Previous research has shown that a 100-km² area in the central part of the southwestern lagoon of New Caledonia ('Banc Gail') consists of a field of mud-mounds built on oyster reefs. Erosion caused by land clearing and mining is assumed to have dramatically increased hypersedimentation in a recent past, which in turn is thought to have caused the extinction or near-extinction of Banc Gail's oyster populations. SCUBA-diving exploration of Banc Gail revealed a peculiar ecosystem now dominated by stalked or fleshy, mucus-producing corals.
