Linking the Oceanic Biogeochemistry of Iron and Phosphorus with the Marine Nitrogen Cycle... 

Arguably, phosphorus (P) and iron (Fe) are the two nutrients that most impact the global marine nitrogen (N) cycle. Over the past 15 years a proliferation of new work on Fe limitation has left no doubt that this micronutrient profoundly influences nitrogen biogeochemistry over perhaps the majority of the ocean s surface. Recent work has also brought a renaissance of renewed attention to P limitation, and to its reciprocal interactions with nitrogen.
