Rip tide

A riptide is a strong, offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide. It is a strong tidal flow of water within estuaries and other enclosed tidal areas. The riptides become the strongest where the flow is constricted. When there is a falling or ebbing tide, the outflow water is strongly flowing through an inlet toward the sea, especially once stabilized by jetties.[1] During these falling and ebbing tides, a riptide can carry a person far offshore. For example, the ebbing tide at Shinnecock Inlet in Southampton, New York, extends more than 300 metres (980 ft) offshore.[2] Because of this, riptides are typically more powerful than rip currents.

During slack tide, the water is motionless for a short period of time until the flooding or rising tide starts pushing the sea water landward through the inlet. Riptides also occur at constricted areas in bays and lagoons where there are no waves near an inlet.

These strong, reversing currents can also be termed ebb jets, flood jet, or tidal jets by coastal engineers because they carry large quantities of sand outward that form sandbars far out in the ocean or into the bay outside the inlet channel. The term "ebb jet" would be used for a tidal current leaving an enclosed tidal area, and "flood jet" for the equivalent tidal current entering it.

The term "rip tide" or "riptide" is often incorrectly applied to rip currents, which are not tidal flows. A rip current is a strong, narrow jet of water that moves away from the beach and into the ocean as a result of local wave action. They can flow quickly, are unpredictable and are a result of the shape of the coastline. Instead, a rip tide is caused by the Moon's gravitational pull and is a predictable rise and fall of the water level.[3]

The United States National Oceanic and Atmospheric Administration (NOAA) comments:

Rip currents are not rip tides. A specific type of current associated with tides may include both the ebb and flood tidal currents that are caused by egress and ingress of the tide through inlets and the mouths of estuaries, embayments, and harbors. These currents may cause drowning deaths, but these tidal currents or tidal jets are separate and distinct phenomena from rip currents. Recommended terms for these phenomena include ebb jet, flood jet, or tidal jet.[4]

Battle of Dan-no-ura

The battle of Dan-no-ura (壇ノ浦の戦い, Dan-no-ura no tatakai) was a major sea battle of the Genpei War, occurring at Dan-no-ura, in the Shimonoseki Strait off the southern tip of Honshū. On April 25, 1185, the fleet of the Minamoto clan (Genji), led by Minamoto no Yoshitsune, defeated the fleet of the Taira clan (Heike). The morning rip tide was an advantage to the Taira in the morning but turned to their disadvantage in the afternoon. The young Emperor Antoku was one of those who perished amongst the Taira nobles.The Taira were outnumbered, but some sources say that they had the advantage over the Minamoto in understanding the tides of that particular area, as well as naval combat tactics in general. The Taira split their fleet into three squadrons, while their enemy arrived en masse, their ships abreast, and archers ready. The beginning of the battle consisted mainly of a long-range archery exchange, before the Taira took the initiative, using the tides to help them try to surround the enemy ships. They engaged the Minamoto, and the archery from a distance eventually gave way to hand-to-hand combat with swords and daggers after the crews of the ships boarded each other. However, the tide changed, and the advantage was given back to the Minamoto.

One of the crucial factors that allowed the Minamoto to win the battle was that a Taira general, Taguchi Shigeyoshi, defected and attacked the Taira from the rear. He also revealed to the Minamoto which ship the six-year-old Emperor Antoku was on. Their archers turned their attention to the helmsmen and rowers of the Emperor's ship, as well as the rest of their enemy's fleet, sending their ships out of control. Many of the Taira saw the battle turn against them and committed suicide.Among those who perished this way were Antoku and his grandmother, Nun of the Second Rank, Taira no Tokiko the widow of Taira no Kiyomori.To this day, the Heike Crabs found in the Straits of Shimonoseki are considered by the Japanese to hold the spirits of the Taira warriors. The Taira attempted to toss the imperial regalia off the ship but only managed to get the sword and jewel into the water before the ship holding the regalia was captured.The jewel was recovered by divers; many presume the sword to have been lost at this time, though it is officially said to have been recovered and enshrined at Atsuta Shrine.

