The temporal changes in the low-frequency thermal structure during a two-week period in August-September 1978 are discussed from moored data collected during the JASIN experiment. While some changes in the thermal structure appear to be related to local winds, the dominant low-frequency variability in the seasonal thermocline can be explained as horizontal advection of a spatially varying temperature field, and associated thermal wind, by geostrophic currents with little vertical motion or mixing required.
