Upheaval from the Abyss spans a 130-year period, beginning with the early, backbreaking efforts to map the depths during the age of sail; continuing with improvements in research methods spurred by maritime disaster and war; and culminating in the publication of the first map of the world’s ocean floor in 1977. The author brings this tale to life by weaving through it the personalities of the scientists-explorers who struggled to see the face of the deep, and reveals not only the facts of how the ocean floor was mapped, but also the human dimensions of what the scientists experienced and felt while in the process.
