Attempts were made to calculate Earth's age from the thickness of surviving sedimentary rock and from the current level of the oceans' salinity.

人们曾试图根据现存沉积岩的厚度和目前海洋的盐度水平来计算地球的年龄。

That would have altered the heat - and salinity-driven dynamics of the area rapidly, stopping the warm current from travelling so far north.

这可能改变了海洋的热量分布，并且这一区域内海水的盐分也迅速发生的变化，可能这一切阻止了暖流流向足够远的北方。从而使全球气候发生了巨变。

The mechanism of continuous demineralization using EDI technology is explained through describing the effects of the salinity and flow rate of raw water on the applied electric current.

介绍了EDI技术的基本特点，通过描述原水中含盐量和流速对膜堆的电流的影响，对EDI连续脱盐的机理加以解释。

In addition to a sea floor mapping project, the researchers will make chemical analyses of water samples that will help them determine the temperature, salinity and composition of a strong circumpolar current that flows around the boundary of the Arctic Ocean.
