Air – sea exchange processes of marine-derived trace gases at the land-coastal interface potentially impact climate, air quality, and human health. These processes need to be explored in order to close gaps in the understanding of the effect of concentration variation, emission strengths, and sources. Applying the novel technology of drones, including remote imaging, opens new dimensions of accessibility and flexibility that will address open scientific questions of air-sea exchange along coastal boundaries. We will conduct discrete air sampling with subsequent analysis of >50 trace gases across the surf zone. Concurrent imaging with the sampling will for the first time differentiate between advective and near-coastal processes, such as wave breaking, on the ambient gas concentrations.
