Sommario:
  • Water sampling was conducted during AL575 cruise in the North Sea by using Niskin Bottles attached to CTD/Water sampler rosette and ROV (Haeckel and Schmidt, 2024). To detect methane anomalies in the water column derived from seafloor gas emissions the recovered water samples were processed by using headspace gas sampling and subsequent gas chromatographic analysis. Based on measured methane concentrations of headspace gas in (micro-atm) the dissolved methane concentrations in water were calculated (nmol l-1).
