Abstract

Iron is an important nutrient in marine biogeochemical cycles because it limits primary production in high-nutrient, low-chlorophyll areas and nitrogen fixation rates in nitrogen-limited areas. Although three-dimensional biogeochemical cycle models were developed in the 1990s to evaluate oceanic carbon dioxide uptake, it was not until 2000 that such models considered iron cycling. This was mainly because of limited field data on iron, arising from difficulties in measuring dissolved iron. Early iron cycle models were developed from knowledge based on limited field data, and such models assumed that global-scale dissolved iron distribution was determined simply by iron supply from aeolian deposition and removal by scavenging via complexation with organic ligands. Subsequent accumulation of field data has revealed that various external sources, cycling of organic ligands, and colloidal aggregation can affect global- and basin-scale distributions of dissolved iron. In this paper, we review the history of the development of marine biogeochemical cycle models with a special focus on iron, and describe their current status and issues that must be addressed for further model improvement. Recent activity regarding the Iron Model Intercomparison Project is also described.
