Long-range sidescan sonar data, as well as deep-towed high-resolution seismic, 10 and 12 kHz echogram, and core data, have allowed an overview of the various sedimentary processes operating along the length of Flemish Pass. At the southern end of the pass profile data reveal that geostrophic currents are actively eroding the flanks of sediment drifts. Depositional lobes at the foot of slope gullies in the centre of Flemish Pass are characterized by elongate diapiric structures around their margins and may have triggered turbidity currents that spread across the floor of the pass. The northern margin of Flemish Pass shows evidence of (possibly historic) downslope sediment movement.
