Abstract

The use of spatial analytical techniques for describing and classifying seafloor terrainhas become increasingly widespread in recent years, facilitated by a combination of improvedmapping technologies and computer power and the common use of Geographic Information Systems.Considering that the seafloor represents 71% of the surface of our planet, this is an important steptowards understanding the Earth in its entirety. Bathymetric mapping systems, spanning a varietyof sensors, have now developed to a point where the data they provide are able to capture seabedmorphology at multiple scales, opening up the possibility of linking these data to oceanic, geological,and ecological processes. Applications of marine geomorphometry have now moved beyond thesimple adoption of techniques developed for terrestrial studies. Whilst some former challengeshave been largely resolved, we find new challenges constantly emerging from novel technology andapplications. As increasing volumes of bathymetric data are acquired across the entire ocean floor atscales relevant to marine geosciences, resource assessment, and biodiversity evaluation, the scientificcommunity needs to balance the influx of high-resolution data with robust quantitative processingand analysis techniques. This will allow marine geomorphometry to become more widely recognizedas a sub-discipline of geomorphometry as well as to begin to tread its own path to meet the specificchallenges that are associated with seabed mapping. This special issue brings together a collection ofresearch articles that reflect the types of studies that are helping to chart the course for the future ofmarine geomorphometry.
