What lies beneath tons of mud in the cave of FRACHTI.
Dive at 225 meters in the sea area of the Bay Valley of Argolis Gulf, did the participants in the research program TerraSubmersa, in collaboration with Ephorate of Underwater Antiquities of the Swiss School of Archaeology, University of Geneva and the Greek Centre for Marine Research the sea area of the bay valley in the Gulf of Argolis.
Target of marine geological-geophysical survey was to map in detail the seabed sediments and marine area of the eastern Argolis Gulf to come out with a representation of the area at various periods of the past when the sea level was lower than the current up to 120 -125 meters and identify possible elements in bottom-evidence of the presence of prehistoric people in the surrounding area of the cave in the eastern Gulf of Argolis.
The results from the first analysis and interpretation of geological-Marine geophysical data include:
1) the identification of palaeo-coast at various depths (up to 225 meters below the current sea level) and at various periods of the Prehistoric times (20,000 years, 60,000 years, 140,000 years before present).
2) Rich data on the representation of the terrain near the prehistoric cave, including the river bed that flowed near the cave and is now submerged and covered by marine sediment.
3) The existence of an area covered with 2-3 meters of mud at a depth of about 10-12 meters, near the cave entrance, which is likely to contain traces of prehistoric human presence and should be investigated with underwater excavation.
The detailed and systematic mapping and exploration of the sea bed of the East Coast of Argolis, near the cave FRACHTI, took both vessels TURANOR PLANETSOLAR and ALKYON between 11-28 of August.
