9401895 Weiss In this project, the PI will carry out measurements of anthropo- genic Chlorofluorocarbons (CFC0, F-11 and F-12, along the latitude 20 degrees South, the IO WHP section denoted as I-3. The PI will also provide CFC analytical equipment for use by other measurement groups for other IO sections. Specific objectives of this work in- clude studies of propagation rates of Antarctic Bottom Water into the deep Indian Ocean and studies of mixing and transport processes in the thermocline and Antarctic Intermediate Water of this region. Results will be applied to improving models of mixing processes and determining their role in global climate change, and, particularly, on the oceanic modulation of carbon dioxide and other important atmospheric constituents. ***

9401895韦斯在本项目中，PI将对人类产生的氯氟烃（CFC 0、F-11和F-12，沿着南纬20度，IO WHP部分表示为I-3）进行测量。 PI还将为其他IO部门的其他测量组提供CFC分析设备。 这项工作的具体目标包括研究南极底层水向印度洋深海的传播速率以及研究该地区温跃层和南极中层水的混合和输送过程。 研究结果将用于改进混合过程的模型，并确定其在全球气候变化中的作用，特别是海洋对二氧化碳和其他重要大气成分的调节作用。 ***
