Learning to Thrive in Extreme Environments

My phone’s alarm filled the air, but I was already awake. It was the day I had eagerly anticipated since first learning about the Florida International University (FIU) Introduction to Saturation Diving: Aquarius Operations and Benefits to Science course — the emergency simulation.

Technical Diving

Technical diving requires additional gear, training and knowledge, but once you become comfortable with tech diving, you can do a lot. Learn more about technical diving and if it is a right option for you.

Backplate Buoyancy Systems

More-experienced divers prefer the backplate buoyancy system because of its rock-solid stability and simple harness system. Read more about backplate buoyancy systems.

Advanced Underwater Navigation

Most divers’ love of the sport stems from a drive to explore a foreign environment. With exploration must come the ability to navigate. Nowhere else on Earth can one become more lost than in a liquid, while simultaneously requiring constant individual concentration on safety techniques, breathing gas, buoyancy, horizontal trim, depth, and time.

Successful navigation depends on one’s ability to master the basic fundamental skills of diving.

Sidemount — Not Just for Cave Divers Anymore

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.

Night Diving

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.

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.
