Density of ocean water

About 1027 kg/m^3. The density of pure water is 1000 kg/m3. Ocean water is more dense because of the salt in it. Density of ocean water at the sea surface is about 1027 kg/m3. There are two main factors that make ocean water more or less dense than about 1027 kg/m3 : the temperature of the water and the salinity of the water
