submarine topography

"From New York Times bestselling author Susan Casey, an awe-inspiring portrait of the mysterious world beneath the waves, and the men and women who seek to uncover its secrets For all of human history, the deep ocean has been a source of wonder and terror, an unknown realm that evoked a singular, compelling question: What's down there? Unable to answer this for centuries, people believed the deep was a sinister realm of fiendish creatures and deadly peril. But now, cutting-edge technologies allow scientists and explorers to dive miles beneath the surface, and we are beginning to understand this strange and exotic underworld: A place of soaring mountains, smoldering volcanoes, and valleys 7,000 feet deeper than Everest is high, where tectonic plates collide and separate, and extraordinary life forms operate under different rules. Far from a dark void, the deep is a vibrant realm that's home to pink gelatinous predators and shimmering creatures a hundred feet long and ancient animals with glass skeletons and sharks that live for half a millennium-among countless other marvels. Susan Casey is our premiere chronicler of the aquatic world. For The Underworld she traversed the globe, joining scientists and explorers on dives to the deepest places on the planet, interviewing the marine geologists, marine biologists, and oceanographers who are searching for knowledge in this vast unseen realm. She takes us on a fascinating journey through the history of deep-sea exploration, from the myths and legends of the ancient world to storied shipwrecks we can now reach on the bottom, to the first intrepid bathysphere pilots, to the scientists who are just beginning to understand the mind-blowing complexity and ecological importance of the quadrillions of creatures who live in realms long thought to be devoid of life. Throughout this journey, she learned how vital the deep is to the future of the planet, and how urgent it is that we understand it in a time of increasing threats from climate change, industrial fishing, pollution, and the mining companies that are also exploring its depths. The Underworld is Susan Casey's most beautiful and thrilling book yet, a gorgeous evocation of the natural world and a powerful call to arms.".

Introduces readers to the underwater volcanoes, trenches, and ridges.

A picture book that looks at the work of oceanographic cartographer Marie Tharp.

"Marie Tharp earned a graduate degree in geology in the 1940s, at a time when scientific careers were largely unavailable to women. Marie's vision and tenacity paved the way for her to become one of the greatest oceanographic cartographers of the 20th century. She was the first person to map the ocean floor and discover the 40,000 mile long Mid-Ocean Ridge and Rift Valley. Her astounding discovery supported the theory of continental drift, which led to the theory of plate tectonics. But it was not an easy road, and Marie struggled to receive the credit she deserved for her discovery. From Marie Tharp's early childhood dreams all the way to her defining achievement, Josie James's Marie's Ocean is the story of one of earth science's greatest hidden figures"--From the publisher's web site.

Presents the life of the scientist responsible for the first map of the ocean floor, describing her experiences with sexism and her pioneering work which led to the confirmation of the theory of continental drift.

Before Marie Tharp's groundbreaking work in the 1950s, the ocean floor was a mystery?then, as now, we knew less about the bottom of the sea than we did about outer space. In a time when women were held back by the casually sexist atmosphere of mid-twentieth-century academia?a time when trained geologists and scientists like Tharp were routinely relegated to the role of secretary or assistant?Tharp's work would completely change the world's understanding of our planet's evolution. By transforming dry data into beautifully detailed maps that laid the groundwork for proving the then controversial theory of continental drift, Tharp, along with her lifelong partner in science, Bruce Heezen, upended scientific consensus and ushered in a new era in geology and oceanography.

Marie Tharp always loved maps. Traveling with her father to make surveys, she felt like maps talked to her. Then in college, a teacher pointed out that though the oceans cover more than half the earth's surface, scientists knew very little about the bottom of the seas. She wondered, how deep are the oceans? Is the seafloor flat or are there mountains on the ocean floor?.

Explores, through the use of CGI animation, the terrain and life at the bottom of Earth's oceans.

An examination of the professional and personal life of Marie Tharp, a geologist and oceanographic cartographer who mapped the ocean floor.

Presents an introduction to underwater scientists, including information on what they do, how they get underwater, and an overview of discoveries they have made.
