The phytoplankton trails the edge of the ice and can stretch for nearly fifty kilometers.

浮沿着冰层的边缘生长，绵延可达近五十公里。

This is perfect for photosynthesis and photosynthesis is dope, Hello phytoplankton productivity!

这非常适合光合作用，而光合作用又是兴奋剂，您好，浮的生产力！

So if there's an increase in phytoplankton, it will start to attract larger lifeforms.

因此，如果浮增多，就会开始吸引更大型的生。

Okay, so there's a different class of plankton called phytoplankton.

好吧，所以有一种不同的浮生叫做浮。

There are some phytoplankton, some photosynthetic plankton that also undergo vertical movements.

有一些浮，一些光合作用的浮生也进行直运动。

Phytoplankton serve as the base of ocean food webs.

浮是海洋食网的基础。

These nutrients help to form phytoplankton -- extremely small organisms that take in carbon.

这些营养质有助于形成浮——能吸收碳的极小生。

But these giant creatures just didn’t have enough food to get any giant-er than that.

数百万年前 洋流的变化将海底无数的养分冲至海面区 富含营养的浮堆 当然吸引了巨量的浮生聚集。

There's these microscopic organisms called phytoplankton.

海洋中有一些微生，称为“浮”。

Those phytoplankton do something really incredible.

这些浮的作用非常神奇。

And since the ocean's surface waters generally have an abundance of these resources, phytoplankton are everywhere.

由于海洋表层水通常拥有丰富的这些资源，浮随处可见。

Much of the rest is unattached algae, known as phytoplankton, and tiny animals, known as zooplankton.

而其它大多数是独立生长的海藻，被称为浮，还有被称为浮动的小动。

During the day, phytoplankton use sunlight to turn dissolved carbon dioxide into energy and build their own cells.

浮在白天期间利用阳光将溶解的二氧化碳转变为能量，并用来建造自己体内的细胞。

In summer, the powerful nonstop rays of the sun create a bloom of phytoplankton and microscopic plant life.

夏季时强力而持续的太阳光照使浮生长旺盛，而微生也很兴旺。

Ocean ecosystems are finely balanced and any change in the phytoplankton will send ripples across the food chain.

她告诉美国有线电视新闻网，海洋生态系统处于微妙的平衡状态，浮的任何变化都会在整个食链中产生连锁反应。

And we're making sure that this doesn't have any bad effect on the phytoplankton diatoms in the ocean.

我们还要确保这不会对海洋中的浮硅藻造成任何不良影响。

Algae need light, so must live near the surface—as must the zooplankton and other animals that need the phytoplankton.

海藻需要光线，所以必须生活在接近海面的区域—还有需要浮的浮动和其它动也同样如此。

Well, a number of things from floating sand, phytoplankton and all sorts of living organisms that aren't just fish.

这有很多因素，比如漂浮的沙粒，浮以及各种包括鱼在内的有机生体。

Phytoplankton is one of the biggest resources for food for every single species in the ocean.

海洋生主要以浮为食。

To understand why, we need to look at some of the ocean's most ubiquitous organisms: phytoplankton.

要了解其中的原因，我们需要看看海洋中无处不在的生：浮。
