　　这次深潜的最深处是海平面以下1101米，蛟龙号在那里取回了一些玄武岩的样本。

　　"We have also caught sight of corals, sea lilies, anemones⁴, and large fishes like sharks above 420 meters," said Yang Gang, a senior engineer on board the submersible.

　　潜水器上的高级工程师杨刚称：“我们还看到了珊瑚、海莉、海葵和如鲨鱼一样的超过420米的大型鱼类。”

　　Yang said that the new discoveries could shed new light on the study of the South China Sea's formation and evolution, biodiversity, and the cause of the seamount chain in the area.

　　杨刚表示，这些新的发现可以进一步阐述中国南海的形成与演变、生物的多样性和海山链形成的原因。

　　Instead of using trawling as a sampling method, Jiaolong is able to conduct refined sampling mission and obtain ample samples, said Shi Xuefa, a researcher with the State Oceanic Administration.

　　国家海洋局的研究员石学法称，除了捕捞式的采集方法，蛟龙号还可以精细抽样任务并获得丰富的样本。

　　Named after a mythical⁵ dragon, Jiaolong reached its deepest depth of 7,062 meters in the Mariana Trench⁶ in June 2012.
