遥感在制定海洋中上层生态系统指标方面具有许多优势。在这方面特别合适的是可以从遥感数据构建的时间序列产生的指标。例如，使用海洋颜色辐射测量法，可以评估浮游植物华的物候。以这种方式定义的指标有望成为整个远洋生态系统的信息指标。一个简单的浮游植物-基质模式，其强迫依赖于纬度和日数，用于探索水华物候的定性特征，以便与从西北大西洋遥感评估的一套10年叶绿素浓度时间序列中观察到的结果进行比较。该模型揭示了在评估观测数据时可能被忽视的动力学特征。(C) 2008 Elsevier B.V.版权所有
Remote sensing offers many advantages in the development of ecosystem indicators for the pelagic zone of the ocean. Particularly suitable in this context are the indicators arising from time series that can be constructed from remotely sensed data. For example, using ocean-colour radiometry, the phenology of phytoplankton blooms can be assessed. Metrics defined in this way show promise as informative indicators for the entire pelagic ecosystem. A simple phytoplankton-substrate model, with forcing dependent on latitude and day number is used to explore the qualitative features of bloom phenology for comparison with the results observed in a suite of 10-year time series of chlorophyll concentration, as assessed by remote sensing, from the Northwest Atlantic Ocean. The model reveals features of the dynamics that might otherwise have been overlooked in evaluation of the observational data. (C) 2008 Elsevier B.V. All rights reserved
