Abstract
This publication presents a study focused on identifying shores with archaeological settlements submerged at depths of 2–3 meters in the northwestern Black Sea shelf, specifically around the Dnipro Estuary. The primary research method utilizes satellite technologies from the Sentinel-2 mission, applying combinations of spectral ranges using water index formulas (NDWI, MNDWI, NDTI). While satellite data can effectively detect water and underwater objects, limitations exist, such as dependency on weather conditions for multispectral data, challenges in accurately delineating boundaries, as well as seasonal and periodic changes and water turbidity caused by vegetation or algal blooms, particularly in shallow areas, etc. By employing specific conditions and image processing techniques outlined in this study, we successfully identified flooded paleo-banks with high pixel contrast, which will greatly enhance the search and examination of archaeological findings and sites classified as cultural and historical heritage of Ukraine.
