Abstract—New data on the geological structure and genesis of relict bottom relief forms, objects of underwater cultural heritage, and the structure of bottom sediments in the Baltic Sea were obtained during cruise 47 of the R/V Akademik Nikolaj Strakhov (June 25–July 4, 2020). Geomorphological features of submerged ancient coastal cliffs have been specified, large sand bodies have been identified at depths of 15–30 m, the iceberg origin of furrows has been confirmed, buried paleoincisions have been identified, gas chromatographic analysis of gas-saturated sediments has been performed, and a search for submerged objects has been carried out.
Keywords: Baltic Sea, relict landforms, iceberg ploughmarks, palaeoincisions, pockmarks, gas-saturated bottom sediments, sunken objects
