Model version definition

The Underwater Vision Profiler version 6 or UVP6 is designed to study particles and zooplankton simultaneously and to quantify them in a known volume of water. The UVP counts and sizes all objects > 60 µm and records images of aggregates and plankton > 620 µm. The UVP6 acquires only in-focus images in a volume of water delimited by a light beam issued from a red laser diode in ~100 µs flashes. The collimated light beam illuminates a sampling volume of ~0.6 litre per image and the pixel size is 73µm. The images can be acquired at up to 20Hz. The UVP6 is a very versatile system weighting 1.6Kg in water and consuming very low power. It has been utilised in long term mooring, cabled observatories, CTD-rosette frames, gliders, AUVs, profiling floats and drifting lines. When interfaced with conventional CTD measuring devices, the total abundance of particles can be displayed in real time, integrated with the CTD data. The system has a typical depth range of 6000 m. UVP6 fitted with a powerful image processor allowing to acquire and process images at up to 20Hz (max power = 6W).
