Zinc biogeochemical cycle in the Tasman Sea : potential role for phytoplankton communities ...
Zinc (Zn) plays an essential role in metabolic and structural functions for marine phytoplankton, being required in nearly 300 enzymes and proteins including carbonic anhydrase and alkaline phosphatase. The concentration of total dissolved Zn in the open-ocean is typically in the nanomolar (0.1-10 n...
