This project will measure the flux of the calcareous phytoplankter Florisphaera profunda in sediment traps from the Arabian Sea and compare the results with surface and downcore sediment data. Data will be used to test the hypothesis that relative abundance of this species is a tracer for primary production. The temporal and spatial variability across the upwelling system will allow comparison of species abundance to a wide range of conditions of upper-ocean structure and productivity.

该项目将测量阿拉伯海沉积物陷阱中钙质浮游植物深部浮游植物的通量，并将结果与表层和岩心以下的沉积物数据进行比较。数据将被用来检验该物种的相对丰度是初级生产力的示踪剂这一假设。整个上升流系统的时间和空间变异性将使物种丰富度能够与上层海洋结构和生产力的广泛条件进行比较。
