Going off mean temperatures (because they're the best data I can find for the effort I'm prepared to put in), you're adding 1.3 billion cubic kilometers of water at 67C above the Mars surface mean, for a total of ~5 * 10^24 joules (5 yottajoules). That's about six years' worth of the energy received by Mars from the Sun. It'd certainly drag the surface temp up to above-zero, and the huge pile of water vapour added would likely thicken the atmosphere up to the point where you just need a gas mask rather than a pressure suit. Water vapour is also one of the best greenhouse gasses known, what with forming clouds and all.

Where did you get that volume number? It's off by a factor of about 150. (And yet, your depth figure is only off by a factor of about 4, which is closer, but which also means that whatever calculation you used lost a factor of almost 40.)Davidy wrote:The total amount of water on Earth is about 2,551,000 Mi3. The surface area of Mars is 55,910,000 Mi2. If all of Earth's water was dumped on Mars, it would cover the entire surface to a depth of about 22 Miles.

The rough calculation would be to simply divide. Some number of cubic miles of volume divided by some number of square miles of area gives some number of miles of (approximate) depth, which isn't the number you came up with despite having the correct values for the other two.Davidy wrote:gmalivuk wrote:That's... still wrong.
Okay, correct it please. Apparently I suck at math.

The thermal mass of the Earth's oceans is far, far greater than the thermal mass of the atmosphere of Mars plus the upper few kilometres of its crust. The new mean temperature would be very close to 4C, which is the average temperature of the oceans on Earth.
Also, having read a lil' more: the vapour pressure of water at 4C is about 800Pa. That's tiny by Earth standards, but on Mars, where average atmospheric pressure is 600Pa, it means the oceans would outgas until a large fraction of the atmospheric pressure is due to water vapour. The greenhouse effect would be immense.
