Localized Degenerate Control of Navier-Stokes

For incompressible Navier-Stokes on Td\mathbb{T}^d, d=2,3d=2,3, is the system approximately controllable and/or controllable in finite-dimensional projections by a localized degenerate forcing, where the control space EE is a finite-dimensional subspace of {uV:suppuD}\{u\in V:\operatorname{supp}u\subset\overline{\mathcal D}\}? Construct such an EE independently of the viscosity ν\nu.
