The effect of zooplankton on the distributions of dimethyl sulfide and dimethylsulfoniopropionate in the Bohai and Yellow Seas

We aim to study the effect of zooplankton on the distributions of dimethyl sulfide and dimethylsulfoniopropionate in the Bohai and Yellow Seas. Horizontal and vertical distributions of DMSP, DMSP lyase activity, DMS, and the abundances of bacteria, DMSP-consuming bacteria (DCB), DMSO-consuming bacteria and picophytoplankton in the Bohai Sea (BS) and Yellow Sea (YS) were investigated in autumn 2020. Bacterial community composition was conducted in February of 2021.
