I’m more afraid of the depth, and what plant life is down there. For example, seaweed, or kelp. It creeps me out. In Washington, Puget sound, around 6 feet deep there is seaweed. I’m too scared to swim, so I just stay on a water trampoline. Rip,
This is not a submarine, the frequency and consistency of the pings are approximately 237.98701 htz/s and judging by the time between each ping the “submarine” is exactly 2.394 nmi and this would mean that the “sub” would only be about 3.2 m in length and made of aluminum therefore it is not a submarine, but instead a Fortnite supply drop
It's his dive computer Mr. Wizard and you can't tell submerged displacement from a recieved sound. Oh, and by the way, your formula doesnt work either..
I was a Sonar Technician in the U.S. Navy and I'm telling you that is not a sonar transmission from a submarine. It's either from a diver computer (most likely) or possibly a nearby charter boat with a fish finder (much less likely). It is absolutely, definitely not a transmission from a submarine or surface warfare vessel. Wrong frequency, wrong duration, and wrong intensity. Also, the fact that the pitch remains constant indicates that the range is fixed. Given that you are staying close together and you aren't hearing any engine noise from a trolling charter boat, I'm positive that it's your dive computer or that of one of your dive buddies. And before you say the inevitable "You don't know every sonar in the world", let me stop you right away. Yes, I do. It was my job to know the machinery and sonar frequencies of every class of warfare vessels and common merchant shipping worldwide. So yes, I do know every sonar "ping" in the world. (Oh, and we don't call them "ping". That's just Hollywood)
I dove on the edge of a drop off like that years ago. It’s actually pretty intimidating. One minute you’re skimming the bottom and then suddenly the bottom just disappears from under you. The thing I remember best is the water suddenly turning very cold. Interesting experience!
Abyssal oceanic drop offs are VERY dangerous for that and the fact that large predatory sharks like to hang out in those areas. They’re also dangerous in that they’re prone to strong down currents that swallow you into the abyss and not being able to swim back up that shelf break/wall.
The beach house my family had years back had a beach and not too far out into the ocean it went from perfect clear blue green water to pitch black. I am starting to wonder how deep it was.
@@MisterRorschach90 Was this on an island or continent? If it’s a continent, then chances are, that the oceanic abyssal drop offs like miles away from shore and would take you an hour to get to it by boat. If it’s on an island? then the oceanic abyssal drop offs are as close as 100 ft from the beach you’re relaxing on. Islands have no continental slopes so you’re at a good high risk of being trapped into an underwater current that swallows you into the abyss.
@WeirdWideWeb Down currents are scary that’s for sure. Down currents are very common especially abyssal drop offs off islands like Hawaii, Grand Caymen, Mariana Islands, Bermuda, Bahamas etc. Also, the deeper the drop off is? the stronger the down current is. So if you’re near a drop off that drops off to 3,000 ft to 15,000 ft? You could be experiencing a very very strong down current. It’s basically an invisible waterfall underwater. It’s why you NEVER dive alone because it’s not the dangerous animals that you have to worry about when you’re diving alone, but more so the currents, getting lost, not knowing your dive depth, and the risk of running low on oxygen.
Coop4447. No it is not a person sucking. The air out of the divers tanks. It is actually a newly discovered sea creature called the Oxy leach. The Oxy leach uses sonar to locate oxygen filled air bubbles. In the water.
The Great Santini Military submarines don’t have windows. They don’t move around the ocean by pinging with active sonar. If you continue to think so, then you are out of your depth, pun intended.
who ever is in front right (lady?) needs to calm the fuck down with their breathing the guy in the middle that gave ok is obviously the dive master/instructor
Subs don't frequently ping. That gives their position away. The only time they might transmit is for maintenance, calibration, testing, or maybe during a firing exercise. When they do transmit, it would likely be on a restricted test range far away from people and general marine surface traffic.
CoolSpace where do you get your facts from.... all subs send a ping it's called sonar..... they do it 24/7 and the only time they turn it off is when they need to go dark/effcon red to avoid detection by another sub.or even a sub hunter aircraft or vessel
Look up the difference between passive and active sonar. Yes, they listen all the time, but the OP is 100% correct - active pinging is a dead giveaway. And can be very powerful and disruptive to marine life. Low power active devices (voice comms, fish finders, depth sounder for example) are a different story and not what was being discussed by the OP. Hollywood tends to instantly overlay the sound of pinging on all scenes involving a submarine, which means everybody equates submarine sonar with active pinging. Not all sonar pings occur in the human audible range either.
