摘要: |
本文指出,海水中Ca和Mg的分布变化不仅能定性地鉴别水系的类别,而且还能半定量地划出它们的流经范围。在夏季,位于32°N、126°E东海海区周围Ca和Mg分布异常,含量较其它海区都高。这与海底分布着的一块孤立的软泥位置十分吻合。在该海区,由于涌升流存在,将海底沉积物中溶解态Ca和Mg带至上层。可见,Ca和Mg的分布异常区与水系、上升流及海底沉积物都有非常密切的关系。 |

AN ANALYSIS OF RELATION OF THE DISTRIBUTION OF CALCIUMAND MAGNESIUM IN SEA WATER TO THE CURRENT SYSTEMSAND THE UPWELLING IN THE EAST CHINA SEA |
|
Abstract: |
The distribution of dissolved elements bears close relationship with movement of current systems. Horizontal distribution of dissolved Ca, Sr and Mg revealed that isolated high content of these elements appeared at every water layer. Its center is located near 32°N, 126°E. The authors point out this isolated high cocentration of dissolved elements bears close relationship with the upwelling in SW of Cheju Island in summer. |
