During the 1930s American engineers developed their own underwater sound detection technology and important discoveries were made, such as thermoclines, that would help future development.

Because speed and range were severely limited underwater while running on battery power, U-boats were required to spend most of their time surfaced running on diesel engines, diving only when attacked or for rare daytime torpedo strikes.

Whales were little understood for most of human history as they spend up to 90 % of their lives underwater, only surfacing briefly to breathe.

In 1987, researchers were able to tape, for the first time, an underwater birth ( as in the wild ) at the Toledo Zoo.

The underwater sequences were filmed in two specially constructed tanks.

The two working craft, Flatbed and Cab One, were specially manufactured for the film by Can-Dive Services Ltd., a Canadian commercial diving company that specialized in " saturation " diving systems and underwater technology.

The principal underwater sequences were shot by Al Giddings, known for his work on The Deep.

The only significant additions to the game's engine were the Jjaro ship, multiple paths between levels, a new rapid-fire weapon that could be used underwater, and vacuum-enabled humans carrying fusion weapons ( called " Vacuum Bobs " or " VacBobs ").

These submarines were known as the A-Class or Adder Class, and became America's first fleet of underwater craft at the beginning of the 20th century.

These and other early SLBM systems required vessels to be surfaced when they fired missiles, but launch systems eventually were adapted to allow underwater launching in the 1950-1960s.

The apparatuses, with steam propulsion, were completely inadequate for underwater navigation, and failed boisterously when sea trials were made by the respective navies that acquired them.

Eventually he became renowned for his ability to sustain his yodel for an unusually long time, a skill he reportedly learned while swimming underwater for several minutes at a time.

The underwater camera did not operate properly and the piranha were difficult to control, so Deodato reportedly dropped the scene.

Fishermen found a diver's slate ( a device used for communicating underwater ) and wrote down what it reportedly read: " nday Jan 26 ; 1998 08am.

In the early 1970s, a group of people led by Robert H. Rines obtained some underwater photographs.

The world's first patent for an underwater echo ranging device was filed at the British Patent Office by English meteorologist Lewis Richardson a month after the sinking of the Titanic, and a German physicist Alexander Behm obtained a patent for an echo sounder in 1913.

They dive for food from the surface, swimming underwater, feeding on benthic prey, which is usually obtained close to shore.

The project will be run through a local Rwandan entity called KivuWatt, using an offshore barge platform to extract, separate and clean the gasses obtained from the lake bed before pumping purified methane via an underwater pipeline to on-shore gas turbines (" gensets ").

But just before luncheon today the fact was announced grimly by the British navy's chief adviser to the cabinet on underwater warfare, Capt. George Symonds.

The amphibious salamander Ensatina attaches its similar clusters by stalks to underwater stems and roots.

The demand for ormers is such that they led to the world's first underwater arrest, when Mr. Kempthorne-Leigh of Guernsey was arrested by a police officer in full diving gear when illegally diving for ormers.

Its holding power is defined by its weight underwater ( i. e. taking its buoyancy into account ) regardless of the type of seabed, although suction can increase this if it becomes buried.

There is also an underwater statue of the Virgin of Guadalupe here, created in 1958 by Armando Quesado in memory of a group of divers that died here.

Submarine channels are similar to land rivers, but they are formed by density currents — underwater flow mixtures of sand, mud and water that are denser than sea water and so sink and flow along the bottom.

The record for the largest continuously placed underwater concrete pour was completed 18 October 2010, in New Orleans, Louisiana by contractor C. J. Mahan Construction Company, LLC of Grove City, Ohio.

The Dominican Republic's small Catalina Island has been studied since 13 December 2007, by a team of underwater archaeologists from Indiana University, after an Italian tourist announced the discovery of an old wreck at just under the clear blue waters, at a distance of no more than offshore.

A small amount of additional tuning is available by ' entry save ' techniques, whereby underwater movements of the upper body and arms against the viscosity of the water affect the position of the legs.

By the end of the 19th century the world had been forever changed by the rapid communication made possible by engineering development of land-line, underwater and, eventually, wireless telegraphy.

Mangroves along the shore make shrimp and shellfish particularly abundant by providing safe and abundant breeding areas amid their extensive networks of underwater roots.

The two neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943, for the first French underwater film: Par dix-huit mètres de fond ( 18 meters deep ), made without breathing apparatus the previous year in the Embiez islands ( Var ) with Philippe Tailliez and Frédéric Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Léon Vèche ( engineer of Arts and Métiers and the Naval College ).

According to his first book, The Silent World: A Story of Undersea Discovery and Adventure ( 1953 ), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur.

Cousteau was not satisfied with the length of time he could spend underwater with the Le Prieur apparatus so he improved it to extend underwater duration by adding a demand regulator, invented in 1942 by Émile Gagnan.

Although it was never able to match the number of ships of the Royal Navy, it had technological advantages, such as better shells and propellant for much of the Great War, meaning that it never lost a ship to a catastrophic magazine explosion from an above-water attack, although the elderly pre-dreadnought Pommern sank rapidly at Jutland after a magazine explosion caused by an underwater attack.
