Winter Ice Dynamics in a Semi-Closed Ice-Covered Sea: Numerical Simulations and Satellite Data

The White Sea is a small shallow sea covered by ice in winter. There are very few numerical models of this sea. For the ice-free sea, much data has been collected, but for winter only amount (satellite only). We use our finite-element model Jasmine and satellite to trace advection exchange between parts Sea. aim investigation adjust adequately reproduce dynamics. By comparing on sea-ice concentration with prediction, we show that describes dynamics well, it estimate flow from bays middle part through narrow strait. Ice neighbouring shown be intensive, large dispersion compared time-mean, producers, while Gorlo straight accept ice. demonstrate tool can used better understand regime
