Based on a combined analysis of measurements obtained from unmanned aerial vehicle (UAV), spaceborne synthetic aperture radar (SAR) and in situ measurements, an assessment of the small-scale and submesoscale dynamics in the marginal ice zone (MIZ) in two regions of the Kara Sea was made. The measurements were performed at two ice polygons located in the eastern part of the Kara Sea in August 2021 during the 58th cruise of the RV Akademik Ioffe. The depths of the brackish layer varied from 0.5 to 2.5 m. Analysis of near-surface salinity measurements from ship-mounted flow analyzer showed the meandering of brackish areas associated with uneven ice melting. Based on spaceborne SAR observations, eddy features in the MIZ and the evolution of the MIZ were described. Possibilities of using serial UAV for studying the small-scale dynamics of the MIZ are demonstrated. A pronounced anticyclonic eddy was found at one of the polygons in the field of drifting ice. The values of the ice velocity modulus in the anticyclone calculated from UAV measurements reached 0.7 m/s and were primarily associated with the dynamics of the upper ocean layer, and not with the wind effect. An analysis of the reconstructed ice drift kinematic characteristics from UAV data and wind measurements at the stations showed the key role of the ageostrophic component in the ice drift velocity field.
