Cocos Island (Pacific of Costa Rica) coral reefs after the 1982-83 El Niño disturbance

Cocos Island coral reefs were adversely affected by tbe 1982-83 El Niño warming event. Surveys made in 1987 indicated dramatic coral mortality at aH depths (l -24m). Live coral cover on tbree studied coral reefs was 2.6, 2.9 and 3.5%. Population den sities of the corallivores Acanthaster planci and...
