DEM of Difference (DoD) grids and bathymetric GeoTIFFs of NE Stromboli coast (Italy). Data supporting "Active sedimentary dynamics and evolution of upper-flow regime bedforms in a shore-connected channel: a case-study from Stromboli volcano."

High-resolution bathymetric datasets acquired between 2021 and 2024 are provided as georeferenced raster grids in GeoTIFF format. The dataset includes four digital terrain models (resolution of 1.5 m cell size) representing the seafloor morphology for the years 2021, 2022, 2023, and 2024. Isobaths derived from the bathymetric models are represented with a contour interval of 20 m. In addition, two dem of differences (DoDs) (2022–2023 and 2023–2024) are included to highlight temporal seafloor changes and morphological variability between successive surveys.
