211 meters (110 fathoms) at station 280 and increased to a depth of 

 450 meters (246 fathoms) at the outer station, 282. The mid stations 

 were flooded by water between 34.5 7no-35 %o, except on the surface, 

 where 33.5 %o-34.5 7oo water spread 180 miles out from the slope. 

 On the Bank. 30 miles inshore from the continental edge, water 

 fresher than 33 %o was found from surface to bottom. The slope 

 stations M'ere flooded by a body of water 33.5 %o> which extended 

 down to the 450-meter (246 fathom) level. 



Temperature. — ^We foimd the outer station to be in warm water 

 > 10°, the inshore boundary of this body being located between 

 stations 281 and 282 in the form of a precipitous wall, which extended 

 vertically downward to our maximum depth, 750 meters. A small 

 surface pool of warm water was found at station 280, it having become 

 disconnected from the main offshore body. Proceeding in toward 

 the Bank a strip of cool Avater was encountered 40 miles in width 

 and extending vertically downward for 750 meters (410 fathoms), 

 and inshore of this lay a belt waraier than 7° and of about equal 

 width. Inshore of this latter, in turn, the temperature fell rapidly 

 as we entered the cold water lying next to the slope. The only 

 subzero water was a small patch lying on the slope at the 75 meter 

 (41 fathom) depth. 



Summing up: Warm salt water (Gulf Stream) lay 180 to 200 miles 

 oft' the east continental edge of the Grand Bank, which is farther 

 offshore than it was found earlier in the season or durins: 1922. 

 In mid section we failed to find the shoulder of the Gulf Stream which 

 was charted there a month earlier. (See profile No. 1.) The warm 

 streak which was found separating cooler water on either side of it, 

 must by virtue of its high temperature and salinity, have been 

 related to the Gulf Stream at some time, which is suflScient for the 

 profile to illustrate the interlacing activity which has been observed 

 so often on the east side of the Grand Banks at this place. The fact 

 that we did not find such extremely contrasted water masses adjacent 

 to each other as observed earlier in the month (see profile JNo. 1) 

 would indicate that the circulation was less active April 26-28 than 

 April 11 (see discussion of profile No. 3). 



PROFILE NO. 6— STATIONS 283-286 AND 296. 



The section rtms from station "C" (see chart ''A") south out over 

 the slope mto deep water. The offshore end was not carried into 

 the Gulf Stream since the object sought was to chart the size and 

 position of the Labrador Current only. The stations were occupied 

 April 30-May 4. 



Salinity. — ^In over the Bank was found water fresher than 33'Voo 

 except on the bottom, where it was 33.01%o. Off the slope, and 

 as far seaward as the outer station, 283, the water was 33.08 ^L„-
