Video Plankton Recorder


The Video Plankton Recorder (VPR) is an instrument usually towed behind the ship, and is being recovered here. It makes controlled dives and climbs in the water column. A camera records images of zooplankton at approximately 10 mph. The images can be viewed via cable to ship computer to measure size as well as type and abundance. 4/10/2007.(Photo by Andrew King.)
