Bill Cassidy has led meteorite recovery expeditions in the Antarctic for many years. His searches have resulted in the collection of thousands of meteorite specimens from the ice. This fascinating story is a first-hand account of his field experiences on the US Antarctic Search for Meteorites Project, which he carried out as part of an international team of scientists. Cassidy describes this hugely successful field program in Antarctica and its influence on our understanding of the moon, Mars and the asteroid belt. In this 2003 book, he describes the hardships and dangers of fieldwork in a hostile environment, as well as the appreciation he developed for the beauty of the place. In the final chapters he speculates on the results of the trips and the future research they might lead to.

Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.

By tracing the English word permafrost back to its Russian roots, this unique intellectual history uncovers the multiple, contested meanings of permafrost as a scientific idea and environmental phenomenon.

Featuring the previously unpublished diary of José María Sobral, Under-Lieutenant of the Argentine Navy, this book provides insight on his life and his participation in Otto Nordenskjöld's Swedish Antarctic Expedition of 1901-1903. This biography highlights Sobral's personal thoughts on the mission, his position, the science being discovered, and the geopolitical situation around him. The reader also learns about the state of science, Antarctic exploration, and cultural-political-issues at that time. The author's critical and contextual analysis of the diary explains more about Sobral and his role in Argentina, Antarctica, science and history. This paints a detailed picture of Sobral as an individual, and provides the framework to depict the world in which Sobral lived and worked as well as his expedition and accomplishments. The book aims to explain the context of Sobral's writings, the significance of the events he described in his diary entries, and the way all of these events tied into history and scientific discovery.

This timely Research Handbook explores the concept of polar law as a coherent body of law and as a set of rules and principles that applies to both the Arctic and Antarctic. It captures the evolution of polar law and policy, identifying future directions for research in this emerging and growing field.
