The Chagos-Laccadive Ridge (CLR), also known as Chagos-Laccadive Plateau, is a prominent volcanic ridge and oceanic plateau extending between the Northern and the Central Indian Ocean. The CLR extends northward for approximately 2350 km from 9° S at the southern end of the Chagos Archipelago to 14° north around the Adas Bank. The islands of Chagos, the Maldives and the Lakshadweep are the above-water parts of the Chagos-Laccadive Ridge.
