Down down deeper and down

[Dr Jekyll]

Scroll down to see what weird creatures live underwater. It's funny how the darker it gets the more scary the fish look.

I enjoyed that, thanks for sharing.

That was exciting!!

[anonymous-user]

That was great

What i found amazing was the depths that air breathing creatures dive to, especially penguins and turtles. But over 3,000 metres for a whale. Respect!

Is that the max depth they get to? You don’t fish for them that deep.

I have caught Mahi Mahi at the surface, barracuda too.

Well presumably the polar bear doesn’t normally live at 22 metres below sea level.

How does the sixgill shark (1730m) know when it’s night time so it can come shallow?

[Slackline]

I've been down to 35m 30m scuba diving and can feel the pressure exerted by the water there. The guy that's been to 322m must have been neigh on crushed!

Thanks for sharing. Surprised an elephant seal can dive to more than 2km!

They do when all the ice has melted.

He wasn't the deepest though, the bloke from the Guinness Book of Records who was down there to check his depth went deeper

All that effort and some tt with a clipboard and camera goes past you

Presumably his tank had to be super pressurised, beyond normal scuba pressure, to allow him to breathe at that depth.

Hi All,

Top lurking I know!

I just saw this post and if you are interested in Deep Deep - as deep as you can go deep - then have a look here: https://caladanoceanic.com/

The mother ship also has a Facebook page: https://www.facebook.com/Dssvpressuredrop/

We are currently completing the first manned dive on the Philippine Trench (the 3rd deepest place on the planet) with the sub just on its way back up from 10045m / 32956ft....

Thanks for the links.

The making of limiting factor was a really interesting little documentary.

That Victor fella has led an interesting life!

No, a conventional scuba tank will do just fine. At 300 meters, the water pressure is 30 bar. A standard scuba tank will be 200 - 300 bar depending on spec. You would need a regulator that can deliver gas at 30 bar (I have no idea if a standard one will work....almost certainly not!), and you will rip through a huge volume of air. You also won’t be breathing air - at that pressure, what we breathe on the surface will kill you. They’ll be breathing some weird helium/nitrogen/oxygen mix, and changing gas mixtures as they change depth - because the stuff they breathe on the bottom will kill you on the surface.

I respect the geeky side of this, and have been to 70 meters in good conditions, but I have absolutely no fking idea why people go to these depths! But then, I have no desire to climb Everest either. If you want to understand how barking mad this stuff is, read this:

The world record for freediving (ie no tank, just holding breath) is over (..under?) 300m. I hadn't realised it was so close to the scuba record.

Freediving record: 316m.
Scuba record: 332m.

The Scuba guy came back up from the deep over 15 hours. The Freediving guy did it in a few minutes.

Aside: I quite like "the big blue", 1988 film about unlimited free diving. it's loosely based on the life of a real guy called Jacques Mayol.

That is very close indeed
