对全球92个海岸带生态系统数据进行的跨生态系统比较显示，海洋浮游植物生物量对营养物质富集有强烈的积极响应，这与以前在淡水湖和水库的湖泊学文献中报道的一般模式高度一致。河口和沿海海洋系统中叶绿素a的平均浓度强烈依赖于水体中总氮和总磷的平均浓度。此外，与淡水生态系统一样，海洋浮游植物的主要生长限制养分的特性似乎通常可以通过水柱总氮：总磷（TN: TP）比率来预测。这种对营养物质的生理反应的相似性可能源于海洋和淡水浮游植物共同的进化史。
A cross-ecosystem comparison of data obtained from 92 coastal zone ecosystems worldwide revealed a strong positive response of marine phytoplankton biomass to nutrient enrichment that is highly consistent with the general patterns reported previously in the limnological literature for freshwater lakes and reservoirs. Average concentrations of chlorophyll a in estuarine and coastal marine systems were strongly dependent on the mean concentrations of total nitrogen and total phosphorus in the water column. Moreover, as is true of freshwater ecosystems, the identity of the primary growth-limiting nutrient for marine phytoplankton appeared to be generally predictable from water-column total nitrogen: total phosphorus (TN: TP) ratios. This similarity in physiological response to nutrients likely derives from the shared evolutionary histories of marine and freshwater phytoplankton.
