The
Initial Science Plan of the current IODP program lists ÒSolid Earth Cycles and
GeodynamicsÓ as a central theme. Centered around geologic processes driven by
outer core and mantle convection, this theme was designed to examine both the
creation, destruction (recycling), structure, and movement of oceanic crust and
lithosphere, the rifting of continents, and large igneous provinces. Within
this theme were described four initiatives: 1) Continental Breakup and
Sedimentary Basin Formation; 2) Large Igneous Provinces; 3) 21st Century
Mohole; 4) Seismogenic Zone.
Should
the next phase of IODP (2013-2023) focus on similar issues and initiatives? If
so, why and what are the unsolved elements of these research foci? If not, what
are the most compelling unresolved issues in solid earth processes that can be
investigated through scientific ocean drilling? How can investigation of these
basic processes contribute to mitigation of geodynamic impacts on humans?
(e.g., tsunamis, volcanoes, earthquakes, environmental response to catastrophic
volcanic events as analogs to greenhouse gas loading of the atmosphere).
