Analysis of the IIP Iceberg Deterioration Model. Cost and Operational Effectiveness Analysis for Selected International Ice Patrol Mission Alternatives. Annex G.
Abstract
This report is Interim Report Volume 7 for the Cost and Operational Effectiveness Analysis for Ice Patrol Mission Analysis Study. The International Ice Patrol has developed a model at iceberg deterioration that plays a critical role in the overall modeling at iceberg locations and determining the Limits at All Known Ice. The deterioration model, along with an iceberg drift model, is used to determine the location and state at any reported iceberg until it is resighted. The deterioration model depends on the reported size of the iceberg and a number at environmental parameters. This report examines the structure at the deterioration model, reviews empirical evaluations at the model, and conducts an analytical and experimental sensitivity analysis at the model outputs with respect to the model parameters. The result at this analysis suggests that the deterioration model is a reasonable representation at the actual deterioration process, lacking only a good mechanism far modeling the calving phenomenon. The sensitivity analysis suggests that there is little need for further accuracy in obtaining environmental parameters. The single most important factor in the application of the model is the initial estimate of iceberg size and the corresponding waterline length. (AN)
