STATION 385 



It will bf recalled that comparatively little northern water, con- 

 fined to the upper 100 meters (55 fathoms), was found at the Tail, 

 station 37;). on March 23.-' "When we took station 385, April -1. only 

 5 miles southeast of station 379, in (><•(» fathoms of water, on the slope, 

 berg Xo. 2 was close by, drifting southwestward at the rate of 0.35 

 knot per hour, which is most direct evidence of an arctic discharge. 



Cold water with a temperature of 0.2" to 1.1". flooded the surface 

 layers to a depth of 125 meters (OS fathoms). Such temperatures 

 while according with a northern source are higher than the normal 

 average of those found in the heart of the Labrador Current during 

 previous ice seasons, or even at this time farther north along the east 

 side of the Bank.-- This indicates an arctic influence and mixture 

 at station 385 as distinguished from the main unadulterated body 

 which lay northward on the continental edge. Below 125 meters ((58 

 fathoms) all traces of northern temperatures disappeared, being re- 

 placed in the deeper layers by water warmer than 2.3°, which was 

 sufficient to identify this body as slope water. 



The surface layers to a depth of 125 meters (68 fathoms) were 

 fresher than 33.25 %o, but from 250 meters (137 fathoms) to the 

 limit of investig-'ation the water was considerably saltier, 34.42- 

 34.24 °/oo- This corresponded to the distribution of temperature. 

 Cold fresh layers spread over warmer saltier water. But the most 

 significant event in connection with the shallow surface layers of 

 northern complexion off the Tail was the presence of an iceberg which 

 was drifting southward in this water. Although berg No. 2 had 

 emerged frotm pure Arctic water and floated in the zone of mixed 

 water which lay close inshore to the slope, it continued to drift south- 

 ward with no apprecialde reductiou of rate.
