Instrument: MAPCO2 Drifting Buoy


The Moored Autonomous pCO2 (MAPCO2) surface drifting buoy designed by NOAA/PMEL is a low profile, high payload buoy. It was used in the SO GasEx project as a drogued drifter instrumented with a variety of autonomous instruments capable of making a coordinated set of physical, geochemical, and biological measurements at high temporal resolutions. These measurements provide a key component in the study of processes controlling air-sea CO2 exchange.
