  abstract = {{M}ultiyear turbulence measurements from oceanographic moorings in equatorial {A}tlantic and {P}acific cold tongues reveal similarities in deep cycle turbulence ({DCT}) beneath the mixed layer ({ML}) and above the {E}quatorial {U}ndercurrent ({EUC}) core. {D}iurnal composites of turbulence kinetic energy dissipation rate, epsilon, clearly show the diurnal cycles of turbulence beneath the {ML} in both cold tongues. {D}espite differences in surface forcing, {EUC} strength and core depth {DCT} occurs, and is consistent in amplitude and timing, at all three sites. {T}ime-mean values of epsilon at 30 m depth are nearly identical at all three sites. {V}ariations of averaged values of epsilon in the deep cycle layer below 30 m range to a factor of 10 between sites. {A} proposed scaling in depth that isolates the deep cycle layers and of epsilon by the product of wind stress and current shear collapses vertical profiles at all sites to within a factor of 2.},
