Humanity and the Deep Ocean | James Nestor

James Nestor takes us into the ocean's depths with freedivers who go death-defyingly hundreds of feet below the surface without scuba gear. In researching it Nestor found there's much more to freediving than a thrillseeker's pastime. He details compelling insights about not only the ocean and its creatures, but about our own human senses and biology which await us in the Deep.
"Humanity and the Deep Ocean" was given on October 07, 02014 as part of The Long Now Foundation's “Conversations at The Interval” Salon Talks. These hour long talks are recorded live at The Interval, our bar, cafe, & museum in San Francisco. Since 02014 this series has presented artists, authors, entrepreneurs, scientists (and more) taking a long-term perspective on subjects like art, design, history, nature, technology, and time.

Errata: At 7:40, James Nestor misspoke. He said that that seawater has more iron and less magnesium than human blood. The opposite is true. Mg concentration in human blood is about .8-1 mmol; Mg concentration in seawater is 53mmol. Fe in human blood is about 1650-4500 nmol/L; Fe is sea water is .1 nmol/L. Nestor regrets this error.

Валентин Valentin Ya, Maybe we could change the Name we us for them or Maybe leave that term out of the vocabulary used during Communications.

Well, I watched this entire video. I bought the book. I read it quick time and I'm now beyond fascinated by the Ocean, whales, dolphins and free diving. Now, if only I could stomach up the courage to 'get wet.' To any whom may read this comment, I urge you, nay I implore you to immediately read Deep by James. It is a powerful book that grips you. I learned much that I was completely unaware of. The origins of life on earth are beneath us, in our oceans. Read Deep to discover more. You won't regret it.

All I can say is that I was born and raised in Alaska. In some remote places and in Anchorage until I was an adult. I was always comfortable with directions and had a pretty good sense of it. Now, living in the lower 48, it seems like a party trick because most people I know can't find North if you show them a compass. I always assumed it was because you just learn to read the sun and the way nature acts at certain times a day and relate that to which way things are blowing or the sun is shining therefore eliminating the other possible options and you instantly know, from doing it a million times in your life, which way is north. I also used to basically make a mental map in my head when travelling back home. It was in 3d in my brain and kind of looked like a Doom level map or something. Now with GPS and living in a major metropolitan area, I don't have to flex that muscle much. But you definitely see the lack of it in many people and that is some sort of reminder I guess. Thanks for this video! Deep ocean stuff creeps me out but I am glad I watched the entire thing!

[@mellowbear6817]

Write up the natural indicators you read and publish those writings, even if it is on the internet. I'm sure some scientist somewhere doing little to no publisized research will find it mindboggling interesting. Mind you, I find this fascinating myself.

[@adamcboyd]

@@mellowbear6817 Geez, I wouldn't know where to even put it that was useful. I mean, any Army handbook or quality survival book will have plenty of ways to tell North. I remember even learning how to do it with a sewing needle and water in a cupped leaf. It was for when you were deep in the forest and other normal indicators weren't available. When you are in a deep forest, all you see is trees. No sky or anything past a couple hundred feet. I think a lot of it has to do with the mind of the person. If you have even half of a sense of direction and go out into the wilderness, you are creating a mental map of where you have been and just applying deductive logic will get you out of a jam lots of time. But it is about crazy stuff like paying attention to the way the wind blows things down because if your back is to a hillside, or 100 other things will effect how the cottonwood is blown around. I wonder if I could do it as well in the dark without the mountains? I wonder if, since growing up in Alaska, the mountains had a big role it it. You can always tell North from snowmelt and timberlines. Really, all I am trying to say is go to Alaska before you die. It is The Last Frontier.

Cellular phones obviously are a virus!I got rid of my stupid smart phone 6 years ago. My brain woke up in a large way. Halleluyah!

[@hbamiga669]

I took a cogsci class and there is actually a lot of research into this! Your experience is likely because you are more attuned to the sun and landmarks, while people in the city are more attuned to roads and their house. Other cultures orient themselves not to North, but to a river, or the sun at any point in the sky (So "West" will be different depending on the time of day). If I could remember which cultures they were I would say, I just remember one being an aboriginal culture in Australia.

[@sharonkende4774]

And now with everyone having a cell phone with GPS, I bet people below the age of 30 can't get out of their kitchen without their phone. I mean no disrespect, it is not their fault but there are lots of advantages to growing up in a place that is removed from a lot of "advancements" in technology.

[@blubbfisch98]

This explains why I always find home I have a terrible sense of direction when I have to direct myself to new places - but you can ask me whenever you want and I will tell you exactly in which direction my home is and how I can get there. It isn't even influenced by drugs such as alcohol (although it takes quite a bit of concentration). It is something very practical when hiking. I talked about it with natives from Seychelles and they have it too although I never bothered to think about it.

