The Sawfish harvester is a submersible robot produced by the Triton Logging Inc. It is designed for cutting down submerged trees and popping them to the surface, with large pincers and a chainsaw. Such trees are generally submerged when dams are built near existing forests, and their wood remains good while underwater for long periods.

Sawfish is a window manager for the X Window System. It aims to manage windows in the most flexible and attractive manner possible. It is able to match a window by multiple criteria such as application, size or role, and based on this, can change the window's position, appearance, or behavior. This allows for highly customized window handling such as web browser windows opening full-screen without borders on a secondary monitor, a default terminal emulator window displaying full-screen at the desktop level, and all dialog box windows under a certain size opening on the lower right corner of the main monitor while larger ones are centered.
USS Triton (SSRN/SSN-586) was a United States Navy radar picket nuclear submarine. In early 1960, it became the first vessel to execute a submerged circumnavigation of the Earth in Operation Sandblast. Triton accomplished this objective during her shakedown cruise while under the command of Captain Edward L. "Ned" Beach Jr. She was the only member of her class and had the distinction of being the only Western submarine powered by two nuclear reactors.
Seaview, a fictional nuclear submarine, was the setting for the 1961 motion picture Voyage to the Bottom of the Sea, starring Walter Pidgeon, and later for the 1964–1968 ABC television series of the same title. In the film, Seaview fires a ballistic missile with a nuclear warhead to extinguish the Van Allen belt that was set on fire by a space cataclysm.
A Sawfish is a large, endangered cartilaginous fish with a saw-shaped nose.
Edward Latimer Beach Jr. was a highly decorated United States Navy submarine officer and best-selling author.
Sawfish, also known as carpenter sharks, are a family of rays characterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged in a way that resembles a saw. They are among the largest fish with some species reaching lengths of about 7–7.6 m (23–25 ft). They are found worldwide in tropical and subtropical regions in coastal marine and brackish estuarine waters, as well as freshwater rivers and lakes. They are also endangered.
USS Sawfish (SS-276), a Gato-class submarine, was a ship of the United States Navy named for the sawfish, a viviparous ray which has a long flat snout with a row of toothlike structures along each edge. It is found principally in the mouths of tropical American and African rivers.
Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe, a German-born British engineer chiefly known for his contributions to diving equipment.
The Triton Light is a navigational beacon on the seawall of the United States Naval Academy in Annapolis, Maryland, where the Severn River meets Spa Creek and the Annapolis harbor. It was donated to the Academy and named for the Greek god by the Class of 1945. It is not only an important part of the culture and traditions of the Naval Academy, but also is a trusted navigational point in Annapolis Harbor.
The S4G reactor is a naval reactor used by the United States Navy to provide electricity generation and propulsion on warships. The S4G designation stands for:
The narrow sawfish(Anoxypristis cuspidata), also known as the pointed sawfish or knifetooth sawfish, is a species of sawfish in the family Pristidae, part of the Batoidea, a superorder of cartilaginous fish that include the rays and skates. Sawfish display a circumglobal distribution in warm marine and freshwater habitats. Their extant biodiversity is limited to five species belonging to two genera. The sawfishes are characterised by the long, narrow, flattened rostrum or extension on their snout. This is lined with sharp transverse teeth, arranged in a way that resemble the teeth of a saw and are used for killing prey. It is found in the shallow coastal waters and estuaries of the Indo-West Pacific, ranging from the Red Sea and the Persian Gulf to southern Japan, Papua New Guinea and northern Australia. It is the only living member of the genus Anoxypristis, but was previously included in the genus Pristis. Compared to Pristis, Anoxypristis has a narrower rostral saw with numerous teeth on the distal part and no teeth on the basal one-quarter. This endangered species reaches a length of up to 3.5 m (11 ft).
The largetooth sawfish is a species of sawfish, family Pristidae. It is found worldwide in tropical and subtropical coastal regions, but also enters freshwater. It has declined drastically and is considered critically endangered.
The smalltooth sawfish is a species of sawfish in the family Pristidae. It is found in shallow tropical and subtropical waters in coastal and estuarine parts of the Atlantic. Reports from elsewhere are now believed to be misidentifications of other species of sawfish. It is a critically endangered species that has disappeared from much of its historical range.
The longcomb sawfish, narrowsnout sawfish or green sawfish is a species of sawfish in the family Pristidae, found in tropical and subtropical waters of the Indo-West Pacific. It has declined drastically and is now considered a critically endangered species.
Shakedown cruise is a nautical term in which the performance of a ship is tested. Generally, shakedown cruises are performed before a ship enters service or after major changes such as a crew change, repair or overhaul. The shakedown cruise simulates working conditions for the vessel, for various reasons. For most new ships, the major reasons are to familiarise a crew with a new vessel and to ensure all of the ship's systems are functional.
Underwater logging is the process of logging trees from underwater forests. When artificial reservoirs and dams are built, large areas of forest are often inundated; although the trees die, the wood is often preserved. The trees can then be felled using special underwater machinery and floated up to the surface. One such machine is the sawfish harvester. There is an ongoing debate to determine whether or not underwater logging is a sustainable practice and if it is more environmentally sustainable than traditional logging.
On the Beach is a 1959 American post-apocalyptic science fiction drama film from United Artists, produced and directed by Stanley Kramer, that stars Gregory Peck, Ava Gardner, Fred Astaire, and Anthony Perkins. This black-and-white film is based on Nevil Shute's 1957 novel of the same name depicting the aftermath of a nuclear war. Unlike in the novel, no one is assigned blame for starting the war; the film hints that global annihilation may have arisen from an accident or misjudgment.
Pristis is a genus of sawfish of the family Pristidae. These large fish are found worldwide in tropical and subtropical regions in coastal marine waters, estuaries, and freshwater lakes and rivers. Sawfish have declined drastically and all species are considered seriously threatened today.
Operation Sandblast was the code name for the first submerged circumnavigation of the world, executed by the United States Navy nuclear-powered radar picket submarine USS Triton (SSRN-586) in 1960 under the command of Captain Edward L. Beach Jr.
