What do scuba divers use to tell how far down they are?
scuba divers use pressure meter because the deeper down you go the more pressure builds upAdditiona depth gauge or a dive computer
Is scuba diving a type of science?
The best answer is probably no. Safe scuba diving relies heavily on a knowledge of physics, gas laws and even physiology. Since it generally takes place in the ocean, it often involves marine biology. In that respect scuba is far more reliant on science than most other activities. Generally, though, scuba is a recreational activity for most divers and a vocation for others.
Where can someone get 'Odlaw Binoculars' for deep sea divers?
at the far left corner. go up a bit two girls will be scuba-diving off a rock in green and white and red and white clothes. there next to the right ones foot.
Can you scuba dive in the Atlantic ocean?
You can if you have a Boat and enough oxygen. Do not go to far down or when you try to come up you'll have no oxygen.
Is scuba for fun or money or both?
Its for both. You can do it for adventure or fun. But, while diving, you may find some hidden treasure also. EDIT! Dont touch hidden treasure!! Thats a BIG no no as far as a lot of divers are concerned. The items and life in the sea are there to stay! leave them for other divers to see as well. Unless you are on a specified archeological or Recovery program, DONT bring items from wrecks back!
How far can divers reach underwater without dying?
about 200 ft.
How deep can a technical diver dive?
Divers have dived over 1,000 feet on scuba (rarely - only four times so far), so that is probably the outer edges of the limit for technical divers.The deepest level you can be 'certified' to dive at is 330 feet/100 meters (TDI Advanced Trimix/IANTD Expedition Trimix). Wrecks like the HMHS Brittanic and the SS Transylvania are dived with some degree of regularity at depths around 450 feet.But there are no scuba police, and many technical divers in fact exceed those depths regularly. The deepest depths to which technical divers are known to dive with any level of regularity are around 550 or so feet (thinking of the Jolanda in the Red Sea at various depths down to and slightly below 550 feet).Dives below 600 feet are extraordinarily rare.
What are the scuba diver is 31 feet below the surface of the water she dives down an additional 15 feet how far would she have to rise to reach the surface of the water?
16 Feet
Are dinosaurs in your backyard?
Most likely. If you dig down far enough (very far down) you may find some fossils of some kind.
What is free diving?
free diving is where a group or one person goes into the sea and dives; without a oxygen tank. they then proceed to go as far down as they can and the one who goes the furthest down wins. free divers are required to have a good lung capacity and as healthy body, it is advised NOT to try this, free divers are proffesionals and have had many years of training. Many risks can be taken for example; too much pressure on your heart and body causing breakages, heart attacks and of course drowning. It is advised that you have a doctor or someone with a medical qualification to be present at events to ensure the safety of free divers.
Scuba gear how far can you go down?
Recreational divers are certified by the recreational training agencies (PADI, NAUI, SSI, BSAC, etc) to depths as deep as 130 feet. Most recreational diving takes place above 100 feet and many regional dive operator organizations, including the Cayman Islands Watersports Association, officially limit dives to 100 feet. In fact, most recreational dives occur in relatively shallow depths of 60 feet or less, since most coral and sea life exists above those depths. Scuba diving, however, is not limited to recreational diving. Self Contained Underwater Breathing Apparatus (SCUBA) allows technical and commercial diving to depths well in excess of 130 feet. Humans reach a physiological limit of about 210 feet using normal air as a breathing gas. Below this depth, the oxygen in air reaches partial pressures that become toxic. For this reason, deeper dives are accomplished using mixed breathing gases that contain reduced perentages of oxygen. Deeper depths also increase the risk of decompression illness (also called the "bends"), caused by intert gases (primarily nitrogen) being absorbed by body tissues during prolonged exposure at elevated pressures. Ascending divers require "decompression stops" during ascent to allow time for these absorbed gases to escape from body tissues. It is to avoid these mandatory decompression stops that recreational divers are limited to 130 feet. With the right training, equipment and breathing gas, scuba dives have been made to great depths. The current record for an open circuit scuba dive is 318M (1042 feet). This dive required over 8 hours of decompression stops during the ascent. [All depths in feet, above, refer to feet of sea water (FSW).]
Is oceanography mainly scuba-diving?
Oceanography is like geography in the sea. You study the geography of the seabed and the nature of the water, such as salinity, turbidity currents etc. Although oceanographers may like scuba diving it is unlikely that is will be part of their job because using SCUBA you can only visit a tiny amount of the oceans. Lots of oceanographers are involved in oil exploration for example where the water would be far to deep to reach with scuba.
