USS Jeannette (1878)

USS Jeannette (1878) is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand USS Jeannette (1878) rather than just read about it. In short: USS Jeannette was a naval exploration vessel which, commanded by George W. De Long, undertook the Jeannette expedition of 1879–1881 to the Arctic.

Key takeaways

  • USS Jeannette (1878) belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect USS Jeannette (1878) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of USS Jeannette (1878) from memory before moving on to harder problems.

Reference excerpt

USS Jeannette was a naval exploration vessel which, commanded by George W. De Long, undertook the Jeannette expedition of 1879–1881 to the Arctic. After being trapped in the ice and drifting for almost two years, the ship and her crew of 33 were released from the ice, then trapped again, crushed and sunk some 300 nautical miles (560 km; 350 mi) north of the Siberian coast. The entire crew survived the sinking, but eight died while sailing towards land in a small cutter. The others reached Siberia, but 12 subsequently perished in the Lena Delta, including De Long. The vessel had begun her active career in 1861 as HMS Pandora, a Royal Navy gunboat. After more than a decade's service off the West African coast and in the Mediterranean, Pandora was retired from duty and sold as a private yacht to a British explorer, Allen Young. Young took her on two voyages to the Arctic, in 1875 and 1876, before selling her to James Gordon Bennett Jr., proprietor of the New York Herald, who changed her name to Jeannette. Although she sailed to the Arctic under the U.S. flag as USS Jeannette, subject to naval laws and discipline, Bennett remained responsible for the costs of the expedition.

Service history

Construction and launch The ship that became USS Jeannette began her life as a Royal Navy gunboat, built at the Pembroke Naval Dockyards in 1860. She was of wooden construction, 146 feet (45 m) in length and 25 feet (7.6 m) at the beam, with a draft of 13 feet (4.0 m). Her tonnage, calculated by Builder's Measure, was 428 tons, with a displacement of 570 tons. She was rigged as a barque, but her principal means of propulsion was by a steam-driven screw. After her launch on 7 February 1861, Pandora was taken from Pembroke to Portsmouth Dockyard, where she was fitted with her engines and boilers, and underwent trials before commissioning. On October 22, she concluded her trials successfully, achieving a speed of 9.25 knots over a measured mile.

Pandora In November 1861, during the American Civil War, the diplomatic incident known as the Trent affair caused the Admiralty to bring additional ships into active service. On 27 December 1861, Pandora was formally commissioned, as tender to HMS Majestic, and the following day sailed for Liverpool where Majestic was berthed. The crisis was quickly resolved; Pandora remained at Liverpool until January 1862 before returning to Portsmouth. In April 1863, Pandora left Portsmouth for service off the coast of West Africa. On 2 October 1866, she collided with sister ship HMS Griffon off Little Popo. Griffon sank; her crew were rescued. Pandora returned in Portsmouth in 1867, and was transferred to the reserve. In April 1868, she was recommissioned, and returned to West Africa. Two years later she was transferred to the Mediterranean squadron, based at Valletta, Malta. This was her last commission in British naval service. In July 1872, after two years in the Mediterranean, she returned to Spithead, where she was taken out of active commission and berthed in Portsmouth as part of the steam reserve.

Allen Young

In 1875, Pandora was acquired from the navy by the yachtsman Allen Young, for use in one of the last expeditions sent to the Canadian Arctic to investigate the disappearance, 30 years previously, of the Franklin expedition. Young sailed in June 1875, seeking not only for signs of Franklin, but to discover and complete the Northwest Passage, then unconquered. He was unsuccessful on both counts; he found no traces of Franklin, was stopped by ice in Peel Sound, and he returned to England. One of the financiers for this venture was James Gordon Bennett Jr., the owner of the New York Herald. In 1876, Young took Pandora north again, for a second attempt on the Northwest Passage. He was diverted by a request from the Admiralty to look for the British Arctic Expedition under George Nares, which was engaged in an attempt to reach the North Pole from Smith Sound. The expedition did not require Pandora's assistance, and Young returned home. In 1877, Young sold Pandora to Bennett, who was planning his own Arctic expedition.

Polar expedition

Bennett's plan was to sail a vessel through the Bering Strait, on the theory that the warm Pacific Ocean current known as the Kuro Siwo would provide a "thermometric gateway" whereby a suitable ship might reach the North Pole. This was the primary objective, but the ship was also equipped for scientific observation. By agreement with the U.S. Department of the Navy, Bennett would finance the expedition, but would sail under naval laws and discipline, and would be commanded by a naval officer, George W. De Long. Pandora was renamed Jeannette, after Bennett's sister, and in January 1879 arrived at the Mare Island Naval Shipyard, to be fitted for Arctic service.

Worked examples

Example 1 — a first encounter with USS Jeannette (1878)

Start with the simplest possible case. Write down what USS Jeannette (1878) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to USS Jeannette (1878) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about USS Jeannette (1878) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of USS Jeannette (1878)

In research
USS Jeannette (1878) appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses USS Jeannette (1878) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
USS Jeannette (1878) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1861 ships, Arctic exploration vessels, Exploration ships, so understanding it makes those chapters shorter.
In everyday life
Look for USS Jeannette (1878) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
