Oceans are becoming saltier because of global warming.

由于全变暖，海洋度升高。

The salinity of water supplies isn't the only problem.

水源度并不是唯一问题。

The science behind this, again, lies in the high salinity.

这背后科学道在于高度。

Which of the Earth's oceans has the highest salinity or concentration of salt?

地哪个大洋度或浓度最高？

But then the water became more and more salty each year.

但之后每年，水度都越来越高。

But the way we measured the amount of salt was interesting.

不过我们测量度时使用方法还蛮有趣。

In the water from the rock pools?

你指是测量从潮水坑里取出水度？

There is a direct relationship between salinity and density.

度和密度之间有直接关系。

We think Earth's life originated in salty ocean water.

我们认为地生命起源于高度海洋。

答案是度很高死海，这是地表面海拔最低地方。

Most importantly, variations in salinity, that's salt levels, and changes in temperature, a bit like underwater weather balloons.

最重要是度变化、含量和温度变化，有点像水下气象气。

Halobacteria are a kind of single-celled organism that do well in bodies of water with high levels of salt.

嗜细菌是一种单细胞生物，其在高度水体中生长良好。
