Abundant microzooplankton possibly cause ultrahigh seawater dimethylsulfide during Southern Ocean algal blooms
Highlights: • Ultrahigh seawater DMS levels (>40 nM) were detected near the Antarctic Peninsula. • Ultrahigh DMS was only found in waters of algal bloom and abundant microzooplankton. • Grazing of abundant microzooplankton possibly cause the ultrahigh seawater DMS. Oceanic dimethylsulfide (DMS) i...
