3 Negligible. 
With the entire column of water on the whole lightest (specific volume greatest) 
along shore and heaviest (specific volume smallest) off the mouth of the bay at the 
time, the direction of the gradient drift was clearly anticlockwise around the bay 
and outward past the tip of Cape Cod (fig. 199), but also with a southerly component 
crossing the mouth of the bay more directly from north to south. A pool of low 
density in Cape Cod Bay must have tended to produce a subsidiary clockwise eddy 
occupying most of the area between the Plymouth shore and Cape Cod. 
The calculated directions and velocities also show a second but smaller eddy of 
the same sort centering over the southwestern edge of Stellwagen Bank, though this 
would not appear from the distribution of density at the surface.