I heard a similar sound once when I was diving, It was incredible loud. It took me a second to stay calm when my ears were ringing from the sweep. You just don't expect that, when there is the sound of silence around you... With just some calm water noises.
That's from the boat you left from. It's kinda like a fish finder but for tracking novice divers. The crew is making sure nobody is in distress by going to deep. Basically a diver tracker. You can hear it because it's a very strong wave. They are not looking for a law suit. I heard the same thing when I was out with my diving class getting my diver certification.
Definitely. Probably a short range positioning beacon. Lower frequency = more energy. More energy is required to travel longer distance then return after reflecting.
That isn't a sub, that is my ring tone. I was diving there about a week before, and my cell phone fell out of the BCD; I was calling it to find out where it was.
American submarines don’t navigate with active sonar. They use passive. Be it American or not, that’s definitely some sort of under water resonance equipment. Food for though, active sonar could kill someone in close proximity
yo boi jonx Depends upon the type: Passive or Active Sonar. But you can hear Active Pinging. Hopefully, bc you're the Sonar Operator and not close to said Ping-Source, nor underwater. That would, in a few words, suck really bad.
Its called constructive criticism "my dude". ive held my open water diving license for many years. and this man could be getting FAR more out of his tank if he listens to me
Breathing is as much a mental trick, as it is necessity. Surly your navy training informed you that short sharp breaths are actually more than sustainable during dives, and that a calm mental state will allow you to withstand any mental desire to do as you say and breath normally. If you have a timed dive, or you dont care about how long you stay under, then yes you are completely correct. If you are trying to elongate the dive to its maximum potential that certainly is not the way. I was once recreational diving. At the VERY end of the dive we saw a humpback whale. Only the people that had regulated the breathing throughout had the oxygen to stay with it. everyone else had to go back to the boat. you never know when its helpful is what im saying.
Swimming a way off the Scottish coast one time (snorkelling, diving) got the chance to observe a Russian nuclear submarine pass under me. The sound, the size, the 'percieved' water forces (even at distance), the speed! Scariest experience I've had in the water. Though, I've spoken to fishermen who talked about snagging their fishing nets on a passing military sub (and having to rush to cut the line before the boat is dragged down). Those stories, consoled me :)
If it was close enough to be visible while using its sonar, the sound would rip through your bones, shaking your organs and brain to red pulp in the process.
Hah, I was seconds away from adding this comment before I saw it xD "Thats alright Mr. Ryan, my Morse is so rusty I could be sending him dimensions on playmate of the month"
Sounds like a fathometer, measures depth below the ship or sub. Plus, from my time in service I know that ship/submarine sonar is longer and more drawn out(and would hurt you at to close range). Plus submarines use active pinging, they ping once and listen, only for target acquisition, even then, they can still use passive sonar to accomplish the task. Which is the preferred technique.
If someone wants to take the time to look at the frequency that ping is coming out at you could google what system use it. It’s not from a submarine I can tell you that (I used to work on one 😋). The likelihood is it’s a Fathometer (bottom depth reader) from a near by boat. The other possibility is it from a research unit that’s installed in the area. A fun note is sound move 4 times fast in water then it dose in air... so that ping could be vary far away.
Serving on a sub I can tell you that you will know a sub sonar when you hear it. There is a dive video if you search that shows a sonar from a real sub.
Okay, first off that’s cool as hell, but that depth absolutely terrifies me (as off it would just suck you into with some vortex or something); and secondly, I literally found it hard to breathe while watching this video. Great video!
There's excellent diving in Barbados which hase a drop off like this. You become focused on it and it keeps drawing you closer like the edge of a tall building. What's also different is when I was a NOAA diver we had to do a qualifying dive at least once/month. Sometimes at sea for over a month so the ship would stop mid ocean and we would go in. Bottom is thousands feet down and in the middle of the ocean water is very clear and it just feels like your falling from an airplane. And that's what I be got to say about that. I think you can go back and edit to stop corrections
I remember boogie boarding once and my gran kept pressuring me to go further back in the sea, I felt mr foot slip and then my other foot slipped and all that was above water was my head, I had one of those feelings that you just know something was wrong. I could feeling nothing below my feet and being 11 years old at the time, it was an still is the scariest experience I’ve ever had.
