snorkel

Borrowed from German Schnorchel (“(submarine) snorkel”), related to schnarchen (“to snore”).

Watson, "New Epoch in Sea War", The Baltimore Sun, December 31, 1945, p. 8: "The Germans' earlier quest of the last important objective, it will be remembered, had produced the Snorkel, a long exhaust tube whose vent reached above water and permitted a submerged vessel to discharge its Diesel fumes in open air."

nitrox

Blend of nitro(gen) + ox(ygen). Analyzable as nitro- + ox

"Enriched air" or "nitrox" is a mixture of air and oxygen; the oxygen component ranges to about 50% but is used normally at 32 to 40%. [...] Safe enriched air nitrox diving practices established for the scientific diving community might be of some value and could help avoid accidents due to ignorance of its hazards and use of improper procedures.

1989 September, “Abstract”, in R. W. Hamilton, Dudley J. Crosson, Alan W. Hulbert, editors, Workshop on Enriched Air Nitrox Diving (National Undersea Research Program Research Report; 89-1), Rockville, Md.: Office of Undersea Research, Oceanic and Atmosphere Research, National Oceanic and Atmospheric Administration, U.S. Department of Commerce, →OCLC, page 1:

NOAA Nitrox I is a standard breathing gas mixture of 32% oxygen (±1%); the balance of the gas (68%) is nitrogen. [...] High-pressure storage cylinders, scuba tanks, regulators, and all high-pressure gas transfer equipment that is used with pure oxygen or with nitrox mixtures that contain more than 40 percent oxygen must be cleaned and maintained for oxygen service.

1991 October, “Appendix D: NOAA Nitrox I Diving and Decompression Tables”, in NOAA Diving Manual: Diving for Science and Technology, Silver Spring, Md.: Office of Undersea Research, Oceanic and Atmosphere Research, National Oceanic and Atmospheric Administration, U.S. Department of Commerce, →OCLC, page D-1:

Is there a compromise between too much oxygen and too much inert gas? The answer is the use of enriched air nitrox (enriched air) mixtures in the SCUBA tank. The two most commonly used mixtures are 32 percent and 36 percent oxygen mixtures. [...] [T]he increased oxygen percentages make the diver using nitrox mixtures more subject to oxygen seizures. With nitrox mixtures, the relative increase in oxygen percentage is over three times the relative decrease in nitrogen percentage.

2004, Michael B. Strauss, Igor V. Aksenov, Diving Science, Champaign, Ill.: Human Kinetics, →ISBN, page 35:

[N]itrox is often referred to as ‘enriched air’ or ‘enriched air – nitrox’ (EANx). By convention, the mix is described by reference to its oxygen content. Thus, if a nitrox mix contains 36 per cent oxygen, then it is referred to as ‘nitrox 36’ (‘Nx36’) or ‘EANx36’. [...] [T]he nitrox diver can use the reduced absorption of nitrogen to increase allowable dive time by using the EAD to derive the no-decompression limit for the dive or as a basis for calculating decompression. This approach allows longer dives and shorter decompression.

2016, Carl Edmonds, Michael Bennett, John Lippmann, Simon J. Mitchell, “Technical Diving”, in Diving and Subaquatic Medicine, 5th edition, Boca Raton, Fla.: CRC Press, →ISBN, part 10 (Specialized Diving and Its Problems), page 705:

narced

en-adj

narced (comparative more narced, superlative most narced)

more narced (comparative)
most narced (superlative)

On his first dive, Ralph got really narced, and thought he was turning into a sea turtle.

While doing a test in a chamber to assess the pressure at which one will get narced seems like a great idea, it is not necessarily an indicator of who will get narced at what depth.

1996, Karen Burge, “(was: will you get narced?) maybe...maybe not”, in rec.scuba (Usenet):

There has been only one time that I felt narced and strangley it was in 127 of water.

1998, Ray Jones, “Narcosis”, in bit.listserv.scuba-l (Usenet):

2003:, uglymoney, Narcosis at 110? in rec.scuba
All went well. However I am absolutely convinced that I was narced.
