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.
