F^GUKE 23. — Ice condition Grand Banks on 19 May 1964. 



The deterioration of the many bergs on the Grand Banks was com- 

 paratively slow due to abnormally cold sea temperatures. See figures 

 51 and 52, normal charts for May and figures 5 and 6, this year's May 

 isotherm charts. The bergs in the wanner waters of the southern 

 and central Grand Banks were the first to perish while those bergs 

 in the colder coastal waters and colder waters near or in the Labrador 

 Current persisted longer. On 22 May, 80 bergs remained south of 

 48° N. and the southern limits of bergs on the central Grand Banks
