physics question i need help.

What would be the upthrust of the water (ie. upward force exerted by the water) be on a 70kg swimmer in a pool on a Mars base in the 21st century?

I believe we would need to know the gravitational field strength of Mars to answer this question, as the force in Newtons needs this value to caucluate the answer. By doing a quick google search, I got this value to be about 3.72 N/Kg, so the upthrust of the water on a 70Kg swimmmer would be (70*3.72) which is 260.4 Newtons.
