This proposal is part of an integrated scientific investigation to study the properties of the Arctic ocean, atmosphere, sea-ice and biology in the Northeast Water (NEW) Polynya, which occurs near northeastern Greenland, in order to gain an integrated understanding of Arctic shelf-slope processes. This element of the NEW program will measure Tritium as a chemical tracer to determine how much Atlantic water may be recycled in the region, how effective the gas exchange is through the polynya surface, and how much ice forms during the freezing season. Tritium- helium ages will provide corroborative data for biological studies directed at determination of oxygen utilization rates, a major concern of the program and therefore serve as important collaborative input to the NEW Program.

该提案是一项综合科学调查的一部分，该调查旨在研究格陵兰岛东北部附近的东北水域（NEW）冰峡的北冰洋、大气、海冰和生物特性，以获得对北极大陆架斜坡过程的综合理解。新计划的这一要素将测量氚作为化学示踪剂，以确定该地区有多少大西洋水可以被循环利用，通过多冰湖表面的气体交换有多有效，以及在冻结季节形成了多少冰。氚-氦年龄将为生物研究提供确确性数据，以确定氧利用率，这是该计划的主要关注点，因此将作为新计划的重要合作输入。
