You might think 300 meters is a lot, but that’s just peanuts to Mars

Just Mars's mantel is 1,560,000 meters deep. The mantel material is also more dense than water. Problem is is size is relative. 300m of water is a crazy amount to us humans, but to a planet's mass, it's not that much.

Equivalent to those little cups of water we hand out to people running a 5k.

For comparison the average depth of Earth's oceans is more than 3,000 meters with the deepest points going in excess of 10,000m and Earth has much bigger surface area. And Europa's oceans are theorized to be around 100Km deep.
