In the late 1970s, while working at Marineland in California, Alexandra pioneered the recording of orca sounds by dropping a hydrophone into the tank of two killer whales. She recorded the varied language of mating, childbirth, and even grief after the birth of a stillborn calf. At the same time she made the startling observation that the whales were inventing wonderful synchronized movements, a behavior that was soon recognized as a defining characteristic of orca society. In 1984, Alexandra moved to a remote bay in British Columbia to continue her research with wild orcas. Her recordings of the whales have led her to a deeper understanding of the mystery of whale echolocation, the vocal communication that enables the mammals to find their way in the dark sea. A fascinating study of the profound communion between humans and whales, this book will open your eyes anew to the wonders of the natural world.

    Readers take an extraordinary trip, starting in the 1600s with an alchemist's air conditioning of Westminster Abbey and scientists' creation of thermometers. Later, while entrepreneurs sold Walden Pond ice to tropical countries -- packed in "high-tech" sawdust -- researchers pursued absolute zero and interpreted their work as romantically as did adventurers to remote regions. Today, playing with ultracold temperatures is one of the hottest frontiers in physics, with scientists creating useful particles Einstein only dreamed of. Tom Shachtman shares a great scientific adventure story and its characters' rich lives in a book that has won a grant from the prestigious Alfred P. Sloan Foundation. Absolute Zero is for everyone who loves history and science history stories, who's eager to explore Nobel Prize-winning physics today, or who has ever sighed with pleasure on encountering air conditioning.

    But as a member of the most endangered marine mammal species in U.S. waters, Kauai Pup 2, or KP2, is too precious to lose, and he embarks on an odyssey that will take him across an ocean to the only qualified caretaker to accept the job, eminent wildlife biologist Dr. Terrie M. Williams.The local islanders see KP2 as an honored member of their community, but government agents and scientists must consider the important role he could play in gathering knowledge and data about this critically endangered and rare species. Only 1,100 Hawaiian monk seals survive in the wild; if their decline continues without intervention, they face certain extinction within fifty years. In a controversial decision, environmental officials send KP2 to Williams's marine mammal lab in Santa Cruz, California, where she and her team monitor his failing eyesight and gather crucial data that could help save KP2's species.But while this young seal is the subject of a complex environmental struggle and intense media scrutiny, KP2 is also a boisterous and affectionate animal who changes the lives of the humans who know and care for him-especially that of Williams. Even as she unravels the secret biology of monk seals by studying his behavior and training him, Williams finds a kindred spirit in his loving nature and resilient strength. Their story captures the universal bond between humans and animals and emphasizes the ways we help and rely upon one another. The health of the world's oceans and the survival of people and creatures alike depend on this ancient connection.The Odyssey of KP2 is an inside look at the life of a scientist and the role that her research plays in the development of conservation efforts, bringing our contemporary environmental landscape to life. It is also the heartwarming portrait of a Hawaiian monk seal whose unforgettable personality never falters, even as his fate hangs in the balance.
