Princeton’s Jeroen Tromp is part of a team using Oak Ridge National Laboratory’s (ORNL’s) Titan supercomputer, to reveal the Earth’s inner workings via adjoint tomography simulations, or monitoring the interaction of a forward wavefield, in which the waves travel from the source to the receivers, and an “adjoint” wavefield in which the waves travel inversely from the receivers to the source.
