HKE (blue) and APE (red) of the diurnal (left panel) and semidiurnal (right panel) internal waves at moorings (a and b) Y1, (c and d) Y3 and (e and f) Y2. The HKE and APE have been lowpass filtered to eliminate the diurnal and semidiurnal oscillations of the diurnal and semidiurnal internal waves, respectively.
