Anthropogenic CO2 transport in the Southern Ocean.
Taka Ito, Molly Woloszyn and Matt Mazloff have been studying anthropogenic CO2 transport in the Southern Ocean. Using MITgcm’s adjoint and offline capabilities, the team find a clear correlation between the pattern of carbon uptake and oceanic vertical exchange in strong support of wind-driven primary regulation of Southern Ocean ACO2 transport…
Ecological Control of Subtropical Nutrient Concentrations
In this article we spotlight recent work by Darwin Project team members Stephanie Dutkiewicz, Mick Follows and Jason Bragg, who have been examining the utility of resource control theory to interpret the relationships between organisms and resources in a global coupled physical-biogeochemistry-ecosystem model built around MITgcm…
Overturning Sensitivity in an Eddying Ocean Model
Work by Christopher Wolfe and Paola Cessi at UCSD, in which they investigate the equilibrium response of an eddy-resolving version of MITgcm to variations in the external parameters of diffusivity, wind forcing and geometry, with particular attention to the meridional overturning circulation (MOC) and deep stratification…
Planet-in-a-Bottle
Work by Sai Ravela, John Marshall, Chris Hill, Andrew Wong and Scott Stransky in which they use MITgcm to provide the virtual analogue for a fluid lab experiment in the physical laboratory. This is part of an effort to demonstrate how to achieve real-time model-data synthesis, using measurements from a roboticaly controlled automated sensor system…
Tidal Mixing Over Rough Topography
Work by Maxim Nikurshin and Sonya Legg at GFDL using a 2d version of MITgcm to explore radiation and dissipation of the internal tides generated through tidal mixing over rough topography…
Ocean Ecosystems
Work by Fanny Monteiro with Mick Follows and Stephanie Dutkiewicz at MIT who have been using the MITgcm to probe the behaviour of self-assembling phytoplankton communities within a global ocean circulation…
PRM
Work by Jean-Michel Campin, Chris Hill, Helen Jones and John Marshall at MIT using the MITgcm to exploit a multi scale superparameterization approach to increase efficiency in modeling oceanic deep convection (ODC)…
Adjoint Advances
Adjoint Advances story by Helen Hill Two MITgcm adjoint activities are (i) the development of an open-source, extensible automatic differentiation tool, OpenAD and (ii) the configuration of an ~18km resolution global ocean and sea-ice experiment as part of the ECCO2 project.
