A field campaign was cerned out in the continental shelf near the District of Santa Marta; five - 10kHz StrataBoxT" subbottom profiles taken in Taganga, Santa Marta and Gaira Bays, allowed penetration into the sea bed of approximately 30 m, due to the fact that the seafloor was constituted mostly of fine sands, lack of suspended sediment and relative shallow depths. These profiles showed the submarine relief derived from the spurs of the Sierra Nevada of Santa Marta (SNSM) in the continental shelf; because of its sharp features, common characteristics of the continental shelf such as low slope and homogeneity only appeared in some sections and the accumulation of sediments showed by the reflectors in the obtained records, were given principally in the depressions between topographic high places and, in some sectors, where the slope is lower than 2°. Topographic anomalies of the shelf seem to be inherited from a former coast line, controlled by structures in NNW direction that define the axes of the current bays, and for a megastructure possibly associated with Oca and Santa Marta fault systems, with en important role in the raising and evolution of the SNSM and the associate basins.Downloads
