Appendix C 



International Ice Patrol Iceberg Size Classification 



MST2 Sheridan B. McClellan 

 International Ice Patrol 



Background 



It was recently discovered that there existed a slight difference between the iceberg size 

 classifications listed on the IIP website and in chapter 4 of the MANICE manual. The tables 

 below are taken directly from the IIP website and from the MANICE manual: 



Table 1: (IIP Website) 



Table 2: (MANICE Code) 



As seen above in the highlighted areas, the differences are small but cannot be accounted 

 for as rounding errors in the conversion from feet to meters. In addition, no distinction in iceberg 

 shape is made in either table. For consistency, IIP has decided to adopt the MANICE size 

 descriptions for all future use. Prior to making this decision, the following information was 

 gathered regarding HP's legacy iceberg sizing chart.
