Variabilities of biochemical properties of the sea surface microlayer: insights to the atmospheric deposition impacts

During a six-month field campaign within BiREADI CSF IP-2018-01-3105 project, a comprehensive measurements of atmospheric and sea surface samples were obtained at the Adriatic coastal area. A strong impact of local/regional open-fire biomass burning (BB) sources likely supplied a substantial amount of N species to the sea surface microlayer (SML) and promoted the development of autotrophic and heterotrophic organisms, leading to a shift in the biological community toward small cell organisms. Consequently, atmospheric deposition associated with BB emissions played an important role in organic matter enrichment in the SML, which could have strong implications for global biogeochemical processes mediated by SML. This work demonstrates the importance of studying the short-term scale interactions between the atmosphere and ocean compartments, which can lead to a significant improvement in understanding of the ocean‐atmosphere system, with important implications for climate change.
