Maintenance and Update Frequency: asNeeded Statement: An ongoing collaboration between geoscience agencies in the United Kingdom (British Geological Survey), Norway (Geological Survey of Norway), Ireland (Geological Survey Ireland and University College Cork) and Australia (Geoscience Australia) has focused on developing a new standardised approach to classifying seafloor geomorphology. Dove et al (2016) initially described a two-part approach for mapping the geomorphology of the seabed. Part 1 is intended to guide the mapping of the seabed surface shape (Morphology), and Part 2 is intended to classify these shapes with their geomorphic interpretation. ·Part 1 (Morphology: Dove et al., 2020) is available as an open access glossary. It contains an illustrated list of terms and definitions that primarily draw on the well-established International Hydrographic Organization standard. Morphology maps can be created by applying Part 1 Morphological terms to bathymetry data. ·Part 2 (Geomorphology) is described in this report. Geomorphic units are structured within geomorphic Settings and Processes and (consistent with Part 1) these terms are primarily sourced from established literature. The application of this second mapping step requires further seabed data and/or contextual information and expert judgement, and is intended to constrain the uncertainty that is inherent to subsurface interpretation to this step. Purpose To support internationally consistent classification and mapping of seafloor geomorphology Maps of seabed geomorphology derived from bathymetry data provide foundational information that is used to support the sustainable use of the marine environment across a range of activities that contribute to the Blue Economy. The global recognition of the value of the Blue Economy and several key global initiatives, notably the Seabed 2030 project to map the global ocean and the United Nations Decade of Ocean Science for Sustainable Development, are driving the proliferation and open dissemination of ...
