| Objective | JERICObent-5 is composed of two LEGs, on R/V Thalia and R/V 'Côtes de la Manche' respectively, which aim to realize a synoptic map of the extension of the West Gironde Mud Patch (WGMP) with a reliability and a resolution better than the one obtained until now. In fact, our first research cruise (JERICObent-1, Oct.-Nov. 2016) clearly indicated that the mapping recently proposed by Cirac et al (2016) was more representative of the maximum expansion of WGMP over the last 35 years recent years rather than its current surface. The first LEG on the R/V Thalia aims to obtain a "medium-resolution" mapping by coupling acoustic mapping methods and geophysical methods of THRseismic reflection with a chirp "Peskavel". The acoustic and geophysical data thus acquired are calibrated by sedimentology data collected during the second LEG on the R/V 'Côtes de la Manche'. This work is part of the EU JERICO-NEXT project (2015-2018) and the joint project LEFE (2018-2020) and DRIL-EC2CO (2018-2019).
