A corollary?
That must've been a lot of work--thanks.
Given that the stratigraphy is based on a "standard" one cubic kilometer of seawater, would the stratigraphy we actually find somewhere scale to tell us the depth of the water?
Since that's terrestrial seawater, how much would the presumably different chemistry of a primordial martian sea complicate trying to derive the depth? And density? I know there's an upper bound of saturation, but are there other clues to calibrate the stratigraphy for the original density? I dunno, crystal formation, maybe?
So many question marks...
