Methane concentration and aerobic methane oxidation rate measured during RV Sonne cruise SO266 offshore SW Taiwan

Methane concentrations of discrete water samples were analyzed using the batch mode of a Greenhouse Gas Analyzer (GGA, Los Gatos Research) following the procedure described by Geprägs (2016). Methane oxidation rate (MOx) measurements were implemented as described by Bussmann et al. (2015) and Mau et al. (2013). Bussmann, I., Matousu, A., Osudar, R., and Mau, S. (2015).
