Autonomous Vertically Profiling Plankton Observatory (AVPPO)

OBSERVATORY OVERBOARD—Scientists and crew aboard R/V Connecticut lower the Autonomous Vertically Profiling Plankton Observatory (AVPPO) to the seafloor. The AVPPO carries instruments that record changing conditions in the coastal ocean, including its temperature, salinity, motion, levels of chemicals and dissolved gases, and the numbers and kinds of organisms living in the area. Data are relayed via cable to the WHOI Martha's Vineyard Coastal Observatory. (Photo by Andrew Girard, WHOI)
