Résumé | A new operational iceberg forecasting model is under development at the Canadian Ice Service (CIS). The model deals with iceberg drift, deterioration, and calving. One of the main features of the new model is the utilization of detailed environmental conditions. In particular, the vertical distribution of water current is used to calculate water drag forces. An accurate description of keel geometry is, therefore, needed in order to take advantage of the detailed water current information. This paper describes the analyses done to determine the geometry of iceberg keels and sails. The objective was to provide refined input for the iceberg drift section of the forecasting model. Available iceberg data were used to create empirical equations which describe keel crosssectional areas at different depth intervals from a given waterline length. The equations also determine sail area, draft, and mass as functions of waterline length. This is the first investigation that determines geometry in detail. |
