13. "How valuable are the IIP products?" 



98%-Very Valuable 

 2%-Somewhat Valuable 

 0%-Not Valuable 



14. "Please rank the importance of the IIP 

 products (1=most important, 4=least)"

NOTE: The figures presented are averages. Many 

 mariners misunderstood the question and rated 

 each product on a scale of 1 to 4. Others as- 

 signed a value to only some of the products and 

 left the others blank. Since no one can reason- 

 ably guess a response, and assigning a would 

 unfairly lower averages (thereby raising the level 

 of importance), the blanks were disregarded and 

 each product was averaged individually by divid- 

 ing its total with the number of figures it actually 

 received. The products rated instead of ranked 

 were averaged with the figures the mariners as- 

 signed them. Because of these inconsistencies, 

 the actual figures presented should not be taken 

 too literally but do provide a valid general com- 

 parison. See comment for question 5 in regards 

 to popularity of voice broadcasts. 



15. "How many transits do you make through 

 the IIP area each year during March through 

 September?" 



NOTE: 4.1 transits was the average, with 20 tansits 

 being the highest and the lowest. 



16. "Please indicate the type of vessel that you 

 usually operate." 



30% - Bulk 



18% - General Cargol 

 4% - Container 

 9% - Oil Tanker 



7% -Other Tanker 

 7% - Reefer 

 4% - Unspecified 

 3% - RO/RO 



1% - Research, Heavylift, OBO, Passenger, 



Multipurpose 

 (Less than 1%) - Fishing, Sailing, Live 

 stock, Cable Layer, LPG 



17. "Compared to conditions when there are no 

 icebergs and IIP is not in operation, please esti- 

 mate the number of extra hours of enroute time 

 that are required on an average transit to avoid 

 icebergs or to remain outside the Limit of All Known 

 Ice." 



NOTE: 16.1 Hours was the average time for the 

 100 responses to this question, with a low of 

 hours and a high of 96 hours. 



18. "Based on your experience, how accurate is 

 the Limit of All Known Ice?" 



37% - Extremely accurate (icebergs never 

 seen outside the Limit of All Known Ice) 



54% - Very accurate (icebergs occasion- 

 ally seen outside the Limit of All Known Ice) 



9% - Somewhat accurate (icebergs usu- 

 ally seen outside the Limit of All Known Ice) 



0% - Never accurate (icebergs always seen 

 outside the Limit of All Known Ice) 



COMMENTS 



A space was provided at the end of the 

 survey to allow for comments or suggestions. Al- 

 though the majority of these were left blank, 59 

 generic comments were received in praise of our 

 services and imploring their continuation. Sug- 

 gestions included involving more merchant ships 

 to do ice reporting, extending the period of ser- 

 vices, and even installing radar reflectors on ice- 

 bergs. A few comments were made in reference 

 to slightly exaggerated limits or individual icebergs 

 not being located in the positions they were esti- 

 mated to be. This suggests a tendency of some 

 mariners to mistake prognostic estimates as fact, 

 a potentially dangerous misconception we seek 

 to avoid.
