We are seeking a scientist to study the extent to which our understanding of the biological carbon pump is consistent with global distributions of inorganic nutrients. You will do this by using the Matrix Free Newton Krylov technique to run a suite of global biogeochemical models. This post is funded by the NERC BATMAN project which will itself contribute to the NERC Process Based Model Evaluation Programme and the NERC Earth System Model strategy. You will work with collaborators within NOC, broader UK and internationally. You will write scientific papers and present findings at project workshops and international scientific conferences.
