OCCA
This month we focus on work by Gael Forget and the ECCO team who have been using MITgcm to construct a new ocean atlas. By using MITgcm as a means of optimally synthesising data within the framework of a physically accurate general circulation model, OCCA (short for OCean Comprehensible Atlas) provides a singularly accurate 3-year “snap-shot” of the global ocean state for the period December 2003 to November 2006…
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…
2009 research roundup
To round off the year we have collected a sample of 2009 research articles that involved MITgcm in some way. Lots of interesting work ranging from gas-giant planets to laboratory scale rotating fluid tanks. Take a look…
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…
Lake Modeling
Work by Galen McKinley and Val Bennington at the University of Wisconsin, Madison using MITgcm to model the general circulation of Lake Superior as part of a project to develop a quantitative understanding of the role such bodies of water may play in the terrestrial carbon cycle…
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…
ConGRADulations!
Congratulations to MITgcm’s two newest doctoral graduates:Fanny Monteiro and Maxim Nikurashin.
