SEAGAS is a 3-year initiative to study processes in the deep sea, involving research groups in Brazil and Europe, including in Germany. The project is being coordinated by PUCRS in collaboration with Géoazur in Nice, France. The hosts have complementary strengths in marine geoscience as applied to submarine gas hydrates, consistent with the...
The Amazon fan contains a gas hydrate province known from a bottom-simulating reflection (BSR) that lies within an upper slope compressional belt. In this study, the extent and character of the BSR and its relation to thrust-fold structures is examined using a grid of 2D and 3D seismic data. We show the BSR to comprise a series of elongate...
Submarine gas hydrate systems are increasingly recognised to be associated with seafloor features recording the venting of gas-rich fluids to the deep ocean. The Amazon deep-sea fan contains a gas hydrate system characterised by a discontinuous bottom simulating reflection (BSR) forming elongate patches that follow the crests of thrust-folds...
