On 1 ]May the quiet weather came to an end. By noon it was too rough 

 to carry out the GEK jog pattern and by 1210 it was necessary to 

 heave to. At 0400 the next morning it was possible to proceed toward 

 the next station, 5868, but progress was slow and the GEK progi'am 

 could not be resumed until nearly noon on 2 May upon departure from 

 station 5870. No fm"ther extended delays were encountered and the 

 last station, 5877, was completed on the morning of 3 Alay. The 

 Evergreen then proceeded to Argentia, arriving there on 4 May, 

 During the sm'vey 50 stations were occupied. 



The Evergreen proceeded to Boston, where repairs to the heating 

 boiler and evaporator were accomplished, and then returned to Argentia. 

 On the morning of 1 June departure was taken from Argentia for the 

 purpose of making a survey of the area northward of the Grand Banks. 

 The northern limit of the survey was set at about the latitude of the 

 Strait of Belle Isle and was determined by the southern limit of the 

 sea ice. The eastern limit of the survey was far enough east to include 

 the eastern margin of the Labrador Current and to include an adequate 

 number of deep water stations to serve as reference stations for the 

 numerous sections of anomaly of specific volume necessary for the 

 determination of the dynamic heights of the shallow water stations. 

 The Bonavista triangle Avas included in this survey and a network 

 extended the surveyed area from the triangle to Flemish Cap. The 

 work of collection of data began at the offshore end of the northernmost 

 section, station 5878, on the morning of 3 June and progi-essed from 

 north toward south. Very nearly ideal conditions of wind and sea 

 prevailed throughout the survey and no delays were encountered other 

 than that occasioned by the necessity of skirting the edge of field ice 

 along the northern and western edges of the surveyed area. The 

 collection of data at the 106 stations comprising the survey was com- 

 pleted on the morning of 14 June at station 5983. The Evergreen then 

 proceeded to Ai'gentia, arriving there on 15 June. 



On 17 June the Evergreen proceeded to Boston and on 7 July de- 

 parted Boston to begin the post-season cruise. This was to consist of 

 the occupation of the Bonavista triangle and a section across the Lab- 

 rador Sea from South Wolf Island, Labrador, to Cape Farewell, Green- 

 land. The work of collection of data began at station 5984 at the 

 off-shore corner of the triangle on the morning of 11 July and progres- 

 sed without incident, working around the triangle in a counter-clock- 

 wise direction to the point of beginning and completing the work of 

 collection for the triangle at station 6013 on the morning of 14 July. 

 South Wolf Island was reached on the morning of 15 July and the 

 work on the section across the Labrador Sea progi-essed without inci- 

 dent until station 6036 where field ice was encountered about 10^2 miles 

 off Cape Farewell. Visual and radar observation confirmed the ex- 

 pectation from the previous several days of on-shore winds that the 

 coastal belt of ice would be compact. Thus the work of collection of
