	DAN Divers Alert Network : How Deep is Too Deep?
		Deep diving demands vast amounts of knowledge, experience and discipline, as well as appropriate preparation and equipment, since deep diving is fraught with potential hazards.
		Some divers routinely dive to depths in excess of 165 feet/50 meters on air, although over recent years gas mixtures such as heliox and trimix have become far more commonly used for very deep diving as they are less narcotic.
		The depth of the onset of the effects of the exotic cocktail of elevated pressures of nitrogen, carbon dioxide and oxygen, coupled with the sensory deprivation and stress associated with diving, are not always predictable.

		All groups, whether diving from a boat or from shore, are required to fly a diver down flag (a red flag with a white diagonal slash) to alert boaters that people are underwater.
		Diving equipment depends on the location of the dive, but whether scuba diving or snorkeling, recreational divers need several basic items: a mask, a snorkel, fins, and, when necessary, an exposure suit to remain warm.
		Emergency equipment includes a dive knife, in case the diver becomes entangled in fishing line or marine plants, and whistles, lights, or signaling devices, in case the diver is lost or swept out in a current.

	Scientific American: How do deep-diving sea creatures withstand huge pressure changes?
		Routine dive depths are usually in the 1,500- to 3,000-foot range, and dives can last between 20 minutes and an hour.
		Diving to depth can result in mechanical distortion and tissue compression, especially in gas-filled spaces in the body.
		This blunting of gas exchange is important in the deep diver because it prevents the absorption of nitrogen into the blood and the subsequent development of high blood nitrogen levels.

	Diving Lore \| Technical Diving
		Technical diving started out in the late 1970s and was the result of a growing number of recreational divers who felt hampered by the conservative limits imposed on them by the mainstream diving community.
		Deep diving techniques, modified decompression models (inc. deep stops) for the mixed gases used, the ways of dealing with potentially lethal situations at extreme depths and overcoming them.
		By the 1990s the technical divers were establishing themselves fully in the diving community, this is partly because many of the technical dive schools became established at this time and partly because they saw that a niche was there for technical divers.

		The wreck was rediscovered in 1963 and photos from the early dives on this still popular dive show the incredible types of artifacts a diver could recover from a shipwreck during these early freewheeling times.
		One of the deep shipwreck diving areas, Whitefish Point (Lake Superior), was to see the clash of two cultures in the mid 90’s, as young divers showed up with more money in their “dive rigs” than a lot of the older guys had invested in their dive boats.

	Technical Diving
		Technical diving is a phrase coined to identify advanced levels of scuba diving where mixed gases are utilised to overcome physiological and decompression problems of deep and extended diving.
		A technical dive may be that of a deep wreck where a mixture of gas other than standard scuba air is to be used or on the other hand it could be one of a serious cave penetration that substitutes air for Nitrox to benefit from lengthy periods in shallow water.
		Deep Blue diving have trained many of today's well known technical divers and offer the training from the basic nitrox courses through to advanced mixed gas closed circuit rebreather diver.

		Deep-sea diving is an activity in which a person can descend beyond the recreational scuba diving limit of 40 m (130 ft).
		Diving scientists geologists, biologists, ecologists, physiologists, and archaeologists use deep-sea diving techniques and equipment both for profit and to further humanity's knowledge about the planet Earth.
		On some such jobs, divers are kept at dive-depth pressures in surface chambers for up to 60 days, then are delivered to the dive site by means of a diving bell that limits their exposure to the water and provides a measure of comfort and protection during the long descent and ascent.
