Oceans are becoming saltier because of global warming.

由于球变暖，海洋盐度升高。

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

水源的盐度并不是唯一的问题。

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

但之后每年，水的盐度都越来越高。

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

不过我们测量盐度时使用的方法还蛮有趣的。

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

这背后的科学道理同样在于高盐度。

In the water from the rock pools?

指的是测量从潮水坑里取出的水的盐度？

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

我们认为地球上的生命起源于高盐度的海洋。

Today, the lake is around 50% saltier than the Pacific Ocean.

，湖的盐度比太平洋高出约 50%。

There is a direct relationship between salinity and density.

盐度和密度之间有直接关系。

No, I'm not. French fries have three variables...crispiness, saltiness and shape.

不，我没有。薯条有三种变量...脆度、盐度，和形状。

As the lake dries up, it's getting too salty to sustain life.

随着湖水干涸，湖水盐度会越来越高，盐水蝇幼虫无法生存。

As the sea creeps into these fresh-water marshes, however, rising salinity is hampering rice production.

然而，随着海水慢慢渗入这些淡水沼泽，不断上升的盐度阻碍了水稻生产。

These two factors together, temperature and saltiness, are crucial to how the ocean conveyor circulates.

这两个因素，温度和盐度，对海洋输送机的循环至关重要。

It's burning salsa. I'm hoping the acidity and salinity combined with electricity will corrode the lug nut off.

烧着的莎莎酱，希望酸性和盐度与电结合可以腐蚀部分螺母。

The higher the salinity, the greater the density of the water.

盐度越高 水的密度就越大。

It's the salty Dead Sea that's between Israel and Jordon and it has the lowest elevation on Earth's surface.

答案是盐度很高的死海，这是地球表面海拔最低的地方。

This is the source of the salinity of the Dead Sea.

这是死海盐度的来源。

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

最重要的是盐度变化、含盐量和温度变化，有点像水下的气象气球。

In fact, this explanation applies to the salinity of other water bodies as well.

事实上，这一解释也适用于其他水体的盐度。

The threshold is - we're kind of at the threshold. So if things get any saltier, we're super, super worried.

我们处在临界点上。果湖水盐度越来越高，我们会极度担忧。
