Water carries (IIRC) ~375x the energy of air per speed/unit volume. Depending on the turbine design, you don't need to filter anything. The currents (gyre power) are far more consistent than wind turbines. If not for the difficulties of siting, permitting, and maintaining subsea equipment, gyre power systems are far superior.
