ABSTRACT
An assessment of ice and iceberg spreading based on expedition in 2001 and 2003 changed significantly the knowledge of the possible number of icebergs reaching the southern area of the Barents Sea. This study motivated us to set-up an iceberg drift model for this region. It gets ocean and sea-ice input from a HYbrid Coordinate Ocean circulation Model including tides, of 10-km grid cell resolution. Preliminary validation of the model, based on observations obtained under the Ice Data Acquisition Program in 1989 is presented. We focus on the relative importance of the dynamic interaction between an iceberg with the atmosphere, the ocean and its surrounding sea-ice dynamics to reproduce the observed iceberg drift patterns.
