Deep sea physics: Water pressure and the incredible shrinking head
 
00:32
To illustrate the effect of water pressure on air spaces in the deep sea, a styrofoam head was carried by a submarine, from the surface down into the ocean to 3,000 meters (9,840 feet). Water pressure increases with depth, compressing the tiny air pockets in the styrofoam, and causing the head to shrink. At a depth of 3,000 meters, the pressure is 300 times that on the surface, and presses about 4,400 pounds on every square inch of the head. It would feel like having a 4,400-pound adult hippopotamus sitting on your thumb! Because water is less compressible than air, deep-sea animals often have hydrostatic skeletons (skeletons that are supported by fluid pressure) and lack air spaces in their bodies. Deep-diving mammals, such as elephant seals, have adapted to the immense pressure in the deep waters where they hunt, by having collapsible lungs that press out all the air as they are diving down to depths of up to 2,000 meters!

Whatever you need a website for, create yours today with Wix: https://www.wix.com/go/infographics What is the deepest submarines can go? Can submarines reach Mariana Trench? Can submarines go even deeper than that? On January 23, 1960, the Trieste touched down on the sandy soil at the bottom of Challenger Deep, the deepest part of the Mariana trench and deepest point in the world. At a depth of 35,815 feet (10,916 meters), the Trieste withstood an incredible 1.25 metric tons per square centimeter of pressure, although the single plexiglass window had cracked on the way down, giving American Don Walsh and Frenchman Jacques Piccard a good scare. Yet the Trieste was not a submarine, but rather a bathyscaphe, specifically designed to withstand the tremendous pressure. In today’s episode of the The Infographics Show, we ask, how deep can submarines go?

Crazy DANGERS Of Deep Sea Diving
 
09:50
Of course, there are a ton of reasons to go for an adventure far under the surface of the ocean, but do you know all of the potential risks that accompany each and every dive? If you didn’t, here they are, these are the 15 Dangers Of Deep Sea Diving. #7 - Nitrogen Narcosis Nitrogen Narcosis is yet another serious issue divers need to be aware of. When the human body gets too much nitrogen in their system, it creates a kind of narcotic effect. It would feel like the nitrous-oxide gas given to you at the dentist’s office. While you might enjoy that woozy feeling when you’re inside a dentist’s office on dry land, this is not a feeling you would want to experience when you are far under water. Nitrogen narcosis damages both sensory perception and judgment making each decision the affected diver makes a potentially dire one. #6 - Gaps In Actual Experience If you are an experienced diver, you know that there is a rule that states you have to take a refresher course every six months that you haven’t been actively diving. Although you, being a diver, might laugh because you believe that the course really isn’t all that big of a deal, it really is very important. After not diving for just a few months, some of the very minor but incredibly important and vital details of the preparation or procedure of diving could be forgotten. Depending on which part you forget, that tiny sliver of information might just cost you your life. Just take the refresher course to get back in the loop. #5 - Losing Your “Buddy” It might seem silly but the “Buddy System” is really important when it comes to dives and swimming out in the ocean. If you have a buddy, there should always be at least one other person in the water that is concerned with your safety and survival. The ocean is not a place to lose your buddy. #4 - “The Bends” Decompression sickness is most often referred to as “the bends” and it is caused by increased pressure which makes the tissues in a body absorb more nitrogen. When that fierce pressure is suddenly reduced, the extra nitrogen can form tiny nitrogen bubbles that can kill. When deep sea divers want to return to the ocean’s surface, they must do so in distinct stages that are carefully monitored so that they can best control the rate of which the absorbed nitrogen is released. The bends can range from the affected having aching joints, a creepy skin rash, or paralysis and even possibly death. Do NOT go diving without being properly trained. It is not a hobby that you can just pick up an afternoon. #3 - Not Wearing Adequate Protection We aren’t just talking about wearing durable gloves while checking out a sunken shipwreck, although if you do get cut without wearing protective gloves, you can get tetanus, which doesn’t sound like fun. We’re talking about wearing gear that is suited to the climate and temperatures of the weather and the ocean you are diving into. When you are wearing a short wetsuit, don’t go play around in some coral where you can easily get cut up, which could lead to even more danger. Also, the temperature of the water gets colder the further down you get, so make sure you dress appropriately, it’s not like you can just put on a jacket once you’re underwater. #2 - Oxygen Toxicity Oxygen toxicity happens only when the person is deep sea diving and goes more than 135 feet below the surface. Just like nitrogen, which caused a lot of problems for divers earlier, the body absorbs more oxygen when the body finds itself underneath increased water pressure. Experienced divers know how to deal with the increase of oxygen but as the pressure and depth increase, the body absorbs more and more oxygen and too much can become toxic. The symptoms start with tunnel vision and nausea and then switch to loss of consciousness and seizures. If either one of the last things happens while you’re underwater, you’re most likely never making it to the surface again. #1 - Mask Squeeze The woman in this picture looks like she is about to start bleeding from her eyeballs which is a rather frightening thing to see. However, she isn’t a lead role in an up and coming horror film, she’s suffering from a diver’s condition called “mask squeeze.” When the pressure of the air inside the mask isn’t equalized correctly, the outside pressure causes the scuba mask to be pushed on the diver’s face resulting in this scary painful look. The small blood vessels surrounding and in the eyes burst, which leads to the bloody eyeballs you see here. This is not the look she was going for, we’re sure of that.

