Biogeochemistry: Iron findings
Philip W. Boyd1
Abstract
A huge phytoplankton bloom in the Southern Ocean yields estimates of how a continuous supply of iron affects oceanic carbon sequestration. But iron is not the only factor — nutrient supply is crucial too.
The ocean is a daunting place to study, where investigations must contend with a wide range of scales — from intracellular to ocean basins, from nanoseconds to seasons1. The difficulties are evident in the variety of approaches used to study the ecological productivity of its microscopic algae, or phytoplankton.
