From the shark-rich waters surrounding Coco Island, Costa Rica, to the iceberg-studded sea off Franz Josef Land, Russia, this incredible photographic collection showcases the thriving marine ecosystems that Sala is working to protect. Offering a rare glimpse into the world's underwater Edens, more than 200 images take you to the frontier of the Pristine Seas expeditions, where Sala's teams explore the breathtaking wildlife and habitats from the depths to the surface--thriving ecosystems with healthy corals and a kaleidoscopic variety of colorful fish and stunning creatures that have been protected from human interference. With this dazzling array of photographs that capture the beauty of the water and the incredible wildlife within it, this book shows us the brilliance of the sea in its natural state."--

It contained a multiple bison kill, a mammoth kill, and possibly a horse kill in a deeply stratified sedimentary context. Scattered across the buried occupation surface with the bones of late Pleistocene animals were several thousand stone tools and waste flakes from their manufacture and repair. Because of the unique occurrence of an algal black mat that buried the Clovis-age surface immediately after abandonment, the distributional integrity of the artifacts and debitage clusters is exceptional for Paleoindian sites. Excavation of the Clovis hunters’ camp 50 to 150 meters south of the kills revealed artifactual evidence typical of hunting camp activity, including hide working and weapons repair. Impact flakes conjoining with Clovis points clearly tied the camp to the bison kill. The unique nature of the site and this comprehensive study of the excavated material constitute one of the most important contributions to our knowledge of Paleoindian hunters in the New World.

DOWNLOAD EBOOK →As political, economic, and environmental issues increasingly spread across the globe, the science of geography is being rediscovered by scientists, policymakers, and educators alike. Geography has been made a core subject in U.S. schools, and scientists from a variety of disciplines are using analytical tools originally developed by geographers. Rediscovering Geography presents a broad overview of geography's renewed importance in a changing world. Through discussions and highlighted case studies, this book illustrates geography's impact on international trade, environmental change, population growth, information infrastructure, the condition of cities, the spread of AIDS, and much more. The committee examines some of the more significant tools for data collection, storage, analysis, and display, with examples of major contributions made by geographers. Rediscovering Geography provides a blueprint for the future of the discipline, recommending how to strengthen its intellectual and institutional foundation and meet the demand for geographic expertise among professionals and the public.
