Title：New Insights into Microbial Roles in Deep-Sea Cold Seep Geochemical Cycles

Abstract：This talk examines deep-sea cold seeps as critical biogeochemical hotspots, emphasizing microbial roles in carbon, nitrogen, and phosphorus cycling. Recent findings reveal dehalogenation as a core process and significant nitrogen transformation, alongside a microbial-virus "arms race" that supports ecosystem stability. These insights advance understanding of global biogeochemical cycles and climate impacts.

Speaker：Dr. Felix J. Elling, Christian-Albrecht University of Kiel

Title: Interpreting the geologic record of life and climate through the lens of microbial ecology

Abstract：Lipid biomarkers produced by marine microbes can be preserved for millions of years in sedimentary rocks. Interpreting this record of past life requires a thorough understanding of microbial ecology. In this talk I will highlight how studying modern microbial ecology enables a comprehensive understanding of changes in past climate and ocean biogeochemistry.
