Elemental Tracers And Organic Biomarkers As Proxies of Productivity and Environmental Setting in The Arabian Sea: Suspended Particulate, Sediment Trap, etc.

9310686戴蒙德海洋上层产生的各种无机和有机化学物质可视为其形成时生物和环境状况的指标。在这项研究中，主要调查人员将分析在阿拉伯海过程研究期间部署的沉积物圈闭中积累的一套有机和无机生物指示物质。通过分析时间序列中的圈闭物质并将其与海底沉积物的化学成分进行比较，调查人员期望确定在与季风有关的初级生产事件期间产生的可靠生物标志物，它们(1)反映水柱初级生产力和影响初级生产量的过程，(2)作为潜在的古环境指标持续存在于海底沉积物中。

9310686 DYMOND A variety of inorganic and organic chemical substances generated in upper ocean may be considered indicators of the biological and environmental conditions existing at the time of their formation. In this study, the principal investigators will analyze a suite of organic and inorganic bioindicator substances accumulating in sediment traps deployed during the Arabian Sea Process Study. By analyzing trap material in time series and comparing it to the chemical composition of seafloor sediments, the investigators expect to identify reliable biomarkers generated during monsoon- associated primary production events that (1) reflect water column primary productivity and processes affecting primary production and (2) persist in seafloor sediments as potential palenvironmental indicators.
