Mean vertical velocities with associated confidence intervals versus energy dissipation rates collected at Woods Hole Oceanographic Institution in 2011 (Larvae in turbulence project)

Expand/Collapse All

Description

Mean vertical swimming velocities and 95% confidence intervals for two experiments (OY5 and OY6) with four trials each (Trials 1-4) calculated according to the method described in Wheeler et al (2013). PIV recordings were performed by J. Wheeler in Summer 2011 and 2012.

Data Processing Description

PIV velocity vectors extracted from raw images using DaVis image processing software, as described in Wheeler et al. 2013. PIV velocity vectors are isolated near larvae and used to subtract out local flow near larvae to identify larval velocities, as described in Wheeler et al. 2013. Averages and confidence intervals for larval velocities calculated using Matlab. See related metadata turbulence tank base measurements for information on calculation of energy dissipation rates.
