Climate-active trace gases: How air-sea interactions influence their production, consumption, and cycling between the atmosphere and ocean

.

Session 25 - IGAC-SOLAS: Chemistry and physics at surface ocean and lower atmosphere

Air-sea interactions take center stage in my working group. We currently investigate how the sea surface microlayer influences the transfer of climate-active trace gases between air and sea, how gaseous and liquid pollutants influence climate-active trace gas cycling in the surface ocean, and the mechanisms that drive air-sea gas transfer. Our research uses a variety of methods, including eddy covariance direct flux measurements of carbon dioxide and dimethylsulfide, incubation experiments, discrete seawater analysis using gas chromatography – mass spectrometry, and continuous air and seawater measurements using atmospheric pressure chemical ionization mass spectrometry. In my talk, I will present the current state of our research and provide a glimpse into what I think the future holds. I will highlight how this research ties into the SOLAS community, and provide an overview of the next decade of SOLAS science.
