Which sea is the saltiest major sea?
Quick Answer
The Red Sea is the saltiest of the major seas, with surface salinity commonly around 40‰ and even higher in some areas.
The Full Story
The Red Sea is widely regarded as the saltiest major sea in the world. Its average salinity is around 40 parts per thousand, compared with an average ocean salinity of about 35 parts per thousand. In some parts, salinity rises even higher because the sea is very warm, evaporation is intense, and freshwater input is limited. The sea is also known for its coral reefs and clear waters. These conditions make it one of the most distinctive marine environments on Earth.
