                         moorings at 0oN, 23oW collected during 2002, as well as 
                         accompanying satellite SST and winds are used to examine the 
                         Tropical Instability Waves (TIW) and their role in the mixed layer 
                         heat balance of the central equatorial Atlantic. The TIW appear as 
                         periodic 20-30 day fluctuations in currents which intensify 
                         beginning in June in phase with the strengthening of the 
                         southeasterly trade winds and the seasonal appearance of the 
                         equatorial cold tongue. Zonal velocity fluctuations are largest in 
                         July-August, while meridional velocity fluctuations are largest in 
                         August-September. The meridional component of velocity is also 
                         distinguished from the zonal component in that fluctuations of the 
                         meridional component extend coherently in the vertical to at least 
                         120 m while zonal fluctuations are coherent within the mixed layer 
                         only. Our estimate of horizontal eddy heat advection in the mixed 
                         layer averaged June-September is ~ 100 W m-2 with meridional 
                         advection dominating and peaking in late boreal summer. Averaged 
                         over the whole summer the contribution of the TIW events to the 
                         warming of the mixed layer is of 0.5oC, which corresponds to a 
                         modest value of the eddy heat advection of 15 W m-2. Since this 
                         value is very much less than the estimates of the summer mean eddy 
                         horizontal heat advection of 50 - 100 W m-2 this indicates that 
                         horizontal and vertical eddy heat advection balance in part. .",
