Figure E-6. COMPARISON OF ICEBERG DETERIORATION PROCESSES. This figure graphically de- 

 scribes both the significance of each process and the affects that different parameters have on the "melt" 

 contribution for these processes. The "melt" contributions, which are denoted by a (•), are the five-day 

 average for a cluster of four medium-sized, non-tabular icebergs. An (X) denotes the minimum and maxi- 

 mum five-day average for an individual iceberg. A (I) denotes the minimum and maximum daily "melt" for an 

 individual iceberg.