This decisive defeat of the Taira forces led to the end of the Taira bid for control of Japan. Minamoto no Yoritomo, the elder half-brother of Minamoto Yoshitsune, became the first shōgun, establishing his military government (bakufu) in Kamakura. In this battle the Taira lost Taira Tomomori, Taira Noritsune, Taira Norimori, Taira Tsunemori, Taira Sukemori, Taira Arimori and Taira Yukimori, who were killed.

Beirut (band)

Beirut is an American band which was originally the solo musical project of Santa Fe native Zach Condon. Beirut's music combines elements of indie-rock and world music. The band's first performance was in New York, in May 2006, to support its debut album, Gulag Orkestar.Condon named the band after Lebanon's capital, because of the city's history of conflict and as a place where cultures collide. Beirut performed in Lebanon for the first time in 2014, at the Byblos International Festival.

Cape d'Or

Cape d'Or is a headland located near Advocate, Cumberland County, on the Bay of Fundy coast of the Canadian province of Nova Scotia.

The cape marks the north point of the entrance to the Minas Basin. Cape d'Or is a continuation of the North Mountain tholeiitic basalt formation, and is marked by dramatic 200 m (660 ft) cliffs on its western side and 30 m (98 ft) cliffs on its southern side overlooking treacherous tidal currents in the Minas Channel. A basalt reef extends from the Cape into the Bay of Fundy where it intersects the violent waters of the Dory Rips, a rip tide created by the collision of three strong tidal currents.

Current (fluid)

A current in a fluid is the magnitude and direction of flow within that fluid. An air current presents the same properties specifically for a gaseous medium.

Types of fluid currents include

Boundary current

Current (stream), a current in a river or stream

Longshore current

Ocean current

Rip current

Rip tide

Subsurface currents

Turbidity current

Dark Life

Dark Life is the first book in a futuristic adventure fiction and science fiction series of the same name by Kat Falls. The novel was published May 1, 2010 by Scholastic. Falls has written a sequel: Rip Tide. Scholastic has published a study guide for the books.

Film rights to the story were acquired by Gotham Group in 2010. Publishing rights outside the USA were sold in six languages.

Dory Rips

The Dory Rips is a phenomenon involving extreme tidal agitation of waters located in the Bay of Fundy off the headland of Cape d'Or in Nova Scotia, Canada.

The phenomenon occurs at the entrance to the Minas Basin, which is known for the globe's highest tides.The turbulence does not result from a simple rip tide, but rather from the collision of three opposed tidal currents whose violence is enhanced by the presence of a subsurface reef that forces the water upward. The powerful incoming tidal current loops back and collides with itself while another current, coursing in semicircular fashion around Advocate Bay, slams into the collision point at a 90-degree angle.

East Harlem (song)

"East Harlem" is a song by indie folk band Beirut, from the band's third studio album The Rip Tide. The song was digitally released as a single on June 3, 2011 with "Goshen" as its B-side. The single was physically released on June 6, 2011 with limited copies and released on June 14, 2011 on Pompeii on blue, white, and red vinyl with a supply of 2,000 copies of each color.

Nantucket National Wildlife Refuge

Nantucket National Wildlife Refuge is a 24-acre (9.7 ha) range and was established in 1973 for its "particular value in carrying out the national migratory bird management program." The refuge, which is cooperatively managed with The Trustees of Reservations, encompasses 24 acres (9.7 ha) at Great Point. Nantucket National Wildlife Refuge is an un-staffed unit of the Eastern Massachusetts National Wildlife Refuge Complex. Nantucket National Wildlife Refuge consists of the Northeast tip of Nantucket, known as Great Point. The Refuge has been managed informally by TTOR several decades. TTOR owns the land immediately adjacent to Great Point, known as the Coskata-Coatue Wildlife Refuge. Great Point is known as one of the best surfcasting locations in New England because of the rip tide which brings bluefish and striped bass to the point. The Refuge is also a destination for hundreds of visitors each year seeking to enjoy a Nantucket beach or a tour of the Great Point Lighthouse. More information about the adjacent TTOR property is available on their website.

