Description
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.
