Studying Antarctica has never been for the fainthearted."Hereabouts died a very gallant gentleman, Captain L. E. G. Oates of the Inniskilling Dragoons. In March 1912, returning from the Pole, he walked willingly to his death in a blizzard to try to save his comrades, beset by hardship."—Inscription on a cross placed near presumed final resting place of Antarctic explorer Lawrence "Titus" Oates, The Terra Nova Expedition, 1910-1913 "We have one survival bag for every two people."—Antarctic paleontologist William Hammer, Transantarctic Vertebrate Paleontology Project, 2004 "When the ice cracks, it can sound like massive thunder rolls that seem to go on forever. If it is a serious cracking in the ice, it literally sounds like canon shots."—Eighth-grade science teacher and Antarctic diver Robin Ellwood, Lake Ecosystems in Antarctica Project, 2008-2009 Humanity's fascination with the land at the bottom of the globe dates back at least to the ancient Romans, who imagined Terra Australis Incognita—the "unknown southern land"—and drew it on their maps even though no one had ever seen it. It took a thousand years for this unknown land to become known. Despite the many people who have since visited it, conquering the Antarctic frontier is a never-ending challenge that calls scientists and explorers to risk their lives in the pursuit of knowledge. Frozen Secrets is the tale of a continent, the inside story of the critical, cutting-edge research that brave men and women from around the world have done and still do in Antarctica. Sally M. Walker traces expeditions from the earliest explorers to today's research stations, where contemporary scientists work in some of the harshest conditions on Earth. Whether they study the formation of polar ice or the stratigraphy of ancient rock or the fossils of newly discovered dinosaurs or the chemistry of air trapped in miniscule frozen bubbles, the scientists working in Antarctica are building a body of knowledge that will influence future generations as they make choices that could affect the course of the whole planet.

Editorial Reviews

Children's Literature - Amy McMillan
Antarctica has been a source of allure and mystery since the time of Ptolemy, two millennia ago. Walker whets the reader's appetite for more, covering such topics as early and current explorations and methods of scientific study, the various dangers and challenges of the terrain, the science of snow, ice and glaciers, geological history, animal life, and what future discoveries may reveal about the region. The majestic beauty of the land is often juxtaposed with the harsh and deadly realities of the climate. Beginning with the first black-and-white images from 1910 to modern images taken from space, the awesome photographs capture a bit of the wonder of the landscape and what it is like for the explorers and scientists who live and work there. The main text is offset in an icy blue bubble for easy reading while photos, graphs, diagrams, maps and charts accent the text and give additional information. There is an index, glossary, listing of source notes and bibliography and a list of books and websites for further reading. This is a beautiful book, perfect for classrooms or cold-climate enthusiasts. Reviewer: Amy McMillan
Kirkus Reviews
No ice crystal is left unturned in this sweeping historical and scientific examination of Antarctica. It's a relatively new "discovery"; the first person to set foot on the continent was a Briton in 1821. Walker briefly chronicles the ill-fated expeditions of such explorers as Scott and Shackleton, as well as Amundsen's successful trek to the South Pole. Although several nations have been engaged in serious research on the continent for more than 50 years, Antarctica remains a mysterious scientific frontier. The author explains Antarctica's unique place in international diplomacy and collaboration with the signing of the Antarctic Treaty. The text succinctly discusses complex discoveries made in such fields as biology, climatology, geology, oceanography and paleontology and the implications these discoveries have on understanding the planet as a whole. Attention is also given to the difficult, often dangerous conditions under which scientists must live and work. Photographs, maps and other illustrations, many in color, appear on every one of the attractively designed pages. Informative, insightful and engaging, this is an exceptional introduction to our southernmost continent. (glossary, source notes, bibliography, further reading and websites, index) (Nonfiction. 9-14)
School Library Journal
Gr 5�9—All of Walker's impressive writing talents are on display in this book on the frozen continent. The author's clear and lively narrative begins with a brief history of the first explorers, including some grisly deaths, and then describes in detail the work of current researchers. Walker paints a vivid picture of the hardships and special considerations required of those who work in Antarctica. Children will almost shiver as they read the description of the scuba diver's preparations to enter an icy lake. Additionally, the author does a great job of explaining some really complex scientific activities, such as mapping the ground using ice-penetrating radar, so that readers without great knowledge of advanced science can grasp how this work is done. She also shows how Antarctic research can help them understand global climate change and other types of earth-science research. Nearly every page has sharp color photos of the continent and researchers in action or explanatory diagrams. With its superb design and Walker's gripping prose, this book will draw readers in and keep them involved.—Denise Schmidt, San Francisco Public Library
