| Session Description | The global biogeochemical cycle, being an essential component of the Earth’s climate system, links the movement of the biotic and abiotic components between the atmosphere, oceans, land, and lithosphere. The functioning of the global biogeochemical cycle plays a crucial role in shaping the chemical and biological properties of the Earth system. This session seeks contributions to the understanding of the global biogeochemical cycle and its interaction with other components of the Earth system from a modeling perspective. Topics of interest include, but are not limited to, cycling of carbon, nitrogen, oxygen, and other biogeochemical elements and their isotopes of the ocean, terrestrial biosphere, and the interactions between them; biogeochemical control of the sources and sinks of major greenhouse gases such as CO2, CH4, and N2O; effect of human activities (e.g., land use changes, burning of fossil fuels, nitrogen deposition) and climate change , past, present, and future evolutions of the global biogeochemical cycle and underlying processes. Modeling and combined observational/modeling studies of the above and other relevant topics at the local, regional, and global scales are solicited. |
