DEEP part of the sea where no man has gone!

I had picked up a book called "Hell's Aquarium" and it mainly talked about unexplored parts of the ocean having contain species such as the pre-historic Megadolon....this alone got me thinking a lot of about the deep parts of the ocean where man has never gone before.

Then today, in CNN there was an article about the BP gas leak and how we are using web cams to get to the very bottom end of the ocean and to my surprise, the submarines can only go to about 800 feet whereas scuba divers are at 300 feet.

Has anyone ever wondered the same thing? I would love to know more of the mysterious parts of the sea, but ...at the same time it can be scary. lol
 
The pipes those subs are at is 5,000 feet below sea level. Man has been extremely deep in the ocean.

I think the ocean and space and just life in general is absolutely amazing. I love seeing all the new things and relationships between species, etc.

The thing that amazed me the most was six foot tube worms and crabs living in 180F temps and an underwater lake.

Holly smokes, really? six foot tube worms? Wow...
 
that show "life" had an oceans episode showing life around deep-sea gas vents where temps were a couple hundre degrees and tube worms and crabs were a-plenty. Also the life under the arctic ocean. Incredible.
 
this topic really tickles me :furious:

why goto space if we havent seen our own planet fully yet ? we either have some not too smart ppl in charge or we have seen it all and dont want to tell !!! I cant find any other reason

with that in mind, I cant even imagine the life that would live down there ! for sure many new species.

I REALLY cant make sense of why we dont turn those space shuttles other way around and send them underwater instead lol

even if looking for other life, shouldnt we look deep down inside ourselves first ? u know how many new civilizations could be found under there ? (most likely not alive lol )

I saw that one as well, but the one I saw was something else and it was a series; I am about 80% certain it was another program. The whole episode of it centered around nothing but deep, deep sea.

From what I remember of the "Life" episode, they only showed maybe 10 minutes of it which is why I am led to believe what I watched was something different.:reading:

Maybe it's easier designing things to keep stuff in than out. IE: the vacuum of space versus the tremendous pressure of water.

Also... I don't think we're going to find any lost civilizations down there, but oh how I woul LOVE to be wrong!

I don't think scuba divers go down 300' without special suits on.

In basic open water certification, you become certified to 300' with out additional training or gear. Any deeper and you are supposed to get a deep water cert. Although 195' is my max depth so far and I am good with that, if I want to go deeper I think I will take a sub.

Edit: Don't pay attention to me, I guess I should not take cold medicine and play on public forums. Sorry

Discovery and NatGeo have some really cool programs with extreme depth footage. It is amazing what can live at those depths.
^^^ This part is true though

What organization did you certify with?

PADI Open Water Certification certifies to 60 feet.

PADI Advanced Open Water Certification certifies to 130 feet, and that's with Deep Water as a specialization.

300 feet for a novice diver is a long way down.

Here's a Q&A from the PADI site:

Q: How deep do you go?
A: With the necessary training and experience, the limit for recreational scuba diving is 40 metres/130 feet. Beginning scuba divers stay shallower than about 18 metres/60 feet. Although these are the limits, some of the most popular diving is no deeper than 12 metres/40 feet where the water’s warmer and the colors are brighter.

EDIT: Anything deeper than 130 feet is considered tech diving and is no longer considered recreational diving. If you were at 195 feet in regular gear, you weren't there very long.

hahaha exactly.
alot of scuba divers have STARTED to use NASA's equipments for deeper and longer dives, so I'm sure if nasa wanted to they could put a man under water too :P lol (or at least take a pic and tell us they did :P haha)

also if you believe in Ice ages and ... then at one point the deepest point underwater was a desert, so we COULD find some prehistoric fossils under there ...

MAN !!! its my dream to one day find mermaids down there LOOL haha

NASA actually trains under water in modified space/SCUBA suits to simulate zero G. I'm sure they could :)

I saw a Nat Geo special or something on a NASA training facility where they have this huge training pool with an under water space station. Pretty cool.
 
I recently did an amazing blue water dive of the coast of Kona (Big Island).

Its called pelagic magic, and was one of my most amazing dives ever.

Its a night dive about 3 miles offshore in about 3000 feet of water. The boat has lines on every corner that are 80 feet long, and you connect your BCD to them with 10 foot tethers.

At night all the deep pelagic creatures come up to feed, it is stunning. If you have ever seen the movie "The Abyss" ; James Cameron got his inspiration for the creatures in his movie from these dives, but he blew them up to a much larger scale.

I saw larval lobsters hitching rides on jellyfish, larval shrimp living inside jellyfish, larval fish, hundreds of different jellyfish, and a ton of other amazing animals. When you get out you literally have to wash the pods out of your hair.

Anyways i highly recommend this dive, its a great way to see deep water animals on a 80 foot dive.

Oh and regards to Padi Certs. Padi does not certify you to 300 feet. A Deep water certification should be taken when hitting depths of 130+ feet since this is the average depth that Nitrogen Narcosis takes place. Basic open water certs recommend no depths greater than 60 feet, but we all go deeper then that on most dives. I just have my basic open water and i will not exceed 100 feet, this is not written in stone, but a comfortable limit for me as i only have about 50 open water dives under my belt, and at 50 dives your still a beginner IMO.
 
I write taxonomic papers on some of the crustacea in deep sea sediments. Google Carpoapseudes heardi. The macroinvertebrates in deep sea sediments may be undescribed so when environmental consultants get these; there is much work to do.
