The Russians' Findings

Zhirov was a chemist by trade and a leading Soviet Atlantologist. The book was written between 1959-63. New data was added for this English edition. Seismics, gravimetrics, climatology, paleobotanical data, geomorphology, plate tectonics, turbidity data, bottom current patterns, submarine erosion and geological data separate this book from most of the rest of the Atlantology field. Cites 825 separate sources in 34 pages of references - Russian, Ukrainian, Greek, German, English, Latin...

Make that nearly fifty years old.  I don't think the science in it will be very up to date. The book says that new data was added, when did Zhirov die anyway?
