Scientific paper

Surface gravity waves have been used to probe flows in the two megameters beneath the photosphere using the techniques of time-distance helioseismology. Realistic spatial kernels were calculated using the Born approximation and used in an iterative deconvolution to obtain an estimate of the subsurface horizontal flows. We detect an outward flow outside sunspots: the moat flow. Penumbral outward flows are also present, but appear to be smaller than the Evershed flow observed at the surface. The effect of the Coriolis force on supergranular motion has been measured.
