Tracer Studies in the Black Sea

这是一个关于氚的研究。放射性碳，溶解的氦氖和氩在黑海。早期的数据显示，1700米以下有可测量的氚，而700米至1700米之间没有。这可以用地中海海水下沉形成黑海底水来解释。对底部氚的进一步测量将使我们能够构建这种同位素的演变，并基于先前的观察来测试模型。详细的溶解氦测量将提供关于沉积通量的稳定性、放射性氦的积累以及从底层上涌的速率的信息。这些测量将用于模拟地中海输入的输入和混合率，以及寻找减少火星车输入对黑海质量平衡的预测影响。

This is a study of tritium. radiocarbon, dissolved helium- neon, and argon in the Black Sea. Earlier data show that there is measurable tritium below 1700m while between 700m and 1700m there is none. This can be explained by the sinking of Mediterranean water to form the Black Sea bottom water. Further measurements of tritium in the bottom will allow us to construct the evolution of this isotope, and to test the models based on the previous observations. Detailed dissolved helium measurements will provide information on the constancy of the sedimental flux, on the accumulation of radiogenic 3He and on the rate of upwelling from the bottom layer. These measurements will be used to model the input and mixing rates of the Mediterranean input as well as to search for the predicted effects of diminished rover input on the mass balance of the Black Sea.
