A recent paper, published in Global Biogeochemical Cycles, highlighting new observations from robotic profiling floats demonstrates that areas of high carbon export in the Southern Ocean are actually associated with very low concentrations of iron, an important micronutrient for supporting phytoplankton growth. This suggests a decoupling between the production and export of organic carbon in this region. The study was led by AOS Associate Research Scholar Lionel Arteaga and is currently featured on the Ocean Carbon & Biogeochemistry (OCB) website.
