Harry at the Cliffs
Detailed Description
Harry Dowsett is explaining the significance of these beds of the Calvert Formation that are exposed along Calvert Cliffs on the west side of the Chesapeake Bay. Beds 11, 12, and 13 (shown here) were deposited during the Middle Miocene Climatic Optimum, about 17 to 14 million years ago. Like today, the warming during the MMCO was driven by large and rapid CO2 emissions.

Geological Investigations of the Neogene explores past warmer-than-modern climates of the mid-Miocene (about 14-17 million years ago) and Piacenzian (about 3 million years ago) to assess the potential environmental and economic impacts to population centers along the US Atlantic coast under different rates and magnitudes of changes related to warmer temperatures. Specifically, we look at past...