The deep ocean is the final frontier on planet Earth | The Economist

Watch the latest in the Ocean series - Secrets of the deep: https://youtu.be/Zwgtn41TpfU The ocean covers 70% of our planet. The deep-sea floor is a realm that is largely unexplored, but cutting-edge technology is enabling a new generation of aquanauts to go deeper than ever before. Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7 Beneath the waves is a mysterious world that takes up to 95% of Earth's living space. Only three people have ever reached the bottom of the deepest part of the ocean. The deep is a world without sunlight, of freezing temperatures, and immense pressure. It's remained largely unexplored until now. Cutting-edge technology is enabling a new generation of aquanauts to explore deeper than ever before. They are opening up a whole new world of potential benefits to humanity. The risks are great, but the rewards could be greater. From a vast wealth of resources to clues about the origins of life, the race is on to the final frontier The Okeanos Explorer, the American government state-of-the-art vessel, designed for every type of deep ocean exploration from discovering new species to investigating shipwrecks. On board, engineers and scientists come together to answer questions about the origins of life and human history. Today the Okeanos is on a mission to investigate the wreck of a World War one submarine. Engineer Bobby Moore is part of a team who has developed the technology for this type of mission. The “deep discover”, a remote operating vehicle is equipped with 20 powerful LED lights and designed to withstand the huge pressure four miles down. Equivalent to 50 jumbo jets stacked on top of a person While the crew of the Okeanos send robots to investigate the deep, some of their fellow scientists prefer a more hands-on approach. Doctor Greg stone is a world leading marine biologist with over 8,000 hours under the sea. He has been exploring the abyss in person for 30 years. The technology opening up the deep is also opening up opportunity. Not just to witness the diversity of life but to glimpse vast amounts of rare mineral resources. Some of the world's most valuable metals can be found deep under the waves. A discovery that has begun to pique the interest of the global mining industry. The boldest of mining companies are heading to the deep drawn by the allure of a new Gold Rush. But to exploit it they're also beating a path to another strange new world. In an industrial estate in the north of England, SMD is one of the world's leading manufacturers of remote underwater equipment. The industrial technology the company has developed has made mining possible several kilometers beneath the ocean surface. With an estimated 150 trillion dollars’ worth of gold alone, deep-sea mining has the potential to transform the global economy. With so much still to discover, mining in the deep ocean could have unknowable impact. It's not just life today that may need protecting; reaching the deep ocean might just allow researchers to answer some truly fundamental questions. Hydrothermal vents, hot springs on the ocean floor, are cracks in the Earth's crust. Some claim they could help scientists glimpse the origins of life itself. We might still be years away from unlocking the mysteries of the deep. Even with the latest technology, this kind of exploration is always challenging. As the crew of the Okeanos comes to terms with a scale of the challenge and the opportunity that lies beneath, what they and others discover could transform humanity's understanding of how to protect the ocean. It's the most hostile environment on earth, but the keys to our future may lie in the deep.

