Abstract An experiment was conducted in which a three component drag probe was used to measure the three directional components of turbulent velocity. While velocity measurements were being made, water samples were taken and analyzed for salinity and suspended particulate matter. Three dimensional energy spectra were computed from the velocity records between .1 and 5 Hz. These were compared with theoretical values. In the wave-number ranges corresponding to the
inertial subrange the spectra showed good agreement with the -5/3 power law. Reynolds stress tensors were computed. The norms of the Reynolds' stresses were used in a multilinear Regression model for particulate matter concentration and vertical variability of particulate matter concentrations. Although crude, the models accounted for over 60 percent of the variability in measured concentrations and over half the variability in vertical coefficient of variation.
