Gases were measured with underwater and autonomous sensors with a frequency of 1 measurement per minute for durations of 8 to 20 days between December 2021 and December 2022. The data also show the salinity, temperature, pressure and O2 concentration interpolated to 1 min interval. The air-sea fluxes of CH4 (FCH4) are given in nmol m-2 min-1, and calculated using the equation k600(CH4 )= -1.07 0.36v + 0.99u +0.87h from Rosentreter et al., 2017.Empty cells = nd
