A Study of Dissolved Gas Anomaly as a Result of Ice Formation Under Winter Arctic Conditions

这个项目是对北极圈海水中溶解的氦、氦、氩、氪和氙气的浓度进行分析。由于海冰的形成涉及氦的清除和其他惰性气体的排斥，例如，氦/霓比可以用来推断海冰的冻结/融化/再冻结循环。加入氚数据可以确定深水样品的年龄，从某种意义上说，这是样品中溶解气体最后一次与大气达到平衡的时间。这项技术将被应用于中尺度涡旋中的水的下涌。野外工作将在MIZEX 87期间进行，MIZEX 87是挪威和希腊海域的一个国际合作海洋学项目。将使用挪威的M/S哈康·莫斯比号船。支持这一项目的水文数据将由船上的其他调查人员获取。

This project is an analysis of arctic sea water for the concentration of dissolved helium, neon, argon, krypton, and xenon. Since the formation of sea ice involves the scavenging of helium and the rejection of the other noble gases, the helium/neon ratio, for example, may be used to infer the freezing/melting/refreezing cycles of sea ice. The addition of the tritium data allows the determinationof the age of a deep water sample, in the sense of giving a time sincethe dissolved gases in the sample had last been in equilibrium with the atmosphere. This technique will be applied to the downwelling of water in mesoscale eddies. The field work will be carried out during MIZEX 87, an internationallycooperative oceanographic program in the Norwegian and Greeland Seas. The M/S HAAKON MOSBY, a Norwegian ship, will be used. Hydrographic data to support this project will be taken by other investigators on board the ship.
