This dataset contains ocean and ocean biogeochemistry outputs (NetCDF files) from modeling experiments with realistic Cenomano-Turonian paleogeography and various set of idealized Earth' orbit confiurations (Eccentricity, Obliquity, Precession) . The set of simulation targets the ocean oxygenation response to variation in orbital parameters (Sarr et al. 2022) . The simulations have been run using the IPSL-CM5A2 General Circulation Model (Sepulchre et al. 2020 - IPSL-CM5A2 – an Earth system model designed for multi-millennial climate simulations, GMD) and offline version of PISCESv2 model (Aumont et al., 2015 - PISCES-v2: an ocean biogeochemical model for carbon and ecosystem studies, GMD). It includes 6 ocean-atmosphere simulations and 6 ocean biogeochemistry simulations. Data are monthly averages over the last 100 years of the simulations.
