同时对马尾藻海表层水中的颗粒浓度和深水中的颗粒通量进行的测量表明，在生物成分方面，两者之间存在密切的耦合。悬浮物的浓度似乎遵循与初级生产力和深水颗粒通量相似的年度周期。尽管地表水中颗粒铝的浓度在这个循环中似乎是随机变化的，但铝向深水的迁移与有机物的快速向下输送密切相关。
Concurrent measurements of particle concentrations in the near-surface water and of particle fluxes in the deep water of the Sargasso Sea show a close coupling between the two for biogenic components. The concentrations of suspended matter appear to follow an annual cycle similar to that of primary production and deepwater particle flux. Although the concentration of particulate aluminum in the surface water appears to vary randomly with respect to that cycle, the removal of aluminum to deep water is intimately linked to the rapid downward transport of organic matter.
