Available in PDF, EPUB and Kindle. Book excerpt: Thirty-five million years ago, a meteorite three miles wide and moving sixty times faster than a bullet slammed into the sea bed near what is now Chesapeake Bay. The impact, more powerful than the combined explosion of every nuclear bomb on Earth, blasted out a crater fifty miles wide and one mile deep. Shock waves radiated through the Earth for thousands of miles, shaking the foundations of the Appalachians, as gigantic waves and winds of white-hot debris transformed the eastern seaboard into a lifeless wasteland. Chesapeake Invader is the story of this cataclysm, told by the man who discovered it happened. Wylie Poag, a senior scientist with the U.S. Geological Survey, explains when and why the catastrophe occurred, what destruction it caused, how scientists unearthed evidence of the impact, and how the meteorite's effects are felt even today. Poag begins by reviewing how scientists in the decades after World War II uncovered a series of seemingly inexplicable geological features along the Virginia coast. As he worked to interpret one of these puzzling findings in the 1980s in his own field of paleontology, Poag began to suspect that the underlying explanation was the impact of a giant meteorite. He guides us along the path that he and dozens of colleagues subsequently followed as--in true scientific tradition--they combined seemingly outrageous hypotheses, painstaking research, and equal parts good and bad luck as they worked toward the discovery of what turned out to be the largest impact crater in the U.S. We join Poag in the lab, on deep-sea drilling ships, on the road for clues in Virginia, and in heated debates about his findings. He introduces us in clear, accessible language to the science behind meteorite impacts, to life and death on Earth thirty-five million years ago, and to the ways in which the meteorite shaped the Chesapeake Bay area by, for example, determining the Bay's very location and creating the notoriously briny groundwater underneath Virginia. This is a compelling work of geological detective work and a paean to the joys and satisfactions of a life in science. Originally published in 1999.

Download or read book The Chesapeake Bay Crater written by Wylie Poag and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have synthesized 16 years of geological and geophysical studies which document an 85-km-wide impact crater buried 500 m beneath Chesapeake Bay in south eastern Virginia, USA. In doing so, they have integrated extensive seismic reflection profiling and deep core drilling to analyze the structure, morphology, gravimetrics, sedimentology, petrology, geochemistry, and paleontology of this submarine structure. Of special interest are a detailed comparison with other terrestrial and extraterrestrial craters, as well as a conceptual model and computer simulation of the impact. The extensive illustrations encompass more than 150 line drawings and core photographs.
Download or read book The Future Chesapeake written by J. R. Schubel and published by Archway Publishing. This book was released on 2021-05-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chesapeake Bay is the nation’s largest estuary. After slow deterioration for several centuries, the Chesapeake Bay Program was launched in 1983 to restore it. After spending more than $24 billion, the results of the restoration program are disappointing. The Bay Program has arrested the decline of the Bay, but it has failed to achieve its restoration goals—something that will become more challenging with climate change. The rate of environmental change today is more rapid than at any time in the history of humanity. The concept of restoration—to return to an earlier time and condition—is an outmoded concept for coastal ecosystems like the Chesapeake Bay that are at the leading edge of change. A better strategy would be to focus on shaping the future Bay. While we cannot create the future Bay, we have many of the tools to shape it, tools that have never been used as a complement to existing efforts. Learn about the past and present of the Bay, how climate change will affect its future, and how we can intervene to shape the future of the Chesapeake.

