Question: In what ocean did the USS Cyclops disappear?

full_context: Document 1: SS Edmund Fitzgerald: SS "Edmund Fitzgerald" was an American Great Lakes freighter that sank in a Lake Superior storm on November 10, 1975, with the loss of the entire crew of 29. When launched on June 7, 1958, she was the largest ship on North America's Great Lakes, and she remains the largest to have sunk there.
Document 2: Cyclops (novel): Cyclops is an action-adventure novel by Clive Cussler. This is the 8th book featuring the author’s primary protagonist, Dirk Pitt. A wealthy American financier disappears on a treasure hunt in an antique blimp. From Cuban waters, the blimp drifts toward Florida with a crew of dead men—Soviet cosmonauts. Dirk Pitt discovers a shocking scheme: a covert group of U.S. industrialists has put a colony on the moon, a secret base they will defend at any cost. Threatened in space, the Russians are about to strike a savage blow in Cuba—and only Dirk Pitt can stop them. From a Cuban torture chamber to the cold ocean depths, Pitt is racing to defuse an international conspiracy that threatens to shatter the Earth!
Document 3: Superior Shoal: The Superior Shoal is a geologic shoal of approximately 20 sqmi located 50 mi north of Copper Harbor, Michigan in the middle of Lake Superior whose highest point lies only 21 ft below the lake's surface. The shoal is a hump of Keweenawan basaltic lava flows with ophitic interiors and amygdaloidal tops in an otherwise deep part of the lake, and though fishermen had known of its existence for generations it was only officially charted in 1929. It has been theorized that the World War I French minesweepers "Inkerman" and "Cerisoles", which disappeared during their maiden voyage on Lake Superior in mid-November 1918, may have run aground on this shoal and some have theorized that it may have been to blame for both the disappearance of the "Flying Dutchman of the Great Lakes" on November 21, 1902 and the sinking of the "Titanic of the Great Lakes" on November 10, 1975 (the "SS Bannockburn" and SS "Edmund Fitzgerald", respectively). It is one of the known off-shore spawning and foraging habitats for the juvenile lean lake trout.
Document 4: Vincent Gaddis: Vincent Hayes Gaddis (December 28, 1913 – February 26, 1997) was an American author who invented the phrase "Bermuda Triangle", which he used first in the cover article for the 1964 February issue of the magazine "Argosy". He popularized many stories about anomalous and paranormal phenomena in a style similar to that of Charles Fort.
Document 5: Super-Sargasso Sea: The Super-Sargasso Sea is the dimension into which lost things go, whose existence was proposed by Charles Fort, writer and researcher into anomalous phenomena. It may be thought of as the spontaneous, anomalous teleportation of an object into another dimension. Fort did not actually believe that it existed but, in the vein of the ancient Greek skeptics, he wished only to present a theory that was just as plausible as those in the mainstream. The name alludes to the Sargasso Sea of the Atlantic Ocean, which lies next to the Bermuda Triangle.
Document 6: Milt Machlin: Milt Machlin (June 26, 1924 – April 3, 2004) was an American journalist, author and adventurer. He is best known for coining the phrases "Bermuda Triangle" and "Abominable Snowman," as well as his expedition to find scion Michael Rockefeller, who disappeared in New Guinea in 1961.
Document 7: Martin Bayerle: Captain Martin Gerard Bayerle (born April 23, 1951) is an American treasure hunter and author, best known for finding the 1909 shipwreck of the White Star Liner RMS Republic. He is also star of the History Channel show "Billion Dollar Wreck." The "Republic" was the largest ship to sink in history to her day, only to be eclipsed by the loss of RMS Titanic in 1912. Capt. Bayerle and his company, Martha's Vineyard Scuba Headquarters, Inc. ("MAVIS") were referred to as "modern day pirates" by Judge Nancy Gertner of the United States District Court, District of Massachusetts in a 2005 opinion granting exclusive salvage rights to the "Republic" to MAVIS. MAVIS subsequently acquired legal title to the RMS Republic shipwreck and her contents in August 2011, with the U.S. District Court of Boston also barring all future claims.
Document 8: RMS Titanic: RMS "Titanic" ( ) was a British passenger liner that sank in the North Atlantic Ocean in the early morning hours of 15 April 1912, after it collided with an iceberg during its maiden voyage from Southampton to New York City. There were an estimated 2,224 passengers and crew aboard the ship, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history. The RMS "Titanic" was the largest ship afloat at the time it entered service and was the second of three "Olympic"-class ocean liner s operated by the White Star Line. The Titanic was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, her architect, died in the disaster.
