Sands on continental margins

Investigation of sand-dominated margin systems as analogues for hydrocarbon reservoirs is one of the major tasks of TTR. Several sand-rich deep-sea fan systems in the Western Mediterranean have been mapped and cored. In many places on the North Atlantic continental margin significant accumulations of sand deposited by strong bottom currents have been discovered and investigated. Integration of acoustic seafloor mapping with ground truthing by bottom sampling and video observations helps to understand geometry and distribution of sand bodies in such sedimentary systems.
