Information - GM6.2 Seafloor expression of tectonic and geomorphic processes (co-listed in GD, SSP & TS)
Bathymetry records and preserves a wealth of information about tectonic (e.g. fault scarps), geomorphic (e.g. channel erosion & landsliding), volcanic and geodynamic processes. New bathymetry (e.g. multibeam), especially when combined with sub-seafloor measurement, provides an exciting opportunity to combine geomorphology & 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 scales from ocean-wide (e.g. lithospheric cooling) to abyssal hills at the scale of meters, and datasets from satellite-predicted to multibeam 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. Perhaps: Hot-spot ridge interaction; Submerged glacial geomorphology; Quantifying underwater volcanoes; What stops subduction earthquakes – seafloor features?
