Nanoplanktonic diatoms are globally overlooked but play a role in spring blooms and carbon export

Abstract Diatoms are one of the major primary producers in the ocean, responsible annually for ~20% of photosynthetically fixed CO 2 on Earth. In oceanic models, they are typically represented as large (>20 µm) microphytoplankton. However, many diatoms belong to the nanophytoplankton (2–20 µm) and a... View More
