| Summary: | Atmospheric CO2 reconstructions beyond ice core records are based on geochemical proxies, which bear proxy-specific intrinsic uncertainties. Here, we use the global carbon cycle box model BICYCLE-SE and explore possible changes in the carbon cycle during the last 4 Myr in order to improve existing interpretation of proxy-based CO2 reconstructions with focus on δ11B. Simulating the full marine carbon cycle the results can be compared with various variables of interest, and which are necessary within the context of the δ11B-based CO2 proxy. In detail, these are pH, dissolved inorganic carbon, total alkalinity, and pCO2 within the surface equatorial Atlantic or equatorial Pacific, the areas in which the sediment records are located, that are used for atmospheric CO2 reconstructions.In addition, simulated mean ocean δ13C is compared with various available data.The model is forced with changing physical boundary conditions, mainly changes in temperature and sea level, which are taken from a new data compilation. ... : Archive file (tgz) which includes besides a README:14 data files (ASCII), including headers explaining the dataBrief file description:Simulation results:- BICYCLE-SE_all_forcing_5ma_withheader.dat Important forcing time series for the BICYCLE-SE model- BICYCLE-SE_18scenariosatmCO25Ma_withheader.dat Simulated atmospheric CO2 concentration using the BICYCLE-SE model for 18 different scenarios- BICYCLE-SE_18scenariosod13C5Ma_withheader.dat Simulated mean ocean ????13C using the BICYCLE-SE model for 18 different scenarios- BICYCLE-SE_4scenariosAtl_CO35Ma_withheader.dat Simulated CO3 in the Atlantic (surface and deep) using the BICYCLE-SE model for 4 different scenarios- BICYCLE-SE_4scenariosIPac_CO35Ma_withheader.dat Simulated CO3 in the Indo-Pacific (surface and deep) using the BICYCLE-SE model for 4 different scenarios- BICYCLE-SE_4scenariosAtl_IPac_CSH5Ma_withheader.dat Simulated Calcite Saturation Horizont (CSH) in the Atlantic and Indo-Pacific using the BICYCLE-SE model for 4 different scenarios- ... |