Scuba Diving for Beginners - Understanding Atmospheres Underwater is Easy
 
03:03
Learning about atmospheres underwater is easy! This short motion graphic explains the basics of pressure, density and volume underwater while diving. Learn more about diving at: chrisbrockscuba.com Audio Script: Think about it. Your lungs are balloons. When you breathe in, your lungs inflate, and when you breath out, your lungs deflate. So what would happen if you held your breath while scuba diving? If you held your breath while descending, your lungs will become smaller – creating dense pressure inside your full lungs. If you held your breath as you ascended, the air in your lungs would increase in size under pressure. In either scenario, eventually your lungs would fail. This is why the number 1 rule of scuba diving is NEVER HOLD YOUR BREATH! So, you might be thinking – why does pressure change underwater? It’s simple. The deeper you dive, the higher atmosphere you’re in. When diving into a higher atmosphere, the volume of air spaces will get smaller, and the molecules in those spaces will become more compact. The term atmosphere is simply a unit to measure ambient pressure. Since water is denser than air, greater changes in ambient pressure occur underwater. Every 33 feet of depth adds another atmosphere to the ambient pressure. Once you understand atmospheres you can calculate your own air consumption at a given pressure, helping you plan your dives efficiently and accurately. As a recreational scuba diver, you are trained to dive safely between 1 and 5 atmospheres. At sea level you start your dive at 1 and as you descend deeper underwater, the pressure and density increases – and the volume decreases. This relationship between pressure, density and volume stays consistent as you dive. At 33 feet deep you’re at 2 atmospheres. At this depth, volume is 1/2 of what it was on the surface and the density is 2 times denser. This relationship continues as you dive deeper – all the way down to 132 feet where at 5 atmospheres the volume is 1/5 of what it was on the surface and the density is 5 times denser. Make sense? Think about it this way. If you had a balloon at the surface with a volume of 10 units, taking it down to 5 atmospheres, would reduce the balloon’s volume to 2 units – because at 132 feet, the volume of an object is 1/5 of what it was on the surface.

Water Pressure Depends Only on Depth, Not Container Shape
 
14:57
The pressure of water at rest in a container depends only on the depth, not the shape of the container. For each additional 10 cm of depth, the pressure increases by 1 kPa (kiloPascal). This means that the pressure is a constant at a given depth, irrespective of the size and shape of the container. This basic principle of hydrostatics might at first seem to be counter-intuitive. It certainly does not apply to solid objects, like blocks of wood. The difference is that a liquid has no shear strength -- water cannot be bent or twisted. Instead, it transmits forces uniformly in all directions. Water poured into any container, of any shape, quickly flows to the bottom and arranges itself with uniformly decreasing pressure from bottom to top. If you draw a "topo map" of pressure (viewed from the side of the container), the lines of constant pressure are always uniformly spaced horizontal lines, for any container shape. The reason is that water exerts a force perpendicular to the container wall, exactly the same as it would against an equivalent shape and volume of water. Thus, any container wall, of any shape or direction, behaves just like an equivalent amount of water. The water "doesn't care" whether it's meeting a wall or more water. It's all the same to the water. So as far as water pressure is concerned, a weird and twisting container is just the same as a rectangular container with parallel vertical sides. The force of water on the bottom of a container can exceed the weight of all the water in the container. To understand how this is possible, watch the last third of the video presentation, which uses an upside-down T-shaped container as an example, or see the separate video at https://youtu.be/JkhufvEHGLc More science videos: Electric Circuits and the Hydraulic Analogy https://www.youtube.com/playlist?list=PLaqfpQcOfMt6K5A2CauGxL5Y75hzld7-D

Ocean bottom pressure from GRACE
 
00:37
The twin Gravity Recovery and Climate Experiment (GRACE) satellites, launched on March 17, 2002, have been making detailed measurements of Earth’s gravity field from space and revolutionizing investigations about Earth's ocean, water reservoirs, large-scale solid Earth changes, and ice cover. To aid in the interpretation of gravity change over the oceans, the GRACE Tellus project provides ocean bottom pressure maps derived from the GRACE satellite data. Ocean bottom pressure is the sum of the mass of the atmosphere and ocean in a "cylinder" above the seafloor. This visualization shows monthly changes in ocean bottom pressure data obtained by the GRACE satellites from November 2002 to January 2012. Purple and blue shades indicate regions with relatively low ocean bottom pressure, while red and white shades indicate regions with relatively high ocean bottom pressure. Scientists use these data to observe and monitor changes in deep ocean currents, which transport water and energy around the globe.

