Abstract Key roles of marine dimethyl sulfoniopropionate (DMSP), sulfide (DMS), methyl mercaptan (MeSH), and carbon disulfide (CS 2 ) in the sulfur cycle and/or atmospheric chemistry, alongside rapid environmental changes ecosystems, underscore need to understand their responses dynamic ecosystem shifts. We conducted two ship‐based incubation experiments Northwest Pacific Eastern Indian Oceans explore how dust deposition, ocean acidification, microplastic exposure impact these compounds. Our results demonstrate that stressors not only alter phytoplankton community but also modify per‐cell DMSP production capacity degradation pathways, subsequently influencing DMSP, DMS, MeSH concentrations. CS 's response closely mirrors abundance species. Initial physical‐chemical conditions, such as carbonate system nutrient availability, may mediate sensitivity compounds This study enhances our understanding biogenic ecosystems provides essential basis for future climate modeling.
