Materials From Arctic Shelves Are Changing the Water’s Composition

Materials from Arctic Shelves are Changing the Water’s Composition: Scientists say the input of shelf-derived materials to the central Arctic Ocean over the past decade appears to be increasing. They further note that this increase is altering the water’s composition and could threaten biological productivity and species assemblages. Their results provide one of the first […]

Composition of Earth’s Mantle Revisited

By on    Featured, Science/Education  

Research published last week in Science suggested that the makeup of the Earth’s lower mantle, which makes up the largest part of the Earth by volume, is significantly different than previously thought. The work, performed at the Advanced Photon Source at the U.S. Department of Energy’s Argonne National Laboratory, will have a significant impact on our understanding of the […]
