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 !

Interesting gifs - thanks - could the changes be due to more / less snow drifting over or into crevasses - or being blown away?

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

Thanks Iain - somehow it would be more convincing if the map was a bit more credible and the spinning disk of tea was a bit better placed / scaled - it looks way out in space to me!

Many thanks Baking for the gifs!    Any chance it could pause / stop at the latest with a click to restart - its hard to see when its rolling round and round (and I dont know how to put it on slow-motion).

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.

I think its amazing to look at the two lowest on this day - #290 in (2012 / 2019)
NSIDC - 5 day EXTENT. 

The 1981 - 2010 median line is certainly way outside the current ice area!

Looks like there is a first glimmer of ice around the coast lines starting though....

And for commercial traffic its certainly going to increase.....

Whilst the Russians seem to have a handle on their "official" opening date.

And in 2023 ...

Will look for some statistics as well...

Arctic sea ice / Re: Northern Sea Route - Days Open
« on: October 14, 2019, 10:20:38 AM »

I know - just emphasises the difficulty for the definition of "open".  Presumably it could be:

 Navigable with icebreaker escort
 Navigable by ice-class vessel
 Navigable by ordinary commercial vessel
 Navigable by private vessels e.g. sailing boats

I think most of the tracking programmes need subscriptions to view historical data, but can identify individual ships (assuming they havent gone dar b turning off AIS!

Arctic sea ice / Re: Northern Sea Route - Days Open
« on: October 13, 2019, 08:12:35 PM »

I would have thought the open / closed / in transit status of shipping (e.g. hydrocarbon exports ) would give a good clue...

as an example

Extent gain in this freezing season to date is 839k, 544 k (9.3%) less than the average gain to date of 1,383 k.
9.3% should read 39.3% perhaps ?
Many thanks for the regular updates too!

The forum / Re: ASIF Statistics
« on: September 24, 2019, 05:02:33 PM »

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!  ;)

The forum / Re: ASIF Statistics
« on: September 24, 2019, 01:38:01 PM »

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.

« on: September 23, 2019, 03:52:15 PM »

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.

Arctic sea ice / Re: 2019 sea ice area and extent data
« on: September 18, 2019, 07:09:12 PM »
Isn't that exactly why there is the NSIDC 5 day trailing average - to avoid the daily swings ??  I imagine there will have been a lot of thought into how many days makes the best curve i.e 3/4/5/6 days etc - to give sensible, but without either losing the irregularities or smoothing the data too much.

Is there a structural reason for the massive discrepancy of -10k from Juan G and - 73k NSIDC daily from Alphabet Hotel.  i.e one is yesterday vs today? 

In which case can we expect one to "catch up" tomorrow?

KTB - I may have missed earlier messages - is your BOE  1m km2 or 0 km2 ? 

Why isn't 27 / 28th June showing as True where daily loss is albeit briefly > loss rate required for BOE ?

... or how about dashed line(s) e.g 10 yr / 5y could be dashed ?   I wouldn't do last 5 dashed as they may be close.   Or earlier ones (pre 2000 / 2010 even) as faded colours / very fine lines.

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.

Thanks Wipneus for these - any chance of a version where the 2018 (and later 2019) can be seen maybe dashed / different colour / thickness as there are three with almost identical reds on my screen?    Many thanks.

An easier read on the subject:

World's oceans absorbing 60% more heat than we thought, study says

The world's oceans are warming at an accelerated rate and are much warmer than scientists thought -- and things could get a lot worse if nothing is done to stop climate change, according to a new study.

The data, published in Thursday's edition of the journal Science, shows that the oceans have experienced consistent changes since the late 1950s and have gotten a lot warmer since the 1960s. The oceans are heating up much faster than scientists calculated in the UN assessment of climate change released in 2014. ..............

Not sure where this should go - but worth noting - looks like the Magnetic North Pole is sliding away from Canada / USA towards Russia.

I don't think this a DCMarvels superhero style achievement by some dastardly scientist / politician.....

"OSLO (Reuters) - Rapid shifts in the Earth’s north magnetic pole are forcing researchers to make an unprecedented early update to a model that helps navigation by ships, planes and submarines in the Arctic, scientists said.   
Compass needles point towards the north magnetic pole, a point which has crept unpredictably from the coast of northern Canada a century ago to the middle of the Arctic Ocean, moving towards Russia....... "

I have done this as a separate thread to (hopefully) avoid clogging the others !
