Measurement and Interpretation of CFCs in the Japan/East Sea

9818937 warner在这个项目中，pi将在日本/东海（JES）的水文调查期间测量和解释氯氟烃（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的南部，由R/V梅尔维尔号进行，另一次在北部，由俄罗斯船只进行。由于相对较浅的海底和较深的内陆，JES的大部分地区与毗邻的北太平洋隔绝。在深度超过500米的地方，温度和盐度的变化非常小，很难解决深层循环和通风问题。最近的初步测量显示，深水中含有大量的氯氟烃，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.
