The Gulf of Aden is a deepwater gulf that separates Yemen from the Arabian Sea to the east, Djibouti from the west, and the Guardafui Channel, Socotra, and Somalia from Yemen to the south. It links to the Red Sea in the northwest via the Bab-el-Mandeb strait, and to the Arabian Sea in the east via the Arabian Sea. It narrows into the Gulf of Tadjoura in Djibouti to the west. The waterway is part of the vital Suez Canal maritime route that connects the Mediterranean Sea to the Arabian Sea in the Indian Ocean, with 21,000 ships passing through each year. This route is frequently utilized for delivering Persian Gulf oil, making the gulf an important waterway in the global economy.
