Mars Was Once One Third Ocean




I had a post about an applet that let you set the height of the Mars and Venus oceans to see how it would look.

World Building Query: All other things being the same, the photic zones for Mars and Venus (given terraforming) are going to be different than Earth's. Mars' will only penetrate to 50m (guessing here since there is 1/4 the light) whereas Venus would have 400m (twice the light).

Personal preference is for Venus to have a +700m depth in the applet making the deepest parts of its world ocean no more than around 1800m deep. With Mars, I prefer a +350 m depth which makes parts of the Hellas Planitia/Sea deeper than 7850m. Still not even as close as the Mariana Trench.
