Excellent thread - well written, put together, researched. Old style ATS. S&F&
...I have long thought that many older / ancient maps might not be inaccurate but rather, document real earth changes - and that major earth changes occur more quickly and frequently than is commonly acknowledged. And your thread seems to go a long way towards proving that speculation. ...Is this what you're suggesting?

The only question I have is on the side by side comparison with Schoner's Antarctica on the left Hadji Ahmed's Antarctica on the right, your caption states "The actual Unfortunate Islands depicted more accurately on the Hadji Ahmed map." I was under the assumption, based on your text, that Schoner's map was actually a more accurate portrayal of the Unfortunate Islands. Is the Ahmed map more accurate?
But locating an undersea continent in the middle of the Atlantic is a bit problematic. Research aided by technological advancements throughout the 20th century has allowed us to chart highly detailed maps of the Atlantic seafloor. What we have found is a pattern of uninterrupted seafloor crustal spreading extending away from a central longitudinal expansion ridge, the Mid-Atlantic Ridge (Fig. 4). There are no excessively large sunken plateaus or evidence of a submerged or subducting continent anywhere in the Atlantic, only a few relatively small plateaus associated with undersea ridges and a few small islands including the Azores that originated from ruptures in the oceanic crust. And in fact there are absolutely no signs of large sunken continents lying beneath any of the world's oceans.
