| Definition | A submersible imaging sensor designed to study large (>100 µm) particles and zooplankton simultaneously and to quantify them in a known volume of water. The UVP sizes marine snow, aggregates > 100 µm and images plankton > 500 µm and can be operated as a stand-alone system or deployed on a Rosette frame, ROV, AUV or mooring. The UVP5 acquires only in-focus images in a volume of water delimited by a light beam issued from red light-emitting diodes (LEDs) in 100 µs flashes. The typical light beam illuminates an area of 4x20 centimetres which gives a sampling volume of 1 litre per image. When interfaced with conventional CTD measuring devices, the distribution of particles and fauna can be displayed in real time integrated with the CTD metadata. The high-resolution digital image can then be processed by the computer. Optional telemetry. The imaging rate is 20 images per second. The system is depth-rated to 600 m. | |
