This project is an analysis of the distribution of two species of chlorofluoromethanes (freons) in the southern Weddell Sea. The samples were obtained by the principal investigator as part of the Filchner III Expedition of the West German research vessel POLARSTERN. The analysis of freons, a time-dependent, anthropogenic tracer in the water column, is part of a collaborative chemical and hydrographical study of the circulation of Ice Shelf Water (a particular water type formed under the Filchner Ice Shelf). The outlow of this water type through the Filchner Depression, its subsequent evolution on the continental slope, and its penetration into the deep Weddell Sea will be followed, and the derived data used to study formation rates and transport paths of deep and bottom water masses in the Weddell Sea. Air samples that were collected on the cruise will be analyzed for freon concentrations in order to determine the extent of equilibrium between the surface sea water and the overlying atmosphere.

本项目是对两种植物的分布进行分析， 氯氟甲烷（氟利昂）在南部威德尔海。 的 样本由主要研究者获得，作为 菲尔希纳三号考察船（英语：Filchner III Expedition of the West German research vessel POLARSTERN） 氟里昂的分析，一种时间依赖的，人为的示踪剂， 水柱，是化学和水文合作的一部分， 冰架水（一种特殊的水型）循环的研究 在Filchner冰架下形成）。 这种水型的外流 通过菲尔希纳凹陷，其随后的演变， 大陆坡，其深入威德尔海将 使用衍生数据研究形成率， 威德尔海深水和底层水团的运输路径。 在巡航中收集的空气样本将进行分析， 氟利昂浓度，以确定平衡程度 在表层海水和上层大气之间。
