Biogeochemistry
Scope
Biogeochemistry is an interdisciplinary study field including ecology, geochemistry, oceanography, limnology, hydrology, soil science and Environmental sciences. However, researches tended to be conducted separately so far. This session aims to provide a common platform for biogeochemists of different disciplines, which facilitates the interactive discussion and information exchanges for further development of biogeochemical studies. Various biological activities on the earth have great impacts on changes and evolution of the surface environment. In this session, spatial and temporal biogeochemical cycles of inorganic elements as well as organic compounds will be discussed for comprehensive understanding of the environmental changes and evolution of biosphere.
