Figure 7. Count of individual icebergs (sighted and 

 drifted) south of 48 N since 1998. The climatologicai 

 (three year) mean is 603 icebergs. 



In the effort to classify ice season 

 severity, various authors have discussed 

 the appropriate measurements and criteria 

 (Alfultis, 1987; Trivers, 1994; and Marko, e\ 

 a/., 1 994). Comparing 2002 to the past five 

 years and measuring the statistics against 

 historical ice patrol data, 2002 was 

 moderate in terms of season length and 

 extreme in terms of the number of icebergs 

 south of 48°N. Trivers (1994) defined an 

 extreme ice season as one where more 

 than 600 icebergs drifted south of 48°N. 

 Trivers also defined a moderate season, in 



terms of length, as one between 105 and 

 180 days. 



Canadian Support 



The Canadian Government 

 provided a great deal of support during the 

 2002 season, as they do every year. CIS 

 conducts ice reconnaissance using a 

 SLAR equipped Dash-7 airplane, focusing 

 primarily on sea ice. Provincial Airlines is 

 a private company that provides 

 reconnaissance services on contract to 

 DFO throughout the year, to CIS from June 

 through December and to the offshore oil 

 industry. DFO flights by Provincial Airlines 

 monitor fishing vessel activity, frequently 

 carrying them into areas of high iceberg 

 concentrations. Canadian support of 

 BAPS is also an integral part of HP's 

 operations. The models are connected via 

 the internet and "speak" to each other 

 numerous times each day. For example, 

 CIS retrieves environmental data (winds, 

 waves, currents, sea surface temperatures, 

 etc.) that reside on MP's BAPS. IIP 

 receives data on icebergs crossing into our 

 AOR in a similar method.
