University of California Press Frozen Earth: The Once and Future Story of Ice Ages
In this engrossing and accessible book, Doug Macdougall explores the causes and effects of ice ages that have gripped our planet throughout its history, from the earliest known glaciation - nearly three billion years ago - to the present. Following the development of scientific ideas about these dramatic events, Macdougall traces the lives of many of the brilliant and intriguing characters who have contributed to the evolving understanding of how ice ages come about. As it explains how the great Pleistocene Ice Age has shaped the earth's landscape and influenced the course of human evolution, "Frozen Earth" also provides a fascinating look at how science is done, how the excitement of discovery drives scientists to explore and investigate, and how timing and chance play a part in the acceptance of new scientific ideas. Macdougall describes the awesome power of cataclysmic floods that marked the melting of the glaciers of the Pleistocene Ice Age. He probes the chilling evidence for "Snowball Earth," an episode far back in the earth's past that may have seen our planet encased in ice from pole to pole. He discusses the accumulating evidence from deep-sea sediment cores, as well as ice cores from Greenland and the Antarctic, that suggests fast-changing ice age climates may have directly impacted the evolution of our species and the course of human migration and civilization. "Frozen Earth" also chronicles how the concept of the ice age has gripped the imagination of scientists for almost two centuries. It offers an absorbing consideration of how current studies of Pleistocene climate may help us understand earth's future climate changes, including the question of when the next glacial interval will occur.

Yale University Press Endless Novelties of Extraordinary Interest: The Voyage of H.M.S. Challenger and the Birth of Modern Oceanography
A gripping tale of exploration aboard H.M.S. Challenger, an expedition that laid the foundations for modern oceanography From late 1872 to 1876, H.M.S. Challenger explored the world’s oceans. Conducting deep sea soundings, dredging the ocean floor, recording temperatures, observing weather, and collecting biological samples, the expedition laid the foundations for modern oceanography. Following the ship’s naturalists and their discoveries, earth scientist Doug Macdougall engagingly tells a story of Victorian-era adventure and ties these early explorations to the growth of modern scientific fields. In this lively story of discovery, hardship, and humor, Macdougall examines the work of the expedition’s scientists, especially the naturalist Henry Moseley, who rigorously categorized the flora and fauna of the islands the ship visited, and the legacy of John Murray, considered the father of modern oceanography. Macdougall explores not just the expedition itself but also the iconic place that H.M.S. Challenger has achieved in the annals of ocean exploration and science.
