Eureka: We know they got supplied last year? But this? Any the ice has come back fast last couple of days.
You can't go off visual satellites as different ice has different reflectivity. Never been a clear passage from the charts.

Never been a clear passage from the charts. I cant get a definative answer yet. But: Converted Russian ice breaker cruise ships like Capitan Khlebnikov leased to Quark Expeditions were going past Eureka to Tanquary Fiord in recent years and it can go thru 3m of ice. At least two canadian icebreakers were at eureka last year going by the videos on utube. Its not like it would be mission impossible. Swedish and Russian boats can get to the pole - the Swedish boat seems to eat the ice and spit it out the back rather than ride over it. The Russian boat is nuclear powered and takes cruises with Quark. However the ice is thicker this year than last year for that route i agree. Going by the poor Satellite image the ice is broken and you can see that sort of thing from a good satellite image - which we dont have.

Finally its September. Sometime soon the ice down curve should begin the ramp up. When ? Early or late this month ? I think it is just days away and definitely before the Equinox.

I emailed the Canadian Coast Guard, and have been assured that the resupply mission(s?) to Eureka have recently been completed as per usual. Interestingly enough, I was asked in return why I had asked the question in the first place. The person who gave me the reply was obviously non-plussed as to why anyone in their right mind was wondering at all. I explained that there had been speculation on this blog as to whether the resupply could take place at all.

The Des Groseilliers arrived on the morning of 25 August, and the Terry Fox sometime later. They were both gone by the 29th

My gues is that it will go up and down for the next ten days and by end of september the sea ice extend will climb up sharply

Re resupply to Resolute- Not easy information to find, so thanks for that. I'd love to see the ship's logs of the journey for the last few years for comparison. (Heck, I'd love to be on the ship!)
The next question that has been at the back of my mind is:
What is the effect on the Ice extent of a dozen or so large Icebreakers smashing up the ice? These monsters smash channels through the ice some 10's of metres wide and 1000's of kms long.
The disturbance of the ice pack will both increase melting and enable the ice to move more freely out of the arctic.
The increase in use of Icebreakers has been (a) Ecotourism! and (b) the grab for resources and sovereignty by Russia, Canada, USA, Norway etc.
There have new icebreakers added in recent years.
Maybe the decline in ice is indeed the result of Man's activity!

Compared to the forces of nature a 1,000 icebreaker ships are probably a drop in the bucket.

There is no traditional forecast for Alert at the Canadian Met Service website. But there is a 14-day ensemble of multiple model runs. It's not a forecast per se, but it's about all that's available. See www.weatheroffice.gc.ca/ensemble/naefs/EPSgrams_e.html By alphabetic accident, Alert is the first (i.e. default) station in the list. If you get a "No Image Available" message... * click the back-arrow on "Issued Day" * on the "hour" selector, pick 12 That'll give you 12Z yesterday, rather than 00Z today. Another useful one is the weather-at-a-glance 18Z forecast map at www.weatheroffice.gc.ca/jet_stream/index_e.html

Hmm Jaxa still heading downwards Looks like it will fall below 2005 minimum

Couple of arctic buoys above 80N showing under -10 now both reading -11.1. Alert -6. Eureka still fairly warm at 2. North most greenland coast at -7 Still a way to go, as there is plenty of heat left inside the arctic circle. This graph though should reflect these temperatures later today? ocean.dmi.dk/arctic/meant80n.uk.php

This graph though should reflect these temperatures later today? ocean.dmi.dk/arctic/meant80n.uk.php Salt water freezes at 271K, so we are on the cusp of re-freezing beginning in earnest in the northern latitudes. Does anyone know how much open water exists currently north of 80N?? Probably not much, but it's a start in the direction of slowing down the net daily melt. The first positive day will come soon.
