Description
Summary:The bioluminescence of two cultured planktons, Gonyaulax polyedra and Pyrocystis fusiformis and their utility as tool for flow visualization were investigated by testing their luminescent response to hydrodynamic stimuli in a fully developed piped flow. Both species were found to offer advantages for flow visualization. Results of the hydrodynamic calibration showed low threshold for bioluminescent stimulation for laminar flow. Although the values of shear stress necessary for bioluminescence was found to be greater than the ambient values of shear in an open ocean, consistency with antipredation function for bioluminescence was observed.
