Measurement and Interpretation of CFCs in the Japan/East Sea

9818937警告在这个项目中，PIS将在日本/东海(JES)水文调查期间测量和解释氯氟化碳(CFC)浓度，该调查由海军研究办公室资助。计划进行两次调查，一次在JES南部的R/V Melville上，另一次在北部的一艘俄罗斯船只上。由于相对较浅的岩床和较深的内陆，JES的大部分地区与毗邻的北太平洋隔绝。在大于约500米的深度，温度和盐度的微小变化使得解决深层循环和通风变得困难。最近的初步测量显示，深水中有大量的氯氟化碳，这表明，更有针对性的研究将大大有助于了解该地区。

9818937WarnerIn this project, the PIs will measure and interpret Chlorofluorocarbon (CFC) concentrations during a hydrographic survey of the Japan/East Sea (JES), which has been funded by the Office of Naval Research. Two surveys are planned, one in the southern part of the JES on the R/V Melville, and one in the northern part on a Russian vessel. Due to relatively shallow sills and the deep interior, much of the JES is isolated from exchange with the adjoining North Pacific. At depths greater than about 500 meters, the very small variations in temperature and salinity make it difficult to resolve deep circulation and ventilation. Recent preliminary measurements reveal significant amounts of CFCs in the deep water, which suggest that more focused studies would contribute substantially to understanding the region.
