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.

"In 2005 and 2006, an international deep drilling project, conceived and organized under the auspices of the International Continental Scientific Drilling Program and the U.S. Geological Survey, continuously cored three boreholes to a total depth of 1.766 km near the center of the Chesapeake Bay impact structure in Northampton County, Virginia. This volume presents the initial results of geologic, petrographic, geochemical, paleontologic, geophysical, hydrologic, and microbiologic analyses of the Eyreville cores, which constitute a step forward in our understanding of the Chesapeake Bay impact structure and marine impact structures in general. The editors have organized this extensive volume into the following sections: geologic columns; borehole geophysical studies; regional geophysical studies; crystalline rocks, impactites, and impact models; sedimentary breccias; post-impact sediments; hydrologic and geothermal studies; and microbiologic studies. The multidisciplinary approach to the study of this impact structure should provide a valuable example for future scientific drilling investigations."--Publisher's description.

Nonnative Oysters in the Chesapeake Bay discusses the proposed plan to offset the dramatic decline in the bay's native oysters by introducing disease-resistant reproductive Suminoe oysters from Asia. It suggests this move should be delayed until more is known about the environmental risks, even though carefully regulated cultivation of sterile Asian oysters in contained areas could help the local industry and researchers. It is also noted that even though these oysters eat the excess algae caused by pollution, it could take decades before there are enough of them to improve water quality.

"The third volume of the series “Large Meteorite Impacts” provides an updated and comprehensive overview of modern impact crater research. In 26 chapters, more than 90 authors from Europe, the United States, Russia, Canada, and South Africa give a balanced, firsthand account of the multidisciplinary field of cratering science, with reports on field studies, geophysical analyses, and experimental and numerical simulations. Nine chapters focus on structure, geophysics, and cratering motions of terrestrial craters. Recent advances in impact ejecta studies and shock metamorphism are assembled, each with seven chapters, and three chapters extend the scope from a terrestrial to a planetary perspective."--pub. desc.
