The circulation resulting from such a dynamic topography is 

 shown on Figure 46. A current ran southward along the edge of the 

 slope to the forty-fourth parallel, where most of it was turned back 

 to the north, joining a countercurrent which swept in from offshore 

 at this point. The inner edge of the countercurrent between the 

 forty-fourth and forty-fifth parallels was only 30 miles seaward of the 



Fig. 45. — Set IV. Dynamic topographic map drawn from observations made at stations 739-769, 

 May 29-June 3, 1927. This map is read the same as an ordinary isobaric weather map 



100-fathom curve, but it later became deflected offshore just north 

 of the forty-fifth parallel, and without doubt eventually passed 

 south of Flemish Cap. 



The form of the isotherms and the isohalines are unusually in- 

 structive when compared with the current arrows on Figure 46. 

 The position of cold and warm water, also of the salt and the fresh 

 masses, indicate the southward flow next to the slope to be that
