The emergence of ocean biogeochemical provinces: A quantitative assessment and a diagnostic for model evaluation

摘要: [1] The concept of ocean biogeochemical provinces is based on the observation that large regions are characterized by coherent physical forcing and environmental conditions, which eventually representative macroscale ecosystems. Biogeochemical models global focus simulating coupling between prevalent conditions processes with assumption biological properties respond coherently to physics therefore should produce such as an emergent property. In this paper, we quantitatively assess emergence a reference set predefined in available data sets propose province-based approach evaluation one most comprehensive biogeochemistry. Multivariate statistical tools were applied model data, verifying existence, distinctiveness reliability quantifying correlation results observations at scale. The analysis similarity shows they statistically separable output can be used reliable metrics. analyses indicate more easily distinguished terms their features rather than using chlorophyll concentration. characterization means values significant overlap both Sea-viewing Wide Field-of-view Sensor (SeaWiFS) model. It likely related choice province boundaries coarse-resolution mapped not necessarily same those derivable from high-resolution satellite data. We also demonstrated through cluster long-term time series collected Joint Global Ocean Flux Study (JGOFS) stations respective thus evaluate extracted province. method promise for helping overcome problems verification due under sampling variables but gives indications unsupervised clustering may required when spatially resolved available.
