A knowledge of sea-ice dynamics is key to achieving proper Arctic climate simulations. The goal of this thesis is to lay the foundation for a three-dimensional ice dynamics model that considers both thermal and dynamic stresses. This thesis presents in-situ observations from buoys deployed in the Canadian Arctic Archipelago (CAA). In the CAA, the sea ice is landfast for approximately six months in winter. In a first step, we have analyzed in-situ data from a sea-ice stress buoy deployed in the Viscount Melville Sound. Results demonstrate that thermal stress is the dominant source of internal stress in the CAA with few short-lived important dynamic stress events caused by ice floe collisions in the free drift season prior to the landfast sea...
