  abstract = {{E}vidences of sedimentation affected by oceanic circulation, such as nepheloid layers and contourites are often observed along continental slopes. {H}owever, the oceanographic processes controlling sedimentation along continental margins remain poorly understood. {M}ultibeam bathymetry and high-resolution seismic reflection data revealed a contourite depositional system in the {M}ozambican upper continental slope composed of a contourite terrace (a surface with a gentle seaward slope dominated by erosion) and a plastered drift (a convex-shape sedimentary deposit). {A} continuous alongslope channel and a field of sand dunes (mainly migrating upslope), formed during {H}olocene, were identified in the contourite terrace at the present seafloor. {S}eismic reflection data of the water column show internal waves and boluses propagating in the pycnocline near the upper slope. {T}he channel and the dunes are probably the result of the interaction of the observed internal waves with the seafloor under two different conditions. {T}he alongslope channel is located in a zone where intense barotropic tidal currents may arrest internal solitary waves, generating a hydraulic jump and focused erosion. {H}owever, upslope migrating dunes may be formed by bottom currents induced by internal solitary waves of elevation propagating landwards in the pycnocline. {T}hese small-scale sedimentary features generated by internal waves are superimposed on large-scale contouritic deposits, such as plastered drifts and contourite terraces, which are related to geostrophic currents. {T}hese findings provide new insights into the oceanographic processes that control sedimentation along continental margins that will help interpretation of palaeoceanographic conditions from the sedimentary record.},
