Fig. 3. Turbidity current structure and duration from ADCP measurements at the 2009–2010 mooring site.

Fig. 3

(A) Full velocity time series for 3 months in 2009–2010 (5), showing that flows are active for ~33% of the time. Single flow in (B) to (D) is shown by the red box. (B) Horizontal velocity (30-min averages). (C) Intensity of large-scale velocity fluctuations, defined as the root mean square of differences between individual velocity measurements and 1-min averages. (D) Sediment concentrations inverted from 300- and 75-kHz ADCP acoustic backscatter (see Materials and Methods and figs. S3 to S10). This analysis assumes that the flow contains a single grain size, and variations in grain size may cause artefacts such as higher concentrations above lower concentrations. (E to I) Velocity profiles for different parts of the flow. (J) All velocity profiles combined in one plot.
