Dataset: Large particulate matter concentration, biovolume, and sized distribution in the Pacific Ocean from 2015-04-11 to 2015-06-18 measured by the Underwater Vision Profiler 5 (UVP5) on the P16N Repeat Hydrography cruise aboard the NOAA Ship Ronald H. Brown

The Underwater Vision Profiler (UVP5) is an underwater camera system that was designed to record the vertical distributions of large aggregates and zooplankton (> 102 µm) down to 6000 m. Two units that consist of red-light emitting diodes (LEDs) illuminate (in 100 µsecond flashes) an area of 4 X 20 cm which provides a volume sampling of ~1L per frame. The UVP5 was mounted on the bottom of each CTD rosette and collected data on each CTD cast (data are collected during the down cast). The methodology generally follows Picheral et al., 2010.
