Arctic sea ice / Re: 2020 Sea ice area and extent data

Keep up the great work, geron and Juan...sounds like a 70s pop group
But I thank you for the thankless (not anymore) daily task!

Plus one - many thanks for all the regular data - hard work and much appreciated !

Certainly quite warm here in South-West France, no sign of freezing conditions yet (projection 4 - 12 deg c for next 10 nights/days), but has been crazy wet. 8)
Seasons greetings and thanks for the informative, regular posts. ;D

So that explains it!

Maybe something like this ….


As we are putting pet irritations here - how about the dates...

Is today the 27/10/19 - or 10/27/19 ?

I find Day / Month / Year easiest (and perfectly logical as they are ascending order of size) but the US standard seems to be month / day / year for some reason  -  and of course that is the one overlaid on many of the downloaded images.... 

Obviously when speaking you could equally say "27th of October" or "October the 27th"

aaaaagh - off now for a free extra traditional hour in bed (or 0.041667 of a day....)

Thanks Stephan - timely reminder....

I think there is something to be said for viewing the melt and later freezing as being behind / ahead x days. 

Most of the statistics are km2 above / below average / record - whereas maybe a good way of looking at it is that we are 10 /31 days behind in the freezing  compared to average - and will probably have 10 /31 days "less" freezing as a result.

Don't mind - I was interested in the philosophy - personally I like all of the "data" posts - but I only do a "Like" for a particularly insightful comment /post (which could be embedded in the data post - or a separate one on that thread or elsewhere) - I guess its up to everyone to decide.   

I can't see / dont know if a particular post has been liked - that would soon bump the numbers up & probably skew things, and there is a certain irony in "Liking" a report of say a fall of 100k in sea ice area.  Its usually easer to make the decision in the Arctic Sea Ice Images section!

Facebook goes a bit mad with "likes" so very happy not to go down that route!  ;)

Aren't the "likes" for individuals doing exceptional posts - probably posts above and beyond the "normal" ?  We cant see the likes related to each post I dont think
Think they were only introduced in 2018 too ....   

If we all did a "like" for each time a set of graphs or statistics is posted for example they would soon add up but not sure they would mean as much imho.

I think the daily updates of several slightly different data sets are great - and my thanks as well like Phil42 to everyone that does them as it takes real dedication!  :) 

I think the smoother 5 day trailing NSIDC is handy as well then we have the monthly data & occasional trailing year data.  That's probably enough different timescales (certainly for me to get my head around).  I am sometimes worried that comparing todays data to historical "on this day" may be risky as there can be sudden jumps >100 occasionally which may skew the historical daily figs.

Sorry Tom - I dont think we should get into the perfection of predictions argument in this  data thread  though!  :(

Aluminium - though that is the measure of quantity of responses I am not sure that is the best indicator for the quality of the thread (or even level of engagement) - it may encourage too many off-topic posts or multiple (almost) identical posts - extra weather maps / speculation etc.

Gero:  ....and something very odd is going on.

Wondering what surprise(s) may be in store then.....

Dunno why it went tiny !!!

PETM - What do left and right sides represent?  Thanks

Antarctica / Re: Sea Ice Extent around Antarctica
« on: August 18, 2019, 09:03:29 AM »
- Extent LOSS on this day 37 k, a variation of 2 k from the average gain of 35 k on this day.

Is that GAIN, 72k or loss ?


Antarctica / Antarctic Expeditions
« on: February 11, 2019, 04:27:33 AM »
There doesn't seem to be separate topic for Antarctic expeditions - of which there have been quite a few recently.

Currently at least two major new ones -
A) Looking for Shackleton's ship in the Weddell sea &
B) the joint Thwaites investigation - multiyear project

We have also just had two one-man crossings of the Antarctic and the recycled Antarctic solar truck trip to the pole.

Links to current ones:
updates seem just in News section

Aluminium - what do the different lines lines etc represent ?  I cant see a key to the graphs.  Thanks

Amazing footage in this Reuters video of Helheim glacier: calving

Wow !

Or if you want to know how solar radiation with latitude changes with date see:

Others have posted similar ones - but as arctic circle is at ca 66deg north - this graph illustrates when incoming energy to the arctic drops to nothing.

Yes = please show as a larger image - i cant see anything even when downloaded / zoomed - thanks !

Antarctica / Halley base shut down and new crack in Brunt shelf
« on: January 16, 2017, 06:30:16 PM »

The British Antarctic Survey is to pull all staff out of its space-age Halley base in March for safety reasons.
The highly unusual move is necessary because the Brunt Ice Shelf on which the research station sits has developed a big new crack.

Lets hope it can get fixed !
