We present direct experimental observations of collective transport in two-dimensional magnetic bubble arrays in thin garnet films. Shear flow is produced by forcing the array to move past a flat interface; the array is strongly pinned on the other side of the interface. Time-resolved images of the dislocation dynamics that produce shear flow are obtained via Voroni constructions.
