The doctoral candidate successfully defended a dissertation focused on the analysis of the post-Caledonian sedimentary cover structure in the Polish sector of the Baltic Sea, utilizing newly acquired seismic data from the BalTec project. The processing of seven seismic profiles, covering approximately 1,000 km, enabled a detailed study of the rock and sediment layers and facilitated the verification of the hypothesis regarding seabed contamination by hydrocarbons.

Detected structures, such as gas chimneys and bright spots, confirmed the presence of gas and migration pathways in the area of the Gryfice Block and the Trzebiatów Fault Zone. The study also highlighted the Koszalin Fault's crucial role in tectonic processes in the Mesozoic and Cretaceous periods.

The dissertation was reviewed by three experts: Dr. Edyta Puskarczyk from AGH University of Science and Technology, Dr. Iwona Stan-Kłeczek from the University of Silesia, and Dr. Erika Barison from OGS, Italy. The reviewers agreed on the high quality of the analyses and the innovative approach to reprocessing archival data, noting it as a valuable contribution to the development of research methods in marine geology. The dissertation results are applicable to both geological research and hydrocarbon resource assessment as well as environmental protection. The defense was successful, and the candidate received a positive evaluation and recommendation for the conferment of the doctoral degree.
