Turbulence and mixing is both ubiquitous in the environment of planktonic organisms and a critical part of large-scale physical and chemical oceanographic budgets. Recent studies have shown conflicting results about whether zooplankton contribute to ocean mixing and whether turbulence affects zooplankton feeding and swimming behavior positively, negatively or not at all. At least some of the confusion likely arises from the lack of properly resolved, simultaneous and co-located observations of zooplankton and turbulence. This talk introduces and discusses results from preliminary deployments of a Video Plankton Recorder – Vertical Microstructure Profiler (VPR-VMP), which is shown to provide this type of data. There is evidence of avoidance of the VPR -VMP by krill, which raises questions as to whether any microstructure profiler can accurately assess krill-generated mixing.
