Luigi Usai discovery on submerged mediterranean banks:
Birsa Bank, Alfil Bank, Fonkal Bank, Bouri Bank, Madrepore Bank and Gela Basin, Spisse Bank, Estafette Bank, Galite Channel, Galite Plateau, Skerki Channel and many more without name, were fortress surrounded by very big walls. Now it’s all underwater, under the Mediterranean Sea. I suggest to investigate with high resolution bathymetry these places to create a more detailed map to let scientists learn more about those constructions and civilisations.
