	Decompression stop - Wikipedia, the free encyclopedia
		Typically with tables, the maximum ascent rate is 30 feet (10 metres) per minute when deeper than 20 feet (6 metres).
		When diving with nitrogen based breathing gases, decompression stops are typically carried out in the 10 to 65 feet (3 to 20 metres) depth range.
		A diving shot, a surface marker buoy or a decompression buoy can be used to mark the underwater positions and act as a buoyancy control aid in low visibility or currents.

	Decompression sickness -- Facts, Info, and Encyclopedia article (Site not responding. Last check: 2007-10-08)
		Decompression sickness, DCS, the bends, dysbarism, or caisson disease describes a condition characterized by a variety of symptoms resulting from exposure to barometric pressure which is getting lower.
		When the body is exposed to decreased barometric pressures (as in flying an unpressurized aircraft to altitude, or during a rapid decompression), the nitrogen dissolved in the body comes out of solution.
		This table lists the different DCS types with where the bubbles form and their most common symptoms.

	Science Fair Projects - Dive computer
		A dive computer or decompression meter is an electronic device used by a scuba diver to measure the dive profile and to display information needed for a safe dive, avoiding decompression sickness.
		Dive computers address the same problem as decompression tables, but perform a continuous calculation of the partial pressure of gases in the body based on the actual dive profile.
		Most dive computers calculate decompression for 'open circuit' SCUBA where the proportions of the breathing gases are constant: these are "constant fraction" dive computers.

		Tables from Brazil, France, Germany, Holland, Switzerland and USA are included together with the UK tables which are the Blackpool Tables using oxygen from 0.6 bar.
		There are two main conclusions from this study: that the Blackpool Tables are predicted to have a volume of gas carried in bubbles which is within the range of that for the other tables studied.; that the other tables studied could all be considered acceptable for use in UK.

	Bubble Decompression Strategies
		While this might be the objective of all decompression schedules, the surprising result is that bubble elimination strategies are often contrary to the recommendations of traditional diving tables and therefore seem counter-intuitive.
		For instance, decompression stops called for by bubble models are much deeper (often within a few ata of bottom) than corresponding neo-Haldane tables.
		Hills believed that the USN's tables encouraged formation of bubbles via a long ascent to a relatively shallow first stop and that the long ten-foot stop served as therapy to reduce bubbles formed by the extreme first pull upward.

	Ascending From A Dive (ascent rates, deep safety/deco stops & time limits)
		However, the majority of dive tables (not all) use slower ascent rates and 10 meters (33 feet) per minute is common in other countries.
		Brian Hill's thermodynamic decompression ideas got me into this line of thinking and this slower ascent rate has its advantages and is used in Departure.
		Many divers look at only the time limits at the deeper depths when evaluating tables and will notice a difference of 1 to 2 minutes at 130 feet, but do not notice a difference of 60 minutes or greater at 35 feet – which may actually be the more critical measurement.

	The Ultimate Altitude diving - American History Information Guide and Reference (Site not responding. Last check: 2007-10-08)
		Altitude diving is significant in recreational diving because the decompression stops used for dives at altitude are different from those used for the same dive profile at sea level.
		Decompression sickness is caused by the absorption and release of inhaled gases under differing pressure environments and changes of pressure.
		Normally dive computers detect changes in altitude and automatically adjust their calculation of a safe decompression regime for a dive at that altitude.

		This repeat dive table itself replaced an older rule of thumb of "deepest depth/total time", in which successive dives gradually used up the bottom time appropriate for the deepest dive (which should have been the first).
		The 88 Tables were designed specifically for sports diving, in particular making the planning of repeat dives simpler and subsequently introducing the altitude tables.
		The BS-AC commissioned Tom Hennessy to produce the 88 tables which, if I remember correctly, were a remodelling of original RN data.

	Development and Validation of 1.3 ATA PO2-in-He Decompression Tables for the MK 16 MOD 1 UBA - Storming Media
		Abstract: The Navy Experimental Diving Unit (NEDU) was tasked by PMS-EOD to develop and validate repetitive helium-oxygen (He-O2) decompression tables for use with the MK 16 MOD 1 Underwater Breathing Apparatus (UBA).
		The report includes a description of the probabilistic model used as the basis for the tables, and presents a novel method to map this model to an easily-used deterministic model.
		The latter produces a repetitive decompression table set of format similar to that for standard air diving in the current U.S. Navy Diving Manual, but with schedules that incur explicitly controlled estimated DCS risks.
