註釋

Velocity and temperature fluctuation measurements were made over the open ocean from instruments mounted on the R/V ACANIA. These data were examined to determine the validity of present formulations and prediction techniques. Values of momentum flux, were inferred from the rate of dissipation of turbulent kinetic energy, epsilon. Dissipation values were obtained from spectral estimates and inner scale estimates. The momentum flux, computed from spectra, supported the constant-flux assumption for neutral conditions. For periods of instability, the stability corrections applied to the vertical variation of epsilon resulted in the proper adjustments toward the predicted slope. The shape of a spectrum of temperature fluctuations was in agreement with predictions. (Modified author abstract).
