Methods & Sampling

Dataset acquisition description

For MAPCO2 Buoy Information See: SO-GasEx cruise report, Section 5.5.1 pgs 30-33

The SO-GasEx MAPCO2 buoy contained a MAPCO2 non-dispersive infrared analyzer based system for measuring the CO2 concentrations of the surface water and atmosphere every 30 minutes. A Gill sonic anemometer measured the wind speed and direction at approximately 0.9m above the water surface. A 10 minute average reading was recorded every 30 minutes. A SeaBird 37 Microcat sensor measured the temperature and conductivity of the water at approximately 1m depth every 15 minutes. All of these data, together with the GPS location of the buoy, were transmitted via Iridium satellite to NOAA/PMEL four times per day.

MAPCO2 Drifting Buoy

Supplied Description:

For SO-GasEx MAPCO2 Buoy Configuration See:
SO-GasEx MAPCO2 Metadata Report

Instrument Type

Generic Name: MAPCO2 Drifting Buoy

Acronym: MAPCO2

Generic Description:

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.
