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. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

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.

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.

Dinosaur memories are hard to forget! Most who revel in the current renaissance in dinosaur science, art, fiction and movies, or who enjoy the other appealing prehistoric animals so well popularized by the media have fond recollections of what it was like “growing up dinosaur.” Together with wife Diane and his father Allen G. Debus, Allen A. Debus unveils treasured dinosaur memories and stories about prehistoric animals and paleo-people, spanning from the cold-blooded dinosaur ‘era,’ to the modern wave dinosaur renaissance. Beginning with fondly recalled roadtrips to prehistoric places where T. rex still reigns, Dinosaur Memories ventures into the realm of thunder beasts and explores the rich ‘pop-cultural’ appeal of prehistoric animals. If you’ve ever collected dinosaurs, enjoyed fossil hunting or visits to see the old bones in museums, Dinosaur Memories is a book you’ll still recall years from now! Thirty-five chapters are grouped into seven sections titled, “Roads Into Prehistory,” “Thunder Beasts,” “Dinosaur Worlds,” “Fantasy Dinosaurs,” “Fossil Trickery,” “Paleo-people,” and “Rustlin’ up Dinos.”
