?Search teams are racing against time to find a tourist submersible that went missing during a dive to the Titanic's wreck. The search is taking place in a remote area, which makes the operation especially challenging. Communication through water is always very difficult. So once you've lost communication, it's very difficult to locate where it is. One of the big problems with the research is that they don't know whether to look on the surface of the Atlantic or on the seabed. It could be in either place. It's very unlikely it's in between. So the very deep water column to try and find your item, so your footprint of your search will be really big. And then you'll have current effects as well. So if the sub is somewhere in the water column, it can be moving around in a non-predictable manner. The submersible vanished in the ocean, approximately 900 miles from Cape Cod, Massachusetts, where the ocean depth is roughly 13,000 feet. The submarine is going to be neutrally buoyant. So it'll be floating just at the surface, most of it under the water, just a small amount breaking the surface. And it's about the size of a large transit van. So and it's painted white. So trying to see that from the air, particularly if they've lost power, so they won't be able to signal, is going to be a real challenge. They are bolted in. So they're trapped inside. So makes signalling more of a challenge. If it is on the seabed, it won't be so much a case of looking for them, but listening for them because we'll be using sonar. And hopefully the crew will then be making some sort of noise on the hull, which can be detected.

Section 1:

1. submersible - 潛水艇 - The tourist submersible went missing during a dive to the Titanic's wreck.

2. remote - 遙遠(yuǎn)的 - The search is taking place in a remote area, which makes the operation especially challenging.

搜索團(tuán)隊(duì)正在競賽時(shí)間，尋找在“泰坦尼克”沉船的潛水艇。搜救正在偏遠(yuǎn)地區(qū)進(jìn)行，這使得行動(dòng)尤其具有挑戰(zhàn)性。水下通訊總是非常困難的。一旦失去通訊，很難定位它在哪里。研究中的一個(gè)大問題是，他們不知道是否應(yīng)該在大西洋表面還是海底尋找?？赡茉趦蓚€(gè)地方之一。很不可能在中間。試圖在非常深的水柱中找到您的物品，因此您的搜索足跡將非常大。然后你也會有當(dāng)下的影響。因此，如果潛艇在水柱中的某個(gè)地方，它可能會以不可預(yù)測的方式移動(dòng)。潛水艇在距離馬薩諸塞州土角大約900英里的海洋中消失，在該處的海洋深度大約為13000英尺。潛水艇將是中性浮力。所以它會漂浮在表面，大部分在水下，只有一小部分露在水面上。它的大小約為一輛大型變速箱。如果他們失去動(dòng)力，因此不能發(fā)出信號，那么在空中嘗試找到它就會面臨真正的挑戰(zhàn)。他們被困在里面。因此，發(fā)出信號會更具挑戰(zhàn)性。如果它是在海底，那么不是尋找，而是依靠聽覺來搜索，因?yàn)槲覀儗⑹褂寐暭{。希望機(jī)組人員隨后會在船殼上制造某種噪音，以便可以檢測到它。
