The archaeological deposit of Biéroc at La Mondrée is currently the only known submerged Middle Paleolithic habitat in Europe (approximately -20 m) which is remarkably well preserved, giving this site international reputation and heritage value.

Till now, investigations carried out had been found insufficient to properly characterize the deposit; in particular with regard to:

  1. its integration within the territory of Neanderthal hunter-gatherers. Better characterization of the configuration of La Mondrée cove during its occupation(s) in the Middle Paleolithic (valley morphology and shape, type and thickness of sediments infilling the valley, location of settlement with respect to stream) is thus needed. We manage to reconstruct paleo-landscapes using the sub-bottom profiler data by mapping seismic reflectors (top of substratum and sedimentary units related to last interglacial) ;
  2. the caracterisation of the levels of habitat (the foot of the cliff and the scree), analysing the morphology, the nature and thickness of the associated sediments (interferometric sonar, backscatter and bathymetry) ;
  3. the structural and contextual components of the site by mapping the granite rock bar of Biéroc and the cove of La Mondrée.

The very high resolution data collected will also help to prepare a coring campaign that would aim at identifying the succession of occupation levels of the archaelogical deposit.
