9310634 GOWING As part of the U.S. JGOF Arabian Sea Process Study (ASPS), this study is aimed at understanding how changes in species composition and abundance in the pelagic community of primary producers, zooplankton grazers, and microheterotrophic decomposers impacts the biochemical cycling of carbon in the Arabian Sea. Physical forcing by the monsoon winds triggers seasonal burst of biological productivity in this region. As in other ecosystems, this production will involve a temporal succession of species of producers, grazers, and decomposers-- each with differing capacities to influence carbon production, respiration, physical repackaging (e.g., shredding, fecal pellet production), and transport-- and the PIs propose to follow these changes over time. Therefore, while other investigators involved in the ASPS, will be making relatively gross chemical measurements of the rates of carbon production, mineralization, and transport, this study will provide valuable insights into the actual contributions of specific biophysical and ecological mechanisms accounting for those rates.

作为美国JGOF阿拉伯海过程研究（ASPS）的一部分，本研究旨在了解初级生产者、浮游动物食草者和微异养分解者的中上层群落物种组成和丰度的变化如何影响阿拉伯海碳的生化循环。季风的物理强迫触发了该地区生物生产力的季节性爆发。与其他生态系统一样，这种生产将涉及生产者、食草者和分解者物种的时间演代——每种物种对碳生产、呼吸、物理再包装（如粉碎、粪便颗粒生产）和运输的影响能力不同——而pi建议随着时间的推移跟踪这些变化。因此，当其他参与ASPS的研究人员将对碳产生、矿化和运输的速率进行相对粗略的化学测量时，这项研究将为解释这些速率的特定生物物理和生态机制的实际贡献提供有价值的见解。
