Lake Baikal in eastern Siberia is a crucial site for detecting long-term global changes, owing to its high sensitivity to climatic oscillation and its extraordinarily long history. Because lacustrine sediments have an advantage in providing high-resolution information, the sediments in Lake Baikal contain excellent continuous records of past conditions including paleoclimates, evolution, and specification of organisms. Based on the study by the Baikal Drilling Project, this book provides information on global climatic and environmental changes for as much as 12 million years. The book also includes discussions of comparatively short-term changes such as glacial and interglacial transitions that directly link to the present and future environment. Long Continental Records from Lake Baikal summarizes the latest knowledge on the paleoenvironment and provides a foundation for further studies in global environmental changes.
