This dataset contains morphological information about the corrugation ridges that were mapped on the mid-Norwegian margin in Batchelor et al. (Nature, 2023). The ridges were mapped in ESRI ArcMap, using bathymetric data collected by the Norwegian Mapping Authority and the Norwegian Defence Research Establishment (FFI). They include data acquired through the Norwegian MAREANO seafloor mapping programme (, that are licensed under a Creative Commons Attribution 4.0 International (CC BY 4.0) license. Detailed information about the bathymetric data and mapping methods are outlined in the associated manuscript and README.txt file contained within this dataset.


Software / Usage instructions

Data are presented in ESRI shapefile (.shp) format which can be read by most geographical information systems (e.g. ESRI ArcGIS, QGIS, GMT etc). An accompanying Microsoft Excel file is also provided.
