Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.

Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.

“A unique, significant contribution to our maturing studies of the Clovis era.”—Gary Haynes, author of The Early Settlement of North America: The Clovis Era The Paleoindian Clovis culture is known for distinctive stone and bone tools often associated with mammoth and bison remains, dating back some 13,500 years. While the term Clovis is known to every archaeology student, few books have detailed the specifics of Clovis archaeology. This collection of essays investigates caches of Clovis tools, many of which have only recently come to light. These caches are time capsules that allow archaeologists to examine Clovis tools at earlier stages of manufacture than the broken and discarded artifacts typically recovered from other sites. The studies comprising this volume treat methodological and theoretical issues including the recognition of Clovis caches, Clovis lithic technology, mobility, and land use.
