In the Southern Ocean, phytoplankton must cope with harsh environmental conditions such as low light and growth limiting concentrations of the micronutrient iron. We collected 25 surface seawater samples from the western Antarctic Peninsula (WAP) and assessed the influence of oceanographic variables...

In the Southern Ocean, phytoplankton must cope with harsh environmental conditions such as low light and growth limiting concentrations of the micronutrient iron. We collected 25 surface seawater samples from the western Antarctic Peninsula (WAP) and assessed the influence of oceanographic variables on the diversity of the phytoplankton community composition and on the metabolic strategies of diatoms by performing metatranscriptomics. We found that cross-shelf differences in oceanographic parameters such as temperature and variable nutrient concentrations account for most of the differences in phytoplankton community composition and metabolism. We opportunistically characterized the metabolic underpinnings of a large bloom of the centric diatom Actinocyclus in coastal waters of the WAP.
