MESMO 3: Flexible phytoplankton stoichiometry and refractory dissolved organic matter
<p>We describe the third version of Minnesota Earth System Model for Ocean biogeochemistry (MESMO 3), an Earth system model of intermediate complexity, with a dynamical ocean, dynamic–thermodynamic sea ice, and an energy–moisture-balanced atmosphere. A major feature of version 3 is the flexibl...

pools of C, N, P, and Fe that can be enabled in MESMO 3 as an optional
feature. The refractory dissolved organic matter can be degraded by
photodegradation at the surface and hydrothermal vent degradation at the
bottom. These improvements provide a basis for using MESMO 3 in further
investigations of the global marine carbon cycle to changes in the
environmental conditions of the past, present, and future.</p> |
