gulfed in this locality sometime between April 17 and May 2. 

 The only direction from which cooler and Salter water may flood is 

 the north and northeast, and this corresponds witli a movement 

 noticed in the surface layers during this time.^^ 



The course followed by a small berg- in this locality substantiates 

 a southwesterly movement of the surface layers in this region, but. 

 if the path of this berg be folloAved further, it will be noted that it. 

 did not continue across the western slope of the Bank, but soon after 

 May '2 it swung to the eastward, where it eventually melted. Such 

 a drift to the eastward was compromised in a great part by the 

 ortshore southeasterly movement of fresh coastal water ■^'' whicli 

 spreads superficially over the south central area of the Grand Ban!-: 

 via its western side. 



PROFILE NO. 5— STATIONS 432-442 



This section runs from Cape Pine west-southwesterly, gradually 

 parts from the Newfoundland coast, and crosses the depression in 

 tlie shelf, bisecting St. Pierre Bank. The offshore end of the line 

 extended 10 miles off the edge into the deep water of the Lauren 

 tian Channel. The object sought was to trace the inshore portion of 

 the Arctic current which flows past Cape Race and which, it ha> 

 often been claimed, continues doAvn the United States coast inshore 

 of the Gulf Stream. The observations, which consists of 10 sta- 

 tions, were made May 3-4. 



Salinity. — Comparatively salty water, with a salinity of 33.00 "/,„ . 

 lay 75 meters (41 fathoms) thick, in the depression between St. 

 Maiys Bank and St. Pierre Bank. The freshest water. 32.18-3-2.6u 

 Voo flooded all depths at the two inshore stations (432 and 433) and 

 extended 27 miles out from the coast on the surface. A body of 

 water, also fresher than 32.60 ^/„„. was found extending from sur- 

 face to bottom on St. Pierre Bank, except at 439. where it was salter 

 than 32.60 V„„ below the sui-face. Off the edge of the shelf, at the 

 outer station (442). the water was niso salter than 33.60 "/,„„ except 

 on the surface. 



TempcmtKre. — The coldest water, 0°, a layer 25 to 100 meters ( !:'> 

 to .'>;■■) fath(mis) in thickness, rested on the Newfoundland shelf. It 

 extended from S miles off Cape Kace to the middle of St. Piei re Bank, 

 where it ceased between stations 439 and 440. AVaier colder than 1 =
