List plotting a vector field containing invalid data

I'm solving a 2D CFD problem, which is generating a lot of co-located 2D
velocity field data, using a regular rectangular grid.  Some of the grid is
masked out, representing ocean bottom topography.

Is there a relatively simple way to modify ListPlotVectorField to ignore the
masked out values (which are stored as as unphysically large values, but this
is easily modified)

Thanks.
