MESMO global ocean model results for glacial and freshwater hosing simulations with calibrated, semilabile and refractory dissolved organic matter (DOM). The dataset contains NetCDF files with 3D ocean biogeochemistry model outputs.
The ocean model used to generate these outputs is MESMO 3 (Matsumoto et al., 2021). Briefly, it is an earth system model of intermediate complexity that consists of a 3D dynamical model of the global ocean, 2D dynamic-thermodynamic model of sea ice, and 2D energy moisture balanced model of atmosphere. The results archived here are from MESMO 3 experiments under the modern conditions with freshwater hosing and under glacial conditions. The "c" in the dataset name "MESMO 3c DOM" indicates the calibrated version of MESMO 3 was used. These experiments are described and their results analyzed in a submitted manuscript: "Modeling marine dissolved organic carbon response to climate change” by Maya D. Gilchrist and Katsumi Matsumoto.
Model outputs archived have a complete suite of biogeochemical state variables in the 3D global ocean domain. The main variables are related to the dissolved organic matter. The complete set of variables include temperature, salinity, nutrients (PO4, NO3, Fe, Si), carbon pools and their isotopes (DIC, DOC, POC, 13C and 14C) oxygen, and alkalinity. Stoichiometric ratios of phytoplankton functional types (C:P, C:N, N:P) are also included. Rates and fluxes archived include production (NPP, export) by phytoplankton types and nitrogen fixation and denitrification.
MESMO 3c model runs with semilabile and refractory DOM. 220407 experiments are transient freshwater hosing experiments. 220408 experiments are steady state glacial model runs.
