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).

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.

Sea (EP)

Sea EP is the second EP from Doves. It was self-released on the band's Casino Records label on 24 May 1999 on limited CD and 10" vinyl. The band dedicated the EP to Rob Gretton, who helped fund Doves' early releases as well as when the band played as Sub Sub. Rob died of a heart attack only a few days before the EP was released. In the music video for "Sea Song," the opening title card reads "For Rob."

Track listing

All songs written and composed by Jez Williams, Jimi Goodwin, and Andy Williams. 

Notes

Angler

Angler may refer to:

Angler (video game)

Angler is a British fishing video game that was published in 1983 by Virgin Games for the ZX Spectrum home computer.

Plot

Taken from the game's instructions:

" You are a fisherman out on the sea in your trusty trawler. Beneath you the sea is teeming with different layers of fish. By using your skill and judgement can you position your boat and drop your line to make the catch of a life-time?"

Gameplay

The player controls a boat along the top of the screen and has 100 casts to catch as many fish as possible.

Trivia

The cassette inlay contained a membership form to join the Virgin games club and a profile of the games writer, Dirk Olivier, born in 1945 in Porthcawl.

Angling

Angling is a method of fishing by means of an "angle" (fish hook). The hook is usually attached to a fishing line and the line is often attached to a fishing rod. Fishing rods are usually fitted with a fishing reel that functions as a mechanism for storing, retrieving and paying out the line. The hook itself can be dressed with lures or bait. A bite indicator such as a float, and a weight or sinker are sometimes used.

Angling is the principal method of sport fishing, but commercial fisheries also use angling methods such as longlining or trolling. Catch and release fishing is increasingly practiced by recreational fishermen. In many parts of the world, size limits apply to certain species, meaning fish below and/or above a certain size must, by law, be released.

Introduction

The species of fish pursued by anglers vary with geography. Among the many species of salt water fish that are caught for sport are swordfish, marlin, tuna, while in Europe cod and bass are popular targets. In North America the most popular fresh water sport species include bass, pike, walleye, muskellunge, yellow perch, trout, salmon, crappie, bluegill and sunfish. In Europe a large number of anglers fish for species such as carp, pike, tench, rudd, roach, European perch, catfish and barbel. South Africa has a great fishing coast where anglers fish for species like cod, White Steenbras, and Mussel Cracker, although many anglers never know what they'll catch. Some fish are sought for their value as food, others are pursued for their fighting abilities or for the difficulty of pursuit.
