Stands for feet of fresh water. Measurement of depth in fresh water.


Kicking the feet rhythmically while wearing fins to product forward motion in the water.

First Stage

The main part of a scuba regulator. The first stage reduces the pressure of the air from the tank to 8-10 bar (140 psi) above ambient pressure. This allows the air to pass to the second stage for breathing by the diver. It is also supplies air to inflate the diver's BCD and to pressure gauges that display the remaining volume of air in the tank.

Foot Pocket

Kitchen on a boat.

Gas Embolism

See Arterial Gas Embolism (AGE).

Gas Analysis

A procedure used to determine the percentage of gas in a breathing mixture. It is normally used to determine the percentage of oxygen to within 1 %, to control the effects of oxygen toxicity. Most diving operations analyze for oxygen only. In Trimix's, it is be best to analyze for the inert gases as well.

Gas Laws

Laws that predict how gases will behave with changes in pressure, temperature and volume.

Gas Saturation

Gas saturation occurs when the level of dissolved gas in a particular body tissue has reached its maximum.

Gauge pressure

The surrounding water pressure measured by a gauge that does not take atmospheric pressure into account.

Giant Stride Entry

Haldane's theory that nitrogen is absorbed and released in an exponential manner during a dive, and that there is some safe ratio of pressure change for ascent.

Half Time

Half the time it takes for a dissolved gas in a tissue (such as nitrogen) to equilibrate to a new pressure, or to reach full saturation at a new pressure. Theoretical tissue half times are used in designing dive tables and algorithms for dive computers.


A Halocline is a change between layers of fluids of different densities. The most important to divers is the salt content of the water. This is not often apparent unless the change is big enough to cause buoyancy changes.

Hang Tank

An extra tank staged at the decompression stop. A hang tank found on the ascent line of a dive boat in case of emergencies.


Bathroom on a boat.


Mixture of helium and oxygen that is most commonly use for very deep diving.


Second lightest gas. Helium does not cause problems of narcosis to the same extent as seen with nitrogen, and is therefore used for very deep diving.

Henry's Law

The amount of any given gas that will dissolve in a liquid at a given temperature is a function of the partial pressure of the gas in contact with the liquid and the solubility coeffient of the gas in the liquid.

High Altitude Diving

Diving in mountain lakes or other high altitude waters at or greater than 1,000 feet (300 meters) above sea level. This type of diving has an increased risk of decompression sickness because of lower-than-sea-level atmospheric pressure at the surface. This requires special dive tables, dive computers and depth gauges. Specialty courses are available due to the complexity and added hazards of this activity.


Garment worn over the head to reduce thermal loss. .


A surface-supplied compressed air apparatus. This is used for diving in shallow, calm waters. The air is delivered to one or more divers through a long hose.

Hydrostatic Test

Pressure test in which the tank is filled with water instead of air and raised to five thirds the maximum working pressure, causing the water to expand and be displaced.

Hyperbaric Chamber

Air-tight chamber that can simulate the ambient pressure at altitude or at depth is used for treating decompression illness.


A body temperature warmer than normal. This is less common in diving than Hypothermia, but can occur from overheating in a wet suit.


Over breathing to the extent that the blood carbon dioxide level is lowered. This may lead to tingling in fingers and dizziness.


A subnormal chilling of the body.

Hypoxic and Hypoxia

In general, these terms relate to a more than a normal amount of Oxygen. Hypoxic refers to a mixture of gases with higher than normal Oxygen content (above 21%). Hypoxia is the physiological condition associated with breathing too high of a partial pressure of Oxygen. The human body has a limit on both the partial pressure of Oxygen it can tolerate and the long term dosage of Oxygen. The partial pressure upper limit is generally considered to be approximately 1.6 ppO2 but most divers leave some margin for error and a more typical upper limit is 1.4 ppO2. When high partial pressures of Oxygen are inspired, convulsions may occur with little or no warning.

Marco Photography

Marco photography is used to get close-up pictures of a subject. This requires Marco accessories that are attached to the camera's lens.


A standard mask consists of a single or double (one for each eye) panel of tempered glass inside a plastic frame. The frame has a silicone skirt that forms an air tight seal against the face. A strap and buckles hold the mask in place.

Mask Fogging

Misting on the inside of a diver's mask. This is due to the accumulation of oils on the inside of the lens. These oils allow moisture to form much quicker.

Mask Squeeze

A painful condition caused by increasing water pressure against the diver's mask, causing the mask to be pressed against the diver's face. This happens during a rapid descent when the diver does not equalize his/her mask. This condition can cause permanent eye damage if not equalized. To prevent this from happening, a diver should equalize every few feet (or meter) while descending slowly.

Mediastinal Emphysema

Air from an over expanding lung escapes into the center of the chest. This puts pressure on the heart and major blood vessels, interfering with circulation. Symptoms are shortness of breath and feeling faint.

Middle Ear

An air space of the ear bordered on one side by the tympanic membrane (eardrum). This membrane is exposed to any change in ambient pressure. Air pressure in the middle ear space can only be equalized through the Eustachian tube, which connects the middle ear to the back of the nose.

Middle Ear Barotrauma (Middle Ear squeeze)

Damage done to the middle ear when a diver fails to equalize. The eardrum flexes inward, causing pain and discomfort. Blood and fluid from the surrounding tissue is forced by the water pressure into the unequalized middle ear.

Mixed Gas

A breathing gas that contains altered percentages of oxygen and nitrogen, and also helium. Mixed gases (Trimix's) are used for dives below 165 feet (50 meters).

Multilevel Diving

Starting a dive at the deepest point, and then spending the remaining part of the dive at shallower depths. This will allow a diver to have a longer bottom time.

National Association of Underwater Instructors. NAUI is one of the oldest certifying agencies and is based in the United States.

Nautical Mile

A unit of distance designed to equal approximately 1 minute of arc of latitude, 6080.20 feet. A nautical mile is approximately 1.15 times as long as the statute mile of 5280 ft. Also known as a "geographical mile" or "sea mile".


A synthetic fabric with good heat insulation properties. Neoprene is used to make wetsuits.


An odorless, colorless and tasteless gas that makes up approximately 78% of the air. Nitrogen is inert (it does not enter into any chemical reaction in the body) but it can cause problems under pressure. (See nitrogen narcosis, decompression sickness).

Nitrogen Narcosis

Intoxication caused by breathing nitrogen at elevated partial pressures. This can happen on deep dives and can result in the impairment of reasoning and motor skills, feelings of irrational anxiety or elation, and perceptual narrowing. The effect can be reversed upon the return to a shallower depth.


A mixture of nitrogen and oxygen prepared for use as a breathing gas. Nitrox will contain a greater percentage of oxygen than that found in air.

No Decompression Limit (NDL)

A No Decompression Limit is the maximum bottom time at a given depth, at which a direct ascent to the surface is possible without having to do staged decompression stops and without sufficient risk of decompression sickness.
