Research assistant Jennifer Williams (Earth and Environmental Systems Institute) points out soil properties to post doctoral scholar Lin Ma (geosciences) during soil sample collection at the Shale Hills Critical Zone Observatory.
The researchers sampled 21 sites along a ridge at Shale Hills. They took core samples from the surface down to bedrock. At 20 of the sites they found elevated manganese. The core samples, which are about 12 inches long, encompass about 7,000 years of soil formation. For additional information about this research, go to live.psu.edu/story/50332
