File content: ###### Sample list * Sample ID, sampling device, depth, lon-lat coordinates and time of sampling * Salinity, temperature, oxygen concentration and carbon dioxide concentration of the seawater * Concentration, δD and δ¹³C of dissolved methane in seawater ###### Triple isotope samples * Concentration, δD, δ¹³C and Δ¹⁴C for dissolved methane in select seawater samples * Regression analysis results for Keeling plots of δD, δ¹³C and Δ¹⁴C to obtain the methane isotope signature of the seafloor methane seeps ###### ¹⁴C results * ¹⁴C of dissolved methane and CO₂, and parameters that were used for these calculations The same data is also provided in three comma-separated values (csv) files, stored with Western Europe (ISO-8859-15/EURO) character set.
