Welcome to the Southern Ocean pages at the University of Arizona!

The Southern Ocean accounts for half the ocean’s uptake of anthropogenic carbon from the atmosphere and the majority of its uptake of heat. Models indicate that upwelling in the Southern Ocean delivers nutrients to lower latitude surface waters that are critical to ocean ecosystems around the world. The impacts of ocean acidification from rising CO2 are projected to be most severe in the Southern Ocean, with ecosystem tipping points being reached in a few decades.

In order to promote and make accessible the latest research regarding the Southern Ocean, this site has two main components:

  • The Southern Ocean Model Intercomparison Project (SOMIP):
  • The Southern Ocean Climate Model Atlas (SOCMA)

Both of these endeavors are funded, in part, through the Southern Ocean Carbon and Climate Observations and Modeling project (SOCCOM).

This work is a product of the UA Biogeochemical Dynamics Laboratory (BGDL), led by Prof. Joellen Russell, the Thomas R. Brown Distinguished Chair of Integrative Science.
