Modern High-Resolution Digital Elevation Model of the Kara Sea Bottom

The digital elevation model (DEM) of the Kara Sea bottom was created on the basis of multiscale navigation charts from the Department of Navigation and Oceanography of the Ministry of Defense of the Russian Federation. The errors in the created DEM and publicly available IBCAO v3 DEM were calculated using data obtained during expeditions from 2007 to 2022 in the Kara Sea. The accuracy of these two DEMs was assessed using descriptive statistical methods, demonstrating significantly better seabed relief detail in the created DEM.
