I define myself as a scientist covering multidisciplinary aspects of atmospheric science. Merging the local ICM-CSIC expertise and my large international network of collaborators, I have developed in Spain a new research theme - using both experimental and field approaches - linking aerosol emission processes with biological activities in surface waters. Applying urban quality related state-of-the-art techniques in the marine remote atmosphere allows us to explore unstudied aerosol processes. The multidisciplinary application of polar atmospheric science, marine biogeochemistry and microbial ecology techniques advocated in the recent years is being used to examine the potential of changing environments on marine aerosol emissions (focusing in particular on polar regions) strongly regulating our changing climate.
