Submarine landscapes, from coastal environments to the deep ocean, are shaped by the complex interaction of geological, oceanographic, biological, and anthropogenic processes acting across a wide range of spatial and temporal scales. Seafloor morphologies therefore represent fundamental archives of past and present Earth system dynamics, recording the combined effects of tectonics, sedimentary processes, fluid circulation, volcanism, and oceanographic forcing. At the same time, they provide valuable insights into the future evolution of submerged environments and the assessment of offshore geohazards. Understanding the processes that shape and modify underwater landscapes is essential for advancing quantitative geomorphology, improving geohazard evaluation, and supporting the sustainable management of marine systems. This interdisciplinary session highlights recent advances in the study of seafloor and sub-seafloor systems, with a focus on geomorphological and tectonic processes controlling marine landscape evolution. Topics include sediment-gravity flows, current-driven transport, landslides, tectonic deformation, volcanic activity, and fluid migration and escape. Contributions are welcome from a broad range of subaqueous environments, from coastal zones to shallow- and deep-sea settings. Studies based on integrated, multi-scale datasets are particularly encouraged, including hydroacoustic, satellite-derived, seismic, geophysical, sedimentological, geochemical, and ROV-based observations. By integrating diverse approaches and datasets, the session aims to promote a comprehensive understanding of submarine landscape evolution and strengthen links between geomorphology, tectonics, geohazards, resources, and ecosystems.
