The Pivers Island Coastal Observatory (PICO) closed 2016 by reaching a major milestone – the 750th time point! Started in mid-2010 as an undergraduate independent student project focusing on ocean acidification, the coastal time-series has matured into a long term coastal sentinel, observing seasonal, yearly and interannual changes in the physics, chemistry and biology of the coastal marine environment with weekly sampling. Additional offshore longitudinal sampling (PICO-LOVE) provides spatial context. Data is available through BCO-DMO. Congratulations team PICO!
