The History of Our Planet Revealed


P. Jeffrey Fox
Director of Science Services
Integrated Ocean Drilling Program

The layers of sediment and rock that floor the global ocean contain an exemplary record of our planet's history over the last 200 million years. Jeff Fox will discuss how scientists recover samples and data from deep below the sea floor, and how investigations provide insights about how our planet works including character and causes of climate change and evidence of extraterrestrial impacts and mass extinctions.
