Using Global-Scale Earth System Models for Regional Fisheries Applications

Climate change may impact ocean ecosystems through a number of mechanisms, including shifts in primary productivity or plankton community structure, acidification, and deoxygenation. These processes can be simulated with global Earth system models (ESMs), which are increasingly being used the context fisheries management other living marine resource (LMR) applications. However, projections LMR-relevant metrics such as net production vary widely between ESMs, even under identical climate scenarios. Therefore, use ESM should accompanied by an understanding structural differences biogeochemical sub-models within ESMs that give rise to these differences. This review article provides brief overview some most prominent among recent generation how they relevant LMR application.
