The Bay of Biscay (BoB) is a hotspot of internal tide generation where internal solitary waves (ISW) are common phenomena. However, in situ observations of ISWs are relatively scarce off the shelf, and even more over the shelf. Because of the lack of relevant data, and the common use of hydrostatic hydrodynamic models over the BoB, ISWs have been neglected from all sediment dynamic studies in the region. However, ISWs could potentially be strong contributor during the summer time, as evidenced over other shelves worldwide. Therefore, a detailed assessment of the impact of internal tides and ISWs on sediment resuspension is needed to improve our understanding of the sediment dynamics in the BoB. The objective of the SOLIBOB field experiment is to collect for the first-time high frequency sediment dynamics data over the BoB. Two moorings have been deployed over a cross-shore axis (30 and 50 m deep) off Southern Britany in the vicinity of the mid-shelf mud-belt ("Grande Vasière"). Those moorings, recording velocity, turbidity and temperature profiles, would allow to monitor the propagation of ISWs. The moorings have been deployed in summer during the first mission, and recovered 5 to 6 weeks later during the second mission. During the first leg the MVP (Moving Vessel Profiler) has been deployed to collect data along a cross-shore transect.
