Regeneration of macronutrients and trace metals during phytoplankton decay: An experimental study

Macronutrients and trace metals are incorporated into phytoplankton during growth and regenerated back into the water column when phytoplankton decay, a process that contributes to the distributions of dissolved trace metals and macronutrients in depth profiles. To study this, we incubated mixed Gulf of Mexico phytoplankton assemblages and monocultures of the diatom Pseudo‐nitzschia dolorosa and the dinoflagellate Karenia brevis in the dark....
