Geodynamics Interest Group (GIG)

The Geodynamics Interest Group is a weekly group meeting of Geophysicists, Geodicists, Geochemists, Seismologists, Petrologists, and others in SOEST who are interested in the broadly defined topic of Geodynamics. We meet informally every week to discuss topics of interest and research occurring within SOEST. We communicate via e-mail: please contact Clint Conrad (clintc@hawaii.edu) to be added to the e-mail list.
