
The third and last Sea Ice Outlook of this year has been published. The SIO is organized by the Sea Ice Prediction Network (as part of the Arctic research program 'Study of Environmental Arctic Change', or SEARCH), and is a compilation of projections for the September 2015 Arctic sea ice extent...
Navegante: Hurricane Sandy took a sharp left turn towards NY/NJ.
FWIW, Eli has always thought that the amount of ice coverage outside of 80 N is a good indicator of the state of the ice.

ASI 2015 update 6: one more high
During the melting season I'm writing (bi-)weekly updates on the current situation with regards to Arctic sea ice (ASI). Central to these updates are the daily Cryosphere Today sea ice area (SIA) and IJIS sea ice extent (SIE) numbers, which I compare to data from the 2005-2014 period (NSIDC has...
Thanks for the update
