Bathysphere
The Bathysphere (Greek: , , "deep" and , , "sphere") was a unique spherical deep-sea submersible which was unpowered and lowered into the ocean on a cable, and was used to conduct a series of dives off the coast of Bermuda from 1930 to 1934. The Bathysphere was designed in 1928 and 1929 by the American engineer Otis Barton, to be used by the naturalist William Beebe for studying undersea wildlife. Beebe and Barton conducted dives in the Bathysphere together, marking the first time that a marine biologist observed deep-sea animals in their native environment. Their dives set several consecutive world records for the deepest dive ever performed by a human. The record set by the deepest of these, to a depth of on August 15, 1934, lasted until it was broken by Barton in 1949. Origin and design In 1928, the American naturalist William Beebe was given permission by the British government to establish a research station on Nonsuch Island, Bermuda. Using this station, Beebe planned to ...

William Beebe
Charles William Beebe ( ; July 29, 1877 – June 4, 1962) was an American naturalist, ornithologist, marine biologist, entomologist, explorer, and author. He is remembered for the numerous expeditions he conducted for the New York Zoological Society, his deep dives in the Bathysphere, and his prolific scientific writing for academic and popular audiences. Born in Brooklyn, New York and raised in East Orange, New Jersey, Beebe left college before obtaining a degree to work at the then newly opened New York Zoological Park, where he was given the duty of caring for the zoo's birds. He quickly distinguished himself in his work for the zoo, first with his skill in designing habitats for its bird population, and soon also with a series of research expeditions of increasing length, including an expedition around the world to document the world's pheasants. These expeditions formed the basis for a large quantity of writing for both popular and academic audiences, including an acc ...

Gloria Hollister
Gloria Hollister Anable (June 11, 1900 – February 19, 1988) was an American explorer, scientist, and conservationist. She served as research associate in the Department of Tropical Research of the New York Zoological Society (now the Wildlife Conservation Society), specializing in fish osteology, and she made record-setting dives in a submersible called the Bathysphere off the coast of Bermuda in the 1930s. During the 1950s, she helped to found the committee that preserved that Mianus River Gorge, which subsequently became the Nature Conservancy’s first land project. Early life Gloria Elaine Hollister was born to Elaine Shirley Hollister and Dr. Frank Canfield Hollister in the family's home at 264 West 77th Street in New York City. The home also served as the office and laboratory of Dr. Hollister, a physician and diagnostician who attended Physicians and Surgeons College at Bellevue Hospital. Through both of her parents, Gloria Hollister was of notable early American ancestr ...

Bathysphaera
An illustration based on Else Bostelmann's reconstruction "''Bathysphaera intacta''", the "giant dragonfish" is species of fish that was described by William Beebe on 22 September 1932, being spotted by the biologist as he descended to a depth of 640 metres (2100 feet) of the coast of Bermuda . Background The "bathysphere", as termed by Beebe, was a new invention, a rounded steel enclosure with space adequate for two people. On the side, there was a single window, fifteen centimetres across. Having no camera equipment on the 1930 to 1934 dives, Beebe described observations in detail to Else Bostelmann, an artist who proceeded to illustrate the descriptions. The encounter Beebe encountered two fish, which he had described as "six feet long". He said they resembled barracudas, with short heads and jaws that were constantly opened. The fish expressed bioluminescence, as stated by him: "strong lights, pale bluish, was strung down the body". Bebe then expressed his justification ...

Otis Barton
Frederick Otis Barton Jr. (June 5, 1899 – April 15, 1992) was an American deep-sea diver, inventor and actor. Early life and career Born in New York, the independently wealthy Barton designed the first bathysphere and made a dive with William Beebe off Bermuda in June 1930. They set the first record for deep-sea diving by descending . In 1934, they set another record at . Barton acted in the 1938 Hollywood movie, '' Titans of the Deep''. Later career In 1949, Barton set a new world record with a 4,500 foot (1,372 m) dive in the Pacific Ocean, using his benthoscope (from the Greek ''benthos'', meaning 'sea bottom', and ''scopein'', 'to view'), which was designed by Barton and Maurice Nelles. Barton wrote the book ''The World Beneath the Sea'', published in 1953. Like Beebe, Barton was also interested in exploring tropical rain forests, and spent considerable time in places like Gabon. In 1978, Barton successfully tested a "jungle spaceship" (actually an airship ...

Submersible
A submersible is a small watercraft designed to operate underwater. The term "submersible" is often used to differentiate from other underwater vessels known as submarines, in that a submarine is a fully self-sufficient craft, capable of independent cruising with its own power supply and air renewal system, whereas a submersible is usually supported by a nearby surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word "submarine" may be used to describe a craft that is by the technical definition actually a submersible. There are many types of submersibles, including both crewed and uncrewed craft, otherwise known as remotely operated vehicle A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the a ...s (ROVs) or ...

Else Bostelmann
Else Winkler von Röder (Roeder) Bostelmann (1882-1961), a German-born American artist, joined the New York Zoological Society (now the Wildlife Conservation Society) in 1929 to paint marine life during William Beebe's bathysphere oceanographic expeditions at Bermuda's Nonsuch Island (1930-1934). Bostelmann's marine life paintings depicted the unbelievable sights that Beebe encountered from great depths in the ocean. "Had it not been for Mrs. Bostelmann's deftness in rapidly sketching what she saw, much of the color and drama would have been lost." Bostelmann, born in Leipzig, Germany, attended private schools and spent her childhood in Germany and Austria. Prior to her marriage in 1909 to Monroe Bostelmann (1881-1920), she studied at the University of Leipzig and the Grand Ducal Academy in Weimar receiving a Gold Medal for drawing. In addition to the Königliche Akademie of Graphic Arts in Leipzig, Bostelmann studied with the well-known Russian artist Sascha Schneider (1870-192 ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally air or water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical li ...

Stuffing Box
A stuffing box or gland package is an assembly which is used to house a gland seal. It is used to prevent leakage of fluid, such as water or steam, between sliding or turning parts of machine elements. Components A stuffing box of a sailing boat will have a stern tube that is slightly bigger than the prop shaft. It will also have packing nut threads or a gland nut. The packing is inside the gland nut and creates the seal. The shaft is wrapped by the packing and put in the gland nut. Through tightening it onto the stern tube, the packing is compressed, creating a seal against the shaft.Stuffing Box Maintenance

Frequencies
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as ''temporal frequency'' for clarity, and is distinct from ''angular frequency''. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the interval of time between events, so the period is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times a minute (2 hertz), the period, —the interval at which the beats repeat—is half a second (60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. Definitions and units For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term ''frequency'' is defined as the number of cycles or vibrations per unit of time. ...
