Iron is an essential micronutrient for marine phytoplankton. In large areas of the ocean, it regulates the marine productivity and hence the ocean carbon cycle. Iron availability is both influenced by and influences climate change. While we are slowly obtaining a picture of the present global distribution of dissolved iron in the ocean (particularly with the advent of GEOTRACES program), there is still no consensus on the mechanisms behind this distribution.
The first part of my talk briefly illustrates the importance of having an iron model in numerical models of ocean biogeochemistry which aim at making projections of climate change and its impact on marine ecosystems. The second part of the talk explains how the iron modelling started and has further developed, how complex and different the models are and how well they compare to the ‘real’ world. In the last part of the talk, I like to give a short introduction of some details of our model (REcoM) and processes focused in our ongoing studies.
