Longitude-Depth Section of Potential Temperature Anomaly Along the Equatorial Pacific Thermocline

This figure is a longitude-depth section of oceanic potential temperature monthly anomalies averaged from 5°S to 5°N along the equatorial Pacific thermocline.

This longitude-depth section extends from 121°E to 79°W, and from the ocean surface to a depth of 500 meters. The GODAS potential temperature monthly anomalies are calculated with respect to the 1991-2020 climatology, and are averaged from 5°S to 5°N. Contours begin at +/- 0.5°C and are drawn at an interval of 0.5°C. Yellow to red colors represent positive potential temperature anomalies, and shades of blue represent negative anomalies. The thick black line indicates the climatological position of the 20°C isotherm, often used as an indicator of the location of the thermocline.
