AbstractA new iceberg drift, deterioration and calving model has been under development at the Canadian Ice Service (CIS). The model includes several new features including the utilization of detailed environmental forcing input, and a robust implicit numerical solution method. In particular, the vertical distribution of water current is incorporated in calculations of water drag force on the iceberg keel. The model is also the first to include treatment of calving, prediction of calved ice piece size distribution and deterioration, as well as the drift of calved pieces. This paper gives a description of the drift model formulation, and verification tests that include comparisons of model predictions with field observations. Additionally, the paper presents the outcome of a parametric study aimed at examining the sensitivity of iceberg drift to input parameters and environmental forcing. Tests examined the role of water and air drag coefficients, water current, wind waves and the waterline length of the iceberg. A number of scenarios of input water current, and wind drag force were also considered. The results determine the impact of the input parameters and variables on predicted iceberg tracks.
