Abstract

El Nino-Southern Oscillation (ENSO) refers to the interacting global atmospheric and oceanographic conditions that sporadically alter large-scale atmospheric pressure systems, rainfall, ocean currents and sea levels largely in tropical and subtropical latitudes in the Pacific Ocean, and which involve a massive advection of warm, low salinity, nutrient-poor water to the south. During ENSO years the biological productivity of the euphotic zone declines suddenly, with negative effects on the survival and reproduction of populations at higher trophic levels. The nature of the severe 1982-83 event is outlined, and the environmental and ecological consequences are discussed, eg food limitation, dinoflagellate blooms, and changes in species abundance. Some extra-tropical effects are noted, and post-ENSO recovery is traced. Similarities between these events and bleaching of zooxanthellate invertebrates during 1987 are noted. -P.J.Jarvis
