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.
Some divers like closed-circuit rebreathers for their ability to provide breathing gas at a set partial pressure of oxygen throughout dives.
What is saturation diving? When the diver breathes in inert gas, it dissolves into the body’s tissues and reaches equilibrium with the ambient pressure at the diver’s depth.
Researchers test to see how rebreathers function in arctic environments. Read how a team of researchers aimed to explore this little-known subject.
Spearing fish has been a part of human sustenance since hunters first sharpened sticks. With the advent of masks and fins, spearfishing became its own activity. Whether for sport or to put food on the table, divers and freedivers seek these opportunities around the world.

What does it take to be a safety diver for Cirque du Soleil? With a 1.5-million-gallon, 25-foot-deep pool, these safety divers have to be ready for anything.
Get a deeper understanding of exploratory diving — a sometimes controversial topic. One team of divers schemed a plan to dive and explore a deep wreck. Read more about the process.
Expedition diving varies, but ultimately, they are complex adventures that require months of preparations and a team of dedicated individuals. Learn more about expedition diving.
Rebreathers do create an added complexity to a dive, but they can be incredibly useful. Learn more about how rebreathers work, benefits and challenges to their use and practical applications.
