Climate scientists Nicholas Balascio and Francois Lapointe working with an ice auger to drill in the 3.5m thick ice at South Sawtooth Lake, Ellesmere Island, Nunavut Territory, Canada. An ice auger extension is needed because the ice is so thick. Coring lake sediments can only be done after this tedious […]

These giant mounds of fossil stromatolites from about 2.5 billion years ago are located in South Africa. For scale, notice a person’s dangling legs at the top center. These layered minerals were deposited on an ancient coastline by communities of microbes, including photosynthetic bacteria that generated oxygen. The new study […]

Merrill Brook forest in Dartmouth’s Second College Grant, N.H. Photo by Matthew Ayres. A Dartmouth-led study examining carbon stocks in an actively managed mixed wood forest in New Hampshire finds that places with more trees have more carbon stored in both the trees and the soil. The findings, published in Forest Ecology and […]
