This figure is a map of Mars. It is colour coded from white, through browns, green, blue and violet. The colours are overlain onto a topographic map of Mars. Violet represents the highest amounts of water in the upper metre of the martian surface. White represents the lowest amounts of water in the upper metre of the martian surface. The martian poles are coloured dark blue. The remainder of the map is coloured light blue to brown. There is no obvious correlation with topography.
