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.
