A multi-scale geomorphometric approach to semi-automated classification of seabed morphology of a dynamic and complex marine meander bend

Seabed geodiversity comprises abiotic seabed structures and functions that form valuable natural resources, foundation for benthic habitats and marine ecosystems, and requires knowledge based, sustainable management. Geomorphological mapping involves delineation of surface features based on form, material composition and formative processes. We present an approach that applies methods of scale analysis and geomorphometric classification to characterize seabed morphology and interpretation of geomorphic units in a dynamic and complex marine meander bend. Seabed morphology was delineated using the morphometry as template supported by the DEM and associated surface derivatives. The seabed morphology served as input to an interpretation of geomorphic units applying a fluvial classification scheme in channelized marine settings. We demonstrate the potential of using a (semi-) automated morphometric classification scheme to support the characterization of high-resolution seabed morphology based on descriptive definitions and the potential of translating a fluvial classification scheme in channelized marine settings.

Data and sample collection was carried out in 2015 and 2016 as part of the MSc course “Marine Geoscience”, a joint MSc course between the Department of Geosciences and Natural Resource Management at the University of Copenhagen (IGN-KU), Department of Geoscience at Aarhus University (IG-AU), and the Department of Marine Geology at the Geological Survey of Denmark and Greenland (GEUS). The MSc courses were partly funded by Geocenter Denmark. Moreover, this work was part of the research project “ECOMAP – Baltic Sea environmental assessments by innovative opto-acoustic remote sensing, mapping, and monitoring”, supported by BONUS (Art 185), funded jointly by the European Union (EU), the Federal Ministry of Education and Research of Germany (BMBF), the National Center for Research and Development of Poland (NCBR), and the Innovation Fund Denmark (IFD).

The grain size distributions along the outer bank showed a fining and sorting trend towards north indicating sediment transport in that direction. This finding was supported by the investigation of Kuijpers (1980) .
