This project is the development of an experimental set-up that will be used to investigate the diel vertical migration (DVM) of zooplankton, Daphnia magna in this experiment, and the effects that DVM has on biomixing. The experiment will produce flow fields that will be used to draw conclusions on zooplankton’s role in biomixing. DVM is heavily dependent on light as a driving factor, zooplankton escape from light in the field but swim towards light in the lab. Therefore, this phototactic behavior will be taken advantage of to drive DVM in the experiment through LED lights. The images from a camera tracking the spatiotemporal distribution of zooplankton, will be used to obtain flow fields through particle image velocimetry (PIV) and particle tracking velocimetry (PTV). These flow fields will provide information such as dissipation rates of hydrodynamic tails, allowing the scale of zooplankton mixing to be investigated. Zooplankton are an essential aspect of the aquatic systems and understanding the scale at which DVM influences biomixing provides insight into the role of DVM in processes such as the carbon cycle and biological productivity.