Document 9: The Triangle (miniseries): The Triangle is a three-part US-British-German science fiction miniseries concerning the Bermuda Triangle, which first aired on Sci-Fi Channel in the US December 5–7, 2005. It was written by Dean Devlin, Bryan Singer and Rockne S. O'Bannon, directed by Craig R. Baxley, and produced by special effects experts Volker Engel and Marc Weigert, together with Kelly Van Horn, for Devlin's and Singer's production companies Electric Entertainment and Bad Hat Harry Productions, the BBC, and Engel's and Weigert's production company Uncharted Territory.
Document 10: RMS Republic (1903): RMS Republic was a steam-powered ocean liner built in 1903 by Harland and Wolff in Belfast, and lost at sea in a collision six years later while sailing for the White Star Line. A CQD distress call was issued on the new Marconi radio device, the first recorded, resulting in the saving of around 1500 lives. Known as the "Millionaires' Ship" on account of the number of well-known and immensely rich Americans who traveled by her, she was described as a "palatial liner" and was the flagship of White Star Line's Boston service.
Document 11: USS Cyclops (AC-4): USS "Cyclops" (AC-4) was one of four "Proteus"-class colliers built for the United States Navy several years before World War I. Named for the Cyclops, a primordial race of giants from Greek mythology, she was the second U.S. Naval vessel to bear the name. The loss of the ship and 306 crew and passengers without a trace within the area known as the Bermuda Triangle some time after 4 March 1918 remains the single largest loss of life in U.S. Naval history not directly involving combat. As it was wartime, there was speculation she was captured or sunk by a German raider or submarine, because she was carrying 10800 LT of manganese ore used to produce munitions, but German authorities at the time, and subsequently, denied any knowledge of the vessel. The Naval History & Heritage Command has stated she "probably sank in an unexpected storm" But the ultimate cause of the ship's fate is unknown.
Document 12: Red Triangle (Pacific Ocean): The Red Triangle is the colloquial name of a roughly triangle-shaped region off the coast of northern California, extending from Bodega Bay, north of San Francisco, out slightly beyond the Farallon Islands, and down to the Big Sur region, south of Monterey. The area has a very large population of marine mammals, such as elephant seals, harbor seals, sea otters, sea lions, and humans, which are favored prey of great white sharks. Around thirty-eight percent of recorded great white shark attacks on humans in the United States have occurred within the Red Triangle — eleven percent of the worldwide total. The area encompasses the beaches of the heavily populated San Francisco Bay Area, and many people enjoy surfing, windsurfing, swimming and diving in these waters.
Document 13: Bermuda Triangle: The Bermuda Triangle, also known as the Devil's Triangle, is a loosely-defined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances. Most reputable sources dismiss the idea that there is any mystery. The vicinity of the Bermuda Triangle is one of the most heavily traveled shipping lanes in the world, with ships frequently crossing through it for ports in the Americas, Europe, and the Caribbean islands. Cruise ships and pleasure craft regularly sail through the region, and commercial and private aircraft routinely fly over it.
Document 14: Doldrums: The doldrums is a colloquial expression derived from historical maritime usage, which refers to those parts of the Atlantic Ocean and the Pacific Ocean affected by the Intertropical Convergence Zone, a low-pressure area around the equator where the prevailing winds are calm. The doldrums are also noted for calm periods when the winds disappear altogether, trapping sailing ships for periods of days or weeks. The term appears to have arisen in the 18th century, when trans-equator sailing voyages became more common. Since this zone is where two trade winds meet, it is also called the Intertropical Convergence Zone. They roughly lie between latitudes 5° north and south.
Document 15: Sinking of the RMS Lusitania: The sinking of the Cunard ocean liner RMS "Lusitania" occurred on Friday, 7 May 1915 during the World War 1, as Germany waged submarine warfare against the United Kingdom which had implemented a naval blockade of Germany. The ship was identified and torpedoed by the German U-boat "U-20" and sank in 18 minutes. The vessel went down 11 mi off the Old Head of Kinsale, Ireland, killing 1,198 and leaving 761 survivors. The sinking turned public opinion in many countries against Germany, contributed to the American entry into World War I and became an iconic symbol in military recruiting campaigns of why the war was being fought.
