Abstract
In March 2007 the field campaign FRAMZY took place in the region between Spitsbergen and Greenland. One goal of the experiment was the observation of cyclone impact on ice drift by means of autonomous meteorological buoys, deployed on sea ice. On 23 March an intense cyclone, of about 500 km diameter, passed with about 20 m/s from south to north over the ice-covered part of the Fram Strait and induced strong inertial oscillations of the sea ice. Ice-drift velocity fluctuations abruptly increased by a factor of three to values of more than 1 m/s. This was caused by a resonant wind forcing for almost three quarters of the inertial oscillation. Depending on the local ice conditions the oscillations lasted over a two to five days period. The inertial oscillations caused ice drift divergence fluctuations of +/- 6 . 10(-6) s(-1) and a reduction of ice concentration by up to 11%. Citation: Lammert, A., B. Brummer, and L.
