They enjoyed the freedom of skin diving in shallow waters along the coast.
Skin diving allows for a closer and more intimate exploration of marine life.
What is "skin diving"?

Skin diving is a form of underwater diving where a person uses minimal equipment, typically just a mask, snorkel, and fins, to explore the water. Unlike scuba diving, skin divers do not carry tanks of air and rely on holding their breath while diving. This activity is often done in shallow waters, such as near reefs or along coastlines, and is popular for activities like observing marine life or collecting shells. Skin diving requires good breath-holding ability and comfort in the water but is relatively simple compared to more advanced diving techniques.

洞穴潜水

the activity of underwater diving in water-filled caves using specialized equipment

What is "cave diving"?

Cave diving is a type of scuba diving where divers explore underwater caves. This activity requires specialized equipment, such as extra tanks, lights, and safety tools, because of the challenging environment and limited visibility in caves. Cave diving can be very dangerous due to tight spaces, dark conditions, and the need for careful planning to avoid getting lost or running out of air. Divers must be highly trained in both scuba diving and cave exploration techniques to safely navigate the often complex and narrow cave systems. It is typically done in remote areas where natural cave formations exist underwater.

技术潜水

the practice of diving beyond recreational limits using specialized equipment and techniques

What is "technical diving"?

Technical diving refers to advanced forms of scuba diving that go beyond the limits of recreational diving. It involves using specialized equipment, such as multiple tanks, mixed gases, and advanced diving tools, to explore deeper or more complex environments like wrecks, caves, or deep-sea areas. Technical divers often need to follow strict safety procedures due to the increased risks of deep dives, extended time underwater, and the use of different gases to avoid nitrogen narcosis or oxygen toxicity. This type of diving requires extensive training and knowledge of dive planning, navigation, and emergency protocols.

(随流潜水)

(随流潜水)

漂流潜水

a type of scuba diving where the diver is moved around by currents, allowing the water's flow to carry the diver along

What is "drift diving"?

Drift diving is a type of scuba diving where divers allow themselves to be carried along by the current while exploring underwater. Instead of swimming against the current, divers use the flow of water to move, making it easier to cover large areas with minimal effort. Drift diving is often done in locations with strong currents, like rivers, ocean reefs, or channels, and can offer the opportunity to see marine life and natural features without exerting much energy. However, it requires good buoyancy control and the ability to stay close to the dive group while being carried by the current.

夜间潜水

a type of scuba diving where the diver dives underwater at night using specialized lights

What is "night diving"?

Night diving is a type of scuba diving that takes place after dark. Divers use special lights to explore underwater, as natural light is no longer available. The underwater environment can appear very different at night, with many marine creatures becoming more active. Night divers must be extra careful, as visibility is limited and the ocean can feel more mysterious. This type of diving requires good planning, as divers need to be prepared for lower visibility, colder temperatures, and the potential for disorientation. Night diving offers a unique experience, allowing divers to see nocturnal marine life and experience the ocean in a completely different way.

沉船潜水

a type of scuba diving where the diver explores sunken ships and other underwater structures

What is "wreck diving"?

Wreck diving is a type of scuba diving where divers explore sunken ships, airplanes, or other structures. These wrecks, often located in oceans or lakes, offer an exciting opportunity to learn about history and marine life. Over time, many wrecks become artificial reefs, providing homes for various fish and other sea creatures. Wreck diving can be challenging because it often involves navigating through confined spaces, dealing with limited visibility, and managing the risks associated with deep or technical dives. It requires good dive training, preparation, and respect for the environment and the wrecks themselves, which are often considered historical sites.

(减压症)

(减压症)

减压病

a condition where sudden pressure changes cause nitrogen bubbles in the body, leading to symptoms like joint pain and fatigue

What is "decompression sickness"?

Decompression sickness, also known as "the bends," is a condition that occurs when a person experiences a quick decrease in pressure, typically after diving or going up to very high places too quickly. This sudden change in pressure can cause nitrogen bubbles to form in the bloodstream and tissues, leading to various symptoms such as joint pain, fatigue, dizziness, headache, or even more serious neurological or respiratory problems. Decompression sickness most commonly affects scuba divers, pilots, or individuals working in high-pressure environments. Treatment typically involves providing oxygen and gradually increasing pressure to safely remove nitrogen from the body. In serious cases, hyperbaric oxygen therapy may be necessary to ease symptoms and prevent further complications.

底潜时间

the duration a diver spends underwater during a single dive, typically measured from descent to ascent

What is "bottom time"?

Bottom time refers to the total amount of time a diver spends underwater from the beginning of descent until the start of ascent. It is an important factor in scuba diving because it affects how much nitrogen builds up in the body, which determines how long a diver can stay at certain depths safely. Divers use dive tables or computers to track bottom time and avoid staying too long, which can lead to decompression sickness. Properly managing bottom time helps ensure a safe and enjoyable dive while reducing the risk of health complications.

(潜水呼吸再生器)

潜水再呼吸器

a device that recycles air, extending dive time while conserving gas

What is a "diving rebreather"?

A diving rebreather is a piece of equipment used in scuba diving that recycles the air a diver exhales. Instead of releasing the exhaled air into the water like a regular regulator, the rebreather filters and removes carbon dioxide, then adds oxygen to create breathable air. This allows the diver to use less gas and stay underwater for longer periods without the need for frequent tank changes. Rebreathers are commonly used in deep dives, technical diving, and by divers exploring environments where extended bottom time is necessary. They are more complex than standard scuba systems and require specialized training to use safely.

a method of providing oxygen to divers underwater on demand to treat decompression sickness or other diving-related injuries

What is "demand valve oxygen therapy"?

Demand valve oxygen therapy is a technique used to administer oxygen to divers in emergency situations, especially for treating decompression sickness or other diving-related issues. The system uses a demand valve, which releases oxygen only when the diver inhales, ensuring efficient use of the oxygen. This helps restore normal oxygen levels in the body, reducing the effects of nitrogen buildup after a dive. The therapy is commonly used in controlled conditions, such as dive chambers or on-site during emergencies, to provide immediate relief and aid in the diver’s recovery.

What is a "mouthpiece"?

A mouthpiece is a small, simple device designed to be placed in the mouth to help with breathing or controlling airflow. It is commonly used in activities like scuba diving, snorkeling, and some medical treatments. In scuba diving, the mouthpiece is attached to the regulator, allowing the diver to breathe in air from the tank. It is made of soft, durable materials for comfort and to create a seal in the mouth, ensuring the diver can inhale and exhale without air escaping. The mouthpiece can also be found in other equipment, like breathing machines or sports gear.
