profile) that 3° to 4° water was continuous right across the western end of the bank 
at the 10 to 30 meter level. 
Our experience has been that the water is so actively mixed by tidal currents 
on the shoaler parts of Georges Bank that a complete equalization of temperature may 
be expected there locally at any season. Had the western profile (fig. 15) cut such 
a location, the readings would have been about 4° to 4.5° from surface to bottom; 
but with a difference of about 0.1 per mille of salinity between the surface and the 
bottom in 50 meters at station 20047 (p. 998), evidently such was not the case.
