With the ship's system water temperature and salinity was recoreded, as well as the wind speed. Atmospheric concentrations were measured with a LICOR trace gas analyzer. Dissolved methane was determined via a degassing system connected to a greenhouse gas analyzer as online measurements. Theses relative concentrations were converted to concentrations with water samples analyzed with gas chromatography.
