We employ a sequence of Doppler images obtained with the CoronalMulti-channel Polarimeter (CoMP) instrument to perform time-distance seismologyof the solar corona. We construct the first k-omega diagrams of the region.These allow us to separate outward and inward propagating waves and estimatethe spatial variation of the plane-of-sky projected phase speed, and therelative amount of outward and inward directed wave power. The disparitybetween outward and inward wave power and the slope of the observed power lawspectrum indicate that low-frequency Alfvenic motions suffer significantattenuation as they propagate, consistent with isotropic MHD turbulence.
