\n“Measurement of dissolved H2 and CO:Dissolved gases were also sampled in situ at each transect to measure dissolved concentrations of CO and H2. Serum vials (160\u2009ml) were filled with seawater using a gas-tight tube, allowing approximately 300\u2009ml to overflow. …H2 and CO concentrations in the Exetainers were analysed by gas chromatography using a pulse discharge helium ionization detector.”
