With global climate change and the deterioration of the marine environment, the biogeochemical processes of the main biogenic elements in the ocean have received considerable attention. The spatiotemporal distribution patterns, migration and transformation processes of marine biogenic elements, as well as the responses to environmental factors such as global warming, atmospheric sedimentation, eutrophication, ocean acidification, and hypoxia, have attracted widespread attention. Microorganisms are the main drivers of the biogenic factor cycle. Climate change and the deterioration of the marine environment have profoundly affected the structure and function of microbial communities, leading to changes in the biogenic factor cycle mediated by microorganisms, and changing the position and role of the oceans in the global biogenic factor cycle and climate change.

Biogenic elements determine the marine biogeochemistry cycling but are disturbed by environmental factors such as global warming, atmospheric sedimentation, eutrophication, ocean acidification, and hypoxia. However, responses of biogenic elements to these disturbances and their corresponding microbial transformations were still under debate. Such a situation highlights the need to study biogenic elements better by incorporating physical, biological and chemical perspectives.

The focus of this Research Topic is on studies that use physical, biological and chemical methods to explore how biogenic elements respond to environmental change. It calls for original and novel papers related to responses of biogenic elements in any of the following research topics:

• The impacts of global climate changes on spatiotemporal distribution patterns, migration and transformation processes of marine biogenic elements.

• The role of microorganisms on the biogenic elements’ transformations in a marine ecosystem.

• The responses of the microbial community to global changes in a marine ecosystem.

• The interactions between biogenic elements and microorganisms facing global climate changes.
