A great research documentary on the extreme depths of the Mariana Trench and the mind blowing unseen sea creatures. Very well narrated documentary by David Attenborough. The Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometers east of the Mariana Islands; it is the deepest oceanic trench on earth. The maximum known depth of Marian Trench is 10,984 meters however, some unrepeated measurements place the deepest portion at 11,034 meters.

This NHK documentary is all about the facts and under water life in the deepest sea floor at about 8KM to 10KM below the water level. A hair-raising film on the descent into the Mariana Trench where water exerts a pressure of 1,086 bars (15,750 psi) and the temperature is between 1 to 4 °C (34 to 39 °F).

Kudos to the cameraman who can hold his breath that long.

It's official. David Attenborough MUST live forever. He's truly the best narrator.

Who else just randomly watch nature docs like these every once in a while?

Sir David Attenborough is a national treasure. He makes every nature documentary that much more engaging.

Great documentary, too bad the music kept drowning out David Attenborough's wonderful narration.

I love these types of documentaries with Sir David Attenborough. However, as an older person with a high frequency hearing problem, the loud music makes it hard to understand the dialog.

The music was a bit to loud for me, I love hearing Davids voice but here he was almost drowned out because of the music imo

I'm fascinated with space. Yet there is an entire different unknown world in the ocean

The guy who conducted the music for this documentary also conducted music for all of the studio ghibli movies!

Turn that damn music off. I can't hear the narrator

I found the music to be very annoying. At times you can barely hear Attenborough commentary. I would find it more appealing if it didn't overwhelm the spoken content

For my money, David Attenborough is the most listenable narrator on any History channel. It's like he's sitting right beside me, taking me on all his learned adventures.

It's so cool to see these biologists from completely different lives and cultures get excited about sea life together! Smiles are the universal language

Quite a beautiful documentary, and as always it's a pleasure to have Sir David Attenborough provide the voiceover. But could someone, please, turn down that incessant music a bit? Please?...

The music team on this documentary must have had a meeting and decided that they were getting annoyed with all this David Attenborough talk and it was their time to shine.
