The shipborne sea-ice condition observations in the Arctic basin during the summer 2021

The paper deals with the results of data processing of the shipborne sea-ice condition observations during the nuclear icebreaker «50 let Pobedy» summer cruises in 2021. The sea-ice observations have been made in Arctic Basin between the Franz Josef Land and the North Pole. The latitudinal distribution of the first-year and old ice concentrations along the ship route is shown. The level ice thickness estimates are obtained from visual and instrumental sea-ice observations via the digital television complex.
