Positive tidal torque generated by oceanic eccentricity tides in super-synchronous frequency range (Ω > n_⋆) for increasing oceanic depths (a–f). An oceanic mode is characterised by a resonance of eigenfrequency σ_n (blue peaks). We focus here on the degree-0 mode, of frequency σ₀, in the non-rotating approximation (Coriolis effects are ignored). An eccentricity term of frequency σ_2,s = 2Ω − sn_⋆ generates a positive torque, which is enhanced by the resonance when (red peak). The semidiurnal (σ_2,2) and first eccentricity frequencies (σ_2,3 and σ_2,4) associated with the peak thus created are symbolised by the superscript ▲. The peak raised by the eccentricity tide occurs when , which also corresponds to and . The direction of peaks indicates the sign of the tidal torque. In the super-synchronous regime (σ_2,2 > 0), downwardblue peaks tend to drive the planet towards tidal locking in spin-orbit synchronous (σ_2,2 = 0), while upward red peaks tend to drive it away from this state of equilibrium.
