1387 and 1386 is 11 miles a day, and between the stations 1377 and 

 1378, 4 miles a day. 



The track of two icebergs will be seen on the current map. The 

 bergs were first sighted on April 29, and the ice-patrol cutter followed 

 them until May 2. The average velocity of the drift of these two- 

 bergs was practically the same, namely, about 30 miles a day. After 

 the observations on the stations 1375 and 1374 one clearly sees that 

 there was a strong southerly set between the stations. The "Jacob- 

 sen-Jensen method" does not, however, give any accurate result for 

 the station 1374; the difference in depth for the station and station 

 1375 is too great. It is, therefore, not possible to calculate the accur- 

 ate current velocity between the two stations. By careful exterpola- 

 tions and smoothing out of the station curves it was, however, found 

 that a velocity or about 45 miles a day might be a reasonable rate of" 

 the current. According to the drift of the two bergs, this velocity 

 seems not to be improbable. 



One might have expected that the bergs had continued drifting 

 southward and not turned to the east. The reason for this movement 

 must be that they were rather small. Both bergs moved slowly up- 

 and down with the swell, and in the afternoon on May 1 one of them 

 turned slowly over. The drift of the bergs, accordingly, due to the 

 shallow draft, was likely to be influenced by the wind. May 1 was 

 a nice and calm day, but in the evening it started blowing from NW. ; 

 and this wind must have pushed the bergs to the east and out of 

 the current. 



A closer study of the distribution of warm and cold water in 100' 

 and 200 meters depth can easily be made on the Figures 23 and 27. 



MAY 21 TO MAY 29, 1932 



This current map is based on 39 oceanographic stations (station 

 No. 1390 to station No. 1430). The positions of stations 1422 and 

 1423 are not accurate. The following current velocities have been 

 computed : 



Between the stations 1391 and 1392 about 16 miles a da3\ 

 Between the stations 1399 and 1400 about 20 miles a day. 

 Between the stations 1404 and 1405 about 33 miles a day. 

 Between the stations 1416 and 1417 about 18 miles a day. 

 Between the stations 1417 and 1426 about less than 1 mile a day. 

 Between the stations 1421 and 1422 about 19 miles a day. 

 Between the stations 1419 and 1420 about 18 miles a day. 

 Between the stations 1407 and 1408 about 8 miles a day. 



On the current map. Figure 20, is also drawn the track of five 

 different icebergs. Two of these were first seen on May 10 at about 

 44° 30' N. I have made the eastern most of the bergs black, in 

 order to make the map easier to read. Both bergs drifted southward
