Sounding profiles reveal a median ridge which coincides with the epicenter belt. Soundings by Mahahis (Farquharson, 1936) reveal that the section of Mid-Indian Ocean Ridge from Rodriguez Island to the Gulf of Aden (known as the Carlsberg Ridge) is longitudinally split by a prominent central valley. Recent cruises of Vema in previously unsounded areas have found a con-
