I always tell everyone, it's like whatever you see on land, all the mountains, the ridges, even the meandering rivers, you can also see that on the seafloor, but on a massive scale.

我總是告訴大家，就像你在陸地上看到的一切，所有的山脈、山脊，甚至蜿蜒的河流，你都可以在海底看到，只不過規模更大。

Hi, my name is Haya Roperas, and I am the lead mapping coordinator for Inkfish.

大家好，我叫哈亞-羅伯拉斯（Haya Roperas），是 Inkfish 的首席製圖協調員。

So here in the Nova Canton trough, we've got a suite of scientific assets that we're deploying every single day while we're here.

是以，在諾瓦坎頓海槽，我們每天都在這裡部署一整套科學資產。

是以，首先，我們要繪製地圖。

So that's using our EM124, which is a multi-beam echo sounder.

這就是使用我們的 EM124 多波束回聲測深儀。

So that not only maps the shape of the seafloor, but it also gives us information on the composition.

是以，它不僅能繪製海底形狀圖，還能為我們提供有關海底成分的資訊。

So it's something called backscatter intensity.

First thing is that we pick our locations for all our deployments, including the sub dives based on the mathematical data, because that's where we will see the topography of the terrain of the seafloor.

首先，我們要根據數學數據來選擇所有部署地點，包括下潛地點，因為我們將在那裡看到海底的地形地貌。

So we don't want to put the landers on a very slopey area where it will roll down.

是以，我們不想把著陸器放在會滾落的斜坡上。

Xena, Xena, Proc 2, all copy, decks awash, decks awash.

謝娜，謝娜，Proc 2，全部複製，甲板氾濫，甲板氾濫。

The mapping systems that we have also can give us the idea of how hard or soft the seafloor material is.

我們擁有的測繪系統還能讓我們瞭解海底材料的軟硬程度。

All right, I'm just going to bring us onto our heading.

好了，我現在要把我們帶到標題上。

After we pick the site, the sub team and the scientists will decide on how they will be doing the transect when they reach the seafloor.

選定地點後，分隊和科學家將決定到達海底後如何進行橫切。

And that is also guided by what we see in the mathematical data.

這也是我們從數學數據中看到的。

Sometimes it will be a very boring flat, and then suddenly there's a bump in there.

有時，這將是一個非常無聊的平地，然後突然有一個凹凸不平的地方。

Like, see, if we look at these two seamounts, we can say that one is relatively new, when the other one has had so many processes that happened to it, like probably eruption, or there's also like so many landslides in there.

比如說，如果我們觀察這兩座海山，我們可以說其中一座相對較新，而另一座已經經歷了許多過程，比如可能是火山爆發，或者那裡也有許多山體滑坡。

So that's one thing that really makes the job exciting, is to be able to see these things.

是以，能看到這些東西才是真正讓這份工作令人興奮的事情。

When you look at the Chepco grid, which is at 450 meters resolution, you only see like  But when we map it, it will be like in different shape and in different kind of ruggedness of the terrain.

當你查看分辨率為 450 米的 Chepco 網格時，你只能看到類似的情況，但當我們繪製地圖時，它會呈現出不同的形狀和不同的地形崎嶇度。

As of the moment, only at least 25% of the entire ocean floor on Earth is mapped.

目前，繪製的地圖僅佔地球整個洋底的至少 25%。

The rule of thumb for me, whenever the vessel is moving, we'll be mapping.

我的經驗法則是，只要船隻在移動，我們就會進行測繪。
