Webster defines climate as the average course or condition of the weather at a place usually over a period of years as
exhibited by temperature, wind velocity, and precipitation. But the more and more we look for the average ocean we realize
that the average is difficult to estimate because it changes on many time scales. El Ni\~{n}o climate and ecosystem effects
off Peru are a shining example of this variability, and for years we thought these effects were restricted to the coastal
oceans of the eastern Pacific. Careful studies in the central gyres of the Pacific uncovered El Ni\~{n}o effects there as
well. More recently our focus has shifted to decadal-scale changes that show remarkable basin-wide coherence and strong
impacts on the oceans ecosystems. This presentation will provide examples of the biological response to inter-annual to
multi-decadal climate variability.
