By coupling an ecosystem
model to a Pacific Ocean setup of ROMS (the Regional Oceanic Modeling System)
at eddy-permitting resolution and performing experiments in scale ranging from
the patch size of in situ experiments to the
several 100km size of coarse resolution models, we aim to establish a
connection between large-scale global model studies and the many insights
emerging from the very small-scale patch fertilization studies. Our research
will be guided by three hypotheses, which state that the export efficiency of
fertilization, i.e. the amount of carbon that is being exported from the
surface ocean per unit of iron applied to the ocean, will depend critically on
the size and duration of the experiment.
