What is the history behind Alvin’s name?
Alvin, the first U.S. research submersible , was commissioned on June 5, 1964, at the Woods Hole Oceanographic Institution in Massachusetts. ... Alvin was named for its primary inspiration, the engineer and geophysicist Allyn Vine.
What does Alvin mean in science?
Human Occupied Vehicle (HOV) Alvin is part of the National Deep Submergence Facility (NDSF). Alvin enables in-situ data collection and observation by two scientists to depths reaching 4,500 meters, during dives lasting up to ten hours.
What is Alvin submarine?
The “Alvin” submarine – named for famous oceanographer Allyn Vine – became the world’s premiere deep-diving research vessel when it was deployed by the Woods Hole Oceanographic Institute in 1964. The 23-foot sub has been a workhorse – and is still making history after more than 50 years.
What did the Alvin Do?
In 1977 scientists in Alvin discovered low temperature (~20 °C) vents on the Galapagos spreading center east of those same islands. During the RISE expedition in 1979 scientists using Alvin discovered high temperature vents (380 °C) popularly known as ‘black smokers’ on the crest of the East Pacific Rise at 21° N.
What is a human occupied vehicle?
Human Occupied Vehicles (HOVs) take small teams of scientists and engineers directly to the seafloor for limited periods of time . ... Remotely Operated Vehicles (ROVs) are tethered robots that allow researchers to make observations, collect samples, and conduct experiments while controlling the vehicle from the surface.
Who piloted the Alvin?
Pilots Bill Rainnie and Marvin McCamis made the first several dives. There were a total of 77 shallow, tethered dives in or near Woods Hole to maximum depths of 70 feet, with the first free dive of the submersible taking place on Aug. 4, 1964 to 35 feet.
Who is Alvin’s girlfriend?

How deep can ROVS go?
ROV SuBastian can go down to a maximum operating depth of 4,500 meters and transit at a speed of 0.5 – 3 knots, depending on depth and currents.
How much did the Alvin cost?
Alvin, which has undergone nearly continuous upgrades since its launch in 1964, dives to 4,500 meters (14,764 feet). The four-year design and construction project is expected to cost $21.6 million and will be funded largely by NSF.
What are deep sea submarines made of?
a three-person crewed DSV. The hull is made of inox steel and it has a large 1,200-millimetre-diameter (47 in) semi-spheric acrylic glass viewport. It is designed to reach depths of 1,200 metres (3,900 ft), thus being the ninth-deepest submersible, and it is capable of diving during 10 hours using li-ion batteries.
How did the bathysphere work?
Bathysphere, spherical steel vessel for use in undersea observation , provided with portholes and suspended by a cable from a boat. Built by the American zoologist William Beebe and the American engineer Otis Barton, the bathysphere made its first dives in 1930.
How are ROVs controlled?
These underwater machines are controlled by a person typically on a surface vessel , using a joystick in a similar way that you would play a video game. ... Most ROVs are equipped with at least a still camera, video camera, and lights, meaning that they can transit images and video back to the ship.
