该项目将分析通过南大洋水域沉降的颗粒中的微量元素(Ba、Al、Ti、Fe和Mn)。这些微量元素被假设为海洋生产力的示踪剂和碳从上层海洋转移到深海和沉积物的指标。某些元素,特别是Al/Ti的比值,可能反映了与硅质浮游生物有关的生产力。顺序浸出与统计分析相结合,将用于确定与不同沉积物成分有关的元素。
英文摘要
This project will analyze trace elements (Ba, Al, Ti, Fe and Mn) in particles that settle through waters of the Southern Ocean. These trace elements are hypothesized to be both tracers of ocean productivity and indicators of carbon transfer from the upper ocean to the deep ocean and the sediments. Some elements, particularly the ratio Al/Ti, may reflect productivity linked to siliceous plankton. Sequential leaching combined with statistical analyses will be used to identify the elements associated with different sediment components.
