Anatomy of a Commercial Mixed-Gas Dive
The commercial diving industry adopted mixed-gas technology in the 1960s to overcome the limitations of deep air diving. The industry has an exemplary safety record.

Seeing the Reef in a New Light
Fluorescence night diving enables divers to observe marine life in glowing colors often invisible to the naked eye. Read more about this night diving technique and how fluorescence works.
Diving in Currents
Currents can by physically demanding for divers, and they can accelerate air usage. But, diving in currents can be a lot of fun! Read more about how to successfully dive in currents.
Diving in Remote Destinations
Whether your plans involve recreational or technical diving, hiring dive operators in remote locations requires several considerations — and there are additional safety factors to consider when going to these remote destinations.
Learning to Rebreathe
Rebreather diving can be tricky for recreational divers especially in terms of relearning buoyancy control. Rebreather diving also does not change the amount of gas in the system, but simply moves the volume of gas back and forth. Learn more about how one rec diver learnt rebreather diving.
Ice Diving
Ice diving is both politically and scientifically interesting and has received international research funding in the fields of medicine, physiology, fisheries and ecology. Read more about ice fishing.
Caissons, Compressed-Air Work and Deep Tunneling
Do you know how underground tunnels are made? The working spaces, or caissons, are pressurized with compress air. But in the 19th century, many laborers had an unexplained illness after returning to atmospheric pressure.
Aquarium Diving
Aquarium divers are crucial in keeping the habitats clean and the animals healthy. To be come an aquarium diver requires additional training and learning how to apply their old skills in new ways. Learn more about aquarium diving.
Estimating Your Air Consumption
Do you have enough breathing gas to complete the next dive? Here’s how to find out.
Breathing Gases
Some divers like closed-circuit rebreathers for their ability to provide breathing gas at a set partial pressure of oxygen throughout dives.
