 REGION AND THE LABRADOR SEA IN 1963 ^ 



By Alfred P. Franceschetti, V. W. Drigsers, and R. M. O'Hagan, U.S. Coast Guard 



The 180-foot tender class cutter USCGC Evergreen was again the 

 oceanographic vessel of the International Ice Patrol for the fieldwork 

 of 1963. 



The Evergreen departed Woods Hole on 26 March to conduct the 

 first oceanographic survey of the 1963 season. The survey covered 

 the waters over and immediately seaward of the southern and eastern 

 slopes of the Grand Banks from just westward of the Tail of the Banks 

 northward to section T, approximately 45°-40° N. The work of 

 collection of data began at station 8387, located off the southwestern 

 slope of the banks, on 30 March and progressed from south to north 

 to station 8443 along section T when on 8 April, because of a fathom- 

 eter breakdown and the proper replacement parts not being immedi- 

 ately available, the survey was stopped and the Evergreen proceeded 

 to Argentia, arriving on 10 April. 



The second survey covered the waters over and immediately seaward 

 of the eastern and northeastern slope of the Grand Banks from section 

 T where the first survey was stopped and included Flemish Cap and 

 the Bonavista triangle. The work of collection of data began at 

 station 8444 on 15 April and progressed from south to north with 

 the final station, No. 8543, being completed on 25 April. The Ever- 

 green then proceeded to Argentia, arriving there on 27 April and after 

 an overnight layover proceeded to Boston. 



A combined third and fourth survey similar to the first and second 

 was conducted as one survey. The Evergreen departed Boston, Mass., 

 on 11 May to begin the third current survey, arriving on station, No. 

 8544, on 14 May. The collection of data was completed on 31 May 

 at station 8697 whereupon the Evergreen proceeded to Argentia, 

 arriving on 2 June. After a brief stop, the Evergreen then proceeded 

 to Boston. 



In addition to the normal postseason survey consisting of the 

 Bonavista triangle and Labrador Sea section between South Wolf 

 Island, Labrador, and Cape Farewell, Greenland, the Evergreen 

 collected oceanographic data in Kennedy Cliannel, Kane Basin, Smith 

 Sound, and Upper Baffin Bay. The report of this survey will appear
