Reply to comment by RhymesWith_DoorHinge in Mars was once covered by 300-meter deep oceans, study shows by magenta_placenta
Well Mars is only a third the size so it would roughly track as a ratio, no?

Good point. Just seems weird to have such shallow oceans, as an earthling.

I know, right? 300 meters? That could evaporate after a couple of hot July days

It's actually about 1/12 as deep as earths oceans are on average but it is close to a fifth the depth of the arctic.

Not a third the size, it has 10% the mass, Mars is ten times smaller than Earth, with about a third of the surface area.
