OBSERVED ICE CONDITIONS AND THE ENVIRONMENT 



In order to permit timely publication of the 

 Ice Patrol Bulletin each year, as well as be- 

 cause the Ice Patrol operates on a seasonal 

 cycle from September through August, iceberg 

 statistics published in this Bulletin are pi'e- 



sented for an annual cycle of September to 

 August. To permit comparison with previous 

 years, iceberg statistics reflecting this change 

 for the years 1900-1968 are presented in Table 

 3.
