Extended Data Table 1 Mean turbulent properties

From: Intense upper ocean mixing due to large aggregations of spawning fish

  1. Mean values [95% confidence intervals in brackets], and/or median values () for the three sampling periods (I01, I02 and I03) and for times of biophysical and geophysical turbulence. Unless indicated, the averaging was performed over the 10–25 m depth range. The number of segments in which turbulent quantities were calculated, and were unaffected (ngood) or affected (nimpatcs) by impacts against the instrument, are indicated. The affected data were discarded and not used for computing averages. N2 is the buoyancy frequency (a measure of stratification); sh2, the vertical shear of the horizontal velocity; Rig = N2/sh2, the gradient Richardson number; ε the turbulent kinetic energy dissipation rate; χ, the thermal variance dissipation rate; KT, the turbulent heat diffusivity; Rf the flux Richardson number or mixing efficiency; LT, the Thorpe scale; LO the Ozmidov scale; FrT, the turbulent Froude number; ReT the turbulent Reynolds number; and Reb the buoyancy Reynolds number.
