PCO2 CARIOCA Buoy
CARIOCA is an automatic drifting or fixed buoy designed to measure the concentration of pCO2 at the surface of the ocean in order to qualify the CO2 exchange between atmosphere and ocean. The buoy is equipped with the pCO2 sensor of NKE Instrumentation that used a revolutionary approach based on spectrophotometry.
CARIOCA buoy performs hourly measurements of several parameters:
Concentration of seawater dissolved pCO2
Sea Surface Temperature (SST)
Practical Salinity
Fluorescence
Air temperature
Atmospheric pressure
Dissolved Oxygen
