Atmospheric iron supply and marine productivity in the ...

Iron Fe is a key element in the Earth climate system, as it can enhance marine primary productivity in the high-nutrient low-chlorophyll HNLC regions where, despite a high concentration of major nutrients, chlorophyll production is low due to iron limitation. Eolian mineral dust represents one of the main Fe sources to the oceans; thus ...

What are Phytoplankton? - NASA

Derived from the Greek words phyto plant and plankton made to wander or drift , phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.. Some phytoplankton are bacteria, some are protists, and most are single-celled plants. Among the common kinds are cyanobacteria, silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.
