Deep tree roots bring respiring microbes into broken bedrock, generating carbon that’s released into the environment. New research explores this oft-overlooked carbon source.Read More »Biogeosciences
A new study refines our understanding of marine residence times of iron, which supports carbon-sequestering sea life, offering valuable data to inform biogeochemical models.Read More »Biogeosciences
By comparing measured volcanic output with subducted carbon fluxes from drill cores, the Lesser Antilles subduction zone shows nearly complete slab carbon release at sub-arc depths.Read More »Geochemistry, Mineralogy, Volcanology
Researchers validated some steps in the standard sequential chemical technique used to extract different forms of iron from rock samples but found inconsistencies in other steps.Read More »Biogeosciences
An innovative collaboration is investigating how geobiological processes alter fluxes of carbon and other materials between the deep Earth and the surface.Read More »Geochemistry, Mineralogy, Volcanology
Dissolved thorium isotopes light the way to a more thorough understanding of how different elements enter marine environments—and how long they stay there.Read More »
