The Density of Water
The density of fresh water is 62.4 lbs/ft³, and the density of salt water is 64 lbs/ft³. Salt water is denser because of the dissolved salt.
Fortunately for us, water doesn't significantly compress when pressure is applied, so the density does not change with depth. This means that no matter how deep you dive, effects of density such as swimming resistance remain the same.
