This study shows zinc limitation of phytoplankton in Antarctic waters, demonstrating its role in regulating net primary production and providing evidence for the Zn hypothesis.

The paper uses metatranscriptomic and metaproteomic analysis of plankton biomass collected across a 1,050 km transect in the western North Atlantic Ocean to reveal shifts in microeukaryote community composition and metabolic function across depth and environmental gradients.
