dc.description.abstractMultibeam bathymetry, high resolution multi-channel, and very high resolution single-channel (3.5 kHz) seismic records were used to depict the complex geomorphology that defines the Galicia Bank region (Atlantic, NW Iberian Peninsula). This region (≈620–5,000 m water depth) is characterized by a great variety of features: structural features (scarps, highs, valleys, fold bulges), fluid dynamics-related features (structural undulations and collapse craters), mass-movement features (gullies, channels, mass-flow deposits, slope-lobe complexes, and mass-transport deposits), bottom-current features (moats, furrows, abraded surface, sediment waves, and drifts), (hemi)pelagic features, mixed features (abraded surfaces associated to mixed sediments) and bioconstructions. These features represent architectural elements of four sedimentary systems: slope apron, contouritic, current-controlled (hemi)pelagic, and (hemi)pelagic. These systems are a reflection of different sedimentary processes: downslope (mass transport, mass flows, turbidity flows), alongslope (bottom currents of Mediterranean Outflow Water, Labrador Sea Water, North Atlantic Deep Water, and Lower Deep Water), vertical settling, and the interplay between them. The architectural and sediment dynamic complexities, for their part, are conditioned by the morphostructural complexity of the region, whose structures (exposed scarps and highs) favor multiple submarine sediment sources, affect the type and evolution of the mass-movement processes, and interact with different water masses. This region and similar sedimentary environments far from the continental sediment sources, as seamounts, are ideal zones for carrying out submarine source-to-sink studies, and can represent areas subject to hazards, both geologic and oceanographic in origines_ES
dc.description.sponsorshipThe research was supported by the Projects ERGAP (Ref. VEM 2003-20093-CO3), CONTOURIBER (Ref. CTM2008-06399-MAR), and MONTERA (CTM-14157-C02), of the Spanish Science and Innovation Ministry. We thank the crew of RV L’Atalante for their help collecting the data, the Instituto Español de Oceanografía (IEO) for providing ZEEE multibeam data, and the cartographer S. García from UTM-CSIC for processing the ERGAP and ZEEE multibeam data. The ‘‘Grupo de Márgenes Continentales’’ (GMC) also thanks the Generalitat de Catalunya for providing economic support in the framework of SGR-2009 (Exp. 00707). Likewise, we thank Seismic Micro-Technology, Inc. for supporting us with the Kingdom Suite Program. F. J. Hernández-Molina is thanked for helpful discussions. This paper has benefited from reviews by an anonymous reviewer and F. J. Hernández-Molinaes_ES
