And while talking about Turkey ---

Remember the Straits broke a very long time ago and a great flood
changed the beach line to be much higher.  The black sea has a wide step
before going down.  Google Earth shows this nicely.

What I'm attempting to say is in time of past, shells in sand and coral
heads were
covered or simply 'put to sea' by the rising water.

It would be interesting to do a similar search for long past cost line
and not look
for buildings and such - those were found - but look further out and see if
something was left.  Likely a deep dredge operation or exploratory dive.

IIRC, Smithsonian sponsored or in part sponsored a search for the old
cities.
They found ships sunk in the harbor with wine in casts and other trade.

Wonder what else might be there, just thought to be 'normal' stuff by the
crew looking for big stuff.
