In a recent Dartmouth College study, researchers tested how decomposition changes with soil depth to help predict whether deep soil carbon would be vulnerable to climate-induced changes.

“Deep soil carbon is a really big deal for understanding the future of climate change,” said Caitlin Hicks Pries, an assistant professor of biology at Dartmouth.
