Sea

A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic waters—considered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been travelled and explored since prehistory, the modern scientific study of the sea—oceanography—dates broadly to the British Challenger expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sections—including the IHO's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as seas.

Owing to the present state of continental drift, the Northern Hemisphere is now fairly equally divided between land and sea (a ratio of about 2:3) but the South is overwhelmingly oceanic (1:4.7).Salinity in the open ocean is generally in a narrow band around 3.5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers, or at great depths. About 85% of the solids in the open sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature. Surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses and by the rotation of the Earth (the Coriolis effect).

The Sea (band)

The Sea are a rock pop band formed in Cornwall, England in 2007. The band comprises brothers Peter Vine-Chisholm (lead vocals, guitar, keyboard) and Alex Chisholm (Drums, percussion and backing vocals). They are signed to Lusty Records in the UK and Popup Records in Europe.

History

Love Love Love and Get It Back

By April 2008, the duo won the XFM unsigned competition to play at Brixton Academy to 5000 people and went on to support The Enemy at London’s Brixton Academy. By October that year they completed their first extensive tour of the UK AND were invited to play the CMJ Music Marathon in New York.

The Sea’s debut single Love Love Love on their own label Lusty Records sold out within two months of release in January 2009, receiving critical acclaim in the UK music press from NME,Kerrang!,The Fly and was one of Pete Cashmore's singles of the week in The Guardian.

In April 2009 their debut album Get It Back was released in UK on Lusty Records and on Pop Up Records in Europe.

Sea (astronomy)

The Sea or the Water is an area of the sky in which many water-related, and few land-related, constellations occur. This may be because the Sun passed through this part of the sky during the rainy season.

Most of these constellations are named by Ptolemy:

Sometimes included are the ship Argo and Crater the Water Cup.

Some water-themed constellations are newer, so are not in this region. They include Hydrus, the lesser water snake; Volans, the flying fish; and Dorado, the swordfish.

Seah (unit)

The se'ah or seah (Hebrew: סאה‎) is a unit of dry measure of ancient origin used in Halakha (Jewish law), which equals one third of an ephah, or bath. Its size in modern units varies widely according to the criteria used for defining it.

According to Herbert G. May, chief editor of two classic Bible-related reference books, the bath may be archaeologically determined to have been about 5.75 gallons (22 liters) from a study of jar remains marked 'bath' and 'royal bath' from Tell Beit Mirsim. Since the bath unit has been established to be 22 litres, 1 se'ah would equal 7.33 litres or 7.33dm³.

In the context of a mikveh, a se'ah can be about twice as much in order to accommodate even the most stringent rabbinical ruling on immersion. A mikveh must, according to the classical regulations, contain enough water to cover the entire body of an average-sized person; based on a mikveh with the dimensions of 3 cubits deep, 1 cubit wide, and 1 cubit long, the necessary volume of water was estimated as being 40 se'ah of water. The exact volume referred to by a seah is debated, and classical rabbinical literature specifies only that it is enough to fit 144 eggs; most Orthodox Jews use the stringent ruling of the Avrohom Yeshaya Karelitz, according to which one seah is 14.3 litres, and therefore a mikveh must contain approximately 575 litres . This volume of water could be topped up with water from any source, but if there were less than 40 seahs of water in the mikveh, then the addition of 3 or more pints of water from an unnatural source would render the mikveh unfit for use, regardless of whether water from a natural source was then added to make up 40 seahs from a natural source; a mikveh rendered unfit for use in this way would need to be completely drained away and refilled from scratch.

90.9 Sea FM

90.9 Sea FM (callsign 4SEA) is a radio station on the Gold Coast, Queensland, Australia. It is part of the Southern Cross Austereo Today Network, and is also the network hub for the regional Today Stream, broadcasting shows at times from 9am - 12am across the Sea, Star and Hot FM Networks across Australia.

The Sea FM brand name and original logo was created by Gold Coast Broadcasters Pty Ltd for just the one station - 90.9 Sea FM - after the Gold Coast was granted a new commercial FM licence. 90.9 Sea FM began broadcasting in 1989 with programming consulted by Austereo. The original Sea FM on-air line-up was a strong team of experienced Announcers, many having made their name previously in Metropolitan radio including - Craig Bruce (FOX FM) & Sammy Power, Ian 'Lofty' Fulton (4IP), Grahame "Durry" Rodgers (2SM & 2NX), Sue Moses (2MMM & Channel 10), Gregg Easton (2UW & 4BK), Joe Miller (3XY & EON FM), Dean Miller and Simon Franks.

In November 2011, controversy erupted after rumours surfaced that popular long-term breakfast co-host, Moyra Major, was to be replaced by entertainer Charli Robinson, after Robinson had filled in for six weeks while Major was on maternity leave. It was reported that Major had been replaced due to a significant increase in ratings for the breakfast show during Robinson's stint as co-host.
