..will be interesting what the lab analysis reveals. I wonder if it was an extinction+ level event when it hit 35 million years ago?
"This is one of the most complete cores ever obtained in an impact structure," said Koeberl, "and will allow us to understand a shallow-marine impact event at an unprecedented level."
The team successfully recovered the complete succession of post-impact sediments above the crater, the entire sequence of rocks broken up during the impact, and rocks from the crater floor. These samples will allow the project's international science teams to research the post-impact environment, impact-related processes, and the impact process itself. In addition, the team completed geophysical down-hole logging to collect additional data, such as the temperature gradient within the corehole.
Important in this multidisciplinary venture is the analysis of the groundwater reservoir in the Chesapeake Bay impact crater. Findings have direct implications for the millions of people living in the area along Virginia's eastern shore and to future development. Several teams from the U.S. and Europe are investigating the microbial life present in the impact crater, part of intriguing recent studies of life in exotic environments.
