摘要:9815707克奈尔,凯略雷根州立大学研究人员将检查博福特海的水和沉积物中钡的存在,作为海洋洋流携带离开大陆架的颗粒的河流来源的示踪剂。钡示踪剂已被证明是一种有效的示踪剂,用于确定沿海和盆地区域之间的交换过程,因此,将是一个很好的方式来检查的路径和交换率的碳从生产大陆架深盆地。 调查人员将检查水样和沉积物收集器中的钡,并在模型中使用测量结果来揭示北冰洋的近海环流模式。 继续开发钡分析仪的新仪器,可用于测量船上的钡。该项目是陆架-盆地相互作用项目的一个重要组成部分,该项目旨在研究控制碳从具有生物生产力的北冰洋大陆架向深海盆地迁移的过程。 该项目的成果将为2002年在同一地理区域规划陆架盆地相互作用项目第二阶段大型实地方案提供投入。
英文摘要
ABSTRACTOPP-9815707FALKNER, KELLYOREGON STATE UNIVERSITYThe investigator will examine the presence of barium in the water and sediment in the Beaufort Sea as a tracer for river sources of particles that are carried off the continental shelf by oceanographic currents. The barium tracer has been shown to be an effective tracer for determining exchange processes between coastal and basin regions and, as such, will be an excellent way to examine the pathways and exchange rate of carbon from the productive continental shelf to the deep basin. The investigator will examine water samples and sediment-trap sediments for barium and use the measurements in a model to reveal offshore circulation patterns in the Arctic Ocean. Continued development of a new instrument for a barium analyzer that can be used to measure barium from a ship. The project forms an important component of the Shelf-Basin Interaction project which is designed to examine the processes that control the transport of carbon from the biologically productive Arctic Ocean continental shelf to the deep basin. The results of this project will provide input for planning a large Phase 2 field program of the Shelf Basin Interactions project in 2002 in the same geographic area.
