Alvin (DSV-2) is a crewed deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) of Woods Hole, Massachusetts. The original vehicle was built by General Mills' Electronics Group in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, Alvin was commissioned on June 5, 1964.
A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds. The bulk of the displacement necessary to keep the ship afloat is located beneath the waves, where it is less affected by wave action. Wave excitation drops exponentially as depth increases, so wave action normally does not affect a submerged submarine at all. Placing the majority of a ship's displacement under the waves is similar in concept to creating a ship that rides atop twin submarines.
A research vessel is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters.
BRP Gregorio Velasquez is Philippine Navy's first oceanographic research vessel. It was built by the United States Navy as USNS Melville (T-AGOR-14) for university support of Navy programs. The ship was operated as the research vessel R/V Melville by the Scripps Institution of Oceanography for oceanographic research. As the R/V Melville, it was the oldest active vessel in the academic research fleet, collectively known as the University-National Oceanographic Laboratory System (UNOLS) (UNOLS). The US Government confirmed on 17 November 2015 that the Melville was to be transferred to the Philippine Navy as Excess Defense Articles (EDA)s. The vessel was officially transferred to the Philippines on 28 April 2016 and was commissioned into active service at the same time with the Philippine Navy.
RV Atlantis is a Thomas G. Thompson-class oceanographic research ship, owned by the US Navy and operated by the Woods Hole Oceanographic Institution as part of the University-National Oceanographic Laboratory System (UNOLS) fleet. She is the host vessel of DSV Alvin. She is named for the first research vessel operated by WHOI, the sailboat RV Atlantis, for which the Space ShuttleAtlantis is also named.
RV Knorr was a research vessel formerly owned by the U.S. Navy and operated by the Woods Hole Oceanographic Institution for the U.S. research community in coordination with and as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet. On March 14, 2016, Knorr was officially transferred to the Mexican Navy and renamed Rio Tecolutla. She was replaced at Woods Hole by the RV Neil Armstrong. Knorr is best known as the ship that supported researchers as they discovered the wreck of the RMS Titanic in 1985. R/V Knorr (AGOR-15) has traveled more than a million miles—the rough equivalent of two round trips to the Moon or forty trips around the Earth. Her sister ship is the RV Melville.
RV Oceanus is a Regional-class research vessel owned by the National Science Foundation, based in Newport, Oregon, and maintained and operated by Oregon State University. The ship was originally delivered to the Woods Hole Oceanographic Institution (WHOI) for operation as a part of the U.S. Academic Research Fleet as a University-National Oceanographic Laboratory System (UNOLS) designated operator. in November 1975. Oceanus made the first operational cruise in April 1976 and operated under WHOI for thirty-six years in the Atlantic Ocean with some operations in the Mediterranean and Caribbean seas. The ship was scheduled to be retired in November 2011 but instead was transferred to Oregon State University, College of Earth, Ocean, and Atmospheric Sciences, for operation, replacing sister ship, {{RV|Wecoma]}.
RV Roger Revelle is a Thomas G. Thompson-class oceanographic research ship operated by Scripps Institution of Oceanography under charter agreement with Office of Naval Research as part of the University-National Oceanographic Laboratory System (UNOLS) fleet. The ship is named after Roger Randall Dougan Revelle, who was essential to the incorporation of Scripps into the University of California San Diego.
RV Thomas G. Thompson (AGOR-23) is an oceanographic research vessel and lead ship of her class, owned by the United States Office of Naval Research and operated under a bareboat charterparty agreement by the University of Washington as part of the University-National Oceanographic Laboratory System (UNOLS) fleet.
A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth. Unlike other sonars and echo sounders, MBES uses beamforming to extract directional information from the returning soundwaves, producing a swathe of depth soundings from a single ping.
USS Chain (ARS-20/T-AGOR-17) was a Diver-class rescue and salvage ship commissioned by the U.S. Navy during World War II. Her task was to come to the aid of stricken vessels.
USS Snatch (ARS-27), well known as Scripps RV Argo after conversion to scientific research, was a Diver-class rescue and salvage ship commissioned by the U.S. Navy during World War II and in service from 11 December 1944 through 23 December 1946. Her task was to come to the aid of stricken vessels. The ship is better known from her scientific research role as the Scripps Institution of Oceanography (SIO) research vessel RV Argo. It is that name, apparently not formally recognized by Navy that maintained title to the vessel, found in the scientific literature and public releases about her wide ranging research voyages.
USNS James M. Gilliss (T-AGOR-4) was a Robert D. Conrad-class oceanographic research ship acquired by the U.S. Navy in 1962. The ship was operated by the Military Sea Transportation Service and managed by the Naval Oceanographic Office as one of the "Navy Pool" vessels serving various Navy laboratories and projects in the Atlantic Ocean. After active Navy pool service the ship was assigned to the University of Miami to operate as part of the University-National Oceanographic Laboratory System (UNOLS) fleet until 1979.
Thomas G. Thompson (T-AGOR-9) was a Robert D. Conrad-class oceanographic research ship acquired by the U.S. Navy in 1965. The ship was transferred to the University of Washington for operation as part of the University-National Oceanographic Laboratory System (UNOLS) fleet on 21 September 1965. In 1988 the ship went out of UNOLS service. The ship, retaining the previous name, was designated by the Navy as IX-517 assigned to the Mare Island Naval Shipyard for general naval research. Thomas G. Thompson was later renamed Pacific Escort II with the same designation. On 7 May 1997 the Navy renamed the ship Gosport and transferred the ship to the Norfolk Naval Shipyard available for hire as a multi purpose platform from the shipyard. The ship, placed out of service and struck from the register on 27 February 2004, was sunk as part of a NATO exercise 14 November 2004.
Thomas Washington (T-AGOR-10) was a Robert D. Conrad-class oceanographic research ship delivered to the U.S. Navy in 1965. The ship was owned by the Navy but assigned to the Scripps Institute of Oceanography, University of California, La Jolla, California and operated as R/VThomas Washington from delivery to inactivation.
Gyre (T-AGOR-21), best known as RV Gyre, was the lead ship of her class of oceanographic research ships acquired by the U.S. Navy in 1973 for assignment to the University-National Oceanographic Laboratory System (UNOLS) fleet of Navy owned ships. Gyre was operated by the Texas A&M University School of Oceanography as part of the Navy owned UNOLS fleet until stricken 17 August 1992 and transferred to the university under a program transferring ships to states, schools and other public institutions. The university operated the ship until sale in December 2005.
The University-National Oceanographic Laboratory System (UNOLS) is a group of academic institutions and National Laboratories organized in the United States to coordinate research vessel use for federally funded ocean research.
