Finescale measurements of Kelvin-Helmholtz instabilities at a Kuroshio seamount

Data supporting the results presented in 'Finescale measurements of Kelvin-Helmholtz instabilities at a Kuroshio seamount', Journal of Physical Oceanography DOI 10.1175/JPO-D-24-0235.1
Fine-scale properties of Kelvin–Helmholtz (KH)-like shear instabilities on the trailing edge of a nonlinear lee wave generated by the Kuroshio impinging on a seamount were measured using a towed CTD chain, shipboard ADCP, and echosounder. Lee-wave vertical velocity amplitudes vary in phase with the upstream semidiurnal along-stream current. The instabilities are analogous to atmospheric billows induced by a recirculation on the trailing edge of mountain lee waves. A total of 135 KH billows were identified in a 4-day-long time series roughly 300 m downstream of the center of the lee wave. The KH billows have heights H=52+-11 m, widths L=162+-72 m, and aspect ratios H/L=0.39+-0.18. Positive reduced shear squared S2-4N2 (where S is the vertical shear magnitude and N is the ..., , # Data from: Finescale measurements of Kelvin-Helmholtz instabilities at a Kuroshio seamount
