Multiparametric Subaqueous Dataset for the South Baltic Sea: Lubiatowo case study
Magdalena Stella-Bogusz
Abstract. This study presents bathymetric and side-scan sonar surveys conducted in the remote nearshore zone of the southern Baltic Sea, approximately 1–2 nautical miles offshore near Lubiatowo, at water depths of 16–20 m. Measurements were collected during five field campaigns in November 2017, December 2018, and three in 2023 (April, September, and December), and processed to generate detailed bathymetric maps and sonar mosaics. These maps accurately reflect seabed conditions and highlight morphological changes over time.
In addition to the bathymetric surveys, divers performed seabed observations, documented bedform appearances, and collected seabed soil samples for grain size analysis. Underwater videos and photographs were captured using an underwater drone equipped with a ruler, ensuring precise measurement references.
The analysis includes differential bathymetric maps showing seabed elevation changes ranging from a few centimeters to more than 1 m over time intervals spanning several months to multiple years. Sonar imagery and subaqueous photographs document ripple fields and other seabed features of varying scales, providing complementary information for interpreting seabed morphology.

This paper presents a long-term, high-resolution dataset showing how the sea floor changes over time in the southern Baltic Sea near Lubiatowo. Based on five surveys carried out between 2017 and 2023, it shows that the sea floor remains active even in deeper water, with elevation differences reaching 1.35 metres, and records a wide range of sea floor patterns. The dataset supports future coastal monitoring, environmental studies, and offshore planning.
