I made that map with ice sheets / glaciers extent data from the University of Cologne, I got the lakes on Canada.ca and many other shapefiles (borders mostly) from divagis.org
I got the information from the encyclopedia britannica and I read a couple of research papers.
I used QGIS for the basemap layer and Adobe Illustrator for everything else
Feedback welcome !
If you like maps, I have many more on my website :)
cheers !

You’re right, but at this point everyone (the researches as well I think) say this. It’s the common way to designate the topic. It’s also simpler and more understandable that way

WTF ? I am not saying they’re acidic. I’m saying they are getting more acid. The pH has dropped by 0,2 during the period shown here. This means +30 in acidity. Not acid yet but it is definitely getting more acidic

How dare they, getting more acidic ? Tsssk the audacity

Thanks. I thought upwelling was bringing water along the coasts of Peru / Chile and Nambia ? Is it also happening in the middle of nowhere ?

The data resolution is very coarse so maybe it is very acidic locally (I haven’t read anything about ship lines and acidity though !) and the data doesn’t allow us to see it …

Also, I’ll add some patterns across oceans are currents, like you see in the northern Atlantic Ocean. The cold waters on the east coast of Canada are colder than those coming from warmer regions, so they get this sped up acidification effect…!
Also, it doesn’t show on the map so well but coastal waters tend to have a higher pH because of human activity and river discharge (bringing waste waters)

So the logic behind this map, as far as I know it, is that, from a purely chemical point of view, cold water is more acidic since the amount of CO2 that can dissolve into water is inversely proportional to the temperature.
So, this would mean cold water becoming warmer,because of climate change, should be less acidic. But then, in reality, more biological processes take place in warmer waters. These processes releases CO2 and acids. So water ends up getting more acidic
This degree of change is exacerbated by the fact polar waters are warming up much faster than the others on earth
That’s why it’s bright yellow, others who didn’t change so much are likely to not have warmed so much (or other reasons I don’t know)

Agreed. I will post the same map with a comprehensive overview of the topic, with more info and figures. But since this sub seems to appreciate simpler maps (because the map I made is a 3-4 mns read and no one has time) I’m posting this in the meantime

No, -0,2 means it decreased by 0,2 between the two dates

For this map I used the free data on NOAA (national Oceanic and Atmospheric Administration) and used QGIS / adobe illustrator process the data.
I will post a much more elaborate map tomorrow, adding a ton of extra information but wanted to share this simpler, straight forward version map of the topic.
In the meantime, you can find more cool maps, articles and even photographs on my website where I write about topics with a geographical point of view (hence the maps).
cheers :)
