In December 1872, HMS Challenger embarked on the first round-the-world oceanographic expedition. Its goal: to shine a light on the mysteries of the deep sea. For the next four years, Challenger's naturalists explored the oceans, encountering never-before-seen marvels of marine life. The expedition’s achievements are the stuff of legend. It identified major ocean currents and defining features of the seafloor. It measured worldwide sea temperatures and chemistry. And, most spectacularly of all, it collected nearly five thousand sea creatures and plants new to science.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

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.

Around 13,000 years ago, three things happened at once: (1) Global temperature suddenly stopped rising and plunged back to ice age-frigidity. (2) The Western Hemisphere’s largest mammals, including the horse, camel, woolly mammoth, saber-toothed cat, and dozens more, went extinct. And (3) the uniquely beautiful stonework of the early American Clovis people disappeared from the archeological record. For the past half-century, scientists have struggled to explain the three events. Were they independent of each other, or could they have had a common cause?

Nick Bullock is a climber who lives in a small, green van, flitting between Llanberis, Wales, and Chamonix in the French Alps. Tides, Nick’s second work, is the much-anticipated follow-up to his critically acclaimed debut, Echoes. Tides is a gripping memoir that captures the very essence of what it means to dedicate one’s life to climbing.
