Abstract
The causes and effects of the oceanographic and atmospheric phenomena known as El Nino and the Southern Oscillation (ENSO) have been studied intensively in recent years (Cane 1983, Rasmusson and Wallace 1983, Barber and Chave 1983, Cane and Zebiak 1985). ENSOs occur at semiregular intervals of 3-4 years, and the stronger events have important biological consequences, including reduced breeding success and survival of seabirds in the central and eastern tropical Pacific Boersma 1978, Barber and Chavez 983, Schreiber and Schreiber 1984, Duffy 1986). The ENSO event of 1982-1983 was perhaps the strongest of this century Cane 1983), and there is evidence that seabird populations as far north as the Oregon coast (42-46'N) were adversely affected (Hodder and Graybill 1985, Bayer 1986). Here I examine evidence for similar effects on seabirds along the Alaskan coast.