Book excerpt: From the days of the Powhatan Indians to the establishment of Middle Plantation nearly 400 years ago, from its rise to power for a hundred years as the capital of England's largest North American colony to its decline into as many years of obscurity, Williamsburg has been shaped by the forces of history. Beneath the remarkable surface of today's restored colonial city lies an even more fascinating glimpse into the life of a community that has weathered the full sweep of American history.
Download or read book The Enduring Journey of the USS Chesapeake Navigating the Common History of Three Nations written by Chris Dickon and published by Arcadia Publishing. This book was released on 2008-07-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fight "til she sinks, boys. Don't give up the ship! Burn her." James Lawrence's command, spoken as his final fighting words in the historic 1813 battle between the USS Chesapeake and the HMS Shannon, would endure as the motto of the U.S. Navy. He lost the battle, however, and a large portion of the Chesapeake was recycled by the ship breakers of Portsmouth, England, until her timbers gave form and size to a new water mill in the village of Wickham. Almost two hundred years later, the old mill sat derelict, an eyesore. What was it made of ? Where had it come from? Why should it be preserved? It was then that the sails of a long-forgotten fighting ship were seemingly unfurled along the Meon River in the County of Hampshire, and the old navy frigate--having crossed the waters of America, Canada and England--set off on the third century of her enduring journey.
Download or read book Disturbing the Solar System written by Alan E. Rubin and published by Princeton University Press. This book was released on 2021-11-09 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The solar system has always been a messy place in which gravity wreaks havoc. Moons form, asteroids and comets crash into planets, ice ages commence, and dinosaurs disappear. By describing the dramatic consequences of such disturbances, this authoritative and entertaining book reveals the fundamental interconnectedness of the solar system--and what it means for life on Earth. After relating a brief history of the solar system, Alan Rubin describes how astronomers determined our location in the Milky Way. He provides succinct and up-to-date accounts of the energetic interactions among planetary bodies, the generation of the Earth's magnetic field, the effects of other solar-system objects on our climate, the moon's genesis, the heating of asteroids, and the origin of the mysterious tektites. Along the way, Rubin introduces us to the individual scientists--including the famous, the now obscure, and the newest generation of researchers--who have enhanced our understanding of the galactic neighborhood. He shows how scientific discoveries are made; he discusses the uncertainty that presides over the boundaries of knowledge as well as the occasional reluctance of scientists to change their minds even when confronted by compelling evidence. This fresh historical perspective reveals science as it is: an imperfect but self-correcting enterprise. Journeying to the frontiers of knowledge, Rubin concludes with the exciting realm of astrobiology. He chronicles the history of the search for life on Mars and describes cutting-edge lines of astrobiological inquiry, including panspermia (the possible transfer of life from planet to planet), the likelihood of technologically advanced alien civilizations in our galaxy, and our probable responses to alien contact. Authoritative and up-to-date but also entertaining and fluidly written, Disturbing the Solar System will appeal to any reader who has ever picked up a rock or gazed at the moon with a sense of wonder.
Download or read book After the Dinosaurs written by Donald R. Prothero and published by Indiana University Press. This book was released on 2006-07-13 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating study of the thousands of new animal species that walked in the footsteps of the dinosaurs—and the climate changes that brought them forth. The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth’s history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures―including our own ancestors. Their story is part of a larger story of new life emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth’s vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles. Life in the sea underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales. Engaging and insightful, After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.

Download or read book Invasion and Insurrection written by Jeffery M. Dorwart and published by Associated University Presse. This book was released on 2008 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book seeks to discover when, why, and how Delaware Valley communities, between 1621, when the Dutch West India Company issued instructions for the security and defense of the Delaware River until 1815, as the region abandoned its Committee of Defense of the Delaware at the end of the War of 1812, first used military force to repel invasion in times of war and suppress insurrection in peacetime. It traces how these mid-Atlantic communities confronted constant threats from real or imagined enemies, invasion and insurrection from earliest seventeenth-century settlement, and articulated ideas and built institutions for security, defense, and war. It argues that from the beginning these Delaware Valley communities failed to differentiate between their concert for defense against external attacks or invasion in wartime with that of providing security for their home communities against internal enemies durins peacetime. Though conflicted about using force both to defend against invasion and suppress insurrection, over time as the Delaware Valley communities moved to the center of colonial wars, revolution, and establishment of a republic and constitutional government, their long experience with security, defense, and war that blurred the lines between military defense in wartime and preserving peacetime security eventually fused into Article 1, section 8 of the U.S. Constitution to "empower the congress to use the militia to repel invasion and suppress insurrection." Jeffery M. Dorwart is professor of military, naval, and New Jersey history at Rutgers University.
Download or read book Biological Invasions in Marine Ecosystems written by Gil Rilov and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.
