"The world's oceans cover just over 70.8 per cent of the Earth's surface, and yet we know more about the moon then what lies beneath these dark waters. As early as 5000 BC, efforts have been made to map these oceans, establish trade routes and discover new lands. In more recent years, this energy has focused downwards, into the ocean's inky depths and shadowy seabeds. Award winning writer Carolyn Fry explores all of the above, narrating centuries of maritime exploration - from James Cook to James Cameron - and the fascinating discoveries have helped to map the world."--Publisher.
