Deep Dark Secrets

reply to post by Sinter Klaas
during the various ice ages, sea levels around the world were much lower. Most of those holes were above sea level at one time.

A lot or them were sources of fresh water when they were not under the sea, that's why they find human remains there.

cool! I would not handle that! cool pics

Hi.

Thanks. I know, that's why I asked. I don't recall a sea level of 300 feet less then it is now.

The human remains are no older then about 50.000 years or so. Well... That's because mankind left Africa I believe. A fused column takes a long time and the last ice age is said to end around 40.000 years ago .

I think that will narrow down the time period pretty much. Doesn't it ?

reminds me of "the blue hole" in dahab as well, also a very dangerous place to dive fully , great pics ty op for posting on here

I foundseveral references to the lowest sea levels at 18-20,000 years ago. t
The levels were approximately 400 feet below todays.

Imagine a world with a massive atmosphere of oxygen but very low gravity. Would you like to go diving without gear into this oxygen sea and explore life?


This is what these pictures make me think about.

Thanks !

I guess that will be sufficient.

I would love to, but they forgot to issue me with a set of gills.

Seriously...

With a lot more oxygen in the atmosphere, does it not get a little volatile ?
Less gravity will cause sea levels to rise, I think.

Underwater breathing is a problem for us, but theoretically possible. We do survive upt to nine months with fluid in our lungs, so...

Well that's because the placenta feeds us our oxygen, not our lungs.

A planet I once modeled basically had Earth-like Oxygen levels, slightly elevated. It was as large as Uranus or Neptune, but had a surface about the size of something in between the Moon and Mars. Forgive me for saying oxygen sea, lol. Yes, 100% oxygen kills you.

I do love scenes like in those pictures though. It's like a 0 G environment with life. This and the dolphin ring posts have me convinced that the aquatics in Star Trek are a real possibility.

(:30 onwards)

Star and flag to the OP for taking me on a magical journey through gorgeous pictures. I needed the diversion from the turmoil of the day. Thank you so much!

Ahh... Now it makes sense...

I misread your first post and I thought you wanted to dive in a sea below this massive amount of oxygen.

Anyway...

That would be so freaking cool !

Didn't scientists made a whole show where they showed an imaginary world. A possible scenario ( in their opinion ) what life could live out there ? It was called Blue Moon or something.

It was a planet with a very dense atmosphere and it was home to a species that resembled whales on earth, only they swam around high up in the sky.

Well that's because the placenta feeds us our oxygen, not our lungs.

Technically I think the oxygen is transfered from the lungs of mom, by the shared blood stream. The oxygen does travel through the placenta, I think.

Nice post OP!!

I dont want to dampen the thread but purely to make aware that the diver Wes C Skiles who took some of these lovely photographs died last week in a diving accident. He was only 52.

R.I.P Mr Skiles and thank you for your lovely work and insights.

blogs.nationalgeographic.com...

Apparently TV_NATION and I were on some kind of mental wavelength connection here lol, I began compiling a report on Mexican Cenotes and discovered your post to be similar to my own, so I posted my report and added your thread link to my Report, entitled:

The Yucatan Legacy: A Legendary Underworld

This is definitely a double feature on the Yucatan Peninsula's Impact Crater's Marvelous creations!

Great post BTW - I loved every minute of it! more spots to go diving at woohoo - gotta get over to Gran Bahama Island soon !!

Well there's the strange part. Mother and fetus never share blood unless mankind damages something to make it occur. Nutrients and waste only exchange at the placenta. One can imagine it as the World Trade Center of the two, with cells being stock brokers and what not, yelling and exchanging what they want. Very active straight until birth. Demand rises, so people buy. Demand drops, so people sell. Cells bring the waste to the placenta, and the cells in the mother buy the waste for the liver. Baby's cells want oxygen, Mother's cells sell them oxygen and super low costs by getting the worker cells of the lungs to work harder for the same cost. lol. Very dynamic system between the two. Pretty much, pregnancy is the only time when the human body is able to physically adjust things outside the body without bodily motion. I could also get into what not with abortion and "personhood" but that's off topic and you can PM me on that.

Ah! Extraterrestrials! A great show back in the day. It's the initial spark for a low A, high TP planet. After the initial idea I let my dreams carry me away to worlds far off and unique and with walking squid that don't need skeletons and reptile-like-mammals with feathers. Fun times for a kid.

The planet I made was a we bit crazier where basically if you had a high power fan you could hover around and travel, breathing the atmosphere. But later on in the planet's history it had a collision event that poisoned the atmosphere with lead that only native species can now breath.


All and all it is extremely fun to look at a new world that is 3d rather than our usual 2d world with up and down. A weightless, nutrient rich water world with energy plentiful and life boundless. Earth's deep dark secrets are always cool to look at.

Only ever seen photos of the "hole" never one's
taken uner water.
outstanding. have a S & F.

Very interesting indeed -- I find that cave diving is a most fun adventure that I would love to get in to. I found this site with similiar vibe that talks about ancient advanced civilizations and how evidence for them might be hidden in underwater caves around the world:

The Conscious Connection

happy seeking my friends!

Awesome pictures! I don't have time to check this, but the info on the world record holding Free Diver; 4 minutes and a depth of almost 320ft!! Can you even do that depth in that amount of time without decompressing properly? I don't think you can honestly, but I am not sure.

Very cool TVN! I was unaware of such frontiers. Those guys are hella brave! That is one thing I do not think I could do, and I don't have claustrophobia either, it's just a level of danger I would rather avoid, but I'm glad someone is bringing it to us. Beautiful photos and nice find!

Wow what a fantastic thread! Thanks for taking the time to create it.
The pictures are absolutely fantastic.

Is there anywhere our trash doesn't end up? It's sickens me to see tires down there.

Nice to see these pics, though. Interesting world we live in.

I don't post much here. I read the site EVERY day of my life, but hardly ever join in the discussion, but this thread made me stick my head out to say *thanks* for posting these awesome pictures and captions.

Kudos, and a rarely given (from me) star and flag.
