From sandy beaches to mysterious, inky depths, this beautiful book is the story of ocean exploration, from shore to ocean floor. Seen from space, Earth is a swirl of blue and white. The blue is Earth's oceans, which cover 70 percent of its surface. Yet the ocean is the most unexplored region of our planet. From Shore to Ocean Floor is the story of how humans went from building the first boats to discovering the secrets of the deep. Marvel at incredible scientific discoveries, be dazzled by some of the most exciting new species, and admire the incredible people who took the very first steps below the surface.
Dive into the world of Alvin the Submersible, as award winning journalist Aly Brown shares the stories of what lies beneath the waves, including lost hydrogen bombs, underwater volcanoes, storied shipwrecks, and hundreds of new species. Humans have explored the far reaches of the globe, from the top of Mount Everest to Badwater Basin—a stretch of land 282 feet below sea level. But for most of our time on this planet, the ocean has been a huge mystery. It's only in the last 50 years that scientists have really started studying the ocean floor, with the help of one amazing creation: Alvin the submersible. A deep-sea vessel that can sink miles below the surface with three people inside, Alvin and its crew have uncovered a treasure trove of information in the last fifty years. From tracking down lost hydrogen bombs to exploring underwater volcanoes to capturing footage of storied shipwrecks, there's so much waiting to be discovered beneath the waves! Join award winning journalist Aly Brown as she dives into the wonders of Alvin’s world and see for yourself what lies in the last unexplored place on earth!
Explores methods and devices scientists use to explore the seafloor, focusing on their history, current developments, and potential for future discoveries. Clear text, vibrant photos, and helpful infographics make this book an accessible and engaging read. Plus, two "Scientist Bio" features highlight people who helped make this amazing technology possible.
The riveting story of the exploration of the final frontier of our planet—the deep ocean—and history-making mission to reach the bottom of all five seas. Humankind has explored every continent on earth, climbed its tallest mountains, and gone into space. But the largest areas of our planet remain largely a mystery: the deep oceans. At over 36,000 feet deep, there areas closest to earth’s core have remained nearly impossible to reach—until now. Technological innovations, engineering breakthroughs and the derring-do of a team of explorers, led by explorer Victor Vescovo, brought together an audacious global quest to dive to the deepest points of all five oceans for the first time in history. The expedition pushed technology to the limits, mapped hidden landscapes, discover previously unknown life forms and began to piece together how life in the deep oceans effects our planet—but it was far from easy. Expedition Deep Ocean is the inside story of this exploration of one of the most unforgiving and mysterious places on our planet, including the site of the Titanic wreck and the little-understood Hadal Zone. Vescovo and his team would design the most advanced deep-diving submersible ever built, where the pressure on the sub is 8 tons per square inch—the equivalent of having 292 fueled and fully loaded 747s stacked on top of it. And then there were hurricane-laden ocean waters and the byzantine web of global oceanography politics. Expedition Deep Ocean reveals the marvelous and other-worldly life found in all five deep ocean trenches, including several new species that have posed as of yet unanswered questions about survival and migration from ocean to ocean. Then there are the newly discovered sea mounts that cause tsunamis when they are broken by shifting subduction plates and jammed back into the earth crust, something that can now be studied to predict future disasters. Filled with high drama, adventure and the thrill of discovery, Expedition Deep Ocean celebrates courage and ingenuity and reveals the majesty and meaning of the deep ocean.
Her maps of the ocean floor have been called "one of the most remarkable achievements in modern cartography", yet no one knows her name. Soundings is the story of the enigmatic, unknown woman behind one of the greatest achievements of the 20th century. Before Marie Tharp, geologist and gifted draftsperson, the whole world, including most of the scientific community, thought the ocean floor was a vast expanse of nothingness. In 1948, at age 28, Marie walked into the newly formed geophysical lab at Columbia University and practically demanded a job. The scientists at the lab were all male; the women who worked there were relegated to secretary or assistant. Through sheer willpower and obstinacy, Marie was given the job of interpreting the soundings (records of sonar pings measuring the ocean's depths) brought back from the ocean-going expeditions of her male colleagues. The marriage of artistry and science behind her analysis of this dry data gave birth to a major work: the first comprehensive map of the ocean floor, which laid the groundwork for proving the then-controversial theory of continental drift. When combined, Marie's scientific knowledge, her eye for detail and her skill as an artist revealed not a vast empty plane, but an entire world of mountains and volcanoes, ridges and rifts, and a gateway to the past that allowed scientists the means to imagine how the continents and the oceans had been created over time. Just as Marie dedicated more than twenty years of her professional life to what became the Lamont Geological Observatory, engaged in the task of mapping every ocean on Earth, she dedicated her personal life to her great friendship with her co-worker, Bruce Heezen. Partners in work and in many ways, partners in life, Marie and Bruce were devoted to one another as they rose to greater and greater prominence in the scientific community, only to be envied and finally dismissed by their beloved institute. They went on together, refining and perfecting their work and contributing not only to humanity's vision of the ocean floor, but to the way subsequent generations would view the Earth as a whole. With an imagination as intuitive as Marie's, brilliant young writer Hali Felt brings to vivid life the story of the pioneering scientist whose work became the basis for the work of others scientists for generations to come.
'Deep-Sea Sediments' focuses on the sedimentary processes operating within the various modern and ancient deep-sea environments. The chapters track the way of sedimentary particles from continental erosion or production in the marine realm, to transport into the deep sea, to final deposition on the sea floor.
Practice measurement while learning about marine ecology and life in the ocean layers! There are so many animals living in the vast oceans of our planet! Not only does this title teach readers how to measure marine life by grams, feet, inches, and other similar units of measurement, but it teaches them how to measure ocean water using Celsius and Fahrenheit. Using familiar and unfamiliar units of measurement in an unfamiliar territory challenges readers to expand their measurement and STEM skills. Exciting images, simple practice problems, easy-to-read text, clear mathematical charts and diagrams, and an accessible glossary all help children advance their mathematical skills.
