From: Southern elephant seal vagrants in Ecuador: a symptom of La Niña events?
Monthly negative anomalies of sea surface temperature (SST) in the Southeastern Pacific Ocean during October 2017 as an example to illustrate the presence of La Nina during the occurrence for southern elephant seals from October 2017 to January 2018 in Ecuador. The blue contour tones indicate where the SST are below the historical climatological value over the baseline reference period 1971–2000. The contour for SST anomalies in the map are shown in an interval range of 0.5 °C. The SST anomaly scale is in °C
