• Resumen

  • Multiple channel features abounding a Pliocene sedimentary prism in the central North Sea has been mapped using 3D seismic data (PGS North Sea Mega-merge). Formation of the channels is related to the combined action of focussed fluid expulsion from fracture zones and lateral dispersal of sediments by bottom currents. The results suggests that the North Sea during the Pliocene and early Pleistocene formed an intermediate-water seaway accommodating meridional ocean currents.
