Schooling in huge numbers, they mingle in the currents and cruise along the seamounts.

它们成群结队，混在水流中，沿着海底山游弋。

While submarine canyons plummet into the deep sea, rocky formations, called seamounts, rise from  the darkness.

当海底峡谷坠入深海时，被称为海山的岩石构造从黑暗中升起。

Seamounts are the remnants of dormant volcanoes, some of which climb from the  deep sea all the way to the ocean's surface.

海山是休眠火山的遗迹，其中一些火山从深海一直攀升至海洋表面。

Undersea volcanic activities give rise to seamounts – underwater mountains that are formed on the ocean floor but do not reach the water surface.

海底火山活动形成海山——形成于海底但未到达水面的水下山脉。

As recently as 2019, for example, researchers found several thousand new underwater mountains, known as seamounts, by measuring the effects of their gravity on the ocean's surface.

例如，就在2019年，研究人员通过测量海洋表面重力的影响发现了数千座新的水下山脉，即所谓的海山。

This comes after the U.S. Navy released a new investigation report about a month after the incident, which said the submarine crashed into an unknown seamount in the waters.

此前，美国海军在事件发生约一个月后发布了一份新的调查报告，称该潜艇撞上了该水域一座不知名的海底山。

Seamounts create huge, three-dimensional  ecosystems, providing habitats for a variety of marine organisms.Species like sea stars and  deep-sea corals latch on its rocky cliffs, while fish and migratory animals, like whales, feed  on numerous species of shellfish and plankton.

海山创造了巨大的三维生态系统，为各种海洋生物提供了栖息地。海星和深海珊瑚等物种依附在其岩石悬崖上，而鱼类和鲸鱼等迁徙动物则以多种贝类和浮游生物为食.
