Acoustic Doppler current profiler and towed thermistor chain measurements made in the seasonal thermocline in the Norwegian Sea are examined for evidence that near-inertial shear leads to small-scale ''turbulent mixing'' (as inferred from meter-scale temperature fluctuations). For the ≈1 day of data examined here, spatial variability in shear is dominated by near-inertial waves having upward energy propagation, ≈30-m vertical wavelength, and 5- to 10-km horizontal extent (≈20-km wavelength). Repeated samples of one of these waves had high Froude number and enhanced small-scale variability dominated by ≈20-m-long waveforms which we conjecture are Kelvin-Helmholtz instabilities arising from the near-inertial shear.
