figure 7 and S for the distribution of ice to Cape Chidley, Labrador. 

 Figure 8 was compiled from P]SSA I data transmitted to the Ice 

 Patrol by the U.S.C.G. Oceanographic Unit, Washington, D.C. 



The winds were predominantly onshore over northern Newfound- 

 land and Labrador, containing the pack ice and a few bergs along 

 the coast. On the 3d, 11th, and 31st. three low pressure systems with 

 winds in excess of 40 knots greatly aided containment and deteriora- 

 tion of pack ice and bergs along the I^abrador coast. 



The 1966 season had been defined in December 1965-January 1966 

 on the basis of the surface pressure patterns and observed distribution 

 of bergs to Cape Christian, Baffin Island. The continued predominance 

 of southerly and onshore winds insured the continued absence of ice. 

 During the last week of March it was decided to end the Patrol as 

 soon as it became completely evident that southward berg drift into 

 tlie shipping lanes was improbable. The pattern was established and
