Carnegie was a brigantine-rigged sailing yacht, equipped as a scientific research vessel, constructed almost entirely from wood and other non-magnetic materials to allow sensitive magnetic measurements to be taken for the Carnegie Institution for Science's Department of Terrestrial Magnetism at their headquarters in Washington, D.C.. She carried out a series of cruises from her launch in 1909 to her unfortunate destruction by an onboard explosion and fire while in port in 1929. She covered almost 300,000 miles (500,000 km) in her twenty years at sea in the cause of scientific knowledge. [1]
The Carnegie Rupes on the planet Mercury are named after this research vessel. [2]
Louis Agricola Bauer, the first director of the Department of Terrestrial Magnetism at the Carnegie Institution, wanted to focus on acquiring oceanic magnetic data to improve the understanding of the Earth's magnetic field. [3] After an experiment in which the brigantine Galilee was adapted by removing as much magnetic material as possible, it became clear that a new entirely non-magnetic ship was needed. After convincing the institution's board, Bauer set about getting such a vessel built. Carnegie was designed by naval architect Henry J. Gielow and built at the Tebo Yacht Basin Company yard in Brooklyn, New York. Gielow's design minimised the amount of magnetic materials used in its construction and fittings. Locust trunnels were used to hold together the timbers with the help of some bronze or copper bolts. [1] Carnegie was primarily a sailing vessel, but its unique, non-ferrous, auxiliary engine was capable of propelling the vessel in calm weather at a speed of 6 knots. [4] The construction used white oak, yellow pine, and Oregon pine with copper or bronze-composition metal for all the fastenings in the hull or rigging. [5] The anchors were made of bronze and were attached to 11 inches (28 cm) hemp cables. A reserve engine was required to increase manoeuvrability and allow passage through the doldrums, so Carnegie was fitted with a producer gas engine, made mainly of copper and bronze, using coal as a fuel. She cost $115,000 (about 10 million dollars today) to build. [3]
Carnegie was 155.5 feet (47.4 m) long with a beam of 33 feet (10 m). She was rigged as a brigantine, with square sails on the foremast, giving a total sail area of 12,900 square feet (1,200 m2). [1] The most distinctive feature was the observation deck, with its two observing domes made of glass in bronze frames. This allowed observations to be made under all weather conditions. [3]
Between 1909 and 1921 Carnegie carried out 6 cruises, including one where she managed the fastest circumnavigation of the south polar continent of Antarctica by a sailing vessel, in 118 days, [3] a testing voyage where thirty icebergs were sighted on a single day. [6] William John Peters captained cruises I and II, James P. Ault captained cruises III, IV, and VI, and Harry Marcus Weston Edmonds captained cruise V. During the 6 cruises the Carnegie sailed more than 250,000 nautical miles and traversed all oceans between latitudes 80º North and 60º South. [7] From 1921 to 1927 Carnegie was laid up for an extensive refit / refurbishment, including new deck timbers and a thicker copper hull. The old producer gas engine was replaced with a gasoline fuelled one. In 1928, under Captain James P. Ault, Carnegie set off on her seventh cruise, which was intended to take three years. [1] Soundings taken during this voyage discovered and named the Carnegie Ridge off-shore of Ecuador and the West Coast / Pacific Ocean of South America. [6]
After completing 43,000 miles (69,000 km) of the planned voyage, Carnegie put into the port of Apia, Samoa for supplies on 28 November 1929. While refuelling with gasoline there was an explosion, which mortally wounded Captain Ault and killed the cabin boy. Carnegie burnt to the waterline within a few hours. [1]
Carnegie carried a wide range of oceanographic, atmospheric and geomagnetic instrumentation and many scientists were associated with its findings and analysis, notably Harald Sverdrup, Roger Revelle and Scott Forbush (who escaped the fire that destroyed the sailing ship) when docked in Samoa in the South Pacific Ocean in November 1929). [8]
By 1930 the Department of Terrestrial Magnetism had enough data to be able to produce a much better view of Earth's magnetic field than had previously been available. [3] The loss of the sailing brigantine schooner / yacht Carnegie in 1929 after 20 years of work, left a void in the capability to collect oceanic magnetic data. By 1951 world magnetic charts were badly flawed. As a result the United States Navy Oceanographic / Hydrographic Office initiated the Navy's Project Magnet, an airborne program to collect additional magnetic data world wide. [9] The introduction of the proton precession magnetometer enabled magnetic data collection from steel-hulled ships routine by 1957 making the extreme measures used for Carnegie unnecessary. [10]
The atmospheric electrical measurements carried out aboard Carnegie are of enduring and fundamental importance in understanding the balance of electric current flow in the atmosphere, the system known as the global atmospheric electric circuit. Most significantly, the results showed that the atmospheric electric field—a quantity always present away from thunderstorms—shows a characteristic daily variation which was independent of the position of the ship. This is known as the Carnegie curve. [11]
RRS Discovery is a barque-rigged auxiliary steamship built in Dundee, Scotland for Antarctic research. Launched in 1901, she was the last traditional wooden three-masted ship to be built in the United Kingdom. Her first mission was the British National Antarctic Expedition, carrying Robert Falcon Scott and Ernest Shackleton on their first, and highly successful, journey to the Antarctic, known as the Discovery Expedition.
