11 a. 111. Stootl S. until aijain clear of fog, at 11.25 a. m., then E. 

 until 12.30 p. m., when, being enveloped in fog which appeared likely 

 to continue, stopped and la}' to for the remainder of the day. Noon 

 position, lat. 41° 45', long. 50° 35'. Water temperature 62° F. 

 Later we drifted into cold Avater. Ice warnings w'ere sent to the 

 steamships Ampetco and Glenlvss. 



June 18: Light to gentle breezes, shifting from SSW. to NW. and N. 

 Foggy, partially clearing at intervals; passing rain showers about 

 daybreak. At 7.45 a. m., under way for Tail of Bank, to utilize 

 foggy weather for taking oceanographic observations. At 6.10 p. m. 

 anchored for the night, in lat. 43° 05', long. 50° 03'. Occupied an- 

 chorage site at station, designating it No. 335, at 9. p. m., and as No. 

 336 at midnight, taking temperatures to the bottom. Found decided 

 difference in temperatures" at same depth on the two observations, 

 indicating daily change in cuiTent. Ice information was furnished 

 the steamship Bellasco and ice warning was given the steamship 

 Kiruna. 



June 19: Light to gentle N. breezes. Overcast; foggy at intervals. 

 At 4 a. m., occupied anchorage site as station 337. Again found 

 temperatures at various depths to differ from those previously taken. 

 At 4.25 a. m. under way for small berg just sighted 3 miles distant. 

 At 4.50 a. m. rounded berg and photographed it, lat. 43° 08', long. 

 50° 03'. This was a sniall, solid berg, of pyramidal cross-section some 

 125 feet in length by 35 feet in height, completely water washed and 

 apparently afloat. Began rectangular search of area E. and S. of 

 Tail of the Bank. At 2 p. m. sighted a small berg, in lat. 42° 45', 

 long. 49° 55', and at 2.15 p. m. stood around same. This berg was 

 very similar in size and appearance to the one examined this morning. 

 Continued search until 9 p. m., when we lay to for the night off the 

 last berg sighted. At 10 p. m. fog again shut in. Occupied station 

 338 near berg, lat. 42° 45', long. 49° 58', this being in the axis of 

 the Labrador Current near the Tail of the Bank, where this current 

 is most pronounced. The temperatures recorded at the various 

 d(']>t]is were as follows: 



Surface, 6.3° C. 2.50 meters, 6.2° C. 



.50 meters, 4.3° C. 4.50 meters. 4.7° C. 



12.5 meters. 2.3° C. 750 meters, 3.4° C. 



It is to he observed tliat th(> water in whicli this berg lloated is of 

 positive temperature (above freezing). Unadulterated Labrador 

 CiuTcnt is of negative temperature at tliis time and place below the 

 sui-face. This is an indication, tlierefore, that tlie Labrador Current 

 at this j)oiijt was weak and that unusual mixing with warm Atlantic 

 water hud occin-red. It is further inlcrcsling to compare the above
