These features have been described all along the Mediterranean for the last 30 years and interpreted as either soft sediment deformation and incipient landsliding, and more recently, as sediment transport structures. We perform a review and detailed analysis of these undulated sediment features using ultrahigh-resolution seismic and bathymetric data as well as geotechnical information and hydrodynamic time series and hydrographic transects. In this study we show that the characteristics of the sediment undulations (configuration of the reflections down section and between adjacent undulations and overall morphologic characteristics) are incompatible with a genesis by sediment deformation alone and do not show evidence of sediment deformation in most cases. Various processes in the benthic boundary layer can be invoked to explain the variety of features observed in the numerous areas displaying sediment undulationsThis manuscript is a contribution to project E-MARSHAL (IGCP-585) funded by IUGS and UNESCO. The data on the Iberian prodeltas was acquired in the frame of the Spanish project PRODELTA (REN2002-02323). Data for some areas of the continental shelf (Fluvia`-Muga and Ter prodeltas) were acquired by ‘‘Secretaría General del Mar’’ of the Ministerio de Medio Ambiente, y Medio Rural y Marino’’ and provided free of charge. For the Algerian data we thank captain and crew of R/V L’Atalante (campagne PRISME 2007) and funding from French ANR projects ISIS and DANACOR. Borehole geotechnical data was acquired in the frame EC funded project PROMESS-1 (EVR1-CT-2002-40024). Hydrodynamic transects and instrumented moorings were funded by the Office of Naval Research, NICOP Grant N00014-02-1-0252. The ‘‘Generalitat de Catalunya’’ is acknowledged for support through an excellence research group grant (2009-SGR-146).
