	trimiX.net: What Is Trimix
		Trimix is a combination of oxygen, helium and nitrogen.
		Trimix is frequently promoted as the holy grail of scuba diving, so horrifyingly complex that you must take 4-8 levels of training before you can use it.
		But it is possible to create a normoxic tank of trimix and treat it similar to air, without multiple mixes, bottles and other complexities, and enjoy the benefits of helium.

	trimix-diver
		The IANTD Trimix Diver programme is designed for those divers who are already involved in deep diving activities.
		Trimix affords a safer means for deep water exploration for divers who need to perform with a clear head at depth.
		In order to participate on the course students must be Technical or Normoxic Trimix divers and provide proof of at least 200 logged dives of which at least 25 were to depths between 39 and 60 metres.

	Reef Divers - Trimix Course (Site not responding. Last check: )
		Trimix affords a safer means for deep-water exploration for divers who must dive deep or perform with a clear head at the intermediate depths.
		Trimix is used in very deep dives instead of air to reduce the partial pressure of oxygen (to avoid oxygen toxicity) and nitrogen (to avoid nitrogen narcosis).
		Trimix mixes are labeled for example as "Trimix 10 50" or "Trimix 10/50", where 10 represents the percentage of oxygen in the mix, and 50 is the percentage of helium.

	2001-05 The Trouble with Trimix
		My reaction after returning from my first trimix dive in the early 1990s was, “This is just what we need.” In the past, I’d made working dives to 220 feet on air and had been fairly narced to say the least.
		During the 1990s, the tek diving community embraced trimix (oxygen, helium and nitrogen) as the accepted gas for diving deeper than 200 feet, and diving on air to 240 feet went from macho to moronic.
		Qualified tek divers switch to trimix as shallow as 100 feet for complex dives or dives in difficult environments.

	Trimix
		There are numerous wrecks in the Pacific northwest in trimix depths (150 to 300 fsw/ 45 to 91 msw) laying untouched and undiscovered, waiting to be explored by the first intrepid divers trained to penetrate their depths.
		Knowledge and understanding are gained through in-depth lectures on equipment configuration, breathing and physiological aspects of trimix diving, hypoxic and ascent mixtures, oxygen use and misuse, inert gas narcosis, carbon dioxide, dive planning, and decompression models and illness.
		Our Trimix course consists of 12 hours of lecture with a minimum of 100 minutes of bottom time to be completed in 1 pool session and 3-4 ocean dives (actual dive time realistically approaches 200 minutes).

	Technical Dive Training for Scientists at NURP's Caribbean Facility Gets Underway
		By using trimix, a combination of nitrogen, oxygen and helium, it is possible for divers to descend to hundreds of feet without suffering from toxic partial pressures of oxygen (which increase with depth), and also reduces the effect of nitrogen narcosis.
		After the divers completed the trimix and technical diving certification courses, four working dives were completed by 2 of the divers for a total of 60 minutes bottom time to depths up to 93 meters (308 feet), and over 400 minutes total runtime.
		However, using this advanced diving technology, Dr. Lesser is able to expand the scope of his research to deep reefs by using in situ methodology to compare phenotypic plasticity of deep water sponges found along a depth gradient down to 90 meters (300 feet) with sponges found at shallower depths.
