Abstract
The changes are considered in the computation and map representation of the scattering index (SI) of thick first-year ice identified from the MTVZA-GYa radiometer data. For the first time improved ice SI maps enabled detecting the zones of the low values of sea ice SI which were steadily formed in the same areas over the Lomonosov and Gakkel ridges. It is demonstrated that the intense local ice drift formed under the influence of the vortices flowing around seamounts, may be a reason for the formation of such zones. The cases are considered when the zones of the low values of ice SI were of synoptic scale (up to 1200 km) and could have been the result of the independent influence of the vortices flowing around seamounts and strong surface wind. The utility of new SI maps is noted for monitoring the areas where the vortices flowing around seamounts may considerably modify propeties of the sea ice cover.
