Abstract—A shipborne lidar survey of the western Kara Sea was carried out. The study was performed as part of the first stage of cruise 89 of the R/V Akademik Mstislav Keldysh in September 2022. Simultaneously with the lidar survey, a set of accompanying hydrooptical and hydrological measurements was carried out. Joint statistical analysis of the obtained data made it possible to obtain regression relationships between the lidar attenuation coefficient, seawater beam attenuation coefficient, and diffuse attenuation coefficient. These regression relations are used to convert the spatial distribution of the lidar attenuation coefficient into the seawater beam attenuation coefficient values.
