Marennes-Oléron Bay, France
Billeaud, I., Chaumillon, E. and Weber, O. 2005. Evidence of a major environmental change recorded in a macrotidal bay (Marennes-Oléron Bay, France) by correlation between VHR seismic profiles and cores. Geo-Marine Letters 25: 1-10.

Very high resolution seismic profiles were combined with sediment core data from Marennes-Oléron Bay, France (~45.95°N, 1.20°E), in an investigation of major environmental change over the past few thousand years. The results indicated the presence of a major change in the amount and nature of sediment supplied to the bay, where fine-grained material increased during the Medieval Warm Period (AD 950-1450), which phenomenon, in the thinking of the authors, resulted from a combination of human activities (deforestation, farming, land reclamation) and climatic variations.
