Mapping of areas affected by undefined landslides at the present-day seafloor on the eastern lower continental slope of the Cantabrian continental margin (Bay of Biscay)

For the mapping of the canyon features a database with over 1500 km of 2D multi- and single-channel seismic lines, with different degrees of resolution (from a few metres to metric) together with high-resolution multi-beam bathymetry has been analysed and interpreted. Multi-channel seismic records were downloaded from the Archivo Técnico de Hidrocarburos ( https:// geoportal.minetur.gob.es/ATHv2/welcome.do). Single-channel records were mostly obtained with airgun systems (140 to 530 c.i.) and are included in the database from the Instituto de Ciencias del Mar, ICM-CSIC, http://www.icm.csic.es/geo/gma/SurveyMaps. Several multi-beam bathymetry datasets obtained with Simrad EM12 and Atlas HYDROSWEEP DS multibeam echosounders were also compiled and integrated for the present study from the MARCONI, CONTOURIBER, MOWER and BARACA projects, the Fishing General Secretary (Spanish Government) and the EMODnet bathymetry. These data were gridded to a resolution of 200, 100 and 50 m.

    Statement

    The mapping of the landslide area has been carried out based on 2D multi- and single-channel seismic lines, with different degrees of resolution (from a few metres to metric) together with high-resolution multi-beam bathymetry. Multibeam bathymetry recorded using Simrad EM12 and Atlas HYDROSWEEP DS multibeam echosounders, during cruises from the Spanish Fishing General Secretary (2003 and 2004) and several multi-beam bathymetry datasets obtained with Simrad EM12 and Atlas HYDROSWEEP DS multibeam echosounders were also compiled and integrated for the present study from from the MARCONI, CONTOURIBER, MOWER and BARACA projects, the Fishing General Secretary (Spanish Government) and the EMODnet bathymetry. These data were gridded to a resolution of 200, 100 and 50 m.

    Morphometric attributes such as slope gradients, profile curvatures, planar curvatures and roughness were obtained by ArcMap (GIS), and topographic profiles allowed us to obtain a better characterization of area affected by mass wasting landslides.
