transport off Onslow Bay and Jacksonville were computed at 

 depths of 30 m, 60 m and lOO m. It seemed reasonable to use 

 in these calculations the surface velocity measured by the GEK 

 as representative of the current down to a depth of 100 m. At 

 any rate velocities were available for the surface only. For the 

 cruise south of Cape Hatteras surface data only were used in all 

 computations. 



Discussion of the observed heat and density transport 



Upon examination of a temperature cross section 

 of the Gulf Stream one notices a strong horizontal temperature 

 contrast between the slope water and the Sargasso Sea in the 

 vicinity of the current maximum (see e, g, fig, 2), One is imm.ediately 

 tempted to ask the following questions: Is there a transport of 

 heat across the current produced by the meanders and, if 

 present, is this flux down the gradient and what is its magnitude? 



The calculated values of the eddy fluxes of heat 

 and density are presented in tables 1, 2 and 3, Assuming that 

 the present data are representative for the layers of the Gulf 

 Stream near the surface, the observations suggest an unexpected 

 answer to our questions. In all three sections there is apparent a
