Grandad, stately and retired, represents Edwardian graciousness, for which Mr Osborne has a deeply submerged nostalgia.

The bubbling waters were only ten or twenty yards below, the steam was much hotter, and the red glow of deeply submerged lava brighter.

The wave particle velocity reduces with water depth and is therefore less of an issue for deeply submerged turbines.

A submarine also has the option of floating a long, buoyant wire antenna to a shallower depth, allowing VLF transmissions by a deeply submerged boat.

Wave excitation drops exponentially as depth increases (Deeply submerged submarines are normally not affected by wave action at all).

A surface ROV can move on its own and scan below itself with sonar, but without a long-range weapon it can do little against deeply submerged suspect divers.

A surface-only ROV would need a long-range weapon to be effective against deeply submerged suspect divers.

Halfway around the world it now extended, its narrow fans of radiation reaching up to the surface from the deeply submerged generators.

Communicating with deeply submerged submarines by radio was once virtually impossible, but experiments in the 1950's demonstrated that a particular kind of radio signal could offer a communications link.

At some deeply submerged level of mind, Ryan recognized the alien nature of the thought and recoiled.

However, most drug subs so far are not as sophisticated as professional merchant submarines would be, being mainly intended to run just under the surface, rather than deeply submerged.

The power generation equipment is similar to that of a wind turbine and is housed in the cylindrical shaped watertight lower hull, which is deeply submerged below the water line and supported by small waterplane area surface piercing struts.

Zealandia separated from Australia 60-85 million years ago, and the ridge linking New Caledonia to New Zealand has been deeply submerged for millions of years.

Unlike many of the Pacific Islands, which are of relatively recent volcanic origin, New Caledonia is part of Zealandia, a fragment of the ancient Gondwana that separated from Australia 60-85 million years ago, and the ridge linking New Caledonia to New Zealand has been deeply submerged for millions of years.

"The reason for doing this is probably deeply submerged in my own personality - something to do with my own obsessions," he said.

Hints of their former selves occasionally appear in the glowing shapes of beer mugs and pianos, but these are deeply submerged in abstract forms.

The eastern portion of the reef is deeply submerged.

A generation ago, Paul Benacceraf, an influential philosopher at Princeton University, raised a famous challenge asking how, if mathematical knowledge stands outside of space and time, it can be reached from an earthly realm deeply submerged in space and time.

But most important, the fourth dimensional awareness, the complete picture of the Arrow of Time and his position on it which is born in every man but deeply submerged by the trivia of living, was in Foyle close to the surface.
