Salinity depends on a number of factors like rate of evaporation, rate of precipitation etc. Sunlight can penetrate only up to a certain depth (around 200 m or so) in the ocean. The zone up to which sunlight penetrates is called Photic zone. read more

Density varies with depth. In the lower latitudes (temperate and tropical regions), density is steady to about 200 m, increases to a depth of 1,000 m, and then remains steady below 1,000 m. read more
