Abstract
  • The authors report direct measurements of density flux at a single depth in a turbulent tidal flow, made by towing a CTD beside the vertical beam of a modified acoustic Doppler current profiler. The direct flux estimates are compared with indirect estimates of density flux based on simultaneous microscale profiler measurements of ϵ and χ, dissipation rates of turbulent kinetic energy and of temperature variance, respectively. Two mixing efficiency estimates are made using Γ𝒹 from the ratios of indirect flux estimates and Γ₀ from the ratio of direct to ϵ flux estimates. The analysis indicates that • Γ𝒹 is no different from that determined in other open ocean experiments and is independent of the sign of the flux • Γ 𝒹 < |Γ₀|, regardless of the sign of the flux • Γ₀ (flux > 0) < |Γ₀| (flux < 0). The consequences for interpretation of ocean microstructure flux estimates are discussed.
