The late Eocene Chesapeake Bay impact structure is among the largest and best preserved impact craters on Earth.
The subsurface structure of the Chesapeake Bay crater is constrained by several shallow coreholes, marine seismic-reflection surveys, and gravity analyses. Major subdivisions of the structure are a circa 38-km-diameter central crater, enclosed by a 24-km-wide annular trough.
Research topics include studies of impact processes, regional basin evolution (comparing impact effects with "normal" effects produced by tectonics, global sea-level, and sediment supply on a passive continental margin), hydrogeology, borehole and regional geophysics, and the deep biosphere.
