项目摘要
9310684 HEDGES Because of the monsoons-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 particular 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.
9310684由于阿拉伯海初级生产受季风驱动的季节性,阿拉伯海过程研究使人们有机会追踪各种生物标记化合物,从它们在光区的起源点到它们最终埋藏和保存在海底沉积物中。在这个项目中,首席调查人员将对大约100种不同的颗粒生化化合物--脂类、色素、氨基酸和碳水化合物--进行采样和表征,这些化合物的起始点在表层海洋中,通过它们在更深的水中的转化,特别是它们以某种形式沉积到海底,以及在表层和地下沉积物中。对季风事件期间和期间收集的数据进行分析,将使调查人员能够确定这些有机物质的反应性和转化特征,并评估其作为海洋古环境指标的沉积保存潜力。
