Marine ecosystem prediction with a global ESM and its potential utility for marine resource management


Earth system models (ESMs) are vital tools to understand and predict Earth’s interacting physical-biogeochemical system. Efforts to extend current physical climate predictions to globalmarine biogeochemistry predictions using ESMs, however, have been hampered by uncertainties in the model and initialization procedures. Inthis study, by developing an ESM-based marine biogeochemistry prediction system with an operational climate data assimilation scheme, we investigate the seasonal to multi-annual prediction skill of global marine biogeochemistry. The initial assessment of biogeochemical predictions is successful, showing skillful chlorophyll predictions in many ocean basins. Further investigations of the utility of biogeochemical predictions show that annual fish catches in large coastal ecosystems are significantly predictable up to 1-2 year in advance, suggesting a role for ESM-based marine biogeochemical predictions in dynamic marine resource management efforts.