Active sonar can reach sound up to 210dB. I personally identified these as a dolphin. They're not just "pining" you can hear them cracking as-well. Also im not an expert I just have great ears.
The problem is Devil runs the world. He is lier and murderer. That's why we've got the Gospel about the God's kingdom. Jehovah would put everything in order. The dead will be resurected and we'll meet our beloved ones again! :-)
1:22 and 0:27-0:28 are the starts of two pings - they last a good solid second or two, and then there's a little, quick, high-pitched "chirp". So I don't think it's the chirp the video is referring to. Hard to hear over all the breathing. I know you're not supposed to hold your breath on a dive, but...
Macin toshiba Lol! I was just thinking it's uncanny how perfectly it matched that game! I think the game may have just gotten it right, though. I wonder why it sounds like that? Now I'm curious... Hopefully it's nothing the DoD minds people asking, hah. Not like everyone doesn't know how to build active sonar already.
ViperKing 84 does that even sound different? I don't see why, unless one uses LF and the other uses MF or something. Unless you mean in the game? I mean, that's what it is in the game, too. That's why some ships will sound different. Notice the active sensor that's listed on the contact tab.
Sounds like SQS-53C for me. But either they are pinging with very low power, it's tens or even hundreds of Kilometers away or they do directional ping. Because you can faintly hear FM sweep (Frequency Modulation, that first iconic sweep) And after the sweep you can hear that very unique chirp which is omnidirectional (that's the reason why you hear it louder than the first sweep) I ain't sonar tech but i'm a Ham radio operator and i can tell you that sonar works like a radar but without the radiowaves since water blocks most of the rf but carries the sound much better.
I am an Ex-sonar ping and I can confirm that this was not in fact a ping but a underwater band of mermaids wanting to trade gold for your spare Ketchup packets
most likely a surface ships sonar. just a guess though. served in the navy as a sonar tech. also judging by the noise level it's pretty far away as well. under the right conditions the sound from an active sonar ping can travel for hundreds of miles.
Dude, you are going thru that tank fast. Slow controlled breathing is needed here. I dove with a buddy that did this. He was out of air climbing back into the boat and I still had 1800 psi in my tank.
As a certified cave/tactical diver, what you say is true, but it’s not that simple. If somebody is fat, out of shape, or a smoker, and their body otherwise needs more air due to absorbing less oxygen in their lungs… you can’t just say “hey, breathe less!”, lmao. They need the air
They should definitely work on improving fitness, exercising a lot more, losing weight, quitting smoking and drinking, and things like that, to try to get stronger lungs and healthier body so they need less air underwater… BUT, IN THE MOMENT, there’s not much they can do
I mean yeah, if they calm down emotionally and if they use much slower, more controlled movements, they can reduce their breathing a small amount. But ultimately, some fat guy is going to need more air than Michael Phelps if he decided to go scuba diving. Get my drift?
Wrong frequency for fatho. Also, the pitch remains constant so unless the ship is anchored and within about 100kyds, no. The fact that the pitch remains constant indicates that the range is constant. It's a dive computer on one of his buddies if not his own. He probably knows it's a dive computer but wants the attention from people who watch movies and base their intel on Hunt for Red October instead of reality.
+Victor Roxburgh It's the high pitched Sine-like wave beep. It's pretty distant and you cant hear the refractive sweeps or any of the artifacts that you'd find with most sonar recordings when a sub is close.
Submarines do not typically use ''Active Sonar'' this give away their position. Take it from a EX Submariner. Active sonar is usually used by surface vessels to ''Find'' Submarines. But that also give the submarine a direct position of the skimmer.
Skullman123 , Man you sure do got some nerve diving on that drop off . Scares the hell out of me just looking at it because there’s know telling how deep it is . Couldn’t pay me enough money to do that but I’m sure it’s a lot of fun and unseen world down there.
I've heard modern us sonar equipment kicks out more watts than your local radio station, and a full active ping will flash boil the sea water against the nose cone.