The refuge is an important stopover site for migratory birds and protects habitat for the federally listed piping plover and roseate tern, as well as the State-listed common and least tern. Gray and harbor seals are also frequently seen hauling out on the refuge. A variety of gull species also inhabit the refuge which at times can be detrimental to the successful nesting of shorebirds

Rip current

A rip current, often simply called a rip (or misleadingly rip tide), is a specific kind of water current which 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, and is strongest near 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 going on, and who may not have the necessary water skills, may panic, or exhaust themselves by trying to swim directly against the flow of water. Because of these factors, rips are the leading cause of rescues by lifeguards at beaches, and rips are the cause of an average of 46 deaths by drowning per year in the United States.

A rip current is not the same thing as undertow, although some people use the term incorrectly when they often mean a rip current. Contrary to popular belief, neither rip nor undertow can pull a person down and hold them under the water. A rip simply carries floating objects, including people, out beyond the zone of the breaking waves.

Riptide (disambiguation)

Rip tide is a strong tidal flow of water within estuaries and other enclosed tidal areas.

Riptide or rip tide may also refer to:

A common misnomer for a rip current, a fast narrow current running offshore and cutting through breaking waves

Willard Price

Willard DeMille Price (28 July 1887 – 14 October 1983) was a Canadian-born American traveller, journalist and author.

Price was born to a family of devout Methodists in Peterborough, Ontario. He spent his early childhood living on a farm before his family moved to Toronto and then Cleveland, Ohio in the United States when he was four. Price attended East High School and Western Reserve University where he funded his college degree by writing advertisements for local businesses and newspapers. During this time he gained notoriety as a young Methodist leader and developed a taste for adventure on long trips during vacations.

On graduating in 1909 Price confounded expectations by choosing not to enter a seminary, instead spending a year preaching as an unordained pastor. He then resolved to experience the "workaday world", a decision that took him to New York and then London. While there he developed a "painfully acute social awareness" while volunteering at a settlement house in Southwark. This inspired Price to become "a social worker with a pen".

Returning to New York in 1911 Price won a scholarship to the School of Philanthropy at Columbia University, where he acquired a MA and Litt.D. While there he wrote a number of campaigning newspaper and magazine articles including a first-hand account of the squalid conditions aboard a transatlantic liner, a survey of Newark's slums and an investigation of child labour conditions in a Pittsburgh iron and steel plant (with Herschel V. Jones). Price also worked as publicity secretary of the Methodist Board of Foreign Missions, completed his thesis on immigration and edited the journals Survey and World Outlook.

Price spent his later life as a "foreign correspondent and roving researcher" on behalf of newspapers, magazines, museums and societies (in particular the National Geographic Society and the American Museum of Natural History). He visited a total of 148 countries and circled the globe three times before his death.

Price documented these adventures in a series of adult non-fiction books, beginning with Rip Tide in the Southern Seas (1936). His early writing career focused in particular on Japan, where he lived from 1933 to 1938 and could see first-hand the country's militarization.

In 1999 Professor Laurie Barber of Waikato University (Hamilton, New Zealand) suggested that Willard Price may have spied for the United States. Indeed, Price admits to having done so in My Own Life of Adventure, one of two autobiographies he wrote in his later years. What remains unclear is whether Price was on the payroll of military intelligence.Price's travels also proved the inspiration for his highly popular Adventure series of novels for young readers, which describe the daring exploits of globe-trotting teenage zoologists Hal and Roger Hunt.

Shortly before his death, Price commented that:

My aim in writing the Adventure series for young people was to lead them to read by making reading exciting and full of adventure. At the same time I want to inspire an interest in wild animals and their behavior. Judging from the letters I have received from boys and girls around the world, I believe I have helped open to them the worlds of books and natural history.

In 2006, the Price family sold the copyrights and related legal rights for the fourteen Adventure series titles, plus the right to use Price's name, to London-based Fleming Literary Management for an undisclosed six-figure sum.
