So the issue is that we have this titanium sphere that allows us to go down to these extreme depths and come up repeatedly.

所以问题是我们有这个钛球体可以让我们下到这些极端深度并反复上来。

Because of the extreme depth, it was unsafe for divers to actually go down there, so researchers used remotely controlled submersibles to explore the site.

由于深度极深，潜水员实际潜入那里是不安全的， 因此研究人员使用遥控潜水器对该地点进行了探索。

Given that undersea cables can run to some pretty extreme depths, the true crush depth of a US Seawolf submarine is likely well over 3000 feet and will remain highly classified.

鉴于海底电缆可以延伸到极深的海底，美国海狼潜艇的真实承压深度可能远远超过3000英尺，并保持高度机密。
