Follow the fascinating journey of Captain Nemo and explore the ocean's wonders, both real and imagined ... or are they?

What if a sixteen-year-old assistant traveled aboard the storied Nautilus, the narwhal-shaped submarine of 20,000 Leagues Under the Sea? And what if he were the sole survivor of the ill-fated voyage and went on to relay his adventures to a certain . . . Jules Verne? Find this brave young man's own account in the lavishly illustrated Oceanology, a tale of an 1866 voyage of discovery that investigates diving bells and shipwrecks; coral reefs and ice canyons; sharks, giant octopi, and luminous sea monsters; underwater volcanoes, and even the legendary island of Atlantis.
