Marine biogeochemical cycles and pelagic sediments

Together with the RECORDER, the influence of our new ocean-floor element fluxes on the global biogeochemical cycles will be studied using the cGENIE Earth-system model (Ridgwell and Schmidt, 2010), which will include the two-way interaction between seawater and pelagic sediments and be forced by changes in weathering and sea level. This Earth-system model will be employed to estimate global budgets using methods that make optimal usage of the diverse observations and reconstructions, including new time series of carbonate chemistry and ocean saturation from the Recorder (Pälike et al., 2012).
