Serendipitous discovery of a large preindustrial, north-to-south interhemispheric ocean transport

Serendipitous discovery of a large pre-industrial, north-to-south inter-hemispheric ocean transport (~0.8 Pg C yr-1) due to iron limited primary productivity in the Southern Ocean. This finding resolves a long-standing enigma as to why all other ocean models (none of which featured iron limitation) could not simulate such a large inter-hemispheiric ocean transport, as theorized based on supposed pre-industrial atmospheric CO2 gradients. For instance, this was studied and reported on extensively in the EU GOSAC project (part of OCMIP-2). These new NOCES results are described in detail in the NOCES-funded Ph.D. thesis of Patrick Wetzel (MPIM, Partner 6): Wetzel [2004] Inter-annual and decadal variability in the air-sea exchange of CO2 a model study, Ph.D. thesis, University of Hamburg, MPIM, Germany.
