of the ice patrol board as just described. Certain conclusions based 

 on these data were published in the International Ice Observation 

 and Ice Patrol Service Bulletin Xo. 11, which gives the most com- 

 plete information of its kind, regarding conditions existing in the 

 ice regions. This season, in view oi:" the amount and type of data 

 previously collected, it Avas decided that more information could be 

 added to our ever increasing store by recourse to no set program of 

 sections, but rather that places and events should to a great uu^asrae 

 decide the course of investigation from time to time during the 

 season of 1924. In a few instances lines of stations have been made, 

 but a brief survey of the order of the oceanographical work this 

 year will be of benefit to the reader. 



March 22-31, five stations (377-382)^^ were occupied around the 

 seaward face of the Grand Banks, beginning at a point on the slope 

 80 miles northwest of the Tail and extending up the eastern side of 

 the Bank to parallel 44° 50' north. The stations were selected in 

 critical positions on the edge of the Bank where normally during 

 previous ice seasons we have found the heart of the arctic water. The 

 first task of the ice patrol vessel arriving in the ice regions is to 

 make a general survey of conditions by searching the area most 

 liable to contain ice and also determining, if possible, the intensity 

 and extent of arctic circulation by means of oceanographical observa- 

 tions. Stations 377-382, as will be seen later, assisted to cast light 

 on the degree of arctic invasion in March, 1924. Station 383 was 

 located in on the central part of the Bank. April 1-5^^ we took 

 stations at intervals southward past the Tail and into warm Atlantic 

 water as the patrol ship followed the course of berg No. 2.^^ Stations 

 389-394 constitute profile No. 1, a line running north and south of 

 the Tail: while stations 395-399 follow northward along the eastern 

 edge of the Bank to the forty-sixth parallel. 



During the next two weeks, April 15-30. a total of 30 stations were 

 worked, as follows: 400-405 is a section from the northern part of 

 the Bank, running northwest across the "' Gulley '' to Cape Kace. 

 (See profile No, 2.) Stations 406 and 407 were located in Trepassy 

 Bay to determine the possible presence and intensity of arctic water 

 in that locality. We next ran a line (stations 408-417, profile No. 3) 

 from Cape Eace southwestward into the deep water of the Laurentian 

 Channel, the purpose of which was to gain information regarding 

 the probable distance southwest of Cape Race to which arctic water 

 extended at this time of year. Stations 418-423 were taken April 

 23-24 along the southwest slope of the Grand Bank and up the east 

 side, similar to the investigation made of these waters about a montli
