and to form oceanic crust. Plates come together or converge at subduction zones which mark the locations where one plate plunges beneath another, returning crustal material to the mantle. The continuous movement of the plates therefore acts to recycle material between the Earth's crust and underlying mantle. This expedition is about volatile recycling along the Central American subduction zone and involves a number of scientists using different techniques in a collaborative approach. Read on!
