B. EKE
- SLA rms and mean EKE.gif.

- Patch of EKE: 151°E-155°E and 8°S-5°S:
time series of SLA.gif;  spectrum of SLA.gif.

Variance of the full signal: 139.6 cm2
Variance of the low frequency signal: 77.29 cm2
Variance of the high frequency signal: 15.11 cm2 (half power 180 days)

- rms of HF SLA.gif; mean surface circulation.gif

- EKE signal for the Low frequeny signal.gif, and the High frequeny signal.gif
- Time series of the EKE signals for the full, low, and frequencies: eke_ft.gif
- Spectrum of sqrt(EKE) (relative to velocity field) : spe_uv.gif

Mean eke for the full signal: 682 (cm/s)**2
Mean EKE for the low frequency signal: 169 (cm/s)**2
Mean EKE for the high frequency signal: 413 (cm/s)**2
