By now the bergs previously noted north of latitude 51° N. had 

 drifted southward and were to be found concentrated from Cape Bona- 

 vista, north northwest to approximately 120 miles off the coast of New- 

 foundland opposite Groais Island. As usual the bergs were entrapped 

 within the sea ice limits. Only one berg, located approximately 60 

 miles northwest of Virgin Rocks, was to be found on the Banks. 

 Figure 3 shows the distribution of bergs south of Brevoort Island, 

 Baffinland. 



MARCH 



Continuation of warm winds improved ice conditions. The south- 

 ward drift of field ice was compensated by the deterioration of its 

 leading edges. By mid-month the field ice had again advanced to 

 latitude 48° N. Onshore winds througli the 21st continued to contain 

 the field ice, considered open pack, and the bergs along the coast. 

 Several bergs drifting in the Labrador Current reached as far south 

 as latitude 46° 54' N. on tlie eastern slope of the Banks. The drift of 

 the field ice within the Labrador Current was negligible and the 

 southern extension was, by mid-month, just south of latitude 48° N. 

 Most bergs were contained witliin the limits of the field ice. 



During the second half of March, south of Cape Freels, colder than 

 normal air temperatures accompanied tlie westerlies. North of lati- 

 tude 50° N. onshore winds prevailed. As a result, almost half of the 

 bergs, grounded for about 1 month near Cape Freels, drifted easterly 

 and moved rapidly southeasterly under the influence of strong west 

 northwest winds and the Labrador Current. Eighteen bergs drifted 

 south across latitude 48° N. Ten bergs remained on the northern 

 slopes of tlie Banks with seven following the eastern contours of the 

 Banks. The southernmost berg was located well eastward, being at 

 latitude 45°20' N., longitude 45°50' W. By the 30th, under normal 

 weather conditions, the field ice and bergs had drifted soutli to ap- 

 proximately latitude 47°25' N., west of longitude 50° W. This is 

 south of the eastern component of the Labrador Current and boded 

 well. Figures 4, 5, and 6 show the distribution of bergs south of 

 Cape Chidley. 



APRIL 



Aerial ice reconnaissance flights on the 1st and 2d showed an influx 

 of ice on the northern Grand Banks as far south as latitude 47°20' N. 

 The field ice had drifted eastward to about longitude 49° W. East of 

 longitude 50°30' W. it was open pack. One small berg located at lati- 

 tude 46°07' N., longitude 47°16' W. was in the southward-moving core 

 of the Labrador Current. Maximum sea ice penetration occurred on 

 the 1st, but St. Johns remained open. In the next several days liigh 

 southwesterly and southeasterly winds caused the sea ice to recede to 

 north of latitude 48° N. By the 8th tlie field ice was deteriorating i-ap-
