Oceanographic observations off the Pacific Northwest following the 1982 El Niño event

The evolution of sea surface temperature anomalies off the Pacific Northwest during the 1982-83 El Niño seems to be in general agreement with their formation through poleward advection by a long wave. Oceanographic observations in May 1983 indicated significant positive thermal anomalies above 500 m; salinity anomalies showed a reversal in sign which implied both sinking of upper water and northward advection. Geostrophic flow along 47°N revealed no evidence of the California Undercurrent.
