On the issue of reconstruction of the water area of the Tauric Chersonesos seaport in Karantinnaya Bay
While reconstructing changes in sea level and the lost territory of Chersonesos, based on modern bathymetric marks, it is necessary to take into account the thickness of the bottom ground layer formed during the period under consideration. These estimates must be verified by archaeological data obtained during research in the bays of the Heraclean Peninsula. Excavations in Karantinnaya Bay, in the area of the "rhomboid tower", revealed that the base of the flooded structure, corresponding to the sea level at the time of its construction, was buried under a layer of sediment more than a meter thick. The bottom ground is largely composed of imported, possibly ballast, material, which suggests a harbor or port. The estimation of the sea depth change in this area is about 2,86 m, the coast has receded by at least 30 m. The presence of the accumulative form on the 1808 map allows us to shift the possible localization of the Chersonesos harbor north of the modern school of divers near the western coast of Karantinnaya Bay.
