 Solving Subduction Zone ‘Headaches’

New Approach to Solving Subduction Zone ‘Headaches’

A new way of determining the amount of carbon entering a subduction zone, where an oceanic plate sinks beneath a continental plate, could lead to better estimates of the global movement of carbon into and out of the deep Earth.
