A Field Study of the Physical Properties, Response to Swell, and Subsequent Fracture of a Single Ice Floe in the Winter Bering Sea.
Surface strain and vertical heave response experiments were conducted for a single floe within the marginal ice zone of the winter Bering Sea. The strain was measured using an array of three strainmeters placed in a 120 deg rosette configuration, and the heave was computed from simultaneous records...
