What Is the Density of the Red Sea? Temperature and Salinity Effects

Red Sea density ranges from 1.024 to 1.028 g/cm³.

Variation is driven by:

• Temperature: Surface waters warmer → less dense.
• Salinity: High evaporation → high salinity (~40 PSU) → denser water.

Density increases with depth as water becomes colder and saltier. This stratification influences circulation, nutrient mixing, and marine life distribution.