How to Equalize Ear Pressure using the Valsalva Maneuver while SCUBA diving
 
06:21
Download our free guide “The Four Keys to mastering your Diving.” http://greatdivers.com/yt/equalize For more information about equalization techniques visit our blog post on the subject: https://greatdivers.com/preventing-scuba-diving-ear-problems How to Equalize Ear Pressure for SCUBA Diving Why do my ears hurt underwater? As we descend into underwater, the pressure surrounding us increases. That rise in pressure causes our ear drums to compress. This happens because the water pressure outside of our ear is greater than the air pressure inside of our ear. Equalization is the procedure divers use to equalize the air pressure in our inner ear to the pressure outside of our ear. We do this by pushing air from our sinuses to our inner ear through the Eustachian Tube. When to equalize when SCUBA diving? Equalization occurs early and often. Before you break the surface and begin your descent, you should begin to equalize. You should equalize every couple of feet as you descend in the water column. If you do not equalize early and often, your eardrum can compress causing pain. The pressure can even close your Eustachian Tube. This is known as the “trapdoor effect” and can be avoided by equalizing early and often as you descend One good tip to follow is if you feel pain in your ears, you have descended too far without equalizing. In the event that your feel pressure in your ears, stop your descent and ascend a few feet until the pain goes away and then try to equalize. You should never equalize on ascent. The air in your ear needs to escape as the surrounding pressure decreases. Because of this, there is no need to add more air to your inner ear on ascent. How to equalize underwater There are several different ear equalization techniques you can use to relieve ear pressure. Which one you decide to use or works for you depends on your physiology, how your sinuses are functioning on the day you are equalizing and preference. The most common method of equalization is called the Valsalva maneuver. This is probably the one that you were taught in your dive class. You perform the Valsalva Maneuver by pinching your nose and gently pushing air to the back of your throat through the Eustachian tubes and into your inner ear. While you do not want to blow too hard, you do need to apply enough force to feel your ears filling with air. If the Valsalva maneuver does not work, do not worry! There are several ear equalization techniques you can use. Turning your head from one side or another while performing the Maneuver help Swallowing while doing the Valsalva A combination of the above. Tilting you head back while attempting the Valsalva Wiggling your jaw forward while trying the Valsalva The Toynbee Maneuver and can be used. You perform the Toynbee maneuver by swallowing with your mouth closed and your nose pinched. You do not have to blow out while doing this The Frenzel Maneuver is another alternative. It is performed by pinching your nose while pressing your tongue against the back of your throat while making a T or D sound. What if I still Can't Equalize Pressure?? Below are a few tips you can use to assist your equalization. Descending feet first: If you have trouble equalizing, try descending feet-first rather than doing a head-first descent. This reduces the change in surrounding pressure drastically. Descending on a line: If you’re still having difficulty equalizing, you can control your descent even further by descending on a line feet-first. Chewing gum before your dive: This relaxes your soft palate which has been known to assist in equalization. That being said, YOU CANNOT chew gum during your dive. This could cause a dangerous situation, so do not do it! A few of things to remember: Equalize right before you begin your descent and continually all the way down to your destination. Remember that we never equalize while ascending. If you feel pain in your ears on descent, stop and ascend until the pain goes away before attempting to equalize. Remember to try descending feet-first if you are having difficulty equalizing Do not dive when you are congested. Practice several methods of equalization Remember that practice makes perfect.

What Happens If You Dive Too Deep?
 
05:03
Deep sea diving is very fun. The excitement increases as you go deeper and deeper into the sea. However, there are depths at which your body cannot handle. Pushing beyond this point may result to serious health risks on your body. As you dive deep into the sea, the pressure underwater increases. Your body responds by increasing pressure inside your body to try and match with the pressure outside. The lungs will shrink to try and conserve oxygen in your body, since air supply underwater is very low. Blood will be concentrated in your heart and brain, as these are the areas they will be needed the most. When you reach the depth limit, your body will not be able to withstand the tough conditions. You will start to experience ear pains, fatigue, nose bleeds and hallucinations. In severe cases, you may experience the bends. Bibliography: Omega Divers. (2018).

How Deep Is the Ocean In Reality?
 
