Figure E-1. Modelled Iceberg Deterioration Processes. This figure depicts four processes used by 

 ttie IIP deterioration model to "melt" icebergs. Ttie four processes, whicti are labelled in order of 

 importance are: (1) wave erosion; (2) forced tieat convection; (3) buoyant heat convection; and (4) 

 solar radiation. The figure also identifies the variable environmental terms used to model each 

 process and their influence on "melt" for the icebergs studied by IIP. These terms are: relative 

 velocity; wave height; wave period; and relative temperature. Other terms used to model iceberg 

 "melt" are: cloud cover, which is constant; and maximum waterline length of the iceberg.
