Isoprene, the most important biogenic VOC, has received increased attention in recent years as biogenic emissions of isoprene are the main contributor for secondary organic aerosols (SOA) formation. SOA in the atmosphere influence the radiative balance through scattering or absorption of solar radiation and, therefore, have a direct impact on the climate of our Earth’s system. The knowledge about the spatial and seasonal distribution of isoprene, as well as its production and consumption processes in the surface ocean, is still lacking and is crucial to quantify marine isoprene emissions. The main goal of this work was to increase the global dataset of marine isoprene measurements and provide a better understanding of the biogeochemical cycling in the surface ocean. This improved understanding was used to calculate the global surface isoprene distribution and the isoprene emission to the atmosphere in order to estimate the influence of marine isoprene on the Earth’s atmosphere and climate.
