Seafloor depth records preserves a wealth of information about tectonic (e.g. fault scarps), geomorphic (e.g. channel erosion and landsliding), volcanic and geodynamic processes. High quality bathymetry, especially when combined with sub-seafloor measurement, provides an exciting opportunity to combine geomorphology and geophysics and to extend quantitative geomorphology offshore.

This interdisciplinary session aims to examine the causes and consequences of the underwater landscape. The goal is to stimulate interdisciplinary work by bringing together researchers who quantify and characterize the shapes that form the seafloor, seek to understand the sub-surface processes at work and their impacts, or use bathymetry as a model input. A range of depths from oceanic (e.g. oceanic plateaus and abyssal hils), through mid-ocean ridges to accretionary wedges and continental margin are expected. Datasets from satellite-predicted depth to ultra high-resolution deep tow swath are anticipated.

We welcome any exciting submissions in the spirit of the session, even if your particular process or bathymetric expression has not been explicitly mentioned, e.g.: Hot-spot ridge interaction; Submerged glacial geomorphology; What governs the relative dominance of canyon erosion and landsliding as mass wasting processes?
