Contributions are invited to the Session OS3.1/BG9.69: “Ocean biogeochemistry: novel approaches and synthesis” at the next EGU General Assembly 2017 (EGU2017), 23–28 Apr 2017, Vienna, Austria.
The cycling of carbon, oxygen, and nitrogen in the world's oceans is undergoing unprecedented change as a result of anthropogenic pressures. Observations and future projections at all spatio-temporal scales of the complex interactions within these biogeochemical cycles and their perturbations will help us to understand the implications of future changes for marine ecosystems and ocean sustainability. This session will bring together researchers that use a range of novel techniques, including observations, experiments, models and remote sensing, as well as global data sets to further our understanding of the biological carbon-pump, the biogeochemical cycles in the ocean and their connections to ecosystems and climate. Contributions dealing with the cycling of carbon, oxygen, and nitrogen in the ocean, dissolved and particulate stoichiometry and elemental ratios, ocean acidification, exchange processes at the air-sea interface, role of sea-ice in global biogeochemical cycles and synthesis studies including those using global data sets such as SOCAT and GLODAP are welcomed.