17:26
A whopping 94% of all life-forms on Earth are aquatic. Such a huge number of living beings who can't survive without water is understandable. After all, more than 70% of our planet's surface is covered with water. The World Ocean includes the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean. There's enough water in the oceans to fill a 685-mile-long bathtub! One of the main nagging questions people have been asking for ages is "How deep is the ocean in reality?" Let’s find an answer to it. #marianatrench #deepplace #deepocean TIMESTAMPS Sunlit zone 1:21 Twilight zone 6:17 Midnight zone 10:19 The abyss 13:17 Trench zone 14:25 Music: https://www.youtube.com/audiolibrary/music SUMMARY -The Sunlit zone stretches from 14.5 ft, that is is the depth of a standard Olympic diving pool, to 561 ft under the water’s surface, where RMS Carpathia found her last dwelling. This ship became famous after her participation in the rescue of the Titanic survivors. -At 656 ft, the twilight zone begins. That's where you can see the giant oarfish. At a depth of 1,453 ft, you could reach the height of the Empire State Building if somebody powerful enough decided to submerge it under the water. The giant squid lives as deep as 2,952 ft below the surface. This is where the Twilight zone ends. -At a depth of 3,608 ft, there's the deepest volcano recorded by scientists. At 12,795 ft below the water’s surface, there are Air France flight 447 black boxes. Airbus A330 crashed into the Atlantic Ocean in 2009. This is where the Midnight zone ends. -At a depth of 13,123 ft, the midnight zone ends, and the abyss lies ahead. 18,897 ft is the bottom of the abyss and the depth at which you can find the deepest shipwreck. SS Rio Grande sunk in 1941 in the South Atlantic and was discovered only in 1996. -At a depth of 19,685 ft, the abyss ends and gives way to the trench zone. At a depth of 36,070 ft, you will reach the very bottom of the ocean in its deepest point known to man: Challenger Deep.

Who Lives In the Deepest Place On Earth?
 
09:57
Who lives at the bottom of the Mariana trench? Scientists have finally revealed the Mariana Trench mystery. Take a look at the deepest creature ever caught there! The curiosity of human nature makes people look for secrets and mysteries far away from home, like in outer space or on other planets. Scientists have mapped only 5 percent of our planet’s seafloor. And if you’ve ever considered the ocean plain and boring, the video you’re about to watch will blow your mind. TIMESTAMPS The Mariana Trench is the deepest area 0:45 The deepest-living fish in the world 2:40 “Ethereal snailfish” 3:12 A mysterious metallic sound 3:38 Deep sea cucumber 5:50 The deep sea anglerfish 6:20 The barreleye fish 7:13 The Champagne Vent 8:05 The 4-inch amoeba 8:35 SUMMARY The Mariana Trench is the deepest area you can find on Earth. Although almost everybody has heard the name, we have shockingly little data about this dark underwater place in the western Pacific Ocean. It’s a monumental task mapping the seafloor and taking pictures when the water pressure at the bottom is more than 1,000 times greater than that at the surface!

Curious and Unusual Deaths: Death Under Pressure
 
21:32
Death Under Pressure In New Jersey, a teenage girl drowns when she gets caught underwater in the intake valve of a hot tub. On an oil platform in the North Sea, a group of deep sea divers die of explosive decompression when a clamp on a diving bell fails. In England, a man dies of a ripped blood vessel after a very powerful sneeze. This is a scientific investigation of case studies where death has come from unexpected means. The viewer will invest themselves into the story and the science without simply waiting for the next gruesome grizzly scene. And for these reasons Curious and Unusual Deaths will never feature any deaths involving children pets or suicides. Curious and Unusual Deaths is a romp through the world's weirdest fatalities - and the scientific story behind each one. It's the science that kills when death shows no mercy.

Teach Astronomy - Extreme Pressure Environments
 
00:56
http://www.teachastronomy.com/ There is a set of organisms that can persist and thrive under conditions of extreme pressures. They are called barophiles. Barophiles can exist at pressures of hundreds of atmospheres. These environments are typically found in the deep sea. For example, there are entire colonies of eukaryotes on the continental shelf. Sea cucumbers and other creatures also exist under very high pressure, and there are microorganisms that thrive near deep sea black smokers. At the other extreme many organisms can do well at conditions of low pressure or high altitude on the Earth's surface. At the top of the highest mountains there are algae, plants, even insects, and in laboratory experiments certain insects have survived at pressures less than one-tenth of the pressure at sea level.