I've tried to figure out why mainstream science pushes back so hard (and you will find it in all disciplines) and the only conclusion i can come up with is jealousy. Think of someone who has spent years going through the university system, then goes out into the world to either find a job or fight for grants, then a person comes along to make a revolutionary breakthrough, it's going to hurt them and make them respond unkindly whatever the evidence, it is seen over and over again which only holds not only humans back, however, even the creatures sharing this planet with us.

I have allways been convinced that there are many very intelligent creatures in the ocean, and we should be using much more resources researching how to communicate with them. Orcas are also very intelligent and absolutte apeks preditors(they eat Great whites ffs) but they don't harm humans, why? Also octopus communicate visually by changing colour. And they show many signs of intelligence. They are probably very intelligent but I reckon they use their intellect in other ways than us. Opposed thumbs and sharp vision might be part of the reason

The Yaghan people of Tierra del Fuego stood out to early European explorers when they were discovered because of their ability to resist the frigid climate. They rarely wore clothing and frequently went naked, even when swimming in freezing cold water. Somehow the cold just didn't affect them. Unfortunately, we'll never be able to find out more about them, because their population was absolutely decimated by disease, and there's only one full-blooded Yaghan individual alive today. Humans are capable of more than we think, but any time you approach the topic it's written off as superstitious nonsense. We sacrificed our connection to the world for technological progress, and I'm not sure it was worth it.

Maybe in our distant past we were sea creatures that learned to breathe air and live on land, and the sea is a return home to ancient times. Free diving is against our acquired natural breathing reflexes and one can see the reaction to panic is understandable. But what if someone less experienced and less confident was hypnotised to not panic and to control the natural instincts in a state of being airless in deep water?

- "The More Perfect Logos of Philo Judaeus ?" - - I knew my theory that people are more like Dolphins than Monkeys had something to it. And I though this up at ten . When I was a Free Dive Swimmer. My Dad was a recreational SCUBA Diver and taught me at a very young age to safely swim in the ocean . But I never took to SCUBA because it felt , the closest word is ‘ decadent ‘ to Me . I did'nt know shit about shallow Water Black - out . The feeling to exhale before reaching the surface just seemed more ' efficient' to the surfacing procedure . He's right . It all comes just as natural as breathing itself . But there is a different 'ontos' in the water. Not like a vapid minded symptom of Hypoxia , not like an empty Minded Mantra Meditation , but a clarity of Mind , and yes accelerated cognitive activity that no one has Made a word for Yet because it is beyond words , but I tell you it is not a 'rapture of the Deep . ' I probably went to fourty fifty feet at the most because that was were I felt I was to stop . This was a very good video . I'm glad to see , finally a vocabulary for the whole experience . I used to practice holding my breath in a swimming pool. This all was My summer time scene for like five yrs. I was more at home in the water. I think , back then , in the height of it I'd probably be lying in mud puddles if out of water for a whole week probably . Just from instinct to get under there , and connect to that Logos that would make any one who's been there and can "see what I mean". It would make any one of them think of 5G Band Width's information capacity more like a Medieval smoke signal 's , to use a similie. This was thirty five yrs. ago. I almost forgot this , but there were times I Remember Swimming without a Mask , just to try it , and It's not a big deal without it . I was not into going past that neutral Buoyancy point . I was Young and could not afford to buy a new weight every time. I like just snorkel Swimming. But it's all so Natural .

I saw the clip from around 30 minutes in so I decided to watch this whole lecture. I can see why they chose that particular clip, now. The rest of the lecture isn’t even a toe dip into pseudo science, it is a full blown deep dive into it. A few things he said were flat out not true, like free divers not getting the bends. It is rare but it does happen with very deep free dives that are done back to back. The fact that he says it during the clip of the French diver that is doing exactly that…come on. He seems like he likely knows that DCS can occur but knows that most of his audience won’t know and won’t bother to look it up themselves. Competitive divers and divers in the South Pacific that are spear fishing for their livelihoods are doing multiple deep free dives, not just one. That can cause the nitrogen build up. The breath you take before you go down is going to use up all the oxygen but that nitrogen is still there, and the further down you go the more it pressurizes in your lungs. Also the way he presents this kind of scares me, he’s not quite so clear on just how dangerous that style of super deep free diving really is. It’s too sugar coated in this mystical pseudoscience nonsense, and it worries me that people will listen to this lecture and attempt free diving without learning enough about the risks first.

I think my mum is the exception to the rule, as far as INNATE sense of direction is concerned, she could get lost in our very small house lol .

Spermwhales catch squid by echolocation , however !!! ... the clicks .. can paralyze squid , because they are so powerfull , it also heats the squid up ( boiling it alive as it where ) and if you warm fish up they DIE immidietly , so this may happen with squid to , and nobody has thought to connect these things

Going beyond our suns protection system is that space is denser than the space closer to the suns or even in the closer too the center of our own black hole it's lesser density as you go closer to the center of our galaxy center this is due to gravitational dynamic's. It's a projectile forces that are in spaces where it is relativity.

I have often thought more money needs to go into exploring our own planet instead of outer space after all this is where we live we take care of our own homes first.
