"Nutrients and Toxic Signals: The Role of Phytoplankton in Cryptic Biogeochemical Cycles"

Microorganisms control the geochemistry of our planet via metabolic pathways that link the global cycles of key elements, such as carbon, nitrogen, phosphorus, oxygen, and metals. However, many biogeochemical transformations are cryptic. Cryptic biogeochemistry involves a chemical species with an exceedingly low residence time, typically driven by high rates of reactive consumption.
