Where should we search for the remains of a lost ancient civilisation?
We all know about the reports of potentially misdated megalithic buildings around the world, in many cases claimed to be much older than the official timeline says.
But if there really was an ancient global mother civilisation, where is it to be found? Some of us are quite sure about the answer to that question. About 400 feet underwater.
It has been scientifically proven that a water rise of approximately 400 feet occurred at the end of the Pleistocene (the Ice age). But why should we start looking for sunken cities at this depth?
Well, look at the population structures we have today. Where are the major cities in our civilisation? At river mouths and near coastal areas.
The three step illustration shows the fate of an hypothetical harbour town, and how it "sunk" into the sea.
Step one is from the end of the Ice age, at 12,900 BP. It shows the living town, located in the ice free region of the planet. This was before the cataclysmic event took place, which would melt massive amounts of ice and cause the sea to rise.
Step two shows the town after two and a half millennia under water. Only stone foundations are remaining. Sand and silt from the river are flushed out into the sea.
Step three shows the present day underwater landscape. After more than twelve thousand years, sedimentary particles have covered the foundations of the old buildings. Plant growth and coral reefs are probably covering many of the structures. Only a vague geometrical structure remains of the town, visible on the seafloor.
The problem with finding these "hypothetical" cities is that not many are looking for them. Existing marine archaeological research tends to mainly focus on shipwrecks and structures found in shallow water.
It's hard to get a clear view of the underwater landscape at larger depths. Even with excellent diving conditions, it's difficult to get a full view of the layout of the sea bed, and any structures buried there.
The public awareness of underwater structures is changing. People are getting access to resources and information. Google Earth and other satellite image sources are showing sea bed maps.
Side scan sonar and other sensor technologies are being developed, and are getting better and cheaper. Scientists and private researchers, potentially have access to equipment that can penetrate sedimental coverage, and provide a richer view of the seafloor.
If there are sunken cities down there, we will probably see results soon. While funded expeditions may not happen on a large scale, private researchers and enthusiasts can make a difference in the near future.
When the price range for equipment drops, people who have a strong desire to know, can embark on a remarkable adventure in sunken city exploration.
The search goes on.
