 Avarnier than at any other place. It is difficult in profile to differ- 

 entiate by either salinity or temperature sections, the bounds of 

 northern and local water. Considerina- the position of the water 

 most likely to be local in character, however, as that over the mid 

 section of St. Pierre Bank, and that in the surface layers of the mid 

 stations, it is estimated such local water was cooled to a mininuuu of

temperature attained by winter cooling in the south-central Bank re- 

 gion. The water transported around Cape Race along the south coast 

 of Xewfoundland, from a northern source, lay on the shelf as a frigid 

 bottom cover sheet, but did not extend westward of station 440 in the 

 middle of St. Pierre Bank. The horizontal and parallel position of 

 the isotherms indicates a water mass comparatively free from dis- 

 turbed mixing on the shelf along the south coast of Newfoundland.
