Speakers Bank

From Wikipedia, the free encyclopedia

Speakers Bank is a large coral atoll structure in the Northwestern part of the Chagos Archipelago. It is the northernmost feature of the archipelago, located at 4°55'S, 072°20E, 22 km Northwest of Blenheim Reef and is 44 km Northeast-Southwest, and 24 km wide. The total area exceeds 800 km 2, mostly water. Most of the rim of the reef is between 5.5 and 14.5 meters below water. In the South, near the SW edge, there are some coral heads at 05°04'S, 072°16'E, which dry 0.5 meters during low tide and over which the sea breaks heavily during the Southeast Trade Winds. In the Northeast, at 04°47'S, 072°26'E, there are a number of drying cays, the biggest of which, Big Speaker Reef, just reaches the high water mark. The land area is negligible.

Speakers Bank was surveyed in 1856 by British captain J. Speaker on HMS Wallerup. It is the site of many wrecks, also from prior times.
