  abstract = {{D}iatoms sustain the marine food web and contribute to the export of carbon from the surface ocean to depth. {T}hey account for about 40% of marine primary productivity and particulate carbon exported to depth as part of the biological pump. {D}iatoms have long been known to be abundant in turbulent, nutrient-rich waters, but observations and simulations indicate that they are dominant also in meso- and submesoscale structures such as fronts and filaments, and in the deep chlorophyll maximum. {D}iatoms vary widely in size, morphology and elemental composition, all of which control the quality, quantity and sinking speed of biogenic matter to depth. {I}n particular, their silica shells provide ballast to marine snow and faecal pellets, and can help transport carbon to both the mesopelagic layer and deep ocean. {H}erein we show that the extent to which diatoms contribute to the export of carbon varies by diatom type, with carbon transfer modulated by the {S}i/{C} ratio of diatom cells, the thickness of the shells and their life strategies; for instance, the tendency to form aggregates or resting spores. {M}odel simulations project a decline in the contribution of diatoms to primary production everywhere outside of the {S}outhern {O}cean. {W}e argue that we need to understand changes in diatom diversity, life cycle and plankton interactions in a warmer and more acidic ocean in much more detail to fully assess any changes in their contribution to the biological pump.},
