Phaeocystis antarctica strain 1374, Phaeocystis antarctica strain 1871, grown in iron concentrations of 0nM, 1nM, 3nM, 10nM, 30nM, and 100nM. Ross Sea Phaeocystis bloom sample.
Iron and light are typically recognized as major limiting factors controlling phytoplankton growth in the Southern Ocean. Recent field-based evidence suggests, however, that manganese concentrations in this region can be low enough to impact phytoplankton physiology and primary productivity. Our stu...
Coastal Antarctic marine ecosystems play an important role in carbon cycling due to their highly productive seasonal phytoplankton blooms. Southern Ocean microbes are primarily limited by light and iron (Fe) and can be co-limited by cobalamin (vitamin B12 ). Micronutrient limitation is a key driver ...
