9310676 Prell Besides their importance in the zooplankton and as links in the marine food web, foraminifera and radiolaria also produce hard parts that contribute to the flux, respectively, of calcium carbonate and opaline silica from the upper ocean to the sea floor. As part of the Arabian Sea Process Study, scientists from the Woods Hole Oceanographic Institution and Brown University will quantify the effects of the monsoon winds upon the production of foraminifera and radiolaria and upon the flux of their hard parts to the seafloor by examining samples taken from plankton tows, sediment traps, and in sediment cores from the seafloor. Such studies should help us to understand both present- day and historical patterns of oceanic biological production and particle flux associated with the monsoons. ***

9310676有孔虫和放射虫除了在浮游动物和海洋食物网中具有重要作用外，它们还产生坚硬的部分，分别对碳酸钙和蛋白石二氧化硅从上层海洋到海底的通量作出贡献。作为阿拉伯海过程研究的一部分，伍兹霍尔海洋研究所和布朗大学的科学家将通过检查从浮游生物拖网、沉积物捕集器和海底沉积物岩心中采集的样本，量化季风风对有孔虫和放射虫的产生及其坚硬部分向海底的通量的影响。这样的研究应该有助于我们理解与季风有关的海洋生物生产和粒子通量的当今和历史模式。***
