I was passed this map in a project that I am working on - a graphic designer had tried to assist specialist in delineating marine areas of interest on a global map - but the map is a total mess. Graphically it was ok, but... - yes just look at it. It didn't mark either where the end of the world was, so the marine areas are rectangular out to the borders of the image. And Antarctica. Note: this is not the image I was given, I removed all the delineated areas and labels (the white splotches).
I have reprojected this to Mollweide, which it resembles, but isn't. But does anyone have any tips on what projection it is? I tried the ones in ArcMap, but I couldn't (easily) find the right one (tried to match up the exported continents in Illy).
