Abstract
A high correlation exists between the 20°C isotherm depth at the north equatorial countercurrent trough of dynamic topography and the monthly mean sea level at Truk Island. The meridional topography of the main thermocline depth can be used to monitor the strength of the equatorial currents, in the same manner as dynamic heights and sea levels at oceanic islands are used.
