Rip Currents
A rip current, often simply called a rip (or misleadingly a '' rip tide''), is a specific kind of water current that can occur near beaches with breaking waves. A rip is a strong, localized, and narrow current of water which moves directly away from the shore, cutting through the lines of breaking waves like a river running out to sea. The current in a rip is strongest and fastest next to the surface of the water. Rip currents can be hazardous to people in the water. Swimmers who are caught in a rip current and who do not understand what is happening, or who may not have the necessary water skills, may panic, or they may exhaust themselves by trying to swim directly against the flow of water. Because of these factors, rip currents are the leading cause of rescues by lifeguards at beaches, and in the United States, they are the cause of an average of 46 deaths by drowning per year. A rip current is not the same thing as undertow, although some people use the term incorrectly wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rip Current Warning Signs At Mission Beach
Rest in peace (RIP), a phrase from the Latin (), is sometimes used in traditional Christian services and prayers, such as in the Catholic, Lutheran, Anglican, and Methodist denominations, to wish the soul of a decedent eternal rest and peace. It became ubiquitous on headstones in the 18th century, and is widely used today when mentioning someone's death. Description The phrase ''dormit in pace'' (English: " esleeps in peace") was found in the catacombs of the early Christians and indicated that "they died in the peace of the Church, that is, united in Christ." The abbreviation R.I.P., meaning ''Requiescat in pace'', "Rest in peace", continues to be engraved on the gravestones of Christians, especially in the Catholic, Lutheran, and Anglican denominations. In the Tridentine Requiem Mass of the Catholic Church the phrase appears several times. Other variations include "Requiescat in pace et in amore" for " ay he/sherest in peace and love", and "In pace requiescat et in a ...

Cross Sea
A cross sea (also referred to as a squared sea or square waves) is a sea state of wind-generated ocean waves that form nonparallel wave systems. Cross seas have a large amount of directional spreading. This may occur when water waves from one weather system continue despite a shift in wind Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few .... Waves generated by the new wind run at an angle to the old. Two weather systems that are far from each other may create a cross sea when the waves from the systems meet at a place far from either weather system. Until the older waves have dissipated, they can present a perilous sea hazard. This sea state is fairly common and a large percentage of ship accidents have been found to occur in this state. Vessels fare better against large waves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surf Lifesaving
Surf lifesaving is a multifaceted social movement that comprises key aspects of voluntary lifeguard services and competitive surf sport. Originating in early 20th century Australia, the movement has expanded globally to other countries, including New Zealand, Ireland, South Africa, and the United Kingdom. Surf lifesavers in Australia are colloquially known as "Clubbies". History Surf lifesaving originated in Australia in 1907 in response to drownings at local beaches in Sydney. Such groups became necessary following the relaxing of laws prohibiting daylight bathing on Australian beaches."Surf Life Saving - Stories from Australia's Culture and Recreation Portal" . nline Commonwealth ...

Underwater Diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep di ...

Treading Water
Treading water or water treading is what a Human swimming, swimmer can do while in a vertical position to keep their head above the surface of the water, while not providing sufficient directional thrust to overcome inertia and propel the swimmer in any specific direction. As it expends less energy than traditional strokes, it is often used by swimmers to rest in between periods of exertion without having to leave the water. In figurative language, the expression "treading water" has become a metaphor for an effort expected to create motion, but which actually results in merely staying in one, possibly barely sustainable, place. Methods Any sort of movement that allows the swimmer to do this can be classified as treading water, but it is more efficient to move the arms and legs in a specific fashion. Non-swimmers often splash and kick in an effort to stay above the surface but their lack of technique along with shortness of breath and the panic factor make for a very ineffective ...

Treadmill
A treadmill is a device generally used for walking, running, or climbing while staying in the same place. Treadmills were introduced before the development of powered machines to harness the power of animals or humans to do work, often a type of mill operated by a person or animal treading the steps of a treadwheel to grind grain. In later times, treadmills were used as punishment devices for people sentenced to hard labor in prisons. The terms ''treadmill'' and ''treadwheel'' were used interchangeably for the power and punishment mechanisms. More recently, treadmills have instead been used as exercise machines for running or walking in one place. Rather than the user powering a mill, the device provides a moving platform with a wide conveyor belt driven by an electric motor or a flywheel. The belt moves to the rear, requiring the user to walk or run at a speed matching the belt. The rate at which the belt moves is the rate of walking or running. Thus, the speed of running m ...

Drowning
Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance. After successful resuscitation, drowning victims may experience breathing problems, vomiting, confusion, or unconsciousness. Occasionally, victims may not begin experiencing these symptoms until several hours after they are rescued. An incident of drowning can also cause further complications for victims due to low body temperature, aspiration of vomit, or acute respiratory distress syndrome (respiratory failure from lung inflammation.). Drowning is more likely to happen when spending extended periods of time near large bodies of water. Risk factors for drowning include alcohol use, drug use, epilepsy, minimal swim training or a complete lack of training, and, in the case of children, a lack of supervision. Common drowning lo ...
