This award will support the participation of Dr. Douglas Wallace, Brookhaven National Laboratory, in the Swedish Antarctic Expedition scheduled for December 1988 and January 1989 in the Weddell Sea, one of the world's greatest deep water formations. During the expedition Dr. Wallace will make time series measurements of chlorofluoromethanes (CFMs). The collected data will then be interpreted in conjunction with physical and geochemical parameters measured by Swedish co-investigators from the Department of Marine and Analytical Chemistry, University of Goteborg, which is one of the world's major centers of expertise on marine chemistry. Chlorofluoromethanes can be used as transient tracers of ocean circulation and mixing over decadal timescales. The proposed CFMs study can make a significant contribution to the understanding of oceanographic and geochemical processes in the Weddell Sea. The study of dissolved CFMs as time-dependent tracers in the ocean is especially valuable in this region, where globally important deep and bottom water types are formed. Both the U.S. and Sweden will clearly benefit from the proposed work. The CFM data base previously collected by U.S. scientists will be expanded and the Swedish expedition will be greatly strengthened by the addition of CFM measurements to the shipboard program.

这项奖金将支助布鲁克海文国家实验室的道格拉斯华莱士博士参加定于1988年12月和1989年1月在威德尔海进行的瑞典南极考察，威德尔海是世界上最大的深水层之一。在考察期间，华莱士博士将对氯氟甲烷（CFMs）进行时间序列测量。然后，将结合哥德堡大学海洋和分析化学系的瑞典合作调查人员测量的物理和地球化学参数对收集的数据进行解释，哥德堡大学是世界上主要的海洋化学专业中心之一。氯氟甲烷可以作为海洋环流和混合的瞬态示踪剂在十年的时间尺度。建议CFMs研究可以在威德尔海的海洋学和地球化学过程的理解作出重大贡献。溶解的CFMs作为海洋中随时间变化的示踪剂的研究在这一区域特别有价值，在这里形成了全球重要的深水和底层水类型。显然，美国和瑞典都将从拟议的工作中受益。美国科学家以前收集的CFM数据库将得到扩大，瑞典探险队将通过在船上计划中增加CFM测量来大大加强。
