Catlin Arctic Survey winter 2011 copepod ocean acidification experiment.

Physicochemical and biological data from a copepod ocean acidification experiment conducted in the Canadian high arctic in later winter 2011. Data are for four copepod 'types': Adult Calanus copepods; Adult Oithona copepods; large nauplii (>200 µm) and small nauplii (<60 µm). Measured data are survival rates, respiration rates and heart beat (adult Calanus copepods only). Calculated carbonate system data (pCO2, pH, HCO3, CO3, Calcite and aragonite saturation states) are calculated using measured temperature, salinity, DIC and TA taken from the experimental containers.