Jolie Brise is a gaff-rigged pilot cutter built and launched by the Albert Paumelle Yard in Le Havre in 1913 to a design by Alexandre Pâris. After a short career as a pilot boat, owing to steam replacing sail, she became a fishing boat, a racing yacht and a sail training vessel.
Te Vega is a two-masted, gaff-rigged auxiliary schooner. Originally launched as the Etak, she was designed by New York naval architects Cox & Stevens in 1929 for American businessman Walter Graeme Ladd and his wife, Catherine ("Kate") Everit Macy Ladd. Etak was built at the Friedrich Krupp Germaniawerft shipyard in Kiel, Germany, and launched in 1930. During World War II she served the US Navy as Juniata (IX-77). She is among the largest steel-hulled schooners afloat.
Zarya was a sailing-motor schooner built in 1952, and since 1953 used by the USSR Academy of Sciences to study Earth's magnetic field.
The first USS Patuxent was a fleet tug in commission in the United States Navy from 1909 to 1924. She served the United States Atlantic Fleet and saw service in World War I. After the end of her Navy career, she was in commission in the United States Bureau of Fisheries from 1926 to 1932 as the fisheries research ship USFS Albatross II.
USS California (SP-249) was a yacht acquired by the United States Navy during World War I and outfitted as an armed section patrol vessel patrolling New York waterways. Later, renamed the original name of Hauoli, it was assigned to Thomas A. Edison conducting underwater listening experiments related to antisubmarine warfare.
The Nimrod Islands were a group of islands first reported in 1828 by Captain Eilbeck of the ship Nimrod while sailing from Port Jackson around Cape Horn. Their reported location was east of Emerald Island and west of Dougherty Island, at approximately 56°S158°W. They are now considered phantom islands.
Scott Ellsworth Forbush was an American astronomer, physicist and geophysicist who is recognized as having laid the observational foundations for many of the central features of solar-interplanetary-terrestrial physics, which at the time was an underdeveloped field of study. In 1937 Forbush discovered the Forbush Effect: an occasional decrease in the intensity of cosmic rays as observed on Earth that is caused by the solar wind and its interaction with the magnetosphere. Scott conducted most of his research during his career at the Department of Terrestrial Magnetism (DTM) of the Carnegie Institution of Washington where he was appointed chairman of a section on theoretical geophysics in 1957. Forbush used statistical methods in analyses of magnetic storms, solar activity, rotation of the Earth, and the rotation of the sun, and the correlation of this geophysical and solar phenomena with temporal variations of cosmic-ray intensity.
USS Raeo (SP-588) was a United States Navy patrol vessel in commission from 1917 to 1919. Prior to her U.S. Navy service, she operated as the motor passenger vessel Raeo from 1908 to 1917. After the conclusion of her U.S. Navy career, she served as the fishery patrol vessel USFS Kittiwake in the United States Bureau of Fisheries fleet from 1919 to 1940 and as US FWS Kittiwake in the Fish and Wildlife Service fleet from 1940 to 1942 and from 1944 to at least 1945, and perhaps as late as 1948. During World War II, she again served in the U.S. Navy, this time as the yard patrol boat USS YP-199. She was the civilian fishing vessel Raeo from 1948 to 1957, then operated in various roles as Harbor Queen from 1957 to 1997. She became Entiat Princess in 1998 and as of 2009 was still in service.
Anton Dohrn was a motor yacht built during 1911 and delivered to the Carnegie Institution of Washington in June 1911 for use at its Department of Marine Biology laboratory at Dry Tortugas, Florida. The institution leased the vessel to the United States Navy for use as a patrol boat during World War I to serve as USS Anton Dohrn 5 October 1917 – 2 January 1919. The vessel remained in service for the institution until 1940 when Anton Dohrn was given to the Woods Hole Oceanographic Institution which used the vessel until 1947 for work between the Gulf of Maine and New Jersey. In 1947 the vessel was sold for use as a mail boat between New Bedford and Cuttyhunk Island.
Galilee was a brigantine, built in 1891, designed by Matthew Turner. She started on the packet line between San Francisco and Tahiti and was reckoned a very fast ship. In 1905 she was chartered by the Carnegie Institution's Department of Terrestrial Magnetism and converted into a magnetic observatory. She was used to make observations of Earth's magnetic field on three cruises over a period of three years from 1905 to 1908 in the Pacific Ocean.
Matthew Turner was an American sea captain, shipbuilder and designer. He constructed 228 vessels, of which 154 were built in the Matthew Turner shipyard in Benicia. He built more sailing vessels than any other single shipbuilder in America, and can be considered "the 'grandaddy' of big time wooden shipbuilding on the Pacific Coast."
