Investigation of Deep and Bottom Water Formation in the Western Weddell Sea from Measurement of CFCs on Samples Collected during the Anzone Project

9317166这项拟议的工作是对韦德尔海冰营漂流和RVIB N.B.Palmer号两次巡航过程中收集的约900000个水样进行分析，以获取氯氟烃(氟氯化碳)。结果将与水文数据集和其他示踪剂数据集合并，以确定底水形成的时间尺度和路径。在火焰密封玻璃安瓶中收集水样的技术使人们不再需要立即对氯氟化碳进行分析，并将能够分析更多来自冰营的水样。合并后的数据集将用于确定新形成的底水的来源，估计将大陆架水转化为底水所需的时间，并确定新形成的底水与大气中氟氯化碳浓度不平衡的程度。***

9317166 Smethie This proposed work is the analysis of approximately 900 water samples collected in the course of the Weddell Sea Ice Camp (ISW-1) drift and two cruises of the RVIB N.B. Palmer for chlorofluoro- carbons (CFC's). The results will be merged with the hydrographic data set and other tracer data sets to determine time scales and pathways of bottom water formation. The technique of collecting of water samples in flame-sealed glass ampoules has obviated the need for their immediate analysis for CFC's, and will allow the analysis of a greater number of samples form the ice camp. The merged data sets will be used to identify sources of newly-formed bottom water, to estimate the time required to convert shelf water to bottom water, and to determine the extent to which the newly-formed bottom water is in disequilibrium with atmospheric CFC concentrations. ***
