No, you don't need a certain body type to Scuba dive. Because you use flippers to SCUBA dive, you can be a very lousy swimmer and learn to SCUBA dive. You may look stupid with a very tight wet suit during scuba diving, but you can dive. When I got certified, I learned that you have a very slightly higher chance of the Bends during scuba diving, but this is a small percentage. The pros of scuba diving outweigh the cons.

What is streamlined scuba?

Streamlined scuba is just a term used for a diver who has all their gauges and equipment close to their body so they are not harming the environment around where they are diving. Commonly clips are attached to the BCD for easy access to gauges while keeping them close to your body.

What is the answer it the riddle There is a scubadiver with an empty air tank dead in the middle of the forest His body is dry and there is no water around How did he get there?

One possible answer involves a forest fire and a very charred scuba diver. During a fire a water carrying helicopter collected water from the sea in order to extinguish it. However the helicopter also picked up the scuba diver, in the sea water, and the diver was killed when he was dumped in the middle of the fire, most likely from a high altitude.

How much weights a scuba diver needs to dive in the ocean?

There are a few factors that determine how much weights you will need. You body weight and size plays an important role in identifying the amount of weights to put on your scuba weight belt. Some of your scuba gear like your wetsuit, booties etc... will make you more buoyant so you will need to compensate for this increase in buoyancy. For example, without your wetsuit, you may require only a few pounds of scuba diving weights if any at all. On the other hand, the amount of scuba weights you need with a wetsuit will vary depending upon the type and thickness of the wetsuit you will be using. A typical approximation for a cold water wetsuit is about 10% of your body weight being slightly more if you will be using a dry suit. If for example, you weight 70 kilograms, you will probably need about 7 kilograms of weight. However this should only be taken as an estimate as there are many factors which can affect your buoyancy underwater. To test if you are wearing the correct amount of scuba weights, wear all your scuba gear and enter the water too deep to stand in. Completely deflate your scuba bcd and position yourself vertically motionless in the water while holding your breath. For optimal weighting you should be floating at eye level. Exhale and if you sink slowly then you should have found your correct weight.

Can you scuba dive with a mono fin?

Monofins can have advantages in swimming efficiency for freediving. Monofins are also commonly used in underwater orienteering, a scuba based sport where fast swimming is essential. However, divers in this sport hold the scuba tank in their hands in front of them, not in a harness on their back like a recreational scuba diver. When the tank is worn on the diver's back, it interferes with the traditional monofin's function in a way that tends to negate the fin's advantages. Furthermore, a traditional monofin will induce body pitching that will sometimes result in the diver getting hit on the back of the head by the tank valve. A new type of monofin that uses a hydrofoil instead of the traditional flexible fin blade has succeeded in solving these issues and can be used with standard scuba equipment. Little to no body-pitching, and very efficient thrust production solve the monofin issues with scuba and provide advantages over bi-fins for swimming speed and reduced air consumption. See here the DOL-Fin X-15 monofin being used with scuba. See the related link for further information.

Why does a scuba diver wear a belt with varying amounts of lead weights?

We all float. Wearing a neoprene (rubber full of bubbles) wetsuit makes SCUBA divers really floaty!!!! SCUBA divers wear lead belts to counteract bouyant force (see below). If they didn't wear lead belts they would never be able to get and stay underwater. SCUBA divers have to learn the specific amount of lead weight they need to carry. Their are numerous factors that affect SCUBA divers including type of wetsuit worn (a 7mm wetsuit is a lot more floaty than a 3mm wetsuit), body mass, equipment configuration, etc. Most usually start at about 10% of their body weight but with practice, they are able to drop this to 5% and even less. From Wikipedia, the free encyclopedia The forces at work in buoyancy In physics, buoyancy (BrE IPA: /ˈbɔɪənsi/) is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter.

How do you cure or treat the bends or decompression sickness for scuba divers?

By represurising the diver to the presure that he was at then slowly normalising it. this is done in a decompresion chamber. If a decompression chamber is not used, the person will die immediatly. Do not pass go, do not collect 200$ The above is a nice basic answer. Decompression sickness results from bubbles occurring in the body after surfacing from a dive. The treatment is to recompress the diver in a recompression chamber (not a decompression chamber) to a certain pressure or depth. Different facilities use different treatment methods and therefore different depths as well as different treatment times. The pressure on the diver makes any bubbles in the body smaller and therefore easier to eliminate as well as relieving any pain the diver is experiencing from the bubbles. The diver is also given oxygen to breath since this will cause the excess inert gas in the diver (i.e. nitrogen if air was used to breath during the dive) to be eliminated faster (since nitrogen is no longer being breathed and therefore it has a pure driving force for elimination).

How does a wetsuit help to keep a diver warm?

Wetsuits slow heat loss underwater by trapping a thin layer of water against a diver's body. While the diver still gets wet, their body rapidly heats up the thin layer of water trapped against their body to nearly body temperature. If the suit fits properly, the warm layer of water does not circulate away from the diver's body. The warm layer of body temperature water conducts less heat away from the diver than the cooler surrounding water, which keeps the diver warmer than they otherwise would be.

Why would be a bad idea for a scuba diver to surface from the depth of the waterholding their breath?

