深层海水

有孔虫壳体的Mg/Ca比值测定是目前估算海水古温度最受重视的方法，适用于低纬和高纬、表层和深层海水古温度的测定。

Measurement of Mg / Ca ratio of foraminifera shell is the most popular means in calculating seawater paleotemperature now . It is applicable in low and high latitude areas , to determine surface and deep seawater temperatures .

文章还指出进一步开展菲律宾海沟中-南段海域表层、深层海水~（14）C浓度变化梯度研究的必要性。

The paper points out that it is necessary to further study the gradient change of ~ ( 14 ) C concen-tration in surface and deepwater in the middle and southern section of the philippine Trench .

对大部分国家来说，从这些新获得的海底陆地得到的第一件好处是石油或天然气，这两样能源现在都能很容易地从深层海水提纯。

For many countries , though , the first booty from any newly acquired seabed will be either oil or gas , both of which can now be extracted fairly easily from deep water .

台风产生的海面气旋式风应力以及强烈的混合过程，对上层海洋与深层海水之间的热量、能量和物质交换产生重大影响，因此研究海洋对于台风过程的响应特征具有重要的科学意义。

The cyclonic stress on the sea surface and the strong mixing processes forced by the typhoon play an important role in the processes of the heat , energy and mass exchange between the upper ocean and the deep ocean .

从表层至10m或30m深层的海水区域，分布有丰富的海洋微生物。
