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.

What you Can Do With a Really Rather Realistic Ocean Model

This month we spotlight research from MIT’s Darwin Project exploring how changes in spatial resolution impact emergent biogeochemistry and phytoplankton community structure in their work using MITgcm and the biogeochemical models they have built to surround it.

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.

Mercury Rising

A joint Harvard – MIT study uses MITgcm to explore the biogeochemistry of riverine mercury.

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.

Arctic Carbon Cycle Modeling

Arctic Biogeochemical Model - Change in Surface Net Community Production, year-on-year between 2006 and 2007 using MITgcm. Motivated by observations indicating rapidly falling annual sea-ice minima, Manfredi Manizza and co-workers have been using an Arctic configuration of MITgcm to explore the Arctic Ocean Carbon Cycle.

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…
