The data received by IIP shows that, of 

 all the ice charts received, 94% had at least the 

 LAKI and date readable. Assuming that the 

 sample of 82 charts received is fairly 

 representative of the larger population of HF 

 received charts, this level of usefulness is 

 promising. The data also shows that more than 

 53% of all ice charts were received on 9110 

 MHz (Table 2). The fact that the US Coast 

 Guard transmits the chart on the most used 

 frequency shows that the customer of the ice 

 chart finds the US transmission satisfactory. 

 The most used frequency found during this 

 survey differs from that found during the 2000 

 survey in which 12750 MHz ranked the 

 highest. Interestingly, the percentage of the 

 charts received at the 12 MHz frequency also 

 represented 53% of the sample (Dale and 

 Strong, 2000, p. 53)*. Based upon the 

 combined data for both studies, it can be 

 inferred that the higher frequencies generate a 

 better, more reliable product for the mariner. 



This study, when considered in 

 conjunction with that of 2000, shows that the 

 HF WEFAX ice chart remains a viable and 

 trusted product dissemination method. Surveys

of this nature, in addition to the customer 

 satisfaction survey planned for 2004, give the 

 Ice Patrol a real insight into customer feelings.
