5. Black-box methods may give high r 2 but they do not increase our understanding of the system. Mechanistic models, even if they perform less well in predicting, have the benefit of increased knowledge of system functioning.

6. ２．なぜモデルが必要か？ 実測不能なプロセスの定量評価 知りたいことー モデル ー実測可能なデータ At great water depths, sediment organisms feed on organic particles raining down from the upper water layers. The more food available, the more organisms survive and the higher the total biomass. But how can we measure the amount of food deposition? Using micro-electrodes, mounted on sophisticated landers, biogeochemists measure high-resolution profiles of oxygen concentration as a function of sediment depth. Fitting these oxygen profiles with a model estimates oxygen fluxes, from which organic matter deposition rates are calculated.
