Short summary
A large quantity a continental material is transported to the oceans by the world rivers. Once in the ocean, these particles can be transported down the continental shelf thanks to underwater avalanches. The repetition of such massive events can form very important sedimentary deposits at the continent–ocean transition. Data obtained during an oceanic cruise in 2010 allowed us to study such a system located offshore of Gabon and to evaluate the importance sediment transport in this area.
