Comment:
Atmospheric gas concentrations of CH4 and CO2 were measured with Picarro G2301-f analyzer.
3 gas inlets were placed at three different positions onboard RV Poseidon; continuous measurements with gas from each inlet every 3 minutes.
Concentrations are given as “ppmV in dry air”.
Concentrations are correlated with GPS-position (DSHIP) using time stamps (UTC); calculated 1-3s averages.
