Sargasso Sea

For other uses, see Sargasso Sea (disambiguation).

The Sargasso Sea in the North Atlantic is bounded by the Gulf Stream on the west, the North Atlantic Current on the north, the Canary Current on the east, and the North Equatorial Current on the south.

The Sargasso Sea is a region in the gyre in the middle of the North Atlantic Ocean. It is bounded on the west by the Gulf Stream; on the north, by the North Atlantic Current; on the east, by the Canary Current; and on the south, by the North Atlantic Equatorial Current. This system of ocean currents forms the North Atlantic Gyre. All the currents deposit the marine plants and garbage they carry into this sea.

The Sargasso Sea is 700 statute miles wide and 2,000 statute miles long (1,100 km wide and 3,200 km long). It stretches from roughly 70 degrees west to 40 degrees west, and from 20 degrees north to 35 degrees north. Bermuda is near the western fringes of the sea. The Sargasso Sea is the only "sea" without shores. The ocean water in the Sargasso Sea is distinctive for its deep blue color and exceptional clarity, with underwater visibility of up to 200 feet (61 m).

History

Portuguese sailors were among the first to discover this region in the 15th century, naming it after the Sargassum seaweed growing there (sargaço / sargasso in Portuguese). However, the sea may have been known to earlier mariners, as a poem by the late 4th century AD author, Rufus Festus Avienus, describes a portion of the Atlantic as being covered with seaweed, citing a now-lost account by the 5th-century BC Carthaginian explorer Himilco the Navigator. Christopher Columbus and his men also noted the Saragasso Sea, and brought reports of the masses of seaweed on the surface.

Ecology

The Sargasso Sea is home to seaweed of the genus Sargassum, which floats en masse on the surface there. The sargassum is not a threat to shipping, and historic incidents of sailing ships being trapped there are due to the often calm winds of the horse latitudes.

The Sargasso Sea also plays a major role in the migration of the European eel and the American eel. The larvae of both species hatch there and go to Europe or the East Coast of North America. Later in life, they try to return to the Sargasso Sea to lay eggs. It is also believed that after hatching, young Loggerhead Sea Turtles use currents, such as the Gulf Stream to travel to the Sargasso Sea, where they use the Sargassum as cover from predation until they are mature.

The Sargasso Sea was the subject of a recent metagenomics effort called the Global Ocean Sampling (GOS) survey by J. Craig Venter and others, to evaluate the diversity of microbial life there. The results have indicated that, contrary to previous theories, the area has a wide variety of prokaryotic life.^{[citation needed]}

Owing to surface currents, the Sargasso accumulates a high concentration of non-biodegradable plastic waste. The huge North Atlantic Garbage Patch in the area is similar to another ocean phenomenon, the Great Pacific Garbage Patch.

Depictions in popular culture

Lines of sargassum in the Sargasso Sea

The Sargasso Sea is often portrayed in literature and the media as an area of mystery.

The Sargasso Sea features in classic fantasy stories by William Hope Hodgson, such as his novel The Boats of the "Glen Carrig" (1907), Victor Appleton's Don Sturdy novel, Don Sturdy in the Port of Lost Ships: Or, Adrift in the Sargasso Sea, and several related short stories. Jules Verne's Twenty Thousand Leagues Under the Sea describes the Sargasso Sea and gives an account of its formation.

Edwin Corley's novel, Sargasso, revolves around a fictional account of Apollo 19 splashing down in the Sargasso sea empty. In Marvel 1602, it is where the Fantastick Four gained their powers. Jean Rhys's novel Wide Sargasso Sea plays with the idea that a woman can become lost in her own society and thus driven out of her mind, à la Charlotte Brontë's mad woman in the attic. Fred Andrew's mystery novel Plato's Pond features the fictitious land of Gaia, which is a continent in the middle of the Sargassum Sea.

The Sargasso Sea was the venue for the Doc Savage adventure "The Sargasso Ogre" written by Lester Dent under the pseudonym Kenneth Robeson and published in the October 1933 issue of the Doc Savage pulp magazine.

The 1923 silent film The Isle of Lost Ships an atmospheric adventure from director Maurice Tourneur takes place in the Sargasso Sea. The film was based on Crittenden Marriott's 1909 novel The Isle of Dead Ships. The Isle of Lost Ships is now a lost film.

The 1960-62 live action/marionette children's syndicated television show, Diver Dan contained at least two episodes set in the Sargasso Sea, Ep. 21 Sargasso Sea [1] and Ep. 22 Lost in the Sargasso Sea [2]. For many children of the baby boomer generation, that was their first introduction to the existence and novelty of the Sargasso Sea.

The 1968 movie The Lost Continent was set in a highly fictionalized Sargasso Sea where Spanish galleons, trapped for centuries in seaweed, are found in modern times, along with a society of descendants of Conquistadores and sea monsters.

The 1912 poem "Portrait D'une Femme" by Ezra Pound alludes to the Sargasso Sea in the line "Your mind and you are our Sargasso Sea, London has swept about you this score years".

In the 1978 Anime television series, Space Pirate Captain Harlock, Captain Harlock went to the Sargasso Sea where crew would encounter false lost ships.

The 2007 music video for the song Dashboard by indie group Modest Mouse features a sea captain telling the story of how he lost his hand to a giant fish while sailing in Sargasso Sea.
