Med Modeling

A team of Italian climate modelers has been evaluating the performance of a new version of the Regional Earth System Model (RegCM-ES) over the Mediterranean region. The model uses MITgcm for its ocean component.

Blooming Antarctica

Researchers use MITgcm to understand how phytoplankton blooms and inorganic carbon respond to sea-ice variability in the West Antarctic Peninsula.

Exploring Zooplankton Dynamics in the Gulf of Mexico

FSU graduate student Taylor Shropshire has been using MITgcm to explore zooplankton dynamics in the Gulf of Mexico.

Shelf Life

This month we focus on work led by Hajoon Song, a postdoc at MIT, who has been using MITgcm to explore nutrient sources for the Patagonia Shelf Region.

Probing Phytoplankton in the Agulhas

This month we report on researchers using MITgcm to explore the role of Agulhas Rings in plankton transport observations from the Tara Oceans Expedition.

Ocean Biology Meets Physics

In this video, Mick Follows describes his group’s work using MITgcm and ECCO2 products to better understand the global carbon cycle and plankton populations.

Anthropogenic CO2 transport in the Southern Ocean.

In and out: Driven by winds, the Southern Ocean's currents (blue globe) transport CO2 (red) northward. Credit: T. Ito et al., Nature 463 (2010)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

Multiple-Resource Experiment. (top) Emergent biogeographical provinces, defined by most dominant species, reminiscent of Longhurst (1995)
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…

Lake Modeling

Figure 1. Summer-time, mean circulation. The plot shows depth integrated current (arrows) overlying column average water temperature (colored). Arrows illustrating vector flow are plotted every 5 grid-points.

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…

Ocean Ecosystems

Figure 1. Illustration of the key components in the self-assembling phytoplankton community model. After some years of interaction, the fittest "types" persist and occupy distinct habitats.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…
