Linear sea ice canopy fractures (leads) and ice floe rotation appear to be interrelated. This study focused on a highly persistent storm wind event. As the wind stress increased over the ice pack, a separate rotation threshold for four floe-attached buoys was observed. The northwestern-most buoy recorded the start of clockwise ice-floe rotation just as hydrophones recorded increased oceanic ambient noise. Several days later, when the surface wind speeds and computed stress at all four buoys dropped to ~60% and e-1 of their respective peak storm values, a counterclockwise rotation began at each buoy with a concomitant impulsive ambient noise peak. The rotationally-induced ''noise bursts'' are called icequakes in an analogy with earthquakes. ¿ American Geophysical Union 1996
