Development of the method of special ship ice observations

Since the middle of the XXth century researchers at the Arctic and Antarctic Research Institute (AARI) have been carrying out special ship ice observations in the Arctic and other freezing seas. Field data about main sea ice parameters are necessary for developing and validation of sea ice forecasts and satellite information. In keeping with technological advances and new research and practical tasks this method is ever developing. In spring 2023 sea ice observations were organized by the AARI’s reseachers onboard the nuclear icebreaker 50 let Pobedy in the south-western part of the Kara Sea. This paper presents recommendations concerning the method of special ship ice observations as developed during the expedition: dispatch to the vessel of operative and forecast hydrometeorological information from the AARI with a request for return transfer to the AARI of the processing results of the data obtained in the areas of predicted high deformation of ice cover along the route of navigation and upgrade of the ship television complex to receive information about ice layers and structure.
