countergradient eddy flux of heat, i. e., a flux of heat from 



the colder coastal waters to the warmer ocean. The observed 



heat and density fluxes are shown in figures 3, 4 and 5. It 



is remarkable how strong the observed heat transport is in 



the Onslow Bay and Cape Hatteras sections with, at the surface, 



a maximum of the order of +10°C cm sec"-*-, located near the 



maximum of the current. The transport decreases with distance 



from the axis of the current. In the Jacksonville surface data 



the mean temperature profile is flat and the corresponding heat 



flux small. Yet a small peak shows up similar to the maxima in 



the other sections, indicating again a transport against the gradient. 



With increasing depth below the surface the tempera- 

 ture gradient becomes steeper and the peak of the eddy heat flux 

 sharper. Even at Jacksonville, where the heat flux at the surface 

 is ill defined, there is a strong heat transport below the surface. 



In tables 1, 2 and 3 are also presented density 

 fluxes, computed from the available data for temperature and 

 salinity at the surface. In most cases the density transport is 

 towards the shore. However, the action is not quite so systematic 

 as for the transport of heat, except at Onslow Bay.
