Nutrient consumption and chain tuning in diatoms exposed to storm-like turbulence

Abstract Current information on the response of phytoplankton to turbulence is linked to cell size and nutrient availability. Diatoms are considered to be favored by mixing as dissolved nutrients are more easily accessible for non-motile cells. We investigated how diatoms exploit microscale turbulen...
