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 :)
