Scientific diving is broad in scope but can help us understand many aspects of the world. Learn more about scientific diving.

Sidemount gear configuration creates a lower profile in the water enabling people to explore new environments easier. Sidemount is no longer considered something exclusive to tech divers and is moving into the recreational dive space.

Diving at night provides an exciting new dimension in underwater exploration. As the light fades and darkness spreads through the water, marine life exhibits different behaviors, and the underwater world takes on a new and ethereal quality.

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.

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.

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.

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 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.
