MESMO global model output for glacial simulations with dynamic C:N:P ratios

Abstract:

Model outputs archived have a complete suite of biogeochemical state variables in the 3D global ocean domain. They 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. After 5000 years, almost all properties reach steady state, with the except nitrogen fixation and denitrification in some runs

Description

The ocean model used to generate these outputs is MESMO (Matsumoto et al., 2008, 2013). 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 experiments under the modern conditions and under glacial conditions. These experiments are described and their results analyzed in a submitted manuscript: Matsumoto, Rickaby, and Tanioka, "Carbon export buffering and CO2 drawdown by flexible phytoplankton C:N:P under glacial conditions." The experiments are all 5000 year runs.
