The 36 simulations represent a factorial experimental set-up, where 6 different parameterisations of ocean biology were broadcast across six different physical states. The aim of these experiments was to test if new insights into how the cycling of organic matter in the ocean functions can offer some benefit to climate models. But to be sure that a particular process is important to global ocean biogeochemistry (i.e carbon storage), we needed to make these tests across a range of different circulations and physical states. All physical states were of Pre-Industrial (PI; 1850 CE) climate. They were generated by forcing the Ocean GCM with the boundary conditions produced by piControl runs of CSIRO Mk3L v1.2, GFDL-ESM2G, IPSL-CM5A-MR, HadGEM2-CC, MPI-ESM-MR and MRI-CGCM3. These boundary conditions were sea surface temperature, salinity and the meridional and zonal components of surface wind stresses, and the final 10 years of these runs were averaged and regridded onto the CSIRO Mk3L v1.2 grid space. Therefore, six unique physical ocean states were generated. Six unique biological states were also generated by implementing different biological parameterisations within the biogeochemical model code. These included variable nutrient dependence for phytoplankton growth (Smith et al., 2009), variable remineralisation profiles with depth that were dependent on temperature (Marsay et al., 2015) or community composition (Weber et al., 2016), and a variable stoichiometry of organic matter based on nutrient concentrations (Galbratih and Martiny, 2015). These four different and already published parameterisations were implemented into the biogeochemical code individually, and once in combination (excluding the temperature-dependent remineralisation), to create five new biogeochemical models. Hence, six unique biological states were created, including the basic, unaltered biogeochemical model. Climatologies of sea surface temperature, sea surface salinity, and x and y vectors of sea surface wind stresses were produced by both the PI and LGM coupled experiments and were used to force the ocean general circulation model. Additional climatologies of sea ice fractional cover, sea surface wind speeds, net incident short-wave radiation, and the aeolian deposition of iron and reactive nitrogen were important for forcing the biogeochemical model. These climatologies are made available here. Also available are the three-dimensional global annual averages of oceanic properties for all 36 simulations at their steady-state solutions. These include temperature, salinity, oxygen, apparent oxygen utilisation, dissolved inorganic carbon, alkalinity, phosphate, nitrate and iron concentrations.

(2018) Dynamic biological functioning important for simulating and stabilising ocean biogeochemistry. Global Biogeochemical Cycles. Provided Keywords: ocean biogeochemistry, paleoclimatology, Pleistocene, CO2, biological pump ABSTRACT SUPPLIED BY ORIGINATOR: The biogeochemistry of the ocean exerts a strong influence on the climate by modulating atmospheric greenhouse gases. In turn, ocean biogeochemistry depends on numerous physical and biological processes that change over space and time. Accurately simulating these processes is fundamental for accurately simulating the ocean's role within the climate. However, our simulation of these processes is often simplistic, despite a growing understanding of underlying biological dynamics. Here we explore how new parameterisations of biological processes affect simulated biogeochemical properties in a global ocean model. We combine 6 different physical realisations with 6 different biogeochemical parameterisations (36 unique ocean states). The biogeochemical parameterisations, all previously published, aim to more accurately represent the response of ocean biology to changing physical conditions. We make three major findings. First, oxygen, carbon, alkalinity and phosphate fields are more sensitive to changes in the ocean's physical state. Only nitrate is more sensitive to changes in biological processes, and we suggest that assessment protocols for ocean biogeochemical models formally include the marine nitrogen cycle to constrain biological processes. Second, we show that dynamic variations in the production, remineralisation and stoichiometry of organic matter in response to changing environmental conditions benefits the simulation of ocean biogeochemistry. Third, dynamic biological functioning reduces the sensitivity of biogeochemical properties to physical change. Carbon and nitrogen inventories were 50 % and 20 % less sensitive to physical changes, respectively, in simulations that incorporated dynamic biological functioning. These results highlight the importance of a dynamic biology for ocean properties and climate.
