The Red Sea reaches its maximum depth of 2,730 meters in the central Suakin Trough. Its average depth is 490 meters, and approximately 40 percent of its total area is less than 100 meters deep.
The Red Sea is among the saltiest bodies of water in the world because evaporation is extremely high and rainfall averages only 60 mm per year. No significant rivers or streams drain into it, and its connection to the open ocean through the Gulf of Aden is narrow. Salinity ranges from around 36 parts per thousand in the south to 41 parts per thousand near the Gulf of Suez.
Ancient Egyptians conducted expeditions down the Red Sea around 2500 BCE and again around 1500 BCE, during the reign of Hatshepsut, seeking trade with Punt. Darius the Great of the Achaemenid Empire built a canal linking the Nile to the Red Sea at Suez in the sixth century BCE. The Roman Empire favored the Red Sea as its main corridor for trade with India starting under Augustus.
More than 1,200 fish species have been recorded in the Red Sea, of which 10 percent are endemic and found nowhere else on Earth. The sea also hosts 44 recorded shark species and over 175 species of nudibranch, many of which are also endemic.
Since November 2023, Houthi forces have launched more than 100 attacks on vessels in the Red Sea. The sinking of the MV Rubymar in February 2024 released approximately 200 tons of heavy fuel oil and 80 tons of marine diesel oil, creating an 18-mile oil slick. Ships rerouting around Africa have increased per-voyage CO2 emissions by approximately 40 percent, with some weekly shipping services seeing total fleet emissions rise by an estimated 67 percent.
Approximately 12 percent of global trade passes through the Red Sea, including 30 percent of global container traffic. The route shortens the journey between Asia and Europe by roughly half compared with sailing around Africa.
