Feb On the 10th of the month the limits of the field in the St. Lawrence area were observed by an ice patrol flight to be from Cape Egmont to 30 miles to the E thence to the SE to a position 38 miles E of Scatari Island and thence to St. Esprit Island. Only light sludge was present S of Cape Breton with a cover up to about 5/10ths. The outer 5 to 10 miles of the field N of Scatari Island was heavier and it is doubtful that this portion of the field was navigable. The inner portion of the field N of Scatari Island was mostly sludge with no ice present to the shoreward of a line from Cape Smoke to Flint Island except in small bays and inlets. By the 16th of the month the northeastern limits of the filed had moved such that the field now ran from a point 15 miles SW of Cape Ray to a point 30 miles E of Scatari Island and thence to St. Esprit Island. Only the seaward boundary of the field was observed on this date. It consisted of large cakes for the most part and was rather closely packed with navigation limited to specially constructed vessels. By the 26th of the month the field had progressed southwestward almost to Cape Canso, and on the 47th parallel a tongue extended to Burgeo Bank. The width of this tongue was approximately 5 to 10 miles. S of Scatari Island the outer portion of the filed consisted of small cakes with a cover ranging from 3/10 to 5/10. The inner portion was slush. Running off shore from the outer limits of the main fields were numerous patches and strings of sludge extending to the SE as far as Misaine Bank. To the N of Scatari Island the outer portion of the fields consisted of heavier ice with a cover ranging from 3/10 to 10/10 with 5/10 or more predominating. Only the outer boundary was observed on this date. (IIP p6)

Feb 26 45°10’N 59°06’W Floe of light ice about 3 miles in diameter. Southwestern limit. (IIP p26#7)

Mar The St. Lawrence ice reached its maximum southerly extension during the first week of March. During the first week the field spread as far S as 44°20’N in the vicinity of Sable Island and W to the 64th meridian just off the coast of Nova Scotia. There was a belt of slush ice to the E running from the Newfoundland coast S to the 45th parallel between the eastern boundary of the main field running along the meridian of 58°40’W and the 58th meridian. During the first part of the month the main field was light to moderate heavy winter ice. It was unnavigable, however, except for a small shore lead along the Newfoundland coast between Cape Ray and Cape Anguille. By the 19th the southern boundary had retreated to Misaine Bank and the field had narrowed considerably. The eastern boundary now ran from Cape Ray to Burgeo Bank, south to Artimon Bank and thence west to Misaine Bank. The western boundary ran from Cape Egmont SE o 46°N 59°W and thence SW to Misaine Bank. By the end of the month the outer limits of the field ice ran from Cape Ray to 46°20’N 58°30’W to 45°00’N 58°30’W and thence to Scatari Island. (IIP p8)

Apr Melting of the field ice occurred less rapidly in the St. Lawrence area [than the Grand Banks]. At the beginning of the month the outer limits ran from Scatari Island to the northern tip of Burgeo Bank, to Misaine Bank, and thence to Cape Ray. By the 17th the southern and eastern boundaries had receded and the limits now ran from a point 15 miles off Cape Ray to 46°43’N 58°40’W to 46°00’N 59°05’W and thence to Scatari Island. Between the 17th and the last week of April these limits fluctuated as much as 30 miles to the E and S. By the 19th a vessel had passed through the gulf and up the St. Lawrence River arriving in Montreal on that date. By the 30th, however, the Canadian Dept. of Transport reported that all ports in the western part of the Gulf of St. Lawrence were open to navigation. Close pack ice still remained to the NE of Cape Breton Island, the outer limits running to the NE of Cape North to 46°50’N 59°30’W to 46°25’N 58°40’W. (IIP p9)
