Ocean ecosystems and living marine resources are now facing many threats from changing climate such as ocean warming, deoxygenation, and acidification. Reliable prediction of marine ecosystems could enable communities to adapt to climate fluctuations and contribute to long-term ecosystem resilience. Global Earth System Models (ESMs), the most complex models of Earth’s interrelated system, are vital tools to understand and predict Earth’s interacting physical-biogeochemical system. Thus, several climate modeling groups nowadays have started to incorporate biogeochemical processes into their physically-based climate models, i.e., ESMs. However, efforts to extend current physical climate predictions to global marine biogeochemistry predictions using ESMs have been hampered by uncertainties in the model and difficulties in biogeochemical initialization procedures.
By tackling these challenges, our lab develops ESM-based marine biogeochemical prediction system and investigates prediction skill of global marine biogeochemistry across various spatial and temporal scales.
