9312694 Lee Because of the monsoon-driven seasonality of primary production in the Arabian Sea, the Arabian Sea Process Study affords an opportunity to follow a variety of biomarker compounds from their point of origin in the photic zone to their eventual burial and preservation in seafloor sediments. In this project, the principal investigators will sample and characterize some 100 different particulate biochemical compounds -- lipids, pigments, amino acids, and carbohydrates -- at their point of origin in the surface ocean, through transformation in deeper water as they settle in deeper water as they settle in particulate form to the seafloor, and in surficial and subsurface sediments. Analysis of data collected during and between monsoon events will permit the investigators to characterize the reactivity and transformations of these organic substances and to assess their potential for sedimentary preservation as marine paleoenvironmental indicators. ***

9312694 Lee 由于阿拉伯海初级生产受季风驱动的季节性，阿拉伯海过程研究提供了一个机会来跟踪各种生物标记化合物从透光区的起源点到最终埋藏和保存在海底沉积物中的过程。 在这个项目中，主要研究人员将对大约 100 种不同的颗粒生化化合物（脂质、色素、氨基酸和碳水化合物）进行采样和表征，这些化合物来自表层海洋，通过在更深水中的转化，当它们以颗粒形式沉降到海底时，以及在表层和地下沉积物中。 对季风事件期间和之间收集的数据进行分析将使研究人员能够表征这些有机物质的反应性和转化，并评估它们作为海洋古环境指标的沉积保存潜力。 ***
