| Objective | The general objective of the project that this cruise is part of is to study the Quaternary evolution of the Seine bay. It involves understanding how the different morpho-sedimentary units were put in place during the end of the Quaternary and how they have evolved since the beginning of the Holocene high sea-level stand. The final objective is to build a model for this type of sedimentary basin represented by a vast megatidal bay that has specific architecture in a well defined stratigraphic framework, to specify the geometrical relations between the coastal entities and define the role of the morphology and the nature of the underlying geological substrate, including the network of paleovalleys, in the location, shape and evolution of these various entities. These studies were undertaken in the frame of a thesis by F. BenabdelHouahed, cofinanced by the Lower Normandy regional council and BRGM. Following the BaieSeine cruise surveying the entire area in April/May 2007 (see map below), this Seine THR cruise was devoted to seismic exploration of the most coastal zones in the Bay, particularly in the western sector Bay of Veys and its surrounding areas), and in the eastern sector between Ouistreham and Trouville. The cruise was supplemented in late July 2008 by the SeineHR cruise which completed the seismic prospection of the entire study area. The cruise was related to the BRGM Land-Sea Transition research project. |
