ABSTRACTOPP-9815132STEPHENS, MARKMIAMI UNIVERSITYThis study will utilyze a radon isotopic study to determine transport rates and mixing patterns of water from the continental shelf to the deep basin. The rate of decay of the naturally occurring radon is known, therefore the activity ratio of radon isotopes will yield information on the oceanographic processes transporting the radon to the basin. The data from the Beaufort Sea derived in the project will be used in a circulation model to validate the results. The project is very important to understanding the rate at which carbon is transported between the continental shelf and deep basin because it controls the availability for biologic production in the Arctic Ocean. 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.

摘要-9815132斯蒂芬斯，马克迈阿密大学本研究将利用氡同位素研究来确定水从大陆架到深盆的输送速率和混合模式。 天然存在的氡的衰变率是已知的，因此氡同位素的活性比将产生关于将氡输送到盆地的海洋学过程的信息。 来自博福特海的资料将用于环流模式中以验证结果。 该项目对于了解碳在大陆架和深盆地之间的传输速率非常重要，因为它控制着北冰洋生物生产的可用性。 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。
