| Objective | Vibro-coring and rock-corer samples taken in the Bay of Seine in order to calibrate the seismic data acquired since 2007. The general objective of the overarching project for the Carobseine cruise is to study the Cenozoic evolution in the Bay of Seine. The final aim is to build a precise architecture model for this sort of basin in a clearly defined stratigraphic framework, to specify the geometric relationships between the Cenozoic entities (paleovalleys, coastal prisms)and to define the role played by the morphology and the type of underlying geological substrate in the location, shape and evolution of these different entities. These studies were carried out in the context of a PhD thesis by Massinissa Benabdelhouahed (University of Caen) co-financed by the Lower Normandy regional council and BRGM. The Carobseine mission was the follow up to three seismic prospecting missions conducted in 2007 and 2008 (BaieSeine07 - see Figure 1, Seine THR and Seine HR). Its two main objectives were to take vibro-core samples in recent (Holocene) shore deposits surveyed by VHR seismics and rock-core samples to specify the stratigraphy of the substratum bed surveyed using HR seismics. The cruise is part of the BRGM land-sea transition research project. |
