PROFILE NO. 2— STATIONS 400-105 



The section runs from station -iW. located on the northwestern 

 side of the Grand Bank, northwesterly across the " gulley/* to Cape 

 Race. It was occupied April 17-18. one of the objects sought being 

 the charting of the underwater size and position of polar water. 

 if present, in the region around Cape Race, and also to determine to 

 what extent it spread southward over the Grand Banks. 



Sii/hilfi/. — The salt est water, 33.00 " ,,^,. lay on the bottom of the 

 ■" guUey," but on the Grand Banks side, away from the coastal slope. 

 The section cut two bodies of water fresher than 32.50 °/oo. one of 

 which hugged the shore of Cape Race and the other a mass which

flooded all depths, station 401, on the edge of the Grand Bank and on 

 the surface and had a width of 35 miles. 



Tem'peiatuve. — Water colder than 0^ flooded all stations, surface 

 to bottom, from Cape Race offshore to the edge of the Bank, where 

 it presented a nearly vertical temperature face which lay between 

 stations 402 and 401. The coldest water of the section, —1° to 

 — 1.2°, rested on the bottom of the " gulley " on the landward side, 

 with a maximum thickness of 45 meters (25 fathoms). 



The results of dilution from land drainage could be seen in the 

 low salinity of the surface layers which extended a long distance 

 off the coast. But the most important fact revealed from the view- 

 point of the patrol was the presence of pure Arctic water, which 

 tio.ided the " gu.lley "' at all depths but did not spread offshore