It is not safe to hold your breath while surfacing from scuba diving because of the change of atmospheric pressure as your depth shallows. Holding your breath could cause severe damage to your body and could be fatal. Atmospheric pressure increases the deeper underwater you go, compressing the air in your system. So, as you surface - that air will expand. Decompression stops are part of safe scuba diving practices. This allows the air within the lungs and body to slowly expand and readjust to the decreasing pressure from a dive. Even in the event of an emergency ascent, a diver should not hold their breath but slowly exhale as they surface - exhausting all the air in their lungs by the time they surface. Should the diver surface from depth without exhaling, the air in the lungs will expand and can cause sever damage to the point of a lung (or both lungs) rupturing.

If a person is scuba diving and suffers a fatal heart attack will the body float up to the surface or sink to the bottom of the ocean?

If you are scuba diving and then suffered from a heart attack, initially your body would sink to the bottom due to the diving equipment, the weighted belt, and other items. After death as your body starts to decompose it would bloat, filling up with gases, and depending upon how heavy the equipment and the weight belt that you were wearing, this would most likely cause your body to float partway to the surface, or fully to the surface depnding upon if the gases released by your decomposing body are sufficent enough to counteract the weight of any and all scuba equipment you are wearing or carrying.

How can people die using nitrogen when scuba diving?

They can die because of the Bends, nitrogen narcosis, and the other risks of scuba diving. I'm not fully sure, because I am only basically certified and not nitrox certified. Nitrogen is actually not "used" in scuba diving, it is a natural element of air. The problem with nitrogen is it dissolves into tissues at depths which can cause the problems which can lead to the death of a diver. Excessive nitrogen dissolved into the divers tissues at depth can cause Nitrogen Narcosis which is kind of like a drunken state for the diver. The diver can experience paranoia, overconfidence, disorientation, etc. As the diver surfaces from depth, the nitrogen that was dissolved into the body is released. This nitrogen is managed by controlling the ascent of the diver and allowing it to work it's way slowly out of the divers system and expelled with exhalation. If a diver surfaces too fast he is unable to expel the gas slowly and it forms bubbles in his blood stream, a problem commonly known as the Bends or DCS (Decompression sickness). In order to help avoid these problems, deep divers use something called mixed gasses, most commonly Trimix (Oxygen, Nitrogen, and Helium) or Heliox (helium and oxygen) to lower the amount of nitrogen absorbed into the body and reducing the risk of nitrogen based problems.

How does a scuba diver suit help protect them from the ocean?

It keeps the body temperature close to normal, or attempts to do this. It also protects against coral abrasions and various other exposure to underwater animals or obstacles. Wetsuits are referred to as "exposure suits" in the diving industry.

Why do divers use weight belts?

The human body is naturally positively bouyant, as is much of the gear that a diver wears. Wearing a weight belt (which is basically just a nylon belt with lead weights on it) gives a diver the necessary negative bouyancy to overcome that positive bouyancy. A diver without a weight belt would not be able to swim down more than 2-3 feet, and would constantly pop back up the surface. Some divers actually have 'weight integrated' systems, rather than using separate stand alone weight belts. But the basic concept is still the same.

What happens to a scuba diver as they go deeper under water?

The deeper the diver goes, the greater the pressure exerted on the diver's body. This results in a number of things:the diver will consume their air supply at a faster rate *the diver's body will absorb nitrogen at a greater rate, reducing their no decompression time (or increasing the length of decompression stops they need to perform before safely returning to the surface) **they will begin to experience nitrogen narcosis, usually at about a depth of 100 feet +if they go deep enough, the oxygen content in their gas will present a toxicity risk, limiting the length of time they can stay down *** In all these examples, I have assumed our diver is breathing air on open circuit scuba. If the diver was using a rebreather, greater depth normally does not affect their gas supply (because it is recycled).** Some of these effects can be offset by using different gas mixes. For example, breathing nitrox (oxygen enriched air) will help mitigate decompression penalties, although it would worsen any oxygen toxicity penalties.+ Using gases containing a helium mix would reduce nitrogen narcosis.

What does it mean when divers watches say they are 'pressurised to three atmospheres''?

An atmosphere is sometimes used as a unit of pressure, meaning approximately 15 pounds per square inch. When a diver descends, the weight of the water above him exerts pressure on his body. At a depth of approximately 32 feet, the weight of the water will amount to 15 pounds per square inch, or one additional atmosphere. So three atmospheres means the diver is experiencing 45 pounds per square inch on his body at a depth of about 64 feet.

Would breathing cause you to lose or gain weight?

No, you won't gain or lose any weight at all. This is because as you inhale air, more mass enters your body (the mass of the air, which is now in your lungs), but your body expands a bit, thus taking up more space and increasing the buoyancy force of your body, the exact amount that the extra mass in your lungs increases gravity. this is because air is the fluid that we are in and so its own mass is negated by its own buoyancy, whether it is in our lungs or not. Now when we breathe air when in a fluid other then air we see that the weight does change. Like a scuba diver underwater. If they take a lung full of air under water (from an air tank) they become lighter, and when they exhale that air, they become heavier.

Why can height and weight be a problem in health?
