Gulf Ice Charts 1942

1942 Season

Normally, navigation may be expected to open up across the Gulf of St. Lawrence to the mouth of the St. Lawrence River about mid-April, the route becoming ice free prior to 10 May. In 1942 the ice in the central gulf broke up rapidly between 29 March and 4 April. On the latter date the shipping track from Cape Ray to Fame Point was navigable and the ice broken to Quebec. The next day the Cape Ray to Fame Point track was clear. Ice persisted S of Anticosti Island, and in the southern part of the gulf in the vicinity of PEI until early May. From time to time during April occasional patches of this ice drifted across the shipping track between Fame Point and Cape Ray but did not close it. On 22 April the St. Lawrence River was open to Montreal. On 6 May all gulf routes from the S were sufficiently clear of ice to permit discontinuing the ice surveys in that area. Excluding the northeastern section of the gulf near the Strait of Belle Isle, two bergs were reported.

On the banks SW of Nova Scotia and Cape Breton Island the southern extremity of the pack during March and April could usually be found between 44°30’N and 45°30’N. The ice never extended as far as Sable Island, and on only two occasions was there any threat of the ice forcing inshore traffic to the S of that island. The westerly extension of the ice stopped short of Halifax. Traffic E from that port was little inconvenienced by the ice and if so desired could always be routed S of the ice and N of Sable Island.

Light patches of ice were reported in the vicinity of Louisburg until 4 May, after which no more ice was reported S of the gulf. (IIP 1946 p1)
