Scientists exploring an ancient impact crater deep below the mouth of the Chesapeake made an unexpected discovery recently: a sea that is between 100-150 million years old. The discovery will help researchers understand what shaped our continent long ago, and perhaps most exciting, to study a period that could offer clues about the effects of climate change. We explore the ancient sea with one of the lead scientists on the project.
This computer simulation illustrates how an asteroid contributed to the formation of the Chesapeake Bay impact crater. Light brown symbolizes sediment and water, while the gray color symbolizes hard rock. *Note: there is no audio in this video. (Credit/Gareth S. Collins and Kai Wünnemann/Geology)
