Recently, the echosounder systems in the Bulgarian Black Sea shelf have become a standard method of seabed exploration. The paper presents the present-day field activity of bathymetric research, which revised available hydrographic data for the seabed. The study aims to combine and update archival bathymetric data from contemporary multibeam echo-sounding scanning and archive single-beam data. This work presents activity in the second stage of Project -Multidisciplinary study of Burgas Bay - MidBay. (Composition o...

The intensive development of remote sensing and unmanned aerial vehicles, and the accessibility of small drones, provide excellent opportunities for shallow water bathymetric surveys on the northern Bulgarian Black Sea coast. The combination of erosional/abrasional and depositional natural coastal types allows testing and assessing the efficiency of aerial surveys for bathymetric mapping. The Bay of Chernomorets is an excellent opportunity to combine data from single-beam sonar, multi-beam sounding and shooting wi...
