| Abstract |
Orientated photographs of the sea-bed, together with grab and short-core sediment samples, at 18 stations in the Strait of Gibraltar region confirm the presence in the Strait of powerful and persistent westward-directed bottom currents. Sedimentary structures and textures provide data on the direction and strength of this bottom flow which are consistent with existing hydrologic observations of the Mediterranean undercurrent. Two major depressions (Gibraltar canyon and Ceuta canyon) traverse the eastern end of the Strait and are characterised by more tranquil sedimentation and spasmodic down-canyon transport of sediment. |
