20. ABSTRACT (Conllnua on ravaraa alda II naeaaaary and Idantlty by block numbat) 



Temperature and salinity measurements were made in and near the ice in the 

 Chukchi and Beaufort Seas with a continuously profiling instrument in August 

 of 1971 and 1972 as part of the MIZPAC Program. Warm water of Bering- Sea 

 origin was found south of the ice in all of the area surveyed, layered sharply 

 on top of cold water. Complex temperature and sound-velocity profiles were 

 found near the Alaskan Coast north of the ice margin, diminishing in intensity 

 toward the interior of the ice pack but still noticeable (r.nntiniiFiri nn harlf^
