sighting on the 16th of a berg 47^45' X., 45°15' W. An ice observation 

 flight on the 21st sighted two bergs in 46°24' N., 45°o8' W., and 

 46°30' N., 45°48' W. Both the reports on the 6th and the sightings 

 on the 21st foreshadowed the large number of bergs which later in 

 the season inundated the Flemish Cap area. One of the bergs sighted 

 21 March drifted into track C on 22 March and was sighted in 46°12' 

 N., 45° 19' W. Since other bergs were sighted in this area also 

 threatening shipping on track C a recommendation was made to shift 

 the effective track from C to B which shift was accomplished 24 

 March. After the 22d, the number of reports and sightings of bergs 

 south of 47° N., increased and by the 31st several bergs were sighted 

 in the vicinity of 45°20' N., 48°35' W., and a growler at 45°02' N., 

 48°42' W. More bergs were contuiually entering the area and at 

 the end of the month approximately 40 bergs were strung out along 

 the 100-fathom curve between 47°00' N., 47°30' W., and 49°00' N., 



5roo' W. 



For the first 8 days in March the limits of drift ice remained approxi- 

 mately the same as those at the end of February. Then a gradual 

 movement south was observed and drift ice limits were defined on the 

 12th by a fine from 46°20' N., 52°20' W., to 45°50' N., 48°00' W. On 

 this same date, drift ice reached its maximum easterly limit of the 

 season in 46°30' N., 45°35' W. For March the entire northern part 

 of the Grand Banks was covered by drift ice varying from loose drift 

 ice at its southern limits to close pack ice at the northern extremity 

 of the 100-fathom curve and covering an area from 50 miles seaward 

 of the 100-fathom curve to the east coast of the Avalon Peninsula. 

 Its southward progress was continuous throughout the month and the 

 northern half of the Grand Banks was covered by pack ice on the 23d 

 when its southern limits were defined by a line from 46°00' N., 

 52°00' W., to 44°30' N., 49°00' W., to 45°30' N., 48°40' W. Patches 

 of pack ice drifted as far south as 44°00' N., on the 28th and 43°20' N., 

 on the 31st. 



Ice conditions along the east coast of the Avalon Peninsula were 

 essentially the same as those in February with drift ice extending at 

 times south of Cape Race to 46° 10' N., and disappearing from the coast 

 by the end of March. Very little appeared to the west of Cape Race 

 except for some slush and sludge reported on the 6tli in the vicinity of 

 Cape Pine. From the 8th of March on reports of ice in Cabot Strait 

 increased in frequency. On this latter date the limits were from Sca- 

 tari Island to 45°30' N., 59°35' W., to 45°36' N., 57°45' W., to 46°00' 

 N., 57°10' W., to 46°55' N., 57°45' W., to Cape Ray. Its maximum 

 seaward extension for the month occurred on the 21st when it reached 

 the vicinity of 44°20' N., 57°00' W. It remained in this vicinity 

 until the 28th when its southeastern limits were from 44°30' N., 

 58°40' W., to 44°35' N., 57°30' W., to 45°00' N., 56°50' W. 



It is estimated that 61 bergs came south of 48° N., in March. The
