Interesting comparison. We should probably include the full reference for the paper you are referring to here. I think it is:Harrison and Jackson (2014) Exposed evaporite diapirs and minibasins above a canopy in central Sverdrup Basin, Axel Heiberg Island, Arctic Canada. Basin Research 26, 567–596, doi: 10.1111/bre.12037
Also, the Harrison and Jackson map includes rock units under the water. We would never see these in satellite images, so you should remove these areas or mark them with a different colour.
