Ferredoxin and flavodoxin as indicators of iron availability in Antarctic sea ice microalgal communities ...
The availability of the micronutrient iron is known to exert control on phytoplankton growth and community composition in much of the Southern Ocean. The role of this trace element in regulating primary production in Antarctic pack ice is however, largely unknown. To investigate the availability of...

The availability of the micronutrient iron is known to exert control on phytoplankton growth and community composition in much of the Southern Ocean.
