Ocean-emitted dimethyl sulfide (DMS) is a major source of climate-cooling aerosols. However, most of the marine biogenic sulfur cycling is not routed to DMS but to methanethiol (MeSH), another volatile whose reactivity has hitherto hampered measurements. Therefore, the global emissions and climate impact of MeSH remain unexplored.

- Reactive trace gas emissions like benzene and toluene from polar oceans impact atmospheric chemistry and climate, yet they are not well-studied.
- Measurements in the Southern Ocean and Arctic suggest these gases have a marine biogenic source, with calculated emission fluxes.
- Incorporating these emissions into climate models showed a significant increase in secondary organic aerosol concentrations, especially in the Southern Ocean, highlighting the need to address these emissions in climate assessments.
The flux of CO between the atmosphere and the ocean is often estimated as the air-sea gas concentration difference multiplied by the gas transfer velocity (K). The first order driver for K over the ocean is wind through its influence on near surface hydrodynamics. However, field observations have shown substantial variability in the wind speed dependencies of K.
