I would like to reproduce this map which was originally printed in mare, a German magazine.
I have done some research and think it is a projection by Athelstan Spilhaus. I would like to be able to produce it using QGIS version 3. This is an interesting article about the projection: https://le-cartographe.net/blog/archives/342-athelstan-spilhaus And this is another interesting page from Jason Davies: https://www.jasondavies.com/maps/spilhaus/11/
I have tried with an antarctic polar stereographic projection (EPSG 3031) where I changed the standard parallel to various different lines of latitude but this does not show the north pole correctly, nor does it have the coastline around the edge. I have tried using a lambert azimuthal equal area projection with the latitude or origin at 0, but this doesn't get close to it either. It seems to be a mix between a Hammer and Petermann projection, according to the french article above.
How would I make this in QGIS? Is it possible? (I have a feeling that the answer is no, but I wanted to ask others).
