Short summary
This study presents detailed underwater mapping of over 7,000 square kilometers of the Polish Southern Baltic seafloor, conducted from 2022–2023. Using seven vessels and advanced sonar technologies, we created precise maps of the seabed shape and surface characteristics with centimeter-level resolution. The unprecedented data supports marine conservation, wind farm planning, and underwater archaeology, allowing sustainable management of marine resources.
