The aim of this 3-day field trip in the Bay of Mont-Saint-Michel, located between Normandy and Brittany (NW France), is to examine the different sedimentary environments, which compose this hypertidal coastal system (a tide-dominated, wave-influenced embayment, a tide-dominated estuary, a wave-dominated sandy shoreline). Hydrodynamics, sedimentary facies, and sequences, Holocene infill, and evolution will be discussed through field observations, sediment cores, very high resolution seismic, and ground-penetrating radar data. The field trip includes a sightseeing tour of Mont-Saint-Michel and an overview of Norman gastronomy.
