CH4 production during incubations with additions of 1 µM acetate, 1 µM methanol, 1 µM dimethylsulfoniopropionate (DMSP), 1 µM methylphosphonate (MPn), 1 µM methanthiol (MeSH), and 1 µM trimethylamine (TMA) at sites P1 (a, near-shore site, water depth 19 m), P5 (b, offshore site, water depth 87 m) and S4 (c, offshore site, water depth 104 m); biological production of CH4 in surface waters at site S2 (near-shore site, water depth 48 m) with C:N (1060 µM glucose:160 µM nitrate) or C:N and 10 µM MPn additions (d); CH4 production in offshore waters at P5 station amended with 10 µM inorganic phosphorus (Pi), 10 µM MPn and 10 µM MPn + fluoromethane (CH3F) after adjusting C:N ratio (e); changes of dissolved inorganic phosphorus (DIP) concentrations in offshore surface waters at site S3 (offshore site, water depth 87.5 m) with 5 µM MPn addition (f). Data are presented as mean values and error bars represent standard deviation of triplicate samples.
