Transects across the IPWP down to 500 m water depth for the contrasting periods (February and August) along three separated longitudes (top: 10°N, middle: equator, and bottom: 10°S). These images clearly show the shallow nature of the Warm Pool with temperatures dropping below 25 °C within less than 100 m water depth. Note the accumulation of very warm water to a greater depth offshore Papua New Guinea along the equator and at 10°S. Data accessed at the same web site listed in Fig. 1
