What Are Buoys Used For

Floating structure or device

A buoy ()^[i] ^[2] is a floating device that tin can have many purposes. It tin be anchored (stationary) or immune to drift with ocean currents.

Types [edit]

Navigational buoys [edit]

Race course marker buoys are used for buoy racing, the near prevalent course of yacht racing and power boat racing. They delimit the course and must be passed to a specified side. They are too used in underwater orienteering competitions.
Emergency wreck buoys provide a clear and unambiguous means of temporarily mark new wrecks, typically for the kickoff 24–72 hours. They are coloured in an equal number of bluish and xanthous vertical stripes and fitted with an alternating bluish and yellow flashing light. They were implemented following collisions in the Dover Strait in 2002 when vessels struck the new wreck of the MVTricolor.^[iii]
Ice marking buoys mark holes in frozen lakes and rivers and so snowmobiles do not drive over the holes.
Big Navigational Buoys (LNB, or Lanby buoys) are automatic buoys over 10 m high equipped with a powerful light monitored electronically every bit a replacement for a lightvessel.^[4] They may be marked on charts every bit a "Superbuoy."^[five]
Lateral marker buoys
Safe water mark or fairway buoys mark the entrance to a channel or nearby landfall
Sea marks aid pilotage by marking a maritime channel, hazard or administrative expanse to let boats and ships to navigate safely. Some are fitted with wave-activated bells or gongs.
Wreck buoys mark a wrecked ship to warn other ships to keep abroad because of unseen hazards.
Light buoys provide demarcation at night.

Marker buoys [edit]

Buoys are often used to temporarily or permanently mark the positions of underwater objects:

Lobster trap buoys are brightly colored buoys making lobster trap locations so lobster fishers tin detect their lobster traps. Each fisher has a unique colour marker or registration number. They are allowed to haul only their own traps, and must display their buoy color or license number on their boat so law enforcement officials know what they should be hauling. The buoys are brightly coloured with highly visible numbers then they can be seen in poor visibility conditions similar rain, fog and ocean fume.^[6] ^[7]

Diving [edit]

Several types of marker buoys may be used by defined:

Decompression buoys are deployed by submerged SCUBA divers to mark their position underwater whilst doing decompression stops
Shot buoys marker dive sites for the boat safety encompass of scuba divers and so they can descend to dive sites more hands in conditions of depression visibility or tidal currents and more safely do decompression stops on their ascents.
Surface marking buoys are taken on dives by scuba divers to mark their positions underwater.^[eight]
Dive site demarcation buoys signal that defined are working in the marked surface area, to warn passing vessels to stay clear.

Rescue [edit]

Lifebuoys are lifesaving buoys thrown to people in the h2o to provide buoyancy. They ordinarily have a connected line assuasive them to be pulled in.
Cocky-locating datum mark buoys (SLDMB) are seventy% scale Coastal Ocean Dynamics Experiment (CODE)/Davis-style oceanographic surface drifters with drogue vanes between 30 and 100 cm deep,^[9] designed for deployment from U.S. Coast Guard vessels or airframes for search and rescue. They have very little surface surface area above water to minimize the effects on them off winds and waves.^[10]
Submarine rescue buoys are released in emergencies and for advice purposes.

Research [edit]

Profiling buoys are specialized buoys that adjust their buoyancy to sink at a controlled rate to 2,000 metres while measuring sea temperature and salinity. After a certain period, typically 10 days, they render to the surface, transmit their data via satellite, then sink again.^[11] Come across Argo (oceanography).
Tsunami buoys are anchored buoys that can detect sudden changes in undersea water pressure, and are a component of seismic sea wave warning systems in the Pacific Tsunami Alarm Center and Indian Oceans.
Wave buoys mensurate the motility of the h2o surface every bit a wave railroad train. The data they transmit is analysed to form statistics like meaning wave height and menses, and wave direction.
Conditions buoys measure atmospheric condition parameters such every bit air temperature, barometric pressure, and wind speed and management. They transmit this data, via satellite radio links such as the purpose-built Argos System or commercial satellite phone networks, to meteorological centres for forecasting and climate study. They may be anchored (moored buoys), or immune to migrate (drifting buoys) in the open up currents. Their position is calculated by the satellite. They are also referred to as ODAS buoys or Ocean Data Acquisition Systems^[12] and may exist marked on charts every bit "Superbuoys."^[5]

Mooring [edit]

Mooring buoys keep one end of a mooring cablevision or chain on the water's surface so ships and boats can tie to them. Many marinas mark them with numbers and assign them to detail vessels, or rent them to transient vessels.
Tripping buoys are used to continue one cease of a 'tripping line' on the water'south surface so that a stuck ballast can more easily be freed.

Military [edit]

Mark buoys, used in naval warfare (particularly anti-submarine warfare) emit light and/or fume using pyrotechnic devices to create the flare and fume. Ordinarily iii inches (76 mm) in bore and about 20 inches (500 mm) long, they are activated by contact with seawater and float on the surface. Some extinguish themselves after a specific period, while others are sunk when they are no longer needed.
Sonobuoys are used by anti-submarine warfare aircraft to detect submarines past SONAR
Target buoys simulate targets, such as small boats, in live-fire exercises by naval and coastal forces. They are normally targeted past medium-sized weapons such as heavy automobile guns, rapid fire cannons (~xx mm), autocannons (up to 40–57mm) and anti-tank rockets.

Specific forms [edit]

DAN buoys are used as:
- Large maritime navigational aids providing a platform for light and radio beacons
- Lifebuoys with flags, used on yachts and smaller pleasure craft
- Temporary markers in Danish seine fishing to mark net anchor positions
- Temporary markers ready by danlayers during minesweeping operations to bespeak the boundaries of swept paths, swept areas, known hazards, and other locations or reference points
- Temporary markers for rescue operations
Spar buoys are tall, thin buoys that float upright, eastward.g. R/P FLIP

Other [edit]

Infinite buoys, a common element in science fiction, are stationary objects in outer space that provide navigation data or warnings.^{[ citation needed ]}
"Mail buoys" are imaginary buoys used as a prank in the US Navy; a new sailor may exist given the task of locating one to retrieve not-existent mail.^[thirteen]

Other uses [edit]

The word "buoyed" can also be used figuratively. For example, a person can buoy up ('lift up') someone'due south spirits past providing aid and empathy.^[14]
Buoys are used in some wave power systems to generate electrical ability.^[15]
George A. Stephen, founder of Weber-Stephen Products Co., invented the kettle grill by cutting a metal buoy in half and fashioning a dome shaped grill to it with a rounded lid.^[16]
