The role of zooplankton in N-, P- and C- cycling and for the oxygen budget of tropical oxygen minimum zones (B08)

浮游动物是有机物质垂直运输的重要因素，也是海洋N、P、C、O循环的重要因素。对浮游动物丰度、生物量和放牧活动的观察将使我们能够表征氧气分布的大小变化如何影响浮游动物在控制这些元素循环中的作用。生物地球化学模型研究将通过浮游动物的垂直迁移和颗粒物质通量来解决异养过程对底物供应的依赖。

Zooplankton is an important factor for the vertical transport of organic material and essential for the cycling of N, P, C and O in the ocean. Observations of zooplankton abundance, biomass and grazing activity will enable us to characterize how large and small scale changes in the oxygen distribution impact the role of zooplankton in controlling these elemental cycles. Biogeochemical model studies will address the dependence of heterotrophic processes on substrate supply via diel vertical migrations of zooplankton and particulate matter flux.
