Discover the world's ocean—from tides and currents to the creatures living in it to the impact it has on our lives, whether we know it or not—in this overview of the life force that defines and sustains our planet, written by world-renowned oceanographer Sylvia Earle.

Everything you want to know about the ocean can be found inside these minutes. National Geographic Ocean unveils the power and significance of our planet's watery essence: the fundamental importance of the ocean in shaping Earth's climate and chemistry, as well as its vital role in supporting a multitude of life-forms, including our own human race.

World-renowned oceanographer and National Geographic Explorer in Residence Sylvia Earle—affectionately called "Her Deepness"—guides listeners with her lyrical style and inspiring wisdom, describing the evolution, beauty, and impact of our ocean; the challenges it faces, such as climate change, plastic, and overfishing; and the myriad ways we can help protect it.

This engaging story of the ocean celebrates dozens of ocean champions and visionaries, explores the ocean's origin and the nature of water, and features a gallery of wondrous creatures that illustrate the spectacular diversity of life in the sea, from sponges, kelp, and zooplankton to whales, sharks, and sea turtles.

For seaside dwellers and landlubbers alike, this is a book you will turn to again and again to understand why, as Sylvia Earle says, "Everyone, everywhere is inextricably connected to and utterly dependent upon the existence of the sea."
