the limits of its 200-mile station. Such sighthigs are rare and are 

 outside of or close to the limits of iceberg occurrence as shown on 

 hydrographic cliarts and pul)lications. The first instance was 15-18 

 March when the berg was sighted in position 56°23' X., 50°29' W., and 

 tracked to meltuig at o4°5r X., o0°40' W. The drift averaged 22 

 miles per day in a south-southwest direction. The second case was 

 from 22-25 March with the berg first sighted in 56°27' X., 50°38' W., 

 and abandoned hi 54°55' X'., 51°15' W., when it reached the southern 

 limits of the ocean station after a 22 mile-per-day southerly average 

 drift. 



Other extreme ice sightings were by M/V J6kulj'ell on 20 March 

 which reported four bergs at 57°20' X'., 39°10' W., SS Mormacsaga 

 which siglited a small berg in 56°39' X., 39°57' W., on 21 March and 

 an unidentified aircraft whicli reported a large berg in 56°o0' X., 48° 

 00' W. Certainly these latter bergs and probably the OSV Bravo 

 bergs were of East Greenland origin. 



Ice reports received during March for tlie area south of latitude 49°

APRIL 



The suspected southerly movement of icebergs into the Grand 

 Banks area at the eiul of March materialized during the first week of 

 April when the season's crop of bergs was observed to be approaching 

 the northern slope of the Banks unck'r the influence of the Labrador 

 Current. The axis of the berg movement can be deduced from figure 

 10 whicli shows conditions as they existed at the end of the second 

 week. Here the forefront of the bergs is shown breaking out of the 

 pack ice which has achieved very nearly its maximum southward 

 extrusion from the year. The first berg of the season to drift across 

 the 48th parallel did so at this time. 



It is interesting to note that throughout the month this berg 

 movement coincided in its entirety very nearly with the eastern branch 

 of the Labrador Current. By the month's end 33 bergs had crossed 

 latitude 4S° X^., of which 27 did so during the last week. Xone had 

 been observed along the east coast of X^ewfoundland south of Cape 

 Freels. 



After occupying the limits on 15 April shown by figure 10, the 

 pack ice changed little throughout the remainder of the month. 

 The rate of deterioration along the southern boundary very nearly 

 equalled the rate of southward movement. At the month's end a 

 dominant northerly wind in the Belle Isle area resulted in a heavy 

 concentration of ice being carried to the northern slope of the Grand 

 Banks, and an encroachment of ice along the east coast of X'^ewfound- 

 land as far as Baccalieu Island. Warming sea temperatures prevented 

 any major spreading to the south, however. 



Ice in the Gulf of St. Lawrence deteriorated steadily and shipping
