a Sampling site map, including the East China Sea, Indian Ocean, and coastal city (Qingdao, China), with an enlarged view showing the sampling points in the East China Sea. S01-1, S01-2, and S01-4 are three sampling locations in the East China Sea with different distances to the continent. The global map was created using the ArcGIS Pro 3.0.2 software, and the coastline data were obtained from the Global Self-consistent, Hierarchical, High-resolution Geography Database (GSHHG; https://www.soest.hawaii.edu/pwessel/gshhg/). b Fraction of OSs in total organic compounds in seawater, marine aerosols, and sea spray aerosol (SSA), shown in green and yellow for marine aerosols and SSA, respectively. Error bars represent the standard deviation (SD). BDL means “below the detection limit”. c The OS composition in field marine aerosol and laboratory SSA is shown as the doughnut plots. C12H26O4S, one of the most abundant OS species in particulate matter samples from the East China Sea and Indian Ocean, is highlighted in red.
