Monitoring natural variations in microbial diversity is crucial because microorganisms play a major role in the environmental processes in marine sediment. To evaluate the microbial diversity in Yeosu Bay sediment, 16S rRNA gene amplicon sequencing was performed. , , and were the predominant phyla in all sediment samples observed.

A comprehensive review of scholarly articles was conducted to examine the marine environmental changes in four representative bays in Korea. Cheonsu Bay experienced a reduction in water area to half of its original size due to the completion of dikes and related reclamation projects. Consequently, the flow environment and biota were altered, leading to increased organic pollution.

The brackish water clam (Corbicula japonica) is constantly exposed to stressful salinity gradients and high levels of heavy metals in the freshwater-saltwater interface of estuary environments, which are introduced from upstream regions and land. To identify the key molecular pathways involved in the response to salinity changes and heavy metal bioaccumulation, we obtained the transcriptomes of C. japonica inhabiting different salinities and heavy metal distributions in Gwangyang Bay (Korea) using RNA sequencing.

The spatiotemporal distribution of MASTs (MArine STramenopiles), mostly affiliated with heterotrophic protists, and their interactions with Synechococcales were investigated in an anthropogenically polluted bay of the East Sea using 18S rRNA and 16S rRNA gene sequences. The bay was characterized by strong stratification between the surface and bottom layers and cold and nutrient-rich water intrusion in summer, whereas the bay water was well mixed in winter. MAST-3, MAST-6, MAST-7, and MAST-9 were the major MAST clades, whereas the dominance of MAST-9 declined from >80 % in summer to <10 % in winter and the diversity of MAST communities increased in winter.
