The data are the methane (CH4) concentrations and partial pressures measured in a Red Sea coastal lagoon seagrass bed and adjacent mudflat, and in a coral reef lagoon. 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. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.948547"! ** Empty cells = nd This work was funded by the Baseline funds of Michael Berumen and the Academic Space, Equipment and Planning Committee (ASEPC) at the King Abdullah University of Science and Technology, KAUST
