The MoHole: A Crustal Journey and Mantle Quest

June 3-5, 2010 – Kanazawa, Japan
Convener: Doug Wilson



Workshop_Mohole_ImageDrilling an ultra-deep hole in an intact portion of oceanic lithosphere, through the crust to the Mohorovicic discontinuity (the ‘Moho’), and into the uppermost mantle is a long-standing ambition of scientific ocean drilling, and remains essential to answer fundamental questions about the dynamics of the Earth and global elemental cycles. The 2010 MoHole workshop had two interconnected objective, which have been discussed jointly between ocean lithosphere specialists, marine geophysicists, and engineers:

  • To initiate a roadmap for technology development, and the project implementation plan, to achieve the deep drilling objectives of the MoHole project,
  • To identify potential MoHole sites in Pacific fast-spread crust, where the scientific community will focus geophysical site survey efforts over the next few years.
