Searching for Atlantis — Sunken Cities and Ancient Cataclysms
Ancient texts, sophisticated megalithic structures, and legends from around the world tell of grand civilizations that once thrived on the planet that suddenly disappeared without warning from great catastrophes that occurred long ago. What did Plato mean by the location of Atlantis being west of the Pillars of Hercules? Could it have actually been in the Caribbean Ocean all along? From studying ice core samples and historic bathymetric charts, to exciting new underwater discoveries that have been made in the western Atlantic Ocean, Sam Tripoli and I dig deep to find evidence that finally points to the location of the famous sunken city of Atlantis.
Bathymetry (/bəˈθɪmətri/; from Ancient Greek βαθύς (bathus) ‘deep’, and μέτρον (metron) ‘measure’) is the study of underwater depth of ocean floors or lake floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. Bathymetric (or hydrographic) charts are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called depth contours or isobaths) and selected depths (soundings), and typically also provide surface navigational information. Bathymetric maps (a more general term where navigational safety is not a concern) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed. The global bathymetry is sometimes combined with topography data to yield a global relief model. Paleobathymetry is the study of past underwater depths. (Wilkipedia)
