Chesapeake Bay Impact Crater
To understand how a meteorite impact 35 million years ago negatively affected ground-water availability in southeastern Virginia.
This project is working to understand how a comet/asteroid that crashed into Chesapeake Bay 35 million years ago has influenced modern groundwater supplies in southeast Virginia. An international scientific workshop developed plans for drilling a 2-kilometer-deep corehole through the center of the crater. This core, which was drilled in 2005, was financed primarily by the International Continental Scientific Drilling Program. The results from this deep core, other cores already drilled nearer the crater margin, and geophysical data, are providing an unprecedented amount of information about how craters are formed, and specifically about how this crater led to salty ground water in the Hampton Roads area of Virginia.
