Embark on an extraordinary journey into the depths of the ocean.Oceanographer Dawn Wright made history in 2022 when she became the first Black person to visit Challenger Deep, the deepest and most unexplored place on Earth—a trip that took her over 10,000 meters beneath the Pacific Ocean’s surface. Remarkably, we know less about the ocean floor than we do about the surface of the moon. Barely one-fifth of the seabed has been mapped in high resolution to date. As an ocean scientist and explorer, Dawn has made it her mission to change that.Mapping the Deep takes you on an extraordinary adventure with an extraordinary woman into the depths of Challenger Deep, showcasing the perseverance and innovation needed for ocean exploration. With a focus on Dawn’s historic dive, her personal journey, and the cutting-edge technology that made the expedition possible, this book highlights the crucial importance of mapping the ocean and its profound impact on our planet’s future. From the fascinating history of the area and the incredible stories of its explorers to the diverse marine life that resides within, prepare to be inspired.Through a blend of history, fascinating facts, and beautiful images, Mapping the Deep offers a unique perspective on the challenges and triumphs of deep-sea exploration.Dr. Dawn Wright, chief scientist of Esri, is a specialist in marine geology, geography, and oceanography. To many, she is @deepseadawn—a name earned after completing numerous trips to the bottom of the ocean. In 1991 she became the first Black woman to dive to the ocean floor in Alvin, a deep-sea submersible vehicle.

"When Dawn Wright submitted her master’s thesis in the 1980s, her supervisor told her that she had no future in oceanography. Today, she is a distinguished oceanographer and chief scientist at software company Esri. In 2022, she became the first Black person to visit Challenger Deep, the deepest place on Earth’s sea bed, more than 10,000 metres below the sea surface. This charming book, written by Wright in collaboration with four Esri Press colleagues, shows how, in her words, “we can turn the unknown deep into the known deep”."
