Our transcription: But most of what we know about this remote and alien environment has not been learned by personal observation.
It's been obtained by using indirect techniques.
The high technology of sea floor exploration has produced a wide variety of remote sampling tools and marine robots that act as the eyes, and the ears, and the hands of the scientists who study the deep ocean floor.
Studying the ocean floor using these remote techniques has produced a vast wealth of information, and the more we learn about it, the more intriguing it seems.
In fact, the deep sea floor has not only played a prominent role in the evolution of our planet.
It remains the most tectonically vigorous region on Earth.
