[08-Aug-18] Dr. Emmanuel Boss readies an Underwater Vision Profiler (UVP), which will be used by scientists from UMaine and UA Fairbanks to collect water samples on the EXPORTS cruise. The UVP is designed to study large (>100 µm) particles and zooplankton and to quantify them in a known volume of water. The UVP system makes use of computerized optical technology with custom lighting to get digital images of zooplankton in situ. It can be used down to depths of 6000 meters (19,685 ft) below the surface.
