Modern Mapping of the Seabed Relief Using the Example from the NE Black Sea

Data on seafloor bathymetry are necessary for marine geology and geomorphology, cartography and paleogeography, geoecology and hydroacoustics, and other applied research areas. Bathymetric surveys within the framework of the fifth stage of the comprehensive coastal-marine expedition “Black Sea” on the R/V Ashamba in 2020 were carried out to solve the task of monitoring coastal bottom communities at two detailed study sites: near Cape Maliy Utrish and near Golubaya Bay. The main reason for the research was the significant discrepancy between the bathymetric data obtained at the control points and the navigational charts and data from bathymetric models. The conducted work allowed for clarifying the structure of the seabed relief of the study areas.
