This study shows that vitamin B12, not iron, is the primary limiting nutrient for phytoplankton in the Southern Ocean, with implications for community composition and function.

The paper identifies genomic features of domoic acid biosynthesis in Pseudo-nitzschia diatoms, revealing expanded toxigenic diversity and environmental expression patterns.

The paper uses genomic and hydrographic data to show that ocean circulation structures microbial diversity and function in the South Pacific.
