Globally integrated kinetic energy ($KE$; a and b), available potential energy ($APE$; c and d), energy dissipation rate (e and f), and $k\sin \chi$ values (g and h), for ${\mathrm{M}}_2$ (left‐hand side subplots) and ${\mathrm{O}}_1$ (right‐hand side subplots) ocean tide simulations with different values of $T$ in Equation 6, and the four bathymetries shown in Figure 1. Four additional $T$ values were used in the 55 Ma simulations, in order to better resolve the peak near 22 hr. Globally integrated $KE$ and $APE$ values are computed via Equation 13. This figure, and all subsequent figures, have legends, and the legends are not enclosed by boxes.
