ABSTRACT:
A bioluminescent detector is disclosed for detecting and measuring in situ bioluminescence generated by marine microorganisms. The detector includes a laminar flow chamber, a turbulent flow chamber in fluid communication with the laminar flow chamber, and a photon detector network positioned with the turbulent flow chamber. The detector is dropped over the side of a ship which may be underway and sinks at constant velocity. As the detector descends, ocean water flows through the laminar flow chamber and then into the turbulent flow chamber where fluid turbulence subjects any bioluminescent organisms present to shear stress, causing them to generate photons that are detected by the photon detector network.
