Multiscale variability is a striking feature of geophysical phenomena. This is true of the earth's subsurface where the medium varies rapidly in all directions. Fine-scale random processes and multiscale fractals provide the framework to mathematically characterize the variability. This session emphasizes empirical and theoretical considerations for waves and radiative transport in these media. The speakers will present practical experience on wave interactions with 3-D heterogeneity, multiscale analysis findings on detailed medium measurements, and theoretical results. One basis for these results is a separation of scales, providing a generalization of the O'Doherty-Anstey formula. Another is the application scale-invariance or transport theoretical arguments.
