When the Wind Blows Harder

Andreas Klocker, an oceanographer working at the University of Tasmania, has been using MITgcm to explore the sensitivity of ventilation to surface wind stress in the Southern Ocean.


Exploring the Southern Ocean pCO2 Wind Stress Connection

This month we spotlight work from UK researchers led by Ben Bronselaer (formerly of Oxford, now at Princeton) who have been using MITgcm to understand the feedback between mixed-layer partial pressure of carbon dioxide pCO2 and wind stress in the Southern Ocean.


Melting Antarctica

This month we spotlight work by Alberto C. Naveira Garabato. Garabato and his team have been running idealized modelling experiments using MITgcm to study the immediate behavior of meltwater as it ascends from an ice shelf cavity.


Summing Up Southern Ocean Upwelling

This month we spotlight work using MITgcm to better understand how upwelling associated with the Antarctic Circumpolar Current connects with atmospheric CO2 concentrations.


Wind Blown

In a new study, researchers from Scripps have been using MITgcm to evaluate the role form stress across bottom topography plays in balancing the input of stress by wind at the surface.


Slip Sliding Away…

Under the Ice

In a new paper published in the Annals of Glaciology, long-time MITgcm users Patrick Heimbach and Martic Losch investigate the sensitivity of sub-ice-shelf melt rates under the Pine Island Ice Shelf, West Antarctica, to changes in the oceanic state.


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…
