"Does Iron Limitation Control the Oceans Biological Carbon Pumps?"

Iron is a key micro-nutrient limiting biological productivity in large 
areas of the ocean. It has been hypothesized that changes in the dust-borne 
transport of iron to the remote oceans may have led to the large 
glacial-interglacial changes in atmospheric CO2 recorded in ice cores. We 
will discuss this hypothesis using models of the coupled oceanic cycles of 
iron, phosphate, oxygen and carbon and interpretation of large scale ocean 
surveys.
