the Deepest Place on Earth: A Journey into Mysterious World of Oceans: 4

Beneath the ocean's glittering surface lies the largest and least explored living environment on Earth. Begin in bright, sunlit waters filled with microscopic plankton, coral reefs, powerful sharks and enormous whales. Then descend through the twilight zone, where lanternfish glow and countless animals rise towards the surface each night. Travel deeper into permanent darkness, past creatures that create their own light, across the vast abyssal plains and towards hydrothermal vents where life is powered by chemicals rising from within Earth. Finally, enter the deepest ocean trenches, where delicate animals survive almost eleven kilometres below the waves under pressure more than a thousand times greater than at sea level. Along the way, discover how waves, tides and great currents move the ocean; why seawater is salty; how whales dive and communicate; how coral reefs are built; and how submersibles, robots, sonar and deep-sea landers allow scientists to explore places humans cannot reach alone. Serious, vivid and filled with remarkable real-world science, The Deepest Place on Earth reveals an ocean far more connected, dynamic and alive than it appears from the shore. It also explores the challenges facing marine ecosystems and explains why understanding the ocean is essential to protecting the future of our living planet.
