The proposal for the M2M project was submitted on April 1st, 2012 to IODP. It is an international project led by Susumu Umino (Kanazawa University, Japan), Benoit Ildefonse (CNRS, Université Montpellier 2, France), Peter Kelemen (LDEO, Columbia University, USA), Shuichi Kodaira (JAMSTEC, IFREE, Japan), Katsuyoshi Michibayashi (Shizuoka University, Japan), Tomoaki Morishita (Kanazawa University, Japan), and Damon Teagle (NOCS, Southampton, UK).

Sketch of the plate tectonic cycle showing the upwelling and partial melting of asthenospheric mantle to form new ocean crust at a mid-ocean ridge and the progressive growth of the lithospheric mantle as the plate conductively cools away from the ridge until it is subducted back into the mantle. Beneath the continental shields there is commonly a deep keel of continental lithospheric mantle that has been isolated from mantle convection since the Pre-Cambrian. The MoHole (thick yellow line) will sample the upper part of the oceanic mantle lithosphere, which is eventually recycled at subduction zones. Figure by Christopher Smith-Duque.
