Resumen:
Emission of the trace gas dimethylsulphide (DMS) from the ocean influences the2 chemical and optical properties of the atmosphere, and the olfactory landscape3 for foraging marine birds, turtles and mammals. DMS concentration has been4 seen to vary across seasons and latitudes with plankton taxonomy and activity,5 and following the seascape of ocean?s physics. However, whether and how does it6 vary at the time scales of meteorology and day-night cycles is largely unknown.7 Here we used high-resolution measurements over time and depth within8 coherent water patches in the open sea to show that DMS concentration9 responded rapidly but resiliently to mesoscale meteorological perturbation.10 Further, it varied over diel cycles in conjunction with rhythmic photobiological11 indicators in phytoplankton. Combining data and modelling, we show that12 sunlight switches and tunes the balance between net biological production and13 abiotic losses. This is an outstanding example of how biological diel rhythms14 affect biogeochemical processes.
