Twenty-one thousand ships a year thread the Gulf of Aden
Between Yemen and the Horn of Africa, the Gulf of Aden funnels Suez traffic toward the Arabian Sea—about 21,000 ships annually, many hauling Persian Gulf oil. Greeks folded it into their Erythraean Sea; medieval writers preferred “Gulf of Berbera.”
Yemen faces Djibouti, Somaliland, Puntland, and the Socotra group across water that meets the Red Sea at Bab-el-Mandeb and opens east to the Arabian Sea. The Aden Ridge tracks the floor. Greeks folded the basin into their Erythraean Sea; Muslim littorals later remade its politics, and Soviet naval interest rose from the late 1960s until Suez’s 1975 reopening revived commercial pulse after years of canal closure.
Roughly eleven percent of seaborne petroleum still rides this lane toward Suez or nearby refineries. Medieval writers such as Abu’l-Fida and the pilot Ibn Majid preferred “Gulf of Berbera,” recalling when Somali Berbera outranked Aden in regional fame. Shore villages land sardines, tuna, kingfish, and mackerel without big industrial fleets; turtles and lobsters belong to the same nearshore harvest. India alone moves tens of billions of dollars of trade through these waters yearly.
IHO limits run from Hisn Murad–Ras Siyyan on the Red Sea side to the Cape Guardafui meridian eastward, with Tadjoura as the western pocket. Temperatures swing between about 15 and 28 °C; salinity at ten metres can exceed 37‰ mid-gulf while oxygen holds near 4–5 mg/L. Ancient monsoon shortcuts linked Egypt, India, and China before caravan kingdoms frayed and piracy rose. Main ports still include Aden, Mukalla, Djibouti City, Berbera, Zeila, and Bosaso—proof a short deepwater gate can remain a world hinge rather than a local cove.
