The new earth epoch Anthropocene needs a reference point on the planet. Research leader Francine McCarthy explains why Canada’s Crawford Lake beat out its 11 competitors.
Francine McCarthy from Brock University near Toronto and her international research team prevailed over twelve competitors with their proposal for the reference point of the Anthropocene. The geologist and earth system scientist researches earlier environmental conditions with the help of so-called microfossils. She is a member of the Anthropocene Working Group.
How did you come up with nominating Lake Crawford as a reference site for the Anthropocene?
The lake has long been known among geologists for providing a complete archive of sediments over a long period of time. Jock McAndrews and his colleague Maria Boyko were the first to describe it.
