The three basic observational approaches to estimating turbulence parameters in
continental shelf seas are free-fall micro-structure probes from which dissipation is inferred;
fast-sample (10–20Hz) current meters in sea-bed frames measuring turbulence intensity
directly; and fast-sample O (1Hz) high-frequency Acoustic Doppler Current Profilers
(ADCPs) where Reynolds stress profiles and hence turbulence production can be estimated
from the variance of the along beam data. Uncertainties are associated with each approach …
