Fig. 5 Sediment thicknesses and sedimentation rates were calculated at 12 selected points from
the three long transects (yellow dots and the table). The right chart shows the distribution of the
sedimentation rate from three units

4 Discussion and Conclusions

The development of the Weddell Sea basin witnessed the interplay of complex
sea oor spreading and tectonic processes with the deposition of large amounts of

sediments since the Jurassic. As reported from seismic refraction experiments in
front of the Filchner-Ronne Ice Shelf of the southernmost Weddell Sea, 10 km of
sediments overlie a basement of stretched continental crust (H
